C Global Data Services Control Utility (GDSCTL) Command Reference

This appendix includes a complete reference of the Global Data Services utility (GDSCTL) commands for use with a Global Data Services or Oracle Globally Distributed Database configuration.

add brokerconfig

Adds an Oracle Data Guard broker configuration to a Global Data Services pool.

Syntax

add brokerconfig -connect connect_identifier 
                 [-pwd password]  
                 [-gdspool gdspool_name] 
                 [-region region_name] 
                 [-savename]
                 [-force]

Options

Table C-1 GDSCTL add brokerconfig Options

Option Description

-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for a database in the broker configuration.

-force

If specified, the existing GDS configuration is deleted. Deletes an existing, running SDB, and should only be used if you want to get rid of the entire SDB.

-gdspool gdspool_name

The pool to which the databases of the Oracle Data Guard broker configuration are to be added.

If the specified Global Data Services pool already contains databases or another configuration, GDSCTL returns an error.

-pwd password

The password for the GSMUSER. If -pwd is not specified, then you are prompted for the password.

-region region_name

The Global Data Services region to which the databases belong. If you specify a region, then all the databases are added to that region. If you do not specify a region, then all databases are added with a region of UNASSIGNED. If the region is UNASSIGNED, then you must use the modify database command to change the region.

-savename

Specify this option to store a net service name specified with the -connect option in the Global Data Services catalog, rather than the connect descriptor mapped to that net service name.

Usage Notes

  • You must connect to the Global Data Services catalog database as a user with the pool administrator privileges, the GSMUSER database account, using the connect command before running the add brokerconfig command. You should use the CONNECT command to connect to the GSMUSER for the database that you are adding the broker configuration for.

  • If a GDS pool already has databases or another configuration, an error is returned. If -region is specified, it defines only the region of primary database. If there is more than one region in catalog, GDS region property of standbys will be unassigned. The user will have to use modify database to specify GDS region.

Examples

Add the Oracle Data Guard broker configuration for the DB1 database to the Global Data Services pool MYREADERFARM and the WEST region.

GDSCTL> add brokerconfig -connect 192.168.1.1:1521:sid -region west -gdspool myreaderfarm

Exceptions or Error Codes

GDSCTL returns the errors listed below if you use this command incorrectly.

Table C-2 GDSCTL add brokerconfig Exceptions or Error Codes

Exception Description

ERROR-44866

A pool can only contain one Data Guard broker configuration. If a Global Data Services pool already contains an Oracle Data Guard broker configuration, then GDSCTL returns error 44866 because a database must be added using Oracle Data Guard in this case.

add cdb

Add a cdb to the shard catalog.

Syntax

add cdb -connect connect_identifier
         [-pwd gsmrootuser_pwd]
         [-savename]
         [-cpu_threshold cpu]
         [-disk_threshold disk]
         [-rack rack_id]
         [-force]

Options

Table C-3 GDSCTL add cdb Options

Option Description
-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for the database being added as the shard.

-pwd gsmrootuser_pwd

Enter the GSMROOTUSER password. If not specified, the user is prompted for the password.

-savename

Store in the shard catalog a net service name specified with the -connect option rather than the connect descriptor mapped to that net service name.

-force

If specified, the existing GDS and sharding configuration on the shard and in the shard catalog with information about this shard will be rewritten.

-cpu_threshold cpu

Specify the CPU Utilization percentage threshold.

-disk_threshold disk

Specify the average latency in milliseconds of a synchronous single-block read.

-rack rack_id

Specify an identifier of a rack (hardware cabinet), or another physical grouping of nodes with similar availability characteristics. If specified, GDS will enforce that databases that contain replicated data are not placed in the same rack. If this is not possible an error is raised.

Usage Notes

ADD CDB adds metadata about a CDB to a sharding catalog. This command is only necessary if you intend to deploy a PDB as a shard with the -cdb option in the ADD SHARD command. CDBs can support multiple PDB shards from different sharded databases; however, this support is limited to only one PDB shard from a given sharded database for each CDB.

Examples

Adds a CDB called db11 to the shard catalog.

GDSCTL> add cdb -connect db11 -pwd gsmrootuser_pwd

add credential

Adds a credential which can be used by the remote scheduler agent to execute shard jobs.

Syntax

add credential -credential credential_name 
               -osaccount account_name
               -ospassword password
              [-windows_domain domain_name]

Options

Table C-4 GDSCTL add credential Options

Option Description

-credential credential_name

Specify the name of the credential to add.

-osaccount account_name

Specify the operating system account which will be used for remote jobs.

-ospassword password

Specify the corresponding password for the account.

-windows_domain domain_name

If a Windows account has been specified, specify the corresponding domain name for that account.

Usage Notes

This command adds a credential which will be used to execute jobs on sharded hosts in response to administrative commands. The operating system account may be any valid account on the remote host which is in the OSDBA group; the account does not need to be enabled for interactive login unless it is used for other purposes. A specific non-interactive account may be created for use with the remote scheduler, if desired. The OS password must be a valid and current password for the specified account.

If the specified credential already exists, the command returns an error.

Examples

Add a credential named east_region_cred.

GDSCTL> add credential –credential east_region_cred –osaccount agent_user
 –ospassword password

add database

Adds databases to a Global Data Services region and Global Data Services pool.

Syntax

add database -connect connect_identifier 
            [-region region_name]
            [-gdspool gdspool_name]
            [-pwd password]
            [-savename]
            [-cpu_threshold cpu] 
            [-disk_threshold disk]
            [-validate_network]

Options

Table C-5 GDSCTL add database Options

Option Description

-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for the database being added.

-cpu_threshold cpu

Specifies CPU Utilization percentage threshold.

-disk_threshold disk

Specifies the average latency in milliseconds of a synchronous single-block read.

-gdspool gdspool_name

The Global Data Services pool to which the database belongs.

-pwd password

The password for the GSMUSER. If -pwd is not specified, then you are prompted for the password.

-region region_name

The Global Data Services region to which the database belongs.

-savename

Specify this option to store a net service name specified with the -connect option in the Global Data Services catalog, rather than the connect descriptor mapped to that net service name.

-validate_network

This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

  • You must connect to the Global Data Services catalog database as a user with the pool administrator privileges, using the connect command before running this command.

  • If -savename is not specified, then GDSCTL replaces what you specify for the net service name with the full connection string before saving the configuration to the catalog.

  • The default for GDSCTL is for autovncr to be enabled for the catalog. If autovncr has been disabled for the catalog, before configuring Global Data Services pools and adding databases to the Global Data Services configuration, the nodes where those databases run must be part of the valid node checking for registration (VNCR) list for database registration. Use the add invitednode (add invitedsubnet) command to define the valid nodes.

Example

Adds database DB1 to the WEST region and Global Data Services pool MYREADERFARM.

GDSCTL> add database -connect 127.0.0.1:1521:db1 -region west -gdspool
   myreaderfarm

Adds a database using myalias instead of the IP address connection string.

GDSCTL> add database -connect myalias -gdspool myreaderfarm

Exceptions or Error Codes

GDSCTL returns the errors listed below if you use this command incorrectly.

Table C-6 GDSCTL add database Exceptions or Error Codes

Exception Description

ERROR-44866

If a pool already contains an Oracle Data Guard broker configuration, then GDSCTL returns an error; you must add databases using Oracle Data Guard in this case. That is, if a pool contains an Oracle Data Guard broker configuration, then additional databases can only be added to the pool by adding them to that Data Guard broker configuration.

ERROR-44868

If the database being added is part of a Oracle Data Guard broker configuration, then GDSCTL returns an error; you must use the add brokerconfig command in this case.

add file

Adds the contents of a file to the catalog which can be used by subsequent GDSCTL commands.

Syntax

add file -file file_name 
         -source local_filename

Options

Table C-7 GDSCTL add file Options

Option Description
-file file_name

Specify the name of the file object to add.

-source local_filename

Specify an operating system file name specifying a file local to the machine running GDSCTL.

Usage Notes

This command creates a named file object in the catalog and associates the contents of an operating system file with that object by opening the file and storing its contents in the catalog. If the contents of the operating system file change, the MODIFY FILE command can be used to reload the contents into the catalog.

If the specified file object already exists, the command returns an error.

Examples

Add a file named east_region_db_params from the local source file /tmp/dbca_params.txt

GDSCTL> add file -file east_region_db_params -source /tmp/dbca_params.txt

add gdspool

Adds a Global Data Services pool to the Global Data Services framework.

Syntax

add gdspool -gdspool gdspool_name_list 
           [-users user_list]

Options

Table C-8 GDSCTL add gdspool Options

Option Description

-gdspool gdspool_name_list

A comma-delimited list of Global Data Services pool names.

A Global Data Services pool must have a unique name within its GDS configuration. If you do not specify a name for the pool when you create it, then the name defaults to oradbpool. The pool name can be up to 30 bytes long and can be any valid identifier (an alphabetical character followed by zero or more alphanumeric ASCII characters or the underscore (_)).

-users user_list

A comma-delimited list of users that are granted the pool administrator role.

Usage Notes

  • A default GDS pool, DBPOOLORA, will be created automatically when a GDS catalog is created using create gdscatalog.

  • You must connect to the Global Data Services catalog database as a user with the Global Data Services administrator privileges, using the connect command before running this command.

  • The default for GDSCTL is for autovncr to be enabled for the catalog. If autovncr has been disabled for the catalog, then before configuring Global Data Services pools and adding databases to the Global Data Services configuration, the nodes where those databases run must be part of the valid node checking for registration (VNCR) list for database registration. Use the add invitednode (add invitedsubnet) command to define the valid nodes.

Example

Add a Global Data Services pool named MYREADERFARM to the configuration:

GDSCTL> add gdspool -gdspool myreaderfarm

add gsm

Adds a global service manager to the Global Data Services framework.

Syntax

add gsm -gsm gsm_name
        -catalog connect_id
       [-pwd password]
       [-wpwd password]
       [-region region_name]
       [-localons ons_port]
       [-remoteons ons_port]
       [-listener listener_port]
       [-endpoint gmsendpoint]
       [-remote_endpoint remote_endpoint]
       [-trace_level level]
       [-encryption encryption]
       [-validate_network] 

Options

Table C-9 GDSCTL add gsm Options

Option Description

-catalog connect_id

Specify the connect identifier for the Global Data Services catalog database. If a network service name is specified, it must be resolvable by the local naming method to a connect descriptor that allows the global service manager being added to connect to the catalog database.

-endpoint gsmendpoint

Specifies the protocol address that the global services manager listens on for client connection requests. If you use this option, the value that you specify overrides the default endpoint.

-gsm gsm_name

Specify the name of the global service manager that you want to add. If you do not specify a name, then GDSCTL uses the current global service manager name for the session (specified with the command set gsm.

-listener listener_port

Specify the listener port. The default port is 1522.

-localons ons_port

Specify the local ONS port. If you do not specify this option, then GDSCTL uses the default ONS port (which is 6123 on most platforms).

-pwd password

Specify the password for the GSMCATUSER. If you do not specify a password, then you are prompted to enter one.

-region region_name

Specify the region to which the global service manager belongs. The value for region_name must match the name of an existing Global Data Services region. If you do not specify a region, then GDSCTL adds the global service manager without assigning a region.

-remote_endpoint remote_endpoint

Specifies the protocol address that is used by the global service manager to receive database registration requests and communicate with other global service managers in the configuration. If you use this option, the value that you specify overrides the default endpoint.

-remoteons ons_port

Specify the remote ONS port. If you do not specify this option, then GDSCTL uses the default ONS port (which is 6234 on most platforms).

-trace_level level

Specify the global service manager trace level (to be used as directed by Oracle Support Services).

-wpwd password

Specify a password to protect the global service manager wallet. If a wallet password is not specified, a system-generated password is used instead. Note that if a password is specified with this option, the wallet cannot be modified without supplying that password.

-encryption encryption

Encryption protocol for Advanced Network Option (ANO) used between GSM, GDSCTL and databases. OFF means that ANO is disabled. ( AES256 | AES192 | OFF).

-validate_network This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

  • You must specify the Global Data Services catalog database when using this command.

  • You must run this command, locally, on the computer where you want to add the global service manager.

  • You must have operating system privileges on the computer where you want to add the global service manager to run this command.

  • When you run this command, GDSCTL connects to the Global Data Services catalog as the GSMCATUSER user and prompts you for the GSMCATUSER password.

Example

Add a global service manager named gsm1, specifying the location of the Global Data Services catalog database, DB1.

GDSCTL> add gsm -gsm gsm1 -catalog 127.0.0.1:1521:db1

add invitednode (add invitedsubnet)

Adds host address or subnet information to the valid node checking for registration (VNCR) list in the catalog, before starting the first global service manager, by establishing a direct connection to the Global Data Services catalog database.

Syntax

add {invitednode | invitedsubnet}
            [-group group_name] 
            [-catalog catalog_dbname [-user user_name/password]]
          vncr_id
            [-validate_network]

Options

Table C-10 GDSCTL add invitednode (add invtitedsubnet) Options

Option Description

-catalog catalog_dbname

Specify the Global Data Services catalog database net alias or connect string. If you enter an invalid address or connect string, then GDSCTL uses the pre-established connection created with the connect command.

-group group_name

Specify an alias which defines a group of invited nodes. This alias can be referenced in other commands related to invited nodes.

-user user_name[/password]

Specify the user credentials for the Global Data Services administrator in the catalog database. If you do not specify a user or a password, then GDSCTL prompts you this information.

vncr_id

Specify the list of nodes that can register with the global service manager. The list can include host names or CIDR notation for IPv4 and IPv6 addresses. The wildcard format (*) is supported for IPv4 addresses. The presence of a host name in the list results in the inclusion of all IP addresses mapped to the host name. The host name should be consistent with the public network interface.

-validate_network

This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

  • You must connect to the Global Data Services catalog database as a user with the pool administrator privileges, using the connect command before running this command.

  • The default for GDSCTL is that autovncr is enabled for the catalog. If autovncr has been disabled for the catalog, before configuring Global Data Services pools and adding databases to the Global Data Services configuration, then the nodes where those databases run must be part of the valid node checking for registration (VNCR) list for database registration. Use the add invitednode (add invitedsubnet) command to define the valid nodes.

  • VNCR enables or denies access from specified IP addresses to Oracle services. See Oracle Database Net Services Administrator's Guide for more information about VNCR.

Examples

Add the netmask 255.255.255.248 to the catalog.

GDSCTL> add invitednode 255.255.255.248 

Add the server east1.example.com to the catalog in the alias group EAST_SRV.

GDSCTL> add invitednode east1.example.com

Add the server east2.example.com to the catalog in the alias group EAST_SRV.

GDSCTL> add invitednode east2.example.com

add region

Adds a region to a Global Data Services framework or an Oracle Globally Distributed Database configuration.

Syntax

add region -region region_list 
          [-buddy region_name]

Options

Table C-11 GDSCTL add region Options

Option Description

-buddy region_name

Specify the name of the buddy region.

-region region_list

Specify a comma-delimited list of Global Data Services region names.

A Global Data Services region should have a name that is unique within the corresponding Global Data Services configuration. If no name is specified at the first region creation time, the default name, oraregion, is given to the region. The region name can be up to 30 characters long and can be any valid identifier - an alphabetical character followed by zero or more alphanumeric ASCII characters or underscore (_).

Usage Notes

  • When the Global Data Services catalog is created using the create gdscatalog command, the default REGIONORA region is created automatically.

  • You must connect to the Global Data Services catalog database as a user with the Global Data Services administrator privileges, using the command connect before running this command

Example

Add two Global Data Services regions, EAST and WEST to the current configuration:

GDSCTL> add region -region east,west

add service

Adds a global service to a Global Data Services pool.

Syntax

add service
           [-gdspool gdspool_name]

           [-reset_state {NONE|LEVEL1|LEVEL2|AUTO}]

Options

Table C-12 GDSCTL add service Options

Option Description

-available dbname_list

Specify a comma-delimited list of available databases on which the service runs if the preferred databases are not available. You cannot specify a list of available instances, only databases. You can use the modify service command with the -server_pool parameter to specify instance-level preferences.

The list of available databases must be mutually exclusive with the list of preferred databases.

You cannot use this option with the -preferred_all option.

-clbgoal {SHORT | LONG}

Connection Load Balancing Goal. Use a value of SHORT for this parameter for run-time load balancing, or if using an integrated connection pool. Use a value of LONG for this parameter for long running connections, such as batch jobs, that you want balanced by the number of sessions for each node for the service.

The default value for this option, if not specified, is SHORT.

-commit_outcome {TRUE | FALSE}

Enable Transaction Guard; when set to TRUE, the commit outcome for a transaction is accessible after the transaction's session fails due to a recoverable outage.

—drain_timeout

Set drain time in seconds.

-dtp {TRUE | FALSE}

Indicates whether Distributed Transaction Processing should be enabled for this service. This service can either be a service in a policy-managed database or a preferred service on a single node in an administrator-managed database.

-edition edition_name

Specify the initial session edition of the service.

When an edition is specified for a service, all subsequent connections that specify the service use this edition as the initial session edition. However, if a session connection specifies a different edition, then the edition specified in the session connection is used for the initial session edition.

GDSCTL does not validate the specified edition name. During connection, the connect user must have USE privilege on the specified edition. If the edition does not exist or if the connect user does not have USE privilege on the specified edition, then an error is raised.

-failover_primary

If you set the -role option to PHYSICAL_STANDBY, then you can use this option to enable the service for failover to the primary database.

-failoverdelay failover_delay

For Application Continuity and TAF, this parameter specifies the time delay (in seconds) between reconnect attempts for each incident at failover.

-failovermethod {NONE | BASIC}

TAF failover method (for backward compatibility only).

If the failover type (-failovertype) is set to a value other than NONE, then you should choose BASIC for this parameter.

-failoverretry failover_retries

For Application Continuity and TAF, this parameter determines the number of attempts to connect after an incident.

-failovertype {NONE | SESSION | SELECT | TRANSACTION}

Specify the failover type.

To enable Application Continuity for Java, set this parameter to TRANSACTION. To enable Transparent Application Failover (TAF) for OCI, set this parameter to SELECT or SESSION.

-gdspool gdspool_name

Specify the name of the Global Data Services pool to which you want to add a service. If the pool name is not specified and there is only one gdspool with access granted to the user, then this the gdspool with access granted is used as the default gdspool.

-lag {lag_value | ANY}

Specify the lag for the service in seconds. You can use the keyword ANY to indicate that there is no upper threshold on the lag time. This parameter specifies the maximum lag that a provider of this service may have. The service cannot be provided by a database whose lag exceeds this value.

The default value for lag, if not specified, is ANY.

-locality {ANYWHERE | LOCAL_ONLY}

Specify the service region locality. If you do not specify this option, then GDSCTL uses the default value of ANYWHERE for the service.

-notification {TRUE | FALSE}

Enable Fast Application Notification (FAN) for OCI connections.

-pdbname pdb_name

Specify the pluggable database name.

-policy {AUTOMATIC | MANUAL}

Specify the management policy for the service.

If you specify AUTOMATIC (the default), then the service automatically starts when the database restarts, either by a planned restart or after a failure. Automatic restart is also subject to the service role.

If you specify MANUAL, then the service is never automatically restarted upon planned restart of the database. A MANUAL setting does not prevent the global service manager from monitoring the service when it is running and restarting it if a failure occurs.

-preferred dbname_list

Specify a comma-delimited list of preferred databases on which the service runs. You cannot specify preferred instances, only databases. You can use the modify service command to specify instance-level preferences.

The list of preferred databases must be mutually exclusive with the list of available databases.

You cannot use this option with the -preferred_all option.

-preferred_all

Specifies that all the databases in the Global Data Services pool are preferred databases. Any databases you later add to the pool are configured as preferred databases for this service.

You cannot use this option with the -preferred and -available options.

-region_failover

Indicates that the service is enabled for region failover. You can only use this option when you specify LOCAL_ONLY for the -locality option.

-replay_init_time replay_init_time

For Application Continuity, this parameter specifies the time (in seconds) after which replay cannot be initiated. The default value is 300 seconds.

-retention retention_seconds

If commit_outcome is set to TRUE, then this parameter determines the amount of time (in seconds) that the commit outcome is retained in the database.

-rlbgoal {SERVICE_TIME | THROUGHPUT}

Run-time Load Balancing Goal (for the Load Balancing Advisory). Set this parameter to SERVICE_TIME to balance connections by response time. Set this parameter to THROUGHPUT to balance connections by throughput.

If you do not use this option, then the value defaults to SERVICE_TIME for the run-time load balancing goal.

-role {[PRIMARY] | [PHYSICAL_STANDBY] [-failover_primary] | [LOGICAL_STANDBY] |[SNAPSHOT_STANDBY]}

Specify the database role that the database must be for this service to start on that database. This applies only to Global Data Services pools that contain an Oracle Data Guard broker configuration.

See Also: Oracle Data Guard Concepts and Administration for more information about database roles

-service service_name

Specify the name of the global service.

The service name specified in the add service command can be domain qualified (for example, sales.example.com) or not (for example, sales). If the specified name is not domain qualified, the service is created with the default domain name <GDS_pool_name>.<GDS_configuration_name>, however the shorter non-domain qualified name can be used with subsequent gdsctl commands to manage the service. If the specified name is domain qualified, the full domain qualified service name must be used in all subsequent gdsctl commands used to manage the service.

A global service name must be unique within a GDS pool and when qualified by domain, must also be unique within a GDS configuration. A global service cannot be created at a database if a local or global service with the same name already exists at that database.

A global service name can contain alphanumeric characters, underscore (_), and period (.). The first character must be alphanumeric. The maximum length of a global service name is 64 characters. The maximum length of a domain qualified global service name is 250 characters.

An Oracle Net connect descriptor used to connect to a global service must contain a domain qualified service name.

-session_state {DYNAMIC | STATIC}

For Application Continuity, this parameter specifies whether the session state that is not transactional is changed by the application. A setting of DYNAMIC is recommended for most applications.

-sql_translation_profile stp_name

Use this option to specify a SQL translation profile for a service that you are adding after you have migrated applications from a non-Oracle database to an Oracle database.

This option corresponds to the SQL translation profile parameter in the DBMS_SERVICE service attribute.

Notes:

  • Before using the SQL translation feature, you must migrate all server-side application objects and data to the Oracle database.

  • Use the command config service to display the SQL translation profile.

See Also: Oracle Database SQL Translation and Migration Guide for more information about SQL translation

—stop_option

Set the default stop option to NONE, IMMEDIATE, or TRANSACTIONAL

-table_familyfamily

Specifies the name of the table family as a property of the service. This parameter takes one of the table family values (root table schema.name) as shown in the CONFIG TABLE FAMILY output.

If the schema name or the table name is case-sensitive, use two-level quotes (single quotes outside, double quotes inside) around the whole string, for example, '"TESTUSER1.Customers6"'. No quotes are needed if neither name is case sensitive.

If this parameter is not specified, but there is currently only one table family, the service created with the add service command is automatically associated with that table family.

-tafpolicy {BASIC | NONE }

TAF policy specification (for administrator-managed databases only).

-failover_restore

Session state restoration for Application Continuity (NONE | LEVEL1 | AUTO)

-reset_state

Reset session state (NONE -default | LEVEL1 | LEVEL2 | AUTO)

Usage Notes

Database-specific options cannot be set at this level. The modify service command must be used to set database-specific options.

One of -preferred_all or -preferred must be specified. If -preferred_all is specified, then all databases in the pool are preferred for this global service (databases inserted into the pool will also have this global service added).

In Oracle Sharding, note that when there is no table_family parameter specified, the service is not associated with any table family, and the value of the property is set to NULL. This is the case for user-defined and composite sharding, where there is always only one table family, and can also be the case when there is only one table family in system-managed sharding. When a table family is deleted (that is, the root table of the table family is dropped) the table_family property of the service is reset to NULL.

Examples

Note:

In Database 23ai, the session attribute values FAILOVER_TYPE = TRANSACTION with SESSION_STATE_CONSISTENCY = STATIC are no longer a supported service attribute combination. Instead use one of the following combinations in the service configuration: FAILOVER_TYPE = AUTO with SESSION_STATE_CONSISTENCY = AUTO or FAILOVER_TYPE = TRANSACTION with SESSION_STATE_CONSISTENCY = DYNAMIC These configurations enforce session state tracking in the Oracle database ensuring that session state is preserved at session migration and session failover.

Add a service named sales_report to the Global Data Services pool MYREADERFARM with a value of ANYWHERE for the locality.

GDSCTL> add service -gdspool myreaderfarm -service sales_report -locality ANYWHERE

Add a service named daily_sales_rept to the Global Data Services pool MYDGPOOL with preferred instance set to DB1 and the available instances set to DB3 and DB4. The service should use the basic transaction failover policy.

GDSCTL> add service -gdspool mydgpool -s daily_sales_rept -preferred db1 
  -available db3,db4 -tafpolicy BASIC

In a system-managed sharded database, the table family ID parameter is specified as a property of the service.

GDSCTL> add service –gdspool shdpool –table_family sales.customer -service sales –preferred_all -locality ANYWHERE

add shard

Add a shard to the shard catalog.

Syntax

add shard -connect connect_identifier
         [-pwd password]
         [-savename]
         [-region region_name] 
         [-force]
         [-cdb cdb_name] 
         [-cpu_threshold cpu]
         [-disk_threshold disk]
         [{-shardgroup shardgroup_name | -shardspace shardspace_name}]
         [-deploy_as {PRIMARY | STANDBY | ACTIVE_STANDBY}]
         [-rack rack_id]
         [-replace old_db_name]         
         [-gg_service (http|https):ogg_host:sm_port/GGHOME_directory]
         [-validate_network]

Options

Table C-13 GDSCTL add shard Options

Option Description
-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for the database being added as the shard.

-pwd password

Enter the GSMUSER password. If not specified, the user is prompted for the password.

-savename

Store in the shard catalog a net service name specified with the -connect option rather than the connect descriptor mapped to that net service name.

-region region_name

Specify the GDS region that this shard belongs to. This parameter is only valid for user-defined sharding. For other sharing methods it is specified per shardgroup.

-force

If specified, the existing GDS and sharding configuration on the shard and in the shard catalog with information about this shard will be rewritten.

-cdb cdb_name

If this parameter is used, the shard must be a PDB and the CDB must already exist in the catalog.

-cpu_threshold cpu

Specify the CPU Utilization percentage threshold.

-disk_threshold disk

Specify the average latency in milliseconds of a synchronous single-block read.

{-shardgroup shardgroup_name | -shardspace shardspace_name}

Specify the name of the shardgroup or shardspace that this shard is being added to.

Use -shardspace when using this command in a user-defined sharding configuration. Use -shardgroup with system-managed and composite sharding configurations.

-deploy_as {PRIMARY | STANDBY | ACTIVE_STANDBY}

Specify the role that is assigned to a shard added to the shardgroup after deployment. This parameter is only used with Data Guard replication. The specified role will be assigned to the shard database after deployment. The valid values are:

  • PRIMARY – the shard should be deployed as the primary database

  • STANDBY – the shard should be deployed as a Data Guard standby (mounted)

  • ACTIVE_STANDBY – the shard should be deployed as an Active Data Guard standby

If the parameter is not specified, the default value is STANDBY

-rack rack_id

Specify an identifier of a rack (hardware cabinet), or another physical grouping of nodes with similar availability characteristics. If specified, GDS will enforce that databases that contain replicated data are not placed in the same rack. If this is not possible an error is raised.

—replace old_db_name

This parameter specifies db_unique_name of the old shard when replacing it. The existing parameters of the ADD SHARD command (such as connect) must refer to attributes for the new (replacement) shard.

This parameter is not supported in an Oracle GoldenGate environment.

-gg_service (http|https):ogg_host:sm_port/deployment

This parameter is mandatory for Oracle GoldenGate replication and specifies the URI for the GoldenGate Admin Server that will manage the GoldenGate replication at this shard. The format will be as follows Example:

shard1.example.com:9005/shard1.

-validate_network This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

Before running add shard, you must validate the shard by running the validateShard procedure as described in Oracle Globally Distributed Database Guide

  • The shard will become part of the sharded database after a DEPLOY command is executed, except in the case of -replace.

  • Any databases added to a sharding configuration using ADD SHARD must not have ever been deployed as a shard in another configuration (unless -replace is specified). Re-adding a previously deployed shard will cause the ADD SHARD command to succeed, but the shard will be unable to successfully deploy and register with the shard director (GSM) when the DEPLOY command is eventually run.
  • ADD SHARD only registers the database (shard) with GDS. Replication is not configured on a newly added database and data from other databases is not distributed to it until DEPLOY is run.

  • With the introduction of Oracle Database 23ai, The default behavior when adding a shard to the topology has changed so that a current version of the schema is captured and applied on the new shard. Previously, all accumulated DDL on the sharded database was applied to the new shard, one by one in order, some of which might be negated by later DDL
  • With Data Guard replication, a shard can be added as a standby to a preexisting Data Guard configuration. There is no need to re-shard the data. It is expected that the shard being added is in a the correct state for configuration; the standbys should be cloned from the primary and have the same DBID. When you run DEPLOY, the existing primary and standby databases are matched with each other, using the DBID to form a broker configuration. If the broker has not been configured, it is configured, otherwise it is validated that it has been configured correctly. Once the broker is configured, Data Guard does its work, and it should be able to perform catch-up on the standbys if needed before bringing them online. Note that the broker is not configured for a federated database.

  • The -DEPLOY_AS option cannot be used in conjunction with -SHARDGROUP for system/composite sharding.
  • See Working with Oracle GoldenGate Sharding in the Fusion Middleware Using the Oracle GoldenGate Microservices Architecture guide for more information about using Oracle GoldenGate with Oracle Globally Distributed Database.

  • When using the- replace parameter, see Oracle Globally Distributed Database Guide for more information about its usage.

Note: Oracle GoldenGate replication support for Oracle Sharding High Availability is deprecated in Oracle Database 21c.

Examples

Add the shard to shardgroup GROUP1 of the DB11 database.

GDSCTL> add shard –connect db11 –shardgroup group1

Replace shard SH1 with database DB11.

GDSCTL> add shard –replace sh1 –connect db11

add shardgroup

Add a shardgroup to a shardspace.

Syntax

add shardgroup -shardgroup shardgroup_name 
              [-region region_name] 
              [-shardspace shardspace_name]
              [-deploy_as {PRIMARY | STANDBY | ACTIVE_STANDBY}]
              [-repfactor number]

Options

Table C-14 GDSCTL add shardgroup Options

Option Description

-shardgroup shardgroup_name

Specify the name of the shardgroup. The name must be unique across all shardspaces.

The shardgroup name can be up to 30 characters long and can be an alphabetical character followed by zero or more alphanumeric ASCII characters or an underscore (_).

-region region_name

Specify the name of the region. If not specified, a default region will be used.

-shardspace shardspace_name

Specify the name of the shardspace to which to add the shardgroup.

-deploy_as {PRIMARY | STANDBY | ACTIVE_STANDBY}

Specify the role that is assigned to a shard added to the shardgroup after deployment. This parameter is only used with Data Guard replication. The valid values are:

If the parameter is not specified, the default value is STANDBY

  • PRIMARY – the shard should be deployed as the primary database

  • STANDBY – the shard should be deployed as a Data Guard standby (mounted)

  • ACTIVE_STANDBY – the shard should be deployed as an Active Data Guard standby

-repfactor number

Specify the replication factor - the number of replicas for each piece of data stored in this shardgroup. This parameter can only be used with Oracle GoldenGate replication and is mandatory unless the default value of replication factor was specified in CREATE SHARDCATALOG command. This parameter does not apply to user-defined sharding because GoldenGate does not support that sharding methods.

Usage Notes

This command can only be used with system-managed or composite sharding, not user-defined sharding.

See Working with Oracle GoldenGate Sharding in the Fusion Middleware Using the Oracle GoldenGate Microservices Architecture guide for more information about using Oracle GoldenGate with Oracle Globally Distributed Database.

Note: Oracle GoldenGate replication support for Oracle Sharding High Availability is deprecated in Oracle Database 21c.

Examples

Add the GROUP1 shardgroup in the WEST region within the GOLD shardspace.

GDSCTL> add shardgroup -shardgroup group1 -region west –shardspace gold

add shardspace

Add a shardspace to the shard catalog.

Syntax

add shardspace -shardspace shardspace_name 
              [-chunks number] 
              [-protectmode dg_protection_mode]
              [repfactor][repunits]

Options

Table C-15 GDSCTL add shardspace Options

Option Description
-shardspace shardspace_name

Specify the name of the shardspace.

The shardspace name can be up to 30 characters long and can be an alphabetical character followed by zero or more alphanumeric ASCII characters or an underscore (_).

-chunks number

Specify the number of unique chunks in the shardspace. The value of -chunks must be greater than 2 times the size of the largest shardgroup in any shardspace.

This parameter does not apply to user-defined sharding or a federated database. All shardgroups in a shardspace have the same number of chunks. If this parameter is not specified, the default number of chunks is determined at the time of execution of the first DEPLOY command and is 120 per database of the shardgroup with the biggest number of databases.

-protectmode dg_protection_mode

Specify the Data Guard protection mode: MAXPROTECTION, MAXAVAILABILITY,or MAXPERFORMANCE (default). This parameter does not apply to Oracle GoldenGate replication.

-repfactor

Replication factor (the number of replicas for each piece of data stored in a shardgroup). This parameter can only be used with NATIVE replication and system-managed or composite sharding, and is mandatory in these cases. It doesn't apply to user-defined sharding or a federated database since there are no shardgroups in this case.

-repunits

Total number of replication units (SNR only).

Usage Notes

The command is applicable to user-defined sharding, composite sharding that assumes multiple shardspaces, and system managed sharding when there are no other shardspaces present in the current configuration.

Examples

Add the GOLD shardspace with Data Guard MAXAVAILABILITY protection mode.

GDSCTL> add shardspace –shardspace gold –protectmode maxavailability

alter move

Suspend, resume, or cancel scheduled chunk move operations on a sharded database.

Syntax

ALTER MOVE {-RESUME|-SUSPEND|-CANCEL}
         [-CHUNK {chunk_id_list}]
         [-SHARD shd_lst]
         [-verbose] 
         

Options

Table C-16 GDSCTL ALTER MOVE Options

Option Description
-cancel

Removes chunks from the pending chunk moves list for the specified scope.

-chunk chunk_id_list

List comma separated numeric chunk identifiers or use ALL for all chunks in the sharded database.

-resume

Resumes (reschedules) chunk moves which are in the "move failed" state for the specified scope.

-shard shd_lst

A comma separated list of shards.

-suspend

Suspends pending chunk moves for the specified scope.

-verbose

Enables verbose output mode.

Usage Notes

Suspending chunk moves: Use ALTER MOVE -SUSPEND to postpone a pending chunk move.

Resuming chunk moves: Use ALTER MOVE -RESUME to place specified chunk moves that are suspended or stalled (in the "move failed" state) into the "scheduled" state, effectively rescheduling them.

Canceling chunk moves: Use ALTER MOVE -CANCEL to cancel pending chunk moves. Once a chunk move operation is canceled it cannot be resumed or suspended.

Use the -chunk and -shard options to filter the scheduled chunk move operations. Use the -chunk option to target specific chunk IDs, and use the -shard option to target all chunk moves scheduled to occur to and from the specified database.

You can use the CONFIG CHUNKS command to get a list of pending chunk moves.

Chunk moves that are already in process cannot be suspended or canceled. If any chunk in scope for the ALTER MOVE operation is already in any state other than "scheduled" a warning is returned indicating that the move operation for that chunk was not altered.

Examples

Suspend all pending chunk moves:

ALTER MOVE -SUSPEND

Resume (reschedule) move operations for chunks 3 and 4:

ALTER MOVE -RESUME -CHUNK 3,4

Cancel all pending chunk moves to and from shard SH_1:

ALTER MOVE -CANCEL -SHARD SH_1

alter task

Suspend, resume, or cancel scheduled chunk or replication unit management operations on a sharded database.

Syntax

ALTER TASK
         {-RESUME|-SUSPEND|-CANCEL}
         [ -TASK task | [[-CHUNK chunk_id_list] |  [-RU ru_lst] | [-SHARD shard]]]
         [-verbose]] 
         

Options

Table C-17 GDSCTL alter task Options

Option Description
-cancel

Removes chunks for the specified scope from the scheduled list. "-chunk" specifies that all listed chunks will be removed, "-shard" specifies that all chunk moves to/from this database will be removed. If any chunk in scope is already in a move a warning is returned indicating that the chunk was not removed.

-chunk

List of numeric chunk identifiers or ALL for all chunks.

-resume

Restarts stalled move process, optional parameter "-shard" provides a list of databases that will have their "move failed" flags reset before move restarts.

-ru

A comma separated list of replication units.

-shard

A comma separated list of shards.

-suspend

Suspends move for the specified scope. -chunk specifies chunks to suspend, "-shard specifies that all chunk moves to/from that database will be suspended. If any chunk in scope is already in a move (any state other than "scheduled") a warning is returned indicating that move for that chunk was not suspended.

-task

A comma separated list of tasks.

-verbose

Enable verbose output mode.

Usage Notes

RESUME option is used to restart stalled task. SUSPEND is used to postpone task, and CANCEL cancels task.

CHUNK, RU or SHARD is used to filter the list of scheduled migration. Use CONFIG TASK command to retrieve the list of scheduled tasks.

Examples

Suspend all pending tasks:

GDSCTL> alter task -suspend

Delete all tasks involving (ru 3 or 4) AND (shards shard1 or shard2):

GDSCTL> alter task -cancel -ru 3,4 -shard shard1,shard2

              [-cdb sc_cdb_connstr] [-catpwd password]
              [-shard shard_list] [-async]
              [-encryption encryption][-REMOVE]

Options

Table C-19 GDSCTL config backup Options

Option Description
-rccatalog rc_connstr

A connection string to the recovery catalog database.

-target (PRIMARY|STANDBY) For shards in Data Guard configurations, database backup can be done at the primary or the standby. The default is the standby. The value for this option is either PRIMARY or STANDBY.
-destination {ALL|CATALOG| shard_list:deviceconfig:channelconfig} Definition of device types and channels for target databases. It consists of three components: shard-list, deviceconfig and channelconfig.
  • shard-list: specifies a comma separated list of shard identifiers. They can be shard space, shard group or shard names.
  • deviceconfig: configures a device type for the prefixed target databases. It must be a valid device type configuration statement for RMAN.
  • channelconfig: configures a channel for the prefixed target databases. It must be a valid channel configuration statement for RMAN.
-starttime ALL|CATALOG|shard_list:hh:mm Backup start time for individual shards and the sharded database (SDB) catalog database. It must be a local time in a day in the time zone where the target database is located and specified in 24-hour format. The smallest unit for the time is minute. For example, CATALOG:22:30 specifies that the scheduled backup for the SDB catalog database should be started at 10:30 PM. The default backup start time for a target database is the midnight (00:00). Internally the start time is converted into a UTC time before it’s passed to DBMS Scheduler to be set as the job start time
-frequency #level0_days|#level0_days:#level1_days Backup repeat intervals for incremental level 0 and level 1 backups in days. The first number is the interval for incremental level 0 backups and the second is that for level 1 backups. If a single number is specified without a following comma, it defines the interval for level 0 backups. If a comma appears in the parameter, then the number to its left is the backup interval for level 0 backups and that to its right is the interval for level 1 backups, but both numbers are optional in this case. The default intervals for level 0 and level 1 backups are respectively 7 and 1 day.
-incremental DIFFERENTIAL|CUMULATIVE Incremental level 1 backup type to either DIFFERENTIAL or CUMULATIVE. The default is DIFFERENTIAL.
-retention #recovery_window_days A recovery window for backup files. It must be a positive integer and specified in days. The default is 30 days.
-cdb sc_cdb_connstr Required if the SDB catalog database is a PDB. It specifies a connect string for the container database of the SDB catalog database.
-catpwd password Password for user GSMCATUSER. Prompted if not specified. This password only needs to be specified once for this command in an entire GDSCTL session.
-shard shard_list shard_list specifies a comma separated list of shard identifiers. They can be shard space, shard group or shard names. If the same name is used for a shard space, shard group or shard, shard space takes the highest precedence followed by shard group and then shard. There are two special words for this option: ALL and CATALOG. ALL represents the SDB catalog database and all the shards in the SDB while CATALOG represents only the SDB catalog database. The default is all shards.
-async When specified, all tasks to configure the backup for the shards will run in background. By default, the task will run in foreground. The task for the SDB catalog database will always run in foreground regardless of this flag setting.
-encryption

Encryption protocol for Advanced Network Option (ANO) used between GSM, GDSCTL and databases. OFF means that ANO is disabled. ( AES256 | AES192 | OFF).

-remov

If specified, it removes the backup configuration from the specified shards. Other provided options for the command are ignored.

Examples

The following example configures a backup channel of DISK type for the SDB catalog database, two parallel channels of DISK type for each of the shards (shard spaces dbs1 and dbs2 are used in the shard list), the backup retention window to 14 days, the level 0 and level 1 incremental backup repeat intervals to 7 and 1 day and the backup start time to 12:00 AM, leaving the incremental backup type to the default DIFFERENTIAL and the backup target type to the default STANDBY.

GDSCTL> config backup -rccatalog rcadmin/rman@inst6 -destination 
"CATALOG::configure channel device type disk format '/tmp/rman/backups/%d_%U'" -destination "dbs1,dbs2:configure device type disk parallelism 2:configure

den17b dbs1        Ok     Deployed east   ONLINE
den17c dbs2        Ok     Deployed east   READ ONLY 

The State column in the results can have the following values:

  • Created: Indicates that add shard or create shard was run, but deploy has not yet been run for that shard.

  • Replicated: Indicates that deploy was run and the Data Guard broker configuration was created. No other metadata (chunks, for example) are on the shard and the shard has not yet registered with the shard director

  • Sharded: Indicates that the database has successfully registered with the shard director. Creates chunk metadata for new shards, but does not start any automatic rebalancing. To manually get from Replicated to Sharded and beyond, run GDSCTL sync -database <shard_name>.  This is what is happening internally in this step.

  • Deployed: Indicates that all DDL catchup is completed and the shard is ready for operations. At this point, any scheduled chunk moves are begun in the background. A shard can be Deployed without having been rebalanced because rebalancing is a background operation.

config shardgroup

connect

Specifies the credentials to administer a global service management environment. Credentials must be specified to perform certain operations using GDSCTL.

Syntax

connect [user_name[/password]]@connect_identifier

Options

Table C-36 GDSCTL connect Options

Syntax Description
connect_identifier

Specify an Oracle Net connect descriptor or a net service name that maps to a connect descriptor (for example, a list of global service managers).

password

Specify the password for the specified user. If you do not specify a password, then you are prompted to enter a password. The password is obscured when entered.

user_name

Specify the name of the user to connect as. The user that you specify must have either the Global Data Services administrator or the pool administrator role. If you specify no user name, then you are prompted for a user name.

Usage Notes

You must connect to the catalog database as a user with either the Global Data Services administrator or the pool administrator privileges, depending on which command you want to run after you connect

WARNING:

Specifying a password as a connect command option is a security risk. You can avoid this risk by omitting the password, and entering it only when the system prompts for it.

Examples

Connect as the gsmadmin user to the private cloud:

GDSCTL> connect gsmadmin@mycloud
Enter password: 

Connect using a connect descriptor, without specifying a user name and password:

GDSCTL> connect (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=myhost)(PORT=1521)))
Enter username: 

copy ru

To instantiate or repair a follower member of a replication unit you can copy another follower in that replication unit from another shard.

-source

Name of the source shard.

-target

Name of the target shard .

-timeout

Timeout of connection retention between the time FAN event is sent to clients and chunk going read-only/down (seconds).

-verbose

Enable verbose mode.

Usage Notes

The source shard and target shard shouldn't be the replica leader for the given replication unit. If a member of the specified replication unit exists on the target shard, it is replaced by full replica of replication unit from the source shard.

If -source is not specified, then an existing follower of the replication unit will be chosen automatically as the source shard.

If the target database doesn't already contain a member of the specified replication unit, then the total number of replicas for the given replication unit should be below replication factor, unless -replace is specified.

If -replace is specified, the replication unit member is removed from the specified database.

Examples

GDSCTL> copy ru -ru 1 -source sh1 -target sh2

create catalog

The create catalog command is deprecated. Use create gdscatalog or create shardcatalog instead. Creates a Global Data Services catalog for global service management in a specific database.

Syntax

              [-user user_name[/password] 
              [-region region_name_list]
              [-gdspool gdspool_name_list]
              [-configname confname]
              [-autovncr {ON | OFF}]
              [-force]
              [-encryption encryption]

Options

Table C-38 GDSCTL create catalog Options

Options Description
-autovncr {ON | OFF}

This option enables (ON) or disables (OFF) autovncr mode. The default value is ON.

See the Usage Notes below for important information about this option.

-configname confname

Specify the name of the GDS configuration. The default configuration name is ORADBCLOUD.

The configuration name can be up to 32 bytes long and can contain an alphabetical character followed by zero or more alphanumeric ASCII characters, ‘_', or ‘#' and possibly separated by periods if there are multiple identifiers.

-database db_name

Specify the connect identifier for the database in which you want to create catalog.

-force

Rewrites existing global service manager configuration on catalog database.

-gdspool gdspool_name_list

Specify a comma-delimited list of database pool names. When you use this option, the specified database pools are created as part of the catalog creation. If you do not specify this option, then GDSCTL creates a default database pool named DBPOOLORA.

-region region_name_list

Specify a comma-delimited list of region names. This command creates each region and adds the regions to the catalog. If you do not specify a region, then a default region named REGIONORA is created.

-user user_name[/password]

Specify a user (and optionally, the password) that has the Global Data Services administrator privileges on the catalog database. If you do not use this option, then GDSCTL prompts you for the name and the password of a user with Global Data Services administrator privileges. If you specify a user name but not the password for the user, then GDSCTL prompts you for the password.

-encryption

Encryption protocol for Advanced Network Option (ANO) used between GSM, GDSCTL and databases. OFF means that ANO is disabled. ( AES256 | AES192 | OFF).

Usage Notes

This command is deprecated in Oracle Database 12c Release 2. Use create gdscatalog or create shardcatalog for your specific environment.

The create catalog command generates a pair of PKI public and private keys and stores them in the catalog, along with a fixed string "GSM" that is encrypted with a private key. It uses the GSMCATUSER password.

You must have the Global Data Services administrator privileges on the computer where you want to create the Global Data Services catalog.

Auto VNCR is best used in environments with simple private networks where ease of configuration is the most important consideration. To have the highest level of control over which hosts may participate in a GDS configuration, disable Auto VNCR and explicitly add the IP addresses of each database host to the VNCR configuration.

When —autovncr is enabled, Oracle attempts to find the host name of the target database when it is validated during add shard or add database execution. This host is then automatically added to the VNCR list in the catalog as an invited node. This mechanism is not compatible with all network configurations and may not work in the following cases:

  • The catalog or global service manager host does not know how to translate the host name discovered on the target database host to an real IP address. This can happen if they have different names in the hosts file or DNS on the catalog or global service manager host, or if they just do not exist on those hosts.

  • The target database host has multiple public network addresses, and Oracle chooses an address that is different than the address used when the database registers with the global service manager. This can happen if the host has multiple network cards or has configured virtual network interfaces.

  • The database is running Oracle RAC, and other Oracle RAC instances run on a different subnet. This is not a recommended configuration for Oracle RAC. Refer to the Oracle RAC documentation for recommended configurations. With Oracle RAC, Oracle Database connects to a single database host to validate the target, and returns a subnet mask that includes the entire subnet that the host is on. If other instances are on a different subnet, they have no valid VNCR entry, and registration is rejected.

When —autoVNCR is not enabled, or, if any of the above cases apply, new hosts should be added manually using add invitednode (add invitedsubnet).

Example

Create a Global Data Services catalog for global service management in the database named DB1. Also create the regions EAST and WEST, and the database pool READERFARM.

GDSCTL> create catalog -database db1 -region west,east -gdspool readerfarm

create gdscatalog

Creates a Global Data Services catalog for global service management in a specific database.

Syntax

create gdscatalog -database db_name 
                 [-user user_name[/password] 
                 [-region region_name_list]

-database db_name

Specify the connect identifier for the database in which you want to create catalog.

-force

Rewrites existing global service manager configuration on catalog database.

-gdspool gdspool_name_list

Specify a comma-delimited list of database pool names. When you use this option, the specified database pools are created as part of the catalog creation. If you do not specify this option, then GDSCTL creates a default database pool named DBPOOLORA.

-region region_name_list

Specify a comma-delimited list of region names. This command creates each region and adds the regions to the catalog. If you do not specify a region, then a default region named REGIONORA is created.

-user user_name[/password]

Specify a user (and optionally, the password) that has the Global Data Services administrator privileges on the catalog database. If you do not use this option, then GDSCTL prompts you for the name and the password of a user with Global Data Services administrator privileges. If you specify a user name but not the password for the user, then GDSCTL prompts you for the password.

-encryption

Encryption protocol for Advanced Network Option (ANO) used between GSM, GDSCTL and databases. OFF means that ANO is disabled. ( AES256 | AES192 | OFF).

-validate_network This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

The create gdscatalog command generates a pair of PKI public and private keys and stores them in the catalog, along with a fixed string "GSM" that is encrypted with a private key. It uses the GSMCATUSER password.

You must have the Global Data Services administrator privileges on the computer where you want to create the Global Data Services catalog.

Options

Table C-41 GDSCTL create shardcatalog options

Command Option Description
-agent_password password

Specify the password to be used for remote scheduler agent registration with the catalog database.

-agent_port port

Port number for XDB to use. If NULL and no current value is set, then it will default to 8080. Execute on catalog as well.

-autovncr {ON|OFF}

This option enables (ON) or disables (OFF) auto VNCR mode. The default value is ON.

See the Usage Notes below for important information about this option.

-chunks number

Specify the default number of unique chunks in a shardspace. The value of -chunks must be greater than 2 times the size of the largest shardgroup in any shardspace.

This parameter does not apply to user-defined sharding or a federated database. It will apply to all shardspaces created for composite sharding if the number of chunks is not specified in the ADD SHARDSPACE command.

All shardgroups in a shardspace have the same number of chunks. If this parameter is not specified, the default number of chunks is determined at the time of execution of the first DEPLOY command and is 120 per database of the shardgroup with the biggest number of shards

-configname config_name

Specify the name of the GDS configuration. This name is used as the virtual DB_DOMAIN of the sharded database. The default configuration name is ORADBCLOUD.

The configuration name can be up to 32 bytes long and can contain an alphabetical character followed by zero or more alphanumeric ASCII characters, ‘_', or ‘#' and possibly separated by periods if there are multiple identifiers.

-database connect_identifier

Specify the connect identifier for the database in which you want to create the catalog.

-for_federated_database

Create a catalog for a federated database.

-force

Before creating the new catalog, delete an existing shard or GDS catalog on this database.

-protectmode dg_protection_mode

Specify the Data Guard protection mode: MAXPROTECTION, MAXAVAILABILITY, or MAXPERFORMANCE (default). For Data Guard replication this parameter applies to any shardspace created without specification of protection mode in the ADD SHARDSPACE command.

-region region_name_list

Specify a comma-delimited list of region names. This command creates each region and adds the regions to the catalog. If you do not specify a region, then a default region named REGIONORA is created.

-repl DG|NATIVE

Specify the technology used to replicate data in the sharded database. Only one value can be specified for this parameter: DG for Data Guard and NATIVE for native RAFT replication. The default value is DG. This parameter cannot be modified after the catalog has been created. This parameter cannot be modified after the catalog has been created.

-sdb sdb_name

Specify the virtual DB_UNIQUE_NAME for the sharded database. The default name is ORASDB.

The sharded database (SDB) name can be up to 30 characters long and can be an alphabetical character followed by zero or more alphanumeric ASCII characters or an underscore (_).

-sharding {system | composite | user}

Specify the sharding type: SYSTEM for system-managed (default), USER for user-defined, and COMPOSITE. This parameter cannot by modified after the catalog has been created. Oracle GoldenGate does not support the user-defined sharding method.

-repunits reunits Total number of replication units (this setting only applies to native RAFT replication). By default, Oracle Sharding determines the number of replication units (RUs) in a shardspace and the number of chunks in an RU. Note that in system-managed sharding there is one shardspace named SHARDSPACEORA.
-shardspace shardspace_name_list

Specify a comma-delimited list of shardspace names. This option creates specified shardspaces and adds them to the catalog. If you do not specify a shardspace, then a default shardspace named SHARDSPACEORA is created.

—user username[/password]

Specify a user (and optionally, the password) that has the administrator privileges on the catalog database. If you do not use this option, then GDSCTL prompts you for the name and the password of a user with administrator privileges. If you specify a user name but not the password for the user, then GDSCTL prompts you for the password.

-encryption

Encryption protocol for Advanced Network Option (ANO) used between GSM, GDSCTL and databases. OFF means that ANO is disabled. ( AES256 | AES192 | OFF).

-validate_network This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

The create shardcatalog command creates a GDS catalog specifically designed for a sharded database (SDB). This command cannot be used to create a conventional GDS catalog. Execution of this command is the first step required to create an SDB. The command is executed by the user with the GDS administrator or SYSDBA privileges.

Keep the following points in mind when using create shardcatalog:

  • Only a single sharded database can be created using a shard catalog. A shard catalog cannot be used for a regular GDS configuration.

  • Any arbitrary password can be specified for remote agent registration. If one is stipulated and an agent registration password already exists, it will be overridden with the new password. In order to successfully execute the GDSCTL CREATE SHARD command, an agent password must be set using CREATE SHARDCATALOG or MODIFY CATALOG.

  • CHUNKS defines the default number of unique chunks in a shardspace. It is applied to all shardspaces created for composite sharding if the number of chunks is not specified in the ADD SHARDSPACE command.

  • This command creates each region and adds the regions to the catalog. If you do not specify a region, then a default region named REGIONORA is created.

  • The default replication factor specified by REPFACTOR can be overridden for a particular shardgroup by specifying the replication factor in the corresponding ADD SHARDGROUP command. For automatically created default shardgroups the parameter cannot be overridden. A non-default shardgroup must be created to customize the replication factor.

  • The SHARDSPACE option creates specified shardspaces and adds them to the catalog. If you do not specify a shardspace, then a default shardspace named SHARDSPACEORA is created.

  • For Data Guard replication the PROTECTMODE parameter applies to any shardspace created without specification of protection mode in the ADD SHARDSPACE command.

  • The FOR_FEDERATED_DATABASE option is mutually exclusive with the SHARDING option.

  • Auto VNCR is best used in environments with simple private networks where ease of configuration is the most important consideration. To have the highest level of control over which hosts may participate in a GDS configuration, disable Auto VNCR and explicitly add the IP addresses of each database host to the VNCR configuration.

    When -autovncr is enabled, Oracle attempts to find the host name of the target shard when it is validated during add shard execution. This host is then automatically added to the VNCR list in the catalog as an invited node. This mechanism is not compatible with all network configurations and may not work in the following cases:

    • The catalog or global service manager host does not know how to translate the host name discovered on the target shard host to an real IP address. This can happen if they have different names in the hosts file or DNS on the catalog or global service manager host, or if they just do not exist on those hosts.

    • The target shard host has multiple public network addresses, and Oracle chooses an address that is different than the address used when the shard registers with the global service manager. This can happen if the host has multiple network cards or has configured virtual network interfaces.

    • The shard is running Oracle RAC, and other Oracle RAC instances run on a different subnet. This is not a recommended configuration for Oracle RAC. Refer to the Oracle RAC documentation for recommended configurations. With Oracle RAC, Oracle Database connects to a single shard host to validate the target, and returns a subnet mask that includes the entire subnet that the host is on. If other instances are on a different subnet, they have no valid VNCR entry, and registration is rejected.

    When —autoVNCR is not enabled, or, if any of the above cases apply, new hosts should be added manually using add invitednode (add invitedsubnet).

Note: Oracle GoldenGate replication support for Oracle Sharding High Availability is deprecated in Oracle Database 21c.

Examples

The following example creates a shard catalog on the mydb database.

GDSCTL> CREATE SHARDCATALOG –DATABASE mydb

databases

Displays the status of all databases.

Syntax

{status database | databases} [-gsm gsm_name]
                              [-database db_name]
                              [-gdspool gdspool_name]

Options

Table C-42 GDSCTL databases Options

Option Description
-database db_name

Specify the name of the database on which you want to start the service. If you do not specify this option, then GDSCTL starts the services on all preferred databases.

-gdspool gdspool_name

Specify the name of the database pool in which the services you want to start are located. If not specified and there is only one gdspool with access granted to the user, it is used as the default gdspool.

-gsm gsm_name

Specify the name of a global service manager to check. If the name is not specified, then GDSCTL uses the current global service manager name for the session (specified with the GDSCTL set gsm command).

-raw

If specified, GDSCTL output is presented in a raw non-parsed format.

-support

If specified, GDSCTL output displays additional information.

-verbose

Enable verbose mode.

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

delete catalog

Deletes the specified catalog.

Syntax

delete catalog [-connect [user/[password]@]conn_str]
               [-force]

Options

Table C-44 GDSCTL delete catalog Options

Syntax Description
-connect

Specify an Oracle Net connect descriptor or a net service name that maps to a connect descriptor for the database (or shard).

If you do not use this option, then GDSCTL deletes the Global Data Services catalog that is used by the global service manager associated with the current session.

-force

Silently remove GDS metadata. No warnings are shown.

Usage Notes

You must have the Global Data Services administrator privileges on the computer where the database resides from which you want to delete the Global Data Services catalog

If -connect is not specified, the catalog that belongs to currently connected database (if any) is deleted.

Example

Delete the Global Data Services catalog located in the database named DB1.

GDSCTL> delete catalog -connect db1

deploy

Deploys the sharded database.

Syntax

deploy [-no_rebalance] [-validate_network][-timeout timeout]

Options

Table C-45 GDSCTL deploy Options

Option Description
-no_rebalance

Skip automatic chunk migration during incremental deploy.

-timeout

Timeout of connection retention between FAN is sent to clients and chunk going read-only/down (seconds).

-validate_network

This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

This command is executed after one or more shards have been added to the shard catalog. As the result of the command execution, a certain range of data is associated with a newly added database. If a database is part of a Data Guard Broker configuration, a role (primary or standby) is assigned to it. Then replication and/or migration of data to from other databases to newly deployed databases are initiated.

  • Deploy runs almost entirely in parallel, and mostly in the background, and will not deploy any shards which do not have all their counterparts in other shardgroups. All undeployed shards that can be deployed are deployed as the result of execution of this command.

  • Before configuring replication, this command cross-checks parameters of all databases included into the replication configuration. An error is returned if the cross-check finds inconsistency or ambiguity, for example, no primary shardgroup in a shardspace with Data Guard replication.

  • If a CREATE SHARD command had previously been issued, these new shards will be created during deployment and added to the shard catalog. If a shard needs to be created, DEPLOY runs a job for each database which requires a remote credential (see add credential and unresolvable-reference.html). This credential must be valid at the time of deployment.

  • The NO_REBALANCE option allows to skip automatic rebalancing of chunks across shards during incremental DEPLOY. Use the move chunk command to perform manual chunk migration.

Examples

Deploy the sharded database.

GDSCTL> deploy

modify catalog

Modifies the properties of the GDS catalog or shard catalog.

Syntax

modify catalog [-autovncr {ON | OFF}] 
               [-oldpwd oldpassword -newpwd newpassword] 
               [-pwd password -newkeys]
               [-agent_password password]
               [-agent_port port] 
               [-region region]
               [-recover]

Options

Table C-55 GDSCTL modify catalog Options

Syntax Description
-agent_password password

Specify the agent registration password in the catalog for the remote Scheduler agent.

-agent_port port

Port number for XDB to use. If it is NULL and no current value is set, then it will default to 8080. Execute on catalog as well.

-autovncr {ON | OFF}

This option enables (ON) or disables (OFF) autovncr mode. The default value is ON.

-newkeys

Generates a new PKI key pair.

-newpwd newpassword

Used along with -oldpwd, sets the GSMCATUSER password after changing it on the catalog database.

-oldpwd oldpassword

Used along with -newpwd, sets the GSMCATUSER password after changing it on the catalog database.

-pwd password

Provides the GSMCATUSER password to generate the PKI keys when using -newkeys.

-recover

Perform catalog recovery to the last consistent state.

-region region

Region that the database, catalog, shard, shardgroup, or global service manager belongs to.

Usage Notes

To use this command, there must be a least one global service manager running and a connection with the catalog database must have already been established (see the connect command).

You must connect to the catalog database as a user with the Global Data Services administrator privileges, using the connect command before running this command.

Auto VNCR is best used in environments with simple private networks where ease of configuration is the most important consideration. To have the highest level of control over which hosts may participate in a GDS configuration, disable Auto VNCR and explicitly add the IP address(es) of each database host to the VNCR configuration.

The GSMCATUSER password should be updated regularly for security reasons. Use the following command to perform this operation.

modify catalog -oldpwd oldpassword -newpwd newpassword

This command fetches the encrypted private key and encryption string, decrypts them using the old password, re-encrypts them with the new password and stores them again.

If the GSMCATUSER password is changed, you must execute MODIFY CATALOG to update catalog security scheme, with -newpwd and -oldpwd specified.

The PKI keys must be updated regularly, which is done using modify catalog -oldpwd oldpassword -newkeys. This command generates a new PKI key pair and replaces the corresponding fields in the database.

If you decide to replace the PKI keys, or just after A patchset upgrade on the catalog database, run this command:

modify catalog -pwd **  -newkeys

An arbitrary password can be stipulated for remote agent registration. If an agent registration password already exists, it will be overridden with the new password. In order to successfully execute the GDSCTL CREATE SHARD command, an agent password must be set using the CREATE SHARDCATALOG or MODIFY CATALOG command.

Examples

Turn off autovncr mode for the catalog database.

connect gsmadmin@mycloud 
GDSCTL> modify catalog -autovcnr off

Specify the remote Scheduler agent registration password.

connect gsmadmin@mycloud 
GDSCTL> modify catalog –agent_password mypass

Update catalog security scheme.

GDSCTL> modify catalog -autovncr OFF -oldpwd opwd -newpwd npwd -pwd pwd -newkeys

                  -drop_instances inst_list
                -cardinality {UNIFORM | SINGLETON}

Options

Table C-63 GDSCTL modify service Options

Option Description
-add_instances [-preferred comma-delimited-list] [-available comma-delimited-list]

Provides a list of preferred and available instances for the given service on the given database. The provided list over-rides existing assigned instances, if any. Using the –preferred and –available options is optional, but at least one of these must be provided.

-available db_name_list

Specify a comma-delimited list of available databases on which the service runs, if the preferred databases are not available.

The list of available instances must be mutually exclusive with the list of preferred instances.

If you attempt to add a preferred or available database to a service that was configured with -preferred_all, then GDSCTL returns an error.

-cardinality {UNIFORM | SINGLETON}

Specify the cardinality option for a service running on a policy-managed Oracle RAC database. Services with cardinality set to UNIFORM are offered on all database instances. Services with cardinality set to SINGLETON are offered on only one database instance.

-clbgoal {SHORT | LONG}

For connection load balancing goal: set to SHORT if using run-time load balancing, set to LONG for long running connections such as batch jobs or older SQL*Forms style.

The default value for this option is SHORT.

-commit_outcome {TRUE | FALSE}

Enable Transaction Guard; when set to TRUE, the commit outcome for a transaction is accessible after the transaction's session fails due to a recoverable outage.

-database db_name

Specify the name of the database on which you want to modify the service.

When -database is specified, you must specify exactly one of:

  • -server_pool and/or -cardinality. Either is optional, but at least one must appear, both can be used at once.

  • -add_instances, -modify_instances, or -drop_instances. Exactly one of these three options must be used.

-dtp {TRUE | FALSE}

Indicates whether Distributed Transaction Processing should be enabled for this service. This ensures that the service is offered at exactly one instance at a time for XA affinity.

-drop_instances inst_list

Provide a list of instances to be removed from the existing assigned instances for a given service on a given database. The provided list of instances will be removed from the existing assigned list.

-edition edition_name

Specify the initial session edition of the service.

When an edition is specified for a service, all subsequent connections that specify the service use this edition as the initial session edition. However, if a session connection specifies a different edition, then the edition specified in the session connection is used for the initial session edition.

GDSCTL does not validate the specified edition name. During connection, the connect user must have USE privilege on the specified edition. If the edition does not exist or if the connect user does not have USE privilege on the specified edition, then an error is raised.

-failover_primary

If you set the -role option to PHYSICAL_STANDBY, then you can use this option to enable the service for failover to the primary database.

-failoverdelay failover_delay

For Application Continuity and TAF, the time delay (in seconds) between reconnect attempts for each incident at failover.

-failovermethod {NONE | BASIC}

TAF failover method (for backward compatibility only).

If failovertype is set to either SESSION or SELECT, then choose BASIC for this option.

-failoverretry failover_retries

For Application Continuity and TAF, the number of attempts to connect after an incident.

-failovertype {NONE | SESSION | SELECT | TRANSACTION}

Specify the failover type.

To enable Application Continuity for Java, set this parameter to TRANSACTION. To enable Transparent Application Failover (TAF) for OCI, set this parameter to SELECT or SESSION.

-force

If you use this option, then all sessions are disconnected when the service is moved, requiring the sessions using the service to reconnect (potentially to a different instance).

If you do not use this option, then the sessions that are connected to a database using this service stay connected, but all new sessions cannot be established to the service.

-gdspool gdspool_name

Specify the name of the database pool to which the service belongs. If not specified and there is only one gdspool with access granted to user, it is used as the default gdspool.

-lag {lag_value | ANY}

Specify the lag for the service in seconds. You can use the keyword ANY to indicate that there is no upper threshold on the lag time.

The default value for the -lag option is ANY.

-locality {ANYWHERE | LOCAL_ONLY}

The service region locality. If you do not use this option, then the default value of ANYWHERE is used for the service.

-modifyconfig

Use this option to indicate that you are changing the current list of preferred and available databases for the service. If you use this option, then any databases that are not specified in either the preferred or available list, but were previously assigned, are removed from the list of databases on which the service can run.

-modify_instances [-preferred comma-delimited-list] [-available comma-delimited-list]

The provided comma-delimited-list of preferred and available instances is merged with the existing list currently stored in the catalog.

If you specify an instance in the comma-delimited-list that is not already in the stored list, it is added to the stored list in its correct mode (preferred or available.)

If you specify in comma-delimited-list an instance that is already in the stored list, then the mode of the instance in the stored list is modified to the provided mode (preferred or available). If the user provided mode is the same as the stored mode, then the mode of the instance will not be changed.

Any instances already in the stored list that are not in the provided list remain unchanged in the stored list.

Note that an instance cannot be both preferred and available, it can be in one mode only.

–preferred and –available are optional but at least one list must be provided.

-new_db database_name

Specify the name of the new database on which the service runs.

If you attempt to move a service that was configured with -preferred_all, then GDSCTL returns an error.

-notification {TRUE | FALSE}

Enable Fast Application Notification (FAN) for OCI connections.

-old_db database_name

Specify the name of the old database on which the service runs.

If you attempt to move a service that was configured with -preferred_all, then GDSCTL returns an error.

-policy {AUTOMATIC | MANUAL}

Specify the management policy for the service.

If you specify AUTOMATIC (the default), then the service automatically starts when the database restarts, either by a planned restart or after a failure. Automatic restart is also subject to the service role.

If you specify MANUAL, then the service is never automatically restarted upon planned restart of the database. A MANUAL setting does not prevent the global service manager from monitoring the service when it is running and restarting it if a failure occurs.

-pdbname pdb_name

Specify the pluggable database name.

-preferred db_name_list

Specify a comma-delimited list of preferred databases on which the service runs. When changing a database from available to preferred, you do not specify a value for the -preferred option.

The list of preferred instances must be mutually exclusive with the list of available instances.

If you attempt to add a preferred or available database to a service that was configured with -preferred_all, then GDSCTL returns an error.

-preferred_all

Specifies that all the databases in the database pool are preferred databases. Any new databases added to the pool are configured as preferred databases for this service.

This option cannot be used with the -preferred and -available options.

-region_failover

Indicates that the service is enabled for region failover. You can only use this option when you specify LOCAL_ONLY for the -locality option.

-replay_init_time replay_init_time

For Application Continuity, this parameter specifies the time (in seconds) after which replay is not initiated. Default value is 300 seconds.

-retention retention_seconds

For Transaction Guard (commit_outcome set to TRUE), this parameter determines the amount of time (in seconds) that the commit outcome is retained in the database.

-rlbgoal {SERVICE_TIME | THROUGHPUT}

Run-time Load Balancing Goal. Set this parameter to SERVICE_TIME to balance connections by response time. Set this parameter to THROUGHPUT to balance connections by throughput.

If you do not use this option, then the value defaults to SERVICE_TIME for the run-time load balancing goal.

-role {[PRIMARY] | [PHYSICAL_STANDBY] [-failover_primary] | [LOGICAL_STANDBY] | [SNAPSHOT_STANDBY]}

Specify the database role that the database must be for this service to start on that database. This applies only to database pools that contain an Oracle Data Guard broker configuration.

See Also: Oracle Data Guard Concepts and Administration for more information about database roles

-server_pool server_pool_name

Specify the name of the Oracle RAC server pool in the GDS pool database to which the service belongs (for a policy-managed Oracle RAC database).

-service service_name

Specify the name of the global service.

-session_state {DYNAMIC | STATIC}

For Application Continuity, this parameter specifies whether the session state that is not transactional is changed by the application. A value of DYNAMIC is recommended for most applications.

-sql_translation_profile stp_name

Use this option to specify a SQL translation profile for a service that you are adding after you have migrated applications from a non-Oracle database to an Oracle database.

This option corresponds to the SQL translation profile parameter in the DBMS_SERVICE service attribute.

Notes:

  • Before using the SQL translation feature, you must migrate all server-side application objects and data to the Oracle database.

  • Use the config service command to display the SQL translation profile.

See Also: Oracle Database SQL Translation and Migration Guide for more information about SQL translation

-table_familyfamily

Specifies the table family name as a property of the service. This parameter takes one of the table family values (root table schema.name) as shown in the CONFIG TABLE FAMILY output.

If the schema name or the table name is case-sensitive, use two-level quotes (single quotes outside, double quotes inside) around the whole string, for example, '"TESTUSER1.Customers6"'. No quotes are needed if neither name is case sensitive.

-tafpolicy {BASIC | NONE }

TAF policy specification (for administrator-managed databases only).

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the connect command before running this command.

Use this command to:

  • Add databases to the preferred or available lists for the service

  • Move a service from one database to another database

  • Change an available database to a preferred database or a preferred database to an available database

  • Modify the high availability attributes of the service

If you want to temporarily move a service from one database to a different database, then use the relocate service command.

Examples

Add the database DB3 as a preferred database for the service G_SALES_REPORT in the database pool MYREADERFARM.

GDSCTL> modify service -gdspool myreaderfarm -service g_sales_report -preferred db3

Modify the service G_DAILY_SALES_REPT in the database pool MYREADERFARM to change the run-time load balancing goal to THROUGHPUT.

GDSCTL> modify service -gdspool myreaderfarm -service g_daily_sales_rept
  -rlbgoal THROUGHPUT

Move the service G_SALES_REPORT in the database pool MYREADERFARM from the database DB1 to DB4.

GDSCTL> modify service -gdspool myreaderfarm -service g_sales_report
  -old_db db1 -new_db db4

Upgrade the DB3 database from an available database to a preferred database for the service G_SALES_REPORT in the database pool READFARM.

GDSCTL> modify service -gdspool readfarm -service g_sales_report
  -available db3 -preferred

Assume the service G_SALES_REPORT currently has the databases DB1 and DB2 assigned as preferred databases, and the database DB3 assigned as an available database. Exchange the preferred and available databases DB1 and DB3, and remove the DB2 database for the service SALES_REPORT in the database pool READFARM.

GDSCTL> modify service -gdspool readfarm -service g_sales_report -modifyconfig
  -available db3 -preferred db1

Modify the properties of the service G_SALES_REPORT in the database pool READFARM to specify that it should run only in the server pool named SALESPOOL for the policy-managed Oracle RAC database DB1.

GDSCTL> modify service -gdspool readfarm -service g_sales_report -database db1
-server_pool salespool

Supply the preferred and available instances for the given service on the given database.

GDSCTL> modify service –gdspool mypool –service mysvc –database mydb –add_instances
 –preferred inst1,inst2 –available inst3,inst4

In a system-managed sharded database, the table family ID parameter is specified as a property of the service.

GDSCTL> modify service –GDSPOOL shdpool –table_family sales.customer -service sales

It doesn't apply to user-defined sharding or a federated database since there are no shardgroups in this case.

-repunits

Total number of replication units (SNR only).

Usage Notes

The number of chunks can only be modified if a shardspace does not contain deployed shards. This command is not applicable to a federated database.

Examples

Modify the GOLD shardspace to have 6000 chunks.

GDSCTL> modify shardspace –shardspace gold –chunks 6000  

move chunk

Moves a listed set of chunks from one shard to another shard or multiple shards.

Syntax

move chunk -chunk {chunk_id_list | ALL}
           -source shard_name
          [-target shard_name]
          [-timeout]
          [-verbose]
          [-copy]

Options

Table C-67 GDSCTL move chunk Options

Option Description
-chunk {chunk_id_list | ALL}

Specify a comma-separated list of chunk IDs.

If -chunk ALL is specified without the -target option, all of the chunks are removed from the source shard and distributed to all of the remaining shards in a round-robin manner.

Usage Notes

Chunks cannot be moved between shards that belong to different shardgroups.

If -chunk ALL is specified without the -target option, all of the chunks are removed from the source shard and distributed to all of the remaining shards in a round-robin manner.

Examples

Move chunks 3 and 4 from SALE1 to SALE3.

GDSCTL> move chunk -chunk 3,4 –source sale1 –target sale3  

Move all chunks from sale1 and distribute evenly among the remaining shards.

GDSCTL> move chunk -chunk ALL -source sale1

move ru

Move a member replica of a replication unit from one shard to another.

Syntax

[ru|replication_unit] -ru ru_id -source source_db 
         -target target_db

Options

Table C-68 GDSCTL move ru Options

Option Description
-force

Allow operation to bypass RAFT replication role checks.

-ru

Replication unit ID

-source

Name of the source shard.

-target

Name of the target shard.

recover shard

Executes all DDL statements on the specified shard (database), starting from the one that was previously executed with errors. The command is intended to perform all skipped DDL changes after database administrator fixes shard issues.

Syntax

recover shard -gdspool pool
              -shard shard_name
             [-skip_first|-ignore_first]
             [-full]

Options

Table C-69 GDSCTL recover shard Options

Option Description
-full

Full recovery mode.

-gdspool pool

Specify the GDS pool. If not specified and there is only one GDS pool with access granted to user, it will be used by default.

-ignore_first

Make first failed DDL statement obsolete.

-shard shard_name

The name of the shard.

-skip_first

Skip the first failed DDL statement.

Usage Notes

Use SKIP_FIRST to skip first DDL. This is typically required after manual fix done by database administrator. For example, if CREATE TABLE statement fails because of a lack of space, the database administrator fixes the issue and re-executes CREATE TABLE. To avoid ORA-39151 (table exists) in RECOVER SHARD the database administrator must specify -SKIP_FIRST.

Use IGNORE_FIRST to mark the first DDL as obsolete. This is required when the wrong DDL statement was specified and failed on all shards. In this case, you need to mark it down as obsolete. FULL mode performs a complete recovery, including DDL operations, failed chunk migration, tablespace sets reconstruction, and database parameters.

Examples

Recover shard shd1.

GDSCTL> recover shard -shard shd1

relocate chunk

This command moves a list of chunks in all the replicas of the specified source RU to all the replicas in the target ru.

-sourceru

Source replication unit ID

-targetru

Target replication unit ID

-timeout

Timeout of connection retention between FAN is sent to clients and chunk going read-only/down (seconds).

-verbose

Enable verbose mode

Usage Notes

The source and target replication unit must be colocated in the same shard. leaders on the same shard and followers on the same shards. if not use SWITCHOVER to move the leader and MOVE RU to move the followers to colocated shards.

The specified chunks must be in the same source replication unit. If target ru is not specified, an empty target replication unit will be created.

Examples

GDSCTL> relocate chunk -chunk 3,4 -sourceru  1 -targetru 2

relocate service

Stops a service on one database and starts the service on a different database.

Syntax

                  -new_db db_name
                 [-force]
                 [-override [-oldpwd oldpassword] [-newpwd newpassword]]

Options

Table C-71 GDSCTL relocate service Options

Option Description
-force

If you use this option, then all sessions are disconnected when the service is moved, requiring the sessions using the service to reconnect (potentially to a different instance).

If you do not use this option, then the sessions that are connected to a database using this service stay connected, but new sessions cannot be established to the service.

-gdspool gdspool_name

Specify the name of the database pool where the service is located. If not specified and there is only one gdspool with access granted to user, it is used as the default gdspool.

-new_db db_name

Specify the name of the database to which you want to move the service.

-newpwd newpassword

Specify the password for the GSMUSER in the database to which the service is being relocated (the target database).

-old_db db_name

Specify the name of the database where the service is currently located.

-oldpwd oldpassword

Specify the password for the GSMUSER in the source database, or the database where the service is currently located.

-override

This option causes the command to execute without updating the global service manager catalog. You can use this option when the catalog database is unavailable.

During normal operation, you should not use this option.

-service service_name

Specify the name of the global service you are relocating.

Usage Notes

Unlike using the modify service command to change the location of a service, this command does not change the underlying configuration. This command temporarily relocates a service to run on another database.

If -force is not specified, then the global service must have been started on the old database and not running on the new database prior to command execution. If -force is not specified, then sessions already connected to this global service stay connected, but new sessions cannot be established.

If -override is specified the command will be executed without going to the GDS catalog. Use this option when the GDS catalog is unavailable. It is not recommended for use under normal operation.

If you attempt to use this command on a service that was previously configured with the -preferred_all option, then GDSCTL returns an error.

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command

Example

Relocate the service SALES_REPORT in the READFARM database pool from the DB2 database to the DB3 database.

GDSCTL> relocate service -gdspool readfarm -service sales_report -old_db db1
 -new_db db3

remove brokerconfig

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

If a GDS pool does not contain a Data Guard Broker configuration, an error is returned.

Example

Remove the Oracle Data Guard broker configuration from the database pool MYDGPOOL.

GDSCTL> remove brokerconfig -gdspool myreaderfarm

remove cdb

Options

Table C-73 GDSCTL remove cdb Options

Option Description
-cdb {cdb_name_list | ALL}

Specify a comma-delimited list of CDB names to remove, or specify ALL to remove all CDBs from the catalog.

-force

Remove one or more specified CDBs, even if they are inaccessible and/or contain PDB shards which may contain chunks. It might result in a lower number of replicas or total unavailability for a certain range of data.

WARNING:

No chunks are moved before removing the CDB which may result in data loss.

WARNING:

Forced removal of a CDB will also cause the removal of all CDBs that are replicas of the CDB being forcibly removed.

Examples

Remove the cdb named cdb1.

GDSCTL> remove cdb -cdb cdb1

Options

Table C-75 GDSCTL remove database Options

Option Description
-all

Removes all databases in the database pool.

-database db_name_list

Specify a comma-delimited list of database names that you want to remove from the database pool.

You cannot specify a database that was added through an Oracle Data Guard broker configuration; you must use Oracle Data Guard to remove these databases.

-gdspool gdspool_name

Specify the GDS pool name. If not specified, and there is only one GDS pool with access granted to the user, it will be used by default.

-force

Removes the database from the catalog even if the database is not available.

Using this option can result in global services not being removed from the database.

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

If a pool already contains a Data Guard Broker configuration, an error is returned because a database must be removed through DGMGRL in this case.

With Oracle Globally Distributed Database, only an undeployed database can be removed. If a database is offline or inaccessible, it has to be first undeployed with the -force option and then removed with the -force option.

resume services

Resumes global service activity and traffic routing to the database, previously blocked by SUSPEND SERVICES command.

Syntax

GDSCTL> RESUME SERVICES -DATABASE target_db

Options

Table C-87 GDSCTL resume services Options

Option Description
target_db

Specify the name of the database

Example

Resumes global service activity and traffic routing to the database:

GDSCTL> RESUME SERVICES -DATABASE dba
 
GDSCTL>

rman

Allow users to submit RMAN commands to a list of shards for execution.

Syntax

rman -shard shard_list [-check_syntax] [-from_cdb userid[/password]] 
[-catpwd password] [-async] (-cmd_file cmdfile | <quote>rman-stmts<quote>)

Options

Table C-88 GDSCTL rman Options

Option Description
-shard

Specifies a comma-delimited list of shard identifiers. Each shard identifier can be a region, shardspace, shardgroup or shard name. If the same name is used for a region, shardspace, shardgroup or shard, region takes the highest precedence followed by shardspace, shardgroup and then shard. For example, assume a sharded database has a shardspace and a shard both named "foo". When name "foo" is provided in the specified shard list, it is considered a shardspace and expanded to a list of the shards in the shardspace "foo". Two special words can be used for shard list: ALL and CATALOG. "ALL" means the sharded database catalog database and all the shards in the database while "CATALOG" means only the catalog database. For commands where this parameter is optional, if this value is not specified the value defaults to "ALL".

-check_syntax

If specified, it only checks syntax for the input RMAN commands.

-from_cdb

This option provides a CDB common user and a password in the form of "user/password". When this option is used, the provided RMAN commands will be run from the shard root container. The provided user must have SYSBACKUP privilege.

-catpwd

The GSMCATUSER password

-cmd_file

RMAN command file path

Usage Notes

RMAN commands can be supplied either with a command file or directly in the command line. The syntax of the commands is the same as when they are entered at the RMAN prompt.

When the comamnds are supplied in the command line, they must be put in quotation marks. If the commands themselves contain single quotes, then double quotes should be used for the commands.

Some RMAN commands can only be executed from CDB root. If such a command is supplied, option -FROM_CDB must be used. Commands that should be executed from the shard PDBs and those that should be executed from shard CDB root cannot be supplied at the same time.

Some RMAN commands cannot be used inside command files, for example, HOST. These commands cannot be used here in the command line or through a command file.

Example

The command allows users to run various RMAN commands against the selected shards. The following example reports the objects needed to be backed up in the shards in shard group DBS1. Assuming that the shard PDB name is PDB1 for all the shards in shard group DBS1:

GDSCTL> rman -shard dbs1 -from_cdb 'report need backup of pluggable database pdb1;';

Assuming that datafile 1 for shard SHARD1 needs to be backed up. The example below shows how to back up the datafile for shard SHARD1:

GDSCTL> rman -shard shard1 -from_cdb 'backup datafile 1;';

run backup

Run Sharded Database (SDB) Backup Jobs.

Syntax

run backup [-tag tag] [-catpwd password] [-shard shard_list] [-async]

Options

Table C-89 GDSCTL run backup Options

Syntax Description
-tag tag

A name for the backup. If not provided, a unique tag is automatically generated for the backup. The size limit for tag is 30.

-catpwd password

Password for user GSMCATUSER. Prompted if not specified. It needs to be specified once for the entire GDSCTL session.

-shard shard_list

shard_list is a comma separated list of shard identifiers. They can be shard space, shard group or shard names. The default is no shards

-async When specified, all tasks to configure the backup for the shards will run in background. By default, the task will run in foreground.

Examples

In the following example, a backup for the shards in shard space dbs1 is created before a shard maintenance.

GDSCTL> run backup -tag backup_before_db_maintenance -shard dbs1 -catpwd gsm

set dataguard_property

Dynamically updates the value of a specified property of a broker configuration or database.

Syntax

set dataguard_property {-shardspace name | -brokerconfig name | -shard name |   
 -shardgroup name} [-reset] [-scope { configuration | database}]                 
 'property_name'=property_value

Options

Table C-91 GDSCTL set dataguard_property Options

Syntax Description
-shardspace name

The name of the shardspace.

-brokerconfig name

Broker configuration identifier.

-shard name

The name of the shard.

-shardgroup name

The name of the shardgroup.

-reset

Resets property to default value.

-scope

Defines the scope for property: database or broker configuration.

Usage Notes

A database property of a member of a Data Guard Broker configuration can be updated by using the -SHARD option. The -SHARDGROUP option allows users to update a database property of all databases in a specified shardgroup.

A property of the entire Data Guard Broker configuration can be updated by using the -BROKERCONFIG or -SHARDSPACE option.

See Oracle Data Guard Broker guide for the complete list of the Broker configuration and database properties.

If none of -shardspace/-shardgroup/-shard/-brokerconfig is specified, then the command will act on all broker configs or databases in the catalog.

If the user specifies -shardspace, then the command will only act on the broker configs / shards in that shardspace. Likewise with -shard and -shardgroup.

Specifying -scope configuration will override the default scope of 'database' for -shard and -shardgroup. Likewise, specifying -scope database will override the default scope of 'configuration' for -shardspace and -brokerconfig

Example

GDSCTL> set dataguard_property -shard db32 'archivelagtarget'=1200

sql

Executes a SQL statement or a PL/SQL stored procedure against a sharded database.

Syntax

sql "sql_statement"

Options

Table C-100 GDSCTL sql Options

Option Description
sql_statement

Enter the SQL statement or PL/SQL stored procedure to be executed. Do not include a semi-colon (;) after the SQL statement to be executed.

Usage Notes

This command can only be executed against a sharded GDS pool. The statements are executed in the GDS catalog database and are then broadcast to all shards in the pool. Since there can be only one sharded pool in a GDS configuration, all SQL statements executed on the catalog database are applied to this pool, if it exists.

Database objects created by this command in the catalog database are used as a schema of the sharded database and are not intended to store user data. The only exception is tables duplicated on all shards (reference tables) – they are populated with data in the catalog database.

SELECT statements are not allowed as the parameter.

The SQL statement or PL/SQL stored procedure to be executed must be enclosed in double quotation marks.

If the string that GDSCTL passes to PL/SQL contains a filename, then the filename must be enclosed in single quotation marks.

Do not include a semi-colon (;) after the SQL statement to be executed.

Examples

Using the gdsctl sql command.

GDSCTL> sql “CREATE TABLESPACE SET ts1 IN SHARDGROUP sgr1"

start gsm

-validate_network

This flag enables several network validation checks, including checking network connectivity between hosts and checking VNCR entries are valid.

Usage Notes

  • You must run GDSCTL on the same host where the global service manager you want to start is located.

  • You must have operating system privileges on the computer where you want to start the global service manager to run this command.

Example

Start the global service manager gsm1 on the local host.

GDSCTL> start gsm -gsm gsm1

Options

Table C-102 GDSCTL start observer Options

Option Description
-database db_name

The name of the database.

-timeout seconds

The global service manager requests timeout in seconds.

Usage Notes

TIMEOUT (default 15) represents the time between when the shard director/global service manager receives requests and starts the observer. See Oracle Globally Distributed Database Guide for the automatic rules for choosing the right region for the shard director (global service manager) server to start the observer. If shard director servers are not running in this region, the observer is not started.

Example

GDSCTL> start observer -database mydb

                 -override [-pwd password] -connect connect_identifier}]

Options

Table C-104 GDSCTL start service Options

Option Description
-database db_name

Specify the name of the database on which you want to start the service. If you do not specify this option, then GDSCTL starts the services on all preferred databases.

-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor.

-gdspool gdspool_name

Specify the name of the database pool in which the services that you want to start are located. If not specified and there is only one gdspool with access granted to the user, it is used as the default gdspool.

-override

This option causes the command to run without updating the global service manager catalog. You can use this option when the catalog database is unavailable.

During normal operation, you should not use this option.

-pwd password

Specify the password of the GSMUSER in the specified database.

-service service_name

Specify a comma-delimited list of global service names. If you do not use this option, then GDSCTL starts all the services in the database pool.

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

Before starting services which run on administrator-managed databases, they must be modified for those databases to stipulate which instances should run the service. Please refer to the -modify_instances parameter of the modify service command.

Read the specified RMAN log from the specified shard and display it in the console or save it into the file specified with the option -OUTPUT_LOG. The RMAN log name usually comes from the output of this command when it is run without the option -READ_LOG.

Examples

The following example shows the job state and all job run details from the sharded database (SDB) catalog and the primary shard rdbmsb_cdb2_pdb1.

GDSCTL> status backup -catpwd -shard catalog,rdbmsb_cdb2_pdb1;

status database

Displays the runtime status of databases, such as registration information, services, and so on.

Syntax

{status database | databases} [-gsm gsm_name]
                              [-database db_name]
                              [-gdspool gdspool_name]
                              [-raw | -support | -verbose] 

Options

Table C-107 GDSCTL status database Options

Option Description
-database db_name

Specify the name of the database on which to check status

-gdspool gdspool_name

Specify the name of the database pool. If not specified and there is only one gdspool with access granted to the user, it is used as the default gdspool.

-gsm gsm_name

Specify the name of a global service manager to check. If the name is not specified, then GDSCTL uses the current global service manager name for the session (specified with the GDSCTL set gsm command).

-raw

If specified, GDSCTL output is presented in a raw, non-parsed format.

-support

If specified, GDSCTL output displays additional support information.

-verbose

Enable verbose output mode.

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

This command requires a locally started global service manager. If -gsm is not specified for STATUS DATABASE, then the currently connected global service manager name is used by default.

Example

Display the status of all databases:

GDSCTL> status database

The gdsctl status database command returns output similar to the following:

Database: "dbcat1" Registered: Y State: Ok ONS: N. Role: PRIMARY Instances: 1
 Region: east
   
   Service: "sales_svc2" Globally started: N Started: N
            Scan: Y Enabled: Y Preferred: Y
   Service: "sales_svc1" Globally started: Y Started: Y
            Scan: N Enabled: Y Preferred: Y
   Registered instances:

status service

Displays the status of a specific service.

Syntax

{status service | services} [-gsm gsm_name]
                            [-service service_name]
                            [{-raw|-verbose|-support}]

Options

Table C-111 GDSCTL status service Options

Option Description
-gsm gsm_name

Specify the name of a global service manager. If the name is not specified, then GDSCTL uses the current global service manager name for the session (specified with the GDSCTL set gsm command).

-raw

Used by oracle internal components.

-service service_name

Specify a comma-delimited list of global service names. If you do not specify any services, then GDSCTL displays the status of all services in the database pool.

-support

Display more detailed information concerning load balancing.

-verbose

Display extra information related to load balancing.

Usage Notes

  • You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

  • This command is similar to services.

Example

Display the status of service sales_report1.sales.oradbcloud:

GDSCTL> status service -service sales_report1.sales.oradbcloud

The gdsctl status service command returns output similar to the following:

Service "sales_report1.sales.oradbcloud" has 3 instance(s). Affinity: ANYWHERE
   Instance "sales%1", name: "dbcat2", db: "dbcat2", region: "east",
 status: ready.
   Instance "sales%11", name: "dbcat1", db: "dbcat1", region: "west",
 status: ready.
   Instance "sales%31", name: "dbcat3", db: "dbcat3", region: "east",
 status: ready.

stop gsm

Stops a specific global service manager.

Syntax

stop gsm [-gsm gsm_name]

Options

Table C-112 GDSCTL stop gsm Options

Option Description
-gsm gsm_name

Specify the name of a global service manager you want to stop. If you do not specify a specific global service manager, then GDSCTL uses the current global service manager name for the session (specified with the command set gsm).

Usage Notes

  • You must run GDSCTL on the same host where the global service manager that you want to stop is located.

  • You must have operating system privileges on the computer where you want to start the global service manager to run this command.

Example

Stop the global service manager gsm1 on the local host.

GDSCTL> stop gsm -gsm gsm1

stop ru

Add a shard to the shard catalog.

Syntax

stop ru -ru ru_id [-database db]         

Options

Table C-113 GDSCTL stop ru Options

Option Description
-database

The name of the database.

-pwd password

Replication unit ID

Usage Notes

If the database is not specified, the start ru command runs on all available replicas of the specified replication unit.

Examples

GDSCTL> stop ru -ru 1 -database mydb1

stop service

Stops the specified global services.

Syntax

stop service [-gdspool gdspool_name]
             [-service service_name_list]
             [{-database db_name |
                 -override -connect connect_identifier [-pwd password]}]
             [-force]
             [-drain_timeout time]
             [-stop_option {NONE|IMMEDIATE|TRANSACTIONAL}]

Options

Table C-114 GDSCTL stop service Options

Option Description
-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for the database (or shard).

-database db_name

Specify the name of the database on which you want to stop the service. If you do not specify this option, then GDSCTL stops the services on all databases on which the service is currently running.

—drain_timeout

Set drain time in seconds.

-force

If you use this option, then GDSCTL disconnects all sessions when the service is stopped, requiring the sessions using the service to reconnect (potentially to a different instance).

If you do not use this option, then the sessions that are connected to a database using this service remain connected, but new sessions cannot be established to the service.

-gdspool gdspool_name

Specify the name of the GDS pool in which the service that you want to stop is located. If not specified and there is only one GDS pool with access granted to user, that GDS pool is used as the default GDS pool.

-override

This option causes the command to execute without updating the global service manager catalog. You can use this option when the catalog database is unavailable.

During normal operation, you should not use this option.

-pwd password

Specify the password of the GSMUSER in the specified database.

-service service_name

Specify a comma-delimited list of global service names you want to stop. If you do not use this option, then GDSCTL stops all the services in the database pool.

—stop_option

Set the default stop option to NONE, IMMEDIATE, or TRANSACTIONAL

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

If -service is not specified, all global services of GDS pool are stopped.

If -database is not specified, the global services are stopped on all of the databases.

If -force is specified, all sessions are disconnected, requiring the session using the global service to reconnect (potentially to another instance). If -force is not specified, then sessions already connected to this global service stay connected, but new sessions cannot be established to the global service.

If -override is specified, the command is executed without connecting to the GDS catalog. Use this option when the GDS catalog is unavailable. It is not recommended for use under normal operation.

Example

Stop the service SALES_REPORT, on all databases in the database pool READERFARM.

GDSCTL> stop service -gdspool readerfarm -service sales_report

suspend services

This command allows users to block database on all GSM listeners.

Syntax

This command allows users to block database on all GSM listeners. The purpose of this command is to isolate database that runs global services, but can not be accessed by applications.

GDSCTL> suspend services -database target_db 

Options

Table C-115 GDSCTL suspend services Options

Option Description
target_db

Specify the name of the database

Example

In this scenario GSM won't be able to do failover, hence we need to block this database from GSM to initiate failover and guarantee that traffic won't be redirected to this database.

GDSCTL> suspend services -database target_db db1
 
GDSCTL>

switchover ru

Switch leadership for the given replication unit to the specified database.

Syntax

switchover [ru|replication_unit] {-ru ru_id -database target_db | -rebalance}
[-timeout time]
         

Options

Table C-116 GDSCTL switchover ru Options

Option Description
-database

The name of the database.

-rebalance

Perform rebalancing of replication units across shards.

-ru

Replication unit ID

-timeout

Timeout of connection retention between FAN is sent to clients and chunk going read-only/down (seconds).

Usage Notes

If the REBALANCE option is specified, an operation of rebalancing replication units and leadership responsibilities is distributed equally across the shards.

Examples

GDSCTL> switchover ru -ru 1 -database dba

sync brokerconfig (synchronize brokerconfig)

Synchronizes the Oracle Data Guard broker configuration in the global service manager with the configuration in the database pool. The synchronize brokerconfig command has the same options and usage.

Syntax

sync[hronize] brokerconfig [-gdspool gdspool_name]
                           [-database db_name]

Options

Table C-117 GDSCTL sync brokerconfig Options

Option Description
-database db_name

Specify the name of a database in the database pool to use as a referential database, from which the configuration is queried.

If you do not use this option, then GDSCTL uses the primary database as the referential database. If a primary database does not exist in the Oracle Data Guard broker configuration, then GDSCTL uses a random database from the pool as the referential database.

-gdspool gdspool_name

Specify the database pool to which the Oracle Data Guard broker configuration belongs. If not specified and there is only one gdspool with access granted to user, that gdspool is used as the default gdspool.

If the specified database pool does not contain an Oracle Data Guard broker configuration, then GDSCTL returns an error.

Usage Notes

You must connect to the catalog database as a user with the pool administrator privileges, using the command connect before running this command.

Example

Synchronize the Oracle Data Guard broker configuration in the database pool MYREADERFARM with the configuration stored in the Global Data Services catalog.

GDSCTL> sync brokerconfig -gdspool myreaderfarm

sync database (synchronize database)

Synchronizes attributes of global services and GDS related parameters of a GDS pool database with the contents of the GDS catalog. The synchronize database command has the same options and usage.

Syntax

sync[hronize] database [-gdspool gdspool_name]
                       [-database database_name]

Options

Table C-118 GDSCTL sync database Options

Option Description
-database database_name

Specify the name of a database in the database pool to use as a referential database, from which the configuration is queried.

-gdspool gdspool_name

Specify the GDS pool to which the database belongs. If not specified and there is only one GDS pool with access granted to user, it is used as the default GDS pool.

Usage Notes

  • If database has no GDS region assigned, an error is returned.

  • If a GDS pool is specified and the database option is not specified, then each database in the pool is synchronized.

Example

Synchronize a database in the default database pool with the database mydb.

GDSCTL> sync database -database mydb

sync ru

Synchronizes data of the specified replication unit on all shards, erases RAFT logs, and resets log index and term.

Syntax

sync[hronize] ru -ru ru_id [-database db]

Options

Table C-119 GDSCTL sync ru Options

Option Description
-connect connect_identifier

Specify an Oracle Net connect descriptor or net service name that resolves to a connect descriptor for the database being added as the shard.

-pwd password

Enter the GSMUSER password. If not specified, the user is prompted for the password.

Usage Notes

If a database is not specified for the SYNC RU command, a replica to synchronize with will be chosen based on the following criteria:
  1. Pick the replica that was the the last leader.
  2. If not available, pick the replica with greatest apply index.

Examples

GDSCTL> sync ru -ru 1 -database mydb1

sync schema (synchronize schema)

Allows common shared schemas across the existing databases to be retrieved. The command compares the schemas on all of the databases and retrieves those that are common.

Syntax

sync[hronize] schema [-schema schemalist [-retrieve_only] [-restart [-force]] | -apply [-skip_first] | -show [[-ddl ddlnum] [-count n] | [-failed_only]]]

Options

Table C-120 GDSCTL sync schema Options

Option Description
-apply

Specifies that the previously retrieved DDLs should be run in the catalog.

-count n

Specifies the maximum number of entries to show.

-ddl ddlnum

Specifies the DDL numeric identifier.

-failed_only

Shows only errored out statements.

-force

Forces sync without user confirmation.

-restart

Sync from the beginning, erasing schemas synced earlier.

-retrieve_only

Specifies that the DDLs of the common schemas should be retrieved only from the databases and stored in the catalog but not applied.

-schema schemalist

Specifies that only the listed schemas will be retrieved. Specify all to include all non-Oracle schemas.

-show

Shows DDL statements and their execution status.

-skip_first

Specifies that the first failed DDL statement is skipped.

Usage Notes

This command is used only when the catalog is created for a federated database, which can be created by using option -for_federated_database of the create shardcatalog command. This option is mutually exclusive with –sharding parameter. The rest of the steps are similar to sharded database environment setup with user-defined sharding [create shardcatalog, add gsm, add shardspace, add shard, deploy]. After deployment is complete, the sync schema command can be run to import specified schemas from shards to the catalog.
The sync ddl command combines two operations:
1. Importing and applying schemas on the catalog.
2. Viewing the DDLs generated by combining schemas from shards.
The first operation is the default behavior and it requires a mandatory –schema parameter, which is list of schemas to import from shards. Note that all can be supplied to the -schema parameter to retrieve all non-Oracle schemas common to all shards and which do not exist on the catalog.This operation can be split into two steps using -retrieve_only and -apply options. The option -retrieve_only will retrieve schemas from the shards and generate the required DDL statements to be applied, but it does not execute these statements. To execute them at a later point, the -apply option is used. If, for some reason, a DDL execution fails, subsequent statements will not be executed as there could be dependencies on the failed DDL. When –apply is run again after fixing the issue, it will start from the first failed DDL statement and continue execution.
The second operation, -show is for examining DDL statements and their execution status.

Example

GDSCTL> sync schema -schema myschema
GDSCTL> sync schema -schema foo,bar
GDSCTL> sync schema -schema foo,"Bar"
GDSCTL> sync schema -schema all

validate backup

The validate backup command provides sharded database (SDB) backup validation.

Syntax

validate backup [-restorepoint restore_point_name] [-controlfile] [-header]
                          [-catpwd password] [-shard shard_list] [-async]

Options

Table C-121 GDSCTL validate backup Options

Option Description
-restorepoint restore_point_name

A restore point to verify the backups against.

-controlfile If specified, only backups usable to restore database control files to a specific restore point are validated.
-header If specified, it will only validate the backup file headers to determine whether the files on the media correspond to the metadata in the RMAN repository.
-catpwd password Password for user GSMCATUSER. Prompted if not specified. This password only needs to be specified once for this command in an entire GDSCTL session.
-shard shard_list shard_list specifies a comma separated list of shard identifiers. They can be shard space, shard group or shard names. The default is all shards.
-async When specified, all tasks to configure the backup for the shards will run in background. By default, the task will run in foreground. The task for the SDB catalog database will always run in foreground regardless of this flag setting.

Examples

The sharded database catalog (SC) database must be open, but the shard databases can be either mounted or open. If the backup validation is for database control files, the shards can be started nomount.The following example svalidates the backups of the control files from the SDB catalog database recoverable to restore point backup_before_db_maintenance.

GDSCTL> validate backup -shard catalog -controlfile -restorepoint BACKUP_BEFORE_DB_MAINTENANCE

validate catalog

Cross checks the Global Data Services catalog, global service manager run-time status, and pool databases, and reports inconsistencies and errors.

Syntax

validate [catalog] 
         [-gsm gsm_name]
         [ {-config | -database db_name} ] 
         [-catpwd cpwd]
         [-dbpwd dpwd]

Options

Table C-122 GDSCTL validate catalog Options

Option Description
-catpwd cpwd

Provides the GSMCATUSER password, otherwise it is read from the local wallet file by default.

-config

Indicates that the validation should be performed on the Global Data Services catalog configuration only.

-database db_name

Indicates the name of the database for which the cross-check validation should be performed.

-dbpwd dpwd

Provides the pool database password directly if there is only one database in the pool, or if multiple databases in the pool share the same password.

-gsm gsm_name

Specify the global service manager name. If the name is not specified, then GDSCTL uses the current global service manager name for the session (specified with the command set gsm).

Usage Notes

Because the execution of this command involves accessing all databases in a Global Data Services configuration, the GSMCATUSER password is required run it. The password is stored in the wallet of any global service manager that is part of the Global Data Services configuration. Therefore, if you run the command from the ORACLE_HOME of any of the global service managers, the password is automatically extracted from the wallet and does not have to be provided. Otherwise, you must provide the GSMCATUSER password using the -catpwd command option. Alternatively, if all databases in the Global Data Services configuration have the same GSMUSER password, you can specify the password instead of the GSMCATUSER password by using the -dbpwd option.

Example

Validate the catalog:

GDSCTL> validate

The output should be similar to the following:

Validation results:
VLD2: Region "regionora" does not have buddy region
VLD11: GDS pool "marketing" does not contain any databases
VLD12: GDS pool "marketing" does not contain any global services
VLD11: GDS pool "sales" does not contain any databases
VLD12: GDS pool "sales" does not contain any global services
VLD11: GDS pool "mkt" does not contain any databases
VLD12: GDS pool "mkt" does not contain any global services
