SUNW.oracle_server

, oracle_server

- resource type implementation for HA Oracle server

Description

The SUNW.oracle_server resource type represents the HA Oracle server in an Oracle Solaris Cluster configuration. The HA Oracle server resource is configured with an Oracle listener resource..

You must set the following properties for an Oracle server resource by using clresource(1CL).

Standard Properties

The standard resource property Failover is set for all failover resource types.

See r_properties(5) for a complete description of the following resource properties.

Failover_mode

Default: SOFT

Tunable: Any time

Retry_count

Minimum: -1

Maximum: 9999

Default: 2

Tunable: Any time

Retry_interval

Minimum: 0

Maximum: 2592000

Default: 1330

Tunable: Any time

Thorough_probe_interval

Minimum: 1

Maximum: 2592000

Default: 30

Tunable: Any time

Extension Properties

Alert_log_file

Type string. This property is set to the absolute path of the Oracle alert log file. The Oracle software logs alerts in this file. The Oracle server fault monitor scans the alert log file for new alerts at the following times:

  • When the server fault monitor is started

  • Each time that the server fault monitor queries the health of the server

If an action is defined for a logged alert that the server fault monitor detects, the server fault monitor performs the action in response to the alert.

You can modify this parameter any time.

When the Db_unique_name extension property is used, the Alert_log_file extension property is ignored and can be omitted from the HA-Oracle configuration.

Auto_end_bkp

Type Boolean. Default is FALSE. This property instructs the oracle_server START method to automatically recover the database during startup if the database had previously been interrupted during a hot backup.

If this property is set to TRUE, and the oracle_server START method detects the RDBMS error ORA-01113 file %s needs media recovery during startup, all files left in hot backup mode (as indicated by the sys.v$backup view). These files are automatically taken out of hot backup mode by using the command:

alter database datafile `filename` end backup;

The database is then opened for use.

If this property is set to FALSE, the oracle_server START method takes no recovery action following an ORA-01113 error, and the status of the resource is set to FAULTED. Manual intervention is required at this stage.

This property can be modified at any time.

Connect_cycle

Type integer. Default is 5. The Maximum value is 99999. The Oracle server fault monitor connects to the database periodically by using the user ID and password specified in Connect_string. The monitor disconnects after executing the number of probes specified in this property and then reconnects. You can modify this property at any time.

Connect_string

Type string. This property is set to the user ID and password of the database user in fault-monitor transactions. This property is specified as follows:

userid/password

As part of the HA Oracle setup, you must define the database user ID and password before enabling the server resource and its fault monitor. To use Solaris authentication, type a slash (/) instead of a user ID and password. This property must be set for standby databases as well. This property is used by the fault monitor after the physical standby database is transitioned to a primary database. You can modify this property at any time.

When the Db_unique_name extension property is used, the Connect_string extension property is ignored and can be omitted from the HA-Oracle configuration.

Custom_action_file

Type string. Default is NULL. This property specifies the absolute path of the file that defines the custom behavior of the Oracle Solaris Cluster HA for Oracle server fault monitor. The format of this file is defined in the custom_action_file(4) man page. You can modify this property at any time.

Dataguard_role

Type string. Default is NULL. This property specifies the role of the database. The permitted values for this property are as follows:

NONE

Specifies that no standby database instances are configured for the primary database instance.

PRIMARY

Specifies that the database is a primary database instance for which standby database instances are configured.

STANDBY

Specifies that the database role is standby. This value is used by Oracle Solaris Cluster HA for Oracle data service along with the Standby_mode property value to determine the role of the database.

IN_TRANSITION

Specifies that the database is undergoing a role reversal process. This value must be set, when a role reversal process is to be applied to the database. The Dataguard_role and Standby_mode properties must be set after the role reversal process is complete to reflect the correct role of the database.

You can modify this property at any time.

Db_unique_name

Type string. This property is required when a single-instance HA for Oracle data service is deployed using Oracle 11g release 2 Grid Infrastructure for Clusters. The db_unique_name extension property specifies the unique name of the single-instance database that is being deployed.

When the db_unique_name extension property is used, the following extension properties are ignored and can be omitted from the HA-Oracle configuration:

  • Alert_log_file

  • Connect_string

You can modify this property at any time.

Debug_level

Type integer. Default is 1. Maximum value is 100. This property indicates the level to which debug messages from the fault monitor of the Oracle server component are logged. When the debug level is increased, more debug messages are written to the log files. These messages are logged to the file /var/opt/SUNWscor/oracle_server/message_log.rs, where rs is the name of the resource that represents the Oracle server component. You can modify this property at any time.

Oracle_Home

Type string. This property is set to the Oracle parent directory that contains the binaries, logs, and parameter files. You can modify this property only when the resource is disabled.

Oracle_Sid

Type string. This property is set to the name of the Oracle database instance (also called the Oracle system identifier). You can modify this property only when the resource is disabled.

Parameter_file

Type string. This property is set to the Oracle parameter file, which starts the database. If this property is not set, it defaults to $ORACLE_HOME/dbs/init$ORACLE_SID.ora. If the default value is not found, Oracle Solaris Cluster HA for Oracle checks for $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora. You can modify this property at any time.

Probe_timeout

Type integer. Default is 300 seconds. Maximum value is 99999. This property is the timeout value (in seconds) that is used by the fault monitor to probe an Oracle server instance. You can modify this property at any time.

Restart_type

Type enumeration. Default is RESOURCE_RESTART. This property specifies the entity that the server fault monitor restarts when the response to a fault is restart. The permitted values for this property are as follows:

RESOURCE_RESTART

Specifies that only this resource is restarted.

RESOURCE_GROUP_RESTART

Specifies that all resources in the resource group that contains this resource are restarted.

You can modify this property at any time.

Standby_mode

Type string. Default is LOGICAL. This property specifies the mode of the standby database. This property is used by Oracle Solaris Cluster HA for Oracle data service only when the Dataguard_role property is set to STANDBY to determine the type of standby database. The permitted values for this property are as follows:

LOGICAL

Specifies a logical standby database.

PHYSICAL

Specifies a physical standby database.

You can modify this property at any time.

User_env

Type string. Default is NULL. This property is set to the name of the file that contains the environment variables to be set before database startup or shutdown. You can modify this property at any time.

Wait_for_online

Type Boolean. Default is TRUE. This property specifies whether the oracle_server START method waits for the database to be online before exiting. If this property is set to FALSE, oracle_server START executes the commands to start the database but does not wait for it to come online before exiting. You can modify this property at any time.

Examples

Example 1 Creating a Failover oracle_server Resource

For this example to work, the data service must first be installed.

The following example creates a failover oracle_server resource named ora_server in an existing resource group named oracle-rg. oracle-rg is assumed to contain a LogicalHostname resource, which identifies the logical hostname associated with the resource group, and an oracle_listener resource, which identifies the Oracle listener associated with the resource group.

example# clresourcetype register SUNW.oracle_server 
example# clresource create –g oracle-rg \ 
–t SUNW.oracle_server -p CONNECT_STRING=scott/tiger \ 
–p ORACLE_SID=oraSID –p ORACLE_HOME=/oracle \ 
–p ALERT_LOG_FILE=/oracle/admin/oraSID/bdump/alert_oraSID.log ora_server 

In this example, the Oracle server resource created is named ora_server, which has its ORACLE_HOME under /oracle. The SID of the is ora_server is oraSID. Its fault monitor uses the user ID scott and the password tiger to connect to the database. The alert log file scanned by the fault monitor for any errors that have occurred is at /oracle/admin/oraSID/bdump/alert_oraSID.log.
