Syntax


DBMS_REPCAT.ADD_GROUPED_COLUMN ( 
   sname                 IN   VARCHAR2,
   oname                 IN   VARCHAR2,
   column_group          IN   VARCHAR2,
   list_of_column_names  IN   VARCHAR2 | DBMS_REPCAT.VARCHAR2s);

Parameters

Table 18-2 ADD_GROUPED_COLUMN Procedure Parameters

Parameter Description
sname

Schema in which the replicated table is located.

oname

Name of the replicated table with which the column group is associated. The table can be the storage table of a nested table.

column_group

Name of the column group to which you are adding members.

list_of_column_names

Names of the columns that you are adding to the designated column group. This can either be a comma-delimited list or a PL/SQL index-by table of column names. The PL/SQL index-by table must be of type DBMS_REPCAT.VARCHAR2. Use the single value '*' to create a column group that contains all of the columns in your table.

You can specify column objects, but you cannot specify attributes of column objects.

If the table is an object, then you can specify SYS_NC_OID$ to add the object identifier column to the column group. This column tracks the object identifier of each row object.

Parameters

Table 18-4 ADD_MASTER_DATABASE Procedure Parameters

Parameter Description
gname

Name of the replication group being replicated. This replication group must already exist at the master definition site.

master

Fully qualified database name of the new master database.

use_existing_objects

Indicate TRUE if you want to reuse any objects of the same type and shape that already exist in the schema at the new master site.

ADD_NEW_MASTERS Procedure

This procedure adds the master sites in the DBA_REPSITES_NEW data dictionary view to the master groups specified when the SPECIFY_NEW_MASTERS procedure was run. Information about these new master sites are added to the replication catalog at all available master sites.

All master sites instantiated with object-level export/import must be accessible at this time. Their new replication groups are added in the quiesced state. Master sites instantiated through full database export/import or through changed-based recovery do not need to be accessible.

Run this procedure after you run the SPECIFY_NEW_MASTERS procedure.

Caution:

After running this procedure, do not disable or enable propagation of the deferred transactions queue until after the new master sites are added. The DBA_REPEXTENSIONS data dictionary view must be clear before you disable or enable propagation. You can use the Advanced Replication interface in Oracle Enterprise Manager or the SET_DISABLED procedure in the DBMS_DEFER_SYS package to disable or enable propagation.

Syntax


DBMS_REPCAT.ADD_NEW_MASTERS (
   export_required                IN    BOOLEAN,
   { available_master_list        IN    VARCHAR2, 
   | available_master_table       IN    DBMS_UTILITY.DBLINK_ARRAY,}

   cycle_seconds_new              IN    BINARY_INTEGER  := 60);

Note:

This procedure is overloaded. The available_master_list and available_master_table parameters are mutually exclusive.

Parameters

Table 18-6 ADD_NEW_MASTERS Procedure Parameters

Parameter Description
export_required

Set to TRUE if either object-level or full database export is required for at least one of the new master sites. Set to FALSE if you are using change-based recovery for all of the new master sites.

available_master_list

A comma-delimited list of the new master sites to be instantiated using object-level export/import. The sites listed must match the sites specified in the SPECIFY_NEW_MASTERS procedure. List only the new master sites, not the existing master sites. Do not put any spaces between site names.

Specify NULL if all masters will be instantiated using full database export/import or change-based recovery.

available_master_table

A table that lists the new master sites to be instantiated using object-level export/import. The sites in the table must match the sites specified in the SPECIFY_NEW_MASTERS procedure. Do not specify masters that will be instantiated using full database export/import or change-based recovery.

In the table that lists the master sites to be instantiated using object-level export/import, list only the new master sites for the master groups being extended. Do not list the existing master sites in the master groups being extended. The first master site should be at position 1, the second at position 2, and so on.

masterdef_flashback_scn

This OUT parameter returns a system change number (SCN) that must be used during export or change-based recovery. Use the value returned by this parameter for the FLASHBACK_SCN export parameter when you perform the export. You can find the flashback_scn value by querying the DBA_REPEXTENSIONS data dictionary view.

extension_id

This OUT parameter returns an identifier for the current pending request to add master databases without quiesce. You can find the extension_id by querying the DBA_REPSITES_NEW and DBA_REPEXTENSIONS data dictionary views.

break_trans_to_masterdef

This parameter is meaningful only if export_required is set to TRUE.

If break_trans_to_masterdef is set to TRUE, then existing masters can continue to propagate their deferred transactions to the master definition site for replication groups that are not adding master sites. Deferred transactions for replication groups that are adding master sites cannot be propagated until the export completes.

Each deferred transaction is composed of one or more remote procedure calls (RPCs). If set to FALSE and a transaction occurs that references objects in both unaffected master groups and master groups that are being extended, then the transaction might be split into two parts and sent to a destination in two separate transactions at different times. Such transactions are called split-transactions. If split-transactions are possible, then you must disable integrity constraints that might be violated by this behavior until the new master sites are added.

If break_trans_to_masterdef is set to FALSE, then existing masters cannot propagate their deferred transactions to the master definition site.

break_trans_to_new_masters

If break_trans_to_new_masters is set to TRUE, then existing master sites can continue to propagate deferred transactions to the new master sites for replication groups that are not adding master sites.

Each deferred transaction is composed of one or more remote procedure calls (RPCs). If set to TRUE and a transaction occurs that references objects in both unaffected master groups and master groups that are being extended, then the transaction might be split into two parts and sent to a destination in two separate transactions at different times. Such transactions are called split-transactions. If split-transactions are possible, then you must disable integrity constraints that might be violated by this behavior until the new master sites are added.

If break_trans_to_new_masters is set to FALSE, then propagation of deferred transaction queues to the new masters is disabled.

percentage_for_catchup_mdef

This parameter is meaningful only if export_required and break_trans_to_masterdef are both set to TRUE.

The percentage of propagation resources that should be used for catching up propagation to the master definition site. Must be a multiple of 10 and must be between 0 and 100.

cycle_seconds_mdef

This parameter is meaningful when percentage_for_catchup_mdef is both meaningful and set to a value between 10 and 90, inclusive. In this case, propagation to the master definition site alternates between replication groups that are not being extended and replication groups that are being extended, with one push to each during each cycle. This parameter indicates the length of the cycle in seconds.

percentage_for_catchup_new

This parameter is meaningful only if break_trans_to_new_masters is set to TRUE.

The percentage of propagation resources that should be used for catching up propagation to new master sites. Must be a multiple of 10 and must be between 0 and 100.

cycle_seconds_new

This parameter is meaningful when percentage_for_catchup_new is both meaningful and set to a value between 10 and 90, inclusive. In this case, propagation to a new master alternates between replication groups that are not being extended and replication groups that are being extended, with one push to each during each cycle. This parameter indicates the length of the cycle in seconds.


Exceptions

Table 18-7 ADD_NEW_MASTERS Procedure Exceptions

Exception Description
nonmasterdef

Invocation site is not the master definition site.

typefailure

The parameter value specified for one of the parameters is not appropriate.

novalidextreq

No valid extension request. The extension_id is not valid.

nonewsites

No new master sites to be added for the specified extension request.

notanewsite

Not a new site for extension request. A site was specified that was not specified when you ran the SPECIFY_NEW_MASTERS procedure.

dbnotcompatible

Feature is incompatible with database version. All databases must be at 9.2.0 or higher compatibility level.


Usage Notes

For a new master site to be instantiated using change-based recovery or full database export/import, the following conditions apply:

For object-level export/import, before importing ensure that all the requests in the DBA_REPCATLOG data dictionary view for the extended groups have been processed without any error.

Note:

To use change-based recovery, the existing master site and the new master site must be running under the same operating system, although the release of the operating system can differ.

ADD_PRIORITY_datatype Procedure

This procedure adds a member to a priority group. You must call this procedure from the master definition site. The procedure that you must call is determined by the data type of your priority column. You must call this procedure once for each of the possible values of the priority column.

Parameters

Table 18-13 ADD_conflicttype_RESOLUTION Procedure Parameters

Parameter Description
sname

Name of the schema containing the table to be replicated.

oname

Name of the table to which you are adding a conflict resolution routine. The table can be the storage table of a nested table.

column_group

Name of the column group to which you are adding a conflict resolution routine. Column groups are required for update conflict resolution routines only.

constraint_name

Name of the unique constraint or unique index for which you are adding a conflict resolution routine. Use the name of the unique index if it differs from the name of the associated unique constraint. Constraint names are required for uniqueness conflict resolution routines only.

sequence_no

Order in which the designated conflict resolution methods should be applied.

method

Type of conflict resolution routine that you want to create. This can be the name of one of the standard routines provided with advanced replication, or, if you have written your own routine, you should choose user function, and provide the name of your method as the function_name parameter.

The standard methods supported in this release for update conflicts are:

  • minimum

  • maximum

  • latest timestamp

  • earliest timestamp

  • additive, average

  • priority group

  • site priority

  • overwrite

  • discard

The standard methods supported in this release for uniqueness conflicts are: append site name, append sequence, and discard. There are no built-in (Oracle supplied) methods for delete conflicts.

parameter_column_name

Name of the columns used to resolve the conflict. The standard methods operate on a single column. For example, if you are using the latest timestamp method for a column group, then you should pass the name of the column containing the time stamp value as this parameter. If your are using a user function, then you can resolve the conflict using any number of columns.

For update or unique conflicts, this parameter accepts either a comma-delimited list of column names, or a PL/SQL index-by table of type DBMS_REPCAT.VARCHAR2 or DBMS_UTILITY.LNAME_ARRAY. Use DBMS_UTILITY.LNAME_ARRAY if any column name is greater than or equal to 30 bytes, which might occur when you specify the attributes of column objects.

For delete conflicts, this parameter accepts either a comma-delimited list of column names or a PL/SQL index-by table of type DBMS_REPCAT.VARCHAR2.

The single value '*' indicates that you want to use all of the columns in the table (or column group, for update conflicts) to resolve the conflict. If you specify '*', then the columns are passed to your function in alphabetical order.

LOB columns cannot be specified for this parameter.

See Also: "Usage Notes" if you are using column objects

priority_group

If you are using the priority group or site priority update conflict resolution method, then you must supply the name of the priority group that you have created.

See Chapter 6, "Configuring Conflict Resolution" and Oracle Database Advanced Replication for more information. If you are using a different method, you can use the default value for this parameter, NULL. This parameter is applicable to update conflicts only.

function_name

If you selected the user function method, or if you are adding a delete conflict resolution routine, then you must supply the name of the conflict resolution routine that you have written. If you are using one of the standard methods, then you can use the default value for this parameter, NULL.

ALTER_CATCHUP_PARAMETERS Procedure

This procedure alters the values for the following parameters stored in the DBA_REPEXTENSIONS data dictionary view:

These parameters were originally set by the ADD_NEW_MASTERS procedure. The new values you specify for these parameters are used during the remaining steps in the process of adding new master sites to a master group. These changes are only to the site at which it is executed. Therefore, it must be executed at each master site, including the master definition site, if you want to alter parameters at all sites.

Syntax

DBMS_REPCAT.ALTER_CATCHUP_PARAMETERS (
   extension_id                  IN    RAW,   
   percentage_for_catchup_mdef   IN    BINARY_INTEGER  := NULL,
   cycle_seconds_mdef            IN    BINARY_INTEGER  := NULL,    
   percentage_for_catchup_new    IN    BINARY_INTEGER  := NULL,    
   cycle_seconds_new             IN    BINARY_INTEGER  := NULL);

Parameters

Table 18-15 ALTER_CATCHUP_PARAMETERS Procedure Parameters

Parameter Description
extension_id

The identifier for the current pending request to add master database without quiesce. You can find the extension_id by querying the DBA_REPSITES_NEW and DBA_REPEXTENSIONS data dictionary views.

percentage_for_catchup_mdef

The percentage of propagation resources that should be used for catching up propagation to the master definition site. Must be a multiple of 10 and must be between 0 and 100.

cycle_seconds_mdef

This parameter is meaningful when percentage_for_catchup_mdef is both meaningful and set to a value between 10 and 90, inclusive. In this case, propagation to the master definition site alternates between replication groups that are not being extended and replication groups that are being extended, with one push to each during each cycle. This parameter indicates the length of the cycle in seconds.

percentage_for_catchup_new

The percentage of propagation resources that should be used for catching up propagation to new master sites. Must be a multiple of 10 and must be between 0 and 100.

cycle_seconds_new

This parameter is meaningful when percentage_for_catchup_new is both meaningful and set to a value between 10 and 90, inclusive. In this case, propagation to a new master alternates between replication groups that are not being extended and replication groups that are being extended, with one push to each during each cycle. This parameter indicates the length of the cycle in seconds.


Exceptions

dbnotcompatible

Feature is incompatible with database version. All databases must be at 9.2.0 or higher compatibility level.



ALTER_MASTER_PROPAGATION Procedure

This procedure alters the propagation method for a specified replication group at a specified master site. This replication group must be quiesced. You must call this procedure from the master definition site. If the master appears in the dblink_list or dblink_table, then ALTER_MASTER_PROPAGATION ignores that database link. You cannot change the propagation mode from a master to itself.

Syntax

DBMS_REPCAT.ALTER_MASTER_PROPAGATION (
   gname               IN   VARCHAR2, 
   master              IN   VARCHAR2,
   { dblink_list       IN   VARCHAR2, 
   | dblink_table      IN   DBMS_UTILITY.DBLINK_ARRAY,}
   propagation_mode    IN   VARCHAR2 : ='ASYNCHRONOUS',
   comment             IN   VARCHAR2 := '');

Note:

This procedure is overloaded. The dblink_list and dblink_table parameters are mutually exclusive.

Parameters

Table 18-17 ALTER_MASTER_PROPAGATION Procedure Parameters

Parameter Description
gname

Name of the replication group to which to alter the propagation mode.

master

Name of the master site at which to alter the propagation mode.

dblink_list

A comma-delimited list of database links for which to alter the propagation method. If NULL, then all masters except the master site being altered are used by default.

dblink_table

A PL/SQL index-by table, indexed from position 1, of database links for which to alter propagation.

propagation_mode

Determines the manner in which changes from the specified master site are propagated to the sites identified by the list of database links. Appropriate values are synchronous and asynchronous.

comment

This comment is added to the DBA_REPPROP view.


Exceptions

Table 18-18 ALTER_MASTER_PROPAGATION Procedure Exceptions

Exception Description
nonmasterdef

Invocation site is not the master definition site.

notquiesced

Invocation site is not quiesced.

typefailure

Propagation mode specified was not recognized.

nonmaster

List of database links includes a site that is not a master site.



ALTER_MASTER_REPOBJECT Procedure

This procedure alters an object in your replication environment. You must call this procedure from the master definition site.

This procedure requires that you quiesce the master group of the object if either of the following conditions is true:

You can use this procedure to alter non table objects without quiescing the master group.

Syntax


DBMS_REPCAT.ALTER_MASTER_REPOBJECT (
   sname               IN   VARCHAR2, 
   oname               IN   VARCHAR2, 
   type                IN   VARCHAR2, 
   ddl_text            IN   VARCHAR2, 
   comment             IN   VARCHAR2     := '', 
   retry               IN   BOOLEAN      := FALSE
   safe_table_change   IN   BOOLEAN      := FALSE);

Parameters

Table 18-19 ALTER_MASTER_REPOBJECT Procedure Parameters

Parameter Description
sname

Schema containing the object that you want to alter.

oname

Name of the object that you want to alter. The object cannot be a storage table for a nested table.

type

Type of the object that you are altering. The following types are supported:

FUNCTION               SYNONYM
INDEX                  TABLE
INDEXTYPE              TRIGGER
OPERATOR               TYPE
PACKAGE                TYPE BODY
PACKAGE BODY           VIEW
PROCEDURE
ddl_text

The DDL text that you want used to alter the object. Oracle does not parse this DDL before applying it. Therefore, you must ensure that your DDL text provides the appropriate schema and object name for the object being altered.

If the DDL is supplied without specifying a schema, then the default schema is the replication administrator's schema. Be sure to specify the schema if it is other than the replication administrator's schema.

comment

If not NULL, then this comment is added to the COMMENT field of the DBA_REPOBJECT view.

retry

If retry is TRUE, then ALTER_MASTER_REPOBJECT alters the object only at masters whose object status is not VALID.

safe_table_change

Specify TRUE if the change to a table is safe. Specify FALSE if the change to a table is unsafe.

You can make safe changes to a master table in a single master replication environment without quiescing the master group that contains the table. To make unsafe changes, you must quiesce the master group.

Only specify this parameter for tables in single master replication environments. This parameter is ignored in multimaster replication environments and when the object specified is not a table. In multimaster replication environments, you must quiesce the master group to run the ALTER_MASTER_REPOBJECT procedure on a table.

The following are safe changes:

  • Changing storage and extent information

  • Making existing columns larger. For example, changing a VARCHAR2(20) column to a VARCHAR2(50) column.

  • Adding non primary key constraints

  • Altering non primary key constraints

  • Enabling and disabling non primary key constraints

The following are unsafe changes:

  • Changing the primary key by adding or deleting columns in the key

  • Adding or deleting columns

  • Making existing columns smaller. For example, changing a VARCHAR2(50) column to a VARCHAR2(20) column.

  • Disabling a primary key constraint

  • Changing the data type of an existing column

  • Dropping an existing column

If you are unsure whether a change is safe or unsafe, then quiesce the master group before you run the ALTER_MASTER_REPOBJECT procedure.

COMPARE_OLD_VALUES Procedure

This procedure specifies whether to compare old column values during propagation of deferred transactions at each master site for each nonkey column of a replicated table for updates and deletes. The default is to compare old values for all columns. You can change this behavior at all master sites and materialized view sites by invoking DBMS_REPCAT.COMPARE_OLD_VALUES at the master definition site.

When you use user-defined types, you can specify leaf attributes of a column object, or you can specify an entire column object. For example, if a column object named cust_address has street_address as an attribute, then you can specify cust_address.street_address for the column_list parameter or as part of the column_table parameter, or you can specify only cust_address.

When performing equality comparisons for conflict detection, Oracle treats objects as equal only if one of the following conditions is true:

Given these conditions, if one object is atomically NULL while the other is not, then Oracle does not consider the objects to be equal. Oracle does not consider MAP and ORDER methods when performing equality comparisons.

Syntax

DBMS_REPCAT.COMPARE_OLD_VALUES(
   sname           IN  VARCHAR2,
   oname           IN  VARCHAR2,
   { column_list   IN  VARCHAR2,
   | column_table  IN  DBMS_UTILITY.VARCHAR2s | DBMS_UTILITY.LNAME_ARRAY,}
   operation       IN  VARCHAR2 := 'UPDATE',
   compare         IN  BOOLEAN  := TRUE );

Note:

This procedure is overloaded. The column_list and column_table parameters are mutually exclusive.

Parameters

Table 18-50 COMPARE_OLD_VALUES Procedure Parameters

Parameter Description
sname

Schema in which the table is located.

oname

Name of the replicated table. The table can be the storage table of a nested table.

column_list

A comma-delimited list of the columns in the table. There must be no spaces between entries.

column_table

Instead of a list, you can use a PL/SQL index-by table of type DBMS_REPCAT.VARCHAR2 or DBMS_UTILITY.LNAME_ARRAY to contain the column names. The first column name should be at position 1, the second at position 2, and so on.

Use DBMS_UTILITY.LNAME_ARRAY if any column name is greater than or equal to 30 bytes, which might occur when you specify the attributes of column objects.

operation

Possible values are: update, delete, or the asterisk wildcard '*', which means update and delete.

compare

If compare is TRUE, the old values of the specified columns are compared when sent. If compare is FALSE, the old values of the specified columns are not compared when sent. Unspecified columns and unspecified operations are not affected. The specified change takes effect at the master definition site as soon as min_communication is TRUE for the table. The change takes effect at a master site or at a materialized view site the next time replication support is generated at that site with min_communication TRUE.


Note:

The operation parameter enables you to decide whether or not to compare old values for nonkey columns when rows are deleted or updated. If you do not compare the old value, then Oracle assumes the old value is equal to the current value of the column at the target side when the update or delete is applied.

See Oracle Database Advanced Replication for more information about reduced data propagation using the COMPARE_OLD_VALUES procedure before changing the default behavior of Oracle.

Exceptions

Table 18-51 COMPARE_OLD_VALUES Procedure Exceptions

Exception Description
nonmasterdef

Invocation site is not the master definition site.

missingobject

Specified object does not exist as a table in the specified schema waiting for row-level replication information.

missingcolumn

At least one column is not in the table.

notquiesced

Master group has not been quiesced.

typefailure

An illegal operation is specified.

keysendcomp

A specified column is a key column in a table.

dbnotcompatible

Feature is incompatible with database version. Typically, this exception arises when you are trying to compare the attributes of column objects. In this case, all databases must be at 9.2.0 or higher compatibility level.



CREATE_MASTER_REPGROUP Procedure

CREATE_MASTER_REPOBJECT Procedure

This procedure makes an object a replicated object by adding the object to a master group. This procedure preserves the object identifier for user-defined types and object tables at all replication sites.

Replication of clustered tables is supported, but the use_existing_object parameter cannot be set to FALSE for clustered tables. In other words, you must create the clustered table at all master sites participating in the master group before you execute the CREATE_MASTER_REPOBJECT procedure. However, these tables do not need to contain the table data. So, the copy_rows parameter can be set to TRUE for clustered tables.

Syntax


DBMS_REPCAT.CREATE_MASTER_REPOBJECT (
   sname                IN   VARCHAR2,
   oname                IN   VARCHAR2, 
   type                 IN   VARCHAR2,
   use_existing_object  IN   BOOLEAN     := TRUE, 
   ddl_text             IN   VARCHAR2    := NULL, 
   comment              IN   VARCHAR2    := '', 
   retry                IN   BOOLEAN     := FALSE,
   copy_rows            IN   BOOLEAN     := TRUE,
   gname                IN   VARCHAR2    := '');

Parameters

Table 18-54 CREATE_MASTER_REPOBJECT Procedure Parameters

Parameters Description
sname

Name of the schema in which the object that you want to replicate is located.

oname

Name of the object you are replicating. If ddl_text is NULL, then this object must already exist in the specified schema. To ensure uniqueness, table names should be a maximum of 27 bytes long, and package names should be no more than 24 bytes. The object cannot be a storage table for a nested table.

type

Type of the object that you are replicating. The following types are supported:

FUNCTION                SYNONYM
INDEX                   TABLE
INDEXTYPE               TRIGGER
OPERATOR                TYPE
PACKAGE                 TYPE BODY
PACKAGE BODY            VIEW
PROCEDURE
use_existing_object

Indicate TRUE if you want to reuse any objects of the same type and shape at the current master sites. See Table 18-56 for more information.

Note: This parameter must be set to TRUE for clustered tables.

ddl_text

If the object does not already exist at the master definition site, then you must supply the DDL text necessary to create this object. PL/SQL packages, package bodies, procedures, and functions must have a trailing semicolon. SQL statements do not end with trailing semicolon. Oracle does not parse this DDL before applying it; therefore, you must ensure that your DDL text provides the appropriate schema and object name for the object being created.

If the DDL is supplied without specifying a schema (sname parameter), then the default schema is the replication administrator's schema. Be sure to specify the schema if it is other than the replication administrator's schema.

Note: Do not use the ddl_text parameter to add user-defined types or object tables. Instead, create the object first and then add the object.

comment

This comment is added to the OBJECT_COMMENT field of the DBA_REPOBJECT view.

retry

Indicate TRUE if you want Oracle to reattempt to create an object that it was previously unable to create. Use this if the error was transient or has since been rectified, or if you previously had insufficient resources. If this is TRUE, then Oracle creates the object only at master sites whose object status is not VALID.

copy_rows

Indicate TRUE if you want the initial contents of a newly replicated object to match the contents of the object at the master definition site. See Table 18-56 for more information.

gname

Name of the replication group in which you want to create the replicated object. The schema name is used as the default replication group name if none is specified, and a replication group with the same name as the schema must exist for the procedure to complete successfully in that case.


Exceptions

Exceptions Description
nonmasterdef

Invocation site is not the master definition site.

notquiesced

CREATE_MVIEW_REPOBJECT Procedure

This procedure adds a replicated object to a materialized view group.

Syntax


DBMS_REPCAT.CREATE_MVIEW_REPOBJECT (
   sname                   IN   VARCHAR2,
   oname                   IN   VARCHAR2, 
   type                    IN   VARCHAR2,

   generate_80_compatible  IN   BOOLEAN   := TRUE,
   gowner                  IN   VARCHAR2  := 'PUBLIC');

Parameters

Table 18-59 CREATE_MVIEW_REPOBJECT Procedure Parameters

Parameter Description
sname

Name of the schema in which the object is located. The schema must be same as the schema that owns the master table or master materialized view on which this materialized view is based.

oname

Name of the object that you want to add to the replicated materialized view group.

type

Type of the object that you are replicating. The following types are supported:

FUNCTION               SNAPSHOT
INDEX                  SYNONYM
INDEXTYPE              TRIGGER
OPERATOR               TYPE
PACKAGE                TYPE BODY
PACKAGE BODY           VIEW
PROCEDURE

Use SNAPSHOT type of the object is a materialized view.

ddl_text

For objects of type MATERIALIZED VIEW, the DDL needed to create the object. For other types, use the default:

'' (an empty string)

If a materialized view with the same name already exists, then Oracle ignores the DDL and registers the existing materialized view as a replicated object. If the master table or master materialized view for a materialized view does not exist in the replication group of the master designated for this schema, then Oracle raises a missingobject error.

If the DDL is supplied without specifying a schema, then the default schema is the replication administrator's schema. Be sure to specify the schema if it is other than the replication administrator's schema.

If the object is not of type MATERIALIZED VIEW, then the materialized view site connects to the master site or master materialized view site and pulls down the DDL text to create the object. If the object type is TYPE or TYPE BODY, then the object identifier (OID) for the object at the materialized view site is the same as the OID at the master site or master materialized view site.

comment

This comment is added to the OBJECT_COMMENT field of the DBA_REPOBJECT view.

gname

Name of the replicated materialized view group to which you are adding an object. The schema name is used as the default group name if none is specified, and a materialized view group with the same name as the schema must exist for the procedure to complete successfully.

gen_objs_owner

Name of the user you want to assign as owner of the transaction.

min_communication

This parameter is obsolete. Use the default value (TRUE).

generate_80_compatible

Set to FALSE because interoperability is not supported between Oracle8i databases and Oracle 11g or later databases.

gowner

Owner of the materialized view group.

Parameters

Table 18-73 DROP_MASTER_REPGROUP Procedure Parameters

Parameter Description
gname

Name of the master group that you want to drop from the current master site.

drop_contents

By default, when you drop the replication group at a master site, all of the objects remain in the database. They simply are no longer replicated. That is, the replicated objects in the replication group no longer send changes to, or receive changes from, other master sites. If you set this to TRUE, then any replicated objects in the master group are dropped from their associated schemas.

all_sites

If this is TRUE and if the invocation site is the master definition site, then the procedure synchronously multicasts the request to all masters. In this case, execution is immediate at the master definition site and might be deferred at all other master sites.

PREPARE_INSTANTIATED_MASTER Procedure

This procedure enables the propagation of deferred transactions from other prepared new master sites and existing master sites to the invocation master site. This procedure also enables the propagation of deferred transactions from the invocation master site to the other prepared new master sites and existing master sites.

If you performed a full database export/import or a change-based recovery, then the new master site includes all of the deferred transactions that were in the deferred transactions queue at the master definition site. Because these deferred transactions should not exist at the new master site, this procedure deletes all transactions in the deferred transactions queue and error queue if full database export/import or change-based recovery was used.

For object-level export/import, ensure that all the requests in the DBA_REPCATLOG data dictionary view for the extended groups have been processed without error before running this procedure.

Caution:

  • Do not invoke this procedure until instantiation (export/import or change-based recovery) for the new master site is complete.

  • Do not allow any data manipulation language (DML) statements directly on the objects in the extended master group in the new master site until execution of this procedure returns successfully. These DML statements might not be replicated.

  • Do not use the DBMS_DEFER package to create deferred transactions until execution of this procedure returns successfully. These deferred transactions might not be replicated.

Note:

To use change-based recovery, the existing master site and the new master site must be running under the same operating system, although the release of the operating system can differ.

Syntax


DBMS_REPCAT.PREPARE_INSTANTIATED_MASTER (
   extension_id             IN       RAW);

RESUME_PROPAGATION_TO_MDEF Procedure

During the process of adding new master sites to a master group without quiesce, this procedure indicates that export is effectively finished and propagation to the master definition site for both extended and unaffected replication groups existing at master sites can be enabled. Run this procedure after the export required to add new master sites to a master group is complete.

See Also:

"Adding New Master Sites" for more information about adding master sites to a master group

Syntax


DBMS_REPCAT.RESUME_PROPAGATION_TO_MDEF (
   extension_id    IN    RAW);

Parameters

Table 18-124 RESUME_PROPAGATION_TO_MDEF Procedure Parameters

Parameter Description
extension_id

The identifier for the current pending request to add master databases to a master group without quiesce. You can find the extension_id by querying the DBA_REPSITES_NEW and DBA_REPEXTENSIONS data dictionary views.


Exceptions

Table 18-125 RESUME_PROPAGATION_TO_MDEF Procedure Exceptions

Exception Description
nonmasterdef

Invocation site is not the master definition site.

extstinapp

Extension status is inappropriate. The extension status should be EXPORTING when you run this procedure. To check the extension status, query the DBA_REPEXTENSIONS data dictionary view.

dbnotcompatible

Feature is incompatible with database version. All databases must be at 9.2.0 or higher compatibility level.



SEND_OLD_VALUES Procedure

You have the option of sending old column values during propagation of deferred transactions for each nonkey column of a replicated table when rows are updated or deleted in the table. When min_communication is set to TRUE, the default is the following:

You can change this behavior at all master sites and materialized view sites by invoking DBMS_REPCAT.SEND_OLD_VALUES at the master definition site. Then, generate replication support at all master sites and at each materialized view site.

When you use user-defined types, you can specify the leaf attributes of a column object, or an entire column object. For example, if a column object named cust_address has street_address as an attribute, then you can specify cust_address.street_address for the column_list parameter or as part of the column_table parameter, or you can specify only cust_address.

Syntax

DBMS_REPCAT.SEND_OLD_VALUES(
   sname           IN  VARCHAR2,
   oname           IN  VARCHAR2,
   { column_list   IN  VARCHAR2,
   | column_table  IN  DBMS_UTILITY.VARCHAR2s | DBMS_UTILITY.LNAME_ARRAY,}
   operation       IN  VARCHAR2 := 'UPDATE',
   send            IN  BOOLEAN  := TRUE );

Note:

This procedure is overloaded. The column_list and column_table parameters are mutually exclusive.

Parameters

Table 18-126 SEND_OLD_VALUES Procedure Parameters

Parameter Description
sname

Schema in which the table is located.

oname

Name of the replicated table. The table can be the storage table of a nested table.

column_list

A comma-delimited list of the columns in the table. There must be no spaces between entries.

column_table

Instead of a list, you can use a PL/SQL index-by table of type DBMS_REPCAT.VARCHAR2 or DBMS_UTILITY.LNAME_ARRAY to contain the column names. The first column name should be at position 1, the second at position 2, and so on.

Use DBMS_UTILITY.LNAME_ARRAY if any column name is greater than or equal to 30 bytes, which might occur when you specify the attributes of column objects.

operation

Possible values are: update, delete, or the asterisk wildcard '*', which means update and delete.

send

If TRUE, then the old values of the specified columns are sent. If FALSE, then the old values of the specified columns are not sent. Unspecified columns and unspecified operations are not affected.

The specified change takes effect at the master definition site as soon as min_communication is TRUE for the table. The change takes effect at a master site or at a materialized view site the next time replication support is generated at that site with min_communication TRUE.


Note:

The operation parameter enables you to specify whether or not to transmit old values for nonkey columns when rows are deleted or updated. If you do not send the old value, then Oracle sends a NULL in place of the old value and assumes the old value is equal to the current value of the column at the target side when the update or delete is applied.

See Oracle Database Advanced Replication for information about reduced data propagation using the SEND_OLD_VALUES procedure before changing the default behavior of Oracle.

Exceptions

Table 18-127 SEND_OLD_VALUES Procedure Exceptions

Exception Description
nonmasterdef

Invocation site is not the master definition site.

missingobject

Specified object does not exist as a table in the specified schema waiting for row-level replication information.

missingcolumn

At least one column is not in the table.

notquiesced

Master group has not been quiesced.

typefailure

An illegal operation is specified.

keysendcomp

A specified column is a key column in a table.

dbnotcompatible

Feature is incompatible with database version. Typically, this exception arises when you are trying to send the attributes of column objects. In this case, all databases must be at 9.2.0 or higher compatibility level.



SET_COLUMNS Procedure

This procedure enables you to use an alternate column or group of columns, instead of the primary key, to determine which columns of a table to compare when using row-level replication. You must call this procedure from the master definition site.

When you use column objects, if an attribute of a column object can be used as a primary key or part of a primary key, then the attribute can be part of an alternate key column. For example, if a column object named cust_address has street_address as a VARCHAR2 attribute, then you can specify cust_address.street_address for the column_list parameter or as part of the column_table parameter. However, the entire column object, cust_address, cannot be specified.

For the storage table of a nested table column, this procedure accepts the NESTED_TABLE_ID as an alternate key column.

When you use object tables, you cannot specify alternate key columns. If the object identifier (OID) is system-generated for an object table, then Oracle uses the OID column in the object table as the key for the object table. If the OID is user-defined for an object table, then Oracle uses the primary key in the object table as the key.

The following types of columns cannot be alternate key columns:

See Also:

The constraint_clause in Oracle Database SQL Language Reference for more information about restrictions on primary key columns

Syntax

DBMS_REPCAT.SET_COLUMNS (
   sname           IN    VARCHAR2,
   oname           IN    VARCHAR2,
   { column_list   IN    VARCHAR2
   | column_table  IN    DBMS_UTILITY.NAME_ARRAY | DBMS_UTILITY.LNAME_ARRAY } );

Note:

This procedure is overloaded. The column_list and column_table parameters are mutually exclusive.

Parameters

Table 18-128 SET_COLUMNS Procedure Parameters

Parameter Description
sname

Schema in which the table is located.

oname

Name of the table.

column_list

A comma-delimited list of the columns in the table that you want to use as a primary key. There must be no spaces between entries.

column_table

Instead of a list, you can use a PL/SQL index-by table of type DBMS_UTILITY.NAME_ARRAY or DBMS_UTILITY.LNAME_ARRAY to contain the column names. The first column name should be at position 1, the second at position 2, and so on.

Use DBMS_UTILITY.LNAME_ARRAY if any column name is greater than or equal to 30 bytes, which might occur when you specify the attributes of column objects.


Exceptions

Table 18-129 SET_COLUMNS Procedure Exceptions

Exception Description
nonmasterdef

At least one column is not in the table.

notquiesced

Replication group is not quiescing or quiesced.



SPECIFY_NEW_MASTERS Procedure

This procedure specifies the master sites you intend to add to an existing replication group without quiescing the group. This procedure must be run at the master definition site of the specified master group.

If necessary, this procedure creates an extension_id that tracks the process of adding new master sites to a master group. You use this extension_id in the other procedures that you run at various stages in the process. You can view information about the extension_id in the DBA_REPSITES_NEW and DBA_REPEXTENSIONS data dictionary views.

This procedure adds the new master sites to the DBA_REPSITES_NEW data dictionary view for the specified replication group. This procedure can be run any number of times for a given replication group. If it is run more than once, then it replaces any masters in the local DBA_REPSITES_NEW data dictionary view for the specified replication group with the masters specified in the master_list/master_table parameters.

You must run this procedure before you run the ADD_NEW_MASTERS procedure. No new master sites are added to the master group until you run the ADD_NEW_MASTERS procedure.

See Also:

Syntax


DBMS_REPCAT.SPECIFY_NEW_MASTERS (
   gname           IN   VARCHAR2,

UNDO_ADD_NEW_MASTERS_REQUEST Procedure

This procedure undoes all of the changes made by the SPECIFY_NEW_MASTERS and ADD_NEW_MASTERS procedures for a specified extension_id.

This procedure is executed at one master site, which can be the master definition site, and it only affects that master site. If you run this procedure at one master site affected by the request, you must run it at all new and existing master sites affected by the request. You can query the DBA_REPSITES_NEW data dictionary view to see the new master sites affected by the extension_id. This data dictionary view also lists the replication group name, and you must run this procedure at all existing master sites in the replication group.

Caution:

This procedure is not normally called. Use this procedure only if the adding new masters without quiesce operation cannot proceed at one or more master sites. Run this procedure after you have already run the SPECIFY_NEW_MASTERS and ADD_NEW_MASTERS procedures, but before you have run the RESUME_PROPAGATION_TO_MDEF and PREPARE_INSTANTIATED_MASTER procedures.

Do not run this procedure after you have run either RESUME_PROPAGATION_TO_MDEF or PREPARE_INSTANTIATED_MASTER for a particular extension_id.

Syntax

DBMS_REPCAT.UNDO_ADD_NEW_MASTERS_REQUEST (
   extension_id   IN  RAW,

   error_msg_table     OUT DBMS_UTILITY.UNCL_ARRAY,
   error_num_table     OUT DBMS_UTILITY.NUMBER_ARRAY )
  RETURN BINARY_INTEGER;

Note:

This function is overloaded. The return value of VALIDATE is the number of errors found. The function's OUT parameter returns any errors that are found. In the first interface function shown under "Syntax", the error_table consists of an array of records. Each record has a VARCHAR2 and a NUMBER in it. The string field contains the error message, and the number field contains the Oracle error number.

The second interface function shown under "Syntax" is similar except that there are two OUT arrays: a VARCHAR2 array with the error messages and a NUMBER array with the error numbers.

Parameters

Table 18-140 VALIDATE Function Parameters

Parameter Description
gname

Name of the master group to validate.

check_genflags

Check whether all the objects in the group are generated. This must be done at the master definition site only.

check_valid_objs

Check that the underlying objects for objects in the group valid. This must be done at the master definition site only. The master definition site goes to all other sites and checks that the underlying objects are valid. The validity of the objects is checked within the schema of the connected user.

check_links_sched

Check whether the links are scheduled for execution. This should be invoked at each master site.

check_links

Check whether the connected user (repadmin), as well as the propagator, have correct links for replication to work properly. Checks that the links exist in the database and are accessible. This should be invoked at each master site.

error_table

Returns the messages and numbers of all errors that are found.

error_msg_table

Returns the messages of all errors that are found.

error_num_table

Returns the numbers of all errors that are found.


Exceptions

Table 18-141 VALIDATE Function Exceptions

Exception Description
missingdblink

Database link does not exist in the schema of the replication propagator or has not been scheduled. Ensure that the database link exists in the database, is accessible, and is scheduled for execution.

dblinkmismatch

Database link name at the local node does not match the global name of the database that the link accesses. Ensure that the GLOBAL_NAMES initialization parameter is set to TRUE and the link name matches the global name.

dblinkuidmismatch

User name of the replication administration user at the local node and the user name at the node corresponding to the database link are not the same. Advanced Replication expects the two users to be the same. Ensure that the user identification of the replication administration user at the local node and the user identification at the node corresponding to the database link are the same.

objectnotgenerated

Object has not been generated at other master sites or is still being generated. Ensure that the object is generated by calling GENERATE_REPLICATION_SUPPORT and DO_DEFERRED_REPCAT_ADMIN for the object at the master definition site.


Usage Notes

The return value of VALIDATE is the number of errors found. The function's OUT parameter returns any errors that are found. In the first interface function, the error_table consists of an array of records. Each record has a VARCHAR2 and a NUMBER in it. The string field contains the error message and the number field contains the Oracle error number.

The second interface is similar except that there are two OUT arrays. A VARCHAR2 array with the error messages and a NUMBER array with the error numbers.
