15 DBMS_OFFLINE_OG

The DBMS_OFFLINE_OG package contains public APIs for offline instantiation of master groups.

This chapter contains this topic:

Note:

These procedures are used in performing an offline instantiation of a master table in a multimaster replication environment.

These procedure should not be confused with the procedures in the DBMS_REPCAT_INSTANTIATE package (used for instantiating a deployment template). See the documentation for this package for more information about its use.

Subprogram Description

"BEGIN_INSTANTIATION Procedure"

Completes offline instantiation of a master group.

"END_LOAD Procedure"

"RESUME_SUBSET_OF_MASTERS Procedure"

BEGIN_INSTANTIATION Procedure

This procedure starts offline instantiation of a master group. You must call this procedure from the master definition site.

END_INSTANTIATION Procedure

This procedure completes offline instantiation of a master group. You must call this procedure from the master definition site.

Note:

This procedure is used to perform an offline instantiation of a master table in a multimaster replication environment.

This procedure should not be confused with the procedures in the DBMS_REPCAT_INSTANTIATE package (used for instantiating a deployment template). See the documentation for this package for more information about its use.

See Also:

"Adding New Master Sites with Offline Instantiation Using Export/Import" for information about adding a new master site to a master group by performing an offline instantiation of a master site

Syntax

  gname     IN  VARCHAR2,
  new_site  IN  VARCHAR2);

Parameters

Table 15-6 END_INSTANTIATION Procedure Parameters

Parameter Description

The fully qualified database name of the new site to which you are replicating the replication group.


Exceptions

Exception Description
badargument

NULL or empty string for replication group or new master site name.

dbms_repcat.nonmasterdef

This procedure must be called from the master definition site.

unknownsite

Specified site is not recognized by replication group.

wrongstate

Status of master definition site must be quiesced.

dbms_repcat.missingrepgroup

RESUME_SUBSET_OF_MASTERS Procedure

When you add a new master site to a master group by performing an offline instantiation of a master site, it might take some time to complete the offline instantiation process. This procedure resumes replication activity at all existing sites, except the new site, during offline instantiation of a master group. You typically execute this procedure after executing the DBMS_OFFLINE_OG.BEGIN_INSTANTIATION procedure. You must call this procedure from the master definition site.

Note:

This procedure is used to perform an offline instantiation of a master table in a multimaster replication environment.

This procedure should not be confused with the procedures in the DBMS_REPCAT_INSTANTIATE package (used for instantiating a deployment template). See the documentation for this package for more information about its use.

See Also:

"Adding New Master Sites with Offline Instantiation Using Export/Import" for information about adding a new master site to a master group by performing an offline instantiation of a master site

Syntax

DBMS_OFFLINE_OG.RESUME_SUBSET_OF_MASTERS (
   gname     IN  VARCHAR2,
   new_site  IN  VARCHAR2
   override  IN  BOOLEAN := FALSE);

Parameters

Table 15-10 RESUME_SUBSET_OF_MASTERS Procedure Parameters

Parameter Description
gname

Name of the replication group that you are replicating to the new site.

new_site

The fully qualified database name of the new site to which you are replicating the replication group.

override

If this is TRUE, then any pending administrative requests are ignored and normal replication activity is restored at each master as quickly as possible. The override parameter should be set to TRUE only in emergency situations.

If this is FALSE, then normal replication activity is restored at each master only when there is no pending administrative request for gname at that master.


Exceptions

Table 15-11 RESUME_SUBSET_OF_MASTERS Procedure Exceptions

Exception Description
badargument

NULL or empty string for replication group or new master site name.

dbms_repcat.nonmasterdef

This procedure must be called from the master definition site.

unknownsite

Specified site is not recognized by replication group.

wrongstate

Status of master definition site must be quiesced.

dbms_repcat.missingrepgroup

gname does not exist as a master group.
