DBMS_REPCAT: Managing Snapshot Replication Groups
Although most of the procedures in the DBMS_REPCAT package are used to create and maintain the advanced replication environment, some of the procedures let you manipulate snapshot replication groups. This section describes only the snapshot-related programs. The bulk of the DBMS_REPCAT programs are described in Chapters 15 and 16.
The procedures in DBMS_REPCAT used for manipulating snapshot replication groups are in large measure analogous to the procedures DBMS_REFRESH provides for manipulating simple snapshot groups.
Getting Started with DBMS_REPCAT
The DBMS_REPCAT package is created when the Oracle database is installed. The dbmsrepc.sql script (found in the built-in packages source directory, as described in Chapter 1) contains the source code for this package’s specification. This script is called by catrep.sql, which must be run to install the advanced replication packages. The script creates the public synonym DBMS_REPCAT. The package procedure DBMS_REPCAT_AUTH.GRANT_SURROGATE_REPCAT grants EXECUTE privileges on the package to the specified grantee. In addition, the package owner (SYS) and users with the EXECUTE ANY PROCEDURE system privilege may execute it.
DBMS_REPCAT programs
Table 14.5 lists only the DBMS_REPCAT snapshot-related programs; see Tables 15-3 and 16-10 for the remaining DBMS_REPCAT programs.
