Replication Agent Objects

Replication Agent creates objects in the primary database to assist with replication tasks.

There are two variables in Replication Agent database object names:

prefix – represents the one- to three-character string value of the pdb_xlog_prefix parameter (the default is ra_).
xxx – represents an alphanumeric counter, a string of characters that is (or may be) added to a database object name to make that name unique in the database.

The value of the pdb_xlog_prefix parameter is the prefix string used in all Replication Agent object names, except rs_marker and rs_dump.

The value of the pdb_xlog_prefix_chars parameter is a list of the nonalphanumeric characters allowed in the prefix string specified by pdb_xlog_prefix. This list of allowed characters is database-specific. For example, the only nonalphanumeric characters allowed in a database object name are the $, #, and _ characters.

Use the pdb_xlog command to view the names of Replication Agent transaction log components in the primary database.

See the Replication Agent Administration Guide for details on setting up object names.

To find the names of the objects created, at the Replication Agent administration port, invoke the pdb_xlog command with no keywords:

pdb_xlog

The pdb_xlog command returns a list of all the Replication Agent objects.
