There are two variables in the Replication Agent transaction log table names shown in this appendix:
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 table 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 transaction log table names.
If this value conflicts with the names of existing database objects in your primary database, you can change the value of the pdb_xlog_prefix parameter by using the ra_config command.
Replication Agent uses the value of pdb_xlog_prefix to
find its transaction log tables in the primary database. If you
change the value of pdb_xlog_prefix after
you create the Replication Agent transaction log, the Replication Agent instance
will not be able to find the transaction log tables that use the
old prefix.
You can use the pdb_xlog command to view the names of Replication Agent transaction log tables in the primary database.
