There are two variables in the Replication Agent object names shown in this chapter:
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 object 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 objects in the primary database. If you change the value
of pdb_xlog_prefix after you create
the Replication Agent objects, the Replication Agent instance will
not be able to find the objects that use the old prefix.
Use the pdb_xlog command to view the names of Replication Agent objects in the primary database.
See the Replication Agent Administration Guide for details on setting up replication object names.
