Before you create the Replication Agent transaction log base objects, you can specify the object name prefix string that will be used to name all the transaction log objects.
The pdb_xlog_prefix configuration parameter stores the prefix string. Use the ra_config command to change the value of the pdb_xlog_prefix parameter.
When the pdb_xlog_prefix parameter is set to use the prefix string you want for the Replication Agent transaction log objects, you can use the pdb_xlog command to create the transaction log base objects in the primary database.
Replication Agent uses the value of pdb_xlog_prefix to
find its transaction log in the primary database. If you change
the value of pdb_xlog_prefix after you
create the transaction log, Replication Agent will not be able to find
the transaction log objects that use the old prefix.
