pdb_xlog_prefix

The prefix string used in database object names to identify Replication Agent transaction log objects.

Note: This parameter has been deprecated. Use the ra_admin_instance_prefix parameter instead.

Default

ra_

A character string of 1 to 3 characters.

When Replication Agent generates database object names for transaction log components in the primary database, it uses the value of the pdb_xlog_prefix parameter as an object name prefix.
Replication Agent uses the value of the pdb_xlog_prefix parameter to recognize its transaction log objects in the primary database. Therefore, if you change the value of the pdb_xlog_prefix parameter after the transaction log objects are created, Replication Agent will not be able to find its transaction log objects.
The value of the pdb_xlog_prefix_chars parameter specifies the non-alphabetic characters that can be used in the prefix string.
