All objects created in the primary database to support replication are prefixed with a common value, identified by configuration property pdb_xlog_prefix:
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 Mirror Replication Agent object names.
The value of the pdb_xlog_prefix_chars parameter is a list of the non-alphanumeric characters allowed in the prefix string specified by pdb_xlog_prefix. This list of allowed characters is database-specific. For example, in Oracle, the only non-alphanumeric characters allowed in a database object name are the $, #, and _ characters.
To find the names of the objects created
At the Mirror Activator administration port, invoke the ra_helpsysinfo command with no keywords:
ra_helpsysinfo
The ra_helpsysinfo command returns a list of the transaction log base objects.
