There are two variables in the transaction log component database 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 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 Replication Agent object names.
The value of the pdb_xlog_prefix_chars parameter is a list of the nonalphanumeric characters allowed in the prefix string specified by pdb_xlog_prefix. This list of allowed characters is database-specific. For example, in Microsoft SQL Server, the only nonalphanumeric characters allowed in a database object name are the $, #, @, and _ characters.
Use the pdb_xlog command to view the names of Replication Agent transaction log components in the primary database.
See the Replication Agent Administration Guide for details on setting up log object names.
