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 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 Microsoft SQL Server, the only non-alphanumeric characters allowed in a database object name are the $, #, @, and _ characters.
You can use the ra_helpsysinfo command to view the names of Mirror Replication Agent transaction log components in the primary database.
See the Mirror Activator Administration Guide for details on setting up log object names.
