To replicate transactions that affect the data in a table in the primary database, that table must be marked for replication, and replication must be enabled for the marked table.
Marking a table can be separate from enabling replication for that table. If the value of the pdb_dflt_object_repl parameter is true, replication is enabled automatically at the time a table is marked. For more information, see “Enabling and disabling replication for marked tables”.
By default, Mirror Replication Agent will mark and enable
user tables and their LOB columns for replication when the Mirror
Replication Agent is initialized using the ra_init command.If
this is not the default behavior desired, you can turn off automatic
marking of tables using the pdb_automark_tables configuration
parameter.
When a table is marked for replication, the Mirror Replication Agent does the following:
Connects to the RASD
Records the mark status for the table in the RASD Article for that table.
When a table is marked and enabled, any subsequent operations that affect the data in that table are replicated.
When you unmark a table marked for replication, the Mirror Replication Agent does the following:
Connects to the RASD
Records the unmark status for the table in the RASD Article for that table
When a table is unmarked, any subsequent operations that affect the data in that table are ignored (not replicated).
