For ASE: Primary database initialization (command pdb_init) will verify that the database will be configured with the command sp_reptostandby pdb, ALL. This will automatically mark all tables for replication, as well as all DDL commands.
For Oracle: The individual tables to be replicated must be marked, either explicitly using the pdb_setreptable command, or automatically during ra_init processing when configuration parameter pdb_automark_tables is set to true. By default, Mirror Replication Agent is configured to automatically mark all user tables during initialization.
Tables, stored procedures, and sequences must be marked for replication and have replication enabled for the object (table, stored procedure, or sequence). LOB columns must have replication enabled, and the table that contains the LOB column must be marked for replication and have replication enabled for that table.
There are five types of objects that can be marked for replication in a primary database:
Tables
Stored procedures
Large-object (LOB) columns
Database Definition Language (DDL)
Sequences (Oracle only)
