In order to be aware of what will and will not be replicated, we should check which primary database tables are not supported for the logical standby database.

  1. Run the following query on the primary database to see the unsupported table names:

    SQL> SELECT * FROM DBA_LOGSTDBY_UNSUPPORTED_TABLE ORDER BY OWNER,TABLE_NAME;
    
    OWNER      TABLE_NAME
