We are now going to create some skip rules on the logical standby database in order to skip replication of DDL or DML operations on some tables. Then we'll see how to query the existing skip rules and finally the method for disabling the rules.
We need to create skip rules for tables and schemas, but first we need to stop SQL Apply using the following query:
SQL> ALTER DATABASE STOP LOGICAL STANDBY APPLY;
Then, the following statement will create a
skiprule to skip changes caused by DML statements on theEMPtable of theSCOTTschema. Execute the following statement on the logical standby database:SQL> EXECUTE DBMS_LOGSTDBY.SKIP(STMT => 'DML', SCHEMA_NAME => 'SCOTT', OBJECT_NAME => 'EMP'); PL/SQL procedure successfully completed.
If we also want skip DDL statements encountered for this table, the following statement will create another
skiprule:SQL> EXECUTE DBMS_LOGSTDBY.SKIP(STMT => 'SCHEMA_DDL'...
