I don't think you mentioned the version of Oracle you're on, but did you try this? exec dbms_logstdby.skip('SCHEMA_DDL','SYSMAN','%',null); exec dbms_logstdby.skip('DML','SYSMAN','%',null); This is what I used in 10.1.0.3 (now 10.1.0.5) for each schema that I did not want to be included in the replication scheme.
