I recently did the same thing<//www.freelists.org/post/oracle-l/Trying-to-wrap-my-head-around-TAF,4>. The trick is to create a database trigger that turns off the service for the standby database. For example: SQL> CREATE OR REPLACE TRIGGER manage_OCIservice after startup on database DECLARE role VARCHAR(30); BEGIN SELECT DATABASE_ROLE INTO role FROM V$DATABASE; IF role = 'PRIMARY' THEN DBMS_SERVICE.START_SERVICE('failover'); ELSE DBMS_SERVICE.STOP_SERVICE('failover'); END IF; END; Still waiting for Oracle to make this a bit more clear; sometimes the documentation stumbles over itself in being too verbose. =) I also had Oracle Support tell me that there were issues when you explicitly put the LOAD_BALANCE statement in there like that. But we never did figure out exactly what those "issues" were.
