For most commands, it does not matter whether you issue them from within the primary database or the proxy database; only the primary database is updated. However, the following list describes the commands that you cannot issue from within the proxy database:
create or drop procedure
create or drop view
create or drop trigger
create or drop rule
create or drop default
You must run dump and load database commands from the primary companion. If you issue these commands from the proxy database, they will only update the proxy database; they will not update the primary companion.
