I'm running Oracle 9i, and trying to create a database-level trigger after startup. Database name is DKDB. Here is the beginning of the trigger code:

CREATE TRIGGER PurgeOnStartup
AFTER STARTUP ON DKDB

And here is the error:

AFTER STARTUP ON DKDB
*
ERROR at line 2:
ORA-30506: system triggers cannot be based on tables or views

I have not created any tables or views named DKDB. I'm logged in with DBA privs. I've already logged in as sys and ran dbmsstdx.sql, What am I doing wrong?

Thanks!
