Hi-

I am using 9.2.0.7 standard edition for primary as well as standby databases. Every time when I complete the recovery and start the standby DB I have observed something different in the alert log. Here is some part from my alert log.

Any one have idea why the Oracle signeling ALTER SYSTEM SET job_queue_process .... command and try to open the database even before I mount the standby database? Any help much appreciated.

Thanks,
