Hi Friends

I am doing different recovery scenarios on my testing server and i have one problem which is described below.I have two archive destinations one is mandatory and another is optional. at the time of recovery process it finds one archive file is corrupted and the recovery process is canceled even recovery option is auto. as i understand if archival file of the one location is corrupted, then its automatically use the second set of archive file from different location. if my understanding is proper, then in which case the above recovery behavior possible.can any body help me to understand it.

Regards
Chintan

Failover between multiplexed archivelogs is automatic if you use RMAN, not if you use SQL*Plus.

Not possible. Look in the alert log for that period, and you'll see what happened.

No guidance, because you have not been telling the truth. In your second post, you claimed to have done recovery successfully. But the alert log shows that you didn't. It is hard to advise someone who obfuscates reality.
You had better start again, with a fresh set of tests.

Dear John

I apologized for that post. I was paste the alert log for more clarity. I was done recovery for so many times and that is the only reason of some misunderstanding. my aim is not to hide truth. i know that misleading information harm to me only.

Thanks
Chintan
