One workaround might be to use a link, if that's feasible in your
environment - though I would be careful if we're talking about mucking
about in OH.

Subject: Re: RMAN testing
The problem is that the first run of the RMAN happens successfully and creates backup files in "/psoft/u02/...", but the second run looks for file in $OH/dbs (/psoft/u01). It is trying to recover files in OH/dbs. In the beginning (yesterday when I started testing) /psoft/u01 was where RMAN was doing the backup. I delete the old backups several times and rerun the RMAN. Somehow RMAN seems to want to restore in the original location of OH/dbs only in the second run.
Is there any command to tell RMAN not to look in OH/dbs while doing the restore in the second run? I run crosscheck after deleting backups.
RMAN *second* run looking for files in OH/dbs (/psoft/u01...) :

It might have to do with your saved configuration. Try a "show all"
to see what is set, and then you can run a "CLEAR", like you did for
the SBT_TAPE setting, for the setting(s) that you want to reset.
