Re: RMAN recovery question...

Dianna,

Your scripts look correct and no changes are required.

If you are on version 10gR2, you dont need to create temp tablespace explicitly after the complete restore, oracle creates them automatically for you. If you are not on 10gR2, then, you need to create temp tbs manually.

What about channels, can I allocate
more channels for a faster recovery?

more channesl are not for faster recovery, it depends on how many tape drives with the backup library, rather, you may use parallel with recovery to have parallel recovery.

And this may be a stupid question,
but if more-current files are there, is RMAN intelligent enough to just restore the changed blocks? It was a full on-line backup. And depending on the answer, should I delete all the old files or can I just leave them as is?

I once did recovery where after restoring some files, rman got terminated due to time out with the thrid party tool we use for backup to tape and when I strat restore again, oracle was intelligent enough to bypass them as saying they are already on the disk and continue restoring furthe datafiles.

I would also suggest you couple of things, like make sure your backups are valid, without restoring probably, RETORE VALIDATE DATABASE and you can also test how much time they gonna take, using, RESTORE DATABSE TEST (please correct me I am wrong with this command).
