try "set until time"

generally speaking, the validate procedure does test the incrementals,
assuming they are required to bring your database to a current state. It
should start with the last level 0 and then go thru all the subsequent 0+n
incrementals to validate your restore.

Subject: RMAN physical backup verification - incrementals


We run a weekly incr level 0 and daily incr 1 backups via RMAN.  I'd like to
verify that whatever we write to tape is good; normally I'd do this by
requesting a restore to test it.

Rman has a nice 'validate' feature that I tried to take advantage of via
something like this:

        connect target;
        run {
                allocate channel c1 type sbt;
                restore database validate;
        }

This works, but I noticed that it always requests a restore of the last INCR
0
backup -- even if several days since then have passed.  How do others verify
that their INCR backups > 0 are cleanly written to tape?

Thanks!
Rich
