Re: Can you select a Different RMAN backup for DUPLICATE?

Niall, when you're specifying the SET UNTIL clause in a run {} block like this;

run {
set until time|scn;
restore database;
recover database;
}

rman will automatically pick the right backup to be able to get to that point in time.

http://download-uk.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta065.htm#i1000331 says it quite clearly:

"untilClause
<http://download-uk.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta065.htm#i1000331>Specifies an end time, SCN, or log sequence number for a subsequent RESTORE<http://download-uk.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta051.htm#i85188>or RECOVER<http://download-uk.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta044.htm#i84135>command."

Cheers

Stefan
