OEM + RMAN to clone from previous backup to development instance
We use ASM and RMAN from OEM for our backups, restores, and clones. We have a requirement to restore from a three-week-old backup of production to a dev instance. Although we have far more backups than the one needed, RMAN fails to recover the dev database whether we use a timestamp or an SCN number. All attempts fail with either RMAN-06555 or 06556 (datafile 1 must be restored form backup created before (date or time)). Crosscheck of the backup files appears to be working correctly. Does anyone have any idea why RMAN is not handling this correctly?
This same procedure works if the clone is from the "last backup."
