Duplication Fails with Multiple RMAN-06023 Errors: Diagnosis

The DUPLICATE command recovers to archived redo logs, but cannot recover into online redo logs. Thus, if the restored backup cannot be made consistent without applying the online redo logs, then duplication fails with RMAN-06023 errors because RMAN is looking for backups created before the most recent archived log.

Duplication Fails with Multiple RMAN-06023 Errors: Solution

After backing up the source database, archive and back up the current redo log:

RMAN> SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
RMAN> BACKUP ARCHIVELOG ALL;
