RE: RMAN archive log - mystery deepens

Okay, I looked carefully at the RMAN report, and it automatically issues an

    alter system archive log current
(duh!)

Then I look at the three systems I backed up with RMAN last night. On two of the three, an archive log was produced 3 minutes before RMAN said it was completed. But on the largest system, there was an archive log timestamped 28 minutes prior and another 15 minutes after RMAN said it completed. Does this sound reasonable? Is it just if no changes had occurred maybe there was no current log to archive?

List - I am wrapping up my RMAN procedures so I can turn off conventional backups and still sleep at night. I am on Oracle 8.1.6. Does anyone know the answer to this question: If I do an RMAN backup to disk, then copy the RMAN backup pieces to tape, and copy the archive logs to tape, do I need to execute an ALTER SYSTEM ARCHIVE LOG ALL before I copy the archive logs to tape? This has been necessary for hot backups, but I can't recall this being mentioned specifically for RMAN. I want to be able to recover the database from the contents of the backup tape alone, and I noticed during my disaster recovery tests that you definitely needed to have required archive logs available.
