Re: RMAN need for alter system archive log all
Rather than copy the archive logs to tape, do an archivelog backup using rman. Archive the current log when you start. Then you can put all the backupsets, database and archivelog, on one tape and rman will know just what he needs to recover a database.

RE: RMAN need for alter system archive log all
H ya know, maybe it is a new feature in 9i. I went and tried it because I was thinking that it did do the log switch, but I just wasn't 100% sure... I did it in 9iR2 (backup archivelog all) and it does do the log switch (it even says in the output, switching current log, and I also had logfiles generated in the archive log destination. I was the only one on the system, so I know it wasn't a chance switch. Still, maybe in 8i it doesn't. I'll try it on 8i and see if it's different. Robert G.

In the 9iR2 documentation for RMAN is clearly states that during backups using the PLUS ARCHIVELOG command, RMAN does force a log switch. When you do a backup using the PLUS ARCHIVELOG command RMAN will: Run ALTER SYSTEM ARCHIVE LOG CURRENT Runs the BACKUP ARCHIVELOG ALL command. Backs up the files specified in the BACKUP command. Run ALTER SYSTEM ARCHIVE LOG CURRENT again. Back up any remaining archived redo logs. A normal backup of archived redo logs such as BACKUP ARCHIVELOG ALL will not result in a log switch. Robert G.

At least. I've not seen it. In my archive Rman database backups, I issue an 'alter system archive log current' before I backup the archive files to make sure that I have the latest archive I can possible get. Unless I'm convinced that Rman is doing this for me, I have no reason to change my procedures. You could certainly include this command both within an Rman script or elsewhere to make sure that you get the same benefit. Hope this helps.

Someone on this list provided that advice as start simple. I was using RMAN to store the archive logs, but that just used up twice the disk space and I could discern no benefit so I stopped it (always open to new reasons). On recovery, RMAN uses the original archive logs just fine. I just want to make sure we have the right archive logs on tape, and this morning I posted an update to my original question, namely that I found where RMAN automatically issues an ALTER SYSTEM ARCHIVE LOG CURRENT. I'm a little confused about the timestamp on the archive logs, but I guess I just have to take it on faith that Oracle and RMAN are doing the right thing. Thanks Ruth.

Archive the current log when you start. Then you can put all the backupsets, database and archivelog, on one tape and rman will know just what he needs to recover a database. Ruth - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Monday, September 23, 2002 5:43 PM 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.
