RE: Legato oracle module.

Ron

        Yeah, technically you must perform an incremental level 0 before you can perform the other incremental backups. I think that is what you meant, but I think I saw somewhere that if you have done a complete backup but didn't run it as an incremental level 0, then RMAN won't let you do the other incremental backups.

        Keep in mind that RMAN only backs up used blocks, so your backup to disk will be smaller than your production database file sizes.

        The resource that helped me the most is the book "Oracle Backup & Recovery 101" by Smith and Haisley. He takes you step-by-step through creating some small practice databases and then executing the RMAN commands. About half the book is RMAN.

Dennis,
 Thanks for your comments.
 I have just received the new 36 GIG drives for the Alpha system and I plan to back the database up to disk and then during the day copy the backups to tape for archival purposes.
  I tried to use OEM RMAN backup on my test box to play-and-learn but it does not have the software for the tape manager. Disk space is also scarce on the test box so I can't do a database backup with RMAN until I install a new 60 GIG drive.
 If I understand the RMAN manuals, a "database" backup is needed before you do the incremental. I need the new disk space to do a database backup. It's been a lot of fun making do with what you have and learning to grovel and plead.
Thanks,
Ron

Ron - Couple of points for you to consider:

• If you only have a single Oracle server, you may want to consider using the control file to store the RMAN information.
• Ideally, you will have another system with licensed Oracle to host your RMAN catalog.
• You can host your RMAN catalog in a separate instance on the same server, but you should carefully examine the devices used by each instance so you don't have a single point of failure. You don't want your production instance failure to wipe out your RMAN instance.
• If you only have one production server, and don't plan future expansions, RMAN may be more trouble than it is worth. Its greatest benefit is at sites with many, many instances/servers.
• You might want to consider using RMAN to write to disk as Sujatha suggested so you only have one thing to learn at a time. That was the advice I was given. Dennis Williams DBA Lifetouch, Inc. dwilliams_at_lifetouch.com
