| Can anyone recommend a decent Oracle v9.2 database backup and recovery software solution that is positioned in the niche between RMAN on the low-end and BMC's SQL backTrack on the high-end. Back-Track is so grossly expensive, and RMAN is so, well, gross. :-) Any opinions and/or hands-on experience would be appreciated. Thank you. |

| What kind of backup, tape or disk? What storage vendor for tape and/or tape management products? What server environment? Once you get to 9.x there is really no good reason at all to not learn and use rman. There are just too many good features and it actually works! Yes it is different, very. But gross is kind of strong. BMC is losing marketshare back to oracle with just rman ... it's that good. Time to start learning it, sorry if that's not the advice you wanted to hear. |

There is nothing wrong with RMAN of which I am aware. What, specifically, is your problem? Why should your company spend thousands of dollars because you can't or won't open OEM? -- Daniel A.

| Thank you for your helpful reply, I appreciate it. May I ask you more about using RMAN, since I have concerns about using and maintaining it. Oracle Metalink seems to regularly issue patches/fixes for RMAN. Since RMAN is within $ORACLE_HOME do you need to shutdown Oracle in order to applyand relink software fixes? How often do you do apply fixes and how much work/time does it take you to review the patches and stage them through your system landscape? How many separate installs of Oracle do you need to maintain for RMAN? How many Catalog databases (RCAT) do you use? Where are they hosted, on the same or on different server from the target database? Do the Catalogs ever get corrupt or have other problems that complicate the use of RMAN. Do you need to have separate Catalogs for separate version of Oracle? Do you use a naming convention to distinguish these to make then easier to manage? If RMAN aborts for any reason do you have to deal with manually cleaning up processes, enqueues, etc? How are you notified of an RMAN failure. How often do you use RMAN to restore a database to another server and rename the SID? Have you done a PITR using RMAN and many archives? How did you manage the disk space requires of the archive directory during that process? And lastly, thank you for not making some asshole assumption that I would spend my company's money because I can't or won't open OEM. Thank you. |

How many separate installs of > Oracle do you need to maintain for RMAN? Yes, but not because of RMAN. Almost never, since I wait for a more mature release.

How are you notified of an RMAN > failure. Look at logs. I wrote a prototype script to ignore "usual" errors in logs, but don't use it because I have so little reason to look at the logs I would quickly forget what to look for, so I need the practice. I also have email notification if other things go wrong. Typically, the things are: tape didn't work (I do RMAN to disk, then copy to tape, because tape drives are pos. They ocassionally become disassociated with their device, but that's not RMAN's fault.), out of disk space (someone ignored warnings), and there were a few ORA-4030's or whatever when first bringing it into use, quickly resolved searching metalink. > > How often do you use RMAN to restore a database to another server and > rename the SID?

Every few months (using RMAN to generate standby or new clone). That was easy to script, too, cookbooks on metalink. Haven't got around to a PITR with RMAN yet, but I put effort into avoiding situations where I have to use it (besides, http://www.dizwell.com/html/pitr_alternatives.html ). After many years of home-grown and Velpuri scripts, and I once saw a real screwup with Omniback/DLT's, I must say, RMAN is the way to go. After all, recovery is more important than backup. http://metalink.oracle.com/metalink/...abase _id=NOT > > And lastly, thank you for not making some asshole assumption that I > would spend my company's money because I can't or won't open OEM. I don't use OEM with RMAN, since I'm a unix/command line scripting bigot for repetitive production procedures. I reserve the right to make any asshole assumption that does not conflict with postings. jg -- @home.com is bogus. http://story.news.yahoo.com/news?tmp...m/tech_ebay_dc |

Someone (Joel?) appears to have put out some good answers to your questions already. Think about buying the RMAN book written by Robert Freeman, and read it several times. Start slowly and do some experimentation on a test system first. It will not seem so weird after a while! |

I am coping with about 60 separate Oracle installs on Unix for databases approaching 3TB in size. Today on Metalink this RMAN technote was updated: 247611.1. How did you get notified of that today? Will you be reviewing that and updating your RMAN software immediately? How do you know the RMAN you are running is reliable? The note lists numerous problems with RMAN. I manage a very small team of DBAs and I can not imagine committing DBA resources to them remaining vigilant for the almost constant RMAN fixes/problems, and yet still be accountable to Upper Management to provide a stable, mature backup/recovery tool for mission-critical databases. RMAN is too iffy for me. And its Total Cost Of Ownership seems high. Also, the frequent downtime it would take to maintain it precludes its use in a very large environment with 24x7 databases sized in TBs. I just don't have the DBA Staff it would take to acquire, apply, test, deploy RMAN fixes across every Oracle installed, then to search the internet for whatever scripts might be available to enable RMAN's use. This is mainly why I want to avoid RMAN and look for a separate out-of-the-box solution. You told me you are using RMAN for your backup/recovery solution, yet you have not tried a PITR with it yet. I could not get away with that. I appreciate your reply to my posting, though. C |

| Well, you won't appreciate this one. Are you, like, stupid or something? All of those things in Note: 247611.1 are fixed or easily worked around by 9206. Don't you realize a third party solution will have worse problems? If your management is prone to finger-point won't having another vendor involved hurt? And what about when your vendor gets bought by Sybase? Don't you realize anything other than RMAN will have worse problems? Didn't you notice the link to PITR workarounds? Haven't you read about how RMAN is the only solution that can avoid split-block issues? What are you doing now that you think is better? Have you searched metalink for BMC? Do you think it is a bad thing that Oracle is upfront about bugs? Do you think a product doesn't have bugs because it doesn't have patches? Do you really think there is any out-of-the-box solution? There is a whole industry of "integrators" based on making these things work. Where in the world did you get a high TCO for RMAN? Why would you search the internet for scripts? They're right there in the fine manual, just a few lines long! Sorry to make it rude or personal, but that's what I see. I'll wager you have management that thinks yelling at vendors and staff makes things get fixed. And it sounds like they haven't sprung for the proper number of 9's if they have too small staff and no way to perform periodic maintenance. jg -- @home.com is bogus. The crooks are getting smarter. http://www.signonsandiego.com/uniont...5identity.html |
