RE: RMAN - questions.. Rob Freeman?
Thanks Dennis... Ya.. its all on disk and problably only a test with some tuning is going to give me realistic picture. I am going to try it on NETAPPS new disaster recovery SAN solution Brian Spears -Original Message- Sent: Wednesday, February 05, 2003 3:50 PM To: Multiple recipients of list ORACLE-L Brian - Hopefully Robert will have a chance to respond to your question, but if I might make some suggestions, I think your recovery time has two components: 1. If the backup files are not on disk, the time to locate the tape, load the files. 2. RMAN recovery time. I think you will just have to perform some tests on your equipment. There are several tunable RMAN parameters that will make a great deal of difference (or not), depending on your hardware. There are many different types of recovery. Some recoveries may require very little data from RMAN, others may require a lot. You need to outline (and eventually test) for the different types of recovery scenarios. Overall, my experience has been that RMAN offers very fast performance, usually limited just by disk speeds. But what impresses me may not meet your needs. I'm easily impressed.

RE: RMAN - questions.. Rob Freeman?
I am considering doing an rman to disk backup and recovery solution for a 500G-- grow to 1terabyte database. Monster HP servers ... up t0 16 cpu, upto 10,000 concurrent users This rman would be the secondary recovery solution (Timefinder is the first). Anybody know time frames I might be able to restore/backup 500Gig to 1terabyte of database from disk? I will perform it before it goes live but I would like get a ball park idea of restore times before hand so we can determine if it can fit in the SLA requirements. Any parameters to focus on to improve performance other than allocating channels?

You will only know what your system is capable of It is very dependant on the disk arrays and no of scsi or fibre channels you have to support those disks Also RAID level will be a big contributor How long does it take to copy say a 500MB file from location to location. check it out this way. see what throughput you are reporting in sar or glance or similar Test this between the filesystem your db is on and where you want to put the backup to disk -- = Peter McLarty E-mail: [EMAIL PROTECTED] Technical ConsultantWWW: http://www.mincom.com APAC Technical Services Phone: +61 (0)7 3303 3461 Brisbane, AustraliaMobile: +61 (0)402 094 238 Facsimile: +61 (0)7 3303 3048 = A great pleasure in life is doing what people say you cannot do. - Walter Bagehot (1826-1877 British Economist) = Mincom The People, The Experience, The Vision = This transmission is for the intended addressee only and is confidential information.

RE: RMAN - questions.. Rob Freeman?
Brian - Hopefully Robert will have a chance to respond to your question, but if I might make some suggestions, I think your recovery time has two components: 1. If the backup files are not on disk, the time to locate the tape, load the files. 2. RMAN recovery time. I think you will just have to perform some tests on your equipment. There are several tunable RMAN parameters that will make a great deal of difference (or not), depending on your hardware. There are many different types of recovery. Some recoveries may require very little data from RMAN, others may require a lot. You need to outline (and eventually test) for the different types of recovery scenarios. Overall, my experience has been that RMAN offers very fast performance, usually limited just by disk speeds. But what impresses me may not meet your needs. I'm easily impressed.

RE: RMAN - questions.. Rob Freeman?
Is this all live OLTP type data, or might some of the data be made read-only? How much will the data be growing and changing (if not a great deal then look into incrementals). I can't begin to guess at the time required those numbers are all factors of: 1. # of backup devices you will be backing up to (I'd suggest several, minimum of probably 6). 2. Speed of backup devices. 3. Speed of infrastructure from DB to the backup devices. Given a best case, lots of backup devices to backup to in parallel, fast fast infrastructure and really fast (and expensive) equipment, you could backup 1TB in an hour or two... Realisticly, much much longer, perhaps upwards of 10-12+ hours at a moderate price range. You could stagger these backups over the week, backup some tablespaces and all archived redo logs on day one, other tablespaces and archived redo logs on day two and so on. This staggered approach will reduce the overhead associated with a large, long lasting backup. Recovery of a TB will take a while of course, be prepared for that when negotiating your SLA's. A product like BMC's timefinder makes a good primary backup/recovery solution. -Original Message- To: Multiple recipients of list ORACLE-L Sent: 2/5/2003 2:16 PM I am considering doing an rman to disk backup and recovery solution for a 500G-- grow to 1terabyte database.
