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.

[EMAIL PROTECTED] -----Original Message----- Sent: Wednesday, February 05, 2003 2:16 PM To: Multiple recipients of list ORACLE-L 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? Thanks for any help Brian Spears -----Original Message----- Sent: Wednesday, February 05, 2003 9:53 AM To: Multiple recipients of list ORACLE-L Check out the doc's at tahiti.oracle.com and look up the parameter noprompt.
