Hi all,
We have an 11.2.0.1 database which is about 2T in size, and generates 700k of
redo per second. We're running on Sun/Oracle SPARC 64-bit - v10.
Any estimates as to how long an RMAN incremental level-0 (full) backup might
take to run - say when backed-up to a local mount and/or to an NFS mount?
Right now, we're allocating 8 channels.
Also - has anyone experienced a significant decrease in RMAN backup I/O
throughput after upgrading from 10g to 11g - resulting in backups taking 2-3x
longer than before the upgrade? If so, any suggestions?
Thanks for your help.
