sorry, folks, but I though as many production DBAs as are on this list, I might be able to get an answer to this question. What I need to know is how Oracle licensing works on a hot-standby (e.g., a VCS failover node). In this case I'm thinking that the failover node will never be running oracle *unless* the primary is dead. Seems like a single system worht of CPUs to license in my mind...any feedback ? >-----Original Message----- >From: oracle-l-bounce@xxxxxxxxxxxxx >[mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Ron Rogers >Sent: Tuesday, June 21, 2005 10:27 AM >To: jrsmiley@xxxxxxxxx; richard.ignizio@xxxxxxxxxx; >rgramolini@xxxxxxxxxxxxxxx >Cc: oracle-l@xxxxxxxxxxxxx >Subject: RE: RMAN backups > >Ruth, > You are correct. a level 0 backup for me takes 14 min at 10.4 >Gig disk used and the level1 backups takes 14 min at 3.7 Gig. >Ron > >>>> "Ruth Gramolini" <rgramolini@xxxxxxxxxxxxxxx> 06/21/05 1:05 PM >>> >John, > >Unless something has changed with 10g, and incremental backup >doesn't actually save much time.
