Rearchitecting High Availability Solution

edited Nov 4, 2009 12:50AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 4 commentsAnswered ✓
I currently have a primary and physical standby at one location and 2 additional physical standbys at another physical location.  All are 11gR1 on RHEL.  I do not currently have the data guard broker configured, nor do I have Enterprise Manager Grid control.
My failover time is about 7 minutes and switchover just seconds. UPgrade requires db shutdown.

What is the best upgrade plan or rearchitect solution to make this an extrememly high available system?

Things I'm looking at:
1. Configuring the broker for fast start failover
2. Enable flashback database so I can perform rolling upgrades using a transient logical standby.


Howdy, Stranger!
