Client Net Service configuration for RAC & Data Guard

edited Aug 3, 2009 10:22AM in Database Networking (MOSC) 5 commentsAnswered
I have a two-node RAC production database and one physical standby. I'm having difficulties configuring a client-side net service (tnsnames.ora) to support load balance and failover for an instance failure (failover to another instance in RAC) and site failure using DGMGRL without manual intervention (failover to standby)
I cant specify "FAILOVER=ON" in the net service entry, as this conflicts with the way DGMGRL performs switchovers/failovers (you need GLOBAL_DBNAME set in the listener for DGMGRL, but "a statically configured global database name disables connect-time failover.")

Does anyone know how I can achieve a RAC configuration with both instance and site failover, in a way that still allows DGMGRL to work correctly?

Howdy, Stranger!
