We currently have a 3 node RAC dataguard setup running in max
performance mode with one 3 node RAC remote dg standby. We have
problems with the primary db hanging when too much redo is generated,
the bandwidth is not enough to keep up with it. We use lgwr(on the
remote mandatory dest.) in async mode with stanby redo logs on remote
side to get redo over asap. So we are thinking about getting another
large non-RAC server and San to mirror the primary db(currently on a
san) and stop using lgwr to send redo to remote site. Then we could
failover to local db when primary db goes down and since the san's
would be mirrored we could break the mirror and continue running on
local server db. My question is is there a way to continue running dg
on local db once it's manually failed over from primary. In other words
have the local db continue sending arch. logs to remote standby db? Any
insight is appreciated.
