Re: RAC 10.2.0.3

another scenario,
all,

this oracle config 10.2.0.3 RAC on HP-UX B.11.11

we will try use cluster_interconnects parameter. since in this cluster configuration we have 2 databases.

so we put 3 private network
1 for clusterware (existing)
1 for 1st database
1 for 2nd database

how can this alleviate my problem?
i heard cluster_interconnects could not do failover/failback??

regards
ujang
