Weblogic multisource config. with Metro Cluster and RAC

[RonVanCleave]

Hello,

Has anyone ever tried configuring Weblogic Multi-Sources to connect and failover with 2 RAC running in a Metro Cluster?

Unable to identify a recipe that allows WebLogic to failover when the Metro-Cluster fails over from RAC-1 to RAC-2, where RAC-2 is a passive node in the package.

Each RAC has 2 Oracle nodes, so we have
RAC-1 node-R1a,node-R1b
RAC-2 node-R2a,node-R2b

We are able to configure the Weblogic Multi-Source to failover from node-R1a to node-R1b
when node-R1a fails.

We are unable to failover from node-R1a or node-R1b to node-R2a or node-R2b if RAC-1 fails over to RAC-2 with the Metro-Cluster.

If anybody has been successful with Weblogic and Oracle RAC in a Metro Cluster, if you could share your strategies that would be really appreciated.

Can share more specific/detailed tns, multi-source and connection pool configurations.

Regards, Ron
