F5 Big IP for App Failover between Oracle Data Guarded Clusters

Hi Bill,

 

 

I thought RAC should provide seemless failover between cluster nodes. Are you trying to handle the scenario where the complete cluster goes down?

 

 

It would be good if someone here with more experience with Oracle commented as well, but in concept, I think you could configure a single pool with two groups of members. You could use priority group activation to ensure application requests go to the higher priority group first. If that group isn't available the lower priority members would be used. You could configure an Oracle DB monitor to check if the pool members are up.

 

 

If you want LTM to send a reset to the client if the selected pool member goes down, you can configure this using the 'Action On Service Down' down option in the pool properties.
