E-business suite - 12.1.3 - 4 nodes(servers) in the cluster
DB - 11.2 - 4 nodes(servers) in RAC
How is correct to set up the listener for CONCURRENT SERVER in this situation?
As I see there are two common ways:
1. If we use the usual listener with loadbalancer it makes a huge contention between all RAC nodes for fnd_concurrent_requests table.
2. If I create a new listener with failover and at one time it looks to one RAC node only than all concurrent requests will work on ONE RAC node only? if it's so than it's not good because the concurrent server makes a lot of work and they are will not be executed on all nodes.
