Symptoms

Setup:

 

  1. During resilient test of firewall (firewall failover) the connection pool becomes invalid
    • Application is using Sticky Session
    • So on firewall failover end users loose their sessions
  2. For performance reasons applications (BPEL) need to maintain about 25 minimum connections in OC4J managed connection pool.


When application is not used for a while (for example not used overnight), the physical connection to Database through firewall is terminated by firewall timeout settings and the pooled connections becomes invalid.
