- Oracle AS 10.1.3 connecting to Database 10.2.0.2 with 2 firewalls (firewall high availability) in between them
- 3 AS servers --> 2 HA firewall -> Fail safe DB (2 - on windows 2003 cluster)
- 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
- 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.
