We have oracle standby (not active) database configured, and it is in mount mode. We are using F5 as the load balancer to switch between Primary and standby databases. When we route the application traffic through F5, then applications are seeing randomly "ORA-cannot safely recall". This issue doesn't happen when F5 is not in picture, meaning routing the traffic directly to the Oracle database server instead of through F5. I have opened an SR with Oracle and also a support ticket with F5. Oracle says it is happening only when F5 is in picture, and F5 support says the error returned is an Oracle error not F5 error. does any one have seen this kind of issue, if so please share what you did to resolve.
Thank You!
