R12.1.3 : Login page hangs frequently
Hi,
We have a non-prod instance cloned from Production. We are able to login / navigate html pages / open forms . However, frequently the login page fails to come up. The only solution we have is to bounce the middle tier to resolve the issue. We have not been able to identify the root cause for this problem.
There are no messages in oacore. In Apache error logs , we find the following
[Tue Nov 8 10:39:32 2016] [error] [client 10.30.147.218] [ecid: 1478619572:10.131.64.10:24971:0:752,0] mod_oc4j: Failed to find a failover oc4j process for session request for destination: application://oacore (no island or jgroup).
