Giri, As per my understanding from below communication Issue happens when forms conection switches from Machine A (working fine as long as you are connected to A ) to Machine B (Users who were connected to Instance B forms initially can access Instance B without Issues ). Please confirm if this is true Also confirm if two users User1 connected to server1(forms) & user2 connected to server2 (forms) can access forms services without any issues or not ..

Yes, I shutdown all the services on node to which I connected right now. Next time when I connected I am connect to the other surviving node. Then I am getting this error GET /OA_JAVA/oracle/apps/fnd /formsClient/FormsLauncher/class.class HTTP/1.1" 404 267 This issue is not specific to new cloned node. I am getting the same error when my session switches to surviving node (surviving node could be node 1 or node 2) or when I start a new session after closing existing session which was connected to failed node.
