Applies to:Oracle Containers for J2EE - Version 10.1.3.0.0 to 10.1.3.5.0 [Release AS10gR3]
Information in this document applies to any platform.
When the load increases as more users are accessing the application, OC4J performance slows down leading to different timeout errors. These errors can be found in following files:
- OPMN log file : default_group~<oc4j instance>~default_group~1.log
Furthermore following information indicates this problem:
- OC4J thread dump shows large number (200+) of threads idle and waiting on socket read even when there are only 20 or fewer number of requests
- Running "netstat -an|grep <ajp port>" shows large number of sockets on "TIME_WAIT"
Also setting the OC4J startup option -Dajp.keepalive=true for the specific oc4j instance does not help.
