Last updated on JUNE 02, 2023

Applies to:

Oracle Containers for J2EE - Version to [Release AS10gR3]
Information in this document applies to any platform.


When using admin_client.jar to undeploy then deploy an application,  the following error appears:

The issue can be reproduced with the following steps:
1. opmnctl stopall
2. opmnctl startall
3. Deploy an application to OC4J <INSTANCE1> which has 2 JVMs configured.
Deploy and undeploy an ejb application multiple times. The deployment will fail intermittently (can take a lot of tries sometimes)with a ClassNotFoundException .
4. Workaround: if we decrease numprocs of OC4J <INSTANCE1> to be 1 the above steps run successfully without ERROR.

Note: It has not been determined if the same reproduces using ASControl.
