Enterprise bean and EJB container troubleshooting tips
If you are having problems starting an EJB container, or encounter error messages or exceptions that are generated by an EJB container, follow these steps to resolve the problem:
- Use the admin console to verify that the application server which hosts the container is running.
- Browse the JVM log files for the application server which hosts the container. Look for the message server server_name
open for e-business in the SystemOut.log. If the message does not display, or if you see the message, problems occurred during startup, browse the SystemErr.log for details.
- Browse the system log files for the application server which hosts the container.
- Enable tracing for the EJB container component, by using the following trace specification EJBContainer=all=enabled. Follow the instructions for dumping and browsing the trace output to narrow the origin of the problem.
With WAS v8 you can configure the server to use the HPEL log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using $PROFILE/bin/LogViewer.sh.
If none of these steps solves the problem, check to see if the problem is identified and documented in the following topics: Diagnosing and fixing problems: Resources for learning. If you do not see a problem that resembles yours, or if the information provided does not solve your problem, contact IBM support for further assistance.
