Troubleshoot IBM Developer Kit for Java

This topic shows you how to find job logs and collect data for Java™ program analysis. This topic also provides information about program temporary fixes (PTFs) and getting support for IBM^® Developer Kit for Java.

If the performance of your program degrades as it runs for a longer period of time, you may have erroneously coded a memory leak. You can use the JavaWatcher, a component of iSeries™ iDoctor, to help you debug your program and locate any memory leaks. For more information, see JavaWatcher.

• Limitations
  This list identifies any known limitations, restrictions, or unique behaviors in the IBM Developer Kit for Java.
• Find job logs for Java problem analysis
  Use the job log from the job that ran the Java command, and the batch immediate (BCI) job log where the Java program ran, to analyze causes of a Java failure. They both may contain important error information.
• Collect data for Java problem analysis
  To collect data for an authorized program analysis report (APAR), follow these steps.
• Apply program temporary fixes
  Beginning in i5/OS™ V5R4, you can use the Display Java Virtual Machine Jobs (DSPJVMJOB) CL command to manage your JVM jobs and apply PTFs while the system is active.
• Get support for the IBM Developer Kit for Java
  Support services for the IBM Developer Kit for Java are provided under the usual terms and conditions for iSeries software products. Support services include program services, voice support, and consulting services.
