PI14674: ELIMINATE NEED FOR -AGENTLIB:HEAPDETECT PARAMETER ON SERVER JVM.

Subscribe

You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • The -agentlib:HeapDetect is missing from the server.xml
    because defaultXD is not in the list of templates in the
    console. This can cause HeapDetect to not work properly, which
    adversely impacts Memory Overload Protection.
    

Local fix

  • Manually add -agentlib:HeapDetect parameter to JVMs which were
    created with default template.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V8.5                                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: Cannot start a WebShpere Application    *
    *                      Server due to missing the HeapDetect    *
    *                      attribute on invocation.                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    On starting a WebSphere Application server at version 8.5 and
    above, it requires the attribute -agentlib:HeapDetect on
    the command line.  Since this attribute does note exist in
    some conditions, the server cannot be started.
    

Problem conclusion

  • The native code is updated to automatically pick up the
    correct level of the class without requiring the attribute
    agentlib:HeapDetect.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.2.  Please refer to the Recommended Updates
