APAR status

  • Closed as program error.

Error description

  • Error Message: When running the heapdump command in jdmpview
    against a z/OS core dump the user received the message "ERROR:
    Couldn't get handle on current process"
    .
    Stack Trace: N/A
    .
    

Local fix

  • The original core dump can be used in the same way as a heap
    dump by many tools, for example Memory Analyzer.
    

Problem summary

  • The heapdump command in sdk/bin/jdmpview would always attempt to
    generate a heap dump only for the first address space found in
    the dump, even if that address space did not contain a JVM or
    there were multiple address spaces that contained JVMs.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR1
    .
    The heapdump command in the jdmpview tool has been changed to
    scan all address spaces for JVMs and write out a heap dump for
    each JVM found.
    .
    To obtain the fix:
    Install build 20110817 or later
    

Temporary fix
