Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who experience a hang on the MQ Appliance, and need to
    send some debugging information to IBM.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    No command existed to collect call stacks from hanging
    processes.
    

Problem conclusion

  • The command amqxdbg -k has been added to collect call stacks,
    for sending to IBM.
    
    The output will be written to a new file under mqerr:
    To see these files from the command line, type these two
    commands.
    - config
    - dir mqerr:
    
    Alternatively, use the IBM MQ Appliance web UI to access the
    mqerr: filesystem
