Error description

  • Java Management Extensions (JMX) specification tools such as
    "JConsole" permit an application to connect to a running JVM,
    for example to permit the JVM to be monitored.
    
    It is not possible to attach these JMX tools to an IBM MQ
    Managed File Transfer agent JVM.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of IBM MQ Managed File Transfer who
    want to attach monitoring tools to their agent JVMs.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    It was not possible to attach a JVM monitoring JMX tools such as
    JConsole to a IBM MQ Managed File Transfer agent's JVM.
    
    This was because attaching was disabled due to a problem within
    the JRE, which was documented under APAR IZ73533:
    
      http://www.ibm.com/support/docview.wss?uid=isg1IZ73533
    
    IBM MQ now ships a version of the JRE which contains this JRE
    APAR, so the attach feature can be re-enabled.
    

Problem conclusion

  • It is now possible to attach a JVM monitoring tool such as
    JConsole to a IBM MQ Managed File Transfer agent JVM, if the
    platform is using an IBM JRE (AIX, Linux, IBM i, Windows, z/OS).
     To enable this, set the environment variable BFG_ALLOW_ATTACH
    to some value in the shell which starts the agent - for
    instance:
    
      BFG_ALLOW_ATTACH=true
    
    After starting the agent in a shell where this environment
    variable has been set, JMX monitoring tools can then be attached
    to the agent's JVM, unless this function has been separately
    disabled in the JVM configuration.
    
    If running on a UNIX type platform, this variable will need to
    be exported in order to be picked up by the agent start scripts,
    eg:
    
      export BFG_ALLOW_ATTACH=true
