IT21147: Permit monitoring of IBM MFT agent JVM's using JMX tools such asJConsole

APAR status

• Closed as new function.

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
