Problem summary

• ****************************************************************
  * USERS AFFECTED:  WebSphere Application Server V8.0 users of  *
  *                  EJB timers                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: The findEJBTimers and cancelEJBTimers   *
  *                      commands do not work on z/OS.           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The findEJBTimers and cancelEJBTimers commands use MBean
  operations to communicate with the server.  On z/OS, the the
  MBean operation is forwarded from the control region to the
  servant region, the timer info objects are serialized in the
  servant region, deserialized in the control region,
  re-serialized in the control region, and deserialized by the
  commands.  While re-serializing in the control region, the
  timer info object attempts to reconstitute data by accessing
  the scheduler service, which fails because the scheduler
  service does not start in the control region.
  

Problem conclusion

• The timer info objects have been updated to directly
  re-serialize the deserialized data in the control region rather
  than attempting to reconstitute it.
  
  APAR PM46159 is currently targeted for inclusion in
  Service Level (Fix Pack) 8.0.0.2 of WebSphere
  Application Server.
