IT22390: Incorrect thread ID reported in application activity trace for asynchronous worker

APAR status

• Closed as program error.

Error description

• When running an application activity trace of an application
  which handles an asynchronous MQ callback, such as the amqscbf
  sample, the activity trace reports an incorrect thread ID.
  
  The same error may be seen in the thread ID passed to an API
  exit for an asynchronous callback.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of MQ V8 and later using application activity trace or API
  exits with applications using asynchronous callback routines.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A logic error in the queue manager routines for recording
  application activity trace and invoking API exits meant that an
  incorrect thread ID was recorded when reporting asynchronous
  callback routine invocation.
  

Problem conclusion

• The MQ product has been modified to set the correct thread id in
  API exits and application activity trace when used by
  asynchronous callback routines.
