Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After a shared receiver channel fails, because the CHIN and
  QMGR is terminated, shared channel recovery attempts to restart
  the shared channel by another CHINIT in the QSG, but it
  receives message:
  
  +CSQX479E CSQ1 CSQXRESP Channel yyyyyyy.CSQG.00 is active on
                active on CSQ2, shared channel adoption failed.

  A shared receiver channel was running on a chinit which
  subsequently terminated.
  The channel was restarted and attempted to connect to a chinit
  that was still active. This detected the orphaned shared status
  entry and attempted to adopt the channel. rriAdoptSharedMCA
  checked the user data for the stopped chinit to determine if the
  channel could still be running on the owning chinit, however an
  error in this check caused it to incorrectly determine the
  channel could be running.
  As a result the adoption process attempted to send the stopped
  chinit a message requesting it end the channel. As the original
  chinit was still not running no response was received for this
  request, and channel adoption failed.
  

Problem conclusion

• Channel adoption processing has been changed to correctly check
  the state of the qmgr and chinit where the channel was running
  previously, ensuring that a message to kill the channel is sent
  if the owning qmgr/chinit are running and able to process the
  message.
