PH67216: CSQX514E - CHANNEL FAILING TO ADOPT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• rriAdoptMCA calls rrxStopChannel, it passes it the status entry
  in a handle. rrxStopChannel checks the ChanSeqNo, but
  rriAdoptMCA passes an incorrect sequence number in the handle.
  This results in rriAdoptMCA thinking that the channel has been
  stopped, when it hasn't been.
  

Local fix

• Stop the receiver channel with MODE(FORCE) STATUS(INACTIVE).
  Then start the sender channel.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *
  *                 Release 4 Modification 0.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: Running channels cannot be adopted by a *
  *                      newer instance, and any other attempt   *
  *                      to do so will fail with CSQX514E.       *
  ****************************************************************
  The code which handles the channel adoption tries to stop the
  running instance with an uninitialised sequence number in the
  handle, which results in the channel not being stopped. The
  incoming channel will then continue to wait for the running
  channel to stop. As there is already one channel waiting for the
  running instance to end, if another channel attempts to adopt
  it, it will fail with CSQX514E.
  

Problem conclusion

• The code has been changed to set the sequence number in the
  handle to the Channel Status's sequence number before attempting
  to stop the channel with rrxStopChannel.
