PH61827: TRYING TO START MULTIPLE SUBSCRIPTIONS USING THE STRTSMIR COMMAND MAY RESULT IN NOT ALL STARTING ON THE FIRST ATTEMPT.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Using the STRTSMIR command to start multiple subscriptions at
  once by specifying a wildcard character or the ALL keyword
  for the subscription name may result in some subscriptions
  
  not starting on the first attempt if a significant number
  of the subscriptions are directed to the same target system,
  
  the multiple requests will cause the target engine to run out
  of
  
  resources. In such a situation, the source engine issues
  
  the messages, CHC6455E from the CMO task and message CHC9694W
  
  will be issued by the SCT task, several minutes after the
  
  CHC0220I message for the same subscription's SCT task is seen.
  

Local fix

• Reduce the number of subscriptions for the same IIDR target to
  be started at the same time
