IT18189: THE STRMQM COMMAND CAN FAIL WITH REASON 545284880

APAR status

• Closed as program error.

Error description

• On systems which use INETD to start the MQ listener process
  amqcrsta a timing window exists which can cause the strmqm
  command to fail if an instance of the amqcrsta (INETD MQ
  listener) is started at the same moment.
  
  For example,
  
  $ strmqm MQINETD
  WebSphere MQ queue manager 'MQINETD' starting.
  The queue manager is associated with installation
  'Installation6'.
  The queue manager ended for reason 545284880, ''.
  rc=xecE_E_SUBPOOL_EXISTS
  
  The INETD listener program will fail MQCONNX ended with reason
  code 2538. (rc=MQRC_HOST_NOT_AVAILABLE)
  

Local fix

• Issue the strmqm command again.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of WebSphere MQ starting queue managers while MQ network
  utilities such as the INETD amqcrsta program are active or
  starting.
  This issue can also occur with the more commonly used listener
  runmqlsr program
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A timing window existed such that initialization of the main
  queue manager process could be affected by concurrent
  initialization of MQ network processes such as amqcrsta and
  runmqlsr. This caused the main queue manager execution control
  process (amqzxma0) to terminate incorrectly.
  

Problem conclusion

• The MQ initialization process has been modified to allow the
  execution control process  to correctly handle concurrent access
  from MQ network processes.
