IT42462: CRDATE and CRTIME fields of the SYSTEM.DEFAULT.SUB object are set to blank vales

APAR status

• Closed as program error.

Error description

• The create date and create time fields are set to blank values
  for the
  SYSTEM.DEFAULT.SUB object, for example:

Local fix

• The strmqm -c command can be used to redefine the
  SYSTEM.DEFAULT.SUB object:
  
  https://www.ibm.com/docs/en/ibm-mq/9.2?topic=reference-strmqm-st
  art-queue-manager
  
  This will restore the CRDATE and CRTIME fields.
  
  This workaround should be used with caution as it will also
  redefine
  all other IBM MQ system objects.  Any changes that had been made
  to the default values of the system objects  are overwritten by
  this
  command.   The dmpmqcfg command can be used before running
  the strmqm -c command to allow any user modification of the
  system objects to be reinstated.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users who redefine the SYSTEM.DEFAULT.SUB object will be
  affected by this issue.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The SYSTEM.DEFAULT.SUB object is processed differently to other
  subscription objects when it is redefined because it is the base
  template object.  This difference in processing caused IBM MQ to
  fail to preserve the CRDATE and CRTIME of the SYSTEM.DEFAULT.SUB
  object when that object is redefined.
  

Problem conclusion

• The code has been corrected so that the CRDATE and CRTIME fields
  are now preserved when redefining the SYSTEM.DEFAULT.SUB object.
