Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of the IBM MQ resource monitoring feature on a queue
  manager where PSMODE is set to COMPAT may be affected by this
  problem.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A shared memory set that is needed by the monitoring feature was
  not created unless the PSMODE parameter was set to ENABLED.
  This shared memory set should be created whether PSMODE is
  configured to be either ENABLED or COMPAT.
  

Problem conclusion

• The code has been changed so that the required shared memory set
  is created if PSMODE is set to ENABLED or COMPAT.
