IT22029: MQ install runs mqconfig script as root user, which may not provide appropriate feedback on configured user limits

APAR status

• Closed as program error.

Error description

• During an MQ installation the mqconfig script runs to display
  operating system limits which may need to be tuned for MQ to
  run properly.  Included in the mqconfig output are user limits
  for the root user, which may not be relevant to running MQ.
  .
    Current User Limits (root)
    nofile       (-Hn)  4096 files        IBM>=10240        FAIL
    nofile       (-Sn)  4096 files        IBM>=10240        FAIL
  

Local fix

• Ignore user limits reported for the root user.  Run the mqconfig
  script manually as the 'mqm' user, and as any other user in the
  mqm group who creates or starts queue managers, to ensure their
  user limits are sufficient for MQ.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users installing MQ
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The mqconfig tool analyzes and lists the user limits for the
  user who runs the command.  MQ installations run as the root
  user and hence the mqconfig script run as part of installation
  always analyzes the user limits for the root user. If the root
  user is not one of the MQ administrative users (members of mqm
  group) then the mqconfig analysis during the MQ installation
  might not be relevant. This had the potential to be misleading
  for customers during the installation
  

Problem conclusion

• The mqconfig script has been modified to display appropriate
  messages about the user whose configuration is being tested.
