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.
