Error description

  • <span style="font-size:12px">A </span><span
    style="font-size:12px">user who is not in the mqm group, but who
    has been granted appropriate MQ authority to create channels is
    not able to do so when running the runmqsc command locally to
    the queue manager. The command completes without any reported
    error, but the channel definition is not created.</span>
    
    <span style="font-size:12px">An IBM MQ diagnostic trace of the
    attempt to create a channel shows failure to access the qm.ini
    file.</span>
    

Local fix

  • Re-run the runmqsc command as a member of the "mqm" group, or
    issue the command using runmqsc in client mode (runmqsc -c).
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Non-mqm group users trying to create MQ channels running runmqsc
    locally to the queue manager.
    
    Running runmqsc in client mode with the -c switch in order to
    connect over a SVRCONN channel is unaffected by this issue, even
    if the connection is made to localhost.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Changes in MQ 9.2 meant that the qm.ini file was accessed during
    the creation of the channel object. If the runmqsc program was
    running with insufficient permissions to access the qm.ini file
    (ie. running as a user who was not a member of the mqm group),
    the access to the qm.ini file failed, which caused the channel
    creation to fail.
    

Problem conclusion

  • The fix allows users who have appropriate IBM MQ authorities to
    create a non-TLS channel when running runmqsc locally against
    the queue manager.
    
    
    
    If creating a TLS channel (SSLCIPH attribute set to a non-empty
    value) locally, the operation will fail with the following
    errors:
    
    Permission denied attempting to access an INI file.
    Permission denied attempting to access an INI file.
    AMQ8242E: SSLCIPH definition wrong.
    
    This inability to create TLS channels when running runmqsc as a
    local non-mqm group user is a product restriction and
    improvements to the documentation in this regard are covered by
    related APAR IT41324.
