Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    User who is not QMQM or QMQMADM on client need to log errors
    when AMQERR01.LOG reaches the maximum size.
    
    
    Platforms affected:
    IBM iSeries
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When AMQERR01.LOG reaches the maximum size, attempt to log
    errors result in log rollover for AMQERR01.LOG. But MQ only
    allow user QMQM or QMQMADM on IBM i to do the log rollover. When
    the effective user is NOT QMQM or QMQMADM, a per user log
    AMQERR01.<user id>.LOG is created to log errors. MQ code make
    the owner of all MQ product created files as QMQM, so the client
    failed to log error to the per user log.
    

Problem conclusion

  • MQ code is changed to make the owner of the per user log as the
    effective user. Then non-QMQM or non-QMQMADM user could log
    errors to the per user log.
