Monitoring security messages

Some security-relevant events, such as incorrect sign-on attempts, cause a message in the QSYSOPR message queue. You can also create a separate message queue called QSYSMSG in the QSYS library.

If you create the QSYSMSG message queue in the QSYS library, messages about critical system events are sent to that message queue as well as to QSYSOPR. The QSYSMSG message queue can be monitored separately by a program or a system operator. This provides additional protection of your system resources. Critical system messages in QSYSOPR are sometimes missed because of the volume of messages sent to that message queue.
