Suppress information messages

Your IBM MQ system might produce a large number of information messages. We can prevent selected messages being sent to the console or to the hardcopy log.

If your IBM MQ system is heavily used, with many channels stopping and starting, a large number of information messages are sent to the z/OS console and hardcopy log. The IBM MQ - IMS bridge and buffer manager might also produce a large number of information messages.

If required, we can suppress some of these console messages by using the z/OS message processing facility list, specified by the MPFLSTxx members of SYS1.PARMLIB. The messages you specify still appear on the hardcopy log, but not on the console.

Sample thlqual.SCSQPROC(CSQ4MPFL) shows suggested settings for MPFLSTxx. See the MVS Initialization and Tuning Reference manual for more information about MPFLSTxx.

If you want to suppress selected information messages on the hardcopy log, we can use the z/OS installation exit IEAVMXIT. We can set the following bit switches ON for the required messages:

  2. You are not recommended to suppress messages other than those in the suggested suppression list, CSQ4MPFL.
In addition we can specify the extra parameter:
