Limiting Repetitive Messages

A WTO buffer shortage can occur on a z/OS system when, for example, a program loops while issuing messages. You can use the MSGFILTER parameter on the SETOPTION command to limit the number of identical messages that CA MIC routes cross-system.

To set a limit, specify an integer from 1 to 1000 on the MSGFILTER parameter or OFF. When a user issues this number of consecutive messages with the same message ID, CA MIC stops routing that message cross-system after the next message is issued. CA MIC resets its counter when it processes a different message from the same user or a message from a different user.

The default value for the MSGFILTER parameter is 50.
