MSGDRAINRATE Parameter

This parameter with the MSGTHRESHOLD parameter, detects address spaces that issue excessive numbers of messages. To understand what these parameters do, consider this analogy: each address space is like a bathtub with a depth set by MSGTHRESHOLD. Each time the address space issues a message, it flows into this bathtub, which has a drain through which the MSGDRAINRATE number of messages flows each second. When the message bathtub overflows, CA OPS/MVS issues message OPS4402O.

To prevent messages from overflowing an address space and causing system problems due to looping, you can create a message rule. This rule might cancel the looping address space or place it in a penalty performance group.

Default value

10 (messages)

Other possible values

Any number of messages between 1 and 32767

Set or modify this parameter…

Anytime

Example: MSGDRAINRATE
