IZUW950I The MSO service coefficient is greater than 0.0000. You might be able to set the coefficient equal to the recommended value of 0.0000.

Explanation

					z/OS Workload Manager (WLM) uses service
					coefficients when calculating the amount of service
					(MSO, SRB, IOC, and CPU) that a service class period
					has consumed. When a service class period has
					consumed the amount of service specified by its
					duration, WLM switches the workload to the goals of
					a lower period.

					Assigning a coefficient to the MSO service that is
					greater than 0.0000, even a coefficient as small as
					0.0001, can result in a very large number of MSO
					service units for a workload that is consuming a
					large amount of storage. The large MSO service units
					might cause WLM to switch the workload to a lower
					service class period and thus impact the performance
					of the workload.

System programmer response
No action is required.

User response
				To ensure that a workload that occupies a large amount
				of storage is not switched to a lower period, set the
				coefficient for the MSO service to 0.0000. Decrease the
				durations of multi-period service classes that consume
				MSO service units, as needed.

					If your installation uses MSO service units for
					accounting or billing purposes, be sure to assess
					how changing the coefficient impacts those purposes.
