Tuning a sysplex

The performance of systems in a sysplex is closely related to the performance of the signaling service. The throughput and responsiveness of the systems participating in the sysplex depend on the signaling service. Therefore, it is important to be able to identify and correct performance problems that are related to signaling. This information describes considerations for tuning the signaling service and illustrates how you can use RMF reports to do tuning and capacity planning for the signaling service.

It is also important to perform capacity planning so that the signaling service is able to adequately meet the needs of its users, and thereby provide good signaling performance as workloads change over time.

The performance of the coupling facility in the sysplex also affects overall sysplex performance, especially if you are using the coupling facility for signaling.
