z/OS system considerations

You might already be aware that your z/OS system is under stress because these problems impact many subsystems and applications.

We can use the standard monitoring tools such as Resource Monitoring Facility (RMF) to monitor and diagnose these problems. They might include the following:

• Constraints on storage (paging)

• Constraints on CPU cycles

• Constraints on DASD

• Channel path usage

Use normal z/OS tuning techniques to resolve these problems.
