IBM® MQ for z/OS system considerations
The z/OS® system is an area that requires examination when investigating performance problems.
You might already be aware that your z/OS system is under stress because these problems affect many subsystems and applications.
You can use the standard monitoring tools such as Resource Monitoring Facility ( RMF ) to monitor and diagnose these problems. They might include:
- Constraints on storage (paging)
- Constraints on processor cycles
- Constraints on DASD
- Channel path usage
Use normal z/OS tuning techniques to resolve these problems.
