Managing and monitoring your CICS workload

This learning path provides an overview of the CICS® and z/OS® components, and some separate tools, which you can use for workload management and performance monitoring of your CICS regions. The primary audience for the learning path is CICS system administrators, and anyone who is involved with managing or assessing the performance of a CICS system.

Workload management is the process of defining performance goals for the items of work in a system (such as a z/OS sysplex or a CICSplex), and using a workload manager (such as z/OS Workload Manager) to adjust resource allocations or work routing in the system in order to meet those performance goals.

Monitoring is the process of collecting and reporting data about the items of work in a system. Monitoring data provides information which workload managers can use to make their decisions. You can analyze monitoring data reports to choose or adjust performance goals for the system, tackle any performance problems through tuning activities, and make decisions about your future strategy and investments.

This learning path introduces these workload management and monitoring tools, explains how they are related to each other, and provides links to more resources about them:
