External factors

External factors can greatly affect the overall performance of the IBM® Transformation Extender running under Batch or CICS® on the z/OS® operating environment and should be taken into account when assessing overall throughput and performance.

The following factors should be considered:

• Configuration of the operating system
• Work loads / Queue depths
• Work Load Manager policies and goals
• Batch-oriented scheduling issues relating to resource contentions or collisions, or both
• Transaction priorities

Some of these factors can significantly impact overall performance of the IBM Transformation Extender running under Batch or CICS on the z/OS operating environment, thereby requiring a more in-depth analysis or real-time tools to gather resource statistics to isolate and take corrective action.

Tools such as RMF (Resource Measurement Facility), in conjunction with SMF (System Management Facilities) records, help in monitoring and identifying any performance problems within traditional batch-oriented processing. Additionally, the CICS Performance Monitor can be used to identify performance problems within CICS environments.
