Understanding mainframe performance

An important step in trying to achieve performance improvements running the IBM® Transformation Extender under Batch and CICS® on the z/OS® operating environment is to understand the IBM Transformation Extender execution characteristics specific to these environments.

"General Performance" includes performance tips and information on what occurs during product execution when running the IBM Transformation Extender on all available platforms.

There are additional performance and execution characteristics specific to running the IBM Transformation Extender under Batch and CICS on z/OS environments that can greatly affect their overall performance, including:

• Hardware Expectations and MIPS/MSU Ratings
• File Formats
• Pre-allocating Work Files (Temporary Data Sets)
• Paging in Memory
• External Factors
