Temporary data sets (work files)

The IBM® Transformation Extender under CICS® uses temporary data sets (work files) differently in CICS than in Batch.

When running IBM Transformation Extender maps, the following recommendation for using temporary data sets, might improve the performance of CICS applications running the IBM Transformation Extender under CICS:

• The CICS Execution Option uses a VSAM RRDS data set defined at product installation and configuration time for its workspace (temporary files) data set.
• Verify that the CSDSTRNO parameter correctly reflects the total number of DATAFILS configured plus the MAP KSDS in your system's environment. Incorrect settings can lead to string waits causing performance degradation.

  See z/OS CICS for detailed information about configuration requirements and options.
