z/OS CICS

There are several activities you can do with the CICS Execution Option that you have installed on your z/OS CICS environment.

You can:

Test your CICS Execution Option installation by running the sample maps provided in the installation.
Use the CICS Execution Option to run your maps.

Note: The IBM Transformation Extender includes the CICS Execution Option through which you can run maps in your CICS environments. Prior to IBM Transformation Extender version 8.1, this functionality was provided in the CICS Command Server product.

Running the map examples
After successfully installing the software, you can run the map examples included in the installation to test the installation to ensure the CICS Execution Option is functioning properly.
Using the CICS Execution Option
The CICS Execution Option can be invoked in several ways.
z/OS CICS execution commands
Specifying storage medium
The z/OS CICS Execution Option can map from or to any of six different storage media.
Using EXEC CICS LINK passing storage buffers
When the z/OS CICS Execution Option is called by an EXEC CICS LINK, it is often because you want to pass to the CICS Execution Option the address of one or more storage buffers containing input data or the address of one or more storage buffers that will contain mapped output data or both address types.
Using the EXIT function
The EXIT function is available when entering mapping rules for fields using the Map Designer on your PC.
Using the RUN function
Preloading IBM Transformation Extender maps and .mdq files in a z/OS CICS environment
The CICS® preloader utility preloads IBM Transformation Extender maps and database query (.mdq) files into memory. When maps and .mdq files run frequently, you can reduce processing by preloading them into memory. Preloaded files do not require I/O processing.
Abnormal termination
If a task terminates abnormally with an internal error, the return code 16 and an error message are passed back to the calling program.
The DTXMPULD utility
In addition to loading maps into the KSDS, where maps are stored for use in the z/OS CICS region as described above, the DTXMPULD utility has the capability of listing and deleting maps from the KSDS map.
