Prepare and using the API-crossing exit

 

The sample exit is supplied in source form only. To use the sample exit, or an exit program that you have written, create a load library, as you would for any other CICS program, as described in topic Building CICS applications.

If you use the default CICS program definitions supplied, the exit program CSQCAPX is installed in a disabled state. This is because using the exit program can produce a significant reduction in performance.

To activate the API-crossing exit temporarily:

  1. Issue the command CEMT S PROGRAM(CSQCAPX) ENABLED from the CICS master terminal.

  2. Run the CKQC transaction, and use option 3 in the Connection pull-down to alter the status of the API-crossing exit to Enabled.

If you want to run WebSphere MQ for z/OS with the API-crossing exit permanently enabled, with CICS Transaction Server for OS/390 and CICS for MVS/ESA, do one of the following:

In both cases reinstall the group. We can do this by cold-starting your CICS system or by using the CICS CEDA transaction to reinstall the group while CICS is running.

Using CEDA might cause an error if any of the entries in the group are currently in use.
