Step 14a. Change the CA Dispatch CVKEY

The default CA Dispatch storage protection key can be changed to do the following:

• Improve storage protection for shared storage used for communication between CA Dispatch and external tasks
• To specify a system key to operate CA Dispatch in z/OS systems that are using the ALLOWUSERKEYCSA(NO) option.

Member DSINSVC or ADSJSVC in CAI.CADSJCL provides a user modification to update the CA Dispatch SVC routine with the new CVKEY. After applying the user modification, update and apply PPT entries that direct z/OS to run CA Dispatch jobs in the storage protection key specified by CVKEY.

To install the CA Dispatch SVC outside of SMP/E and link into a separate load library, use member ADSJSVC in CAI.CADSJCL. Customize the ADSJSVC source code the same as you would for DSINSVC.
