Introduction:

Since Release 1.9 on z/OSĀ the CSA parameterĀ ALLOWUSERKEYCSA gives you the the ability to specify NO to stop allocation of user key CSA.

Question:

Does XCOM for z/OS has any issues with the setting ALLOWUSERKEYCSA(NO) in member DIAGxx of SYS1.PARMLIB?

Answer:

The ALLOWUSERKEYCSA parameter does not affect XCOM for z/OS, since XCOM does not allocate any storage in the CSA.
