Issue/Introduction

Introduction: 

The AllowUserKeyCSA parameter was introduced in z/OS V1.8 to prevent jobs from allocating storage from Common Storage Areas subpools using user keys 8 through 15. It can be set to AllowUserKeyCSA(YES) or AllowUserKeyCSA(NO). User key CSA creates a security risk because any unauthorized program can modify it.

 At z/OS 1.8 the default was ALLOWUSERKEYCSA(YES) for compatibility. Starting at V1.9, the default is AllowUserKeyCSA(NO).

Question: 

How does parameter << ALLOWUSERKEYCSA>> affects CA Endevor SCM?

Environment:  

z/OS V1.8 and higher

Answer: 

Endevor does not use CSA storage for its processing, so setting of ALLOWUSERKEYCSA to either yes or no has no effect on Endevor.
