Question:

We are nearly ready to upgrade to z/OS 2.1 and are being asked to "turn off" the default userid ahead of the actual switch from 1.13 to 2.1. Is there a best suggested way to comply with this request?

Answer:

To turn off the OMVSUSR and OMVSGRP control options: 

TSS MODI OMVSUSR() 

TSS MODI OMVSGRP() 

Be sure to also remove the control options from the CA Top Secret parameter file.
