Question:

We are currently running z/OS 2.1.  Do we still need the OMVS defaults at all in ACF2?  Should they be removed?

Answer:

The defaults are no longer looked at with z/OS 2.1 and above.  They can stay in ACF2 since they are not used.  But since auditors like clean systems, it might be bteer to remove them since they are defaults and may raise questions.
