I searched the manuals for TUNWSCC0 and found nothing. I tried searching the support site. I selected Mainframe Application Tuner as the product and entered TUNWSCC0 as the search argument. I got a response of "Product details are not found for this product, please return to the product information main page and select a valid product. "
I have not gotten the CICS or DB2 teams involved in doing their part as I had that 0C4 issue which is closed.
Release : 12.0
Component : CA MAINFRAME APPLICATION TUNER
