When did SOURCE START become the default?
Release : 3.2
Component : CA VM:Secure for z/VM
VM:Secure solution RO94110 (dated Feb. 2017) is the enhancement PTF that made SOURCE START the default.
This was an enhancement to disable the quick startup of VM:Secure using the online directory in order to reduce complexity and increase reliability. The system will now create at startup a new online directory structure using the source statements in its database.
