IBM prepares for the removal of support for user key common areas
I was presented with this PTF on our recent z/OS 2.2 Maintenance upgrade.
.
UA94606
.
The allocating, obtaining, or changing common areas of virtual
storage, such that the storage is in user key
(8-15), will not be supported after z/OS V2R3.
In addition, setting the DIAGxx parmlib statement
VSM ALLOWUSERKEYCSA to YES will not be supported after
z/OS V2R3. IBM strongly recommends specifying or
defaulting the ALLOWUSERKEYCSA statement to NO.
