Top Secret

Issue/Introduction

Is Top Secret r16.0 affected by this IBM APAR? The z/OS RSU2303 has the following Hold-Action 

OA61750: NEW FUNCTION - SUPPORT JES2 CHECKPOINT VERSIONS IN 64-BIT STORAGE (ibm.com)

This New function APAR moves JES2 checkpoint versions from 31-bit data space storage to 64-bit storage that will be owned by the JES2AUX address space. To request a checkpoint version in 64-bit storage, the user application must use a version 10 IAZDSERV parameter list. The pre-version 10 IAZDSERV parameter lists contain 31-bit pointers and therefore cannot be updated with 64-bit pointers. Any 64-bit pointer that cannot be set in a 31-bit format IAZDSERV will cause the associated 31-bit pointer field to be set to x'7FFFFBAD' 

Environment

Release : 16.0

Resolution

No impact on Top Secret 16.0. Top Secret does not make a request for checkpoint versions.
