The MYS/SP Version 2 JES2 and JES3 program products differ from their
counterpart MYS/SP Version 1 program products in that the former have been
modified as required to support System/370 extended architecture facilities, and
.._,
new availability, serviceability, and usability facilities have been added. Otherwise,
MYS/SP Version 2 offers the same facilities as the BCP and JES (JES2 or JES3)
components of MYS/SP Version 1 Release 3. MYS/SP Version 2
will
operate
only in processors with System/370 extended architecture implemented (4381,
308X, and 3090 processors).
The MVS/XA Data Facility Product program product provides data management,
device support, program library management, and utility functions. It supports
System/370 extended architecture facilities and includes the functions provided by
the following for MYS/SP Version 1:
•
Data Facility Device Support
•
Sequential Access Method-Extended
•
Data Facility /Extended Function
•
Offline IBM 3800 Utility
•
Access Method Services Cryptographic Option
3800 Enhancements and prerequisite program service
MVS/XA is designed to be compatible with MVS/370 as far as is possible.
User-written MYS System/370 mode programs that use published external
interfaces will operate under MVS/XA without modification, with minor
exceptions. In general, IBM-supplied MYS programs, products, and subsystems
will operate with MVS/370 or MVS/XA. MVS/370 and MVS/XA job control
and user data set formats are compatible and most MVS/370 operator messages
and commands are utilized as is in MVS/XA.
Assembler H Version 2 is provided to support System/370 extended architecture
(new operation codes, new channel command word format, specification of the
addressing to be used, etc.).
70:30 VM/Extended Architecture Migration Aid
The VM/Extended Architecture (VM/XA) Migration Aid is designed to execute
in all 4381 model groups operating in System/370-XA mode. Release 2 or later
supports 4381 Model Groups 11, 12, 13, and 14. Release 1 or later supports 4381
Model Groups 1, 2, and 3. This program product is designed for a DOS/VSE,
VSl, or MVS/370 user who wishes to migrate to MVS/XA and to execute
production work and MVS/XA testing using one 4381 system. The VM/XA
Migration Aid supports only a subset of the functions provided by the System/370
mode VM/370 programming system and its program products, but is extended to
support specific facilities for a combined MVS/370 production and MVS/XA
testing environment.
