Brief Description of Announcement, Charges, and Availability

     The VM/XA System Product (VM/XA SP) is IBM's premier VM
operating system for IBM 370-XA capable processors. VM/XA System
Product Release 1 supersedes all releases of VM/XA Systems Facility
(VM/XA SF) while providing a migration path for VM/XA  Systems
Facility customers.  All VM/XA Systems Facility functions are
supported including single-image N-way, vector processors,
partitionable expanded storage, and block paging.  In addition to
offering new function and additional device support to VM/XA Systems
Facility customers, it offers, for the first time in the XA
environment, an interactive environment capable of supporting large
numbers of users. It also provides a bimodal CMS which will operate
in either System/370 mode with 24-bit addressing or 370-XA mode with
24- or 31-bit addressing capability.  Additionally, program
interfaces have been defined to allow the development of applications
which are portable between System/370 and 370-XA CMS virtual
machines.  Virtual Machine/System Product High Performance Option
(VM/SP HPO) customers will find that VM/XA System Product Release 1
offers an attractive growth path to IBM's larger processors running
in single-image mode and relief to user growth constraints.

DESCRIPTION
       VM/XA System Product Release 1 licensed program incorporates
all the functions of VM/XA Systems Facility and offers enhanced
function and additional device support.
SUPPORT OF HIGH CAPACITY CMS WORKLOADS
       Support is provided for selected licensed programs new to the
VM/XA environment such as PROFS (TM) and enhancements have been made
to increase the number of interactive users that can be supported in
the VM/XA environment.  VM/XA System Product Release 1 provides
additional capacity for CMS environments over what is provided by
VM/SP HPO.
 (TM) Trademark of International Business Machines Corporation
BIMODAL CMS
       The VM/XA System Product Release 1 CMS, which is an extension
of the VM/System Product (VM/SP) Release 5 CMS, has been enhanced to
take advantage of the capabilities of 370-XA architecture including
31-bit addressability for both programs and data.
       This single CMS can execute on either System/370 or 370-XA
virtual machines.
       When CMS is invoked in 370-XA mode, applications may benefit
from 370-XA capabilities including 370-XA input/output (I/O)
capabilities and storage addressing for both programs and data above
the previous 16-megabyte addressing limit.  Engineering and
scientific users will benefit by the 31-bit capability of VS Fortran
Version 2 and the Engineering and Scientific Subroutine Library.
Applications that have not been enhanced to fully utilize the 31-bit
capability may execute and reference data below the 16-megabyte
addressing limit and still benefit from 370-XA I/O advantages.
Applications that cannot execute above the 16-megabyte limit may
co-exist with 370-XA capable applications.
       Programs running on CMS will now be able to take advantage of
370-XA virtual machine sizes that are greater than 16-megabyte.
       The enhancements to the CMS programming interfaces enable an
application to be coded so that it can be independent of whether it
is running in a System/370 virtual machine or a 370-XA virtual
machine. In addition, programs running in a 370-XA virtual machine
can choose to execute with either 24-bit addressing, 31-bit
addressing, or dynamically switch between the two.
       Some modifications may be required to migrate an application
to VM/XA System Product Release 1 due to the differences between
System/370 and 370-Extended Architecture.
PERFORMANCE MONITORING FACILITY
       A native VM monitoring facility, including significant
enhancements over prior VM/370 monitors, is provided in the VM/XA
System Product environment.  The monitor facility provides the
necessary data which will enable the user to analyze the utilization
of, and contention, for the major system resources such as
processors, storage, I/O devices and the paging subsystem.  Monitor
externals have been substantially revised, in order to permit future
system growth and meet user requirements.
VM/XA REAL TIME MONITOR SUPPORT
       VM/XA System Product Release 1 will provide support for VM/XA
Real Time Monitor/Systems Facility (RTM/SF). All support as provided
for RTM/SF on VM/XA Systems Facility Release 2 has been upgraded to
support VM/XA System Product Release 1.
LOGGED-ON USER LIMIT ENHANCEMENTS
       Function is provided to allow installations to limit the
maximum number of users logged onto the system.
RACF SUPPORT
       VM/XA System Product Release 1 provides customers with the
data security functions as provided in VM/SP (with or without VM/SP
HPO) ensuring compatibility to those customers who have implemented
RACF data security procedures on their current VM/SP systems.
ADDITIONAL DEVICE SUPPORT

COMPATIBILITY:
Compatibility Statement for VM/XA SF Release 2:
       In general, VM/XA System Product Release 1 is upward
compatible from VM/XA Systems Facility Release 2.
       Application programs that currently execute on VM/XA Systems
Facility should execute without change unless dependent on those
functions listed under exceptions, below.
       Programs written in higher level languages are source and
object level compatible on CMS (i.e., CMS supports the same languages
for both systems).
       Programs using 24-bit virtual storage addresses continue to
execute in virtual storage below 16 megabytes without change.
       Exceptions: Programs or EXECs that depend on one or more of
the following will need to be examined for compatibility:
o   Internal control program and CMS structure of control blocks
o   External
    -   Applications that use undocumented interfaces
    -   Programs that depend on the syntax or output format of
        control program commands.  The syntax of most command
        invocations remains upward compatible. The format of many
        command responses has changed, particularly for Query and
        SPOOLing commands.
    -   Programs that operate on SPOOL files owned by another user
        must now refer to SPOOL files by userid and spoolid. Control
        program SPOOLing commands are enhanced for this support.
o   Messages - There are a small percentage of messages where the
    text has been improved for clarity and consistency.
    Approximately half of the 370-XA messages have changed message
    numbers.  Return codes have also experienced extensive changes.
    Additionally, VM/XA SP has many four-digit message numbers;
    therefore, some command invocations will now result in four-digit
    return codes. Applications that depend on 10-character message
    header lengths and/or three-digit control program command return
    codes should be examined. Systems using programmed operator
    facilities must examine their routing tables for any changes
    necessary.
       Compatibility Statement for VM/SP HPO:
       While one of the primary objectives of VM/XA System Product
Release 1 is to provide a growth path for VM/SP HPO customers with
maximum compatibility to ease migrations, due to factors such as
architectural differences, full compatibility is not possible.  VM/XA
System Product Release 1 has made every effort to fulfill the
migration objective by keeping, where possible, command syntax,
responses and message text the same.
       The bimodal CMS component of VM/XA  System Product Release 1
is generally compatible with the CMS component of VM/SP Release 5.
       Details of incompatibilities and conversion considerations may
be found in the VM/XA System Product Application Conversion Guide
(SC23-0403) and the VM/XA System Product Conversion Notebook
(SC23-0357).
PERFORMANCE CONSIDERATIONS: The performance of VM/XA  System Product
Release 1 can be viewed from three major environmental perspectives:
1.  High capacity CMS environments, which include interactive as well
    as CMS-based production applications
           VM/XA SP Release 1 offers new opportunities to those VM/SP
    HPO installations experiencing growth constraints due to
    System/370 limitations.  VM/XA SP can support significantly more
    users then VM/SP HPO through access to the larger single-image
    capabilities of IBM 308X Model 3084 or IBM 3090 processors Models
    200E, 300E, 400, 400E, and 600E, larger real memory, addressing
    capabilities above the 16-megabyte line and the XA I/O subsystem.

           VM/XA SP Release 1 performance will approach that of VM/SP
    HPO Release 5 operating in an unconstrained System/370
    environment.
           Relative to VM/XA SF, additional CMS interactive users can
    be supported as a result of enhancements to control program logic
    including scheduler enhancements.
2.  Guest performance where VM/XA SP Release 1 is used primarily to
    support guest production or test and maintenance of guest
    operating systems such as MVS/XA
           Guest performance will be at least equivalent to that
    experienced under VM/XA SF Release 2.
3.  Numerically Intensive Computing environments
           Numerically Intensive Computing performance will be
    equivalent to that experienced under VM/XA SF Release 2 or VM/SP
    HPO Release 5.
       Specific performance information will be provided by general
availability.
PLANNING INFORMATION
STORAGE ESTIMATES: The resident nucleus for VM/XA System Product
Release 1 will be approximately one megabyte and the minimum
supported storage size will be four megabytes.
PACKAGING: VM/XA System Product will be shipped with the combined
components of:
o   VM/XA System Product Control Program
o   VM/XA System Product CMS (VM/SP Release 5 CMS with 370-XA
    extensions)
SYSTEM INTEGRITY
       System integrity is an important characteristic of VM/XA
System Product.  This announcement extends IBM's previous statements
on system integrity to the VM/XA System Product environment.  For
VM/XA System Product Release 1, IBM will now accept APARs that
describe exposures to system integrity or that describe problems
encountered when a program running in a virtual machine not
authorized by a mechanism under the customer's control introduces an
exposure to system integrity.
       IBM has implemented specific design and coding guidelines for
maintaining system integrity in the development of VM/XA System
Product. Procedures have also been established to make the
application of these design and coding guidelines a formal part of
the design/development process.
       However, since it is not possible to certify that any system
has perfect integrity, IBM will accept APARs that describe exposures
to the system integrity of VM/XA System Product or that describe
problems encountered when a program running in a virtual machine not
authorized by a mechanism under the customer's control introduces an
exposure to the system integrity of VM/XA System Product, as defined
below.
       IBM will continue its efforts to enhance the integrity of
VM/XA System Product and to respond promptly when exposures are
identified in VM/XA System Product and any subsequent releases.
VM/XA SYSTEM PRODUCT SYSTEM INTEGRITY DEFINITION: VM/XA  System
Product control program system integrity is defined as the inability
of any program running in a virtual machine not authorized by a VM/XA
System Product control program mechanism under the customer's control
and/or a guest operating system mechanism under the customer's
control to:
o   Circumvent or disable the control program main or secondary
    storage protection.
o   Access a resource protected by the Resource Access Control
    Facility (RACF). Resources protected by RACF include virtual
    machines, mini-disks, and terminals.
o   Access a control program password-protected resource.
o   Obtain control in real supervisor state or with privilege class
    authority or directory capabilities greater than those it was
    assigned.
o   Circumvent the system integrity of any guest system which itself
    has system integrity as the result of an operation by any VM/XA
    System Product control program facility.  Specifically, this
    includes MVS/370, MVS/XA, VM/SP, and VM/SP HPO Release 3 and
    subsequent releases, VM/XA Systems Facility Release 2 and VM/XA
    System Product and subsequent releases.
       Main storage protection refers to the isolation of one virtual
machine from another. The control program accomplishes this by the
use of hardware dynamic address translation, SIE guest storage extent
limitation, and the Set Address Limit facility.
       Secondary storage protection refers to the disk extent
isolation implemented for minidisks/virtual disks through channel
program translation.
       Password-protected resource refers to resources protected by
control program logon passwords and minidisk passwords.
       Guest operating system refers to a control program that
operates under the VM/XA System Product control program.
       Directory capabilities refer to those directory options which
control the use of functions intended to be restricted by specific
assignment, such as those which permit system integrity controls to
be bypassed or those not intended to be generally granted to users.
CUSTOMER RESPONSIBILITIES: While protection of the customer's data
remains the customer's responsibility, data security continues to be
an area of vital importance to IBM. IBM's commitment to the system
integrity of the VM/XA  System Product environment, as described in
this announcement, represents a further significant step to help
customers protect their data.
       Product documentation, subject to change, will describe what
action must be taken and which facilities must be restricted to
complement the system integrity support provided by VM/XA System
Product. Such actions and restrictions may vary depending on the
system, configuration, or environment. The customer is responsible
for the selection, application, adequacy, and implementation of these
actions and restrictions, and for appropriate application controls.
SECURITY, AUDITABILITY, AND CONTROL
       VM/XA System Product includes several facilities to ensure the
security and integrity of the system. Each guest and CMS user runs in
a unique virtual machine definition which, in combination with IBM
370-XA architecture features, prohibits one user from accessing
another's data in storage (unless specifically allowed through shared
segments). Additionally, VM/XA System Product and IBM 370-XA channel
facilities provide protection against channel programs accessing
another user's virtual addresses. Minidisk security is provided by a
password facility to control both read-only and read-write access.
Both logon ID and password checking are provided to minimize
unauthorized system access. User class restructure provides customers
with a more granular ability to control access to commands and
DIAGNOSE codes through customer definition of classes. The VM/SP HPO
Release 5 journaling function is not supported. RACF provides
customers with many of these functions as well as other security
considerations.
       User management is responsible for evaluation, selection and
implementation of these features, for administrative procedures, and
for appropriate controls in application systems and communications
facilities.
RELIABILITY, AVAILABILITY, AND SERVICEABILITY
       VM/XA RAS has been enhanced with the following facilities:
o   IDs are provided in key system control blocks to aid systems
    programmers in analyzing storage dumps.
o   VM/XA System Product Release 1 introduces a redesign of the CCW
    translation function which improves product RAS characteristics
    through an improved functional organization and structure.  This
    will result in easier diagnosis and quicker, more reliable fixes
    when a problem is encountered.
o   A protected end-user facility function as provided by VM/SP and
    VM/SP HPO has been introduced to VM/XA System Product Release 1
    which improves the availability of customer application
    environments by reducing the exposure to errors involving forced
    user interaction with the control program component of VM. This
    may be of particular interest to installations with users
    inexperienced with control program interactions (i.e., users who
    typically only interact with a CMS application).
o   Terminal enhancements are provided which can improve the
    availability of a system. Installations can add or move displays

    without necessarily having to reassemble the control data set
    (HCPRIO) or re-IPLing.
