Hardware requirements
Read the information
on the
System Requirements for WebSphere Application Server
V7.0 on z/OS Web page for the complete up-to-date listings
of what hardware is required and supported.
Note: If there is a conflict
between the information provided in the information center and the
information on the supported hardware and software Web pages, the
information on the Web site takes precedence. Prerequisites information
in the information center is provided as a convenience only.
There
are significant performance advantages for those applications doing
floating point arithmetic if the machine has binary floating point
hardware, such as S/390® Parallel Enterprise Server-Generation
5 and later systems.
See Basic Sizing for WebSphere Application Server on
z/OS for a set of basic guidelines for determining how much
real storage and DASD storage you might need.
WebSphere Application Server for z/OS is
a heavy user of auxiliary storage. You might want to add additional
paging volumes before configuring application serving environments.
In
addition, you might want to increase your JES spool space if you use WebSphere Application Server for z/OS tracing
options to the STDOUT DD dataset.
WebSphere Application
Server for z/OS Version 7.0 offers full support for IBM®
System z® Application Assist Processors (zAAPs). zAAPs are designed
to operate asynchronously with the general purpose processors when
executing Java™ programming under control of the IBM JVM.
The IBM JVM processing cycles can be executed on
the configured zAAPs with no anticipated modifications to the Java applications. The zAAPs may be purchased
and installed on z9 – 109, z990, and z890 servers (and follow-on
models only). For more details, see the IBM zAAP Redbooks® at http://www.redbooks.ibm.com/abstracts/sg246386.html?Open .

You
need to enable, and configure the following z/OS elements,
features, and components on each z/OS target
system. Consult the WebSphere Application Server
for z/OS Program Directory and PSP bucket for any
additional required corrective service not listed here. In some cases,
this corrective service must be installed on each target system for WebSphere Application Server to start.
- z/OS (or z/OS.e)
configured as a sysplex (in the case of a single z/OS system,
as a monoplex)
For details, see z/OS MVS Setting
Up a Sysplex.
- z/OS UNIX® System Services (z/OS UNIX)
with an HFS or ZFS file system
For details, see z/OS UNIX System
Services Planning.
- eNetwork Communications Server (TCP/IP) or equivalent
In this
documentation, we refer to eNetwork Communications Server; but you
can substitute an equivalent product.
For details, see z/OS Communications
Server: IP Migration.
- Resource recovery services (RRS)
For details, see z/OS MVS Programming:
Resource Recovery.
- System logger
For details, see z/OS MVS Setting
up a Sysplex.
- A security product such as z/OS Security
Server (RACF®)
In this manual, we refer to Security
Server in examples; but you can substitute an equivalent security
product.
For details, see z/OS Security
Server RACF Migration.
Additional software might be required to support
particular product functions.
