Hardware requirements
Read the information
on the
WebSphere Application Server detailed system requirements 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 website 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
8.0 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 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.
