Before you install WebSphere® Application Server,
verify that your hardware and software meet the minimum requirements.
iSeries hardware
requirements
Overall system requirements will vary based
on actual workload requirements. It is highly recommended to use IBM® Systems Workload Estimator for sizing
assistance.
Systems that do not meet the recommended minimums
may be used in environments that support a limited number of users
and where longer server initialization times are acceptable. The recommended
hardware minimum requirements follow:
- Minimum server requirements
- Recommended minimum server models:
- WebSphere requires a partition with a minimum
of 600 CPW
- WebSphere applications can benefit from
the addition of an Accelerator Feature on models where this is available
- Each active WebSphere profile requires a minimum of
1 GB of memory
- Any partition running WebSphere Application Server
should have a minimum of 2 GB of memory. This memory requirement is
in addition to memory required for any other applications running
on your iSeries server.
These requirements are based on a single WebSphere Application
Server profile. Additional profiles running concurrently require additional
resources.
These requirements represent the recommended minimum
requirements. Deployments that must support many users or require
shorter response times might require additional resources.
- Disk requirements

IBM i optional software
The
optional software is as follows:
- HTTP server
- An HTTP server is not required for installation, but recommended
for production environments that use servlets and JSP files. If you
plan to deploy only enterprise beans, you do not need an HTTP server
instance. WebSphere Application Server supports these
HTTP server products:
-
IBM HTTP Server (powered by Apache)
