Before you install WebSphere® Application
Server for iSeries®, verify
that your hardware and software meet the minimum requirements.
iSeries hardware
requirements
Use the IBM® Systems
Workload Estimator for help with estimating all system configurations.
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 if your applications consist solely
of servlets and JSP files
- Recommended minimum server models:
- iSeries Model 270 with
processor feature 2250
- iSeries Model 820 with
processor feature 2395
- 750 MB of memory for your WebSphere Application
Server environment (recommended minimum). 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.
- Minimum server requirements if your applications contain enterprise
beans
- Recommended minimum server models:
- AS/400e server 170 with
processor feature 2385
- AS/400e server 720 with
processor feature 2062
- iSeries Model 270 with
processor feature 2250
- iSeries Model 820 with
processor feature 2395
- 750 MB of memory for your WebSphere Application
Server environment (recommended minimum). 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.

and click PTFs.
iSeries 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) 5722-DG1, 5761-DG1, or 5770-DG1)
- Lotus® Domino® for iSeries 6.0
(5733-LD6)
- Lotus Domino for iSeries 6.5
(5733-L65)
- DB2® Query
Manager and SQL Development Kit for iSeries (5722-ST1
5761-ST1 or 5770-ST1)
- The DB2 Query Manager and
SQL Development Kit for iSeries help
you develop client applications.
- IBM Developer Kit for Java, Version 1.5
- WebSphere Application
Server can be enabled to use IBM Developer
Kit for Java, Version 1.5, option
8 or option 9. See the topic enablejvm command for more information
on how to enable WebSphere Application
Server to use IBM Developer
Kit for Java, Version 1.5.
- For V5R4, you can optionally enable WebSphere Application Server to use 5722-JV1
option 8.
- For V6R1, you can optionally enable WebSphere Application Server to use 5761-JV1
option 8 or option 9.
- For V7R1, you can optionally enable WebSphere Application Server
