iSeries prerequisites

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.

Disk requirements

Installation option Description Disk space after installation
WebSphere Application Server WebSphere Application Server run time 900 MB
Application Server Samples Sample applications 80 MB
Application Client Client development and run time 160 MB
Web Server Plug-ins Web server plug-ins 100 MB

iSeries software requirements

The software required is as follows:

IBM i (also referred to as i5/OS) Version X Release Y (VXRY)
WebSphere Application Server is supported on Version 5 Release 3 (V5R3), Version 5 Release 4 (V5R4), Version 6 Release 1 (V6R1),

WebSphere Application Server Versions 6.1.0.29 and higher are also supported on IBM i Version 7 Release 1 (V7R1).

The iSeries server must be in an unrestricted state, and your user profile must have *ALLOBJ and *SECADM special authorities.

Note:
IBM Developer Kit for Java (5722-JV1), Version 1.5
  • 5722-JV1 option 7 is required to install WebSphere Application Server on V5R3 or V5R4.
  • 5761-JV1 option 7 is required to install WebSphere Application Server on V6R1.
  • 5761-JV1 option 8 is required to install WebSphere Application Server on V7R1.
i5/OS Qshell 5722-SS1, 5761-SS1 or 5770-SS1 option 30)
Required to run installation scripts and to use other scripts in WebSphere Application Server.
i5/OS Extended Base Directory Support (5722-SS1, 5761-SS1 or 5770-SS1 option 3)
Required for installation.
i5/OS Portable Application Solutions Environment (5722-SS1, 5761-SS1 or 5770-SS1 option 33)
Required to use Tivoli® Performance Viewer.
i5/OS Host Servers (5722-SS1, 5761-SS1 or 5770-SS1 option 12)
Required for installation.
i5/OS Digital Certificate Manager (5722-SS1, 5761-SS1 or 5770-SS1 option 34)
Required for installation to use Secure Sockets Layer (SSL) protocol.
All necessary fixes
For a list of current fixes, see http://www.ibm.com/eserver/iseries/software/websphere/wsappserver/ 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 to use 5761-JV1 option 9.
