iSeries prerequisites for installing and running WAS

Before you install WAS, verify that your hardware and software meet the minimum requirements.

• iSeries and AS/400 hardware requirements
• iSeries and AS/400 required software
• iSeries and AS/400 optional software

iSeries and AS/400 hardware requirements

Use the IBM Workload Estimator for iSeries (http://www-912.ibm.com/wle/EstimatorServlet) 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.

• If your applications consist only of servlets and JavaServer(TM) Pages (JSP) files, your server should meet these requirements:
  • Recommended minimum server models:
    • iSeries Model 270 with processor feature 2250
    • iSeries Model 820 with processor feature 2395

  • 750 MB of memory (recommended minimum)

    Note:

    1. These requirements are based on a single WAS instance. Additional instances running concurrently will require additional resources.

    2. These requirements represent the recommended minimum requirements. Deployments which must support many users or require shorter response times may require additional resources.

• If your applications contain enterprise beans, your server should meet these requirements:
  • 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 2252
    • iSeries Model 820 with processor feature 2396

  • 1 GB of memory (recommended minimum)

    Notes:

    1. These requirements are based on a single WAS instance. Additional instances running concurrently will require additional resources.

    2. These requirements represent the recommended minimum requirements. Deployments which must support many users or require shorter response times may require additional resources.

  Installation option	Description	Disk space after installation
  *BASE	WebSphere MQ classes for Java and JMS	15 MB
  Option 1	WebSphere MQ classes for Java and JMS - Samples	1 MB

• Communications adapter that supports TCP/IP

iSeries and AS/400 required software

• OS/400 Version 5 Release 1 (V5R1) or Version 5 Release 2 (V5R2)
  The iSeries server must be in an unrestricted state, and your user profile should be user type (user class) *SECOFR and have a value of *USRCLS for special authority.

• IBM Developer Kit for Java^(TM) (5722-JV1), Version 1.3 (option 5).

• OS/400 Qshell(5722-SS1 option 30)
  Required for local installation and to use scripts in WAS.

• OS/400 Host Servers (5722-SS1 option 12)
  Required for remote installation.

• All necessary fixes. For a list of current fixes, see http://www.ibm.com/eserver/iseries/software/websphere/wsappserver/ and click PTFs.

• HTTP server
  Not needed for installation, but required to support requests for servlets and JSP resources that you want to be handled by an HTTP server residing natively on iSeries. If you plan to deploy only enterprise beans, it is not needed. WAS supports these HTTP server products:

  • IBM HTTP Server (powered by Apache) (5722-DG1)
  • Lotus Domino for AS/400 R5 (5769-LNT)
  • Lotus Domino for iSeries 6.0 (5733-LD6)
  • Lotus Domino for iSeries 6.5 (5733-L65)

iSeries and AS/400 optional software

• OS/400 Digital Certificate Manager (5722-SS1 option 34)
  Not required for installation, but required if you plan to use Secure Sockets Layer (SSL) protocol.

• A Cryptographic Access Provider
  Not needed for installation, but required if you plan to use SSL. You can choose one of these options: 5722-AC2 (56-bit), 5722-AC3 (128-bit).

• DB2^(R) Query Manager and SQL Development Kit for iSeries (5722-ST1)
  Can be helpful in developing client applications.
