Prerequisites for installing and running WAS Network Deployment

Before you install WAS Network Deployment, 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

For information about the prerequisites for the workstation components of WAS Network Deployment, see Workstation prerequisites for installing WAS.

iSeries and AS/400 hardware requirements

Use the IBM Workload Estimator for iSeries 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.

• WAS Network Deployment
  • Recommended minimum server models:
    • iSeries Model 270 with processor feature 2250
    • iSeries Model 820 with processor feature 2395

  • 750 MB of memory (recommended minimum)

    Notes:

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

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

• WAS

  • 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)

      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.

  • 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.

• Disk requirements:

  WAS for iSeries
  Installation option	Description	After installation
  *BASE	WAS	15 MB
  Option 5	Network Deployment	350 MB
  WebSphere MQ classes for Java and JMS V5.3 for iSeries
  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

  Note: If you are also installing WAS, see iSeries prerequisites for installing WAS for additional disk requirements.

• 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 Network Deployment.
• OS/400 Host Servers (5722-SS1 option 12)
  Required for remote installation.
• All necessary fixes. For a current list of fixes, see http://www.ibm.com/servers/eserver/iseries/software/websphere/wsappserver/services/service.htm and click PTFs.

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.
