Prerequisites for installing and running WebSphere Application Server - Express for iSeries

Before you install WebSphere Application Server - Express, 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
• Workstation requirements

iSeries and AS/400 hardware requirements

Use the IBM eServer Workload Estimator (http://www-912.ibm.com/wle/EstimatorServlet) for help with estimating all system configurations. To estimate the workload for WebSphere Application Server - Express, chose WebSphere Workload on the main menu.

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.

• Your server should meet these requirements:
  • 300 CPW/120 CIW (recommended)
  • 512 MB memory
  • 2 MB L2 cache (recommended)
  • Communications adapter that supports TCP/IP

iSeries and AS/400 required software

• i5/OS Version 5 Release 2 (V5R2), Version 5 Release 3 (V5R3), or Version 5 Release 4 (V5R4)
  Your user profile must have *ALLOBJ authority, with *SECADM special authorities. *IOSYSCFG is required to use the HTTP Server Administration interface.
