[IBM i]

IBM i prerequisites

Before you install WebSphere® Application Server, verify that your hardware and software meet the minimum requirements.

Hardware requirements

Overall system requirements vary based on actual workload requirements. Use IBM® Systems Workload Estimator for sizing assistance.

Systems that do not meet the recommended minimums might 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
  • Recommended minimum server models:
    • WebSphere requires a partition with a minimum of 600 CPW
    • WebSphere applications can benefit from the addition of an Accelerator Feature on models where this is available
    • Each active WebSphere profile requires a minimum of 1 GB of memory
  • Any partition running WebSphere Application Server should have a minimum of 2 GB of memory. This memory requirement is in addition to memory required for any other applications running on your IBM i 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.

IBM i software requirements

The software that is required is as follows:

IBM i Version X Release Y (VXRY)
WebSphere Application Server is supported on IBM i Version 7 Release 1 (V7R1), Version 7 Release 2 (V7R2), and Version 7 Release 3 (V7R3). The IBM i server must be in an unrestricted state, and your user profile must have *ALLOBJ and *SECADM special authorities.

V7R1
  • IBM Java SE 8 64 bit (5761-JV1 option 17)
V7R2
  • IBM Java SE 8 64 bit (5770-JV1 option 17)
V7R3
  • IBM Java SE 8 64 bit (5770-JV1 option 17)

IBM i 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) (5770-DG1)
  • Lotus® Domino® 8 for System i® 8.0 (5733-LD8)
  • IBM Domino 8.5 for i (5733-L85)
