DB2 Warehouse 9.5 system requirements for application servers

Preventive Service Planning


This document lists the hardware, software, disk space, and memory that are required to install the application server components for DB2 Warehouse 9.5.


Requirements for the application server

Ensure that your computer meets the following requirements before you install the application server components of DB2® Warehouse.

Note: DB2 Warehouse does not support the installation of both clients and servers on the same computer in a production environment. For production environments, the operating systems that are supported by the data server and application server are not the same operating systems that are supported by the clients.

Hardware and software

Windows Server 2003 Standard, Enterprise, and Datacenter Editions Service Pack 1, and R2 64 AMD64 or Intel EM64T
  1. HP-UX users: This product uses HP Runtime Environment for J2SE HP-UX 11i platform, adapted by IBM for IBM Software, Version 1.4.2.
  2. Solaris 9 users: WebSphere Application Server 6.1 is only available in a 32-bit version. On the 64-bit version of Solaris, the DB2 Warehouse configuration tool sets up the 32-bit WebSphere server. For details of this setup, see the WebSphere documentation.
  3. Web browsers supported by DB2 Warehouse Administration Console: The DB2 Warehouse Administration Console was certified with Internet Explorer 6.0 with SP 1 and Internet Explorer V7.0 (Windows), and Firefox V1.5 and V2.0.
  4. Web browsers supported by WebSphere Application Server: The administrative console for WebSphere Applications Server supports Internet Explorer 6.0 with SP 1 (Windows), Mozilla 1.7.8, and Firefox V1.5.

Disk space

For each copy of DB2 Warehouse you install on a computer, make sure that you have enough disk space to run the installation program and then run DB2 Warehouse. Additionally, Passport Advantage® customers need extra disk space to store the downloadable installation images.

Temporary space for installable download images (Passport Advantage only)

Before installing DB2 Warehouse, Passport Advantage customers must download the installation images to the target computer. These images contain the installation executable files for the DB2 Warehouse components you are installing. This space is different from the space needed to run the installation program.

Approximately 2.7 GB of disk space is recommended for the installation images of the application server components.

On AIX and HP-UX, you must have enough disk space for the installable images for the entire DB2 Warehouse product, even if you are not installing all the components. This is approximately 7.5 GB.

Temporary space for running the installation program

Approximately 550 MB of disk space is recommended.

Permanent space for the installed components

Approximately 2 GB of disk space is recommended for WebSphere, the DB2 Warehouse Administration Console, and the IBM Alphablox administration tool. If you are installing WebSphere into a 64-bit instance, you will need an additional 500 MB.


Memory for installing the product

A minimum of 1 GB of memory is recommended to install the application server.

Memory for running the product

A minimum of 1 GB of memory is the minimum amount of memory required to run the application server alone. If you run the data warehouse server components on the same computer, 2 GB of memory is recommended.

If you add more DB2 Warehouse components to the same computer, you must have more memory to run them in addition to the memory reserved for the application server.
