Prepare the operating system for installation

Select the product components that you intend to install and verify that the product prerequisites are met. Also, plan for the amount of time required to perform each step of the installation.

Overview

Use this procedure to help verify that you are ready to install. Complete the following procedure before you begin to install WebSphere Application Server on your iSeries system.

Procedure

1. Determine if WebSphere Application Server is already installed on your server.

   1. Enter the Display Software Resources (DSPSFWRSC) command on a CL command line.

   2. Look for an entry with the product Resource ID 5733W61.

      • If you do not find the product Resources ID, then this product has not been installed on your iSeries server.

      • If a previous version of WebSphere Application Server is installed on your server, read the coexistence instructions before you install the new version.

   3. Read Overview of migration, coexistence, and interoperability if you plan to migrate from the previous version to this version.

2. Print the Checklist: Installing WebSphere Application Server on the i5/OS platform to use as a checklist during the installation process.

3. Determine the time requirements for installation.

   Plan to set aside enough time for each step of the process. Depending on your server specifications, the process may take more or less time than the estimates provided in this documentation.

   The installation process might require at least one initial program load (IPL or restart) of the server, if you need to install a cumulative PTF package.

   See Time requirements for installing for more information.

4. Read the product Release Notes for important information about the product.

   See the WebSphere Application Server documentation page for iSeries (http://www.ibm.com/eserver/iseries/software/websphere/wsappserver/docs/docws61.html) for links to the Release Notes.

5. Verify that your system meets all hardware and software prerequisites, and install prerequisite software if necessary.

   Verify that the iSeries prerequisites are satisfied. Install prerequisite software if necessary.

   If you are running an iSeries server that does not meet the minimum recommended hardware requirements for WebSphere Application Server, you can still install and run the product. However, the WebSphere Application Server environment might run slowly, and your applications might not run successfully.

   See iSeries prerequisites for more information.

6. Verify that your workstation meets all hardware and software prerequisites, and install prerequisite software if necessary.

   See Workstation prerequisites for more information.

7. Obtain and install the correct i5/OS cumulative PTF package.

   See Cumulative PTFs for iSeries for more information.

8. Obtain the WebSphere Application Server product and current fixes.

   Before you install WebSphere Application Server V6.1 for i5/OS, you need to obtain the WebSphere Application Server V6.1 product and current fixes. It can take up to two weeks to receive the product.
