Preparing IBM i systems 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.
About this task
Procedure
-
Determine if WebSphere® Application Server is already installed on your
server.
- Enter the Display Software Resources (DSPSFWRSC) command on a CL command line.
-
Look for an entry with the product Resource ID 5733W90.
- If you do not find the product Resources ID, then this product has not been installed on your IBM i server.
- If a previous version of WebSphere Application Server is installed on your server, review the product documentation for running coexisting application servers before you install the new version.
- Read the migration documentation if you plan to migrate from the previous version to this version.
- Print the Checklist: Installing WebSphere Application Server on the IBM i platform to use as a checklist during the installation process.
-
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.
Attention: The installation process might require at least one initial program load (IPL or restart) of the server if you need to install an IBM i cumulative PTF package.Table 1.

-
Read the product release notes for important information about the product.
See the Release notes.
-
Verify that your system meets all hardware and software prerequisites, and install prerequisite
software if necessary.
Verify that the IBM i prerequisites are satisfied. Install prerequisite software if necessary.
If you are running an IBM i 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 IBM i prerequisites for more information.
- Verify that your workstation meets all hardware and software prerequisites, and install prerequisite software if necessary.
-
Obtain and install the correct IBM i cumulative PTF
package.
See Cumulative PTFs for IBM i for more information.
-
Obtain the WebSphere Application Server product and current fixes.
Before you install WebSphere Application Server for IBM i, you need to obtain the application server product and current fixes.
