[IBM i]

Preparing the operating system for installation on IBM i

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

Use this procedure to verify that you are ready to install. Complete the following procedure before you begin to install the product on your IBM® i 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 5733W80.
      • 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 the migration documentation if you plan to migrate from the previous version to this version.
  2. Print the Checklist: Installing WebSphere Application Server on the IBM i 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.

    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. Tasks for preparing your operating system.

    The following table shows the tasks for preparing your operating system.

    Task Estimated time
    Preparing for the installation
    Reading release notes and migration instructions, and verifying hardware and software prerequisites 1-2 hours1
    Obtaining the product and current fixes Up to 2 weeks
    Installing any additional products and IBM i cumulative PTF package 1-2 hours
    Installing WebSphere Application Server
    Installing WebSphere Application Server on your IBM i server2 45-120 minutes
    Installing WebSphere Application Server Group PTF (depends on your system) Up to 2 hours
    Creating an initial configuration 30 minutes
    Starting WebSphere Application Server for the first time 1-20 minutes
    Verifying the installation 10 minutes

    1 This estimate applies if all product prerequisites are met. It does not take into account the time required to install additional prerequisite software.

    2 Actual time requirement depends on the method used.

  4. Read the product release notes for important information about the product.

    See the WebSphere Application Server documentation page for IBM i .

  5. 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.

  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 IBM i cumulative PTF package.

    See Cumulative PTFs for IBM i for more information.

  8. 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.

    • WebSphere Application Server Version 8.5 for IBM i

      For information about how to order the product, see the Ordering information section of the WebSphere Application Server packaging information page.

    • Cumulative PTFs

      WebSphere Application Server Version 8.5 for IBM i was tested on a specific IBM i cumulative PTF package level.

      To view the cumulative PTF package tested, see WebSphere Application Server PTFs.

      From the PTFs page, select the link for your operating system release level. On the resulting page, click the Cumulative Package link.

      You can install and run WebSphere Application Server Version 8.5 for IBM i successfully on earlier or later cumulative PTF packages.

      See Determining the proper cumulative PTF level on IBM i for more information about determining the cumulative PTF package level for your server.

    • PTFs

      To install the WebSphere Application Server product, ensure that you have a recent level of the Java group PTF installed. For V5R4M0, level 13 or higher is recommended.

      The WebSphere Application Server Version 8.5 for IBM i group PTF includes fixes for WebSphere Application Server and other IBM i products such as IBM DB2 Universal Database™, IBM Developer Kit for Java, and the IBM HTTP Server.

      Installing the group PTF requires an IPL of your server, so plan accordingly.

      To determine which IBM i group PTF you must order and install, see the WebSphere Application Server for IBM i PTFs web page. Group PTF numbers differ by WebSphere Application Server product and IBM i release level.

What to do next

See Task overview: Installing on IBM i to continue the installation.
