Prepare IBM i systems for installation

Select the product components that we 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.

Use this procedure to verify that we are ready to install. Complete the following procedure before beginning to install the product on the IBM i system.


Tasks

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

    1. Enter the Display Software Resources (DSPSFWRSC) command on a CL command line.
    2. Look for an entry with the product Resource ID 5733W90.

      • If we do not find the product Resources ID, then this product has not been installed on the IBM i server.

      • If a previous version of WAS is installed on the server, review the product documentation for running coexisting application servers before we install the new version.

    3. Read the migration documentation if we plan to migrate from the previous version to this version.

  2. Print the Checklist: Installing WAS 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 the 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 install an IBM i cumulative PTF package.

    Task Estimated time
    Prepare for the installation
    Reading release notes and migration instructions, and verifying hardware and software prerequisites 1-2 hours1
    Obtain the product and current fixes Up to 2 weeks
    Install any additional products and IBM i cumulative PTF package 1-2 hours
    Install WAS
    Install WAS on the IBM i server2 45-120 minutes
    Install WAS FixPack (depends on the system) Up to 2 hours
    Create an initial configuration 30 minutes
    Starting WAS 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 WAS documentation page for IBM i .

  5. Verify that the 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 we are running an IBM i server that does not meet the minimum recommended hardware requirements for WAS, we can still install and run the product. However, the WAS environment might run slowly, and the 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.
  7. Obtain and install the correct IBM i cumulative PTF package.

    See Cumulative PTFs for IBM i for more information.

  8. Obtain the WAS product and current fixes.

    Before we install WAS for IBM i, we need to obtain the application server product and current fixes.

    • WAS v9.0 for IBM i

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

    • Cumulative PTFs

      WebSphere Application Server v9.0 for IBM i was tested on a specific IBM i cumulative PTF package level.

      To view the cumulative PTF package tested, see WAS.

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

      We can install and run WAS v9.0 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 the server.

    • Fix Packs

      The IBM i group PTFs are no longer provided in WAS v9.0. Instead, update the product by installing fix packs. See Install and uninstall fix packs.


What to do next

See Install the product offerings to continue the installation.
