Preparing Windows systems for installation

This topic describes how to prepare your Windows® systems for the installation of IBM® WebSphere® Application Server products.

Before you begin

The installation uses an InstallShield MultiPlatform (ISMP) wizard. You can use the graphical interface of the wizard. You can also use the wizard in silent mode.

[Windows 2008 Server] [Windows 7] [Fix Pack 7 or later] New feature: This fix pack is the minimum supported fix pack level for the product on the Microsoft Windows Server 2008 R2 and Windows 7 operating systems.newfeat

About this task

Preparing the operating system involves such changes as allocating disk space and installing patches to the operating system. IBM tests WebSphere Application Server products on each operating system platform. Such tests verify whether an operating system change is required for WebSphere Application Server products to run correctly. Without the required changes, WebSphere Application Server products do not run correctly.

Procedure

  1. Log on to a user ID that belongs to the administrator group.

    Log on as a member of the administrator group to successfully install the product. You cannot create Windows services from a user ID that does not belong to the administrator group. The creation of Windows services requires the user to have the advanced user rights Act as part of the operating system and Log on as a service.

    During the procedure, you can assign another ID or the one you are using to install as the user who will log on the Windows service. That user requires the advanced user right: Log on as a service.

    However, if you do not have this advanced user right or if the user ID that is to log on the Windows service does not have the advanced user right, the Installation wizard assigns the advanced right to the user.

    Tip: Windows service creation can be disabled by launching the graphical interface from the command line with the following additional option:
    install.exe -OPT PROF_winserviceCheck="false"
  2. Optional: Download and install a Web browser. You must install a Web browser if you want to use the launchpad application. If your system does not have a default browser or the browser has been corrupted or installed incorrectly, then you might experience errors when trying to open various hyperlinks in the installation wizard panels.
  3. Stop all WebSphere Application Server-related Java™ processes on the machine where you are installing the product.
  4. Stop any Web server process such as the IBM HTTP Server.
  5. Stop all instances of the process_spawner.exe program.
  6. Provide adequate disk space. The amount of disk space required varies with the number of features or products installed. If you are installing the product using the installation wizard, the installation summary panel indicates the approximate amount of disk space required based on the features and products you have selected. Installing all features and products, including the centralized installation manager (CIM) requires approximately 3 GB of disk space. Installing all features and products without the CIM requires approximately 2 GB of disk space. This estimate includes the following products, components, and features:
    • Main application server product installation
    • Profiles
    • Sample applications
    • IBM HTTP Server
    • Web server plug-ins
    • Application Client for WebSphere Application Server
    • IBM Update Installer for WebSphere Software

    If you plan to migrate applications and the configuration from a previous version, verify that the application objects have enough disk space. As a rough guideline, plan for space equal to 110 percent of the size of the applications.

  7. Verify that prerequisites and corequisites are at the required release levels.

    Although the installation wizard checks for prerequisite operating system patches with the prereqChecker application, review the prerequisites on the Supported hardware and software Web site if you have not done so already.

    Refer to the documentation for non-IBM prerequisite and corequisite products to learn how to migrate to their supported versions.

  8. Download Windows Script 5.6 to create Start menu items correctly on Windows 2000 and Windows XP.

    Download Windows Script 5.6 from the following Microsoft® Web page: http://www.microsoft.com/ downloads/ details.aspx? FamilyId= C717D943-7E4B-4622-86EB-95A22B832CAA.

  9. Verify that the Java 2 SDK on your copy of the product disk is functioning correctly.

    If you created your own product disk from an ISO image or by copying the actual disk, perform the following steps to verify that the Java 2 SDK on the product CD-ROM or DVD is working correctly.

    1. Change directories to the JDK\jre.pak\repository\package.java.jre\java\jre\bin directory on the product disk. Type the following command:
      cd disk_drive_D:\JDK\jre.pak\repository\package.java.jre\java\jre\bin
    2. Verify the version of the Java 2 SDK. Type the following command:
      .\java -version

      The command completes successfully with no errors when the Java 2 SDK is intact.

Results

This procedure results in preparing the operating system for installing the product.

What to do next

After verifying prerequisites, verifying the product disk, and setting your installation goals, you can start installing. Use one of the following links to open the installation procedure that you require.
Install the Network Deployment product on your operating system.
  • Perform a custom installation.

    The custom installation lets you select features to install. The features include the core product files (required), the Javadoc (optional), and the Sample applications (optional).

    See Installing the Network Deployment product.

  • Perform a silent installation.

    A silent installation requires you to edit the example response file to contain all of your installation choices. After creating a valid response file, issue the install command with the silent parameter from a command window.

    See Installing silently.

  • Install additional features to an existing product.

    After using a custom installation to omit one or both of the optional features, you can install the product again to add the features. Select a missing feature to install it.

    See Installing additional features on an existing Network Deployment product.
