Installing additional features on an existing base product

This topic describes how to install additional features to an existing IBM WebSphere Application Server, Version 6 installation.

Before you begin

This topic describes one of the available installation procedures.

If this topic does not describe the procedure that you meant to select, click the link to the description of the appropriate installation procedure before you issue the install command.

Knowing what component to install and in what order to install the component is an important consideration. Before starting this installation, see Planning to install WebSphere Application Server. The diagrams show typical topologies for the product. The solutions are also in the Installation solution diagrams in the launchpad. See Using the launchpad to start the installation. You cannot run the launchpad remotely to install a product. Only local use of the launchpad is supported.

About this task

Perform the following installation to add features to an existing WebSphere Application Server installation.

Procedure

  1. Log on to the operating system.
    [AIX] [HP-UX] [Linux] [Solaris] In addition, select a umask that would allow the owner to read/write to the files, and allow others to access them according to the prevailing system policy. For root, a umask of 022 is recommended. For non-root users a umask of 002 or 022 could be used, depending on whether or not the users share the group. To verify the umask setting, issue the following command:
    umask
    To set the umask setting to 022, issue the following command:
    umask 022
    [Windows] When installing on a Windows® system, a Windows service is automatically created to autostart the application server if your installer user account has the following advanced user rights:
    • Act as part of the operating system
    • Log on as a service
    For example, on some Windows systems, click Administrative Tools > Local Security Policy > User Rights Assignments to set the advanced options. See your Windows documentation for more information.

    [Windows] If you plan to run the application server as a Windows service, do not install from a user ID that contains spaces. A user ID with spaces cannot be validated. Such a user ID is not allowed to continue the installation. To work around this problem, install with a user ID that does not contain spaces.

  2. Stop each running application server with the stopServer command.
    Stop all server processes in all profiles on the machine. For example, issue the following command from the profile_root/bin directory to stop the server1 process in the application server profile:
    ./stopServer.sh server1
    If a server is running and security is enabled, use the following command:
    ./stopServer.sh server1 -user user_ID -password password
  3. Uninstall all maintenance packages.

    You are using the product installation image to install additional features. The features have not had any maintenance applied to them. If you remove all maintenance packages, your entire product will be at the same release level. You can then reapply the maintenance packages as described in a later step.

    Start the Update Installer program with the updi_root/update command to search for and uninstall all maintenance packages.

  4. Insert the disc labeled WebSphere Application Server into the disc drive.

    Mount the drive if necessary as described in tins_mount.dita{ IDEP205A: tins_mount.dita not found. }.

  5. Start the installation.
    Start the installation of a product image with the launchpad script.
    • [AIX] [HP-UX] [Linux] [Solaris] launchpad.sh
    • [Windows] launchpad.bat or launchpad.exe

    Or you can start the installation directly with the install command.

    • [AIX] [HP-UX] [Linux] [Solaris] /WAS/install
    • [Windows] \WAS\install
    If a problem occurs with the Java Runtime Environment (JRE), force the installation to use the correct JRE with the following command, where downloaded_directory is the name of the directory in which you downloaded the image:
    • [AIX] [HP-UX] [Linux] [Solaris] ./install -is:javahome disc_mount_point/downloaded_directory/JDK/jre.pak/repository/package.java.jre/java/jre
    • [Windows] install -is:javahome disc_drive:\downloaded_directory\JDK\jre.pak\repository\package.java.jre\java\jre

    If you have a problem starting the launchpad, use the troubleshooting information in Using the launchpad to start the installation to correct the problem.

    When using the launchpad, launch the installation wizard for WebSphere® Application Server.

    After launching the installation wizard from the launchpad or from the command line, the installer wizard initializes and then displays the Welcome panel.

  6. Click Next to continue.

    The license agreement displays.

  7. Read the license agreement and accept its terms.

    Click the radio button beside the message I accept both the IBM and the non-IBM terms to agree to the license agreement and click Next to continue.

    After you accept the licensing terms, the installation wizard checks for a supported operating system and prerequisite patches. If you encounter a problem such as not having the right prerequisite updates on your system, cancel the installation, make the required changes, and restart the installation.

    Although the installation wizard automatically checks for prerequisite operating system patches with the prereqChecker application, review the prerequisites on the WebSphere Application Server detailed system requirements web site if you have not already done so.

    Although the installation process verifies that the minimum required version of the operating system is available, the installation process might not correctly flag a maintenance upgrade of that operating system version as being a supported configuration. If you have upgraded your supported operating system version to a higher maintenance level and you receive the following error message, then you can ignore the message and click Next.
    Avoid trouble Avoid trouble: Although maintenance upgrades of the same major release are supported, subsequent major releases of the operating system might not be supported.gotcha
    Failed : Your operating system failed the
    prerequisites check.
    
    A supported operating system was not detected. Support for your
    operating system might have been added after the release of the
    product.

    The Web site lists all supported operating systems and the operating system fixes and patches that you must install to have a compliant operating system.

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

  8. After confirming that your operating system is supported and that you have installed all necessary patches, click Next to continue.

    The Installation wizard checks for a previous installation at the same product level. This task describes the scenario where a previous installation exists and you are adding features with an incremental installation.

    When the wizard detects a previous installation, it displays the Existing installation panel. The panel lets you add features to the existing installation, or perform a new installation to another directory.

  9. Choose to install additional features. Click Next to continue to the Features selection panel.

    Do not change the installation directory unless another existing installation is in another directory. An incremental installation adds features to the shared binaries identified in the location field.

    You can add uninstalled features at any time, by running the Installation wizard again. Installing additional features does not affect profiles that you might have already created. (Profiles are described in a later step.)

    When adding features during an incremental installation, the wizard displays the Features selection panel next.

  10. Select features to install and click Next.

    In Version 6.1, just one feature is available, which installs the Samples Gallery.

    Table 1. Features for the WebSphere Application Server product
    Feature Description
    Application Server Samples Installs the Samples Gallery applications.

    Performance considerations

    For better performance in either a development or production environment, do not install the Samples. By omitting the Samples, you can improve application server startup time by 60 percent and save 15 percent of disk space. You can save up to 30 percent of process footprint (based on a maximum heap size of 256 MB).

    The Installation wizard displays a confirmation panel.

  11. Review the summary information and click Next to install the product code or Back to change your specifications.
    The disk space shown on the pre-installation summary panel includes space for the Java Virtual Machine (JVM). Subtract the size of the JVM for your operating system to determine the installed size on disc for the features that you selected.
    Table 2. JVM sizes
    AIX® HP-UX Linux® Solaris Windows
    59 MB pa-risc: 109 MB

    64 bit: 137 MB

    ia32: 83 MB

    64 bit: 133 MB

    81 MB ia32: 75 MB

    64 bit: 71 MB

    Verify that you have the total amount of free space shown before installing. Space is required for a working copy of the JVM during the installation.

    The installation wizard creates the uninstaller program and then displays a progress panel that shows which components are being installed. At the end of the installation, the wizard displays the Installation completion panel.

    At the end of the installation, the wizard displays the Installation completion panel.

  12. Verify the success of the installer program by examining the completion panel and the log.txt file for installation status.

    Examine the app_server_root/logs/install/log.txt file to verify that there were no file system or other unusual errors while installing. If there are problems, correct them, and reinstall the product.

    If problems occur, consult the following applicable logs:

    Log files for WebSphere Application Server: The following table shows the installation logs, content, and indicators of success and failure for WebSphere Application Server for Version 6.1:

    If the installation of the core product files fails, fix the error and reinstall.

    If the creation of a profile fails, fix the error and run the Profile Management tool to recreate the profile.

    Troubleshoot the installation if the app_server_root/logs/install/log.txt file or the app_server_root/logs/manageprofiles/profile_name_create.log file does not contain a record of any problems, but problems exist.

    See Troubleshooting installation and Installation component troubleshooting tips for more information.

    [Windows] Examine the Start menu entry. The menu is an indication of a successful installation:
    • [All] Programs > IBM WebSphere > Application Server v6.1

    If problems exist that cause you to reinstall the product, correct the errors, uninstall the product as described in Uninstalling the product, reboot a Windows machine or log off and back on as root on a machine with an operating system such as AIX or Linux, and reinstall.

  13. Click Finish to close the installation wizard.

    See Creating profiles using the graphical user interface for more information.

    Select the check box to open the First Steps console, then click Finish.

Results

The Installation wizard installs the new features in the existing installation root directory. The Installation wizard configures the WebSphere Application Server product for the new features. Further configuration is not necessary at this time.

Further configuration is not necessary at this time. However, you can create additional stand-alone application servers with the Profile Management tool. Each profile is created in the profile_root directory by default.

See Creating profiles using the graphical user interface for more information.
