Installing WebSphere Application Server -- Custom Installation option

To install WebSphere Application Server, do the following:

  1. Ensure that you will be installing WebSphere Application Server under a local Windows user ID that is in the Administrative group and has the advanced user rights "Act as part of the operating system" and "Log on as a service."
  2. If IBM HTTP Server or another Web server on your system is running, stop the Web server.

    If you have a level of IBM HTTP Server prior to 1.3.19 on your system, you must uninstall it for the WebSphere Application Server installation program to install IBM HTTP Server 1.3.19.

  3. If you obtained Version 4.0 from the product Web site, run or unpack the downloaded executable.
  4. If you plan to use a Web server or database at a level that exceeds the current version required by WebSphere Application Server, you must do one of the following:

    • Download the most current prereq.properties file from the Web site http://www.ibm.com/software/webservers/appserv/tools.html to a directory such as c:\tmp on the machine onto which you will install WebSphere Application Server.
    • Disable the WebSphere Prerequisite Checker before installing WebSphere Application Server.
      1. Copy the prereq.properties file from the \nt directory to the c:\tmp directory on the machine on which you will install WebSphere Application Server.
      2. Edit this file by finding the line prereq_checker=1 and changing it to prereq_checker=0.

  5. If you have not downloaded a new prereq.properties file or disabled the Prerequisite Checker (Step 3), run setup.exe or, if you have the product CD, run \nt\setup.exe.

    If you have downloaded a new prereq.properties file or disabled the Prerequisite Checker, enter the following command:

    setup.exe -prereqfile c:\tmp\prereq.properties

    You will need 135 MB free in your temp directory (usually on the C drive), even if you are installing on another drive, because the installation shield package unpacks to the temp directory. This will kick off an installation shield package.

  6. Select a language and click OK.
  7. Click Next to pass the introductory page.
  8. If WebSphere Application Server is already installed on your system, a dialog giving you the option to backup and uninstall WebSphere Application Server displays. You now have three options:
    • To backup your files and uninstall WebSphere Application Server, click Backup and Uninstall and then Next to continue with the installation.
    • To install to a different directory, simply click Next and continue with the installation.
    • To migrate your files from a previous release, click Perform Migration. Complete the migration, then run the WebSphere installation program again.

    If WebSphere Application Server is not already installed on your system, proceed to step 9.

  9. In the Installation Options dialog, select Custom Installation; then click Next.
  10. In the Choose Application Server Components dialog, select those components you want and deselect those components you do not want. You will likely want to include the default options.

    Clicking Other JDK displays the Select Java Development Kit dialog. If you have a non-IBM Java development kit installed, we recommend that you specify that you want the Java Development Kit (IBM Developer Kit 1.3.0.). Also specify the destination directory for the IBM Developer Kit. Further, to use the IBM Developer Kit, you must remove your other JDKs from the jre\lib\ext directory. If you use a JDK other than IBM Developer Kit to run WebSphere Application Server, it must be at the XML4j/Xerces 3.1.1 level. Finally, click Next. Otherwise, click Back to exit the dialog.

  11. Click Next. If necessary, shut down all Web servers you plan to run with WebSphere Application Server and proceed.
  12. On the Choose Webserver Plugins page, select IBM HTTP Server V1.3.19. Only IBM HTTP Server 1.3.19 is provided with WebSphere Application Server. You must separately purchase and install the other supported Web servers.
    Choose Webserver Plugins page
  13. On the Security Options dialog, fill in the user ID and password to use for the application server. Do not use the characters < or > for the user ID or password. After you fill in the fields, click Next.
  14. Specify the destination directories and click Next.
  15. On the Database Options dialog, do the following:
    1. For Database Type, select Oracle. If the Application Server will be using a database that is installed on a machine other than the one onto which you are installing WebSphere Application Server, select the Remote Database check box.
    2. For Database Name, give the name of the database to use. The default is orcl.
    3. For Database User ID, specify your user name. Note that if you use an invalid user ID to install WebSphere, it will not successfully register the WebSphere Administrative Server to the NT services database. If you have already installed Oracle 8i, ensure that you specify the Username specified when configuring Oracle 8i for use with WebSphere Application Server (for example, EJSADMIN).
    4. For Password and Confirm Password, enter your password. If you have already installed Oracle 8i, ensure that you specify the Password specified when installing Oracle 8i.
    5. For Path, specify the path for the database program.
    6. For URL, specify the URL for accessing the database. You will likely want to take the default.
    7. For Server, specify the server containing the database program. You will likely want to take the default.
    8. For Port, specify the port for the database. You will likely want to take the default.
    9. Click Next.
  16. Click Next on the next two dialogs and begin the installation.
  17. The next page points you to the README. For the most recent version of the README or release notes, go to Library section of the product Web site at http://www.ibm.com/software/webservers/appserv/.

    Click Finish and, to complete the installation, restart your computer.
