Installing WebSphere Application Server 3.5

To install WebSphere Application Server using the GUI installer, do the following:

  1. Log onto your machine with superuser (root) privileges. Note that when installing WebSphere Application Server, the user ID of this individual cannot contain angle brackets.
  2. If Apache HTTP Server or another Web server on your system is running, stop the Web server. Also, if a version of WebSphere Application Server Version is already installed on your system and running, stop all Application Server processes.
  3. 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 disable the WebSphere Prerequisite Checker before installing WebSphere Application Server. To do this, perform the following steps:
    1. Copy the prereq.properties file from the /cdrom/aix directory to the /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.
  4. If you have not disabled the Prerequisite Checker as detailed in Step 3, run the installation script file by entering the following command:
    # /cdrom/aix/install.sh

    If you have disabled the Prerequisite Checker as detailed in Step 3, run the installation script file by entering the following command:

    # /cdrom/aix/install.sh /prereqfile  /tmp/prereq.properties
  5. Click Next to pass the introductory page.
  6. In the Install Options dialog, select Custom Installation; then click Next.
  7. 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. Ensure that Configure Default Server and Application is selected. If you plan on running WebSphere Application Server with a supported Web server, then also select Web Server Plugins.
  8. Click Next. If necessary, shut down all Web servers you plan to run with WebSphere Application Server and proceed.
  9. If you opted to install a plug-in, the Choose Webserver Plugins page displays.
    Upgrade dialog

    Select Apache 1.3.12 plug-in. You must separately purchase and install Apache HTTP Server. Only IBM HTTP Server 1.3.12 is provided with WebSphere Application Server.

  10. On the Database Options dialog, do the following:
    1. For Database Type, select DB2.
    2. For Database Name, give the name of the database to use. The default is was.
    3. For DB Home, specify the path for the database program. It is /home/db2inst1.
    4. For DB URL, specify the URL for accessing the database. You will likely want to take the default, which has the form jdbc:db2:was.
    5. For Database User ID, specify your user name. If you have already installed DB2 UDB, ensure that you specify the DB2 instance owner (db2inst1).
    6. For Database Password and Confirm Password, enter your password. If you have already installed DB2 UDB, ensure that you specify the password for the DB2 instance owner (db2inst1). Note that DB2 UDB requires a password of 8 or fewer characters.
    7. Click Next.
  11. On the Security Options dialog, fill in the user ID, security password, and confirming password to use for the application server. If you do not need special key ring files, click Next to take the default key ring files and to move to the Product Directory dialog.

    If you need special key ring files, move to the key ring section, designate client and server files and passwords, and then click Next until you are at the Product Directory dialog.

  12. Specify the destination directories and click Next.
  13. Click Next again and then OK to begin the installation.
  14. The next page points you to the README. If you select to view the README and a Netscape browser does not open on the README, look in the <main_Application_Server_directory>/web/InfoCenter/was directory for the readme.html file. 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.
