# /opt/SUNWjeev/bin/iplanet_serv start

    Note -

    End users must start their session over because all the session information is contained in the i-Planet server. No warning message is sent to the end users.

Tuning the Web Server

Overview

This section provides information on tuning the web server for more efficient operation within the operating environment.

As root, you can:

The shell script in this file should run before the shell script in file S42rp, which contains the script that starts the Java Web Server(TM).

Using the Java Web Server Administration Tool

It should be unnecessary to administer the Java web Server through the Java Web Server Administration tool. But should it be necessary, use the following procedure to enable the password and log in to the Java Web Server.

The default setting for logging in to the Java Web Server Administration tool is set to admin as the login. The default password, admin, as the password is disabled when the Java web server is installed.

If you need to run the Java Web Server Administration tool, you must

To Enable the Password and Log In to the Java Web Server Administration Tool

  1. Enable the default password for the Java Web Server Administration tool:


    # cp /opt/SUNWjeev/realms/data/defaultRealm/keyfile/\

opt/SUNWjeev/realms/data/adminRealm/keyfile

  2. Stop and restart the web server on the i-Planet server

    For information on stopping and restarting the web server, see the procedure "To Stop and Restart the Web Server on the i-Planet Server" in this chapter.

    Caution - Caution -

    The default login is admin and the default password is admin. This is a security risk. Please log in to the Java Web Server Administration tool and change the password.

  3. In a browser, type the following URL to run the Java Web Server Administration tool:


    http://i-Planet_server:9090/

    Port 9090 is the administration port for the Java Web Server.
