Running the GUI on a Remote System
l If you already have a user policy file, you can add the required entries specified
in /opt/LifeKeeper/ htdoc/java.policy on a LifeKeeper server into the existing
file using a simple text editor. See Java Security Policy for further information.
2. You must set your browser security parameters to low. This generally includes enabling of
Java and Java applets. Since there are several different browsers and versions, the
instructions for setting browser security parameters are covered in Setting Browser Security
Parameters for the GUI Applet.
Note: It is important to use caution in visiting external sites with low security settings.
3. When you run the GUI for the first time, if you are using Netscape or Internet Explorer and
your system does not have the required Java plug-in, you may be automatically taken to the
appropriate web site for downloading the plug-in. See the SPSfor Linux Release Notes for the
required Java Plug-in version and URL to access the download.
Running the GUI on a Remote System
After you have completed the tasks described above, you are ready to run the LifeKeeper GUI as a
Java applet on a remote system.
1.
Open the URL, http://<server name>:81, for the LifeKeeper GUI webpage (where <server
name> is the name of the LifeKeeper server). The web page contains the LifeKeeper splash
screen and applet. When the web page is opened, the following actions take place:
l the splash screen is displayed
l the applet is loaded
l the Java Virtual Machine is started
l some server files are downloaded
l the applet is initialized
Depending upon your network and system configuration, these actions may take up to 20
seconds. Typically, browsers provide some minimal status as the applet is loading and
initializing.
If everything loads properly, a Start button should appear in the applet area. If the splash
screen does not display a Start button or you suspect that the applet failed to load and
initialize, refer to Applet Troubleshootingor see Network-Related Troubleshooting.
2. When prompted, click Start. The LifeKeeper GUI appears and the Cluster Connect Dalog is
automatically displayed. Once a Server has been entered and connection to the cluster
established, the GUI window displays a visual representation and status of the resources
protected by the connected servers. The GUI menus and toolbar buttons provide LifeKeeper
administration functions.
Note: Some browsers add “Warning: Applet Window” to windows and dialogs created by an
applet. This is normal and can be ignored.
