Applet Troubleshooting
Applet Troubleshooting
If you suspect that the applet failed to load and initialize, try the following:
1. Verify that applet failed. Usually a message is printed somewhere in the browser window
specifying the state of the applet. In Netscape and Internet Explorer, an icon may appear
instead of the applet in addition to some text status. Clicking this icon may bring up a
description of the failure.
2. Verify that you have installed the Java Plug-in. If your problem appears to be Java Plug-in
related, refer to the Java Plug-in topic.
3. Verify that you have met the browser configuration requirements, especially the security
settings. Refer to Setting Browser Security Parameters for the GUI Applet for more
information. If you don't find anything obviously wrong with your configuration, continue with
the next steps.
4. Open the Java Console.
l For Firefox, Netscape and older versions of Internet Explorer, run the Java
Plug-In applet from your machine's Control Panel and select the option to
show the console, then restart your browser.
l
For recent versions of Internet Explorer, select Tools > Java Console. If you
do not see the Java Console menu item, select Tools > Manage Add-Ons and
enable the console, after which you may need to restart your browser before the
console will appear.
l
For Mozilla, select Tools > Web Development > Java Console.
5.
Reopen the URL, http://<server name>:81 to start the GUI applet. If you've modified the
Java Plug-In Control Panel, restart your browser.
6. Check the console for any messages. The messages should help you resolve the problem. If
the problem appears to be network related, refer to Network-Related Troubleshooting.
Running the GUI on a LifeKeeper Server
The simplest way to run the LifeKeeper GUI is as an application on a LifeKeeper server. By doing so
you are, in effect, running the GUI client and server on the same system.
1. After configuring the LifeKeeper server for GUI Administration, you can run the GUI as an
application on the server by entering the following command as root:
/opt/LifeKeeper/bin/lkGUIapp
2. The lkGUIapp script sets the appropriate environment variables and starts the application. As
the application is loading, an application identity dialog or splash screen for LifeKeeper
appears.
3. After the application is loaded, the LifeKeeper GUI appears and the Cluster Connect dialog is
automatically displayed. Enter the Server Name you wish to connect to, followed by the login
