Starting the application client
NOTE: When you run the applet, if your system does not have the required Java Plug-in, you will be
automatically taken to the web site for downloading the plug-in. You must also set yourbrowser
security parametersto enable Java.
If you have done this and the client still is not loading, seeGUI Troubleshooting.
Starting the application client
Users with administrator privileges on a LifeKeeper server can run the application client from that
server. To start the LifeKeeper GUI app run /opt/LifeKeeper/bin/lkGUIapp from a graphical
window.
If you have done this and the client still is not loading, seeGUI Troubleshooting.
Exiting GUI Clients
Select Exit from the File menuto disconnect from all servers and close the client.
Configuring the LifeKeeper GUI
Configuring the LifeKeeper Server for GUI Administration
Perform the following steps for each LifeKeeper server. Each step contains references or links for
more detailed instructions.
1. You must install the Java Runtime Environment (JRE) or Java Software Development Kit
(JDK) on each server. See the SPS for Linux Release Notes for the required Java version and
URL to access the required download. Note: You may install the JRE from the SPS
Installation Image File by running the setup script from the installation image file and opting
only to install the JRE. (See theSPSfor Linux Installation Guide for more information.)
2. Start the LifeKeeper GUI Server on each server (see Starting/Stopping the GUI Server). Note:
Once the GUI Server has been started following an initial installation, starting and stopping
LifeKeeper will start and stop all LifeKeeper daemon processes including the GUI Server.
3. If you plan to allow users other than root to use the GUI, then you need to Configure GUI
Users.
Running the GUI
You can run the LifeKeeper GUI:
l on the LifeKeeper server in the cluster and/or
l on a remote system outside the cluster
See Running the GUI on the LifeKeeper Server for information on configuring and running the GUI on
a server in your LifeKeeper cluster.
