NOTE: You must be logged in as root to start the Utility Meter GUI.
The following procedure assumes:
You are running the Utility Meter GUI on the Utility Meter system.
A graphical display, running X11, is attached to the Utility Meter system.
To start the Utility Meter GUI, perform the following procedure:
1. Start a terminal session on the Utility Meter system.
2. Log in as root in the terminal window.
3. Ensure the DISPLAY environment variable is set so that an X11 application is locally displayed.
As a test, the following command should bring up the xclock application:
# /usr/bin/X11/xclock &
If the X11 application is not displayed properly, you must set the DISPLAY environment variable
to the hostname or the IP address of the system you started the terminal window from. For example,
if you started the terminal window on node 10.1.2.3, set the environment variable with the
following command when in the Bourne shell:
# export DISPLAY=10.1.2.3:0.0
After you have set the DISPLAY environment variable, try to display the xclock application again.
If this fails, consult a networking specialist at the customer site.
4. Execute the following command:
# /opt/meter/bin/umGUI
Using a web browser:
Open a web browser and type in the following URL:
/opt/hpws/apache/htdocs/UtilityMeterApplet.jnlp
Microsoft Internet Explorer has been tested to work fine.
By either using the X-Windows capable procedure or the web browser procedure, the window in Figure 3-1
appears showing the Utility Meter GUI.
