EPICenter Client Issues

Problem: Client is unable to connect to the EPICenter server.
Verify that the EPICenter Server process is running.
Verify that the server is running on the specified port. You can try to connect to the server's HTTP port
using a browser. If the server is running and you are using the correct port, the EPICenter main page
will be displayed.
Verify that the EPICenter client and the EPICenter server are the same version. As of EPICenter 5.0, the
client and server must be the same version—if you have upgraded your EPICenter server, you must
also upgrade all your EPICenter installed clients to the same version.
If you are running the client on the same system as the EPICenter server, you can also use the Port
Configuration utility to determine the port on which the EPICenter server is running.
To run the Port Configuration utility, go to the Windows Start menu, and select Programs, then Extreme
Networks, followed by EPICenter 6.0, then Port Configuration.
For more information on the Port Configuration utility, see
Problem: Colors in client interface are incorrect (Windows 2003, Windows XP).
The Color Palette must be set for 65536 colors (or True Color). If your display is set for only 256 colors,
the colors in the left-hand panel (the Navigation Toolbar) and the EPICenter applets themselves may be
incorrect.
To change the color palette, double-click the Display icon in the Control Panel, select the Settings tab,
and use the drop-down list in the Color Palette field to select the appropriate setting.
Problem: After running for a while, the display disappears in some applets (Windows, browser
only).
Under some conditions in the browser client, the Java Plug-in can run out of memory. If you are
running with the Java Console enabled, you may see "Out of Memory" errors recorded in the console
log file. To alleviate this problem, you can grant the plug-in more memory through the Java Plug-in
Control Panel.
1 From the Windows Start menu, run the Java Plug-in Control Panel.
The Plug-in Control Panel should appear with the Basic page displayed.
2 In the Java RunTime Parameters field, enter the following without any embedded spaces:
-Xmxnnnm
is the maximum number of megabytes of virtual memory available to the plug-in.
nnn
For example, entering
should prevent out-of-memory problem.
3 If you see similar problems with the client application, restart the client to fix the problem.
Problem: Browser does not bring up the Login page.
Verify the version of the browser you are using. See the system requirements in the EPICenter Installation
and Upgrade Guide or see the EPICenter Release Note shipped with the software.
EPICenter Concepts and Solutions Guide
allows the plug-in to use up to 128 MBytes of virtual memory, and
-Xmx256m
