EPICenter Client
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.
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 5.0 , then Port Configuration .
For more information on the Port Configuration utility, see Appendix B.
Problem: Colors in client interface are incorrect (Windows 2000, 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
nnn
is the maximum number of megabytes of virtual memory available to the plug-in.
For example, entering
-Xmx128m
allows the plug-in to use up to 128 MBytes of virtual memory, and
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 Chapter 1 or see the
EPICenter Release Note shipped with the software.
Problem: Browser client software loads and allows login, but data is missing or other problems arise.
Clear your browser’s cache, exit the browser, and restart it. This frequently clears up miscellaneous
start-up problems in the client.
