EPICenter Client Initialization

problems arise.
Clear your browser’s cache, exit the browser, and restart it. This frequently clears up
miscellaneous start-up problems in the client.
In Internet Explorer, clearcache by selecting InternetOptions undertheTools Menu, then
clicking Delete Files under the Temporary Internet Files sectionof the General tab.
In Netscape,clear cache by selecting Preferences under the Edit menu, then click on
Advanced, and select Cache. Clickeachof theseparate buttonsforclearingmemorycache
and disk cache.
Problem: After running for a while, the display disappears in some applets.
Under some conditions the Java Plug-in can run out of memory. If you are running with
theJavaConsoleenabled,youmaysee“OutofMemory”errorsrecordedintheconsolelog
file. To alleviate this problem, you can grant the plug-in more memory through the Java
Plug-in Control Panel.
1 From the Windows Startmenu, run the Java Plug-in Control Panel.
Under Solaris, run
ControlPanel,whichresidesinthenetscape/j2pi directory.
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 theplug-in to use up to 128 MBytes of virtual
memory, and should prevent out-of-memory problem.
For Solaris, due to a bug in the Control Panel, you must enter the command
without the initial
X,andwith a space between the small x and the memory
specification, as follows:
-mx nnnm
Note that Sun could fix this problem at any time. Check with Sun Microsystems
or look at the Extreme Networks web site to determine whether the problem has
been fixed.
