Chapter 8: Port Configuration and Port Access Application

Java Runtime Environment (JRE)
The RSC will function with JRE
™
version 1.4.2_05 or later (except for
JRE version 1.5.0_02). However, for optimum performance, Raritan
recommends using JRE 1.5.0 (except for version 1.5.0_02).
Depending on your operating system and browser, it is possible that you
must adjust JRE configurations to prevent problems with the system's
memory.
Note: Raritan does not support JRE version 1.5.0_02 for use with the
RSC.
JRE provides configuration instructions with the JRE download.
Determine the JRE version on your system by going to the Java
™
Web
page at:

IMPORTANT: When launching RSC from a browser, Raritan highly
recommends that Java Applet Caching be disabled and that you
perform the following steps to make sure that Java does not create
problems for the system's memory.
Java Applets and Memory Considerations
Usually, a browse- based RSC does not need to make any changes to
the Runtime parameters for Java
™
Applets. Following these steps if you
notice any "Out of Memory" errors happening when executing RSC via a
web browser:
 Change the Runtime settings for Java Applets.
 Use the following links to find out how to use Runtime settings in the
Java Control Panel.
