Raritan Serial Client Requirements for Java
The Raritan Serial Client (RSC) requires a minimum 1 GHz PC with 512 MB RAM. Java must
be installed to access targets (managed devices) before you can use the RSC.
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, of course for
1.5.0_02).
Depending on your operating system and browser, it is possible that you need to adjust some 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:
http://www.java.com/en/download/help/testvm.xml
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 browser based RSC does not need to make any changes to the Runtime parameters for
Java Applets. Do the following 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.

To increase the heap settings so that more RSC applets can be launched to access multiple
Dominion SX targets:
1. Launch the Java Control Panel, which is located in the:
• Advanced Tab in JRE 1.4.x
• Java Tab in JRE 1.5
2. Locate Java Runtime Settings.

3. Insert the values of the Java Runtime Parameters using the syntax in the following table,
which contains the non-standard options.
