What is EXPRESSCLUSTER X SingleServerSafe?EXPRESSCLUSTER X SingleServerSafe software configurationEXPRESSCLUSTER X SingleServerSafe consists of following three software applications: EXPRESSCLUSTER ServerThis is a main module of EXPRESSCLUSTER X SingleServerSafe. Install it on the server. EXPRESSCLUSTER WebManagerThis is a tool to manage EXPRESSCLUSTER X SingleServerSafe operations.It uses a Web browser as a user interface. The WebManager is incorporated into theEXPRESSCLUSTER Server and therefore does not have to be installed. EXPRESSCLUSTER Builder (Builder)This is a tool for creating the configuration data of EXPRESSCLUSTER XSingleServerSafe. There are two versions. The online version Builder runs in theconfiguration mode of the WebManager, and the offline version Builder is installedindividually in a management terminal. The online version Builder is incorporated in theWebManager. The Builder also uses a Web browser as a user interface the same way as ilderWebManager(Browser)ServerManagement PCThe EXPRESSCLUSTER X Builder and the WebManager are Java applets that run on Java VM.They can run on any machine in which the Java Runtime Environment (JRE) is installed.In other words, once you install the JRE on a server on which EXPRESSCLUSTER XSingleServerSafe is installed, you can use the Builder and WebManager on that server.15
