The configuration required for Tivoli Enterprise Portal clients depends upon the client deployment mode being used, the browser being used, the Java™ runtime environment (JRE) being used, and the operating system the client is being used on.
The version of IBM® JRE required by Tivoli Enterprise Portal clients is installed with Tivoli Management Services components. If you want to run a client on a machine where no other components are installed, you can download the IBM JRE installer from the Tivoli Enterprise Portal Server. On Windows, the IBM JRE must be installed as the system JVM if you plan on using the browser client.
The packaging, installation, and servicing of the Oracle JRE is not provided by IBM. The Oracle JRE at version 1.7.0.xx must already be installed on the machines where the Tivoli Enterprise Portal client will run. The Oracle JRE can be downloaded from the following Web site: http://www.oracle.com/technetwork/java/archive-139210.html. For help installing the Oracle JRE, visit the following Web site: http://www.java.com/en/download/help/index_installing.xml.
The IBM Tivoli Monitoring installer does not use the system JRE. Instead it installs a local copy of Java, one that is private to Tivoli Monitoring. This applies to all Java-dependent Tivoli Monitoring components.
This embedded JRE is installed in the %CANDLE_HOME%\java directory under Windows, and the %CANDLE_HOME/JRE directory under Linux. The system Java is untouched by the IBM Tivoli Monitoring installer.
Under Windows, the browser client and Java Web Start still use the system JRE. For your convenience, the IBM JRE installation image is distributed as part of the browser client package.
The desktop client uses the embedded JVM by default.
The IBM Tivoli Monitoring installer does not install an embedded JVM if none of the components selected for installation has a Java dependency.
