This section describes the Java Runtime Environment (JRE), and how to distribute and install it for the various supported platforms.
Where a JRE is provided by MainView Middleware Monitor for a particular platform, dependent components are configured to look for the JRE in a default location relative to their directory (based on the Default Layout). Since this section presumes you have selected the Flat Directory Layout, or have more complicated environments, you should set the JAVA_HOME environment variable to point to the correct location for the JRE.
Depending on the monitored technology, it might not always be appropriate to use the provided JRE. In those cases, set a JAVA_HOME environment variable for that particular monitoring extension so that it uses the appropriate JRE.
Where a JRE is not provided for the platform, one must be available for those components that require it. In those cases the JAVA_HOME environment variable must be set to indicate where a JRE can be found.
When setting JAVA_HOME in your environment, consider the monitoring environment as a whole. Your monitoring requirements might call for multiple Java versions to be available, or multiple JREs configured with different settings (e.g. for security configuration purposes).
To install the JRE for those platforms where a JRE is provided, follow the steps below.
In the command prompt, change to the directory where the MVMM Agents and Extensions are installed.
Unzip the contents of the pkg_jre_.zip* package, as appropriate for your platform, to a sub-directory of the MVMM Extensible Agent (e.g. into a directory named jre).
