The system.properties file contains properties that relate to the Dashboard including the proxy server configuration, default language, and default time zone. This file is never modified at any time.
Instead, a /OperationsCenter_Dashboard_install_path/server/webapps/ROOT/WEB-INF/classes/system-ext.properties file is used to override setting, when necessary.
WARNING:Exercise caution when modifying the system-ext.properties file. Do not change any properties unless you are fully aware of the consequences. Changing some properties could cause conflicts with the Operations Center server and can have unintended consequences.
To configure the systems property file:
For the Dashboard to recognize the system-ext.properties file, open the \OperationsCenter_Dashboard_install_path\bin\catalina.bat (Windows) or the /OperationsCenter_Dashboard_install_path/bin/catalina.sh (UNIX) file.
Add the following line to the set JAVA_OPTS property:
-Dsystem.properties.load=true
