System home

Sometimes identified by its alias, niagara_home, the system home is the sole location to which the Workbench installation wizard and platform commissioning wizard install Niagara runtime components, such as core software modules, the JRE, and binary executables. License files and license certificates reside in the Workbench system home, under the security subfolder. A system home contains no configuration files that can be changed by a user. Except when it is time to upgrade, these runtime files are read-only.

The example above shows the file system for Niagara 4 Supervisor running on a Windows PC. In the Nav tree, the system home folder is referred to as its Sys Home. In the Platform Administration view, the same system home is referred to as System Home.

In the example, the actual location of the system home folder on this PC is: C:\niagara\niagara-4.7.109.14.

The system home on a controller appears as System Home in the Platform Administration view. The actual location of the system home folder for a controller is: /opt/niagara/opt/niagara.
