What is the License Controller?

The License Controller is a license management tool for controlling product licenses.

A License Controller is installed with your Genero product. The license controller responds to requests for licenses when a Dynamic Virtual Machine (DVM) process is started. It determines if a license is available, based on the number of users allowed by the license and the number of licenses actively in use. When a DVM stops, the license controller releases the license.

You use the license controller's command line program (fglWrt or greWrt) to install and manage your licenses.
Tip:
