Types of Licenses Available

Various types of licenses can authorize Mentor applications, and each has specific characteristics.

Floating

  • Anyone on the network can use the license. The licenses are tied to a server host ID provided by a system host ID, network interface, or hardware key.

  • A license server is required. The license server tracks how many licenses are available and how many are currently in use. You can use the options file to configure license servers to allow access only to certain groups or individuals.

  • Licenses must be served from the computer whose host ID matches the host ID listed on the SERVER line of the license file.

  • The license file contains both a SERVER and DAEMON line, and the quantity on each INCREMENT line is greater than zero (0).

Node-Locked Uncounted (Mobile Compute)

  • For Windows only.

  • The license is locked to a particular piece of hardware, either an Ethernet address or hardware key, and the hardware must be installed and operational for the license to work.

  • The license file does not contain SERVER or DAEMON lines, and the quantity on each INCREMENT line is zero (0). “Zero” identifies this as a special kind of license, not that licenses are unavailable.

  • A license server is not required.

Node-Locked Counted

  • The license is locked to a particular piece of hardware, either an Ethernet address, host ID, or hardware key. The devices provide a unique identifier for the license.

  • The software runs only on the system that has the particular piece of hardware installed.

  • A license server is required. The license server tracks how many licenses are available and how many are currently in use. You can use the options file to configure license servers to allow access only to certain groups or individuals.

  • The license file contains both a SERVER and DAEMON line, and the quantity on each INCREMENT line is greater than zero (0).

  • The license must be served from the computer whose host ID matches the host ID on the SERVER line of the license file.

  • The difference between floating and node-locked counted licenses is that node-locked counted licenses have a host ID field (HOSTID=) on each INCREMENT line.
