The application program uses MSL and communicates with the license server.
The lmgrd daemon handles initial contact with the client application programs and passes the connection to the appropriate vendor daemon. The lmgrd daemon also starts and restarts the vendor daemons.
Node-locked uncounted (mobile compute) licenses do not require lmgrd or mgcld.
The Mentor vendor daemon, mgcld, keeps track of the licenses that are checked out. If the mgcld process terminates for any reason, all users lose their licenses but usually regain them automatically when lmgrd restarts mgcld.
The license file is a text file where FlexNet stores licensing data. Mentor creates this license file, which contains information about the server and mgcld and at least one line of data, called the INCREMENT line, for each licensed product.
Each INCREMENT line contains an encryption code that is based on data on that line, the host ID of the server(s), and other Mentor-supplied data such as expiration date, count, and version.
For details about the license file’s contents, see “License File Format”.
For more information about FlexNet components, refer to the FlexNet Publisher License Administration Guide published by Flexera Software.
Mentor uses FlexNet certificate-based licensing only.
