License manager daemon, lmgrd
Learn about the lmgrd daemon, which is
used to manage floating licenses.
Two daemons (or processes) are used to manage floating licenses:
- lmgrd, the license manager daemon.
- ibmratl, the vendor daemon.
The lmgrd daemon and the vendor daemons work together to manage the license keys. The lmgrd daemon handles the initial contact with the client application programs, passing the connection on to the appropriate vendor daemon. The lmgrd daemon also starts and restarts vendor daemons.
By default, the lmgrd daemon on Windows is a Windows service.
The lmgrd daemon starts on TCP/IP port 27000 by default when you start the server. If a firewall is not configured, lmgrd assigns a random TCP/IP port number to the vendor daemon and starts the vendor daemon on that port.
