A license daemon (lmgrd) runs on one or more systems somewhere on your network. These systems are called license servers. The license daemon accesses a license data file named license.dat, which contains information on your licenses and your license servers. Each system on which Builder Xcessory executes must have the license.dat file available to it, either by way of an NFS-mount or by having a local copy of the file.
When you run Builder Xcessory, it looks in the license.dat file for the license server(s) and it requests a license from lmgrd on the listed server(s). If a license is available, the program runs normally. If no license is available, Builder Xcessory runs in demo mode.
The license.dat file is created when you install FLEXlm. Typically, the license.dat file is placed in the /usr/local/flexlm/licenses directory, often a directory accessible by all systems on the network.
