#Flexlm licensing software#
If your site has software from multiple vendors with incompatible license files (due to different sets of servers), keep the data in separate files and set the LM_LICENSE_FILE variable to reference multiple files. Override this location by setting the environment variable LM_LICENSE_FILE to point elsewhere, or by following instructions supplied with the licensed application. Most applications have an expected location for the license file, documented by that application. FLEXlm-licensed applications that are licensed with a node-locked, uncounted license need only read a valid license file to run-they do not need a license server.
#Flexlm licensing license key#
Each FEATURE line contains a license key or signature based on the data in that line, the hostids specified in the SERVER line(s), and other vendor-specific data. It contains information about the server machines and vendor daemons, and at least one line of data (called FEATURE or INCREMENT lines) for each licensed product. The license file is created by the software vendor, and edited and installed by the license administrator. Licensing data is stored in a text file called the license file. This behavior is defined by the vendor in the FLEXlm-licensed application. Users normally regain their license automatically when lmgrd restarts the vendor daemon, though they may exit if the vendor daemon remains unavailable. If the vendor daemon terminates for any reason, all users lose their licenses (though this does not mean the applications suddenly stop running). This means the license server and the computer running an application can be either different hardware platforms or even different operating systems (Windows and UNIX, for example). Also, the format of the traffic between the FLEXlm-licensed application and the vendor daemon is machine independent, allowing for heterogeneous networks. The FLEXlm-licensed application and the daemon processes (the license server) can run on separate machines on your network, across any size wide-area network. The vendor daemon keeps track of how many licenses are checked out, and who has them.įLEXlm-licensed applications communicate with the vendor daemon, through TCP/IP network communications. This process is called the vendor daemon. There is one process for each vendor who has a FLEXlm-licensed product on the network. In FLEXlm, counted (floating) licenses are granted by processes running on the system. It also starts and restarts the vendor daemons.Ĭhapter 6, “The License Manager Daemon,” contains information for configuring and starting the license manager daemon in your environment. The license manager daemon ( lmgrd) handles the initial contact with the FLEXlm-licensed applications, passing the connection on to the appropriate vendor daemon. The licensed application and license certificate reside on the same machine.
#Flexlm licensing manual#
This manual is written for two different audiences:įigure 1-2: FLEXlm Unserved License Component Model See Section 2.3, “Types of License Files,” for details about the different licensing models supported by FLEXlm. License administrators control who uses the licensed application and the machine(s) where the licenses are available. Users make more efficient use of fewer licenses by sharing them on the network. Floating licensing benefits both users and license administrators. FLEXlm is best known for its ability to allow software licenses to be available (or float) anywhere on a network, instead of being tied to specific machines.
#Flexlm licensing how to#
Section 1.6, “Getting Started Checklist,” tells both license administrators and end users how to start managing FLEXlm.įLEXlm is the most popular license manager used in the software industry. It explains where license administrators have control and where end users have control. This chapter explains the basics of floating (network) licensing and gives a quick overview of the components of FLEXlm.
