Overview - FlexNet

FlexNet licensing makes use of a license file, rather than a license key, to enable MathFlow SDK components. This can be especially useful when deploying an application containing MathFlow Components to many users. Design Science provides three types of MathFlow FlexNet licenses: Evaluation, Fixed Permanent, and Concurrent (or Floating). If you require Concurrent licensing, then FlexNet-type licenses are required. Depending on the license type, the license file may be located on the same machine that MathFlow is running, or it may be accessible via a central license server on your network (in the case of concurrent licenses).

Evaluation License

An Evaluation license expires on a specific date, which is determined by the date that the license was generated by Design Science. This type of license is most commonly used for demonstrations and evaluations of the product. See Evaluation License for more information on evaluation licenses, including how to obtain one.

Fixed Permanent License

A Fixed Permanent license is one of two permanent license types that can be used with MathFlow. The fixed license is tied to a specific computer. Upon sending a "hostid" from the machine, Design Science will send back a license that works only on that machine. See Permanent License for information on how to locate your hostid.

Concurrent License

A MathFlow Concurrent (or floating) license uses a license server. When you send in your server's IP address and "hostid," Design Science will send back a license file tied to that IP address. You can then place copies of the license file on the license server and all client machines (these copies tell the client where the server is). When a client machine needs a license, it contacts the server and "checks out" the license. When the license is no longer required, it is checked back in. With this approach, several people can share a single license, provided they don't use it at the same time. See Permanent License and License Server.
