OpenLM 1.5.0 support FLEXnet redundant server configuration

What is a redundant server configuration with FLEXnet?

A redundant server is used in order to insure the availability of floating licenses, in the event of a system crash. Redundant server configuration is created with a minimum of three servers. For as long as at least two servers are working, licenses will remain available to users. If only one server functions, licenses will not be available since a "Quorum" of at least two is required.

How do I set a redundant server configuration?

You need to ask your software vendor to supply you three license files with the same features, one for each machine.

Is there an alternative configuration?

Yes, you can split up your licenses between multiple independent servers. In this case the software will use licenses from any available license server. The disadvantage of this configuration is that your efficiency will decrease. Also, if one server goes down, the total amount of licenses available will decrease according to the number of licenses on that server.

How can I configure OpenLM server to work with redundant server configuration?

Just add all the three redundant servers to OpenLM monitoring list, by using the OpenLM server configuration form. OpenLM will monitor all three servers and continue to work even if one of the servers will crash. OpenLM server will know to collect your license statistics as if you operated a single license server.
