Skyline Floating License Server

The license information can also be obtained using a floating license server which enables a number of licenses to be shared among a larger number of users. When an authorized user wants to run SGS, the user requests a license from the license server, and if one is available, the license server allows SGS to run. When the user finishes running SGS, the license is returned to the license server for use by other users.

When SkylineGlobe Server is running in a server cluster, all servers in the cluster share a single license, i.e., only a single license needs to be requested from the license server. The first server that is activated borrows the floating license, and shares it with the cluster. If the first SGS stops for any reason, the license is automatically released from that SGS and transferred to a different server who shares it with the cluster. This happens without interruption so that machines can be dynamically added and removed from the cluster, without requiring a separate license for each. In addition, the maximum number of concurrent active end users defined in the license is shared between all the cluster servers, with the load balancer determining the distribution of server traffic between the servers.

Note:    The same license file should be used for installation of SGS on all machines in a server cluster.
