Redundant Licence Servers

Licence server backup is provided by using redundant licence servers.

This is the fail safe method where licences are shared amongst servers so that in the event of a failure of the primary licence server a secondary server will take on the role of primary licence server.

Using this method all of the redundant licence servers at a site form a licence server pool. Each of the licence servers in the pool can take over for any other if one of the licence servers should fail. Each licence server runs on a separate computer on the network.

Up to 11 licence servers can be used to provide licence server redundancy, however a minimum of three must be used.

A decision on how many redundant licence servers to set up and select the computers on which they will reside must be made prior to licences being created. A number of factors, including network performance, will affect this decision.

Licence servers will be locked to specific computers; therefore you must provide Cadcorp with the locking code for each computer on which a redundant licence server is to be installed.

If Server 1 fails licences are transferred to Server 2:

This process will be repeated up to Server n.
