Redundant Licence Servers

A licence server can be backed up using redundant licence servers.

In this method licences are shared amongst servers. This simply means if the primary licence server fails a secondary server can step in automatically.

Things to remember

All redundant licence servers at a site form a licence server pool. Each server in the pool can take over from any other server in case of failure.
Up to 11 licence servers can be used to provide licence server redundancy (however a minimum of three must be used).
The number of redundant licence servers and the specific machines on which they reside should be decided prior to licences being created. A number of factors (including network performance) will affect this decision. (Please speak to your IT department.)
Licence servers will be locked to specific computers; ensure you have provided 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.
