Stop the license server via Start / Control Panel / Administrative Tools / Services / CADENAS FLM (MASTER).
Remove the service via Start/ Control Panel / Programs and Features.
The files in the installation path (default C:/cadenas_flm) are automatically deleted. Empty directories can be manually deleted.
If a V9.03 (or higher) and a V8.1 FLM Server shall be used combined (on an interim basis), then these have to be setup on different servers.
Client and FLM Server with different software versions
If Client and FLM Server have different software versions, then please regard the following:
Combination V8.1 Clients == V9.03 FLM Server
The server can handle "old" license packages as well and distributes the according V8.1 packages to the clients.
The Checkout function (see Section 7.6.1.5, “"Checkout" tabbed page” in PARTsolutions - User manual) is not available for V8.1 Clients.
A Master Backup cluster of V8 and V9 FLM servers is technically not possible.
A Master Backup cluster exists of 2 or more V9 FLM servers.
In the license file both hostids (MASTER and BACKUP) have to be declared.
In the case of malfunction the BACKUP FLM server takes the place of the MASTER FLM server. Working in the backup mode is possible up to 12 hours.
Still more secure is to use three V9 FLM servers. Then unlimited working is possible as long as 2 from 3 servers are available. Also in this case all 3 server hostids have to be declared in the license file.
Information concerning setup of a master backup cluster can be found under Section 1.4.4.1, “ "Connected servers" dialog area ” in PARTsolutions - Administration Manual.
