Licensing requirements for cluster nodes
Each cluster node requires its own license, so activate a separate serial number for every node. Restart the stations after the service switches between cluster nodes. The Processing Server stops and then starts again automatically after 5 minutes.Page use statistics across nodes
Each cluster node writes its own log file of page use statistics to%allusersprofile%\ABBYY\FlexiCapture\12\Licenses.
The program decrements the page counter of the license belonging to whichever node is running. To get overall page use statistics, add up the pages consumed by every node involved in the processing.
