License Manager Redundancy API
The License Manager redundancy allows the total number of licenses to remain available to the enterprise even if one or more License Managers fail. If a License Manager fails, the license tokens it is serving will be taken over by the next-available License Manager. For information on setting up and using redundant License Managers, refer to the Sentinel RMS SDK Developer Guide and the Sentinel RMS SDK System Administrator Guide.
