To connect to a QlikView Server (QVS), each client needs its own license. Those can either be Analyzer or Professional Licenses - or a Client Access License (CAL).
CALs are part of our legacy licenses, which are licensed with a serial number and control number. The CALs are purchased with QlikView Server and tied to the server serial number.
A CAL is never transferred to a client, but a client uses the CAL when connecting to the server or, if a cluster license is used, a specific QlikView Server cluster. CALs cannot be transferred between different QlikView Server clusters.
If a user is required to work with documents residing in different clusters, a separate CAL is needed for each of the clusters.
Note! The CALs require the QlikView Servers within a cluster to be within the same geographical and physical location and within the same network sub-net/segment.
