On a virtual machine, however, the hardware is virtual, and the information the lock code is built from can often change when the virtual machine is un-deployed and re-deployed. On a physical machine, a hardware-based lock code and thus this unique identifier is preferable because it changes only if that piece of physical hardware is changed - swapping out a NIC, for example The lock code is a unique identifier associated with the machine - typically-but-not-always hardware-based, such as an Ethernet card. Licenses are tied to the machine running the license manager with a lock (or 'locking') code. Licensing the license manager in a virtual environment There are no special instructions for installation.
This tech note provides special instructions for licensing the license manager in a virtual environment. When users on the same network start an IBM SPSS application, the application communicates over the network and retrieves a license from the license manager. It is installed on a physical or virtual computer that is connected to your network. The concurrent license manager is a utility that serves concurrent licenses to SPSS users.
