SySAM consists of two utilities, called lmgr and lmutil, which manage licensing activities, and two background processes: the license management, lmgrd, and SYBASE. The SySAM lmgrd daemon or service contains a pointer that locates the license file for verification and can reside either on the primary server, known as the local license host, or on a remote license host. The daemons or services handle requests to validate licensed features, as shown in Figure 2-1.
The following is an illustration of the relationship between these components, on UNIX.
Figure 2-1: How SySAM interacts with DirectConnect
Using information in the license file, DirectConnect connects to the SySAM daemon and attempts to check out a license for the base DirectConnect product. If the DirectConnect license is checked out successfully (a license exists in the license file), DirectConnect continues to operate.
If a DirectConnect license is not found, it continues to operate, but it does record this discrepancy.
For Windows only, if you have not registered a license for each service, a pop-up warning will appear for each service, each time that you activate the service. You can enter your license to prevent this from occurring or select cancel, to continue.
