If you are using a serverless configuration, the local %SYBASE%\SYSAM-2_0\licenses directory should contain all necessary licenses. You do not maintain a license server.
When you use a serverless configuration, you must activate the licenses for each machine separately; that is, you do not have centralized control over your licenses. You also do not have asset management or reporting capabilities, and your license must be rehosted if you move Database Expert from one machine to another.
