The SySAM network license server has the following limitations:
You cannot start the SySAM network license server until there is at least one “Served” license copied into the %SYBASE%\SYSAM-2_0\licenses directory. Obtain a “Served” license from the Sybase Software Product Download Center before starting the license server. See “Managing licenses”.
SQL Expert version 15.0.2 uses the SySAM 2.0 licensing technology. On any one machine, you can have only one instance of a license server running. You must make some adjustments to use earlier versions of SySAM with SQL Expert 15.0.2. See “Co-existing with earlier versions of SySAM”.
