If you want to use a standalone served or a floating served license, you must have access to a license server. Licenses for all Sybase products can be managed by a SySAM license server, which is powered by Flexlm technology, and is available on the PowerDesigner CD-ROM.
The default SySAM server supplied with PowerDesigner can only be installed on a Windows machine. To install SySAM in other environments and to obtain detailed information about SySAM, go to http://www.sybase.com/sysam. Note that any licenses that have been activated for a Windows server must be reactivated for any other platform.
The license server serves a license to a user upon request and retrieves it when it is no longer being used. If all the licenses are already in use, the license server informs you that no license is available.
