Unified desktop licenses are type of licenses used by TSAPI - typically for Microsoft Office Communicator (MOC) or IBM Sametime users. These users connect to AE Services via DMCC, but their licenses are controlled by TSAPI. Thus, like the TSAPI basic user licenses mentioned in the previous section, accessing the WebLM server for each license request can have a noticeable effect on performance. For example, if your LCS, OCS, Lync, or IBM Sametime server initiate monitors for hundred MOC or for hundred IBM Sametime users, the TSAPI Service will normally acquire a license from the WebLM server, for each of these users, one at a time. You can reduce the time by reserving unified desktop licenses. When you reserve unified desktop licenses, the TSAPI Service acquires all of the reserved licenses at startup time by making a single request to the WebLM server. If more than the reserved amount of unified desktop licenses are used at any given time, TSAPI will acquire the extra licenses from the WebLM server, one at a time.
After installing or upgrading to AE Services 6.3 or later, use this procedure to:
Ensure the TSAPI Service starts successfully after a system reboot.
Optimize the performance of the TSAPI Service.
