After installing or upgrading to AE Services 6.3 or later, perform this procedure to:
make sure the DMCC Service starts successfully after a system reboot.
optimize the use of the DMCC licenses.
Like the TSAPI Service, the DMCC License Service acquires its licenses from the WebLM server. DMCC licenses are used to register a DMCC endpoint (station) with Avaya Communication Manager for first-party call control. A DMCC license is required for each endpoint that is registered through DMCC.
Depending on the nature of your DMCC application and the number of endpoints it registers via DMCC, accessing the WebLM server for each license request can have a noticeable effect on the performance of your application. For example, if your DMCC application registers one or more endpoints for each of several hundred telephone extensions, the DMCC License Service will normally acquire a license from the WebLM server for each of these endpoints. Each license request to the WebLM server will be completed one license at a time.
You can reduce the time it takes your DMCC application to register these endpoints by reserving DMCC licenses. When you reserve DMCC licenses, the DMCC License Service acquires several licenses at the time of the first registration by making a single request to the WebLM server. One license will be allocated immediately for the initial registration, while the rest of the licenses will be held in reserve for future registrations. If more licenses than the specified reserve amount are required (that is, there are more concurrently registered endpoints than reserved licenses), then another increment of DMCC licenses (equal to the reserve amount) will be acquired from the WebLM server. License acquisition is performed in increments of the specified reserve amount up to the maximum number available on the WebLM server. Similarly, as endpoints are unregistered, the freed licenses will be released back to the WebLM server in similar increments (equal to the reserve amount). Note that when the last endpoint is unregistered, all of the remaining reserved DMCC licenses will be released back to the WebLM server.
