Acucorp's thin client solution follows a server licensing model. The ACUCOBOL-GT Thin Client, which is installed on client machines, is available as a download on Acucorp's Web site or on your Acucorp CD-ROM or a floppy disk. You are required to accept a clickwrap license agreement on installation. On the server, you must install an AcuLaunch license file that accommodates the number of concurrent thin client users that you anticipate. You also need a runtime license file that accommodates the maximum concurrent thin client users plus any local runtime users.
When AcuLaunch detects a client request to start a remote application runtime, it checks the connection count to see if another connection is permitted. If another connection is allowed, AcuLaunch attempts to start a runtime on the server and connect it with the client process. The runtime, in turn, checks its usage count before it begins execution of your application. When a thin client user disconnects from the remote server by exiting the COBOL program, the AcuLaunch and the runtime usage counts are decremented and those slots are made available to subsequent users. If the usage limit has been reached, the server runtime is not started and an appropriate message is returned to the end user.
