One of the most effective ways of managing the client scheduler is to use the Tivoli® Storage Manager Client Acceptor service (CAD). You must configure the client to use the client acceptor service to manage the scheduler.
The CAD serves as an external timer for the scheduler. When the scheduler is started, it queries the server for the next scheduled event. The event is either run immediately or the scheduler exits. The CAD restarts the scheduler when it is time to run the scheduled event. This action reduces the number of background processes on your workstation and resolves memory retention problems that can occur when the scheduler is run without CAD management.
The client acceptor service is also known as the client acceptor daemon.
