The System Available task allows you to control whether the system is set to available (online) or not available (not online) status. You can set the system to a not available status, then run some tasks, and set it back to an available status using this task. You can add this task to your package by registering OSoftTaskAvailable2008.dll located in the BPC\websrvr\bin folder, with the Microsoft SSIS interface. See Registering Custom Tasks.
