  • ExecutionManager

    v10 v11  
    77== Introducion ==
    88The Execution Manager executes Execution Plans that the SQR created as a result of requests from Resource Users. The requests are either for retrieving information or executing actuation tasks. As the Figure shows, the Execution Manager consists of two logical internal components, the Request Management that executes the Execution Plan and the Request Monitoring that monitors the request execution in case of long-term requests.

     10=== Request Management ===
     11The Request Management executes short term requests received via the requestInformation operation as well as long term requests received via the requestSubscription or updateSubscription operations. The Request Management will process the requests and in the first case return information received from the Resources and in the second case set up sessions between Resources and Resource Users.

     13=== Request Monitoring ===
     14The Request Monitoring monitors the availability and reliability of REPs in order to provide a good quality of long term requests. After set up the a long term subscription by the Request Management, the  Request Monitoring will set up the needed subscriptions to monitor the intended resources. When the Request Monitoring is notified that a change happened, it will notify the requesting ressource user.
