load distribution method in large capacity report treatment process of DCS

摘要

PURPOSE: A large volumed report processor load distribution method is provided to solve an overload or a time delay caused by processing large volumed event and alarm data in a system. CONSTITUTION: The method comprises steps of placing a process at an administration shelf for reporting a message of an alarm and an event, enabling the process placed at the administration shelf to analyze the message if the message is reported to the administration shelf, generating a process in charge of the message, moving the message to the process in charge of the message, enabling the process in charge of the message to process the corresponding message, and storing the processed data at a database or processing a series of other operation on the processed data. In a step of generating a process in charge of the message, some tokens are generated for enabling two more processes to process the same message. If the process is completed, the tokens are withdrawn and then allocated at the next processes. Large volumed report data can be speedily processed by simultaneously activating a plurality of processes. A system resource usage efficiency can be enhanced by limiting the number of the generated processes.
