Patent ID: 7136864

Claim:
A database table modeling and an event handling method for a real time management in a network alarm management system including an alarm management processor, a client list table, an alarm database, a daemon processor managing abnormally-completed clients, a listener table, and a plurality of alarm managers, comprising the steps of: storing alarm information in an alarm database by the alarm management processor, when an alarm event is generated from a network system equipment; polling the alarm information stored in the database in correspondence to an alarm sequence number by the alarm managers, and storing polling-related information on the client list table when the polling process is completed; and managing a current alarm list of the listener table by mapping a certain amount of current alarm information accumulated on the listener table with a reading alarm sequence number of the client list table by the daemon processor, and managing abnormally-completed clients by recognizing a state of the client list table with a last polling time and the alarm sequence number, said alarm managers performing the steps of: recording self driving time information on the client list table during an initial driving process; and reading a self-polled last sequence number from the client list table, and polling alarm information including a bigger value than the last sequence number among alarm sequence numbers existing on the listener table.
