Abstract

특정노드와 다수의 일반노드를 구비한 분산노드 구조시스템에서 각 노드별 데이타 베이스를 동시에 변경하는 방법에 관한 것이다.The present invention relates to a method of simultaneously changing a database for each node in a distributed node structure system having a specific node and a plurality of general nodes.

상기 특정노드에서 데이타 베이스 변경 명령을 감지하여 데이타 베이스 변경을 예약등록하고 상기 다수의 일반노드로 데이타 베이스 변경명령을 송신하면, 상기 다수의 일반노드에서 상기 데이타 배이스 변경명령을 수신하고 데이타 베이스 변경을 예약 등록함으로써, 상기 특정노드와 다수의 일반노드에서 예약 등록한 시간이 되면 동시에 데이타 베이스를 변경하는 동작을 독립적으로 실시하여 노드간 통신의 신뢰성을 높인다.If the specific node detects a database change command and reserves and registers a database change command, and sends a database change command to the plurality of general nodes, the plurality of general nodes receive the data base change command and perform database change. By reservation registration, when the time registered by the specific node and a plurality of general nodes reaches the time of reservation registration, the operation of simultaneously changing the database is independently performed to increase the reliability of inter-node communication.

Claims (3)

특정노드와 다수의 일반노드를 구비한 분산노드 구조시스템에서 각 노드별 데이타 베이스 변경 방법에 있어서, 상기 특정노드에서 데이타 베이스 변경 명령을 감지하여 데이타 베이스 변경을 예약등록하고 상기 다수의 일반노드로 데이타 베이스 변경명령을 송신하는 과정과, 상기 다수의 일반노드에서 상기 데이타 베이스 변경명령을 수신하고 데이타 베이스 변경을 예약 등록하는 과정과, 상기 특정노드와 다수의 일반노드에서 예약 등록한 시간이 되면 동시에 데이타 베이스를 변경하는 동작을 독립적으로 실시하는 과정으로 이루어짐을 특징으로 하는 데이타 베이스 동시 변경 방법.A method for changing a database for each node in a distributed node structure system having a specific node and a plurality of general nodes, wherein the specific node detects a database change command and reserves and registers a database change and sends data to the plurality of general nodes. Transmitting a base change command, receiving the database change command from the plurality of general nodes, and registering and registering a database change; and at the same time when the reservation time is registered between the specific node and the plurality of general nodes A method of simultaneously changing the database, characterized in that the process is performed independently to change the operation. 제1장에 있어서, 상기 특정 노드에서 타 노드로 데이타 베이스 변경 명령을 송신하는 과정 수행후 예약 시간이 될때까지 상기 타 노드로 부터의 응답 유무를 체크함을 특징으로 하는 데이타 베이스 동시 변경 방법.The method of claim 1, wherein the presence or absence of a response from the other node is checked until a scheduled time is reached after the process of transmitting a database change command from the specific node to the other node. 제2항에 있어서, 상기 다수의 일반 노드에서 데이타 베이스 변경을 예약 등록하는 과정 수행후 명령을 보낸 노드로 응답을 송신함을 특징으로 하는 데이타 베이스 동시 변경 방법.3. The method of claim 2, wherein the plurality of general nodes transmit a response to the node that sent the command after performing the process of pre-registering the database change. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
