Abstract
본 발명의 클라이언트 및 서버 프로세스의 트랜잭션 동기 처리방법은 클라이언트 프로세스와, 서버 프로세스가 하나의 트랜잭션을 처리할 경우에 트랜잭션 종료 및 트랜잭션 취소를 동기적으로 처리할 수 있도록 하는 것으로서, 종래에는 트랜잭션 종료 및 취소할 경우에 클라이언트 프로세스 및 서버 프로세스 간의 트랜잭션 처리 과정의 동기를 맞추기 위하여 메시지를 사용하고, 트랜잭션의 종료처리시에는 서버 프로세스의 종료 준비상태를 확인하기 위하여 커널이 종료요청 메시지를 기다려야 되었으며, 트랜잭션의 취소처리시에는 취소신호와 메시지의 전달을 통해 상호간에 트랜잭션의 처리를 동시에 처리할 수 있도록 하고 있는 것으로 메시지를 통해 클라이언트 프로세스와 서버 프로세스의 트랜잭션 종료 및 취소시 상호간에 동기를 맞추기 위해서는 커널에 메시지의 송신 및 수신기능이 구현되어 있어야 되나, 메시지의 송신 및 수신 기능은 특정 시스템에만 구현되어 있는 것으로 트랜잭션의 처리 기능을 커널에 구현할 경우에 적용하기가 매우 어려웠다.The transaction synchronous processing method of the client and server process of the present invention enables the client process and the server process to process transaction termination and transaction cancellation synchronously when processing one transaction. In this case, the message is used to synchronize the transaction processing process between the client process and the server process.In the process of transaction termination, the kernel has to wait for the termination request message to confirm the readiness of termination of the server process. When processing, it is possible to process transaction mutually simultaneously by delivering cancel signal and message.Matching synchronization between client process and server process through message through synchronization In order to send and receive messages in the kernel, it is necessary to send and receive messages. However, the sending and receiving of messages are implemented only in a specific system. Therefore, it is very difficult to apply a transaction processing function to the kernel.
발명은 트랜잭션의 자료 구조에 2바이트의 비트 플래그를 구비하고, 클라이언트 프로세스 및 서버 프로세스가 트랜잭션을 처리할 경우에 트랜잭션의 처리상태를 비트 플래그에 표시함으로써 클라이언트 프로세스 및 서버 프로세스가 비트 플래그의 세트상태로 상호간에 진행상태를 판별하여 트랜잭션의 종료 및 취소 과정을 동기로 처리할 수 있다.The invention includes a two-byte bit flag in the data structure of a transaction, and when the client process and the server process process the transaction, the client process and the server process are brought into the set state of the bit flag by displaying the transaction status in the bit flag. By determining the progress of each other, the transaction termination and cancellation process can be processed synchronously.
