제1도는 본 발명이 적용된 트랜잭션 처리시스템의 전체 구성을 나타낸 블록도, 제2도는 트랜잭션 처리시스템의 트랜잭션 모델.1 is a block diagram showing the overall configuration of a transaction processing system to which the present invention is applied, and FIG. 2 is a transaction model of a transaction processing system.

Claims (1)

복수의 프로세스가 클라이언트와 서버의 관계를 이루는 다중 트랜잭션 처리시스템의 공간버퍼 관리방법에 있어서, 버퍼쓰기를 요구하면 로그 레코드가 플러쉬 되지 않은 경우 로그 레코드를 플러쉬 하고 디바이스 스트레터지를 호출하는 단계와, 싱크모드이면 I/O가 끝날때까지 기다리고 버퍼를 해제한 후에 변환하고, 만약 싱크모드가 아니면서 지연 쓰기 버퍼이면 버퍼오류 검사를 한 후에 반환하는 단계와, 로그 I/O의 인터페이스 구조를 검사한 후에 물리 로그 I/O를 위한 버퍼 헤더의 내용을 설정하고 요구한 I/O블록 수만큼의 내용이 들어갈 커널 영역을 할당하는 단계와, 만약 읽기이면 상기 다비이스 스트레터지를 호출하여 슬립하고, 읽은 내용은 버퍼에 기록한 후에 반환하는 단계와, 읽기가 아니면 각 버퍼의 내용은 커널영역에 복사하고, 상기 디바이스 스트레터지를 호출하여 싱크 여부를 확인하여 싱크가 아니면 반환하고, 싱크이면 슬립한 후에 반환하는 단계를 포함하는 것을 특징으로 하는 트랜잭션 처리시스템의 공간/버퍼 관리방법.A method of managing a space buffer in a multiple transaction processing system in which a plurality of processes form a relationship between a client and a server, the method comprising: flushing a log record and invoking device strategy when the log record is not flushed when a buffer write is requested; In mode, wait until the end of the I / O, release the buffer, and then convert.If the write buffer is not in sync mode, return to the buffer after error checking, and check the interface structure of the log I / O. Setting the contents of the buffer header for the physical log I / O and allocating a kernel area for the content of the requested number of I / O blocks; if reading, call the device storage to sleep, and read the contents. Returns to the buffer after writing to the buffer. If not, the contents of each buffer are copied to the kernel area. Vice host letter called to check whether the synchronization is not returned to the sink, and the sink is space / buffer management method of the transaction processing system comprising the step of returning, after a slip paper. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
