Abstract

There are many methods to enhance the fault tolerance of the CORBA based real time systems by viewpoints. Among them, this paper provides a method to enable seamless services where the systems based on the CORBA have object's faults originated processing real time information. Namely, this paper observes a method to deal efficiently with object's faults happening in 3 tier architecture environments. It is possible to replicate objects as a way to enhance the fault tolerance considering object's faults. Along with it, this paper shows a method to enhance the fault tolerance ultimately and then keep the service continuity by prividing a way to allow to continue to run the systems until the FT-CORBA based one's faults are recovered.

CORBA를 사용하는 실시간 시스템의 안정성을 높이기 위한 방법은 관점에 따라 여러 가지가 있다. 그 중에서 본 논문은 CORBA 표준을 구현한 시스템이 실시간 정보를 처리할 경우 발생하는 객체 장애 시에 지속적인 서비스를 가능케 하는 방법을 제시한다. 즉, 3 tier 소프트웨어 아키텍쳐 환경에서 발생하는 객체 장애에 효율적으로 대처하는 방법을 고찰한다. 객체 장애를 고려하여 안정성을 높이는 방법으로서 객체를 복제(replication)하는 방법이 가능하다. 본 논문에서는 이와 함께 Fault Tolerant CORBA(FT-CORBA) 의 장애 복구까지 시스템을 지속적으로 운영하기 위한 방법을 고찰함으로써 궁극적으로 시스템의 안정성을 향상하고 이에 따라 서비스의 연속성을 유지시킬 수 있는 방법을 제시한다.
