Abstract :
Crash and media recovery problems that have to be addressed in data sharing systems are addressed. Recovery is complicated by dependencies on other functions such as buffer management and concurrency control. Furthermore, a global log file is to be constructed where the modifications of committed transactions are reflected in chronological order. Logging and recovery protocols that employ the primary copy approach for concurrency/coherence control are proposed for loosely coupled data sharing systems. A comparison with existing data sharing system shows that the protocols support high performance during normal processing as well as efficient recovery that provides high availability.<>
