Increasing the Resilience of Distributed and Replicated Database Systems
This paper presents a new atomic commitment protocol enhanced three phase commit E PC that always allows a quorum in the system to make progress Previously suggested quorum based protocols e g the quorum based three phase commit PC Ske allow a quorum to make progress in case of one failure If failures cascade however and the quorum in the system is lost i e at a given time no quorum component e...
متن کاملSite Recovery in Replicated Distributed Database Systems
A solution to the problem of integrating a recovering site inLo a distributed database system is presented. The basic idea used for the correct recovery is to maintain a consistent view of the status (up or down) of all sites. This view need not be the exact current status of the sites. but is the status as perceived by other sites. The session number is used to represent the actual state of a ...
متن کاملNon-replicated Dynamic Data Allocation in Distributed Database Systems
Allocation of data or fragments in distributed database is a critical design issue and requires the most effort. It has the greater impact on the quality of the final solution and hence the operational efficiency of the system. Performance of the distributed database system is heavily dependent on allocation of data among the different sites over the network. The static allocation provides only...
متن کاملIssues in Replicated data for Distributed Real-Time Database Systems
In both Distributed and Real Time Databases Systems replication are interesting areas for the new researchers. In this paper, we provide an overview to compare replication techniques available for these database systems. Data consistency and scalability are the issues that are considered in this paper. Those issues are maintaining consistency between the actual state of the real-time object of ...
متن کاملDistributed Overload Control for Real-Time Replicated Database Systems
In order to meet their temporal constraints, current applications such as Web-based services and electronic commerce use the technique of data replication. To take the replication benefit, we need to develop concurrency control mechanisms with high performance even when the distributed system is overloaded. In this paper, we present a protocol that uses a new notion called importance value whic...
