Reviewing Amnesia Support in Database Recovery Protocols
نویسندگان
چکیده
Replication is used for providing highly available and fault-tolerant information systems, which are constructed on top of replication and recovery protocols. An important aspect when designing these systems is the failure model assumed. Replicated databases literature last trends consist in adopting the crashrecovery with partial amnesia failure model because in most cases it shortens the recovery times. But, despite the large use of such failure model we consider that most of these works do not handle accurately the amnesia phenomenon. Therefore, in this paper we survey some works, analyzing their amnesia support.

Improving Recovery in Weak-Voting Data Replication
Nowadays eager update everywhere replication protocols are widely proposed for replicated databases. They work together with recovery protocols in order to provide highly available and fault-tolerant information systems. This paper proposes two enhancements for reducing the recovery times, minimizing the recovery information to transfer. The idea is to consider on one hand a more realistic fail...
متن کاملOn Optimizing Certification-Based Database Recovery Supporting Amnesia
Certification-based database replication protocols are a good basis to develop replica recovery when they provide the snapshot isolation level. For such isolation level, no readset needs to be transferred between replicas nor checked in the certification phase. Additionally, these protocols need to maintain a historic list of writesets that is used for certifying the transactions that arrive to...
متن کاملComparison of fentanyl/midazolam with ketamine/midazolam for pediatric orthopedic emergencies.
OBJECTIVE Emergency management of pediatric fractures and dislocations requires effective analgesia, yet children's pain is often undertreated. We compared the safety and efficacy of fentanyl- versus ketamine- based protocols. METHODOLOGY Patients 5 to 15 years of age needing emergency fracture or joint reduction (FR) were randomized to receive intravenous midazolam plus either fentanyl (F/M)...
متن کاملXML-Based Semantic Database Definition Language
This paper analyzes different options for semantic database schema definition and describes a presentation format XSDL. Presentation of semantic database in a certain format implies that the format fully preserves the database content. If the database is exported to this format and then imported back to the database engine, the resulting database should be equivalent (Rishe, 1992) to the one th...

This paper examines the issue of what the self is by reviewing neuropsychological research, which converges on the idea that the self may be more complex and differentiated than previous treatments of the topic have suggested. Although some aspects of self-knowledge such as episodic recollection may be compromised in individuals, other aspects—for instance, semantic trait summaries—appear large...
