Fault Detection and Fault Tolerance in a Loosely Integrated Heterogeneous Database System

نویسنده

  • Wanlei Zhou
چکیده

This paper presents the design and prototype implementation of a reactive system that facilitates the fault detection and fault tolerance for a loosely integrated heterogeneous database system. The fault detection mechanism uses sensors to monitor individual databases and system objects and to detect database or system component failures. The fault tolerance mechanism uses actuators to react on these failures.

Detecting and tolerating failures in a loosely integrated heterogeneous database system

This paper presents the design and prototype implementation of a fault detection and fault tolerance facility based on the reactive system model for a loosely integrated heterogeneous database system running on a network of workstations. The database system consists of a number of fully autonomous databases that, through their willingness, can share some portion of their information. Sensors (f...

Using Sensors to Detect Failures in a Loosely Integrated Heterogeneous Database System

In this paper we apply the reactive system concepts in the design and implementation of a fault detection facility for a loosely integrated heterogeneous database system. The database system consists of a number of fully autonomous databases that, through their willingness, can share some portion of their information. Sensors (functions that expose some part of the state of an object) are place...

An approach to fault detection and correction in design of systems using of Turbo ‎codes‎

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

Integrated Fault-detection and Control of DC Microgrids Using SDRE Observer-controller

In this paper, using the state-dependent Riccati equation (SDRE) technique, a suboptimal fault-tolerant control scheme is designed for a DC microgrid in the islanded mode. The objectives are the voltages control of the photo-voltaic cell, the battery, the capacitor bank, and the DC bus as well as on time fault detection. In the design procedure of the SDRE observer-controller, a nonlinear mathe...
