Handling difficult faults in operating systems

R. M. Needham
1971 Proceedings of the third symposium on Operating systems principles - SOSP '71  
It is commonplace to build facilities into operating systems to handle faults which occur in user-level programs.  ...  These facilities are often inadequate for their task; some faults or incidents are regarded as so bad that the user cannot be allowed to act on them and this makes it difficult or impossible to write subsystems  ...  This desire for 'complete encapsulation' is quite different from what is done in systems where the handling of faults is dealt with in a unified scheme of levels through which faults ore passed back in  ...

A sentinel approach to fault handling in multi-agent systems [chapter]

Staffan Hägg
1997 Lecture Notes in Computer Science  
Fault handling in Multi-Agent Systems (MAS) is not much addressed in current research.  ...  Normally, it is considered difficult to address in detail and often well covered by traditional methods, relying on the underlying communication and operating system.  ...  Introduction Fault handling in Multi-Agent Systems When discussing fault handling in multi-agent systems (MAS) there are often two opposite positions.  ...

Waves of Faults in Embedded System and Way out through Fault Tolerance

Jigna B. Prajapati, Author Dr.N.K.Modi, Savan K.Patel
2011 International Journal of Computer Applications  
Faults are subdivided into different activities such as fault prediction, fault detection, fault prevention, fault correction etc. Here we study the faults in context boiler system.  ...  In initially, the paper focus on the different types of faults, their impact and fault classification.  ...  Any wrong data will feed up (user faults) in system will handle by exceptional handling. If more resources are required and any faults occurred due to such reasons then we can apply Processor pair.  ...

Hector: Detecting Resource-Release Omission Faults in error-handling code for systems software

Suman Saha, Jean-Pierre Lozi, Gael Thomas, Julia L. Lawall, Gilles Muller
2013 2013 43rd Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN)  
Omitting resource-release operations in systems error handling code can lead to memory leaks, crashes, and deadlocks.  ...  We propose a novel microscopic approach to finding resourcerelease omission faults in systems software.  ...  Estimating the rate of false negatives is difficult, because it requires complete knowledge of the set of faults in a system.  ...

Fault Tolerant System for Embedded System Architecture

Namita Arya, Amit Prakash Singh
2017 International Journal of Engineering and Technology  
In the reference, we operate re-execution concept in operations to avoid or tolerate temporary fault like transient faults in software and this is called time redundancy concept.  ...  There is an efficient interpose between crystallization in hardware and system reimplementation in software to have a maximum fault tolerance system with lowest possible cost possible.  ...  The system operations are proportionally equal to the number of tolerated transient faults.  ...

2018 MATEC Web of Conferences  
The fault handling information matrix is established to record the dispatcher fault handling operation sequence and operation information.  ...  The four situations of the dispatcher fault isolation operation are analyzed. The fault handling anti-misoperation rule set is established to describe the rules prohibiting dispatcher operation.  ...  The fault handling information matrix (FHIM) is set up to describe the operation sequence and operation information of the equipment in the process of the dispatcher's fault treatment.  ...

Review of Software Fault-Tolerance Methods for Reliability Enhancement of Real-Time Software Systems

Anjushi Verma, Ankur Ghartaan, Tirthankar Gayen
2016 International Journal of Electrical and Computer Engineering (IJECE)  
Although, there are several researches concerned with achieving fault tolerance in the presence of various functional and operational errors but many of them did not address the problem concerned with  ...  the timing bugs which is an important issue in real time systems.  ...  In order to achieve failure free operation of software, one develops some mechanism to handle those faults which remain in the system even after its development.  ...

Error Handling: From Theory to Practice [chapter]

Ivan Lanese, Fabrizio Montesi
2010 Lecture Notes in Computer Science  
We describe the different issues that a language designer has to tackle when defining error handling mechanisms for service-oriented computing.  ...  We first discuss the issues that have to be considered when developing error handling mechanisms inside a process calculus, i.e. an abstract model.  ...  Type errors are managed in different ways according to where they happen. In one-way operations, a type mismatch of an outgoing message generates locally a system fault TypeMismatch.  ...
