THE new z/OS 1.2 TCP/IP stack introduces a greatly enhanced Simple Network Management Protocol (SNMP) Management Information Base (MIB) to allow the systems programmer to perform diagnostics for the TCP/IP stack and sessions. The SNMP MIB includes hundreds of variables to analyze the core Internet protocols: Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UD...

the VAXcluster system to VMS version 5.4-3 increases tolerate and work around the availability of local network failures. area VAXcluster (LAVc) This paper describes the configurations by allowing availability features added the use of multiple local to local area VAXcluster area network (LAN) adapters (LAVc) support in VMS in the VAXcluster system. version 5.4-3. These Availability is increase...

This article presents a computational model of the learning of diagnostic knowledge based on observations of human operators engaged in a real-world troubleshooting task. We present a model of problem solving and learning in which the reasoner introspects about its own performance on the problem solving task, identifies what it needs to learn to improve its performance, formulates learning goal...

We develop and extend existing decision-theoretic methods for troubleshooting a nonfunctioning device. Traditionally, diagnosis with Bayesian networks has focused on belief updating| determining the probabilities of various faults given current observations. In this paper, we extend this paradigm to include taking actions. In particular, we consider three classes of actions: (1) we can make obs...

The complexity of home networks has evolved to a greater level of sophistication and complicacy in the recent times comprising of heterogeneous components like at least two computers, webenabled high-definition television sets, net-enabled blue ray disc players, iPods and many other such devices. Troubleshooting such a sophisticated smart home network in case of a malfunction by the novice end ...

Contextual Graphs are a context-based formalism used in various real-world applications. They allow a uniform representation of elements of reasoning and of contexts for describing different human tasks such as troubleshooting and interpretation. A contextual graph represents a task realization. Its paths represent the different ways of reaching this realization, each way corresponding to a pra...

This paper presents a computational model of integrated introspective learning, which is a deliberative learning process in which a rea-soner introspects about its own performance on a reasoning task, identiies what it needs to learn to improve its performance, formulates learning goals to acquire the required knowledge, and pursues its learning goals using multiple learning strategies. We disc...

Humans and machines fail. It is a matter of fact. Preventing, recognizing, and troubleshooting problems with the many intricate systems used by perfusionists are key skills within the profession. Preventive measures are used in an attempt to fend off errors before they occur. Skills are taught during the educational process to enable clinicians to recover from, and mitigate the effects of, crit...

We developed BRITE (Bringing Resources and Information to Employees), an expert information retrieval system, for problem solving and retrieving technical product information. Specialists in our Technical Assistance Center (TAC) use the BRITE system on a Pentium workstation to access information in < 3 s. Manuals, technical bulletins, parts lists, and administrative tools such as word processin...
