Oracle Database Performance Tuning Guide is an aid for people responsible for the
operation, maintenance, and performance of Oracle. This book describes detailed
ways to enhance Oracle performance by writing and tuning SQL properly, using
performance tools, and optimizing instance performance. It also explains how to
create an initial database for good performance and includes performance-related
reference information. This book could be useful for database administrators,
application designers, and programmers.
This book covers everything you need to know to pass the OCP: Oracle8i
Performance and Tuning and OCP: Oracle8i Network Administration
exams. The first part of the book covers the most critical areas of database
performance tuning and how to follow and implement Oracle’s recommended
tuning methodology. The second part covers the topics of network
administration including configuring the necessary client and server components
of an Oracle network and helps you develop an understanding of the
Oracle 8i Net8 architecture....
This book is about tuning Oracle databases. Three areas of Oracle Database tuning are data model tuning, SQL code tuning, and physical and configuration tuning. The author began his career as an applications developer, not as a systems or network administrator. As a result, this book is written from an applications rather than an operating system perspective.
AD HOC NETWORKS: Technologies and Protocols is a concise in-depth treatment of various constituent components of ad hoc network protocols. It reviews issues related to medium access control, scalable routing, group communications, use of directional/smart antennas, network security, and power management among other topics. The authors examine various technologies that may aid ad hoc networking including the presence of an ability to tune transmission power levels or the deployment of sophisticated smart antennae. ...

The grandest accomplishments of engineering took place in the twentieth century. The widespread development and distribution of electricity and clean water, automobiles and airplanes, radio and television, spacecraft and lasers, antibiotics and medical imaging, computers and the Internet are just some of the highlights from a century in which engineering revolutionized and improved virtually every aspect of human life. In this book, the authors provide a glimpse of the new trends of technologies pertaining to control, management, computational intelligence and network systems....
With the ever-increasing demand for higher performance in the optical
network, there is a need for higher performance in optical connectors.
Connector performance is typically defined as a measurement of insertion
loss that occurs when the connector is mated to a reference connector.
Manufacturers use reference connectors for production testing of insertion
loss because they provide a repeatable reference point.
In a two-tier network, a client communicates directly with a server. This is also known as a client-server architecture. A client-server network is an architecture that involves client processes that request services from server processes. The client and server communicate over a network using a given protocol, which must be installed on both the client and the server.
A common error in client-server network development is to prototype an application in a small, two-tier environment and then scale up by adding more users to the server.
Learning objectives of this chapter include: Describe how OSPF creates neighbor adjacencies in a multiaccess network, describe the method and command used to propagate a default route within the OSPF area for IPv4 and IPv6, examine the methods of fine-tuning OSPF for IPv4 and IPv6 on interfaces,...
Linux Server Hacks is a collection of 100 industrial-strength hacks, providing tips and tools that solve practical problems for Linux system administrators. Every hack can be read in just a few minutes but will save hours of searching for the right answer. Some of the hacks are subtle, many of them are non-obvious, and all of them demonstrate the power and flexibility of a Linux system. You'll find hacks devoted to tuning the Linux kernel to make your system run more efficiently, as well as using CVS or RCS to track the revision to system files....

Assume that gi (x) = 1 (hence gk (x) = 0, k = i), update the expert i based on output error. Update gating network so that gi (x) is even closer to unity. Alternatively, a batch training method can be adopted: 1. Apply a clustering algorithm to cluster the set of training samples into n clusters. Use the membership information to train the gating network. 2. Assign each cluster to an expert module and train the corresponding expert module. 3. Fine-tune the performance using gradient-based learning. Note that the function of the gating network is to partition the feature...

Every aspect of a network-storage, file transfers, backup-depends on the filesystem for structure, functionality, and integrity. Surprisingly, UNIX-the operating system of choice for mission-critical networks-has historically had little documentation on its filesystem structures. Written by Steve Pate, a sen-ior member of the VERITAS Filesystems Group, this book sheds light on the inner workings of UNIX filesystems and gives you the know-how to fine-tune your UNIX filesystems for optimal performance.
Oracle system performance inefficiencies often go undetected for months or even years--even under intense scrutiny--because traditional Oracle performance analysis methods and tools are fundamentally flawed. They're unreliable and inefficient.
Oracle DBAs and developers are all too familiar with the outlay of time and resources, blown budgets, missed deadlines, and marginally effective performance fiddling that is commonplace with traditional methods of Oracle performance tuning.
