Oracle Insights: Tales of the Oak Table

Oracle Insights: Tales of the Oak table eleven world-renowned industry experts proffering their own point of view very experienced, entry, and insights on Oracle where he was, wherever he goes, how (and how not) to use successfully, the software and techniques they have put in place to help people achieve their objectives, and some frightening tales of what can happen when the fundamental design principles are ignored.

The co-authors have solved many problems of the worst performance of Oracle in the world, and they have saved at least one each sentenced flagship project. For many years, they have been sharing their unique knowledge with each other at conferences around the OakTable, and in cafes, restaurants and bars on five continents. Now they want to share their key ideas with you.

A central feature of this book focuses on how you can avoid mistakes and debilitating during the construction of Oracle software projects. From these stories, you discover the simple steps to help you avoid real pain on your next (or current) Oracle project.

Since 1992, Oracle introduced a new way of extracting detailed information on response time of a database: SQL extended the mechanism trace. In 1995, I began to learn much more about this feature when my colleagues at Oracle Corporation, used to eliminate the guesswork Oracle performance improvement projects. The magic of this new extended SQL trace feature is that it has led analysts to predict the exact response time impact of a change in the proposed system. At the time, this predictive capability was revolutionary. The predictability and the concept of "fully informed decision" was the basis of my career since then.

In 1999, I left the company Oracle to work full time creating a new method for improving the performance I was hoping that exceed by far the reliability and accuracy of traditional methods of Oracle. In our book, Oracle Performance Optimization (Millsap and Holt, O'Reilly & Associates, 2003), Jeff Holt and myself have published the full technical details of our new method and extent SQL trace tool itself. Here, I describe the story behind Oracle SQL extended capacity to trace its history, the people who contributed to the development, and how and why you might consider using it.

Pro Oracle Spatial

With growing reliance on spatial components for making critical and strategic decisions, there is great incentive to maximize the added value of spatial data. Enter: Pro Oracle Spatial. This highly anticipated book examines the potential for organizations to exploit spatial information by way of Oracle Spatial.

Included are case studies of advanced spatial applications in healthcare, telecom, retail, and distribution industries. Further, the content is based on extensive feedback from training courses, discussion lists, and customers. This talented author team will also suggest best-practice approaches to common problems.

The Advanced Spatial Engine has several subcomponents that cater to the complex analysis and manipulation of spatial data that is required in traditional GIS applications. Internally, each of these additional components uses the underlying geometry data type and index and geometry engine functionality.

The Network Data Model provides a data model for storing networks inside the Oracle database. Network elements (links and nodes) can be associated with costs and limits, for example, to model speed limits for road segments. Other functionality includes computation of the shortest path between two locations given a network of road segments, finding the N nearest nodes, and so on. The network data model is useful in routing applications. Typical routing applications include web services such as MapQuest and Yahoo! Maps, or navigation applications for roaming users using GPS technology. We cover more details about this component in Chapter 10.

The Linear Referencing System (LRS) facilitates the translation of mile-markers on a highway (or any other linear feature) to geographic coordinate space and vice versa. This component allows users to address different segments of a linear geometry, such as a highway, without actually referring to the coordinates of the segment. This functionality is useful in transportation and utility applications, such as gas pipeline management.

The Spatial Analysis and Mining Engine provides basic functionality for combining demographic and spatial analysis. This functionality is useful in identifying prospective sites for starting new stores based on customer density and income. These tools can also be used to materialize the influence of the neighborhood, which in turn can be used in improving the efficacy and predictive power of the Oracle Data Mining Engine.

GeoRaster facilitates the storage and retrieval of georeferenced images using their spatial footprints and the associated metadata. GeoRaster defines a new data type for storing raster images of geographically referenced objects. This functionality is useful in the management of satellite imagery.

The Topology Data Model supports detailed analysis and manipulation of spatial geometry data using finer topological elements such as nodes and edges. In some land-management applications, geometries share boundaries, as in the case of a property boundary and the road on which the property is situated. Oracle Spatial defines a new data type to represent topological elements (such as the shared “road segment”) that can be shared between different spatial objects. Updates to shared elements implicitly define updates to the sharing geometry objects. In general, this component allows for the editing and manipulation of nodes and edges without disturbing the topological semantics of the application.

PeopleSoft for the Oracle DBA

The newest addition to the series OakTable press, PeopleSoft to Oracle DBA, you teach a variety of techniques to maintain a system PeopleSoft. You will then be able to implement techniques such as indexing, the implementation DDL, managing tablespaces, and fixing low-performing SQL. Author, Kurtz, is an expert and, therefore, provides answers to questions that arise when using PeopleSoft on an Oracle database.

Kurtz's book begins with an architecture overview, then proceeded to BEA Tuxedo, PeopleSoft server applications. Kurtz smooth transitions between chapters that follow, explaining the structures database, connectivity, keys and indexing, PeopleSoft DDL, and tables. Kurtz gives appropriate weight to subjects as well as diagrams, performance measures, monitoring the performance of public services and optimization techniques SQL. And the final chapters provide valuable clues, advanced information on Tuxedo.

PeopleSoft is packaged business application software for large enterprises. This chapter provides an introduction and overview of PeopleSoft, its technology and history. We will take a very high level to discuss some of the major parties that make up today PeopleSoft systems, namely the database (in this case Oracle) that stores application data PeopleSoft and a large part of application code, Tuxedo Application Server, and PeopleTools the integrated development environment, which is used for most aspects of development and administration of PeopleSoft.

We will then pass the overall architecture of a PeopleSoft system and see how it has evolved in the first client / server architecture to the modern world four-tier Internet architecture. Finally, we'll take a look at what all this means for the database administrator (DBA) to maintain a PeopleSoft application, and we will consider the implications it has on relations between developers and database administrators on PeopleSoft. This introduction will bring some of the chapters in their context.

Expert Oracle JDBC Programming

JDBC is the most commonly used in the Java API to access and manipulate data in a database. Oracle is one of the most popular and scalable databases in the world. This book is a must for any developer to build an application that uses JDBC on the Oracle database. Unlike other books JDBC, this book was written to complement not rehash the contents of Oracle JDBC documentation and specifications JDBC.

The book teaches you not only how to write code JDBC, but how to write effective code JDBC in a step-by-step fashion. This book does not assume any prior knowledge of JDBC unless it requires a basic knowledge of SQL and PL / SQL. It covers JDBC with a focus on writing high performance, scalable and secure applications for Oracle 9i and 10g. The use of this book, you learn, among other things:

How effectively request, INSERT, UPDATE and DELETE data using JDBC

How to exploit the knowledge of Oracle fundamental in creating applications

What levels of transaction isolation, which supports those of Oracle and how to write your transactions effectively on Oracle

How to use proxy authentication to make your programs more secure

How to use Oracle objects and collections effectively in your applications

How to deal with the phenomenon of "loss of updates" using alternative optimistic and pessimistic locking strageties

How to exploit statement caching and connection pool to increase performance and scalability of your application

Expert Oracle Database 10g Administration

It is a single volume guide to the administration and management of the Oracle database. Completely revised and updated his best-seller 9i predecessor, this edition covers all new features, fully tested on the ground examples-and not only showcase examples.

This book touches on the new 10g management and performance tools and provides primers on Unix, Linux and Windows NT and administration based on SQL and PL / SQL programming techniques. And it offers anything new and aspring Oracle DBA must build and admisiter complex databases Oracle 10g.

In the first three chapters, I have prepared the ground to work with Oracle. It is time now to learn more about the fundamental structures of Oracle database 10g. Oracle uses a set of structures called logic blocks of data, measurements, segments and tablespaces that its constituent elements. Oracle physical database structure includes data files and related files. Oracle memory structures and a set of processes are the Oracle database example, and are actually responsible for all the work for you in the database.

To understand how the Oracle database work, you must understand several concepts, including transaction processing, backup and recovery, undo and redo data, optimizing SQL, and the importance of data dictionary . Oracle key features include the recovery manager, SQL * Plus and ISQL * Plus, Oracle Backup, Oracle (employment) Scheduler functionality, database Resource Manager, and Oracle Enterprise Manager management tool. This chapter gives an overview of the importance Oracle automatic management functions, and the sophistication built-in performance tuning features, including new automatic deposit of the workload, the database diagnostic automatic Monitor, and Councillor-based management framework.

Before you delve deeply into the logic and physical structures that constitute an Oracle database, however, we must be clear on a fundamental concept of the difference between an example Oracle and an Oracle database. It is very common for people to use the terms interchangeably, but they refer to different things altogether.

An Oracle database consists of files, both the Oracle data files and system files. These files by themselves are useless unless you can not interact with them in some way, which requires using the operating system, which provides processing capabilities and resources, such as memory, for you allow to manipulate the data on hard drives. When you combine all processes created by Oracle on the server with the memory allocated to it by the operating system, you get the example Oracle.

You'll often hear people pointing out that the database is in place, although what they mean is that the forum is increasing. "The database itself in the form a set of physical files is composed of, is of no use if the department is not up and running. The department carries out all work necessary for the database.

Expert Oracle Database Architecture: 9i and 10g Programming Techniques and Solutions

This is a defining book on the Oracle database for any developer or DBA who works with Oracle-driven database applications. Tom has a simple philosophy: you can treat Oracle as a black box and just stick data into it or you can understand how it works and exploit it as a powerful computing environment.

If you choose the latter, then you will find that there are few information management problems that you cannot solve quickly and elegantly.

Expert Oracle Database Architecture is the first of a three-book series that completely explores and defines the Oracle database. It covers all of the most important Oracle architecture features, including:

Files, memory structures and processes
Locking and latching
Transactions, concurrency and multi-versioning
Tables and Indexes
Partitioning and parallelism

Each feature is taught in a proof-by-example manner, not only discussing what it is, but also how it works, how to implement software using it, and the common pitfalls associated with it.

In summary, this book provides a one-stop resource containing deep wisdom on the design, development and administration of Oracle applications, written by one of the world’s foremost Oracle experts, Thomas Kyte.

Oracle is designed to be a very portable database; it is available on every platform of relevance, from Windows to UNIX to mainframes. For this reason, the physical architecture of Oracle looks different on different operating systems. For example, on a UNIX operating system, you will see Oracle implemented as many different operating system processes, with virtually a process per major function.

On UNIX, this is the correct implementation, as it works on a multiprocess foundation. On Windows, however, this architecture would be inappropriate and would not work very well (it would be slow and nonscaleable).

On the Windows platform, Oracle is implemented as a single, threaded process.

On IBM mainframe systems, running OS/390 and z/OS, the Oracle operating system-specific architecture exploits multiple OS/390 address spaces, all operating as a single Oracle instance. Up to 255 address spaces can be configured for a single database instance.

Moreover, Oracle works together with OS/390 Workload Manager (WLM) to establish execution priority of specific Oracle workloads relative to each other and relative to all other work in the OS/390 system. Even though the physical mechanisms used to implement Oracle from platform to platform vary, the architecture is sufficiently generalized so that you can get a good understanding of how Oracle works on all platforms.

In this chapter, I present a broad picture of this architecture. We’ll examine the Oracle server and define some terms such as “database” and “instance” (terms that always seem to cause confusion). We’ll take a look at what happens when we “connect” to Oracle and, at a high level, how the server manages memory. In the subsequent three chapters, we’ll look in detail at the three major components of the Oracle architecture:

Chapter 3 covers files. In this chapter, we’ll look at the set of five general categories of files that make up the database: parameter, data, temp, control, and redo log files. We’ll also cover other types of files, including trace, alert, dump (DMP), data pump, and simple flat files. We’ll look at the Oracle 10g new file area called the Flashback Recovery Area, and we’ll also discuss the impact that Automatic Storage Management (ASM) has on our file storage.

Chapter 4 covers the Oracle memory structures referred to as the System Global Area (SGA), Process Global Area (PGA), and User Global Area (UGA). We’ll examine the relationships between these structures, and we’ll also discuss the shared pool, large pool, Java pool, and various other SGA components.

Chapter 5 covers Oracle’s physical processes or threads. We’ll look at the three different types of processes that will be running on the database: server processes, background processes, and slave processes.

It was hard to decide which of these components to cover first. The processes use the SGA, so discussing the SGA before the processes might not make sense. On the other hand, when discussing the processes and what they do, I’ll need to make references to the SGA. These two components are closely tied: the files are acted on by the processes and would not make sense without first understanding what the processes do.

What I will do, then, in this chapter is define some terms and give a general overview of what Oracle looks like (if you were to draw it on a whiteboard). You’ll then be ready to delve into some of the details.
