ORACLE TUNING DONALD K BURLESON PDF

This class is aimed at Oracle DBAs and Oracle developers, an opportunity to get an in-depth functional understanding into the performance tuning of complex Oracle database systems from a leading tuning expert. Topics include the full curriculum from our popular Oracle Performance tuning class. You will need to bring a laptop with Oracle installed if you wish to participate in the class exercises. Burleson Introduction This section introduces participants to a series of tuning steps that can be used to improve the performance of the Oracle Server. The focus is on database issues rather than specific operating system performance issues. Students will learn how to recognize, troubleshoot, and resolve common performance-related problems in administering an Oracle database.

This class is aimed at Oracle DBAs and Oracle developers, an opportunity to get an in-depth functional understanding into the performance tuning of complex Oracle database systems from a leading tuning expert. Topics include the full curriculum from our popular Oracle Performance tuning class.

You will need to bring a laptop with Oracle installed if you wish to participate in the class exercises. Burleson Introduction This section introduces participants to a series of tuning steps that can be used to improve the performance of the Oracle Server. The focus is on database issues rather than specific operating system performance issues. Students will learn how to recognize, troubleshoot, and resolve common performance-related problems in administering an Oracle database.

Students will learn how to identify and diagnose Oracle memory performance problems, including problems in the library cache, data buffer cache and data dictionary cache. Learning Objectives - After completing this course, students will be able to: Tune the Oracle shared pool Tune the data buffer cache Tune Oracle rollback segments Tune Oracle redo mechanisms Monitor and detect lock contention Identify Oracle sort operations This area will examine the behavior of the Oracle instance and look into the behavior of the Oracle background process and the SGA memory.

The topics for this section will include iterations of recommendations for changes to init. Oracle Instance Tuning This section will also explore how to measures changes to the SGA performance and how to document the performance improvements.

Redo Logs — This section to introduce the performance characteristics of the Oracle online and archived redo logs.

UNDO Rollback segments — This section explores the interaction between the Oracle rollback segments and the performance of the Oracle database. Shared pool issues — This section will discuss the management of the components of the shared pool with a focus on the management of activity in the library cache. Miscellaneous Initialization parameters — Other init.

The focus will be on the tradeoff between efficient space management and high performance of select and insert SQL statements Oracle index internals — This section will explain the relative benefits for b-tree, bitmapped and function-based indexing. This section will also explain how to analyze indexes to determine those indexes that require re-building. Oracle replication — This section will explore Oracle replication and explain the ramifications of replication versus database links for distributed data.

Oracle segment internals — This includes the high-water make and the effect on full-tale scans after deletes. This section also includes a section on the pctused parameter and the effect on space re-use and the performance of subsequent insert statements. There will also be a discussion of pctfree and how pctfree can be used to avoid row chaining.

Object access patterns — A technique will be introduced to explain all of the SQL in the library cache. This technique is indispensable for identify long-table full-table scans, identifying small tables for caching. Tuning Oracle Data access This section takes an in-depth look into the concepts and skills needed to tune Oracle with SQL Students will learn about the broader issues of tuning with SQL, and then delve into tuning with the Optimizers, the Explain Plan Utility, Hints, and other tuning techniques.

After completing this course, students will be able to tune all Oracle SQL and take the actions required to ensure optimal SQL performance. The focus on the SQL tuning will be to tune the most frequently executed statements first, and move down the list as time permits.

The areas for SQL tuning will be to optimize execution plans by removing unnecessary full-table scans, fully utilizing indexes, and implementing advanced hints to derive the optimal execution plan for each query. Cost-based vs. Rule-based optimization — See the relative benefits of cost-based vs rule based optimization and see when to use rule and cost hints.

Tuning with Parallel query - This section describes how parallel query works, and how to best provide parallelism for Oracle. Tuning the external environment This section will teach students about external influences on Oracle performance, how to measure them, and how to ensure that the external environment is properly configured for Oracle. Students will learn how to take advantage of all the UNIX-based tools for monitoring, configuring, and tuning the external environment.

The external environment will be monitored using the vmstat and iostat utilities. This section will discuss the iterations of recommendations relating to environmental tuning such as OS dispatching priorities, swap space allocation, and other OS-specific issues. This section will also includes an easy method for capturing environmental statistics inside Oracle tables for long-term analysis.

Oracle Expert Tuning Secrets - Part 1

This complexity requires that the DBA have expert knowledge of Oracle internals. This book provides a thorough step-by-step approach for holistic Oracle tuning in this challenging information technology era. It represents the knowledge accumulated from tuning thousands of Oracle databases. By understanding these time-series tables, we can develop time-series tuning models to predict upcoming outages and dynamically change the instance to accommodate the impending resource changes. Database tuning efforts must become as sophisticated as the databases themselves.

Oracle Tuning: The Definitive Reference by Donald K. Burleson

Oracle and Expert Systems Technology Oracle - Developing a Performance scope of work Whereas reactive tuning involves running a few Oracle scripts and interpreting the results, ongoing tuning involves tracking changes in performance metrics over time and making planned changes to correct the situation. The Oracle DBA has many choices for accomplishing this goal. They can buy third-party tools to collect Oracle performance data or they can write extensions onto the Oracle utilities that dump the performance data into Oracle tables for later analysis. In either case, we need to be conscious of the fact that tuning is an ongoing process. A new, empty database may perform far differently than after it has been loaded with data.
