Syllabus
 

Accurately Measuring Performance

What’s the right way to really measure the overall performance of a database and how is this accomplished when you have a large database farm to manage?  This chapter answers these questions and highlights the critical areas a DBA needs to stay focused on at all times. 

  • Modeling Peak Efficiency
  • Gauging Availability with v$ views
  • Gauging Transaction Speed with v$sqlarea
  • Availability Impact
  • Speed Impact

Correcting Foundational Flaws

Although some may disagree, most database gurus feel that laying the proper physical foundation for your database is the way to get the most performance bang for the buck. This chapter discusses the importance of proper physical design and helps DBAs diagnose physical design performance issues.

  • The Impact of Solid Database Design with v$bh analysis
  • The Number One Contributor to Database Performance
  • The Link Between Design and Performance Tuning with materialized views
  • Boosting Database Performance Through Design
  • How to Pinpoint Database Design Errors with v$sql analysis


 
Chapter 3: Optimizing Storage

Storage-related headaches are often the single biggest contributor to database downtime.  This chapter discusses the best ways to avoid storage problems through proactive planning and also provides fast diagnostic procedures that can be used to eliminate space problems before they reach critical mass.

  • The Contribution of Storage to Performance with RAID
  • Storage Design Considerations
  • Smart Ways to Avoid Database Downtime
  • Critical Storage Headaches to Avoid
  • Removing Storage-related Performance Vampires

Maximizing Oracle SGA Memory

Throwing more memory at a database used to be an acceptable form of performance tuning, but such is not the case any longer.  This chapter shows how to use memory correctly and also provides techniques and scripts to troubleshoot memory-related performance problems the right way.    

  • When Does Less Become More?
  • New Performance-Boosting Memory Options
  • How to Keep Data Where You Want It
  • How to Keep Code Where You Want It
  • Uncovering Memory Hogs

Pinpointing I/O Hotspots

How can a DBA quickly find the I/O bottlenecks in their database and then make them permanently go away?  This chapter outlines a bulletproof roadmap that any DBA can use to get a handle on their database I/O.  

  • Starting with Global Basics
  • Determining Global Object Access Patterns
  • Examining Storage-Level Statistics
  • Uncovering the Hot Database Objects
  • Locating I/O Resource Hogs
  • Miscellaneous I/O Considerations

Eliminating Critical Bottlenecks

A DBA needs to keep their database running effectively at all times, but sometimes this is easier said than done.  This chapter shows how to quickly find and eliminate critical bottlenecks in a database that may be causing painful slowdowns.

  • Using Ratio-based Methods
  • Using Wait-Event Methods
  • Other Bottleneck Identification Techniques
  • The Winning Solution


Uncovering Problem Sessions

Left unchecked, a few rogue users in a database can make life miserable for everyone else.  This chapter provides all the right ammunition a DBA needs to ferret out these problem sessions so that their database is kept secure and running well at all times. 

  • Uncovering Security Holes
  • Finding Storage Hogs
  • Locating Top Resource Sessions
  • Pinpointing Sessions with Problem SQL

Identifying Problem SQL

If it’s true that eighty-percent of a database’s performance is derived from the SQL code running within it, then a DBA has to know how to find and correct the problem SQL in their critical databases.  This chapter provides everything a DBA needs to quickly pinpoint the SQL code in their database that needs critical attention.  

  • Locating the Top SQL Contributors
  • Pinpointing Bad SQL
  • New Techniques for Analyzing SQL Execution
  • SQL Tuning Roadmap
