Four Steps to Oracle SQL Tuning  - A Methodolgy
Learn a predictable and repeatable methodology for tuning Oracle SQL statements. Just four steps that you should always follow when tuning an SQL statement. (Note this video does not contain examples of how to apply the four steps, just what the steps are.) Oracle Certified Master John Watson presents. John concludes with a brief overview of how SkillBuilders SQL tuning course provides the information you need to apply the four steps. Learn more about SkillBuilders SQL Tuning course http://skillbuilders.com/oracle-sql-tuning-training 1. What is Oracle doing? (explain plan, trace) 2. Why is Oracle doing it that way? (analyze the execution plan) 3. Is there a better way? Test! 4. If there's a better way, push the CBO towards the better way.

Tracing: Transaction ST12 = Combination of two transactions . SAT (ABAP Trace) , ST05 = SQL Trace SQL Trace: To monitor the database access of reports and transactions. Less common traces : Enqueue Trace: (the locking system),RFC Trace, Table buffer trace: Performance Improvements ABAP Coding: Keep an eye on those loops. Select statements in loops = absolutely avoid = use for all entries instead Function call, or performs in loops = re - visit and see if you can optimize The "READ TABLE" statement Sorted table- Binary search .. Or even better use "Index" on internal tables. Use mass operations on internal table = internal table copy one to another, Append lines of int_fligh1 to int_fligh2. Use field symbols to modify internal table in a loop (minor improvement ) A little trick if you call performs in a loop:: Use static variables Avoid sleep, wait etc commands.. Or synchronous RFC calls 2)Database bottleneck Use Indexes : Make sure Indexes are being used in your select statement (check with trace if needed) Extreme case , create new index (this has the disadvantage of making the insert slower) Select -- End select loop : Usually database optimiser will fix it, still avoid it Select * into corresponding fields = about a millisecond slower Make clever use of inner joins Use views Use (max,min, avg): example : Select max( flightnum ) from flight . GET RUN TIME command Reduce I/O first, then memory, then CPU activity.Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory)

Oracle SQL Performance Tuning for Developers: Introduction
This video is an introduction to Oracle SQL Performance Tuning for Developers: http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027 6+ Hours of Video Instruction The focus of Oracle SQL Performance Tuning for Developers LiveLessons is to illustrate coding techniques that ensure a consistent response time between instances and releases of the Oracle database. This course works closely with performance tuning of actual SQL statements. Description In this video training, Dan Hotka starts out with a complete overview of the Oracle architecture so students can get an understanding how their SQL and applications can take advantage of the computing environment. This course then goes in-depth on understanding and controlling the Explain Plan, which is how and in what order Oracle retrieves data. The discussion includes considerable detail, with SQL examples, on how the optimizers--both rule-based and cost-based, but mostly cost-based--make their decisions. Students will work with a variety of SQL statements, reviewing Explain Plans and making changes to make these SQL statements perform better. Lectures include index design, using hints and coding style to control the Explain Plans, and how to use useful tools such as index monitoring, SQL Trace, and the PL/SQL profiler. This LiveLessons course takes a close look at indexes: how Oracle selects them, why they are sometimes not used, and how to tell if indexes are being used. This course includes Oracle10g, Oracle11g, and Oracle12c SQL tuning topics. Skill Level Intermediate Learn How To Read and understand Explain Plan content Review an Explain Plan and tell quickly if this is a good plan Understand a good index column candidate from a not-so-good candidate Quickly tell the likelihood if your SQL will use an existing index Use coding and a variety of Hints (directives) that can produce better performing SQL Execute and interpret SQL trace output Who Should Take This Course Oracle programmers Oracle database administrators who need additional training on SQL tuning Course Requirements Working knowledge of the SQL query language http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027

Webinar: Ten (Other) Top Tips for Improving PL/SQL Performance
Bulk processing (FORALL and BULK COLLECT), along with the function result cache, are the "big ticket" items when it comes to performance optimization with PL/SQL. But there's still more we can do to tweak our code for even better response times for our users. This third webast in the series starts with the automatic compiler optimization, showcases the extraordinary speediness of PGA data manipulation (a.k.a., package variables), and demonstrates the effect of the simple NOCOPY hint. We finish up with an introduction to pipelined table functions and some thoughts on optimizing your algorithms.

Oracle SQL Tuning - How to Read Execution Plans (Explain Plan)
In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).
