Labs are generally at the end of the lecture and the instructor will be available for Q & A and lab assistance after the lecture. Lab solutions will always be reviewed. The course guide will be provided electronically and students can print a copy if they desire a hard copy. The course guide contains all the lecture slides and instructor notes, the labs, lab solutions, and relevant white papers. This course covers a number of advanced topics such as Index clustering factor, Oracle10g Tablespace options that affect index performance, various Oracle traces including the 10053 Cost-Based Optimizer trace and sizing the SORT_AREA_SIZE and HASH_AREA_SIZE using the 10053, 10033, 10034, and 10104 traces. Lectures include an in-depth look at various SGA structures such as buffer cache options and sizing, library cache and cursor sharing, and Oracle fragmentation and locking issues/data block internals. Students will also experience how to monitor their application environment, their indexes, and see how to find problem SQL in their applications using Stats Pack, SQL Trace, AWR, SQL Tuning Advisor, and the V$ dictionary tables (using a variety of supplied SQL*Plus scripts). This 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/not being used. Hands-on lab exercises that reinforce the lecture topics. This course shows how to use TOAD, SQL Developer and SQL*Plus for SQL Performance Tuning. Topics covered includes: • Oracle Architecture from a SQL Performance point-of-view • Review of Reading Explain Plans/Understanding Explain Plans • Review of CBO Hints • A close look at Indexes – how they work and how they are selected and advanced topics such as clustering factor and other reasons indexes may NOT be selected • Oracle Trace Facility/Stats Pack/Wait Events • Tracing wait events back to the problem SQL • Oracle AWR and new tools such as SQL T are covered • Profiling PL/SQL, PL/SQL Coding Tips • SGA topics include: o Buffer Cache options and sizing o Library Cache utilization/internals including cursor-sharing topics o Oracle11g Result Cache • Oracle10g Tablespace options that affect indexes • Oracle data block internals and fragmentation reviewed • Finding various problems using the V$ dictionary tables with scripts. This course is perfect for DBA’s that need the additional background to solve the more difficult problems. Workshop Prerequisites: A background in SQL tuning working knowledge of the SQL language. Knowledge of SQL Explain Plans is helpful and will be reviewed.

Lectures and topics are enhanced with live illustrations and hands-on exercises Attendees Receive: • Study guide with presentations and relevant white papers • Zip file full of tuning and problem discovery scripts • Opportunity to ask the tough Oracle questions • A hands-on opportunity to learn more about Oracle, SQL Developer, and TOAD
