This course also covers new features in Oracle10g /11g that will have an affect on your migrated applications. The focus of this tuning course is to cover advanced SQL performance tuning topics for those Oracle professionals that already have a SQL tuning background. This course is perfect for DBA’s that need the additional background to solve the more difficult problems

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 (and scripts to run them). 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
