TRAINING COURSE OVERVIEW

Our Oracle SQL Performance and tuning training course is there to ensure that performance is considered when designing, coding and then later maintaining Oracle applications in production. JBI offers courses for SQL developers,  support staff and DBAs that understand Oracle Performance issues and attempts to meet them head on. As well as introducing the obvious tools, we also show the good and bad side to SQL hints and give many SQL coding tips and techniques that are proved through plan analysis.


AUDIENCE

This in-depth class is intended for technical users of the Oracle database system who are responsible for ensuring peak performance in an intensive production environment.

  • We Introduce the SQL optimizer main features, its options and opprtunities in plain and simple language.
  • We spends introduce, explain and plan tables in their many forms, and how to interpret them.
  • We go through common SQL access paths for common coding approaches including major areas such as  selectivity principles, and optimizer approaches to joins, subqueries, set approaches and managing sorts .
  • We introduce powerful and efficient SQL techniques and options such as inline views, use of analytic functions, merge, and rollup and cube
  • We also show the good and bad side to SQL hints and give many SQL coding tips and techniques that are proved through plan analysis.
  • We provide straight forward access and explanations to the AWR “world”  (including AWR and ASH reports, plus ADDM).
  • And finally we show how to build SQL Tuning sets and then use them with  SQL Performance Analyser, SQL Tuning and Access advisors.
  • Often, delegates are quite literally astonished at the new information sources they  now have access to, that can help them do a difficult job more effectively.
