Oracle Partitioning and Parallel Execution for PerformanceTanel will be in 2010 in
* Brussel (BE) - 9 April 2010 (Click here to register)
* London (UK) - 4 June 2010 (Click here to register)
* Utrecht (NL) - 10 June 2010 (Click here to register) Seminar overviewOracle Database’s partitioning options can be used for help in three areas: VLDB information lifecycle manageability, data availability and performance. This seminar will mostly cover partitioning for performance, how to design partitioning for performance and how to write/troubleshoot SQL which should use partitioning for performance.
The second part of this section will cover parallel execution internals, tuning and troubleshooting, both in partitioned and non-partitioned environments and we also touch the topic of configuring parallel execution right on RAC.
Seminar Duration and Details
Seminar duration: 1 day
Audience: Senior DBAs, senior developers, database designers
Skill level: Intermediate to Advanced
You will learn the following…
· Best practices for partitioning (in different circumstances) and how to avoid common pitfalls
· How to control partition pruning and measure whether desired partition pruning is happening
· How to achieve serial partition wise joins for joining large datasets
· Understand how the parallel execution engine and row distribution works
· Best practices for parallelism (in different circumstances) and how to avoid common pitfalls
· How to troubleshoot Parallel execution plans and see exactly where the bottleneck is
