Oracle Database Release 11.2.0.2 introduced several new features directly related to parallelization of SQL statements, including Auto Degree of Parallelism (ADOP) and In-Memory Parallel Execution (IMPE). Oracle DBA and Oracle University instructor Jim Czuprynski will demonstrate how to implement these latest parallelism features to provide maximum performance benefits - for DML as well as queries - within your Oracle 11gR2 database environments.
Through presentations and online demonstrations, this session will:
- Explore the new parallelism features, especially ADOP and IMPE, in Oracle Database 11.2.0.2
- Explain how to implement the appropriate initialization parameters, hints, and object decoration to influence parallelism for maximum effectiveness
- Demonstrate how to use the feature set of the DBMS_PARALLEL_EXECUTE package to apply these new parallelism features to DML statements
