Course Overview
After completing this seminar, you'll understand the benefits of parallelizing requests in an Oracle 12c database. You'll also be able to use features of parallel processing introduced in Oracle 11g Release 1 and 2.
Learn To:
- Optimize SQL statement execution using parallel processing.
- Use parallel processing appropriately to derive a benefit over serial processing.
- Control the use of parallel processing.
- Use a variety of features for parallelizing statements.
- Read execution plans of parallelized statements.
- Troubleshoot different issues associated with parallel processing.
- Use, control and manage parallelization.
Benefits To You
Through focused lessons and hands-on demonstrations, expert Oracle University instructors will teach you when and why parallel processing is relevant and effective. You'll also explore specific configurations like RAC database and Database Machine.
