Oracle Database 11g: Performance Tuning
|
1. Thời lượng: 40 hours
2. Mục tiêu khóa học
Get the most out of your 11g Database by learning performance tuning methods that maximize the utility of the database. Students learn how to benefit from Oracle Database 11g automatic tuning features, as well as practicing the manual tuning methods using the statspack tool. After clearly defining the various methodologies one can use to tune an Oracle Database, the course covers the various tunable components of an Oracle Database. Throughout the course, students experience hands-on the tuning of an Oracle Database by practicing through a series of workshops.
