Oracle Database 19c DBA Performance Tuning & Management Course Overview This Oracle Database 19c DBA Performance Tuning & Management course introduces the DBA to the main concepts of Oracle Database performance tuning and management. DBAs will gain practical experience in analyzing and tuning database performance. Delegates on the Oracle Database 19c DBA Performance Tuning & Management course will learn how to use tuning goals and methodologies to identify tuning contentions in an Oracle database and how to take corrective action,how to detect and tune common database performance problems,how to use the database advisors to proactively tune a database and how to use the various tools provided by Oracle to tune a database. Similarly,the course is targeted to closely follow the official Oracle Database curriculum for certification. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered. Versions supported 12cR2,18c,19c.
TARGET AUDIENCE:
Who will the Course Benefit? The Oracle Database 19c DBA Performance Tuning & Management course is suitable for database administrators and technical support staff who are required to monitor and tune an Oracle Database.
COURSE PREREQUISITES:
Requirements Delegates who wish to attend the Oracle Database 19c DBA Performance Tuning & Management course should have practical knowledge of using SQL and administering an Oracle database. They should have attended the Oracle SQL and the Oracle Database 19c Administration courses or have a good working knowledge of Oracle SQL and Oracle database administration. The ability to describe and use Oracle built-in packages would be highly advantageous but is not essential. This course is run on a Linux operating system,a basic knowledge of Linux/UNIX is recommended but is not essential. Where Oracle 19c courses are listed in pre-requisites or follow-on courses the equivalent Oracle 18c or Oracle 12cR2 courses would also suffice.
