Training Course Objectives:
Everyone involved with the Oracle system; system architects, designers, developers and database administrators (DBA's), should consider performance tuning while carrying out their work.
This course is aimed at the DBA's who often have to make the first attempt at solving performance problems prior to, and as they develop. We cover all aspects of internal database tuning on an Oracle 10g platform in this three-day course.
The enhancements and changes that have been introduced in 10g will be discussed during this course for the benefit of DBA's responsible for earlier RDBMS versions for the purposes of planning and upgrade tuning.
