2 Training Description: Introduction to Oracle Administration and Management is a five-day course designed to provide Oracle professionals with an in-depth understanding of the basic features of Oracle including object-orientation, partitioning and advanced Oracle features for the Internet. This course is an introductory course for Oracle DBA s. The goal of this course is to cover the Oracle architecture and internal mechanisms such that the student is able to perform basic DBA tasks such as database creation, startup and shutdown, and database management. The course also covers Oracle networking basics and the Oracle utility programs. In-class exercises are used to demonstrate each feature and the participants will gain first-hand experience in the key Oracle DBA concepts. Please note that this course is not taught as a preparatory course for the Oracle Certified Professional (OCP) program. Training Objective: By the end of the training, participants will be able to: Have a functional understanding of the roles and duties involved in Oracle database administration and be able to perform basic Oracle DBA tasks Training Designed for: This course is intended for computer professional who needs to understand the basic concepts and architecture of Oracle. This includes Oracle developers, Oracle DBAs, Oracle web developers and any computer professional who needs to understand the architecture of an Oracle database. The participants should understand basic relational database concepts such as SQL before enrolling in this training. Training Program: DAY ONE: PRE-TEST Introduction Architecture & Configuration Overview of Oracle DBA tasks o Oracle as a flexible, complex & robust RDBMS o The evolution of hardware and the relation to Oracle o Different DBA job roles (VP of DBA, developer DBA, production DBA, database babysitter) o The changing job role of the Oracle DBA o Environment management (network, CPU, disk and RAM) o Instance management (managing SGA regions) o Oracle table and index management IT100 Rev.001 CMCT COURSE OUTLINE Page 2 of 8
