Course Information

Course Description

​The purpose of this Oracle Database 10g training course is to equip database administrators to recognize, diagnose and remedy performance problems which might arise in the operation of the Oracle database server. Beyond reactive measures, proactive actions which can be taken to avoid performance issues before they arise or are recognized are also considered.

Course Objectives

​The objective of this Oracle Database Administration training course is to consider present a comprehensive consideration of data warehouse features that exist within the Oracle database.

Major subject areas to be explored are:
• Utilization of advanced self-tuning and self-management capabilities, including the use of the database Advisors and other components of the Management Framework.
• Performance monitoring, problem troubleshooting, and resolution.
• Detailed scrutiny of database activity using statistics and wait events.
• Manual tuning using Statspack.
• Tuning of the shared pool, buffer cache and shared memory
• Tuning recovery structures such as checkpoints and redo data
• Tuning physical storage structures such as file I/O and database blocks
• Tuning specialty structures such as the PGA and temporary space

Course Audience

​Target audience for this Oracle Database training course is database administrators, data warehouse administrators and application developers who will be responsible for implementing and using data warehouse technology.
