Abstract
Monitoring system and database performance is a complex task, and there can be many aspects to managing performance, including memory, disk, CPU, database objects, and database user sessions— just for starters. This chapter zeroes in on using Oracle’s Automatic Workload Repository (AWR) to gather data about the activities occurring within your database, and help convert that raw data into useful information to help gauge performance within your database for a specific period of time. Usually, when there are performance issues occurring within a database, it’s easy to know when the performance problems are occurring because database activity is “slow” during that given time frame. Knowing this time frame is the starting point to perform the analysis using the AWR information.
