62 | Chapter 3: Installing and Running Oracle
The Automatic Workload Repository (AWR), first available in Oracle Database 10g,
maintains a history of workload and performance measurements, which are used by
the Automatic Database Diagnostic Monitor (ADDM) to spot performance anomalies.
You can also use AWR to track ongoing changes in workload.
Tools for Creating Databases
There are two basic ways to create an Oracle database:
??? Use the GUI Oracle Database Configuration Assistant.
??? Run character-mode scripts.
Oracle ships with a GUI utility called the Oracle Database Configuration Assistant,
which can be run standalone or from the Oracle Installer. It is written in Java and
therefore provides the same look and feel across platforms. The Assistant is a quick
and easy way to create, modify, or delete a database. It allows youto create a typical
preconfigured database (with minimal input required) or a custom database (which
involves making some choices and answering additional questions). The Database
Configuration Assistant is typically initially accessed as part of a standard installer
session.
