How Database Administrators (DBAs) Spend Their Time
The bulk of a DBA’s time is spent performing ongoing management. Ongoing management tasks include:
SQL and application tuning
System resource tuning
Space and object management
Backup and recovery
Storage management

4. Oracle Database 10g Manageability Goals
Reduce administration costs
Automatic versus manual
Intelligence versus data
Adaptive versus oversized
Integrated versus third-party
Preventive versus corrective
Act-and-succeed versus trial-and-error
Reduce capital expenditures
Reduce failure costs
Oracle Database 10g Manageability Goals
Oracle Database 10g is a giant step toward the Oracle vision of creating a self-aware, self-learning, and completely self-managing database. A huge development effort has gone into simplifying every aspect of Oracle Database 10g administration with the dual objectives of enhancing administrator productivity and reducing operational costs.

Database Management Challenges
With previous releases of the Oracle Database, a good portion of a DBA’s time was spent on monitoring database system health, identifying bottlenecks, and improving system performance. Some of the tasks included:
Application and SQL management: Creating indexes and collecting optimizer statistics
System resource management: Monitoring CPU utilization and sizing the various database buffers
Space management: Sizing the various database files and monitoring space utilization within segments
Backup and recovery management: Monitoring the mean time to recover the database, planning for disaster recovery, and backing up the database
Storage management: Configuring disks, monitoring I/O bandwidth, and determining the stripe size

Oracle Database 10g Solution: Self-Managing Database
Oracle Database 10g can now automatically inform you of performance and resource allocation problems. In addition to providing suggestions for fixing these problems, Oracle Database 10g can also automatically fix the problems for you.
The second part of Oracle Corporation’s manageability strategy focuses on making the management of data centers easier, scalable, and more effective. Oracle Enterprise Manager 10g provides this solution. Enterprise Manager is a single, integrated solution for administering and monitoring all applications and systems based on the Oracle technology stack. The next-generation, HTML-based Enterprise Manager 10g provides the ability to seamlessly manage hundreds of systems located across organizational and geographical boundaries from a single point of control. Built with robust functionality for managing both small and large sets of systems, Enterprise Manager 10g automates critical operations to reduce task time and the risk of errors, which increases as the number of systems goes up. Its robust grouping and task-automation functionalities provide core features that enable reliable, rapid, and secure automation of traditionally time-consuming, error-prone tasks, such as application performance management, policy-based standardization, and system provisioning.

How Oracle Database 10g DBAs Spend Their Time
As the demand for database uptime continues to increase, so does the rate of growth in the average database size. These trends result in what some experts are calling the “management gap.” The doubling of both disk density and database size every few years is not being matched by a doubling of DBA staff in the same time period.
Therefore, DBAs are being asked to manage more (and larger) databases with the same staff. For this reason, they need tools that enable them to work more efficiently and manage more with fewer resources. With Oracle Database 10g, DBAs:
Think and act more proactively and strategically
Are application-aware and business-sensitive
Support larger databases with more users for more mission-critical applications
Can consolidate, centralize, and globalize
Require and provide more education
Are even more important and valuable
Maintain software: 3%
Manage database system: 25%
Load data: 3%

Even if topics might not seem to be relevant to you now, your job functions may change due to:
New products or methods
Changes in your employment
Changes in corporate structure
Enhancements in applications
Student Preface
As you progress through this course, you may encounter a number of topics that do not seem relevant for you at the present time. However, you should remember that information technology is an industry in which about 50 percent of your skills and knowledge today will be obsolete in a year or so. Features that are not of current interest could become valuable to you for a number of reasons:
Your company introduces a new product or business method that requires new database functionality.
You choose to advance your career by moving to a different group or company that requires you to use unfamiliar features.
Your company business changes due to a merger or acquisition.
A maintenance window for an old application allows developers to incorporate features that were not available when the application was first written.
The goal for this course is to teach you database administration skills that take you beyond basic configuration and monitoring tasks. This course covers a variety of features and techniques that you can employ to optimize database performance, increase data availability, and enhance your own productivity.
