Manageability of a grid must take into account disk virtualization, resource pooling,
provisioning of computer resources, dynamic workload management, and dynamic
control of changing grid components. Oracle??™s grid initiative resulted in many significant
changes in managing the database geared toward significantly reducing this
complexity. While targeted at simplifying grid management, most of these improvements
also provide great impact in simplifying management of more traditional
Oracle database implementations.
As a consequence of the grid initiative and self-tuning and selfmanaging
initiatives, readers of early editions of this book will find a
large number of management changes in this chapter and in others
throughout this book.
All of the tasks we??™ve just described come under the heading of managing the database.
Many of the provisioning duties, including installation, initial configuration,
and cloning, are discussed in Chapter 3. Security issues are discussed in Chapter 6.
This chapter explores the following aspects of managing Oracle:
??? Using Oracle Enterprise Manager, which provides an easy-to-use interface and
underlying framework for many database-management tasks, including new
database capabilities
??? Managing database fragmentation, which can affect database performance
??? Performing backup and recovery operations and information lifecycle management,
which are the foundation of database integrity protection
??? Working with Oracle Support
In subsequent chapters, we??™ll cover other related topics in more depth, including
security, performance, and high availability.
