DBAs in large enterprises may also
help set up replication strategies, disaster and high-availability strategies, hierarchical
storage management procedures, and the linking of database event monitoring (e.g.,
specific database tasks and status) into enterprise network monitors.
Managing Oracle | 123
Oracle??™s feature list has grown with each database release. Yet managing Oracle can be
much less labor-intensive today than it was in the past. While database releases
highlighted in early editions of this book described the novelty of an easier-to-use management
interface, producing better versions of Oracle Enterprise Manager (EM) was
only part of the effort to simplify management underway within Oracle Server Development.
The database itself has now become more self-tuning and self-managing.
Initially, this effort was focused mostly on better management of single instances of
the Oracle database. Oracle Database 10g expanded its capabilities with a focus on
grid computing. Grid computing highlighted the need for effective management of
scores of computers and database instances.
