3, Oracle provided auto-discovery features that allowed it to
find new databases automatically. Support for auto-discovery increased and
improved with each Oracle release since then. Since Oracle8i, the Universal Installer
and Oracle Net Manager work together smoothly to automatically configure your
Oracle Net network.
A key piece of the Oracle network that enables auto-discovery is the Oracle Intelligent
Agent. The agent is a piece of software that runs on the machine with your
Oracle database(s). It acts as an agent for other functions that need to find and work
with the database on the machine. For example, the agent knows about the various
Oracle instances on the machine and handles critical management functions, such as
monitoring the database for certain events and executing jobs. The agent provides a
central point for auto-discovery: Oracle Net discovers instances and databases by
interrogating the agent. We??™ll examine the general use of agents and their role in
managing Oracle in Chapter 5.
