4.1 Oracle Application Server Networking Overview

Oracle Application Server has several features to connect and manage the various

parts of an enterprise deployment topology, including:

■ Distributed Configuration Management (DCM)

■ Oracle Process Manager and Notification (OPMN)

■ LDAP and Oracle Internet Directory

■ Enterprise Manager Server Control

4.1.1 Distributed Configuration Management (DCM)

DCM is a management framework that enables you to manage the configurations of

multiple Oracle Application Server instances across an enterprise deployment

topology. DCM consists of clients, a daemon, and a metadata repository.

DCM features enable you to:

■ Manage clusters and farms of Oracle Application Server instances. Manage the

configuration of individual components, such as Oracle Application Server

Containers for J2EE instances, Oracle HTTP Server instances, and Oracle Process

Management and Notification, or Java Authentication and Authorization Service.

■ Perform cluster-wide Oracle Application Server Containers for J2EE application

deployment, especially in Development Life Cycle topology.

■ Manage versions of configurations with archive, save and restore, and import and

export functions. You can automate some of these functions as part of routine

systems maintenance.

dcmctl is the Distributed Configuration Management command-line utility. You can

use it to manage configurations and deploy applications. Instructions on using dcmctl

and complete descriptions of all commands are described in Chapter 2, "dcmctl

Commands "in the Distributed Configuration Management Reference Guide.
