What's New in Oracle Application Server Administration?

This preface introduces the new administrative features of Oracle Application Server 10g (9.0.4). This information is mostly useful to users who have managed Oracle9i Application Server (Oracle9iAS) Release 2 (9.0.2 and 9.0.3).

The new administrative features of Oracle Application Server 10g (9.0.4) include:

Oracle Identity Management

Identity management is the process by which various components work together to manage the security life cycle for networked entities, such as devices, processes, applications, and users. While some of this functionality existed in Oracle9iAS Release 2, it has been enhanced and fully integrated into a new product in Oracle Application Server 10g called Oracle Identity Management.

Oracle Identity Management provides a fine-grained delegation deployment privileges model for deploying middle tiers and Metadata Repositories. You can find information on this in several books, as shown in the following table.

Oracle Identity Management is part of the Infrastructure installation type, and contains the following components:

Improvements to Oracle Application Server Metadata Repository

Oracle Application Server 10g provides the following improvements to the Oracle Application Server Metadata Repository:

More Flexibility in the Infrastructure Installation Type

The Infrastructure installation type is divided into two distinct pieces:

Oracle Application Server 10g provides greater flexibility for installing an Infrastructure:

Because the Infrastructure is divided into these two pieces that provide different services, it is often too imprecise to refer to the Infrastructure as a whole when discussing administrative operations. For example, a middle-tier instance may use Oracle Identity Management in one Infrastructure installation, and the OracleAS Metadata Repository in another Infrastructure installation. In this case, it is not accurate to refer to the "Infrastructure" used by a middle-tier instance. You will notice that Oracle Application Server 10g tools and documentation often refer specifically to the Oracle Identity Management installation or OracleAS Metadata Repository used by a middle-tier instance.

New Features in Oracle Enterprise Manager Application Server Control

The Oracle9iAS Oracle Enterprise Manager Web site has been renamed to Oracle Enterprise Manager 10g Application Server Control (Application Server Control, for short).

Application Server Control is installed and configured in every Oracle Application Server installation. Each installation has its own ias_admin password and uses a different port for Application Server Control. There is no primary Oracle home and no emtab file.

Application Server Control includes the following enhancements:

Expanded Role of Oracle Process Manager and Notification Server (OPMN)

OPMN has expanded to provide process management and monitoring for most Oracle Application Server components, and opmnctl is the primary command-line tool for starting and stopping.

New Features in Distributed Configuration Management (DCM)

In Oracle Application Server 10g, DCM and the dcmctl command provide many new features, including:

Some SSL Ports Are Not Enabled During Installation

For security purposes, the following SSL ports are not enabled during installation--you can selectively enable them after installation:

Simplified Starting and Stopping

The opmnctl command now starts and stops most Oracle Application Server components, in the proper order. This has greatly simplified starting and stopping an Oracle Application Server instance.
