1.4 Managing Oracle Application Servers

   

Oracle Application Server includes many features designed to ease the burden of management. One of the focuses of Oracle Application Server 10 g is to automate many of the management tasks needed for large-scale grid computing deployment. Management capabilities provided in Oracle Application Server include the following:

  • Software provisioning (installation, configuration, cloning, patching, upgrades)

  • User provisioning (including security and identity management)

  • Application management and monitoring

  • Workload management (including dynamic resource allocation and failover notification)

  • Systems management and monitoring

Chapter 3 describes each management topic in greater detail.

1.4.1 Oracle Enterprise Manager

Oracle Enterprise Manager, a management tool and framework, is a part of every version of Oracle Application Server and the Oracle database. This product has evolved from a Windows-based database management solution and a browser-based tool built on Java to the current HTML-based version. The Oracle Application Server 10 g Grid Control web-based tool can manage multiple Oracle Application Servers and databases and provide access to each Application Server Control tool (installed with each Oracle Application Server). Oracle Enterprise Manager 10 g can manage other Oracle software as well, including Oracle Collaboration Suite and E-Business Suite.

At the time of this writing, most of the functionality in previous non-HTML versions of Oracle Enterprise Manager now appears in the HTML version.


Multiple database and infrastructure administrators can access the Oracle Enterprise Manager repository at the same time to manage multiple Oracle products.

The HTML-based Oracle Enterprise Manager console was first released with Oracle9 i AS; that version provided important new application performance management and configuration management features. The HTML version supported in that release supplemented the earlier Java-based Oracle Enterprise Manager. Oracle Enterprise Manager 10 g , released with Oracle Database 10 g , includes both Java and HTML versions.

The HTML-based version of Oracle Enterprise Manager is used specifically to manage Oracle Application Server. Oracle Enterprise Manager can be deployed in several ways:

  • As a central console, monitoring multiple databases and application servers' leveraging agents (e.g., Grid Control)

  • As a database "product console" (easily installed with each individual database)

  • Through remote access (also known as studio mode)

In this book, we'll focus on the HTML-based console that manages Oracle Application Server. The HTML-based console includes advanced management capabilities for rapid installation, deployment across grids of computers, application service level monitoring and management, provisioning, upgrades, and automated patching. For example, application deployment of OC4J is managed via the Oracle Enterprise Manager HTML version.

Chapter 3 describes Oracle Enterprise Manager in greater detail.

1.4.2 EM2Go

EM2Go is a mobile version of Oracle Enterprise Manager that provides a subset of the functionality available in Oracle Enterprise Manager 10 g . EM2Go is accessed through a Pocket PC browser on a PDA device. EM2Go monitors the availability and performance of the various application servers managed by Oracle Application Server.

Chapter 3 describes EM2Go in greater detail.
