Oracle Application Server 10g Essentials [Electronic resources] نسخه متنی

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
10g 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 10g 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 10g 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 Oracle9iAS; 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 10g, released with
Oracle Database 10g, 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
10g. 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.
