Chapter 3. Systems Management
Many Oracle Application Server users aren't aware of
all the management activities that go on around them. But
comprehensive and effective systems management is vital to providing
a reliable, available, and secure environment. Without this
management, even the most highly functional environment may not be
optimally implemented or used. In Oracle Application Server, the
focus of systems management is Oracle Enterprise Manager
10g.Oracle Enterprise Manager 10g is the latest
version of Oracle Enterprise Manager, a management
tool framework with a graphical user interface that can manage a
variety of Oracle products, including Oracle Database, Collaboration
Suite, E-Business Suite, and, of course, Oracle Application Server.
Oracle distributed the first version of Oracle Enterprise Manager
with Oracle7 and added a browser-based Oracle Enterprise Manager
console (built with Java) with Oracle8i and an
HTML console with Oracle9iAS.Every time a new Oracle product or product version is introduced, the
new features and capabilities also introduce new management
challenges. In the past, keeping up with this ever-increasing list of
features required a fairly steep learning curve for novices.
Recently, however, Oracle has simplified management by providing
self-managing and self-tuning features in its products and by
implementing more automated management facilities in Oracle
Enterprise Manager 10g.

Application Server Control, which comes as part of
Oracle Application Server
10g, and Oracle Enterprise Manager
10g Grid Control, Oracle's
management solution for your entire Oracle environment, including
Oracle Application Server. (Throughout this book we refer to these
tools simply as Application Server Control and Grid Control.)Application Server Control
This GUI tool is the standard administrative console for Oracle
Application Server. When you install
Oracle Application Server, an Application Server Control instance is
installed for each individual application server you manage. You can
use the console to provide a variety of administrative tasks on that
server. For example, you can start and stop an application server,
enable and disable Oracle Application Server components, modify
server configurations, create Oracle Application Server Containers
for J2EE, deploy and monitor J2EE applications, manage ports and
clusters, and examine logs.
Grid Control
This GUI console provides additional management capabilities not
available in Application Server Control. Grid Control is typically installed on
a single location to provide a central console that allows you to
monitor and access all the application servers in your environment.
In addition to managing multiple application servers, Grid Control
also allows you to manage databases, applications, and hosts. Using
Grid Control you can link to and launch each Application Server
Control. You can also perform historical monitoring, alerting,
management of jobs and policies,
Application Service Level Management
(ASLM) and monitoring, and configuration management.Both Oracle
Application Server 10g and
Oracle Database 10g
are designed to be deployable on computer grids in which many servers
are used and need to be managed. Grid Control allows you to perform a
variety of grid management tasks such as resource pooling,
provisioning of computer resources, dynamic workload management, and
dynamic control of changing grid components. While Grid Control is
designed particularly to simplify grid management, it also greatly
simplifies the management of more traditional Oracle multitier
implementations.
This chapter briefly describes the use of Application Server Control
and Grid Control. It also discusses other management
functionsbackup, recovery, and securitythat are the
responsibility of the Oracle Application Server administrator. It
concludes with a discussion of working with Oracle Support to resolve
system management problems that may arise. You will need to
understand each area if you are going to design and implement
effective management strategies for your own Oracle Application
Server environment.
