In this module you learn how to monitor the Oracle Collaboration
Suite components using Enterprise Manager (EM). Since EM is installed with every
instance of Oracle Application Server, you can immediately begin managing your
Oracle Collaboration Suite components from your Web browser.
You use the Oracle Enterprise Manager (EM) Web site as the
primary tool to manage the Oracle Collaboration Suite components and the Oracle
environment. EM helps you monitor, diagnose, and configure the components of
your Oracle Collaboration Suite installation. You can also deploy applications
and manage security using this tool.
Using the EM Web site you can monitor and administer:
A single
Oracle Collaboration Suite instance
A farm
of application server instances. A farm is a collection of instances that
share the same infrastructure.
An Application
Server cluster. A cluster is a collection of application server instances
with identical configuration and application deployment. Clusters enforce
homogeneity between member instances so that a cluster of Application Servers
can appear and function as a single instance.
The EM Web site allows you
to take a top-down approach to monitor activities. For example, you can start
by reviewing the basic characteristics of your application server on the Application
Server Home page, and then drill down to examine the performance of individual
components. By using this approach, the Application Server Control helps you
identify high-level performance issues, such as a high CPU load on your system.
You can then drill down to individual components or applications to isolate
the root cause of the high-level problems.
You access Enterprise Manager using one of two methods--by
directly navigating to the Enterprise Manager Web site with the URL or by displaying
Enterprise Manager from the Oracle Collaboration Suite Welcome page. This example
uses the URL in the Web browser.
1.
Enter
the Enterprise Manager URL in your web browser:
http://<infrastructure
host>:<OEM port>/
2.
On
the Enter Network Password window, enter the Oracle Application Server
administrator username and password and click OK.
3.
When
you first display Enterprise Manager, the initial home page you see is
based on the components you configure and choices you make during the
Oracle Application Server installation. For this example, Infrastructure
and the Mid-Tier are stand-alone instances that belong to the same farm.
To monitor the processes
within the Infrastructure, perform the following steps:
1.
Click
the Infrastructure link.
2.
From
the Application Server home page, you can stop, start or restart all of
the system components within the Infrastructure instance. As well, diagnostics
are given regarding the CPU and memory usage.
3.
Under
the System Components region of the window, you can drill down to monitor
and configure an individual component of the application server. For example,
use the Oracle HTTP Server home page to monitor the performance of your
Web server by clicking on the HTTP Server option.
4.
The HTTP Server window allows you to monitor general
statistics, status, response and load, and the default server configuration
of the HTTP Server component.
To
monitor the Mid-Tier applications, perform the following steps:
1.
Click
the Farm link to return back to the Application Server home page.
2.
Under
Standalone Instances, select the mid-tier link.
3.
In
the Enter Network Password dialog box, enter the Oracle Application Server
administrator username and password and click OK.
4.
Similar
to the Application Server home page for Infrastructure, you can stop,
start or restart all of the system components within the Mid-Tier instance.
Also, diagnostics are given regarding the CPU and memory usage.
5.
Under
the System Components region of the window, you can drill down to monitor
and configure an individual component of the Mid-Tier applications. For
example, select the OC4J_iFS_files
option to monitor the performance of Oracle Files.
6.
The OC4J_iFS_files
window allows you to monitor general statistics, status, JDBC Usage, Response
statistics for Servlets and JSPs and EJBs.
