To view the Oracle Enterprise Manager Web site, click Log on to Oracle Enterprise Manager on the Oracle9iAS Welcome page.
You can access the Welcome Page by pointing your browser to the HTTP Server URL for your installation. For example, the default HTTP Server URL is:
http://hostname:7777
You can also go directly to the Oracle Enterprise Manager Web site using the following instructions:
1. Enter the following address in your Web browser:
http://hostnanme:<port_number>/
For example, if you installed Oracle9i Application Server on a host called SYS12, you would enter the following address in your Web browser:
http://SYS12:1810
2. Enter the Oracle9i Application Server administrator username and password.
The username for the administrator user isias_admin. The password is defined during the installation of Oracle9iAS.
3. Click OK.
Depending upon the components you configured and the choices you made during the Oracle9iAS installation, Enterprise Manager displays the
appropriate Home Page.
The initial Home Page varies depending upon whether or not you installed an Oracle9iAS Infrastructure. For more information about the options available when installing Oracle9iAS, see the Oracle9i Application Server Installation Guide.
Table 3–1describes the Enterprise Manager Home Pages that might be used as a starting point when you first browse to the Oracle Enterprise Manager Web site.
Note: Experienced administrators can modify the default port, but in most cases, the port specified for the Oracle Enterprise Manager Web site is 1810.
About the Oracle Enterprise Manager Web Site
Using the Oracle9iAS Instance Home Page
From the Oracle9iAS Instance Home Page (Figure 3–1), you can start and stop the application server instance, monitor the overall performance of the server, and review the components of the server. You can also drill down and examine the performance of a particular component and configure the component.
Table 3–1 Enterprise Manager Home Pages for Managing Oracle9iAS Enterprise Manager
Home Page Description
Oracle9iAS Instance Home Page
Use this Home Page to monitor and configure a single application server instance.
For more information, see"Using the Oracle9iAS Instance Home Page" on page 3-5.
The Instance Home Page is the first page you see if you have installed a single application server instance that is not associated with an Oracle9iAS Infrastructure.
Oracle9iAS Farm Home Page
Use this Home Page to view a list of all the application server instances associated with a particular Oracle9iAS
Infrastructure.
For more information, see"Using the Oracle9iAS Farm Home Page" on page 3-7.
The Farm Home Page is the first page you see if you have installed one or more application server instances that are associated with a common Oracle9iAS Infrastructure.
The Farm Home Page is also the first page you see when you view the Web site on a host where the Oracle9iAS
Infrastructure has been installed.
Application Servers Home Page
Use this page to view a list of the application server instances installed on the current host. Click the name of an instance to drill down and display the Oracle9iAS Instance Home Page, or—if the instance you select is associated with an Oracle9iAS Infrastructure—click Farm to display the Oracle9iAS Farm Home Page.
This is the first Home Page you see if you have installed more than one application server instance on the host and one or more of the instances are not associated with an infrastructure.
About the Oracle Enterprise Manager Web Site
Figure 3–1 Oracle9iAS Instance Home Page
If you scroll down the page, the Home Page provides a table that lists the
components of the application server. From this table, you can also get a snapshot of how each individual component is performing.
From the System Components table, you can display a Home Page for each component of the application server.
Depending upon the options you have installed, the Administration section of the Oracle9iAS Instance Home Page provides additional features that allow you to perform the following tasks:
■ Associate the current instance with an existing Oracle9iAS Infrastructure.
■ Configure additional Oracle9iAS components that have been installed, but not configured
■ Change the password or default schema for a component
For more information, click Help at the top of the Oracle9iAS Instance Home Page.
About the Oracle Enterprise Manager Web Site
Using the Oracle9iAS Farm Home Page
If your application server instance is associated with an Oracle9iAS Infrastructure, your start page for the Oracle Enterprise Manager Web site is the Oracle9iAS Farm Home Page (Figure 3–2).
For more information about installing the Oracle9iAS Infrastructure, see the Oracle9i Application Server Installation Guide.
The Farm Home Page displays a list of the standalone application server instances and Oracle9iAS clusters associated with your Oracle9iAS Infrastructure. Standalone instances are application server instances that are not part of an Oracle9iAS cluster.
■ You can associate a particular application server instance with the Infrastructure using the Use Infrastructure link on the Oracle9iAS Instance Home Page.
Using the Farm Home Page, you can perform the following tasks:
■ Manage multiple application server instances on multiple hosts
■ Drill down to the Oracle9iAS Instance Home Page for each instance
■ Create and manage Oracle9i Application Server clusters
See Also: "Associating an Instance with an Infrastructure (Joining a Farm)" on page 10-4
See Also: Chapter 14, "Application Server Clustering" for more information about Oracle9iAS clusters

Using an Oracle9iAS Component Home Page
Oracle9iAS component Home Pages vary from one component to another. That is because each component has different monitoring and configuration requirements.
However, most of the component Home Pages has the following common elements:
■ A general information section that includes an icon that indicates the current state of the component and provides buttons for starting and stopping the component (if applicable).
■ Status information, including CPU and memory usage information, so you can get a snapshot of how the component is performing.
■ Component-specific information, such as a list of virtual hosts on the HTTP Server Home Page or a list of deployed applications on the OC4J Home Page.
■ Links to administrative functions where appropriate, so you can modify the configuration of selected components. In many cases, this means you can use a graphical user interface to modify complex configuration files.
