About the OAM Farm Page in Fusion Middleware Control

Figure 16-3 illustrates the OAM Farm page in Fusion Middleware Control. Each Farm page includes similar information. The Farm Resource Center provides immediate access to online information.

Figure 16-3 OAM Farm Page in Fusion Middleware Control

Sections on the Farm page are described in Table 16-1.

The navigation tree on the left side of the page, like the one in Figure 16-4, enables you to choose a specific instance (target) on which to operate regardless of the page you are currently viewing. Target names in your environment will be different.

Figure 16-4 Farm Navigation Tree in Fusion Middleware Control

For more information, see "Logging In To Fusion Middleware Control".

About Context Menus and Pages in Fusion Middleware Control

OAM Farm details in Fusion Middleware Control are divided into the following nodes within the navigation tree:

• Application Deployments

• Internal Applications (includes logout page and other details for the OAM AdminServer and OAM Server instances)

• WebLogic Server domains (WebLogic Server details, including the OAM Farm)

• Identity and Access (includes OAM Cluster or individual OAM Server instances)

Clicking a node in the navigation tree displays an information page with individual links and a description of the Target, Type, and Full Name, as shown in Figure 16-5 for Application Deployments.

Figure 16-5 Node Information Page in Fusion Middleware Control

Clicking an instance (target) name (from either the navigation tree or a page), displays a context menu and a more detailed summary page, as shown in Figure 16-6. Notice that the Internal Application target is highlighted in the navigation tree and a page of the same name is displayed on the right. The context menu is available beneath the target name at the top of the page.

Figure 16-6 Application Deployment Summary for the Selected Internal Application

The Application Deployment menu is shown in Figure 16-7.

Figure 16-7 Application Deployment Menu

WebLogic Server domain: The WebLogic Server domain page is shown in Figure 16-7 with the corresponding menu displayed. The Oracle WebLogic Server domain Resource Center, with links to online documentation, is visible in the bottom-left corner. This page more closely resembles the Farm landing page.

Figure 16-8 WebLogic Server Domain Summary with Context Menu Exposed

Selecting a target name within the WebLogic Server domain node displays a target summary page that more closely resembles the Application Deployment page in Figure 16-5.

For more information, see "Displaying Context Menus and Target Details in Fusion Middleware Control".

Displaying Context Menus and Target Details in Fusion Middleware Control

Fusion Middleware Control administrators can use the following procedure to view context menus and target pages.

   • Application Deployments

   • WebLogic Server domain

   • Identity and Access

4. Menus and Summary Pages: Click an instance name (in either the navigation tree or the related page) to display a summary page and menu (Figure 16-6 and Figure 16-7).

5. OAM Cluster or OAM Server Pages: See "Viewing OAM Performance in Fusion Middleware Control".

About OAM Performance Overview Pages in Fusion Middleware Control

The Fusion Middleware Control Performance Overview for OAM can be used to reflect WebLogic cluster information down to specific performance metrics for individual OAM Cluster and OAM Server targets.

Oracle Access Manager Cluster Pages: The top node within Identity and Access leads to a page for the OAM Cluster Deployment, which includes a Performance Overview. In Figure 16-9, notice the Oracle Access Manager Cluster selected in the navigation tree, beneath the Identity and Access node. Figure 16-9 illustrates the Oracle Access Manager Cluster Performance Overview and Deployments section.

Figure 16-9 Oracle Access Manager Cluster Performance Overview

OAM Server Pages: Selecting an OAM target name from the navigation tree (or the open page), displays a Performance Overview for the target with a summary of Key Metrics at the top (replacing the Deployment section, which appears on the Cluster page).

Table 16-3 describes the elements of the Performance Overview for OAM Clusters and OAM Server instances in Fusion Middleware Control. There are only a few differences.

About Dynamic Log Level Changes

Using Fusion Middleware Control, administrators can change OAM 11g log levels dynamically.

Table 16-5 outlines OAM 11g log availability and functions in Fusion Middleware Control

Figure 16-11 shows the Log Levels configuration page Fusion Middleware Control.

Figure 16-11 Log Level Configuration Tab

The Log Levels tab on the Log Configuration page allows you to configure the log level for both persistent loggers and active runtime loggers:

• Persistent loggers are saved in a configuration file and become active when the component is started.

  The log levels for these loggers are persisted across component restarts.

• Runtime loggers are automatically created during runtime and become active when a particular feature area is exercised.

  For example, oracle.j2ee.ejb.deployment.Logger is a runtime logger that becomes active when an EJB module is deployed. Log levels for runtime loggers are not persisted across component restarts.

Table 16-6 explains the configuration status and options for log levels.

Table 16-6 Log Levels Tab on Log Configuration Page

Element	Description
Apply	Submits and applies log level configuration changes, which take affect immediately.

Log File	Clicking a name in the Log File column displays the Log Files page, which you can use to create and edit the file where log messages are logged, the format of the log messages, rotation policies, and other logging parameters. See Also: "Managing OAM Log File Configuration from Fusion Middleware Control".
