G Enabling the Enterprise Manager Accessibility Features

As part of the effort to make Oracle products, services, and supporting documentation accessible and usable to the disabled community, Enterprise Manager offers several features that make management data available to users of assistive technology. Enterprise Manager provides the following accessibility features:

This appendix consists of the following configuration settings you must modify to enable Screen Reader support:

Note:

If Screen Reader support is enabled, then all pages related to Refresh Process Status are not refreshed automatically because PPR is turned off. This is an expected behavior.

G.1 Enabling Enterprise Manager Accessibility Mode

To enable screen reader mode, do the following:

  1. On the Cloud Control home page, from the <user_name> menu, select My Preferences and then select Accessibility.

  2. In the Accessibility Preference page, select I use a screen reader. Click Apply.

    ADF accessibility mode is a session based setting which takes place immediately and does not require you to restart the Enterprise Manager Management Service.

    For ADF pages, you will see an Accessibility Preferences dialog after logging into Cloud Control for the first time. The settings in this dialog are the same as those in the Accessibility Preference page mentioned above.

G.2 Setting uix-config.xml Flag

To enable screen reader mode for UIX pages, do the following:

  1. Locate the uix-config.xml configuration file.

    To locate the uix-config.xml file in a Cloud Control installation, change directory to the following location in the Oracle Management Service home:

    ./oms/sysman/archives/emgc/deployments/EMGC_DOMAIN/emgc.ear/em.war/WEB-INF/uix-config.xml
    
  2. Open the uix-config.xml file using a text editor and set the following entry:

    <!-- An alternate configuration that disables accessibility features  -->
    <default-configuration>
    <accessibility-mode>screenReader</accessibility-mode>
    </default-configuration>
    
  3. Save and close the file.

  4. Restart the Oracle Management Service.

Note:

UIX accessibility mode is a product-wide setting. You will have to restart the Enterprise Manager Management Service for this setting to take effect.

Note:

In the uix-config.xml file, enable-auto-table-ctlr-labels is set to true. This enables tool tip boxes containing labels to appear when you hover your cursor over UI elements such as checkboxes and radio buttons in tables. To disable this function, change the setting to false.

G.3 Configuring web.xml File

To configure web.xml file, follow these steps:

  1. Locate the web.xml configuration file.

    To locate the web.xml file in a Cloud Control installation, change directory to the following location in the Oracle Management Service home:

    ./oms/sysman/archives/emgc/deployments/EMGC_DOMAIN/emgc.ear/em.war/WEB-INF/web.xml
    
  2. Open the web.xml file with your favorite text editor and locate the following six lines of the file:

    <!-- Uncomment this to enable textual chart descriptions
    <context-param>
    <param-name>enableChartDescription</param-name>
    <param-value>true</param-value>
    </context-param>
    -->
    
  3. Remove comments from this section by deleting the first line and the last line of this section so that the section consists of only these 4 lines:

    <context-param>
    <param-name>enableChartDescription</param-name>
    <param-value>true</param-value>
    </context-param>
    
  4. Save and exit the file.

  5. Restart the Oracle Management Service.

G.4 Verifying That Screen Reader Support Is Enabled

Throughout Enterprise Manager, charts are used to display performance data. For most users, these charts provide a valuable graphical view of the data that can reveal trends and help identify minimum and maximum values for performance metrics.

However, charts do not convey information in a manner that can be read by a screen reader. To remedy this problem, you can configure Enterprise Manager to provide a complete textual representation of each performance chart. By default, support for the textual representation of charts is disabled. When textual description for charts is enabled, Enterprise Manager displays a small icon for each chart that can be used as a drill-down link to the textual representation.

To verify whether Screen Reader support has been enabled for ADF pages, follow these steps:

  1. On the Cloud Control home page, click Help and then select About Enterprise Manager.

  2. In the About Enterprise Manager dialog box, ensure that Accessibility Preference - Screen Reader Support is set to Enabled.

  3. If Accessibility Preference - Screen Reader Support is set to Disabled, follow the steps listed in Enabling the Enterprise Manager Accessibility Features.

To verify whether Screen Reader support has been enabled for UIX pages, follow these steps:

  1. On the Cloud Control home page, from the Enterprise menu, select Reports and then select Information Publisher Reports.

  2. In the Information Publisher Reports page, click Hardware Summary. The Hardware Summary page is displayed. If accessibility setting has been enabled, you will see the icon shown in Figure G-1:
