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 modes:
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.
I use a screen reader: Generate ADF Faces components that are optimized for use with screen readers.
I use high contrast: Generate high-contrast–friendly visual content.
I use large fonts: Generate browser-zoom–friendly content
Show me the Accessibility Preference options after I log in: Show the accessibility options after sign-in.
Note:
If you did not choose your accessibility preferences in your first login to the Cloud Control console, you can still specify your preferences at any point later by navigating to the <user_name> menu, selecting Preferences and then selecting Accessibility.Some UI, like in ADF or in UIX, in EM console is implemented differently and hence, requires additional configuration to support certain accessibility modes. For example, for UI implemented with UIX, additional manual configuration is needed for screen reader mode.
To enable screen reader mode for UIX pages, do the following:
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-ctrl-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.
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:
On the Cloud Control home page, from the <user_name> menu, select About Enterprise Manager.
In the About Enterprise Manager dialog box, ensure that Accessibility Preference - Screen Reader Support is set to Enabled.
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:
