As part of the effort to make Oracle products, services, and supporting documentation accessible and usable to the disabled community, Oracle Database Vault Administrator offers several features that make management data available to users of assistive technology. To enable these features and provide for full accessibility, you must modify two configuration settings, which are described in the following sections:
Enabling Oracle Database Vault Administrator Accessibility Mode
Providing Textual Descriptions of Database Vault Administrator Charts
Oracle Database Vault Administrator takes advantage of user interface development technologies that improve the responsiveness of some user operations. For example, when you navigate to a new record set in a table, Oracle Database Vault Administrator does not redisplay the entire HTML page. However, this performance-improving technology is generally not supported by screen readers. To disable this feature, and as a result, make the Database Vault Administrator HTML pages more accessible for disabled users, use the following procedure.
To enable the display of an entire HTML page:
Locate the uix-config.xml
configuration file.
To locate the uix-config.xml
file in an Oracle Database 10g installation, change directory to the following location in the Oracle home:
ORACLE_HOME\dv\jlib\dva_webapp\dva_webapp\WEB-INF
Open the uix-config.xml
file using a text editor and locate the following entry:
<!-- An alternate configuration that disables accessibility features --> <default-configuration> <accessibility-mode>inaccessible</accessibility-mode> </default-configuration>
Change the value of the accessibility-mode property from inaccessible
to accessible
.
Save and close the uix-config.xml file.
Restart Database Vault Administrator.

For more information on starting Oracle Database Vault Administrator, refer to Oracle Database Vault Administrator's Guide.In the Monitor page of the Database Vault Administrator, a chart is used to display security policy data. However, charts do not convey information in a manner that can be read by a screen reader. To remedy this problem, you can configure Database Vault Administrator to provide a complete textual representation of each chart. By default, support for the textual representation of charts is disabled. When textual description for charts is enabled, Database Vault Administrator displays a textual representation of the chart data.
To enable the textual representation of charts:
Locate the web.xml
configuration file.
To locate the web.xml
file in a Oracle Database 10g installation, change directory to the following location in the Oracle home:
ORACLE_HOME\dv\jlib\dva_webapp\dva_webapp\WEB-INF
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> -->
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 four lines:
<context-param> <param-name>enableChartDescription</param-name> <param-value>true</param-value> </context-param>
Save and exit the web.xml
file.
Restart Database Vault Administrator.
