Accessibility Notes for JRockit Mission Control Client

Oracle is dedicated to providing high quality information technology that is accessible to people with disabilities. To this end, Oracle has undertaken a substantial project to ensure the accessibility of Oracle JRockit Mission Control Client. Oracle is implementing these enhancements and will continue to address all accessibility issues that come to its attention.

This document includes information on the following subjects:

 


Screen Readers

Oracle supports a number of different screen readers, technology that translates screen-based information into spoken word to assist vision-impaired users.

Configuration options are currently available for the JAWS™ screen reader produced by Freedom Scientific, Inc. For information on configuring this product, please refer to the Freedom Scientific screen reader website, at:

http://www.freedomscientific.com/documentation/screen-readers.asp

Note: If you are using JAWS, be aware that tab/page switching does not work as expected. Please refer to Switching Between Tabs/Pages for a workaround.

 


JRockit Mission Control Accessibility Mode

Throughout JRockit Mission Control Client, dials and 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 JRockit Mission Control Client accessibility mode to provide dial and chart data in tabular format.

Configuring the Accessibility Mode

The accessibility mode is configured from JRockit Mission Control Client preferences window. To enable it, do the following:

  1. With JRockit Mission Control Console running, select Windows > Preferences...
  2. The Preferences window appears (Figure 1-1).

    Preferences Window

  3. In the Accessibility Options pane, select Use accessibility mode and, under that, select the accessibility options you want to enable:
    • Render dials as tables presents data shown on the velocimeters as table data.
    • Render graphs as tables presents data shown in graphs as table data.
  4. Select OK.
  5. Stop and restart the Console.
Note: If you configuring the accessibility mode before actually starting the console, the new configuration will appear when you start the console.

For Additional Information

For important information on using a screen reader to read table data, please refer to Reading Table Data with a Screen Reader.

 


Workarounds

This section contains additional instructions for enhancing your experience with JRockit Mission Control’s accessibility features. These instructions include:

Switching Between Tabs/Pages

When reaching a tab component in the JRockit Mission Control GUI, JAWS erroneously tells the user “to switch pages, press Ctrl+Tab”. The correct way to switch between tabs/pages is to use the left/right arrow keys.

Reading Table Data with a Screen Reader

To read JRockit Mission Control table data more efficiently with screen reading software, copy and paste the table data into a text editor and read it from there. To copy and paste, do the following:

  1. Right-click the table you want to read to open the context menu.
  2. Select all items by selecting Select All.
  3. Select Copy.
  4. Paste the text in a text editor.

Reading Console General/Overview Tab Data

To read data from the JRockit Mission Control Console, General/Overview tab with screen reading software, select Window > Preferences > JRockit Mission Control and choose Render dials as tables and Render charts as tables in the right panel.

Resizing Online Help Text

Vision-impaired users might find it difficult to read the online help documents in the standalone (RCP) version of JRockit Mission Control unless the text size is increased. If they need to change the font size, they must view the help in another browser.

JRockit Mission Control will use the default web browser specified in the operating system; you can't specify a different one from within JRockit Mission Control. How you specify a browser in the operating system depends on the version of the operating system.

To change rhe default viewer for JRockit Mission Control Help, do the following:

  1. Select Window > Preferences
  2. The Preferences dialog box appears.

  3. Under Specify how help information is displayed, select Use external browser.
  4. Click Apply or OK.
Note: Due to a limitation in the Eclipse help viewer, currently you cannot resize its text. If you need to resize the text the workaround is to use an external browser.

Wherever possible, these abbreviations and acronyms are spelled out upon first usage; however, that is not always possible.
