Oracle 11g Enterprise Manager DB Control Changing Accessibility Mode Disabled to Enabled

I was using the OEM11G, when after the logon with my credential users, I saw the follow message “Accessibility Mode Disabled” as the image below:

To solve it, you need to change the status of the accessibility-mode in the file “uix-config.xml”. This file can be found on directory:  $ORACLE_HOME/j2ee/OC4J_EM/applications/em/em/WEB-INF/. Then, you need to do the follow steps:

1. vi $ORACLE_HOME/j2ee/OC4J_EM/applications/em/em/WEB-INF/uix-config.xml (Look the status “inaccessible” in the picture below):
2. Change the status of the accessibility mode in the file  from inaccessible to accessible.
3. After you changed the accessibility mode, save and close the file.
4. Now, you can acess the OEM follow the image below:

I hope this post can help you!
