Annoying XDB login screen

Question

XDB login screen appears all the time when running installed demo applications
11g fresh install on redhat linux, installed demo applications, and every click presents an annoying XDB login screen (which needs to be cancelled to access the application screen).
running rdbms/admin/epgstat.sql reveals that
| ANONYMOUS access to XDB repository: |
| To allow public access to XDB repository without authentication, |
| ANONYMOUS access to the repository must be allowed. |
Allow repository anonymous access?
false
The XDB login screen no longer appears that frequently after running the custom script listed by
Pravednik in this link http://kr.forums.oracle.com/forums/thread.jspa?threadID=641846
QUESTION 1) What is the recommended way to make the Allow repository anonymous access = true ?
The problem still persists when apex the browser attempts to display images from the database.
for example:
http://localhost:port/i/htmldb/builder/db_objects_ctrl.gif
QUESTION 2) how to tell XDB not to authenticate such image access?
