Cloning instance = /apex wants login

Question

Hi,
I have cloned the default XE instance on the same machine using the following instructions:
http://www.pgts.com.au/pgtsj/pgtsj0211b.html
Right now I have a working second instance called XETEST.
I can access it via the listener, via sqlnet on port 1521 and http on port 8080. Webdav access works, too.
But when I use http://127.0.0.1:8080/apex, it always prompts me for username/password for the realm XDB.
Creating a new dad to access a specific procedure in the schema HR works fine.
What could cause the login prompt on /apex?
Even creating a new DAD called apex2 didn't work (i have taken the same parameters as the initial APEX dad):
BEGIN
  DBMS_EPG.create_dad (
    dad_name => 'APEX2',
    path     => '/apex2/*');
END;
BEGIN
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'default-page',
    attr_value => 'apex');
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'database-username',
    attr_value => 'ANONYMOUS');
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'document-path',
    attr_value => 'docs');
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'document-procedure',
    attr_value => 'wwv_flow_file_mgr.process_download');
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'document-table-name',
    attr_value => 'wwv_flow_file_objects$');
  DBMS_EPG.set_dad_attribute (
    dad_name   => 'APEX2',
    attr_name  => 'nls-language',
    attr_value => 'american_america.al32utf8');
  --DBMS_EPG.set_dad_attribute (
  --  dad_name   => 'APEX2',
  --  attr_name  => 'request-validation-function',
  --  attr_value => 'wwv_flow_epg_include_modules.authorize');
END;

Hi Robert,
excellent that you have "found" my thread. This is good :).
No. FLOWS_020100 is the schema where all APEX
database objects are stored and should be used to log
on to the database for regular APEX usage. The DAD
parameter "database-username" should be set to
ANONYMOUS.I know, I was just trying to narrow down the problem.
After setting a new password on ANONYMOUS and switching the database-username back to ANONYMOUS it worked, too. But I still had to enter the credentials for the ANONYMOUS user in the popup-window again (once per browser session).
It seems like the procedure "apex" is not called directly but the XML DB wants to authenticate the user first. Setting dbms_epg.set_global_attribute('log-level', 7); didn't give me any information.
It seems like something is not right with ANONYMOUS.
Can you run the following SQL statement and see what
status the database user is in?I checked that and unlocked the account previously, too.
Here is the status:
SQL> select username, account_status from dba_users
  2  where username = 'ANONYMOUS';
USERNAME                       ACCOUNT_STATUS
ANONYMOUS                      OPENEven tried to recreate the DAD using the instructions:
alter session set current_schema = XDB;
begin
    dbms_epg.drop_dad('APEX');
    dbms_epg.create_dad('APEX','/apex/*');
    dbms_epg.set_dad_attribute('APEX','database-username','ANONYMOUS');
    dbms_epg.set_dad_attribute('APEX','default-page','apex');
    dbms_epg.set_dad_attribute('APEX','document-table-name','wwv_flow_file_objects$');
    dbms_epg.set_dad_attribute('APEX','document-path','docs');
    dbms_epg.set_dad_attribute('APEX','nls-language','american_america.al32utf8');
    dbms_epg.set_dad_attribute('APEX','document-procedure','wwv_flow_file_mgr.process_download');
    dbms_epg.set_dad_attribute('APEX','request-validation-function','wwv_flow_epg_include_modules.authorize');
end;
commit;.. both for the DAD APEX and also a second DAD APEX2. But it didn't change anything.
Thanks for your support,
~Dietmar.
