OWB_REMOTE_ADMIN value for remote control centre service?

Question

We're upgrading from OWB 10.2 to 11gR2, and it's failing with a message saying that the 'owb\UnifiedRepos\remote_owb_install.sql' script needs to be run to set the OWB_REMOTE_HOME to the OWB home on the database server.
However, as with our version 10 architecture, we don't want to install OWB on the database server, we want to have the Control Centre Service running on a separate application server. OWB11 has been installed on the apps server but when we run remote_owb_install.sql and then try to run OMBSEED the same error is coming up saying to run the script again. I've tried setting the OWB_REMOTE_HOME's value implicitly and explicitly, but neither works.
Any ideas or pointers gratefully received!

Answer 1

to add to the above information......
since I am using my own tablespace and schema as described above .....
I created a new control center through the design center user interface.......
for the new control center ...i provided the details of the above new user ...new workspace etc....
the ran the below ORACLE provided script(show_service script).....
set serveroutput on;
set role OWB_USER;
declare
l_available number(22);
begin
l_available := owbsys.wb_rt_script_util.show_service();
if l_available <> 0
then
dbms_output.put_line('Available');
else
dbms_output.put_line('Not Available');
end if;
end;
output is 'AVAILABLE'
but when I deploy my first mapping ..... I get the below error message
Error
RPE-01012: Cannot deploy PL/SQL maps to this target schema.
The target schema must be in the same instance as the Control Center and have the OWB_USER role granted
I have only one instance of oracle database .....also I have granted the OWB_USER role to my targer schema
how do i check what the Control Center is trying
