How to close the report background engine programatically in developer 6.0?

Question

Friends,
We have developed our application using Oracle Developer 6.0 as front end and Oracle 9iR2 as a back end.
whenever the user is opening the application one session is creating after that if he runs any report the report background engine is started and that engine also creating one session. So, unnecessarily two sessions are opening for a single application.
So, how can we close the report background engine programatically after the report displays all the records?
Moreover, when the user close the application, the report background engine is still open. the user has to close the report background engine manually.
so how can we solve this issue?
Thanks

i got this while searching but its not working.....
Problem Description
Starting reports using a RUN_PRODUCT on Windows platforms starts a
Reports Background Engine (RBE). After leaving the forms application the
background engine is still running and must be terminated by the user.
Solution Description
This is intendet behaviour.
To close the Background Engine programmatically use the Reports Runtime parameter
ORACLE_SHUTDOWN. E.g.
Perform the following actions to stop the RBE when closing the Forms
application:
1) Create a dummy report which only does e.g. a SELECT * FROM DUAL
This report has a DESTYPE=FILE and a DESNAME to e.g. C:\TEMP\DUMMY.OUT
2) In the POST-FORMS trigger add the following code:
DECLARE
pl_id ParamList;
BEGIN
pl_id := Create_Parameter_List('dummy');
Add_Parameter(pl_id,'ORACLE_SHUTDOWN',TEXT_PARAMETER,'Yes');
Add_Parameter(pl_id,'PARAMFORM',TEXT_PARAMETER,'NO');
Run_product(REPORTS,'<<name dummy rapport>>',SYNCHRONOUS, RUNTIME,
FILESYSTEM,pl_id,NULL);
END;
Explanation
The Report Background Engine runs separately from the Forms application and
there is no direct relation between these processes. The Forms should signal
the RBE that is being closed.
When the Form is closed the POST-FORM triggers sends a dummy report to
the RBE. Since the ORACLE_SHUTDOWN=Yes parameter is used after running the
report the RBE is terminated.
A small side-effect of the solution is that a small file (5Kb) is created on
the file-system contaning the output of the dummy report.
