Do you want to call the PL/SQL Procedure from Oracle Application ?
If yes then,
go into the o/s and write the procedure in a file with .sql extension and then move the file to application specified directory under sql or you can even store the procedure as a stored procedure and call it in oracle application.
for doing so,
Navigate to Application Developer Responsibility and then enter in to Concurrent Program Menu and then into Create Executables form
in that if u are using stored procedure,
select the execution method as stored procedure and then tell the procedure to be called.
and then attach this executable file to Concurrent program. and then call the concurrent program as a report or process.
if you are aware about concurrent programs pls let me know so that I can proceed further.
