Home -> Community -> Usenet -> c.d.o.misc -> Re: Fire a Program using a trigger
http://govt.us.oracle.com has a utility staged on it called plex that fully automates the process of writing a pipe daemon.
You would create a stored procedure stub, for example:
create procedure my_procedure( a in number, b in number, c in out varchar2 )
as
begin
null;
end;
/
You would then use the plex utility makesrc to have the pl/sql rewritten in the database and a c stub generated. All you have to do is fill in the code in the c stub that actually implements the procedure "my_procedure". It automates and hides all of the interprocess communication you would normally write using dbms_pipe.
look for it under downloadable utilities.
