Please help me soon

Answer 1

That's very simple.
Check the host built-in.
You may have something like the following:
PROCEDURE run_rep (x_file in varchar2) IS
-- runs a report not using run_product
-- thus not opening reports background engine
cmdstr varchar2(200);
the_username varchar2(20);
the_password varchar2(20);
the_connect varchar2(20);
pl_id paramlist;
begin
the_username := Get_Application_Property(USERNAME);
the_password := Get_Application_Property(PASSWORD);
the_connect := Get_Application_Property(CONNECT_STRING);
cmdstr:='R30RUN32.EXE module='| |
replace(x_file, '.rep', '')| |'.rep userid='| |
the_username| |'/'| |the_password| |'@'| |the_connect| |' usesdi=yes';
host (cmdstr);
END;
This is something that really works.
In like manner you may run any OS command.
If you wish the command not to display anything on screen, just do:
host(cmdstr, no_screen);
RTM first.
Best of luck,
