Here is a C-Shell script you can run in the background, it should be named

host.csh. host.csh will be run by you after the db is up. it will create

temporary scripts "tmp.csh" that it will run. the last thing these tmp.csh

scripts do is re-run host.csh to get the next request....

-------------------- bof ----------------------------

#!/bin/csh -f

sqlplus tkyte/tkyte < tmp.csh

set serveroutput on

declare

status number;

command varchar2(255);

begin

status := dbms_pipe.receive_message( 'HOST_PIPE' );

if ( status <> 0 ) then

dbms_output.put_line( '#exit' );

else

dbms_pipe.unpack_message( command );

dbms_output.put_line( '##!/bin/csh -f' );

dbms_output.put_line( '#' || command );

dbms_output.put_line( '#exec host.csh' );

end if;

end;

/

spool off

"EOF"

chmod +x tmp.csh

exec tmp.csh

----------------------- EOF ---------------------------------

If you run this in the background (The script), you'll be able to have it

execute any host command you want. Run this in one window for example and in

anther window go into sql*plus and try:
