This time copied and passed everything from this web site
http://www.uaex.edu/srea/daemon.sql the daemon package.
Run it on the server again without any success.

Error message:

ERROR at line 1:
ORA-20011: Execute_system: Error while receiving.
Status = 1
ORA-06512: at "RIMS.DAEMON", line 26
ORA-06512: at line 30

I tested with this script the daemon.execute_system function :

SET SERVEROUTPUT ON SIZE 100000
SET PAGES 5000
SET LINESIZE 160
DECLARE
l_line VARCHAR2(2048);
l_status INTEGER;
BEGIN
deb.enable_debug(1000000);
deb.trace(0,'unix_command', 'BEFORE');
l_line := 'cp /rims/live/bespoke/viktor/bloomberg/a.lis /rims/live/bespoke/viktor/bloomberg/a.lis.de';

l_status := daemon.execute_system (l_line);

deb.trace(0,'unix_command', 'AFTER');

END;
