is this the kind of thing youre talking about? I don't really know much about servers or what job scheduling is, but this seems to be what youre talking about, let me know if this is completely off-base:
"
DBMS_JOB does this exactly.
SELECT TEXT
FROM all_source
WHERE name = 'DBMS_JOB'
AND type = 'PACKAGE'
ORDER BY line;
In your case, it is very easy:
DECLARE
l_job number;
BEGIN
dbms_job.submit( l_job,
'abc;',
trunc(SYSDATE)+4/24,
'trunc(sysdate)+1+4/24' );
END;
