Do you have some legacy DBMS_JOBS hanging out there running – that somebody left – and abandoned to “rust”. Need to get rid of them even though you don’t own them? Try this as long as you can connect as sysdba:
–select * from dba_jobs;
set heading off
set feedback off
select ‘execute sys.dbms_ijob.remove(‘||trim(to_char(job))||’);’ from dba_jobs
WHERE LOG_USER like ‘%username%’ or LOG_USER like ‘%username2%’;
–select * from dba_jobs;
Now just execute the output as sysdba.
