Can OS command execute by ORacle Jobs

Question

I wanted to now that is there any way to delete dump file from data pump directory?? Why I need this let me explain. I wanted to do. I’ve schedule data pump to run every night to export a particular scheme. By using U% I’ve avoided to replace files but the requirement has been change now becoz size of one exported file is too high. Now I wanted to delete already created file before Data pump schedule. I know its risky or strange but I wanted to do so. I just need to know can I delete file from OS using Oracle just like as we delete data file by defining including. Simply tell me can I schedule a job which OS command instead of PL/SQL block ???

Hi again!
Try this one:
<pre>
BEGIN
dbms_scheduler.create_job (
job_name =>'DEL_DUMP_FILE',
job_type =>'EXECUTABLE',
job_action =>'ls /home/oracle',
enabled => FALSE,
start_date => SYSTIMESTAMP
END;
PL/SQL-Prozedur erfolgreich abgeschlossen.
SQL> SELECT owner, job_name, enabled FROM dba_scheduler_jobs;
OWNER JOB_NAME ENABL
SYS AUTO_SPACE_ADVISOR_JOB TRUE
SYS GATHER_STATS_JOB TRUE
SYS FGR$AUTOPURGE_JOB FALSE
SYS PURGE_LOG TRUE
SYSTEM DEL_DUMP_FILE FALSE
SYSTEM EXT_LOAD FALSE
EXFSYS RLM$SCHDNEGACTION TRUE
EXFSYS RLM$EVTCLEANUP TRUE
8 Zeilen ausgewählt.
EXEC DBMS_SCHEDULER.RUN_JOB('DEL_DUMP_FILE');
</pre>
Try all the keywords in uppercase style. This one worked for me!
