kunnen we het Unix-commando van de Oracle10g-procedure uitvoeren?

BEGIN
     DBMS_SCHEDULER.create_job(
    job_name        => 'SHELL_JOB',
    repeat_interval  => 'FREQ=DAILY; BYHOUR=2',
    job_type         => 'EXECUTABLE',
    job_action       => '/u01/app/oracle/admin/tools/shell_job.sh',
    enabled          => TRUE,
    comments         => 'Perform stuff'
);
END;
