Log_history of job

Question

Hi all,
In my 10.2.1 database I have a job that runs every 5 sec .
To prevent the job log from growing indiscriminately, I created a job class with attribute log_history set to 2 days and assigned that job class to my job that runs every 5 sec.
According to administrator guide Once a day, the Scheduler automatically purges all log entries from the job log that are older than the specified history.
but when i see the job_logs purging is not occuring ,job_log still showing logs of more than 2 days.
if anyone can help?
Thanks

Hi, certainly.... thanks for your reply

Note: you only see two job executions for the PURGE_LOG job above because I did a manual dbms_scheduler.purge_log myself on Sunday. Also noteworthy, I have since changed the log_history attribute of my job_class to 1 day (before it was 2 days, and I had to wait 2 days to see if the purge had worked). See below:
SQL> COLUMN JOB_NAME FORMAT A15
SQL> COLUMN JOB_CLASS_NAME FORMAT A20
SQL>
SQL> SELECT a.job_name, a.job_class, b.log_history
  2  FROM dba_scheduler_jobs a
  3  ,dba_scheduler_job_classes b
  4  WHERE a.job_name = 'SESSION_END_JOB'
  5  AND a.job_class = b.job_class_name;
JOB_NAME        JOB_CLASS                      LOG_HISTORY
SESSION_END_JOB SESSION_END_JOB_CLASS                    1

PS -
Just want to clarify... my co-worker (the original poster) mistyped our version... it is:
SQL> select version from v$instance;
VERSION
10.1.0.4.0
