I am new to oracle. I need to get the scheduled jobs in my database. 

I queried 

```
DBA_SCHEDULER_JOBS, 
DBA_SCHEDULER_SCHEDULES, DBA_SCHEDULER_PROGRAMS,
 DBA_SCHEDULER_JOB_CLASSES, DBA_JOBS.

```

But Oracle issues the error 

```
"ORA-00942: table or view does not exist".

```

When I queried ALL\_JOBS and USER\_JOBS no rows are retrieved. Please suggest me which table should I see.
