dbms_job question

All,
I need to schedule a job to run weekly at a specific time. I want to use DBMS_JOB to run it but I'm having some issues. The error I get when I try to submit the job in SQL is this: SP2-0734: unknown command beginning "DBMS_JOB.S..." - rest of line ignored.

I've tried it with Oracle 8i and 9i both with the same results. Shouldn't the DBMS_JOB scheduler be loaded by default?

Any help would be appreciated.

Thank you,

Richard Jaehne
