Hi...
Oracle provides a package that allows users to schedule and run stored procedures. They may be run once, or at regular intervals. The package is DBMS_JOB. There is a summary of the functions and procedures for the package in Oracle's documentation at...

A complete description of the package and how to manage the job queue may be found at....

The simplest way of submitting a job as a stored procedure to run would be to use the SUBMIT procedure of the DBMS_JOB package. Below is the description of this procedure and an example of invoking it to schedule a job to rum at 11 p.m., and subsequently every 24 hours.
PROCEDURE SUBMIT
Argument Name Type           In/Out Default?
JOB           BINARY_INTEGER OUT
WHAT          VARCHAR2       IN
NEXT_DATE     DATE           IN     DEFAULT
INTERVAL      VARCHAR2       IN     DEFAULT
NO_PARSE      BOOLEAN        IN     DEFAULT
INSTANCE      BINARY_INTEGER IN     DEFAULT
FORCE         BOOLEAN        IN     DEFAULT
VARIABLE jobnum NUMBER;
BEGIN
DBMS_JOB.SUBMIT
  ( :jobnum
  , 'stored_procedure_name;'
  , TO_DATE( TRUNC(SYSDATE) + 23/24 )
  , 'SYSDATE + 1'
  COMMIT;
END;
PRINT jobnumSome things to note: The jobnum is a unique means of identifying this job. You will need this if you query the USER_JOBS and DBA_JOBS_RUNNING views to find out what's happening with your scheduled job. There can be no print buffer (DBMS_OUTPUT) output from the job. You should review the documentation so you understand how Oracle handles failures, error output and rescheduling based on intervals.
Hope this helps. Good Luck.
