Adding to what Manik already suggested DBMS_SCHEDULER
From the docs - http://docs.oracle.com/cd/B28359_01/server.111/b28310/schedadmin006.htm
Read each & every word of the above link and try to understand.

Example 28-2 Creating a Set of Lightweight Jobs in a Single Transaction
The following example creates a set of lightweight jobs in one transaction:
DECLARE
newjob sys.job;
newjobarr sys.job_array;
BEGIN
-- To create a lightweight job, the program must be enabled.
-- The program action must be a PL/SQL block or stored procedure.
DBMS_SCHEDULER.ENABLE('PROG1');
newjobarr := sys.job_array();
newjobarr.extend(5);
FOR i IN 1..5 LOOP
newjob := sys.job(job_name => 'LWJOB' || to_char(i),
job_style => 'LIGHTWEIGHT',
job_template => 'PROG1',
repeat_interval => 'FREQ=MINUTELY;INTERVAL=3',
start_date => systimestamp + interval '10' second,
enabled => TRUE
newjobarr(i) := newjob;
end loop;
DBMS_SCHEDULER.CREATE_JOBS(newjobarr, 'TRANSACTIONAL');
END;

Even then iIf you have any specific doubt please post that.
But first try to do this practically.
And, if executing external scripts are involved, check this too - http://docs.oracle.com/cd/B28359_01/server.111/b28310/scheduse002.htm#i1032197
