What does your SQL script do?

If it a simple SQL script then the Oracle Job Scheduler is your best bet. See:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sched.htm#sthref6598

If the is controlled from a shell or Perl script then you can schedule it from CRON using by editiing Oracle's CRONTAB using the command "crontab -e".

Create a SQL script with ur DML / DDL statements. Next create a shell script that invokes the SQLPLUS with the SQL script. Another option is to create a stored procedure for your DDL / DML statements and schedule a DBMS_JOB to run it at periodic intervals.

Below is a sample script that you could put into cron.  Remember that cron does not set the environment so you have to do it in the script.
#!/bin/sh
 
ORACLE_SID=<sid>
ORACLE_HOME=<ora_home>
PATH=${PATH}:${ORACLE_HOME}/bin
export ORACLE_SID ORACLE_HOME PATH
 
${ORACLE_HOME}/bin/sqlplus <user>/<pass> << END
-- Statements go here
exit
END
