Automating SQL scripts in Toad for Oracle (13.1) I'm not a DBA, so bear with me.

I've scheduled tasks through Toad's automation designer, but this uses Windows task scheduler. It's using Oracle 12c. All I'm doing is updating (creating/dropping) tables with the most recent data. Then I use an ODBC to report on that data in another application. 

How can I ensure my scripts execute on time without running a local machine with scheduled tasks? Can this be done without additional software? Thanks in advance.
DBMS_SCHEDULER is your friend https://docs.oracle.com/database/121/ADMIN/scheduse.htm

Also, I recommend you use SQL Developer instead.  That software has a GUI interface for creating the scheduled jobs to run.
