To create scheduled tasks in Oracle, you can use the DBMS_JOB package. The steps are as follows: 1. Create a job (task); 2. Enable the job; 3. Disable the job; 4. Delete the job; 5. View job information. For example, to run a task named "my_job" that executes a stored procedure named "my_procedure" every morning at 8:00 am, you would use the DBMS_JOB.SUBMIT and DBMS_JOB.ENABLE commands.
