Oracle Scheduled Tasks Setup Guide

One way to set up scheduled tasks in Oracle databases is to use the DBMS_SCHEDULER package. This package contains procedures and functions that can be used to create, modify, and delete scheduled tasks, as well as manage the scheduling of tasks. Some common uses include:

1. Schedule a task.
2. CREATE a new job in the database scheduler called ‘my_job’ that will execute a PL/SQL block containing the procedure ‘my_procedure’ every day at midnight, starting now and running indefinitely, with the job enabled and labeled as ‘My scheduled job’.
3. Modify scheduled task:
4. Start setting up the attribute for ‘my_job’ to repeat every two hours.
5. Remove scheduled task:
6. Start by removing the ‘my_job’ job from the database scheduler.
7. Enable or disable scheduled tasks:
8. Start the job named ‘my_job’ and then stop it.

You can also use other procedures and functions from the DBMS_SCHEDULER package to obtain information about the status, run history, and manual execution or stopping of scheduled tasks. For detailed instructions, please refer to the official Oracle documentation or relevant tutorials.
