定时任务可以通过在Oracle数据库中使用DBMS_SCHEDULER包来设置。您可以使用以下语法来创建一个定时任务：

BEGIN
  DBMS_SCHEDULER.create_job(
    job_name        => 'job_name',
    job_type        => 'PLSQL_BLOCK', 
    job_action      => 'your_plsql_block',
    start_date      => SYSTIMESTAMP,
    repeat_interval => 'FREQ=DAILY; BYHOUR=0; BYMINUTE=0',
    enabled         => TRUE
  );
END;

In the example above, you will need to replace ‘job_name’ and ‘your_plsql_block’ with your task name and PL/SQL code block. You will also need to set the start_date and repeat_interval parameters according to your requirements to define the execution time and frequency of the task.

In the repeat_interval parameter, you can define the rules for repeating a task by setting different FREQ and BYHOUR, BYMINUTE parameters. For example, FREQ=DAILY signifies executing once daily, BYHOUR=0 signifies executing at midnight, and BYMINUTE=0 signifies executing at the start of every hour.

You can also use other parameters to further customize your scheduled tasks, such as setting task priority, parallelism, handling of failures, and more. For more information about the DBMS_SCHEDULER package, please refer to the official Oracle documentation.
