How to start Oracle scheduled tasks?

Enabling Oracle scheduled tasks requires performing the following steps in the database:

Step 1: Create the required users and roles

• Create a new user dedicated to running scheduled tasks.
• Grant CREATE JOB and ALTER JOB permissions to this user.
• Create a new role and grant the role EXECUTE JOB permissions.

Step 2: Create a scheduled task

• Use the DBMS_JOB package to create a scheduled task.
• Specify the name, description, start time, frequency and action of the task.

Step 3: Start scheduled tasks

• Use the DBMS_SCHEDULER package to start scheduled tasks.
• Specify the name of the task and set it to the open state.

Detailed expansion:

Step 1: Create the required users and roles

<code class="sql">CREATE USER task_user IDENTIFIED BY password;
GRANT CREATE JOB, ALTER JOB TO task_user;

CREATE ROLE task_role;
GRANT EXECUTE JOB TO task_role;</code>

Steps 2: Create a scheduled task

<code class="sql">BEGIN
  DBMS_JOB.CREATE_JOB (
    job_name => 'my_job',
    job_type => 'EXECUTABLE',
    job_action => 'path/to/script.sql'
  );
END;</code>

Step 3: Start a scheduled task

<code class="sql">BEGIN
  DBMS_SCHEDULER.ENABLE (
    job_name => 'my_job'
  );
END;</code>

These steps will create and start an Oracle scheduled task. The task will run automatically at the specified start time and frequency.
