Create Oracle Job Scheduler

Here is the step-by-step process to create a job in Oracle that executes the procedure P_TEST to create a backup of the EMPLOYEES table:

1. Connect to the Oracle database as a user with the necessary privileges (e.g., SYSTEM or a user with the CREATE JOB privilege).

2. Create the procedure P_TEST (if it doesn't already exist):

CREATE OR REPLACE PROCEDURE P_TEST AS

BEGIN

  DECLARE

    backup_table_name VARCHAR2(255);

  BEGIN

    SELECT 'EMPLOYEES_' || TO_CHAR(SYSTIMESTAMP, 'YYYYMMDD_HH24MISS') INTO backup_table_name FROM dual;

    EXECUTE IMMEDIATE 'CREATE TABLE ' || backup_table_name || ' AS SELECT * FROM EMPLOYEES';

  END;

END P_TEST;

1. Create a new job using the DBMS_SCHEDULER package:

BEGIN

  DBMS_SCHEDULER.CREATE_JOB(

    job_name        => 'EMPLOYEES_BACKUP_JOB',

    job_type        => 'PLSQL_BLOCK',

    job_action      => 'BEGIN P_TEST; END;',

    start_date      => SYSTIMESTAMP,

    repeat_interval => 'FREQ=DAILY; BYHOUR=2;',  -- Optional

    end_date        => NULL,  -- Optional

    enabled         => TRUE);

END;

This will create a new job called EMPLOYEES_BACKUP_JOB that executes the P_TEST procedure. You can adjust the start_date, repeat_interval, and end_date as needed.

Note: Make sure to replace the -- Optional comments with the appropriate values for your specific requirements.

Also, you can use DBMS_SCHEDULER.CREATE_PROGRAM and DBMS_SCHEDULER.CREATE_JOB to separate the program and job creation.
