Job Scheduling in ORACLE
Lets start with creating a stored procedure that we will use to create a job.
CREATE PROCEDURE hr.test_proc1 AS
BEGIN
insert into test1 values(25,'baju');
END;
Use this following script to create a Scheduled Job.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'job_test1',
JOB_TYPE => 'STORED_PROCEDURE',
JOB_ACTION => 'hr.test_proc1',
START_DATE => '10-JUN-12 12.23.00 PM',
repeat_interval => 'FREQ=MINUTELY;INTERVAL=2');
END;
Now, you can enable, disable or even drop this job using following Commands.
--to enable
DBMS_SCHEDULER.ENABLE ('job_test1');
--to disable
DBMS_SCHEDULER.DISABLE ('job_test1');
--to drop
EXEC DBMS_SCHEDULER.DROP_JOB('job_test1');
--to retrieve details of job
select * from user_SCHEDULER_JOBS;
Moreover, you can change Schedule Attributes and make a test run using following Commands.
-- to change Time Interval
EXEC DBMS_SCHEDULER.SET_ATTRIBUTE('job_test1','repeat_interval', 'FREQ=Minutely;INTERVAL=2');
--to make a test run
EXEC DBMS_SCHEDULER.RUN_JOB('job_test1');
