Email notification was sent out twice

Question

I created two jobs using DBMS_SCHEDULER.CREATE_JOB. The first job was to update the table and the second job was to check the status of the first job in dba_scheduler_job_run_details. I also add email notification on the second job by using DBMS_SCHEDULER.ADD_JOB_EMAIL_NOTIFICATION which sends the email to myself. The problem was the email notification was sent to me twice everytime when I do that. My script is as the follows.
DBMS_SCHEDULER.ADD_JOB_EMAIL_NOTIFICATION (
job_name => 'KUDSJ_ENOT_ADBD_ENDPROC'
,recipients => '[email protected]'
,sender => '[email protected]'
,subject => 'Company Schedule Job - %job_owner%.%job_name% - %event_type%'
,body => '%event_type% occurred at %event_timestamp%. %error_message%'
,events => 'JOB_SUCCEEDED');
DBMS_SCHEDULER.SET_ATTRIBUTE(
'KUDSJ_ENOT_ADBD_ENDPROC', 'logging_level', DBMS_SCHEDULER.LOGGING_FULL);
I am not sure where the problem is. Please help. Thanks.

Answer 1

You meant that I should set recipients to null when I do the remove_job_email_notification. I did drop_job and remove_job_email_notification a couple of times already. Could you tell me more specific? Thanks.
This is what I did.
DBMS_SCHEDULER.DROP_JOB(job_name => 'KUDSJ_ENOT_ADB_XXXXX');
DBMS_SCHEDULER.REMOVE_JOB_EMAIL_NOTIFICATION(job_name => 'KUDSJ_ENOT_ADB_XXXXX', events => 'JOB_STARTED, JOB_SUCCEEDED');
