I will explain How to List and Monitor DBMS Jobs and Scheduler Jobs in Oracle Database in this post.
Monitoring Oracle Jobs
There are two packages related with Oracle database jobs which are called dbms_job,dbms_scheduler.
DBMS_SCHEDULER Jobs
DBMS_SCHEDULER offers new features by adding the ability to jobs with specific privileges and roles according to DBMS_JOB.
List and Monitor DBMS Jobs and Scheduler Jobs in Oracle
DBMS_JOB – Gather Schema Stats job
For example; Gather Schema Stats job with DBMS_JOB are as follows.
SET SERVEROUTPUT ON
DECLARE
l_job NUMBER;
BEGIN
SELECT MAX (job) + 1 INTO l_job FROM dba_jobs;
DBMS_JOB.submit(l_job,
'BEGIN DBMS_STATS.gather_schema_stats(''MSD'',estimate_percent => dbms_stats.auto_sample_size, degree=>8 ); END;',
trunc(next_day(SYSDATE,'SUNDAY'))+11/24,
'TRUNC (SYSDATE+7)+11/24');
COMMIT;
DBMS_OUTPUT.put_line('Job: ' || l_job);
END;
/
DBMS_JOB
For example; Kill Long Session ( procedure ) with DBMS_SCHEDULER are as follows.
BEGIN
SYS.DBMS_SCHEDULER.CREATE_JOB
(
job_name => 'SYS.KILL_LONG_SESSION'
,start_date => TO_TIMESTAMP_TZ('2020/02/06 16:00:00.000000 +03:00','yyyy/mm/dd hh24:mi:ss.ff tzr')
,repeat_interval => 'FREQ=MINUTELY;INTERVAL=1'
,end_date => TO_TIMESTAMP_TZ('2090/08/18 00:00:00.000000 +03:00','yyyy/mm/dd hh24:mi:ss.ff tzr')
,job_class => 'DEFAULT_JOB_CLASS'
,job_type => 'STORED_PROCEDURE'
,job_action => 'SYS.KILL_LONG_SESSIONS'
,comments => NULL
);
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'RESTARTABLE'
,value => FALSE);
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'LOGGING_LEVEL'
,value => SYS.DBMS_SCHEDULER.LOGGING_OFF);
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE_NULL
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'MAX_FAILURES');
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE_NULL
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'MAX_RUNS');
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'STOP_ON_WINDOW_CLOSE'
,value => FALSE);
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'JOB_PRIORITY'
,value => 3);
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE_NULL
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'SCHEDULE_LIMIT');
SYS.DBMS_SCHEDULER.SET_ATTRIBUTE
( name => 'SYS.KILL_LONG_SESSION'
,attribute => 'AUTO_DROP'
,value => FALSE);
SYS.DBMS_SCHEDULER.ENABLE
(name => 'SYS.KILL_LONG_SESSION');
END;

Monitor or List DBMS_JOB
You can list and monitor the DBMS_JOB as follows.
select * from dba_jobs;
dba_jobs view columns are as follows.

Type ----------------------------------------- -------- ---------------------------- JOB NOT NULL NUMBER LOG_USER NOT NULL VARCHAR2(30) PRIV_USER NOT NULL VARCHAR2(30) SCHEMA_USER NOT NULL VARCHAR2(30) LAST_DATE DATE LAST_SEC VARCHAR2(8) THIS_DATE DATE THIS_SEC VARCHAR2(8) NEXT_DATE NOT NULL DATE NEXT_SEC VARCHAR2(8) TOTAL_TIME NUMBER BROKEN VARCHAR2(1) INTERVAL NOT NULL VARCHAR2(200) FAILURES NUMBER WHAT VARCHAR2(4000) NLS_ENV VARCHAR2(4000) MISC_ENV RAW(32) INSTANCE NUMBER SQL>
DBMS_SCHEDULER Jobs Monitor
You can list and monitor the DBMS_SCHEDULER as follows.
select * from dba_scheduler_jobs;
You can list and view the log of DBMS_SCHEDULER as follows.
select * from DBA_SCHEDULER_JOB_LOG;
dba_scheduler_jobs view columns are as follows.

You can monitor all scheduler jobs run details as follows.
select * from ALL_SCHEDULER_JOB_RUN_DETAILS;
You can monitor dba scheduler running jobs as follows.
select * from dba_scheduler_running_jobs;
