I have below oracle job.
dbms_scheduler.create_job
(job_name => m_job_name,
job_type => 'PLSQL_BLOCK',
job_action => 'begin Pkg_Shell.PR_WF_PROC('
|| p_seq_request
|| '); end;',
number_of_arguments => 0,
start_date => sysdate,
repeat_interval => null,
end_date => null,
job_class => 'DEFAULT_JOB_CLASS',
enabled => false,
auto_drop => true,
comments => null
);
The above job is not dropping automatically. This job will run only once. When i went thru various sites it says
For auto drop,This flag if TRUE, causes a job to be automatically dropped after it has completed or has been automatically disabled. A job is considered completed if:
1.Its end date (or the end date of the job schedule) has passed.
2.It has run max_runs number of times. max_runs must be set with SET_ATTRIBUTE.
3.It is not a repeating job and has run once.
My job will run only once. Why my job is not Auto dropped in certain scenarios. ? We couldnt find when it is not dropped. To over come this
If i want to mention end_date like sysdate + 2 hours how to mention it ?
If i want to set max_runs or max_fails how to use that in my job. ? Whether these two settings or anyone above will solve my problem ?
After so long i found the below links that helped me to fix my issue. I have used max_runs set to 1 .
dbms_scheduler.set_attribute(m_job_name,'max_runs',1);

I have a question regarding the Oracle Jobs.
If I have a Job defined to be executed every 5s, but if for any reason there is a Job that last 6s. What will be the consequences ?
for instance:
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'oe.my_job1',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN DBMS_STATS.GATHER_TABLE_STATS(''oe'',
''sales''); END;',
start_date => '15-JUL-08 1.00.00AM US/Pacific',
repeat_interval => 'FREQ=SECONDLY;INTERVAL=5',
end_date => '15-SEP-08 1.00.00AM US/Pacific',
enabled => TRUE,
comments => 'Gather table statistics');
END;

i) 2 Jobs executing at the same time ???
ii) A job FIFO queue ??
Is there a way to tell the job to be executed only if no job of the same action is running at that moment ????
from the docs:
https://docs.oracle.com/cd/B28359_01/server.111/b28310/scheduse004.htm#ADMIN10040
Immediately after a job is started, the repeat_interval is evaluated to determine the next scheduled execution time of the job. It is possible that the next scheduled execution time arrives while the job is still running. A new instance of the job, however, will not be started until the current one completes.
I want to create oracle scheduler job which runs daily at 20:00 and runs for 30 minute. This job will delete the rows from KPI_LOGS table as this table contains large amount of data and it continues to grow. I have created the below script in oracle sql developer for such job but not sure if this is correct or not as i am new to scheduler job concept.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => '"RATOR_MONITORING"."CROP_KPI_LOGS"',
job_type => 'PLSQL_BLOCK',
job_action => 'DELETE FROM KPI_LOGS WHERE CAST(TIMESTAMP AS DATE) < (SYSDATE - 28);',
number_of_arguments => 0,
start_date => NULL,
repeat_interval => 'FREQ=DAILY;INTERVAL=30',
end_date => NULL,
enabled => FALSE,
auto_drop => FALSE,
comments => 'CROP_KPI_LOGS');
DBMS_SCHEDULER.SET_ATTRIBUTE(
name => '"RATOR_MONITORING"."CROP_KPI_LOGS"',
attribute => 'logging_level', value => DBMS_SCHEDULER.LOGGING_OFF);
DBMS_SCHEDULER.enable(
name => '"RATOR_MONITORING"."CROP_KPI_LOGS"');
END;
the repeat_internal is incorrect, what you have there will run every 30 days. to run at 8pm each day go for...
FREQ=DAILY; BYHOUR=20
you can't dictate how long it will run for, it will take as long as your DELETE statement takes
Hi i have to show one report and the report data should refresh on every monday.
automatically
I have checked oracle scheduler . i cant see any option for limiting the interval to monday
.
I am thinking to give start date as monday and repeat 7 days interval .
is it good way
Hi I got the answer.
YOU want to right like the code below.
There are 3 way for scheduling a job on every week day it can be every monday or another day
Here i have tried for running the job automatically on every monday 6 am
We have to set the frequency
either of the below code we can use
FREQ=DAILY; BYDAY=MON; BYHOUR=6; BYMINUTE=0; BYSECOND=0;
FREQ=WEEKLY; BYDAY=MON; BYHOUR=6; BYMINUTE=0; BYSECOND=0;
FREQ=YEARLY; BYDAY=MON; BYHOUR=6; BYMINUTE=0; BYSECOND=0;
begin
dbms_scheduler.create_job(
job_name => 'JOB_TEST',
job_type => 'PLSQL_BLOCK',
job_action => 'begin PROCEDURE_NAME; end;',
start_date => systimestamp,
end_date => null,
comments => 'job is created for running automatically on every monday',
enabled => true,
repeat_interval => 'FREQ=WEEKLY; BYDAY=MON; BYHOUR=0; BYMINUTE=0; BYSECOND=0;');
end;
In oracle We can write jobs using DBMS Scheduler or DBMS JOBS
DBMS Scheduler is the above example and its the advanced one,
IF you want to Do the same Problem Using DMBS JOBS
begin
sys.dbms_job.submit(job => :job,
what => 'procedure name;',
next_date => NEXT_DAY(TRUNC(SYSDATE),'MONDAY'),
interval => 'NEXT_DAY(TRUNC(SYSDATE),''MONDAY'')');
commit;
end;

I have been trying to schedule the refresh of three materialized views simultaneously every night. I have used the below code
BEGIN
DBMS_SCHEDULER.CREATE_JOB
(
JOB_NAME => 'REFRESH_MVIEW',
JOB_TYPE => 'PLSQL_BLOCK',
JOB_ACTION => 'BEGIN DBMS_MVIEW.REFRESH("m_view1, m_view2, m_view3",''C''); END;',
NUMBER_OF_ARGUMENTS => 0,
START_DATE => SYSTIMESTAMP,
REPEAT_INTERVAL => 'FREQ=DAILY; BYHOUR=0',
END_DATE => NULL,
ENABLED => TRUE,
AUTO_DROP => FALSE,
COMMENTS => 'JOB TO REFRESH'
);
END;
But I am getting the following error after the job has been run
ORA-12012: error on auto execute of job 57179
ORA-06550: line ORA-06550: line 1, column 495:
PLS-00114: identifier 'm_view1, m_view2' too long
, column :
I understand that there is a constraint of 30 chars in the procedure name. So, does that mean I have to split the job into 3 different jobs? Could you please let me know where I am going wrong?
Thanks in Advance !
Could you please let me know where I am going wrong?
Try to write your statement like that instead:
BEGIN DBMS_MVIEW.REFRESH(''m_view1,m_view2,m_view3'',''C'')
Or
BEGIN DBMS_MVIEW.REFRESH(''m_view1,m_view2,m_view3'',''CCC'')
View list is specified using a string -- so using single quotes. I don't know if spaces are relevant in the view list. In doubt, I've removed them too.
Please note in the first case you have a default refresh for later two views. If you need a complete refresh for all your views, you have to specify CCC as the refresh method.

I want make JOBS use DBMS_SCHEDULER in oracle 10g, where jobs refresh minutely with interval 2 minute running everyday start at 08.00 AM and end at 08.00 PM. I have tried this code,
BEGIN
SYS.DBMS_SCHEDULER.CREATE_JOB
(
job_name => 'UPDATE_REKAP_BALI'
,start_date => trunc(sysdate) + 8/24
,repeat_interval => 'freq=MINUTELY;interval=2'
,end_date => trunc(sysdate) + 20/24
,job_class => 'DEFAULT_JOB_CLASS'
,job_type => 'STORED_PROCEDURE'
,job_action => 'UPDATEREKAPBALI'
,comments => NULL
);
END
but, when i check on the next day, the jobs is not running, i guess that the jobs is never running up again on 08.00 AM at the next day.
Make sure you commit after submitting the job.
Edit This is incorrect: DBMS_SCHEDULER performs an implicit commit, unlike the previous DBMS_JOB which required an explicit commit.
You have to make auto_drop to false , because auto drop will make the job to be dropped once after it is running , so make it as false
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'TEST_J',
job_type => 'CHAIN',
job_action => 'TEST_C',
auto_drop => FALSE,
repeat_interval => 'FREQ=DAILY;BYHOUR=08,09,10,11,12,13,14,15,16,17,18,19;BYMINUTE=02,04,06,08,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,00;BYSECOND=00;',
enabled => TRUE);
END;

Auto Drop is enabled by default
