I would like rename scheduler job in Oracle, is it possible?
dba_scheduler_jobs(owner = "db", name = "my_job")
=> dba_scheduler_jobs(owner = "db", name = "my_own_job");
Thanks for answers.
A job is a database object, so the RENAME command works natively
SQL> begin
2 dbms_scheduler.create_job (
3 job_name => 'MY_BAD_NAME',
4 job_type => 'PLSQL_BLOCK',
5 job_action => 'begin null; end;',
6 start_date => systimestamp,
7 repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
8 enabled => true);
9 end;

SQL> rename MY_BAD_NAME to BETTER_NAME;
Table renamed.
SQL> select job_name from user_scheduler_jobs;
JOB_NAME
--------------------------------------------------------------------------------
BETTER_NAME
Instead of rename, you can create/replicate job and drop the old one.
Below, my_new_job1 has created.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'my_new_job1',
program_name => 'my_saved_program',
repeat_interval => 'FREQ=DAILY;BYHOUR=12',
comments => 'Daily at noon');
END;
/
Below, my_new_job2 has created with same details as my_new_job1
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'my_new_job2',
program_name => 'my_saved_program',
repeat_interval => 'FREQ=DAILY;BYHOUR=12',
comments => 'Daily at noon');
END;
/
Below an old job my_new_job1 has been deleted.
BEGIN
DBMS_SCHEDULER.DROP_JOB ('my_new_job1');
END;

I have created an oracle job using dbms scheduler.But the status gets failed in the execution. It gives the following error. 'ORA-27367: program "Schema.PROG_SIXMONTHPRIORITY" associated with this job is disabled' But I do not have disabled the job. 'program_action => 'SIXMONTHPRIORITY'' is a procedure that I have created in the schema. When I execute that procedure separately, it gets executed.
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
program_name => 'PROG_SIXMONTHPRIORITY',
program_action => 'SIXMONTHPRIORITY',
program_type => 'STORED_PROCEDURE');
END;
BEGIN
DBMS_SCHEDULER.CREATE_SCHEDULE (
schedule_name => 'P_SCHEDULE_3',
start_date => SYSTIMESTAMP,
repeat_interval => 'FREQ= MINUTELY; INTERVAL=30; BYMONTHDAY=19; BYHOUR=13',
end_date => SYSTIMESTAMP + INTERVAL '1' day,
comments => 'Every 30 minutes');
END;
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'CAL_SIX_MON_PRIORITY_3',
program_name => 'PROG_SIXMONTHPRIORITY',
schedule_name => 'P_SCHEDULE_3');
END;
Can anyone identify the reason for this error?
The Scheduler objects that you created can also be separately enabled or disabled. Make sure to specify "enabled => true" when creating scheduler objects:
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
program_name => 'PROG_SIXMONTHPRIORITY',
program_action => 'SIXMONTHPRIORITY',
program_type => 'STORED_PROCEDURE',
enabled => true);
END;
BEGIN
DBMS_SCHEDULER.CREATE_SCHEDULE (
schedule_name => 'P_SCHEDULE_3',
start_date => SYSTIMESTAMP,
repeat_interval => 'FREQ= MINUTELY; INTERVAL=30; BYMONTHDAY=19; BYHOUR=13',
end_date => SYSTIMESTAMP + INTERVAL '1' day,
comments => 'Every 30 minutes');
END;
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'CAL_SIX_MON_PRIORITY_3',
program_name => 'PROG_SIXMONTHPRIORITY',
schedule_name => 'P_SCHEDULE_3',
enabled => true);
END;
For existing objects, you can set the attributes directly:
BEGIN
DBMS_SCHEDULER.ENABLE ('PROG_SIXMONTHPRIORITY');
DBMS_SCHEDULER.ENABLE ('CAL_SIX_MON_PRIORITY_3');
END;

I have an API package written. It has the GET_INFO procedure. I want this procedure to be performed in the background every 20 minutes. I understand what I should do with dbms_scheduler. But in general I do not understand where to register them . I will be grateful for the example or for your help with this)
I wrote such a code but I don't know where to use it:
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name = 'My_Job',
job_type = 'STORED_PROCEDURE',
job_action = 'INSERT INTO TEST2(UPDATEDAT)
VALUES (sysdate);
END;',
start_date = 'systimestamp',
repeat_interval = 'FREQ=SECONDLY;INTERVAL=5',
end_date = null,
auto_drop = FALSE,
comments = 'My new job');
END;
Here is my code and I don't know where to store it.
As the job type implies, you need a procedure to be created such as
create or replace procedure Ins_Test2 is
begin
insert into Test2(updatedat) values(sysdate);
commit;
end;
and then create the scheduler through
begin
dbms_scheduler.create_job (
job_name => 'My_Job',
job_type => 'STORED_PROCEDURE',
job_action => 'Ins_Test2',
start_date => systimestamp,
repeat_interval => 'freq=minutely; interval = 20; byday=MON,TUE,WED,THU,FRI;',
enabled => true,
comments => 'My new job'
);
end;
where I added
byday=MON,TUE,WED,THU,FRI; as an extra direction if you want to run
the scheduler within the working days(you can omit that part if you'd
like).
systimestamp(get rid of quotes) for start_date might be
replaced with an upcoming time info such as start_date => '13-FEB-20 2.00.00PM Asia/Istanbul'
in my case.
And follow by listing the created schedulers by
select job_name, next_run_date
from dba_scheduler_jobs j;
And currently running ones by
select *
from user_scheduler_job_log l
order by l.log_date desc;
And drop the scheduler by
begin
dbms_scheduler.drop_job( job_name => 'My_Job' );
end;
I have to create a job periodically.
But firstly I have create a simply job to learn how to create jobs in oracle, because is the first time I use a job.
It runs at systimestamp, but the job doesn't execute.
create or replace procedure job_test
is
begin
update table_a set value_user = 'JOB_EXECUTED' where id = 1;
commit;
end;
/
Then the scheduler job
begin
dbms_scheduler.create_job(
job_name => 'test_job_A',
job_type => 'stored_procedure',
job_action => 'job_test',
start_date = SYSTIMESTAMP,
enabled => true
);
end;
/
Then I consult the column value_user and it hasn't been updated.
select * from table_A where id = 1;
Can anyone explain me what I am missing.
create table user_count (
number_of_users NUMBER(4),
time_of_day TIMESTAMP
);
CREATE OR REPLACE PROCEDURE insert_user_count AS
v_user_count NUMBER(4);
BEGIN
SELECT count(*)
INTO v_user_count
FROM v$session
WHERE username IS NOT NULL;
INSERT INTO user_count
VALUES (v_user_count, systimestamp);
commit;
END insert_user_count;
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
program_name => 'PROG_INSERT_USER_COUNT',
program_action => 'INSERT_USER_COUNT',
program_type => 'STORED_PROCEDURE');
END;
BEGIN
DBMS_SCHEDULER.CREATE_SCHEDULE (
schedule_name => 'my_weekend_5min_schedule',
start_date => SYSTIMESTAMP,
repeat_interval => 'FREQ=MINUTELY; INTERVAL=5; BYDAY=SAT,SUN',
end_date => SYSTIMESTAMP + INTERVAL '30' day,
comments => 'Every 5 minutes');
END;
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'my_user_count_job',
program_name => 'prog_insert_user_count',
schedule_name => 'my_weekend_5min_schedule');
END;
exec dbms_scheduler.enable('my_user_count_job’)
select * from user_count;
select job_name, status, run_duration, cpu_used
from USER_SCHEDULER_JOB_RUN_DETAILS
where job_name = ‘MY_USER_COUNT_JOB’;
Indeed your case should work but once(provided there already exists a row with id value equals to 1). Suppose you have an insert statement rather than an update, but doesn't repeat to populate the table with new incremented ID values.
For this, important point is to add repeat_interval argument such as below :
begin
dbms_scheduler.create_job(
job_name => 'test_job_A',
job_type => 'stored_procedure',
job_action => 'job_test',
start_date => SYSTIMESTAMP,
enabled => true,
repeat_interval => 'FREQ=MINUTELY;INTERVAL=5',
auto_drop => false,
comments => 'Inserts new records'
);
end;
/
which inserts new records for each five minutes.
I have an event scheduler in mysql which is executing fine
CREATE event 'STORE' ON schedule every 1 hour doUPDATE c_store
SET is_active = '0'
WHERE web_id =
(
SELECT web_id
FROM c_web
WHERE Datediff(Now( ) , createdon ) > 15)
My query is i want the same in Oracle , can any one guide me.
You need to use DBMS_SCHEDULER to create a job and schedule it to run hourly.
For example,
SQL> BEGIN
2 DBMS_SCHEDULER.DROP_JOB (JOB_NAME => 'test_full_job_definition');
3 END;
4 /
PL/SQL procedure successfully completed.
SQL>
SQL> BEGIN
2 DBMS_SCHEDULER.create_job (
3 job_name => 'test_full_job_definition',
4 job_type => 'PLSQL_BLOCK',
5 job_action => 'BEGIN my_job_procedure; END;',
6 start_date => SYSTIMESTAMP,
7 repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
8 end_date => NULL,
9 enabled => TRUE,
10 comments => 'Job defined entirely by the CREATE JOB procedure.');
11 END;
12 /
PL/SQL procedure successfully completed.
SQL>
SQL> SELECT JOB_NAME, ENABLED FROM DBA_SCHEDULER_JOBS where job_name ='TEST_FULL_JOB_DEFINITION'
2 /
JOB_NAME ENABL

TEST_FULL_JOB_DEFINITION TRUE

You must use DBMS_SCHEDULER
Here you can find some examples.
I've an Oracle job defined as follows:
BEGIN
DBMS_SCHEDULER.drop_job('clean_journal_partitions');
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'clean_journal_partitions',
job_type => 'STORED_PROCEDURE',
job_action => 'CLEAN_JOURNAL_PARTITION',
repeat_interval => 'FREQ=WEEKLY;BYDAY=MON',
auto_drop => FALSE);
DBMS_SCHEDULER.ENABLE('clean_journal_partitions');
END;
That if I'm not wrong, it should be executed once a week every monday. The problem is that it is executed only once and I don't know why.
To be able to test it more easily, I've modified it to change the frequency from weekly to every 10 seconds, like this:
BEGIN
DBMS_SCHEDULER.drop_job('clean_journal_partitions');
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'clean_journal_partitions',
job_type => 'STORED_PROCEDURE',
job_action => 'CLEAN_JOURNAL_PARTITION',
repeat_interval => 'FREQ=SECONDLY;INTERVAL=10',
auto_drop => FALSE);
DBMS_SCHEDULER.ENABLE('clean_journal_partitions');
END;
And I've the same problem. It is executed only once. Any hint why the job is not executed every 10 seconds?
This works fine for me in Oracle 11g:
CREATE TABLE TEST(
run_time DATE
);
CREATE OR REPLACE PROCEDURE CLEAN_JOURNAL_PARTITION AS
BEGIN
INSERT INTO TEST VALUES(SYSDATE);
COMMIT;
END;
/
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'clean_journal_partitions',
job_type => 'STORED_PROCEDURE',
job_action => 'CLEAN_JOURNAL_PARTITION',
repeat_interval => 'FREQ=SECONDLY;INTERVAL=10',
auto_drop => FALSE);
DBMS_SCHEDULER.ENABLE('clean_journal_partitions');
END;
I get one entry in the TEST table every 10 seconds. Your problem must be in your CLEAN_JOURNAL_PARTITION procedure, maybe it crashes?
