Executing A Job Using DBMS_SCHEDULER Inside A Trigger
Oct 10, 2013
I would like to execute an external batch file in Windows using DBMS_SCHEDULER in an Oracle database (10g or a higher version). I intend this to be done through a trigger, which would be called on encountering specific errors in Oracle.
The problem is that I can't create triggers on SYS objects, but DBMS_SCHEDULER is owned by (and as far as I understand, supposed to be used with) SYS user. what permissions need to be granted to which user? Also, can this be done on creating a new user and not using the default SYS and SYSTEM users?
I have to write a script to do the following requirement. There is a file called BUSINESS_DATE.TXT. This file get updated once the oracle partition created. In Oracle, artition will be created every day. There is a seperate script scheduled to take care ORACLE partition creation. The above file will have only one row. i.e. 03092012
If Oracle partition creation job failed, the above file won't be updated. My requirement is, I have to check whether the BUSINESS_DATE file is updated today or not. If yes, I will have to move the files from common area to input file directory to process those files. All file name will amend with current date. i.e .
LIDDIFD03092012.TXT
The key part is to check the BUSINESS_DATE.TXT file is updated properly or not. We don't know what time the file will get updated. So we are planning to schedule the new script to run for every 15 mins to check whether the file is updated or not
But...I just thought instead of writing a shell script to do the above one, Why shouldn't I capture the date in a table (New table needs to be created) and use ORACLE TRIGGER to run the shell script to move the files from common area to input file directory to process those files?
Once the oracle partition created , one row will be inserted into the above table. This adjustment needs to be implemented partition script. Once this table get record, TRIGGER should call SHELL SCRIPT to move the files from common area to input area.
If I implement ORACLE TRIGGER, The script which will check whether the file got updated or not for 15 mins is not required.
I am trying to call procedure inside trigger.. but i get error ora-04098 ..
create table emp_hstry as select * from emp where 1= 2 ;
create or replace procedure emp_del_hstry(v_empno NUMBER , v_ename VARCHAR2, v_job VARCHAR2) is insert into emp_hstry (empno,ename,job) values (v_empno,v_ename,v_job); COMMIT; end;
create or replace trigger emp_del_hstry1 after insert or delete on emp for each row begin if deleting then emp_del_hstry(:old.empno,:old.ename,:old.job); end if; end;
delete from emp where empno = '7369'
AFTER delete statement run i get ora-04098 message i also check show error command ,but still i am not getting solution of this error ..
i would like to create a sequence inside a dml trigger. Is it possible? I created a trigger and it is compiled sucessfully.
create or replace trigger tri_update_test after delete on test declare pragma autonomous_transaction; begin execute immediate 'create sequence t_unqid start with 1 increment by 1 nocache '
end ;trigger created successfully. And i try to delete data from the test delete from test where id=5;
Output:
ERROR at line 1: ORA-01031: insufficient privileges ORA-06512: at "SCOTT.TRI_UPDATE_TEST", line 4 ORA-04088: error during execution of trigger 'SCOTT.TRI_UPDATE_TEST'
1. It should always start with 401 (I can handle that with Oracle check constraint that mypo should be > 401) 2. For each Id, the first insert has to be 401, then it should add one from there within the Id
(something like, mypo is a sequence within the ID.)
I am trying to populate mypo inside the trigger in this way:
CREATE OR REPLACE TRIGGER trigTBL_LTEST BEFORE INSERT OR UPDATE ON TBL_LTEST REFERENCING NEW AS NEW OLD AS OLD
Step# 2 manipulated the tables: Inserted 3 records in Table_C.
Then I created an Insert Trigger to Table_A with an insert statement into Table_B and a subquery to Table_C. Please see below:
CREATE OR REPLACE TRIGGER TABLE_A_TR after INSERT OR UPDATE OR DELETE ON TABLE_A FOR EACH ROW DECLARE [code]......
Step# 3 compiled the created trigger and I've successfully compiled it. Step# 4 Tested the trigger (TABLE_A_TR) using an insert statement to TABLE_A. Insert into TABLE_A values (1,'testa','testb')
I've successfully insert the values into TABLE_A however I've observed that the trigger didn't execute the insert statement because TABLE_B has an empty rows. I tried to manually execute the insert statement just to see if there's an issue in my insert statement but I've successfully populated the values into TABLE_B. So I'm wondering why the trigger didn't execute the insert statement.
Am trying to use the SYS_CONTEXT variables inside a trigger. After reading the documentation I found that the below query when used inside the trigger code will return the trigger owner.
Select Username from User_Users
Will any of the below variables return the trigger owner when used inside the trigger code
sys_context('USERENV','CURRENT_USER') or sys_context('USER','CURRENT_SCHEMA')

I have one problem in trigger execution. I have a small plsql block in trigger and, I want to execute it as a dynamic way. but it is giving the error. Please find the trigger code. Here my intension is that, the column name used in trigger should be dynamic. In future, if I want to switch the column name, I have to do without modification in trigger. The error im getting is "ORA-01008: not all variables bound".
CREATE OR REPLACE TRIGGER ETM_AR_IU AFTER UPDATE ON EXTERNAL_MAPPING REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW
I am trying to schedule a job using DBMS_SCHEDULER.
The job has to start on SATURDAY 12:00 midnight and should run every on SATURDAY 12:00 midnight.
Even if I create the job on MONDAY first it should start on coming sunday and following sundays.
But I am getting the below error.
ORA-27452: BEGIN APPS_GLOBAL.POPULATE_TARGET144('APPS_XX','APPS_BE',5959); end; is an invalid name for a database object. ORA-06512: at "SYS.DBMS_ISCHED", line 124 ORA-06512: at "SYS.DBMS_SCHEDULER", line 271 ORA-06512: at line 2
I have executed two jobs using dbms_scheduler. The value of the job_queue_process is 10 in my database. It is RAC database with Oracle 10g.
My job gets executed. But the next run is not getting executed at the next run date. In the below example, the systimestamp is 12:27. The first job's next run date is 12:30 so that is fine. But the second job's run date is 12:21 which is 6 mintues less than current time. As a result, the second job does not get executed after this at all..
During the daylight savings time our scheduler jobs are running either an hour before/after depending upon the time switch.
I went through the Oracle documentation and found below suggestions which I have already tried in vain.
Document says scheduler first picks the timezone from the start date of the job if provided so i tried setting the start date using the TO_TIMESTAMP_TZ('2012/01/22 18:50:00 US/Eastern','yyyy/mm/dd hh24:mi:ss tzr') which did not fix the problem. I have noticed that oracle automatically converted into tzh:tzm format.
second solution: setting default timezone of scheduler to the TZR i.e (US/Eastern) instead of the TZh:TZM value. I did that using below script
BEGIN DBMS_SCHEDULER.set_scheduler_attribute ( attribute => 'default_timezone', value => 'US/Eastern'); END;
above 2 solutions did not work for me. I have read on internet from some article that below query should return something like
"4/23/2012 11:02:13 US/Eastern" after setting the default timezone of scheduler to TZR but I am still getting "4/23/2012 11:02:13.715816000 AM -04:00". select dbms_scheduler.stime from dual;
I have create a schedule using dbms_scheduler and the problem is its not running on exact time that is start time , i even changed the attribute as following but its not.Its running using dbms_scheduler.run_job(veh_insp) when run directly.The schedule is as follows.
BEGIN DBMS_SCHEDULER.SET_ATTRIBUTE( name => 'INTERVAL_DAILY_2000', attribute => 'start_date', value => TRUNC(SYSDATE)+9.50/24); END;
I have created a job using DBMS_SCHEDULER and I want it to run every 30 seconds:
begin dbms_scheduler.create_job(job_name => 'jobu', job_type => 'PLSQL_BLOCK',
[Code]....
My question is how can I take the value 30 from a configuration table? Let's say I have a query like select value from config_table where property = 'job_interval' that returns the number 30. How can I set this value to be the repeat interval for my job?
We use AIX 6.1 and 10.2.0.4.0 - 64bit. When we create an Job it will be execute as OS User Oracle, but this is not wanted.The file permisions are set as described in Guide to External Jobs on 10g with dbms_scheduler e.g. scripts,batch files
I am facing issues with DBMS_SCHEDULER..I am receiving error while executing the "DBMS_SCHEDULER.run_job"..The OS folder has full permission.
OS : UNix Database: 10g ==================================================================== Error Received:

I am using the client system to change the setting and the time zone differs from that of production. Even though the job is scheduled to run at 5 AM it show the start date as 6:30 PM which is the client system time.
I call dbms_scheduler.run_job('myjob') when i have to run the job. It runs the job and does my action. But if i query select * from user_scheduler_jobs;
last_start_date and last_run_duration column values are null. I want to know how long my job runs to perform the action.
I have a procedure that has a number of "optional" parameters.
procedure get_files( file_name_in in varchar2 default 'dummy_file', layout_in in number default 1, client_in in number default null, data_supplier_in in number default 99999 );
This procedure can be called with any combination of the input parameters.I can set up program(s) using the DBMS_SCHEDULER.CREATE_PROGRAM procedure using a program_type => 'PLSQL_BLOCK' like this:
begin sys.dbms_scheduler.create_program( program_name => 'GET_MY_FILES', program_action => ' declare begin get_files( layout_in => 11111, client_in => 2222 ); end ;', program_type => 'PLSQL_BLOCK', number_of_arguments => 0); end;
My question is: Can I set up programs(s) using the DBMS_SCHEDULER.CREATE_PROGRAM procedure using a program_type => 'STORED_PROCEDURE' when I have "optional" parameters? It appears that ALL of the program input parameters must be defined and there is no way to indicate that a parameters is "optional".
Recently we come across DBMS_SCHEDULER issue while passing SYSDATE as default value. Job executed with corect date value on creation time, but further schedule its not incrementing date value.
I could execute a package for eg if i had a package with procedures related to statistics and i run them each night, could i just do an exec on the package and it would run all those procedures??
Its not possible but i could call each procedure from ONE procedure
