Oracle Trigger On Transaction Commit
Nov 29, 2007
I am working with an oracle table that is populated by a trigger on another table.. So Table A is an audit of table B. The trigger also uses sysdate to populate a modification Date column on the Audit table.
I was using this modification Date column in a query interface to get changes that happened on the main table after a certain date/time.
The problem is that there is an application that uses transactions to write to table B and sometime this transaction may not be committed for over a minute so the modification Date is not a reliable way to query the table for changes after a certain time.
Is there a way to update the trigger/create a new one where the sysdate that gets written to the audit table is from when the transaction is committed, not when the transaction starts?

I am using commit in a trigger as given :
create or replace
trigger comt after insert on tbl_city
declare
pragma autonomous_transaction;
begin
commit;
dbms_output.put_line('Value is committed');
end;
Now when I perform an insert in tbl_city---->trigger fires properly and gives output stream. But If I perform rollback now --->there are the data rollbacked in table.
why?I think after commit(which is in trigger associated at insert to table)there should no any rollback in table.

I hv a situation where a webservice interacts with the database.
Here the webservice will first make a request to database for some operation but i dont want the database to commit changes in first request itself. A response will be sent to webservice further a second request will be sent to database for committing the changes. So can that be done?

Query in format Query@DB_Link is sometimes dropping transactions. Move it to a package on target dababase "B" called from DATABASE "A" via package.procedure(varaibles);
Is that all I need to do to get the transaction to always go? I tried a commit in the package body, with repeated attempts if it fails. Btu when I use commit, the package doesn't work. (Compiles fine) Why would the commit fail?
My goal is to make that the transaction succeeds.Code for what I tried below. the COMMIT is commented out - if I uncomment it, the transaction fails. I have done this before calling an oracle SP from SQLServer and it worked
Comments:
The loop is to avoid an endless cycle..The concept is to perform the update, commit it, if the commit fails, rollback and try again.I'm not sure if I even need a loop, but I don't know if the unresolved transaction would get fixed by the remote DB, or dropped.
PROCEDURE BTC_UpdatePart
(
vPart_ID varchar2,
vEngineering_Mstr varchar2,
vCommodity_code varchar2,
vDef_orig_country varchar2,
vDescription varchar2,
[code]...

I have a problem with key-commit trigger. I have written some validations and computations criteria on the block level (lines level). Actually there are a number of loops involved in it.
Problem is that the computations are performed twice. (may be the validations would also be performed twice, which couldn't be felt ). Since i read somewhere that key-commit is fired on different events, which i infered to be firing only just before database commit.

I searched, found this one hit and according to mateoc15, you cannot commit within a procedure that is called from a trigger. He must be right, because mine is not committing either, nor are any errors given.
Trigger
Create or replace trigger owner_name.table1_trg2
after update on table1
for each row
call owner_name.procedure1;
procedure Code (psuedo):
Create or replace procedure1 as
begin
update table1 set col1 = 'whatever';
commit;
exception when others then
rollback;
Executing the procedure as owner_name on SQLPlus works fine, but when I update a column of the table via the PL/SQL package (on the web form), the column does not update, telling me that the procedure never fired from the trigger.

i create this trigger to lock inserting transaction for any data greater than 30-04-2013 on a certain table
CREATE OR REPLACE TRIGGER INVALID_DATE_VALUE BEFORE INSERT or UPDATE on ra_cust
FOR EACH ROW
BEGIN
IF :NEW.TRX_DATE >'30-APR-2013'
THEN
-- RAISE_APPLICATION_ERROR('ora-0000','DATE CANNOT FALL IN RANGE...Invalid Date');
RAISE_APPLICATION_ERROR(-20000, 'IT IS NOT ALLOWED TO INSET DATE VALUE GREATER THEN ''30-04-2013''');
END IF;
END;
and this trigger created successfully
when i try to insert data in the table ra_cust even in a range less than 30-apr-2013
i got this error
ORA-20000: IT IS NOT ALLOWED TO INSET DATE VALUE GREATER THEN '30-04-2013'
ORA-06512: at "ARASK_HAGAR.INVALID_DATE_VALUE", line 5
ORA-04088: error during execution of trigger 'ARASK_HAGAR.INVALID_DATE_VALUE'

Consider a situation:
There are two users 'A' and 'B'
account number of A: 001234
account number of B: 002678
Suppose, if A wants to transfer $1500 to B's account
update cust_acc
set balance = balance - 1500
where
account_no = '001234';
[code]....
Assume that, oracle crashes somewhere between first commit and second commit.In this case, A's total money is deducted by $1500..But $1500 is not yet transferred to B's account.How will oracle keep track of these information?

How can we see the history of transactions on a table.
For eg, If I have a table called TEST123, I would like to know whatever SQLs fired on that table on today.

I have read almost all docs about distributed transaction on tahihi.oracle.com website,But I can find a statment about this:
Can Oracle always guarrantee the data consistent in a distributed transaction?
For example,there is a distributed transaction on node a,node b and nod c.node b and node c informed node a they were prepared,so node a committed,and inform node b and node c commit.then node b committed and feedback,but network on node c broken at this point,So node a can't not get feedback from node c,but node a and node b has been committed, so what will Oracle do in this condition?
If node c rollback the data on local node, consistent in this distributed transaction was failed ,yes?

Having PL/SQL procedure and calling sys dba procedure to alter rollback segment to online and after that to set the transaction to this rollback. The rollback altered to online but transaction still running on available rollback and not the one I was meant to. The user have executing grant on the sys dba procedure.

I am using SQL*Plus to run this Oracle10g. Here is my problem I have to solve: After a new record is added to the task table, write a trigger that reports the new project balance to the user while updating the customer balance to reflect this additional task cost. Insert a new record to show the trigger works. I somewhat understand triggers,I think I have to combine tables to solve this. Here are my tables/attributes I can use to solve it:
CREATE TABLE customer
(
custnoNUMBER(3)CONSTRAINT ccustpk NOT NULL PRIMARY KEY,
custname CHAR(20) CONSTRAINT ccustnamenn NOT NULL,
phone CHAR(12),
curr_balance NUMBER(9,2) CONSTRAINT ccustbalancenn NOT NULL
[code]...

application was not starting due to some pending transaction in database.Pending transactions were rolled back by DBA team.To avoid such situations what I thought was, having a job that will call a procedure that will monitor table status everyday and will send the mail. Now that job is working fine for no pending transactions in DBA_PENDING_TRANSACTIONS.
But now I am in doubt if someday there are PENDING TRANSACTIONs in the table DBA_PENDING_TRANSACTIONS, will SELECT * FROM DBA_ PENDING_ TRANSACTIONs query will work as normal or this whole process of monitoring table and sending mail will work fine?

If I do select distinct(client_id) from pf_stock_txns then I get back a unqiue list of all clients.
However, I need a query that will give me the first transaction for every unqiue client.

I am trying to create some PL/SQL that will create a trigger for UPDATES and INSERTS which will update a column on the same row to the system date.
So far I have:
DECLARE
tablename VARCHAR(30) := 'table';
triggername VARCHAR(30) := 'mytrigger_' || tablename;
[Code]....
I have declared the tablename and triggername outside the trigger creation as I need this to be parameterised for a list of tables.
The procedure IsCDCUser just checks it should be updating for this user.
The problem I get is the following error:
Bind Variable "NEW" is NOT DECLARED

I am writing a after trigger for one of my tables on every insert update and delete for my dataware house staging area. The process here is when ever there is a change in the production database we need to capture this change in our changing area through triggers.
I am able to create the triggers but i am stuck with the exception handling portion of the trigger. I want to write an exception in the trigger where when the staging area is locked or for any other matter the data needs to be able to go to a error table when the staging area is not able to accept the data for some reason.
how i can write this excepyion in the trigger or anyother method i can follow to be able to handle this scenerio.

I have an update trigger that runs a package when fired. I only want this package to run if it is NOT fired from an Oracle Forms application. Ie. A user might update table ABC from an Oracle Form. In this instance the trigger would fire, but I don't want to run the package within the trigger. If the user logs onto PL/SQL developer and updates the table, the trigger would fire and the package must run.
I was thinking of using the field 'program' from v$session. If it is null (it's being fired from an Oracle Forms application) if it has a value (it's coming from SQL*Plus / Pl/sql Developer).

I must create an INSERT trigger, on an Oracle table, which will do an insert into my MS-SQL 2000 DB table.
The tables are exactly the same in this case and I desire to insert the entire row that was just insterted into the Oracle table into the MS-SQL table.
I understand how to create an ODBC connection between the DB servers, I just can't seem to understand the trigger syntax.

I have a job which runs the procedure below concurrently in 4 different sessions; It updates two tables.
PROCEDURE UPDATE_TAB_1_AND_TAB_2( traceIdTab IN pl_sql table,
individualIdTab IN pl_sql table,
fileSeqIdTab IN pl_sql table,
[Code].....
Each session is passed a sequence generated file ID; so the records processed in each session are completely different.
However, everytime this job runs, without failure, ONLY TWO sessions process concurrently, while the other two sessions are blocked. Once the first two have finished, then the remaining two sessions start work.
I have being monitoring the sessions on each run daily, and realized that the first two sessions processing are each holding a transaction exclusive lock on objects; hence blocking the other two sessions.
When I tried to find the objects that the two running sessions have a lock on, I cant seem to find anything by searching DBA_OBJECTS.object_id. However, when I look for the objects that are being waited on, its either a partitioned table or a partitioned index on either table_1 or table_2.
At first, I thought it was an ITL lock and after much analysis, I did not find anything which definitely pointed to an ITL lock. However, just to make sure, I increased the INITTRANS value from 2 to 5, but the problem did not go away.
At this point, I have applied all I know to understand the origin of the TX lock and how I can work around this situation, and decided to ask higher powers in Oracle for advise.
