Forms :: Post Built-in Commits Changes In The Database?
May 7, 2010
I have been testing out a form using 10.1.2.0.2 on a v10.2.0.1 db and in my local env. the form works correctly i.e. if I make a change and 'post' it and then exit and press NO (when asked to save changes) then it correctly leaves the value in the database as it originally was.
The process works by the user pressing a button in form A (read only form) and this opens form B (using open_mode,session,activate) and the user makes their change(s) in form B (a 'post' command is issued in a When New Rec Inst trigger on a db block when the user navigates to a new record within the same block if it is determined that the block status <> 'QUERY') before returning to form A and pressing 'NO' when prompted to save changes.
However, if I run the same process in the TEST env. using the same executable against the same database then it actually updates the database value.
I have tested this by adding a debug message at the end of form B to retrieve the db value back AFTER having issued a clear_form(no_commit) just for the sake of the test and it still returns me the 'new' i.e. amended value - which is obviously incorrect. From what I can see it would appear that the commit occurs straight after the 'post' has been issued and well before the user even exits the form.
Is this a known bug with the 'post' built-in or could it be that a parameter is set to act in this way (i.e. is there an 'autocommit' setting that is 'ON') within the application server?

I have a form which will call another and do some transactions and come back to original form and do other processes. save if successful. or roll back with error message.i m doing POST when i exit from the called form. and continue process in calling form. if any error, i m raising an error message with rollback.
But sometimes, it is getting committed with that error trn. especially in new database, first time try the scenario, it any error comes then getting commited.I m not able to find where the commit is happening? if any other sessions commit will affect this trn?

I have one form in which there are master detail blocks. I am entering one record in master block and corresponding entry in detail block. If again I am entering a new record in master block, of course the corresponding entry is getting erased since the block is getting changed.
After entering the data in master block I want to pop a message as 'whether you want to duplicate the same entry in detail block '. If yes, then how can I copy the same details which i have entered for previous record? Can I use duplicate_record built in? If yes, How?

Is there anyway to speed up the performance of the go_record built it or is there an alternative way to do it.
I have a table with nearly 30,000 rows and I would like to implement a text field that will allow the user to jump to a specified record. The only problem is if they try to jump too far away it will take a long time to load (beginning to end of 30,000 takes over a minute).
This problem doesn't arise if all the records, or up to the one they are jumping to, have been fetched already, but even if I fetch all records at the beginning it will still take a long time to initially load them.

I have a client who is facing the above error. Everything used to work perfectly but since a week, he gets this error message on a specific FORM. No updates have been made to the FORM.
The FMXs are stored on the database server(10G R3, Windows 2003 R2) and the Client terminals access them through a network drive.When executing the conflicting FORM on the server, no error.
I call the DBMS_ERROR_CODE routine from a FORM-LEVEL ON-ERROR trigger :
DECLARE
ERR NUMBER;
BEGIN
IF DBMS_ERROR_CODE=-1 THEN
MSG('Client existant',ERR,'E');
ELSE
[code]....
Code for procedure MSG :
PROCEDURE MSG(TXT_MSG IN VARCHAR2 , RET_REP OUT NUMBER , TYPE_MSG IN CHAR DEFAULT 'I' ,
LABEL_BUT1 IN VARCHAR2 DEFAULT 'OK' , LABEL_BUT2 IN VARCHAR2 DEFAULT NULL ,
LABEL_BUT3 IN VARCHAR2 DEFAULT NULL) IS
VL_ALERT ALERT;
BEGIN
[code]....

I have an issue with the oracle forms trigger. This is the scenario. The form is a query only form . A user can only query on this form . No update or insert is allowed.
The base table say TABLE1 consists of these fields. 1) pro id, pro item, empno , fname, lname, deptno .
The user can query on all items except the fname and lname.
The issue is few records in the TABLE1 have null values for the empno.
When the user queries on proid, pro item , empno or deptno - when the empno on TABLE1 is not NULL , the fname and lname should be fetched from a different table say TABLE2. otherwise, if the empno on TABLE1 is null , the fname and lname from the same table i.e, TABLE1 are retrieved. I have tried with the post change trigger on empno . Also tried the When validate item trigger . But it doesnt work the way it is expected to. what is the appropriate trigger that must be used.

I have a view t1 having the records:
1 A
1 A+
2 B
3 C
4 D
I want to display that in an LOV but without the first record (1 A) I used the code :
SELECT DISTINCT num,
DECODE(num,1,(SELECT DISTINCT desc FROM t1 a
WHERE a.desc='A+'AND a.num=1),desc) desc
FROM t1
this worked fine but how to apply this in a post_change trigger where a user inters the num and the desc appears in atext-item in my form

I have this layout
[URL]
and a post trigger insert and update
IF :item1 IS NULL
AND :item3 IS NOT NULL THEN
alert_id := FIND_ALERT('blank_alert');
SET_ALERT_PROPERTY(alert_id,ALERT_MESSAGE_TEXT,'Item3 must have a value.');
v_alert := SHOW_ALERT(alert_id);
RAISE Form_trigger_Failure;
END IF;
My problem was as it fires, the cursor will be on the item1. I've already use
SET_ITEM_INSTANCE_PROPERTY
NEXT_ITEM
GO_ITEM
but it was all illegal. The cursor must be in the item3.
Don't question me why I do not set the item3 to required and why post triggers. It is just that. It is the requirement.

We just migrated our technology platform on one of the six servers yesterday on production d/b as follows :
OAS Server - Linux Patch Applied (2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:19 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux)
D/B Server - From Oracle 10.2.0.2.0 to Oracle 10.2.0.4.0
Batch Server - From OpenVMS to Red Hat Linux
Post Migration, we are facing some issues with Oracle Forms 10g, Text Items which contains one or more than one multibyte characters, is displaying only # character in the entire text box instead of what is stored in the database. In other words, information in the database is stored correctly. Before Migration everything was working perfectly fine.
One other thing which I would like to tell here is that we compile forms using the following environment settings:
NLS_LANG_SEMANTICS=CHAR
NLS_LANG=AMERICAN_AMERICA.UTF8

I have a multi record block based on a view. All records in the view are displayed in the block by use of Post-Query trigger when entering the form.
The block has 5 items as follows:
1) RECORD_STATUS = a non-base table column which is a checkbox.
2) ITEM_TYPE = a text-item which has an LOV attached.
3) ITEM_TEXT = a text-item which is free format text.
4) LAST_UPDATE_DATE a date column
5) STATUS = a text item either 'Open' or 'Closed'
The LOV is based on a table of Item Types with values say, 'Type1', upto 'Type9'.
I have a Wnen-New-Record-Instance trigger which 'Posts' changes to the database. This has been included as i want to limit the values of the ITEM_TYPE column to values which have not been previously used.
Consider this scenario...
The block has 3 records.
record 1 has 'Closed' status so no updates are allowed.
record 2 has 'Open' status so updating of Item_Text is allowed.
record 3 has 'Open' status so updating of Item_Text is allowed.
I check the RECORD_STATUS checkbox on record2.
(This sets the RECORD_STATUS checkbox to a checked value and changes the STATUS column to 'Closed' by When-Checkbox-Changed trigger.) At this point the record has not been saved so if you uncheck the checkbox , then the STATUS column will go back to 'Open'. However at this point i will leave it as Checked (Closed).
I then insert a new record, only values Item4 to Item 9 are correctly shown in the LOV. I select Item4.
I then go back to the previous record and uncheck the Checkbox to say that i wish to leave it 'Open' after all (in effect no changes have occurred), then the STATUS column correctly reverts back to 'Open' by my WCC trigger. If i then SAVE the changes, the new record has been inserted on the database correctly, however the LAST_UPDATED_DATE from the record which was checked and then unchecked has also been updated incorrectly even though no net changes have actually occurred.
(because i am using WNRI trigger to limit the List of Values on the LOV column, this has incorrectly set the previous records LAST_UPDATED_DATE column to be Sysdate.)
How can i stop this from happening?

I have a form w/a tab canvas. BlkA is on Tab1 and Blk2 is on Tab2. In BlkA I have several items that have when-validate-item triggers. However, the trigger does not fire when I enter a value into item1 of BlkA followed by clicking on Tab2. To solve, I placed validate(form_scope) in the When-Tab-Page-Changed trigger. This works well with invoking the validation. However, focus remains on Tab2 (Blk2).
I would like focus to return to failed validation item in Blk1. I can capture the block name using :system.cursor_block in the Post-Block trigger of BlkA, assign that value to a form parameter and when a validation fails via the When-Tab-Page-Changed trigger I can return user back to BlkA(Tab1). However, I need direction on how to return user to the specific item in BlkA that failed validation

I'm working on a Java-based web application and we have unit tests that we use to test all our all code that interacts with the database or code that interacts with our DB code. The Spring framework allows us to perform some DML within a transaction before each test and then rollback the changes. For the most part, this works, however when I run the full suite of unit tests, it will randomly commit data to the database causing the rest of the tests to fail.
will Oracle's auditing let me see where this odd-ball commit is occurring? Is there another way for me to see when data is being committed?
This does not appear to be happening on any of the systems we've deployed, however this is a bit unsettling and would like to know why this is occurring so that we can prevent it from happening in production.

When a user session commit he is waiting on 'log file sync' untill LGWR sends the message back to user session after writing log buffer content into redo log file.As far as i understand this is serialize operation(one at a time).
So how come i have 7 ms average 'log file sync' wait time and i can still perform 200 commits per sec ?
7 ms * 200 waits = 1400ms = 1.4 sec

In any application, we will have many commit statements issued in many places. How can we find out as to where all commits have happened during runtime.
Basically in our application, when am trying an operation, am getting the error ORA-01086: savepoint <save point name> never established.
My guess is that there is a commit somewhere because of which system is not able to rollback to that save point.

i tried the following update on one table:
update siebel.s_contact
set marital_stat_cd =
case
when (marital_stat_cd = 'Casado') then 'Married'
when (marital_stat_cd = 'Solteiro') then 'Single'
when (marital_stat_cd = 'Divorciado') then 'Divorced'
end
As you can see i forgot the else, so my update is wrong.
I thought i could rollback the update issuing the rollback statement, but when i have issue the rollback, the i query the table to confirm that the update was rollbacked and for my suprise the update is commited.
I didn�t issue the commit statement after the update and i confirmed that the auto-commit feature to worksheets is disabled, so i don�t understand whit the update was commited.

We have a fact table t1 in the warehouse which has above 6 million records.There is to be an update like this where t2 has aid+bid as composite primary key. column aid repeats in t1.There's performance problem and we'v been told to break this huge update into pieces with few commits in the middle.
update t1
set t1.aid =
(select t2.aid from t2
where t1.bid = t2.bid
)
I've tried cursor loop with 3 commits in the middle based on if condition that evaluates on every iteration.

I would like to write a select that would return all places in DB that are commiting transaction.
E.g. package for testing:
CREATE OR REPLACE PACKAGE test.TEST_COMMIT AS
PROCEDURE THE_ONLY_COMMIT_IN_DB ;
END TEST_COMMIT;--not a match
CREATE OR REPLACE PACKAGE BODY test.TEST_COMMIT AS
[code]....
The select should return 4 rows with --ok.
SELECT *
FROM ALL_SOURCE ASO
WHERE
REGEXP_LIKE(ASO.TEXT,'commit(s*);','i' )
AND name = 'TEST_COMMIT'

This error occurs while trying to print a report in a PDF format using Oracle Application Express 3.0. I'm not sure what this means and how to fix it. I'm running Oracle 10g on Windows Vista.
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1186
ORA-12570: TNS: packet reader failure
This is the first time I'm attempting to print to a PDF. I did follow configuration according to the Oracle documentation. I selected the Standard configuration that uses the built-in Apache FOP or another standard XSL-FO processing engine.
