Oct 14, 2010On a huge transaction the buffer cache gets fulled and on that case oracle automatically writes to the data files. And as such when we issue commit statement it does not take more time. It only writes the dirty buffers to the dirty buffers to the datafiles.
When we rollback does the data gets erased from the datafile. What is the mechanism of rolling back ? It should be clearing the dirty buffers for sure.

Server Administration :: Rollback Segment Too Small ORA-01555
Jan 19, 2012One of the users received the error
ora-01555: rollback segment too small
I have read about the error and saw that it is caused by transactions made upon same data, filling to maximum one of the UNDOTBS rollback segments.It happens only once in a while, each time on a different Rollback Segment.
I've read that i should do a few things to enlarge those segments, such as bring a 1. segment offline, 2. drop it and then 3. create it with a bigger size & possibly a bigger extent setting
i've also read that those actions aren't relevant if you have the parameter UNDO_MANAGEMENT set on AUTO, which is actually the case.is that why when i execute ALTER ROLLBACK SEGMENT RB_SEG_NAME_11$ OFFLINE;
1. How do i solve my issue with the Rollback segment being too small to contain the snapshot with the requested SCN?
2. what does the parameter UNDO_MANAGEMENT mean? should i change it, in order to adjust my Rollback Segments attributes, to prevent my error of re-occurring?

PL/SQL :: Use Of Commit Clause
Dec 28, 2012I have this stored procedure and sequences:
create sequence a_seq;
create sequence b_seq maxvalue 26 cycle;
create sequence c_seq maxvalue 1000 cycle;
create or replace
procedure inserta_en_B (numregistros in integer) as
ultimo_año_nuevo date := trunc (sysdate,'year');
dias_transcurridos number(3) := sysdate - ultimo_año_nuevo;
begin
[code]........
First i insert into b 400000 rows using:
execute inserta_en_b(400000));
commit;
But then i need to insert 100000 rows more using the stored procedure and without removing the 400000 rows stored before. I think i need to use the commit clause, but i dont know where.

Implicit Commit While Purging
Oct 24, 2011I have written a purge package that would delete records older than 10 years. Since the data is huge, the purging was taking 14 hours plus. To improve performance, I disabled constraints , deleted records and then reanabled them. This was quite quick but the only problem is rollback. Say for some reason if enabling constraints fails there is no way to rollback as enabling and disabling constraints does an implicit rollback.
View 1 Replies View RelatedSQL & PL/SQL :: Commit In Trigger In Oracle
Aug 3, 2013I 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.
SQL & PL/SQL :: Possible To Commit Changes In Certain Rows Of Certain Tables
Jun 29, 2011I am using the SQL-Developer to access and manipulate a database. I am not very sure about the format of the database (I'm new to databases), but I had to setup the TNS-folder.
Anyway, I guess the problem is the same for any database.
I am having a table with the BOM (bill of material) positions of certain articles and I want to change the BOM quantities of some of the articles. What happens is that I can only change some of the rows. For other rows I get the message like (it is in German, so I try to translate it):
"data was commited in another/the same session already. row cannot be updated"
This error message looks like there is somebody else locked on the database and manipulating it, correct? Is that possible to see somewhere which processes/people are currently accessing to the database?
I saw that there is one process/another database, which is having the authorization to access to the database. But where can I check if this process is accessing to the database?
BTW: I used to do this process before, and it worked. I had been able to manipulate arbitrary entries on the database. I guess that the process or the person, mentioned above, hasn't been accessing to the database at that time.
SQL & PL/SQL :: Not Updating All Records In 1st Commit

View 3 Replies View RelatedForms :: Commit_form Does Not Commit
Dec 18, 2011I am calling a child form from a parent form.It works perfectly if the parent form is adding records and while entering records when i press the button to call the child form, the whole things work perfectly according to plan.
The problem begins when i run execute query command in the parent form and then call child form then it does not "commit_form". So this is my problem that child form does not work perfectly when parent form is being called in execute_query procedure.
My working:
1) I read in the documentation that When parent form status is query_only then child will also have the same mode regardless of the parameter given in call_form.So i checked the :SYSTEM.FORM_STATUS of both the parents and child form,it shows "CHANGED" hence this point is covered. (dont know how come the parent form is in changed status but at least it is doing my work)
2) I further read and found that Commit_form procedure make the :SYSTEM.FORM_STATUS as QUERY. Here i am facing problem as in child form when i make changes and press commit form. Then before commit_form and after commit_form the :SYSTEM.FORM_STATUS results in "CHANGED".You can see this in the following code which i have written in save button.
message(:SYSTEM.CURRENT_FORM || ' a ' ||:SYSTEM.FORM_STATUS); pause;
commit_form;
message(:SYSTEM.CURRENT_FORM || ' b ' ||:SYSTEM.FORM_STATUS); pause;
IF Form_Success THEN
Commit;
IF :System.Form_Status <> 'QUERY' THEN
Message('Error prevented Commit');
RAISE Form_Trigger_Failure;
END IF;
else
message('FAIL');
END IF;
exit_form;
then at last exit_form module shows that" i have unsaved data in the form" save Yes-No-Cancel?

View 4 Replies View RelatedForms :: 10g Win XP 32 Bit - Key-commit Trigger?
Oct 10, 2013I 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.
