Hi,
I am an Oracle developer and new to SqlServer. Is there rollback
segment in SqlServer? If there is, does it use only for the purpose
of rollback or to maintain read consistency as well?
If there is no rbs in SqlServer. How does it handle rollback and read
consistency?
Thanks!
Susan
Hi everyone,
I'm new to SQL Server, but have worked a lot with oracle. I'm not sure if some of the terms I'll use is specific to oracle or if SQL server DBAs also use it. Please bear with me.
I was wondering if I could change the default temporary database or file group (sql equivalent to oracle's default temporary tablespace)for a user.
I also would like to change the rollback segment for a transaction. In oracle it would be: set transaction use rollback segment 'seg_name'.
My sql server version is 2000 by the way.
I would be very greatful if anyone could help.
Hi,
I´m trying to transfer a large amount of data from Oracle 8 to Sql Server. For each table, I have an OleDBSource with DataAccessMode Command (select with one inner join), Data Conversion and OleDBDestination. Sometimes I´m getting an ORA-01555 snapshot too old error, so I´d like to set a bigger rollback segment, but don´t know how. Please, can anybody help me?
Thanks

I am getting this error in SQL 6.5:
Error: [Microsoft][ODBC SQL Server Driver][SQL Server]. Can’t allocate space for object ‘Syslogs’ in database ‘ER’ because the ‘logsegment’ is full. If you ran out of space in Syslogs, dump the transaction log. Otherwise, use ALTER DATABASE or sp_extendsegment to increase the size of the segment.
Should I increase the size? Its already 350 MB. I would like to start over with a new transaction log. Can I do this?
Hi all,
I encountered error 1105 (Can`t allocate space for object .....) while running a query.
I had dump transaction with no log sucessfully and retry running my query but
still encounter error 1105.
I had checked my database size and following are the info:
Datasize : 2500MB Database size available : 753.39
Log space : 500MB Log space available : 500MB (this was acheive after
after dump trans. twice. it was around 480MB before)
Thus looks like the data segment is full!!!
I expanded the size of the disk device D on which the segment device A is on by 50MB. When I did a sp_helpdevice D, the expansion is reflected.
Next I run sp_extendsegement, A, D.
However running sp_helpsegment A doesn`t show that segment A is expanded.
Please help!!! How do I expand the size of the segment? (without creating a new disk device, is it possible)
Any other way to resolve this problem?
Also how to check if a particular segment is full? eg. the %usage of data/log segment.
Thanks in advance.
I am trying to increase the performance of a small database with a table
that occupies 60% of the disk space.
Aside from archiving some data , I am thinking of moving the only index now
-- the clustered index -- on to its own segment in an effort to speed up
performance. I am sure if:
1) a clustered index can be on a separate segment since the data, I think,
would move with it? Is hat correct?
2) If it is corect, should I do that? How ?
Thanks.

Is it possible to run SQL server clustered instance on 2 different IP on two different segment? or two different IP's on the same segment? We are using SQL server 2014 STD and Windows server 2012r2 STD...
View 3 Replies View RelatedHey - this is a SQL 6.5 Question. I get an error that goes something like this...
Can't allocate space for object 'Syslogs' in database 'test_database' because the 'logsegment' segment is full. If you ran out of space in the Syslogs, dump the transaction log. Otherwise, use ALTER DATABASE or sp_extendsegment to increase the size fo the segment.
Okay, i understand that the log is full. But since I have been working mainly on SQL 7, I don't completely understand the 'dumping'. I know that everyone is busy, and if you don't have time to explain this to me, could you tell me where to look? I am going to check MS Knowledge Base, but any advice or direction is appreciated.
Thanks guys and gals!!!

Hi,
Can I rollback a database if I have transaction logs?
For example, I want to rollback the database without all the transactions that occurs within the last 10 days.
Thank you.
I tried killing a rollback several times, but it would not disapear.
I came back the next day, it is still there.
Anyone knows how to get rid of a rollback?
Thanks in advance.
Hi:
I have rollback on one of the users. I tried killing
her process through Enterprise Manager and Query Analyzer,
but I still can see her process on the screen. However, her
login is grayed out after I execute the kill query.
I have encountered this problem several times, and the only way
I can get clear the rollback is by rebooting the server.
Does anyone have a sugeestion on how to clear the rollback
without rebooting.
Please advise if you have any suggestion.
Thanks in advance.
Hi All
A question on DTS ROLLBACK CAPABILITY.
Is it possible to setup a DTS pkg to roll back the loaded files if a step fails?
If a step fail records inserted by Data Pump to a table should be removed.
Is this possible? If so how can we achieve this?
Any advice is appreciated.
Thanks

hi friends,
is it possible to roll back a transaction here? i heard that it will be possible only if we wrote the code only in certain block.please tell me the block.
vinod
The code inserts into table TABLES. TABLES has a primary key.
If the insert statement has no error it should insert 'ROWS INSERTED' to table CONTROL and update table DATETRACKING else insert 'ROWS NOT INSERTED' to table CONTROL and do not update table DATETRACKING.
1- I will like to improve my code if it is possible.
2- Can I use a rollback?
DECLARE @ROWCOUNT INT
DECLARE @ERROR INT
DECLARE @LASTDT DATETIME
SET @LASTDT =GETDATE()
BEGIN TRAN
insert tables
select 4
SELECT @ROWCOUNT = @@ROWCOUNT, @ERROR = @@ERROR
IF (@ERROR <> 0)
BEGIN
INSERT CONTROL
SELECT 'ROWS NOT INSERTED', @ROWCOUNT
END
ELSE
BEGIN
INSERT CONTROL
SELECT 'ROWS INSERTED', @ROWCOUNT
END
COMMIT TRAN
IF (@ROWCOUNT > 0)
BEGIN
UPDATE DATETRACKING
SET LASTDATEDL = GETDATE()
END

Hi!
I just made a transaction which writes and reads some data from a database as one unit. Now, I would like to know, what happens, if this transaction does not commit, but instead performs a rollback? Should I use a boolean loop which keeps on trying the transaction until it commits or is there an alternative? I would appreciate any suggestions or help!
Thanks!
Timothy
I keep getting timeout expired when trying to rollback a transaction (have not tried to commit yet). The script hangs for around 30 secs, then fails.
Now, i've seen there's a command timeout for sqlcommands which defaults to 30 secs, but cannot find anything similar for sqltransaction...
Anyone can help?
Thanks. -julio
Hello:
I am just starting to falmiliarize myself with SQL transactions... I just created an SQL transaction... The first statement gets a value, if the value equals "" then the second statement executes... So if the value <> "" Then the second statement wont execute... What would happen in this scenario if the .Rollback is triggered? Heres my code:
Try
conSqlConnect.Open()
objTransaction = conSqlConnect.BeginTransaction
cmdSelect.Transaction = objTransaction
cmdInsert.Transaction = objTransaction
dtrdatareader = cmdSelect.ExecuteReader()
While dtrdatareader.Read()
varCheckNumber1 = dtrdatareader("Status")
End While
dtrdatareader.Close()
If varCheckNumber1 = "" Then
cmdInsert.ExecuteNonQuery()
End If
objTransaction.Commit
Catch
objTransaction.RollBack
Return "00"
Finally
If conSQLConnect.State = ConnectionState.Open Then
conSqlConnect.Close()
End If
End Try
Any Ideas?
Hello list,
I've some problem in SQL Server 7.0 and hope some one out there will help me with it. The problem is as follows:
When I view a proces in the process info screen, I see one process says "Rollback" in the status window and the spid is greyed out like a system process. In the command window it says, Select and wait type is "Exchange". This is taking too much cpu cycles and causing much of the server to perform very slow.
I tried to kill this session from the ISQL and Enterprise manager, But to still see this process running on with out getting killed. Also this process keeps coming.
Please advice me how to get rid of this and why is it ocurring again and again.
Thanks in advance.

I am getting an automatic rollback in a transaction that fails to insert a row, via a trigger, due to a duplicate key. The transaction is automatically rolled back and unless the error correctly handled a 'partial update' occurs. Why in the example below is the transaction automatically rolled back (statements 1 to 3) and is there any way of knowing what errors generate an auto rollback. For example if the duplicate key error occurs on the insert into table B below, and not the triggered update, then no auto rollback occurs.
Begin Tran -- 1
insert into A values ('A1') -- 2 updates OK
insert into B values ('B1') -- 3 updates OK
-- triggers insert into B_Hist -- 4 Fails with Duplicate Key error
insert into C values ('C1') -- 5 updates OK
Commit Tran -- 6 3902 error No corresponding Begin
Thanks.
Hi,
I have this weird situation on one of the production database.
Somebody ran a sql script couple days ago and must have hit cancelled. Somehow this script is still rolling back. The script is actually very simple statement..should not take more than couple miliseconds to run. Is there any way to see whether rollback is really in process or this process has simply hung? is there any other way to get rid of this rollback without stopping and restarting sql server services? Can it cause problems in getting sql server up again if I restart sql server services?
This may sound a little silly, but does anyone have any words of wisdom on how to optimize a server/database for minimim rollback? We have some multimillion row tables we were trying to do updates against, and after several days they increased the size of the transaction log to the point they filled up the drive the database files/logs were on. We've now been running a rollback for about five days. I'd like to make sure this doesn't happen again.
View 1 Replies View RelatedHi,
what will happen in the following occasion?
checkpoint --> begin tran --> system failure
In MOC (SQL 7.0 Implemetation), it says there will be rollback, but in my humbel opinion, there should be nothing happened.
I think there was no dirty writing in this case. No data pages written, no log
pages written to disk. Am I right? Then, there might be nothing happened
instead of ROLLBACK.
If I am wrong, would you please let me know what is wrong in my thougt?
Thanks in advance,
