How sql server will mirror big transaction ?
Example
inserting 10000000 rows in 1 transaction (columns big ,text data ...)
will it transfer data in multiple packets (size, location of temp file) to mirror ?
will it transfer data in 1 packet (size , location of temp file ) to mirror ?
Can you control transfer (size , location of temp file) ?
Thanks

Today, I became an involuntary DBA until my company finds someone else. We have an SQL R2 DB that is mirrored that failed dur to the transaction log growing and filling up the disk. As a band aid remedy, I was able to add 20GB to the disk (it is a VM) and then I backed up the Transaction log and did select log_reuse_wait_desc from sys.databases where name = 'mydb' and the result showed that the backup was successful (NOTHING, I think was the result).
After this I was able to resume the mirror and everything has been running fine. What I need to do now is to shrink the Transaction log so that if it starts to grow again, I will get an alert and can avoid today's issue. From what I have read, I can just use DBCC SHRINKFILE [logname] after I do a backup and the changes will be reflected on the mirror as well. I have shrunk the T-log in non-mirrored servers before, just don't know if there are any key differences.
hi,
i want to create a disaster recovery site, to which i can fail over (not automatically),
and also to have the option to return the database to a point in time?
for example,
if my principal server fails in 17:00,
i want to have the option to make the mirror server available for users from 17:00 (or at least close to that time),
and also to be able the return to the data from 16:00 (in the mirror site).
Is it possible, and what is the best way to do it?
Thanks.
Hi,
I'm trying to add a new transaction log file to a database with mirroring (high safety, automatic failover).
When I add the new transaction log file via SQL management studio, the mirroring status becomes suspended. When I try to restart mirroring, it attempts to re-synchronize and then goes back to the suspended state. Only after I delete the new transaction log file can I sucessfully restart mirroring.
Can you add a transaction log file to a mirrored database? Any ideas would be appreciated.
Also, I'm not sure if this matters, but I am trying this in my development environment and all 3 instances (principal, mirror, witness) are on the same server. It's a long shot, but I thought maybe both the mirror and principal are trying to create the file at the same location on disk.
Thanks,
Don
We have a SQL server 2012 database with size 200mb and Transaction Log has gone up to 34GB.
We have SQL server Mirror is enabled and principal database is running with Full Recovery Model.
How can I truncate/Shrink Log files? Will it impact on existing mirroring setup? I am very much new to SQL server.
When Create Mirror Database Server, Where need to store the Transaction Log backup file?I took FULL Backup of my Primary Database, and I restored at my Mirror Server also. When I try to create a Mirror Database."The remote copy of database "<db_name>" has not been rolled forward to a point in time that is encompassed in the local copy of the database log. (Microsoft SQL Server, Error:1412)".I am misplacing the Transaction Log backup file. Where I need to store that file?

Server A = primary SQL DBs (mirroring origination)
Server B = failover SQL DBs (mirroring destination)
For database mirroring a witness is required.
Can the witness live in another instance of SQL on server B?
Using SQL Server 2008, we would like propose mirroring between two servers of a critical database. Since we initiate, may require to clarify on its purpose and also required changes from application end.Any changes required from OS Level? (I believe both servers IP or Host name should be added in host entries. Mirroring ports should be allowed/open including Principal and mirror server IP Addresses): Windows Team.Any changes required from Application? (Instance name, authentication: user name and its password should be added in web config files): Application Team.Any changes required from Network Team?Also for mirroring both the principal and mirror servers should be with same version, does it only mean SQL Server 2008 versions are enough or does it also mean to say build numbers 10.00.4000 should also be same.URL....

Hi All
I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.

I have a design a SSIS Package for ETL Process. In my package i have to read the data from the tables and then insert into the another table of same structure.
for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.

I want to list out the pending transaction for transaction replication by publication.
Help needed.
I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
Anyone know of the reason?
I created a Calculated measure in cube something like this : ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]). To get only spend transactions. Now, I want to slice this measure with same hierarchy to find the amount distribution across different transaction types under spend transaction. But this query behaving like the measure doesn't have relation with measure.
you can think this as below query:
WITH
MEMBER SPEND AS ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount])
SELECT NON EMPTY {SPEND} ON 0
,NON EMPTY ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent]) ON 1
FROM [CUBE]
Hi
How do I make use of begin transaction and commit transaction in SSIS.
As am not able to commit changes due to certain update commands I want to explicitly write begin and commit statements. but when i make use of begin and commit in OLEDB commnad stage it throws an error as follows:
Hresult:0x80004005
descriptionyntax error or access violation.
its definately not an syntax error as i executed it in sql server. also when i use it in execute sql task out side the dataflow container it doesnt throw any error but still this task doesnt serve my purpose of saving/ commiting update chanages in the database.
Thanks,
Prashant

Hi,
I am having some problem with SSIS transaction. Eventhought I tried to imitate the concept that Jamie presented at http://www.sqlservercentral.com/columnists/jthomson/transactionsinsqlserver2005integrationservices.asp
. My workflow is as followed
*********************************
For Each ADO.Record in Oracle (transaction=not supported)
If (Certain_Field_Value = 'A')
Lookup Data in SQL DB with values from Oracle (transaction=not supported)
DO Sequence A (Start a Transaction , transaction=required)
INSERT/UPDATE some records in SQLDB(transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'B')
Lookup Data in SQL DB with values from Oracle (transaction=not supported)
DO Sequence B (Start a Transaction , transaction = required)
INSERT/UPDATE some records in SQLDB (transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'C')
------------
------------
End ForEach Loop
*************************************
My requirements are that I want separate transaction for each Sequence A, B, C, etc... If Sequence A transaction fails, the other should still be continuing with another transaction.
But I am getting an error regarding the OLEDB Error in next Task (e.g in Certain_Field_Value = 'B') "Lookup Data in SQL DB with values from Oracle ", the error message is ".......Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction. ".
What is it that I am doing wrong?

Hi all,
In my ASP application, I've been using this code:
----------------------------------------------
dim conn, connectionstring
connectionstring= "Provider=SQLOLEDB.1; Data Source = blahblah; Initial Catalog = abc; User Id = osss; Password=xxx"
set conn = server.CreateObject("adodb.connection")
conn.open connectionstring
----------------------------------------------
It's just basically to set up the connection to the SQL server, it works on my other pages, but on a few pages, the last line (conn.open connectionstring) triggers this error:
"Microsoft OLE DB Provider for SQL Server error '8004d00a'
New transaction cannot enlist in the specified transaction coordinator. "
I've never encountered this error before and I couldn't think of any solution... please help!!!
Thanks so much,
Annie
I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)
For instance, run these statements to set up a test:
--DROP TABLE testTable1
--DROP TABLE testTable2
CREATE TABLE testTable1 (f1 varchar(1))
CREATE TABLE testTable2 (f1 varchar(1))
CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1)
insert into testTable1(f1) values ('a')
So table testTable1 has a unique index on it..
Now try to run these statements:
--DELETE FROM testTable2
BEGIN TRANSACTION
insert into testTable1(f1) values ('a')
insert into testTable2(f1) values ('a')
COMMIT TRANSACTION
SELECT * FROM testTable2
..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?
Hi,On My local SQL server I have added a linked server to another SQLserver (remoteserver) in another Windows NT Domain.When I run this codeselect count(*) from remoteserver.mosaics.dbo.LocationThis works fine.However when I usebegin transactionselect count(*) from remoteserver.mosaics.dbo.LocationIt errors out saying thatThe operation could not be performed because the OLE DB provider'SQLOLEDB' was unable to begin a distributed transaction.New transaction cannot enlist in the specified transactioncoordinator. ]OLE DB error trace [OLE/DB Provider 'SQLOLEDB'ITransactionJoin::JoinTransaction returned 0x8004d00a].My question is even though I am just reading data from theremoteserver, why does the local transaction get promoted to adistributed transaction.Any help will be grately appreciated.TIA...Rohit

Is there someone who can help me ? This is the process 1. In C# --> Call of a Query : select from the linked server (db in sql 2005) and insert into a table SQL 2005 2. In the C# --> using (TransactionScope scope = new TransactionScope()) and insert in a table in SQL 2005 which is link server Thank in advance.

By mirroring I mean device mirror, since I do not think that there is a database mirror
We only have disk mirror. I also know that SQLServer 7.0 does not provide Mirror, unmirror or remirror. and for this we have to refer to Windows NT disk mirroring.
I need mirroring in both versions SQL Server 6.5 and 7.0
I want to have mirror on another server. I need this for tonight.
Sincerely.
I hereby let u know the steps that i undertook for performing mirroring
1. Created a database in Principal server named Mirror1 and one table named tblMirror1.( no values inside the table)
2. Repeated the same in Mirror in Witness
3. Selected the Principal server's database -->right click-->tasks-->mirror
4. from the left hand panel selected Options -->recovery model-->full
5. selected Mirroring from left hand panel-->configure secuirty-->entered mirror and witness name--Success
6. When I click on start mirroring I have an error stating
" Alter failed for database mirror1"
"Database mirroring cannot be enabled because Mirror1 database may have bulk logged changes that have not been backed up etc...."
7. followed this one
BACKUP database mirror1 TO DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'
got the answer as
Processed 160 pages for database 'mirror1', file 'Mirror1' on file 2.
Processed 1 pages for database 'mirror1', file 'Mirror1_log' on file 2.
BACKUP DATABASE successfully processed 161 pages in 0.318 seconds (4.147 MB/sec).
According to sources
Run a restore of this backup on your mirror.
This can be done through the GUI or using a T-SQL command.
The database restore must use the NO RECOVERY option, so the database stays in a loading state.
Also the database name on the mirror must be the exact same name as the principal
RESTORE TestMirror FROM DISK='C:Backup TestMirror_FULL.BAK' WITH NORECOVERY
Hence did the below
RESTORE database mirror1 FROM DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK' WITH NORECOVERY
ERROR
Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'. Operating system error 2(The system cannot find the file specified.).
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
HENCE MODIFIED AS
use master
go
RESTORE database mirror1 FROM DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK' WITH NORECOVERY
Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'. Operating system error 2(The system cannot find the file specified.).

hello
if i run dbcc dbreindex on a database thats the principal in a mirrored pair, will the mirrored database indexes also be rebuilt?
i am for the first time creating the database mirroring.I am moving the all the usr databases and everything from test server to a new server called test1.And from that new server i am restoring on the another new server called test2 for database mirroring.But in the test server , the transaction logs are backup for every 15 minutes.So in this case is there a need to move all the logs to test1 and then to test2 for mirroring?? or there is no need to move transaction logs to the new servers at all??
my secnario
------------
server1 server2 server3
-------- ------- --------
test test1 (moving everything from test) test2(mirror for test1 )
all the transaction logs are backup in test for every 15 minutes. so in this case , do i need to move the transcation logs from test to test1 and test2
or there is not need to move at all??
thanks,
