Distributed Database Unique Index Creation
Nov 14, 2007Can anyone suggest an appropriate strategy to create unique index's when a distributed database is used. As a bit of a background I have several SQL Server 2005 servers scattered around the country and I am trying to come up with a way to create a unique index i.e. one that hasn't been used in a particular table say Staff in any of the databases around the country.
Performance is an issue particularly as our network isn't that fantastic has anyone done something similar and achieved reasonable speeds?
Thanks ...
Can I : Set Up A Distributed Database System By Sql Server 2005 Express?
Oct 24, 2007 Hi, I am zeronet. I decide to set up our own web system application just like Ebay. Because of the low investment, I want to select a free DB for our data storage. For high performance, we want to set up a distributed db system. As a beginner of SQL server 2005 express, we want to know: if the SQL-server-2005-express has that ability to manage large amout data and to do with this work? I am eager to hear of your advice.
Thanks.

The Microsoft Distributed Transaction Coordinator (MS DTC) Has Cancelled The Distributed Transaction.
Feb 29, 2008We have a test db, a staging db and a live db. I have a stored procedure that runs fine on test and staging, but throws the following error on live.
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
The stored procedure uses linked servers and a transaction.
We're using the following transaction code in the stored procedure
BEGIN
BEGIN TRANSACTION
BEGIN TRY
---
procedure stuff here
---
COMMIT TRANSACTION
END TRY
BEGIN CATCH
DECLARE @ErrorSeverity INT, @ErrorNumber INT, @ErrorMessage NVARCHAR(4000), @ErrorState INT
SET @ErrorSeverity = ERROR_SEVERITY()
SET @ErrorNumber = ERROR_NUMBER()
SET @ErrorMessage = ERROR_MESSAGE()
SET @ErrorState = ERROR_STATE()
IF @ErrorState = 0
SET @ErrorState = 1
RAISERROR ('ERROR OCCURED:%d', @ErrorSeverity, @ErrorState, @ErrorNumber)
IF XACT_STATE() < 0
ROLLBACK TRANSACTION
END CATCH
END
I found the following link which seems to be the problem we're experiencinghttp://support.microsoft.com/kb/937517
The link includes a workaround which is the following:
"To prevent the SQLNCLI provider from sending an attention signal to the server, use the SQLNCLI provider to consume fully any rowsets that the OLE DB consumer creates. "
How do I use the SQLNCLI provider to fully consume any rowsets?

Mar 28, 2001Hi Folks,
Is there anyway of running a Store Procedure in Database A that's going against database B? I have a store procedure that does a select on table A in database A and a select on table B in database B.
The problem is that the user have exec rights to the store procedure, which is an object in database A. The store procedure won't run because of permission rights to table B in database B.
Is there anyway of queryiny table B without giving the user select rights to that table? Anyone out there had the same problem?
thank you

Distributed Transactions
May 24, 2001Hi to everyone!
Any experience handling a Store Procedure that has distribution transactions?
Here is a story.
We have a store procedure #1 that inserts or updates data in two tables A and B on SQL Server 7.0 then it calls another store procedure #2 that:
1. updates C table in the same database on SQL Server from Oracle Server
2. deletes that record on Oracle Server
3. inserts a record on Oracle from table A
4. inserts the same record into table D on SQL Server from Oracle Server.
People who wrote store procedure #1 put Commit Tran before executing #2.
The questions are:
1. Is it correct that we don't have Commit Tran for #2?
2. What do you think about Nested Begin - Commit Tran?
Any help is highly appreciated.

Oct 3, 2001I have a ODBC data source setup for the AS400DB2 which is AS400JDE
The linked server has been created and all the tables are visible within enterprise manager.
If I had a table F0101, datasource = AS400JDE and linked server of AS400
How would I query it.
I gave tried AS400.AS400JDE.DBO.F0101, but i get the following error message.
OLE DB provider 'MSDASQL' does not contain table '"as400jde"."dbo"."f0101"'.

Jan 20, 2000i added a linked sql 7 production server to my sql 7 development server so i could perform some data comparisons between the two
servers. after i linked in the server, i was able to see all the icons for the various tables in the production server. i went to query
analyzer and executed the following openquery:
select * from openquery(itdev_s08, 'select * from dbo.tablename')
it returned all the rows in the table. however, i want to comapre several different values so i needed a better way to query.
i then decided to try the distrbuted query below:
select * from linkedserver.dbname.dbo.tablename
however instead of a result set i got the error message below:
Server: Msg 7314, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' does not contain table '"dbname"."dbo"."tablename"'.
i went to BOL and it told me the only reason i would get this error is if the object did not exist or if i did not have permission
to use it. however, i know the object exists and i have the appropriate permission becuase i can obtain a result set from the
first query in the same query analyzer window. is my syntax incorrect? what am i doing wrong?
thanks!

Feb 4, 2004Hi,
I am trying to execute a proc on Linked Server. Now as the Linked server name starts with 2, all of the following fails...
Any help to make it work highly appreciated...

exec "2Kxyz.SQLJobMon.dbo.usp_SQLAlertSMTPEmail"
Distributed Transactions
Aug 3, 1998Does SQL Server actually support distributed transactions over, say, two tables in different databases but that reside on the same server? When I try to execute such a transaction in which one part of the transaction violates referential integrity and hence should not be executed, causing the rest of the transaction to, supposedly, rollback, the transaction does not roll back but instead produces an error message and executes the second, valid half of the transaction anyway.
Any help or suggestions gratefully accepted.

following is the error...

Distributed Sp Problem 32 && 64 Bit.
Oct 19, 2006Hey,
I have a Sql 2000 w/ SP4 on Server 2003 running an sp that inserts and updates to a 2005 64 bit DB w SP 1 on Server 2003. The SP has worked forever. No code or server changes. Now all of the sudden I randomly get this error. It will work, then fail 2Xs, then work, then fail. Very bazaar.
Any help is appreciated! I have done the MSDTS, ran catalog sps, forced TCP/IP. I'm lost.
If I run the sp on the 64bit box it works fine, but on the 32bit box now, I get the frequent error below.
[OLE/DB provider returned message: Unspecified error]
Msg 8525, Level 16, State 1, Procedure sp_xxx_xxx_xxx, Line 1496
Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
The line number in the error will change as well and is not always consistent.
Thank you!!!!
Distributed Databases?
Jun 27, 2007Hi everybody.
I have a question about the database performance.
Suppose we have 15 tables distributed to 3 databases. So if we want to to load some related data from diffrent tables of diffrent databases, we have to make more connections to the other databases, and it takes some time to establish the connection. but if we use 1 database with 15 tables, then we wont have this problem and we wont make more connections. but using 1 database, will grow the size of database file (*.mdf) and sure this couses to take more time of file operation like record-seek-time, record-insertion-time and etc.
which of these solutions have better performance? Distributed databases or single one?
Thanks

Distributed Transactions ?
Mar 27, 2006Hi There
I realize this is probably a basic question or at least i hope so but i cannot get distributed transactions working.
BOL is just driving me in circles.
I am running SS2000, MSDTC is up and running on the server.
I have added a trigger to a table where on insert or update the triggers fires and inserts a row to a remote server.
When i execute the update or insert i get the error:
Cannot start a distributed transaction.
I have tried stating BEGIN DISTRIBUTED TRANSACTION before the update but i get the same error, i have also read up on SET REMOTE_PROC_TRANSACTIONS, but this is not a remote sp.
Can anyone please reccomend a good link as to how to get distributed transactions to work.
Thanx
Distributed ETL Server
Mar 8, 2007I work in the data warehouse team of my organization. We are currently rearchitecting our server environment. One of the ideas on the table is to devote a separate server for ETL processing. The databases would reside on several other servers. The ETL server would run the SSIS packages. I'm questioning if this would be a good idea.
The database servers would continue to carry the load of the query processing for the ETL. But with the ETL process on a separate server, the resultsets would need to go over the network for the SSIS package to then work on them. Plus, they would then have to go back over the wire to the destination server.
Are there advantages to this setup? Does this setup have better scalability? Or, would it be better to run the ETL from either the source or destination database server?
Thanks for your consideration.
Ad Hoc Distributed Queries Error
Aug 30, 2006I am getting the following error when with SQL Express.SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online. While I was very please to see such a verbose error and directions on where to find the answer I have yet to figure out how to turn this option on... I tried sp_configure 'Ad Hoc Distributed Queries', 1 but got the following error The configuration option 'Ad Hoc Distributed Queries' does not exist, or it may be an advanced option.If I execute only sp_configure it does not list Ad Hoc Distributied Queries as an option. I checked the sql Books Online and it tells me to use the Surface configuration tool which SQL Express does not seem to have.... Could someone help me out with this?Thanks - Mark

Dec 12, 2001I am using SQL server 7.0 and i have created oracle8i linked server(Using MSDAORA as provider) in it.
When i run distributed queries between SQl server and Oracle server it works fine.But when i try to run distributed transaction between two servers ( BEGIN DISTRIBUTED TRANSACTION..)it reports an error saying Distributed transactions are not supported by MSDAORA.
My question is; is it possible to run distributed transaction between SQL server and oracle server (where oracle server is a linked server in my SQL server)?
Actually i want to run this transaction in DTS package which updates and transfers data amongst various servers.
Thanx

Distributed Queries And Like Operator
Nov 24, 1999Hi,
I am trying to use linked servers (all SQLServer 6.5 and 7.0). When I issue a distributed query utilizing the four-part qualified table name for the distributed machine and using the LIKE operator, the execution plan shows that the remote query is returning ALL the rows from the remote distributed server, then performing the LIKE filter locally on my server! Needless to say, performance sux!
Any ideas what I may be doing wrong or what settings I am unaware of?
Example query:
select * from server.database.schema.table where column1 like 'A%'
Thanx in advance for any help.

Subquery Within A Distributed Query.. HELP!!
Mar 20, 2003I did not get any reply for my previous post. So i am just trying to make my doubt clear.
I have a subquery within a distributed query.
Eg:
SELECT T1.deptID
FROM SERVER1.ACCOUNT.DBO.DEPT as T1
where deptid IN (SELECT T2.DEPTID
FROM SERVER2.DEPARTMENT.DBO.DEPT as T2
WHERE T1.DIVISIONID = T2.DIVISIONID)
In the above query.. T1.DIVISIONID is not recognoized and it says
T1 is not a table or alias name though I have declared it upfront.
You have to note that both the ACCOUNT and the DEPARTMENT database are on different servers.
If they are on the same servers, this should not be a problem at all. Also, all the security is working perfectly for running a distributed query for me.
What is the means to make this subquery work.
Thanks for any help

Distributed Query Issue
Oct 9, 2003SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=W:MyExcel.xls', 'select * from [Sheet1$]')
which works on my local server with Microsoft office XP Professional installed
But keep on failing on the QA server which has MDAC installed only, no Microsoft Office installed
The error msg is 7399. I thought it's because of permission issue.
But problem still resides after I move the Excel file into that QA NT server and execute the statement with a service account which has sysadmin permission on both NT Server and SQL Server
What might be te reason?Why it's working perfectly in my Local server.

This is the error message:

I tried a few of the fixes recommended on the microsoft website but they did not solve the problem. We are still using the same O/S (Windows 2000 Pro), so the only thing that has changed is the server.
Any help would be appreciated.
