Distributed SSIS Server Setup
Mar 8, 2007
I work in my organization's warehouse team and we are rearchitecting our hardware. One of the ideas on the table is to devote a server to running ETL. There would be several beefy database servers, and a separate server that would run the ETL (SSIS). I'm wondering if that actually hinders the process.
The DB servers will still do all of the query processing, so that isn't off loaded to the ETL server. Then the recordsets I think would need to go over the network to the ETL server for the SSIS packages to work on. And then another trip over the network back to their destination. Would it be better to place the ETL process on either the source or destination DB server? What could be gained by using hardware in this way as described here?
Thanks.

Hi, I am planning on having an SSIS dedicated server in a new install of SQL 2005. We will be using MSDB to store the packages. But I have a question.
Since we will be using MSDB to store the packages, how should the setup be? Should SQL also be installed on the SSIS server? Or can we use the SQL server (seperated dedicated server) to store the files?
Since SQL Agent is installed with SQL Server, can we use our SQL Server to schedule the packages? Or if using the SQL Server to schedule the packages make the packages run on that server (instead of the SSIS server)?
Basically I am confused on what needs to be installed on the SSIS server (since we will be using MSDB storage) and where the packages should be scheduled (if scheduled on SQL but SSIS is installed on a different server, where will it process??).
Thanks.

Hi,
My name is Vinh, I am a new bee in SQL Server 2005. I am using template script (see below) from SQL Server to create account but when I am right click in database mail for testing email and I got the message, could not connect to mail server.
Below I am trying to use smtp to connect but I know in my company we are using Exchange Mail Server. will that make a lot different?
Please help me,
Thank you very much,

I would like to know best practices for setting up my environment. To date, I've had everything running on a single server. That would include the database engine, SSIS, SSAS and SSRS. The box configuration is dual hyperthreaded 3.6GHz Xenon with 4GB of RAM on Windows Server 2003. I just received a much larger server and want to configure it to maximize our environment. The new box contains four 2.6GHz Quad Core processors with 16GB of RAM. I would like to know if I should split the ETL and database engine from SSAS and SSRS, or should this box have enough horse power to house it all and use my other box as a dev environment. Also, we are planning to purchase Performance Point 2007 primarily for PAS and Scorecard Manager so please take that into consideration as well. Any comments are greatly appreciated.
Thanks.

Hi -
I've seen variations on this question in this forum, but none of the suggestions work for me, so any ideas would be greatly appreciated!
I have a SSIS package whose function is to monitor a directory for flat files and distribute the information in these files into a SQL 2005 DB for further processing later. I've configured Transactions for the package as serializable and supported, and I have a ForEach container set to serializable and required. All SQL and Data Flow tasks take place within this container. I have a single Connection Manager to pull in the flat input file, and another for the connection to the SQL DB. This setup will function, and roll back if necessary, but I take a huge hit on the continual establishment of connections to the DB. If I set the retainsameconnection property on the SQL DB Connection manager, I get an error when executing my first Data Flow task to move data from the flat input file to working tables within the DB: 0xC001A004 - Incompatible transaction context was specified for a retained connection. If I turn off Transaction support, the retainsameconnection property works as expected.
I've been running Profiler Traces, and can verify that no connection has been established to the SQL Server prior to execution of this task, so it seems like the context should be OK. I would welcome any feedback, suggestions or alternatives.
Thanks,
Jim SweeneySLC

I am running a number of SQL instances on my PC. Within the network, I have think server with various System Center components. For compatibility reasons, some features of System Center 2012 R2 had to be delegated to different SQL databases. My question is, because there is now more than one IP address on my system, and each instance of SQL is assigned to its own IP, is there a way to setup DNS and SQL so the namespace points to the desired IP address? For Instance:
MSSQL2008 instance is set to run on = 11.12.13.1
MSSQL2012 is set to run on = 11.12.13.2
IN DNS:
A Record: Mike-PC = 11.12.13.1
A Record: Mike-PC = 11.12.13.2
If I want to use MSSQL2008 by specifying Mike-PC as the DNS name, how would I do that with 100% accuracy? If there is another way to get the job done, I am more than willing to approach this differently.

Is there any use of creating an SSIS Setup project? Since the Package Installation Wizard already does a good job of it?
Which brings up a question - why dont SSIS Packages compile to a dll just like any other .NET project? It seems interpreted from the .dtsx file except for the Script Tasks of Components which are pre-compiled.
Why did MS change the design language all of a sudden?
But please answer - is there any use of creating an SSIS Setup project?

Hi All,
This may be a question for multiple forums but here it goes.
I have a large SSIS package that works great in Visula Studio (BIDS) and in SQL Server under MSDB folder. The properties are all set to save with a sql server authentication package password and that works great too. The problem occurs when I try to use this package in a schedule. I get an error about an OLB DB not working. I've tried many things and figured out that all the OLB DBs do not work in this package but only error as a STEP in a schedule.
They all reference a Client Access ODBC connection - which is a connection to an AS400 IBM machine. The actual error is pasted below, where I guess the root of the problem is a incorrect password. The password is fine and I have proven that by running the package successfully under the MSDB folder of Stored Packages under Integration Service.

We 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 @ErrorState = 1
RAISERROR ('ERROR OCCURED:%d', @ErrorSeverity, @ErrorState, @ErrorNumber)

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?

I would like to setup SSIS project so that multiple developers can work on same project. I am having issues with protectionlevel properties while another developer opens the package created by other developer.
Can anyone guide me on setting up project so that multiple developers could open the package and run (not simaltaneously though). Also tips on setting up source safe or team foundation will be appreciated!

I 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.

I need to deploy some SSIS packages onto a remote Integration Server machine. Hence
I wrote a VS 2005 Setup with Custom Action (C# Installer class) which uses the
SSIS DTSX Dlls to deploy the Packages onto an Integration Server. I am shipping
all the necessary DLLs in the MSI itself, so that the MSI can run on any client
machine having just .NET 2.0 Framework installed.
When I run the Setup on a Machine having Integration Server, the Setup works
fine and the Packages are deployed.
However, if I try to run the MSI on a machine which just has the .NET 2.0
Framework installed, I get the following error.
SqlServer.DTS.Runtime.Application could not be created. Retrieving the COM
class factory for component with CLSID
{E44847F1-FD8C-4251-B5DA-B04BB22E236E} failed due to the following error.
80040154
I am not sure whether any of the DLLS are COM components. I believe all are
Managed DLLs.I believe SSIS 2005 looks like a pre-requisite but I don't need that.
Please help. I am posting this query here, as I believe ppl writing SSIS Packages may have faced this issue.

I receive the following error message when I run a distributed query against a loopback linked server in SQL Server 2005:
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
To resolve this problem, I was told that running a distributed query against a loopback linked server is not supported in SQL Server 2005. And I am suggested to use a remote server definition (sp_addserver) instead of a linked server definition to resolve this problem. (Although this is only a temporary resolution, which will deprecate in Katmai)
However, I run into another problem when I use the remote server definition. I receive the following error message:
Msg 18483, Level 14, State 1, Line 1

A recent SharePoint upgrade has rendered several views obsolete. I am redefining them so that our upper level executive reports show valid data.(yes, I know that doing anything to sharepoint could cause MS to deny support, having said that, this is something I've inherited and need to fix, pronto) The old view was created like so:
USE [AHMC]
GO
/****** Object: View [dbo].[vwSurgicalVolumes] Script Date: 09/04/2015 09:28:03 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [dbo].[vwSurgicalVolumes] AS
SELECT
[code]....
As I said, this view is used in a report showing surgical minutes.SharePoint is now on a new server, which is linked differently (distributed?) I've used OPENQUERY to get my 'new' query to work;
SELECT *
FROM OPENQUERY ([PORTALWEBDB], 'SELECT
--AllLists
AL.tp_ID AS ALtpID
,AL.tp_WebID as altpwebid
,AL.tp_Title AS ALTitle
[code]....
My data (ie surgical minutes, etc) seems to be in the XML column, AUD.tp_ColumnSet . So I need to parse it out and convert it to INT to maintain consistency with the previous view. How do I do this within the context of the view definition?Here is a representation of the new and old view data copied to excel :
<datetime1>2014-08-14T04:00:00</datetime1><float1>2.000000000000000e+000</float1><float2>4.190000000000000e+002</float2><float3>1.600000000000000e+001</float3><float4>8.110000000000000e+002</float4><sql_variant1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sqltypes="http://schemas.microsoft.com/sqlserver/2004/sqltypes"
[Code] ....
can't format it to make it look decent. InHouseCases =2, InHouseMinutes=419, OutPatientCases =16, OutPatientMinutes=1230. This corresponds to the new data I can see in the XML column; 2.000000000000000e+000 is indeed 2 and 4.190000000000000e_002 is indeed 419.

How do I stop a remote query that INSERTS into a local table from being automatically "upgraded" to a distributed transaction?
I am using Windows 2000 server and SQL Server 2000 SP3a on both machines.
I am executing the following statement in Query analyzer.
INSERT MyLocalServer (col1)
EXECUTE MyRemoteServer.Master.dbo.sp_executesql
@RemoteQuery,
@ParameterDefinition,
@Paramter = 'somevalue'
@RemoteQuery consists of a SELECT four-table join, all tables are on the same linked server.
The Linked server has been set up on MyLocalServer using the "Microsoft OLE DB for SQL Server" provider. In the "Provider Options" for the linked server properties I checked "Non transacted updates" and "dynamic parameters". In the "Server Options" tab I have checked "RPC", "RPC Out", "Data Access".
The EXECUTE part of the query runs great (and returns the data very fast) by itself. But with the INSERT part, the query fails and returns the error:
"Server: Msg 7391, Level 16, State 1, Line 17
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a]."
The two servers are seperated by firewalls, so I believe the reason the query is failing is that I haven't followed the procedures for setting up the ports etc described in one of the microsoft support articles: e.g.: 250367.
Configuring the ports involves too much company politics, and besides, for what this query does, it does not need the benefits of a distributed transaction.
How can I execute my query without SQL Server automatically trying to upgrade it to a distributed transaction?
More Info: I can execute the query as a straight INSERT/SELECT linked-server query and it does the INSERT on the local SQL Server just like I want it to, so I assume it is not trying to use distributed transactions; but it takes around 7 seconds to run even though the entire SELECT is executed on the linked server, whereas executing with sp_executesql takes only 1 second.
I thought selected "non-transacted updates" in the provider would solve this problem, but it did not.
Anyone know the answer?

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.
if i'm using the 0 for commandtime out then i'm getting the Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
and
Failed to open a fastload rowset for "[dbo].[P@@#$%$%%%]". Check that the object exists in the database.
Please help me it's very urgent.

My problem is..when i am trying to query on these tables its giving me error saying "OLE DB provider 'MSDASQL' does not contain table xxxxxx"
i am using select * from servername.tablename.dbo.tablename.
Any help on this will be appreciated.

Three weeks ago we began a project that involved importing data from an AIX DB2 6 environment via a linked server configuration. Following the data import a second query was executed against the db2 environment using data that resides in the new table within SQL 7 in the join statement (a very basic example is provided below) This was all accomplished in sequence via a package.
SELECT F_NAME, L_NAME, PASSWD
FROM SQL7.LOCALSRV.dbo.NEWUSERTBL as new, DB2.SYSIBM.MASTERTBL.OLDUESRTBL as old
WHERE new.USER_ID = old.USER_ID
Originally we had no problems and while the execute time was not exactly speedy it was tolerable as we would revisit optimization after we established if what we were trying to accomplish was feasible. At the outset the first data import to build the local table was immeadeate and then the distributed query to retirieve more info to build another local table against the DB2 server took aproxiamtly 1 minute per user row returned. Currently we are looking at still having an immeadeate data import (a matter of seconds to build the first table)but now we are looking at more than 1 hour returned for 1 correesponding row of data off of DB2. We are utilizing the the IBM DB2 ODBC DRIVER.
Any input or suggestions as to what could be causing this or perhaps a more efficeint way to code the statement would be much appreciated. Thanks in advance.

I am working on a linked server where a few of the queries use almost exclusively remote tables from 1 other server. I have read somewhere that there are options to specify where a query is performed but can't find it anywhere. Could someone tell me the command and how to use it or point me to something to read about it.

Can someone please shed some light on what seems to me to be a common requirement.
If I create an alias or linked server to Server1 - say Alias1 - on Server1 and then use that name in a query on Server1, a remote/distributed query is always used (even though we are running on the local server and that overhead is completely unnecessary).
Is SQL Server really not capable of deciding that
select * from Alias1.db1.dbo.table1
and
select * from Server1.db1.dbo.table1
should be optimized and executed exactly the same when Alias1 is Server1, but that it is a distributed query ONLY when Alias1 is really referring to a remote server? I realize that the four part name is not necessary when I am referring to objects on the current server, but I am trying to write code that is server instance independent.
It just seems that if that is not possible, then the only way to create system independent stored procs that can run in dev, staging, and production environments and work with multiple databases on multiple servers is to create all sorts of scripts to regenerate all the procs whenever you move a database between servers?
If SQL Server is even close to the enterprise big iron server that MS now claims it is, it surely needs to support running in dev, staging, and production environments and work with multiple databases on multiple servers?!
I'm really looking for someone to tell me I'm missing something simple, and of course you can do this - but complex workarounds are invited too :-)
This is not something I am investigating as an academic exercise, I am already doing this, but I have to figure out how to do it better because with all these unnecessary distributed queries, performance is horrible.
Thanks

When I run it with a local LAN IP it works fine, but when I use a public ip my analyzer hangs and doesnt give me any output. I am using a dedicated dialup 64kbps connection. I have tried this query without begin distributed trans and commit trans and it worked fine, may be there are extra overheads with transactions, if so let me know
As an alternate I have tried registering server with sp_addlinkedserver and then executing a query with direct server reference, but had the same problem with it.

We are migrating a database that makes use of distributed queries. In other words, it queries data from other databases on the same server, as well as from databases on linked servers.
The use of linked servers as well as linked databases (for lack of a better term) presents a challenge since we will need to register various new linked servers in the target environment. Ideally, we would like the database to be portable such that we will not have to worry about registering linked servers regardless of where it is hosted.
Is there a way to write distributed queries so that do not rely on linked servers/databases? For example:
SELECT * FROM [ServerName].[Database].[Owner].[TableName]
If there is such a method, it would make our database much more portable in terms of server migration.
TIA.

Hi,I'm having a problem running a distributed transaction between twolinked servers that both have multiple instances of SQL Serverinstalled on them. This is the error message that I receive:"The operation could not be performed because the OLE DB provider'SQLOLEDB' was unable to begin a distributed transaction.[OLE/DB provider returned message: New transaction cannot enlist in thespecified transaction coordinator. ]OLE DB error trace [OLE/DB Provider 'SQLOLEDB'ITransactionJoin::JoinTransaction returned 0x8004d00a]."The query follows the format:"BEGIN DISTRIBUTED TRANUPDATE [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAMESET fieldname = alias2.fieldnameFROM tablename alias2JOIN [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAME alias1on alias2.urn=alias1,urn"[color=blue]>From what I can gather from various sources the SQL Server must be[/color]named the same as the computer which it is installed on. However, if Ihave two instances of SQL Server, they cannot both be named the same asthe computer. Does anyone know of a way around this or whether I'mbarking up the wrong tree completely?Many thanks.

I have a database containing my own tables and data and I wanted tobe able to query this against an accountancy program which has an ODBCdriver. This was never a problem with MS Access and Jet but I hit Jet'slimitations and have moved to SQL.Creating my own SQL database was no problem, but I was unsure of thebest way to be able to be able to have my SQL tables and my accountancysoftware tables appearing in the same Access front end.I created a linked server to the accountancy program. This wassuccessful in that I could see all the tables below the linked server inenterprise manager.My problem occurs when I try to bring the data from these tablesinto my SQL database.I create a new view in my database:-SELECT *FROM OPENQUERY(SAGE_SERVER, 'SELECT * FROM STOCK')(My linked server is called 'SAGE_SERVER' and I am trying to retrieveall columns from the STOCK table.)I then try to save this view and get the following errors.ODBC Error: [Microsoft][ODBC SQL Server Driver][SQL Server]The operationcould not be performed because the OLE DB provider 'MSDASQL' was unableto begin a distributed transaction.[Microsoft][ODBC SQL Server Driver][SQL Server]OLE DB Error Trace[OLE/DBProvider 'MSDASQL' ITransactionJoi JoinTransaction returned 0x8004d00a].Thanks in advance,Marcus Thornton.

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.
yours
zeronet

Hi,
The distributed query seems to work on the management studio of the server where I have linked the other server to but not accross the network on other management studio with the same impersonated logins. The error I get is.
OLE DB provider "SQLNCLI" for linked server "usbo-sql01" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18452, Level 14, State 1, Line 0
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

We get the below error while performing a distributed transaction on linked server. We have several linked servers configured in the source server and all of them succeed with the distributed transaction except on one.
We did all the basic troubleshooting and moreover the distributed transactions work fine if we use a remote server instead.
Error:
OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 3
The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" was unable to begin a distributed transaction.
Test code:
begin distributed transaction
select top 10 * from [SERVERNAME.REDMOND.CORP.MICROSOFT.COM].master.sys.objects
ROLLBACK
