Data Source And Connection Manager
Jan 8, 2007
Hi all,
I don't really understand the difference between the "data source" and the "connection manager" in a SSIS solution.
I tried to create a data source (if I understood correctly, I will ba able to share that connection between all packages in the solution), then I create a new connection manager inside a package. But when I make a modification in the data source, nothing change in the connection manager ?!!?
What I think is that when I'm making a new connection manager, what's really happen is a copy of the data source, is that correct ? If it is I dont't understand the avantage of making a new data source ....
Thanks for your response

Hello,
I've created a SSIS Solution and have created Data Sources. I have two packages. One was created before the Data Sources, and one was created after. The package that was created after is using connections from the Data Sources. I want to change the package before the Data Soruces were created to use them, but when I right click in the Connection Managers pane "New Connection From Data Source.." is not an option.
Did I not add it to the Solution properly?
How do I get it to show?
Did I not refresh something?
Please provide the how if you figure it out.
Thanks

For seting up the connection should we use Connection Manager or New Connection From Data Source?
The advantage of using Data Source is that we have the connection avalilable at project level but I've studied it somewhere that Data Source is used for SSAS not SSIS.
But I don't have enough explanation to give it to my team, that why I am not using Data Source.
We are working on VSS, do we have to reset the connection managers if want to test our packages on some other machine(else than the one on which it was developed)?

I have an issue when using Report Manager for viewing reports that use a certain Oracle data source. When viewing the reports in Report Designer the reports display without problems. But when trying to display the reports with Report Manager, after deploying the reports to the Report Server, I now get the following error message:
blablabla....ORA-12705: invalid or unknown NLS parameter value specified
For testing purposes I am running Report Designer, Report Server and Report Manager locally on a PC with Windows XP. I am using Reporting Services 2005, IIS 6, Visual Studio 2005, an Oracle 9.x client and an Oracle 9.x (not 100% sure) database that is hosted on a remote server.
Earlier I got an error message that stated "ORA-12154: TNS: could not resolve the connect identifier specified". Access rights to some Oracle folders for the Network service account did the trick here but then I got the "NLS parameter" error message. What I have tried to do is removing the NLS_LANG register variable and also modified the value of the variable so that it matches the value of the NLS_LANG variable on the server that hosts the Oracle database, but none of them have worked. Any ideas?
Maybe this is an issue that is more appropriate in an Oracle forum but what the heck..the problem could reside in Reporting Services..
Thanks, Stefan

I changed one data source settings in my SSIS project to use Windows Authentication instead of SQL Authentication. This data source is used to create connection managers in all SSIS packages. Soon after the data source was changed, when I opened any package using the connection manager that is based on this changed data source, I got an alert message box like the one given below showing different connection strings in data source and package connection manager. That's understandable (why can't VS 2005 do this silently or give an option to let this happen silently? that would be nice.).
Here is the problem. Even after both data source and connection manager are synchronized, still the same message box keeps on coming when ever I open any affected package (about 20 packages!). It is very annoying as you can see that old and new connection strings ARE IDENTICAL, still VS 2005 is not able to recognize this. I installed VS2005 SP1 even before I ran into this problem. I asked my friends to open this project and check the behavior on his machine. Same thing. Is this a known bug? How to fix this problem? Thanks for your help.
=====
Message box "Synchronize Connection Strings" (VS 2005 status bar shows "Performing post package load operations"):
This package contains at least one connection which is based on a datasource. The connection string for conenctions and data sources listed below are currently not identical. Connection strings of connections will be updated to reflect those on the datasource.
Connection: SqlServer.NET.HBI_DW.hbiuser
Data source: SqlServer.NET.HBI_DW.hbiuser
Old Connection String: Data Source=SDAL1060DB;Initial Catalog=HBI_DW;Integrated Security=True;
New Connection String: Data Source=SDAL1060DB;Initial Catalog=HBI_DW;Integrated Security=True;

I have a Rounding error: Between flat file connection manager Source & OLE DB Connection Destination (SQL Server 2005) in my Dataflow.
File looks like this lets call column names Col A,B,C,D

70329000 ICD 11025.84 3353.88

Problem: ColA (Source) Rounding error to PARTY_NO (Destination)
I have a field of text of in a flat file that the flat file connection manager Source picks up correctly €œ70000893€?
However when it gets the OLE DB Connection Destination the data has changed to 70000896. That€™s before its even Written to the database.
The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07
Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00
ColA (Source) PARTY_NO (Destination)

I'm trying to create a DataReader source object using a working ADO.NET Oracle Client connection object that exists in the connection manager.
Problem:
When I open the editor the DataReaderSrc component shows only one row under the Connection Managers tab:
Name=IDbConnection
Connection Manager=blank
Description=Managed connection manager
I cannot assign the ADO.NET connection (or any connections). I see a warning at the bottom of the Connection Managers tab:
"Not all connection managers have been set. Set all connection managers."
When I click refresh the warning message changes to:
"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
I am prevented from removing the IDbConnection or assigning my Connection Manager object to the DataReader Source.
Thanks, -- Mike

[One day I will come back here and answer questions, rather than only ask.]
I have a custom connection manager that returns an OleDbConnection. The only thing "custom" about the connection manager is how it determines its connection string. The object returned in AcquireConnection is an OleDbConnection.
Code:public override object AcquireConnection(object txn)
{
UpdateConnectionString();
OleDbConnection oleDbConnection = new OleDbConnection(this.connectionString);
oleDbConnection.Open();
return oleDbConnection;
}
Some of the objects within SSIS only work with an OleDbConnection, but mine is not recognized as such. Is there any way to have my connection recognized as a valid connection?
Thanks in advance.

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?
Can someone tell me what is wrong?

I am testing an application that uses mysql that works 100% fine with Microsoft Windows XP on Windows Vista Premium Home Edition.
Using Vista's ODBC Data Source Administrator I have set up and successfuly tested the DSN Connection to the Database.
However, when I call the set up DSN with the application I get [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
I am using the mysql-connector-odbc-3.51.12-win32.
I have tried editing the registry DSN files - the problem still persists.
Does anybody know a way to solve this problem

We are going insane trying to start Report Manager on a SQL Reporting Services 2000 installation. The programmer/admin who originally set this up for us is gone.
We recently upgraded a database/application server to a new server, causing the data source being used by reports in reporting services to no longer be valid. Unfortunately, we do not have access to the original report project to 're-deploy' with the corrected data source.
We desperately need to get the reports that are installed to retrieve their data from the new database location/machine. We understand this can be done by specifying a new data source in Report Manager. (To clarify, we have NOT moved the report servier installation or database, these remain in place - it's just the deployed reports that no longer point to the correct data source.)
For some reason, our Report Manager will no longer run - when we try to launch it, we get a windows login dialog - nothing will work here. We've tried both local and domain admins and constantly get ACCESS IS DENIED 401.3 error messages that we do not have permission/problems with ACL's.
We've gone so far as to allow EVERYONE read/write access to the ReportManager and ReportServer folders and the RS virtual directories, but nothing seems to help.
Can anyone help with this? Ideas on how to change our data source, or how to get back into Report Manager?
Since we are somewhat technical, but not experts, and don't have much more time to waste, we are willing to pay $500 for this project to someone willing to access the server and fix the problem so that the reports point to the correct database and restore access to Report Manager.
Thanks in advance for any help.

Hi SQL Server Team,
In order to add a data source by using ODBC Administrator, programmatically i am using SQLConfigDataSource. Thus calling SQLConfigDataSource with the fOption set to either ODBC_ADD_DSN for creating a new DSN.
Following is the stattement specified in the source code. where type_of_driver = "Microsoft Access Driver (*.mdb)"; and parameters contains the data source source credentials information such as DSN, UID, PSW, FIL, Description, DataDirectory,DEFAULTDIR and DBQ all separated by " ".
rc = SQLConfigDataSource(NULL, ODBC_ADD_DSN, type_of_driver, parameters);
after execution of below mentioned command an error is encountered i.e -1 is returned if the DataDirectory path exceeds certain nested directories link. for eg. the file path specified below.
C:My DocumentsClients CurrentAHW Netcare BenefitsDeliverables1-5 Results Chain - system LevelAlberta NetcareBenefits Logic System Level V01.rcm
Creating a datasource with the file name i.e Benefits Logic System Level V01 every time.
rc = :: SQLConnect(hDbc, (unsigned char *)szSource, SQL_NTS, (unsigned char *)szUserName, SQL_NTS, (unsigned char *)szPassword, SQL_NTS);
Also following error message was encountered during execution of SQLConnect command.
/*szErrorMsg = 0x0012e834 "[Microsoft][ODBC Microsoft Access Driver]General error Not enough information to connect to this DSN with SQLConnect. Use SQLDriverConnect."*/
Thus followed the instruction smentioned in the error message an dtried using SQL DriverConnect() in the following manner.
rc = :: SQLDriverConnect(hDbc, NULL,(SQLCHAR *)"DSN=RCM",SQL_NTS,outstr, sizeof(outstr),
&outstrlen,SQL_DRIVER_NOPROMPT);
Still an error is encountered but this time it returns a RETCODE of 100 whrease earlier it had returned -1.
Inform the procedure to be followed using SQLConnect when DataDirectory path is too long.
An early reply will be appreciated.
Cheers & Regards,
Saresh

Hi,
I am working on SQL Server 2005 (x64) with Windows Server 2003 (x64) operating system. I am having a major issue in SSIS. Here is the detailed explanation of the issue :
I have an EXCEL file in 2003 / 2007 version. It contains some data. I want to import the data using SSIS into SQL Server 2005 (x64) database table. I have taken "EXCEL FILE SOURCE" and "SQL Server DESTINATION". It was failed on importing data. Surprisingly it works fine in SQL Server 2005 (x32). Can you please explain why it is NOT woking on (x64) ?
Here is the error code i am getting:
[Excel Source [1]] Error: The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0202009.

Was wondering if there was a best practice minimum permissions for creating a SQL login to use when setting up a new shared Data source for SSRS report manager?
Something along the lines of them being a data read for the DB and permissions to update tempdb?
Would have thought it not advisable to have the login be able to update the main db...

Greetings,
I have an SSIS package that I need to modify. It was developed in Visual Studio 2005 and runs faithfully in production on SQL Server 2005. Suddenly, I can't open the package on my own workstation. I see a big red "X" image and a message stating "Microsoft Visual Studio is unable to load this document." The real reason the document can't be loaded appears to be:
Error loading DataWarehouseLoader.dtsx: The connection type "OLEDB" specified for connection manager "Warehouse Logging OLE DB" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name.
Does anyone know what causes this and what I can do? The package has been in production for 9 months and I've never seen this problem before.
Thanks,
BCB

help - I€™ve been stuck on this for days.
My software vendor limits the sessions to one (1) per log-in to Oracle 9i and I€™m having tons of problems trying to extract data through an SSIS package. Everytime I run the package SSIS already logged in and the OLE DB source fails because of the sessions exceeded error.
Is there any way to limit the connection to just when I need the data to pump across on the OLE DB source?
Thank you very much for any help.

I cannot get this error resolve either for myself or any users, and I'm actually part of the Admin group! Furthermore, a user with whom I'm tring allow to view this report keeps getting prompted for their windows username and password. I thought that since this datasource was set to Windows Authentification that it would just pass it through?
I'm pulling my hair out at this point:

Hello everyone,
I posted the same issue before, but I couldn't find the solution yet. I am posting this agian cos I tried almost everything and I am not able to solve the issue.
Let me explain what is happening here:
Server A - is my development local machine
Server B - is the remote reporting server, where all reports are deployed
Server C - is where the databases are located
- After successfully deploying the project (the reports and datasources) on the remote server and try to run the report , I am getting the following error message
An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'dsCallB'. (rsErrorOpeningConnection)
For more information about this error navigate to the report server on the local server machine, or enable remote errors
- I tried to deploy and run the same report on my local machine report server(Server A), which is still accessing the same database from Server C. This works fine.
So from this we can understand that A ==> B ==> C is not working, however A ==>C works fine(using Server A as a report server).
I almost tried all the possible solutions that are posted on the forum, such as storing the credential information on the report server (server B), created a data source, which is not a shared data source, on the report server level e.t.c. and I ended up with nuthin.
The weired thing is that there are existing reports that are already created and deployed(by somebody else) in the report server (server B) , which access the database on Server C. These existing reports run with no problem, even I can create a report which uses the existing data source and runs perfectly. However, when I create a new report which uses a different data source (from Server C), and deploy it to Server B and tried to run it, the above error message comes.
Please let me know if you have any idea.
Thx.

I tried running the report from an server (where reportingservices is installed) finding that all the reports works as they should. I logged in another server with the same credentials. I got same message on the server as I get on my own camputer, "Cannot create a connection to data source ..."
Is there anybody out there having same problem as I, or someone who has any suggestion?

Firstly the disclaimer: im a total SSIS bunny.
Ok, with that out of the way...
What i want to do is have data read from an MSMQ message (which will be a simple XML message) and have it transformed and inserted into a simple table. Sound simple, but i cant work out how to do it.
I started a new Integration Services Project and dropped a Data Flow task on the Control flow tab, then double-click it to go to the data flow tab. I have added a MSMQ connection manager which points at my private queue and i can hit the test button and it sees it tests ok. How do i wire that into my data flow?
On my dataflow tab i have a SQL Server Destination (set to the local SQl server instance) and ive been trying a DataReader source and try setting the Advanced Editor "Connection Manager" column on IDBConnection row to point to my MSMQ connection manager. I get some error "cannot aquire a managed connection from the run-time connection manager". How do i get a Data Flow source which reads the XML message off my MSMQ connection manager??
On the Control Flow tab you can add a Message Queue Task and i can bind it to my MSMQ connection manager and set it up as a recieve task etc, but how do i use that?
Help!

I have a task that uses an Excel connection manager to read in an Excel file. In the file there are 6 date columns. The date columns can have either a date or the letters NA. If I look at the External Column properties from the advanced tab, 4 of the date columns have a datatype of DT_DATE. The other 2 date columns have a datatype of DT_WSTR. The 4 columns with DT_DATE, my data looks okay as when it is read by the connection manager. The issue is that the 2 columns that are DT_WSTR, all dates are turned into NULLS, while the NA's are just fine. I have tried to change the datatypes in the advanced tab to DT_DATE, but it won't work.
I don't have any idea what to do to get this working correctly. Can anyone PLEASE provide some insight and suggestions or a solution?

Everything is set up the way it should be, as far as we can tell.
However, when we drop in a SQL data source and try to configure, it, we
get a blank box for choosing the connection string, and it won't let us
make a new one.
Has anyone encountered this before? If so, how can we fix it?
