Connection Manager Reuse For Oracle And SQL Databases
May 2, 2008
I'm trying to implement a configurable way of executing a group of SQL statements using either an Oracle or SQL database as the source for the data.
I'm currently building a connection string with a Script Task and then assigning it to a package variable so that it can be used by a connection manager but this only works with a SQL OLEDB connection.
I'm holding all the connection details in a database table, hence the need for the scripting but would it be possible to extend the task to reuse a single connection manager by changing it's properties?
Hi, I dont know if I should post this question here, or on oracle forums, but here goes ...
I made a simple package that performs 2 Excecute SQL Tasks, one task does a select query on a SQL Server DB Table, the other task does a select query on an Oracle DB Table.
The package runs fine in BIDS when debugging, but when I deployed the package to a file system and added it to an sql server agent Job, it all went wrong ...
I tried the ms oledb dataprovider (ole db) for oracle but also the oracleclient data provider (ado.net) but the package always fails.
message Failed to acquire connection "aaa.bbb.oracleClient". Connection may not be configured correctly or you may not have the right permissions on this connection.
the OnError logrow for the package itself says almost the same.
Now my question is: What do I need to configure to get it all working? I think I need to configure the oracle db no? What should I configure? ...
Is there a way in SSIS to change the database connection to sqlserver or oracle or db2 without choosing the connection manager in the source.
For e.g. I ran a package which is reading data from sqlserver and later i want to connect to oracle to read the data but without changing the connection manager in the source.
Basically, i want to find out from you gurus is about a way to switch between databases without changing the connection managers. OR the only way is to make different sets of packages for oracle / db2 and sqlserver sources ?
Hi, I want to import data from Oracle database programmatically using ODBC connection manager. I was able to import data by creating an ODBC DSN and then using it BIDS with ADO.NET connection using ODBC data provider for Oracle. Now I want to do the same programmatically. How should I create a connection manager? I tried using code below
But I get an error when acquiring connection ErrorCode=-1071611874
The connection manager "__" is an incorrect type. The type required is "__". The type available to the component is "__". Which one of the connection managers given by Microsoft here should be used? http://msdn2.microsoft.com/en-us/library/ms136093.aspx Has anyone come across similar scenario?
I am using the Oracle Provider for OLE DB (32 bit) to connect to an Oracle 10g database. I enter all the connection parameters and test the data source and I it says that the connection is successful. I then open the connection manager for the data source and see that the password has disappeared.
After reading entries on this forum, I tried to setting the package permission to UserKey, Password and others. Still no luck. Then I created an XML configuration file and set the connection string and password there as well. Still no luck.
Below is the message I am getting:
Error: 0xC0202009 at Package1, Connection manager "******": SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21.

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..
I am using SSIS 2005 on Windows 2003 server. Using Excel Source to dump the data for staging database. I am getting following error while I execute it through BI studio's execute button.
I have deployed my packages into Sql Server and I am using Configuration File. As my Data Source is Excel, I have changed the connection string during deployment with Server Path. But I am getting the following errors. Actually the File Exist in Path. May I know What is cause of the issue? Do I need to give any permission to execute the package.
SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0202009.

I've added a typed DataSet and dragged a table across from the server explorer. When I click configure on the table adapter, then click previous back to the "Choose Your Data Connection" dialog. The only option is the new connection that was just created when I added the sql server to the server explorer. Is there anyway to reuse my existing web.config connection string? My goal is to have a single connection string in my web.config. Thanks. -David
We are running SQL2K5 and have a Web server with a family of sites all sharing an identical connection string to enable ADO connection pooling between them. Today for about 20 minutes we had several (all?) connections from one site that uses a specific DB get a connection reuse error which showed in out SQL logs:
DESCRIPTION: The client was unable to reuse a session with SPID #, which had been reset for conection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.
We also have SQL Server slowdown and log in problems from other applications that seemed a symptom of this, or some third unknown cause. Note, the # means the run-time spid number was inserted. The misspelling "conection" comes right out of sys.messages (it is not our custom error):
select top 10 * from sys.messages where message_id = 18056
The immediately preceeding error in the SQL Log was always: Message Error: 18056, Severity: 20, State: 29.
Where Severity and State vary, but "Error: 18056" is consistent, although I can find no documentation on "Error: 18056" through Google or MSDN.
Also, the "The client was unable to reuse a session ..." error seems not to be referred to anywhere.
In our IIS logs, the matching entries are of the form:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
and
Invalid connection string attribute
My questions: Does anyone have experience with this error? We have real good history with ADO connection pooling, but can a "bad" connection be pooled, and if so can it be "flushed" or the pool "drained"?
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.
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.
On my dev server I have working ssis packages that use connections Microsoft OLEDB provider for Oracle MSDAORA.1 and Oracle provider for oledb and OracleClient data provider.
I use one or the other according to my needs.
In anticipation and to prepare for the build of a new production server, I have build a test server from scratch and deployed to it the entire dev.
Almost everything works except Microsoft OLEDB provider for Oracle.
ssis packages on the test machine will return an error
Error at Pull Calendar from One [OLE DB Source [1]]: The AcquireConnection method call to the connection manager "one.oledb" failed with error code 0xC0202009.
Error at Pull Calendar from One [DTS.Pipeline]: component "OLE DB Source" (1) failed validation and returned error code 0xC020801C.
[Connection manager "one.oledb"]: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Oracle error occurred, but error message could not be retrieved from Oracle.".
I have used the same installers for OS, SQL and Oracle SQL*Net on both dev and test machines. The install and then the restore/deployment on Test went fine.
Does anyone could point me to the right direction to solve this issue?
I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error. Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
I use SQL Server 2012 and visual studio 2010.I created SSIS Project with task "Execute Package". Control flow view as: Package1 (execute package) -> Package2 (data flow).Data flow in Package2 view as: ADO.NET source -> ADO.NET destination.
When I started Package2, it's work. I havn't errors.But when I started Package 1 I have error "Unable to get managed connection from the Connection Manager runtime". In execution log I see that ADO.NET source produced this error on verification stage. Package failed on verification stage, not on execution stage.Why when I started Package 2 it work, but when I started Package1 (and Package1 started Package2) it failed?
Hi All, I am getting the following error if I am using the package "Transaction Option=Required" while running through Sql Job: The AcquireConnection method call to the connection manager "<connection name>" failed with error code 0xC0202009.
while I running the SSIS package on BI environment, I am getting the following error: [Connection manager "<connection name>"] Error: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D00A "Unable to enlist in the transaction.".
I know the alternative solution is to make the "Transaction Option=Supported", but in my case I have run the whole flow in a single transaction. I came to know that this has been fixed in the service pack1(ref. to http://support.microsoft.com/kb/914375). FYI.. some time it was running successful.
I have taken all the necessary step to run the SSIS package in a distributed transaction(like the steps for MSDTC) and also created the package flow in a sequence.
I was going through the link - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=160340&SiteID=1 but all those didn't solve my problem.
If anyone can help me it will be great. or it is a bug in SSIS?
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) 71167300 71167296 70329000 70329000 70410000 70410000 Any ideas people? Thanks in advance Dave
hi all, i got the error, when i run my package after deploy into the server machine; i can able to run that package in my local machine, if i deploy it to the server or some remote machine, its not running, and rises error messages, that says cant accquire connection from the connection manager;
the problem might be with the login name and password; i could not see any password in any of my config file, or connection manager while running the package. how to resolve this problem?? please help me!
We are looking at consolidating our servers. We would like to have a database server, which housing our databases. However, we have some SQL 6.5 databases and Oracle 8.0.1 databases. Does anyone know if it is possible to have both on one server? If not, then it sounds like we need two database servers. Thank you.
I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.
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.
This is the first time I have used SSIS, so please bear with the ignorance.
I have a super simple package that inserts x000's of rows into a temporary table. The data source is a file that the user will upload. I need to be able to tell the package what file to upload. I'm thinking the simplest thing would be to edit the connectionString property of the SourceConnectionFlatFile at runtime. Is this possible? What form should the file path be in (UNC, other)? And, are there any other considerations I should be aware of?
Is there a way by which we can make the Connection in the connection manager retry for a certain amount of time?
I have a DataFlow Task which uses a OLE Source which is connected to a database. there are time when the connection to the database is not available due to some transport level error. so i wanted the connection manger to make a couple of tries before giving up and saying that it was not able to connect and it timed out..
i have the Connect TimeOut and the General Timeout properties set to 0, but is there a way to retry?
My source files are in C:Process folder. File names are in the format proc*.csv
I am using foreach loop container to iterate over the files in folder "C:Process"
I have a user variable "filename"
The order of my tasks
ForEach - Data Flow task - File System Task
In Data Flow task, I have ole db source which should take the dynamic filename from user variable "filename". whats happening is when i give fixed filename, without foreach loop container the package is working fine.
with dynamic filename, I am not able to run the package because of ole db source Error - cannot aquire connection from connection manager.
Dts.Connections.Item("myADO.NET connection").AcquireConnection(Nothing)Dim conn As New SqlClient.SqlConnection(Dts.Connections.Item("myADO.NET connection").ConnectionString) conn.Open()
This seems silly, in that I'm not really using the same connection, but using the connection string of a connection that already exists. And, for my purposes, it's not working currently, because I've switched from Windows Authentication to SQL Auth... and the password isn't coming over in the ConnectionString property.How do I re-use the exact same ADO.NET connection I have in my connection manager in a script task? That's the recommended way to go, right?
I have deleted one of my file connection from Connection Manager (and
Executed ProcessTask which used it), however
trying to load the package I always get the error:
"Error loading MyPackage.dtsx: The connection "MyDeletedConnectionName" is not found. This error is thrown by Connections collection when the specific connection element is not found."
I tried to Clean, Rebulid my project, but it doesn't help.
Does anybody know, how to solve it? Where this reference is saved?
Hi, I'm on a shared MS SQL server, and I have access on 2 databases there.On the server there are many other database, I guess around 170.When I want to access my database I open enterprise manager choose the server from the server list and click on "databases" to list all databases. This last step (listing all databases) takes ages to complete, it takes something like 3 minutes to show all databases so I can click my database from the list and do my thing. Isn't there any way to only view my own databases and not showing the others. I can't access the others so there's really no point in showing them anyway, it only takes time.
IN the enterprise manager I could see my database server but could not see the databases.Bur I can see the databases and database objects in quesry analyzer. What should be the problem and how can see the databases from my enterprise manager. Thanks.
Please forgive my ignorance - I'm completely new to MSSQL.
Our office bought a set of Laserfiche licenses and had to also buy MSSQL to handle the database end of things. Part of my job is to make sure everything gets backed up. I want to use Enterprise Manager to back up the databases which seems straightforward enough - even though I've never done it.
Our Network Admin has installed a temporary USB drive to hold our back-ups until a more permanent form of media can be installed. He is using drive compression to maximize the space available. The server sees it as Drive F:
I created a folder on F: to contain my MSSQL Back-ups. Then I opened Enterprise Manager and clicked on SQL Server Group, which contains two databases:
(local) (Windows NT)
and
CYWD_IMAGE/LASERFICHE (Windows NT)
My understanding is that they both have to be backed up.
I clicked on the first one, then selected the Database Maintenence Plan Wizard from the 'Tools' menu. I stepped through the process (choosing 'all databases') until I got to the point where I could specify the back-up directory. I was able to browse right to the folder I created and choose it. I could then finish the process normally. The problem is that when I selected the second database (CYWD_IMAGE/LASERFICHE) and launched the wizard I was unable to browse to my folder. I could choose the F: Drive but no folder showed up under it. Oddly, it would not even show me my D: partition (just thought I'd mention that in case it is somehow relevent).
I don't see any difference in the properties tabs between these two databases. The obvious difference is the name, and that one says (local) and the other does not.
I really don't want to choose to dump the back-up into the root of F:
