How To Add A Connection Manager At Runtime Within A Script Component?
Oct 29, 2007
Hi all. Sorry about bothering you again but I have no choice, I'm afraid. This time I have to add a connection manager at runtime. I have a script that examines rows in a huuuuuuuuuuuuge file and it turns out that I will have to redirect different rows into 95 different text files. I would like to avoid the pain of creating the files and connection managers manually. I have a source script component that runs asynchronously (the only way basically it can run as a source) and I wonder whether this time, when I change the connction string on the manager at runtime inside the script, it would run properly. Can anybode tell me, please?
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?
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?
At one point in my package I call a simple web service that kicks off a process on a remote server using a Web Service Task . I need to be able to point the task at a test instance while I'm testing and a different one when it goes to production. The simple answer (you'd hope anyway) is to just store the ConnectionString for the HTTP Connection Manger in Package Configurations for TEST and PROD. I did this and when the package runs, the connection manager's connectionstring does get changed, but the web service task doesn't use this value. It uses the value defined in the WSDL file which in my case contains the URL for the TEST instance.
Am I missing something obvious? Do I really have to get the WSDLs from PROD and TEST and deploy both of them to the appropriate environment? What does the ConnectionString in the HTTP Connection Manager actually do then?
I have been working with flat file connection managers for a while now, and I have found it very useful to set properties on all types of SSIS objects using expressions that are set to SSIS package variables.
We have recently moved towards using a centralized application configuration infrastructure, so we are now loading up all application configuration information from our own system -- it's actually based off of the 2.0 ConfigurationManager.
I have developed a custom control flow task that will retrieve all of the SSIS variable information from our own application configuration system and set all of the SSIS variables as the first step in a package.
When I have been using this to set the SSIS Variables which are used in expressions for the HeaderRowsToSkip and DataRowsToSkip (there may be others, but I have not tested them yet) properties of flat file connection managers, these values are not being used -- instead it is using the values for the variables that are defined in the package itself (i.e. the default values that I set up in BIDS when developing the package). The ConnectionString property on the flat file connection manager does not exhibit this behavior.
Can anyone provide any insight on this? Is this a bug in SSIS, or is there something that I am missing here?
The standard flat file connection component does not handle flat files with different column counts on different rows. Since that's the type of file I have to read, I like to create a modified version of the flat file connection manager that can do this. I have found some info in how to create a connection manager. But I can't find anything that tels me how to build one that would be recognized by the flat file source dataflow component.
So how do you build an connection manager that can used by the standard flat file source component? Anyone ever did this or knows were to get the docs?
I know my problem is also solvable by reading the row into a single column and then using a script component to split them but that is not the solution I want.
I have written a script source component and attached a flat file connection. The connection string of which is defined by an expression.
However when I get the connectionstring from the connection in the script it has the default filename value of flat file not the value of the expression. This is proved by passing in the filename variable, and comparing the 2.
The flat file has an expression on the ConnectionString of @[User::filename]
Within a data flow I have a script component that I want to perform some data calls from. I want to execute SQL commands to connections already defined in the package's connection manager.
Is there a way to set my script's connection variable to the connection manager connection? Or, can I use the connection manager connections directly from within the script?
ConnectionManager manager = Microsoft.SqlServer.Dts.Runtime.DtsConvert.GetWrapper(base.Connections.Connection); IDTSConnectionManagerCache100 cache = manager.InnerObject as IDTSConnectionManagerCache100; if (cache != null) { Â System.Windows.Forms.MessageBox.Show("Cache is found."); } and use IDTSConnectionManagerCacheColumn100 id = connMgr.Columns["Id"]; get the column info.
but how do i get the cache connection content ?I want to look in the content in a script component code.Â
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.

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.
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.
1. Deletes a SQL Server database. 2. Recreates it with the tables ready to take data. 3. Executes a Flow Task that puts the data into the tables.
So far so good. The problem I have is that everything is loaded correctly as long as the tables are in place before I try to execute the package. When the first step deletes the database I get an error because the connection manager cannot find the tables that are defined in the database that has been removed and the package seems to disregard the fact that before the data gets loaded the whole structure will already be in place. What should I do to convince the package that the connection manager will have the target database set up when the data needs loading?
How can i change the connection string at runtime?
Scenario is, I want my customer to enter server name, database name, and some parameters at the installation time then i will use these entries to build the connection string and persist it into the app.config.
also not only at installation time but also at runtime while the program is running. i wanna make these entries as options which can be modified at any time
I used to do this in DTS but wondered how to do it in SSIS. I have a For Each ADO recordset loop that reads these four columns into variables:
DataSource Name, Name(for a WHERE clause), user and password.
For each "Building" there is a new server to connect to, with identical tables. I have 10 tables in the loop to pump from one database to a SQL 2005 database (i.e. 10 dataflows). I want to set the source connection information with the variables. My questions:
1. How do I set the connection information for the source connections? Do I just set the properties for the connection manager and then it sets for all the sources? What property do I set--do I need a script task?
2. How do I use the values from the "Name" column in a WHERE clause in each data flow?
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!
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.
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.

I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.
Package works from my computer. But when I execute it on the server as a SQL Agent job, I get
The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I copied the mdb file to a folder on the server which my packages have no problem reading data from.
My packages run under the same domain account as defined in proxies.
I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.
My expression is as follows:
DataRowsToSkip : @[user:: Var]
where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.
I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.
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?
