Custom Connection Manager; Returning Recognized OLEDB Source?

Jan 24, 2008

[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.

The Connection Type OLEDB Specified For Connection Manager Is Not Recognized As A Valid Connection Manager Type - Why?

Mar 17, 2008

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

DFT OLEDB Source Returning Empty Rows

Nov 19, 2007

I have had at least 2 occurences of a DFT OLEDB source returning the correct number of rows but all rows are empty (they contain zeros or ''). This has happened in two different places in different SSIS packages within an ETL task. In one case the source was on a different server running SQLServer and in the other it was a different database on the same server as the SSIS package. This occured running on different servers, one with SQL 2005 SP2 and the other without. Both are 64 bit AMD systems running 64 bit SQL 2005. As there is a derived column transformation that has performed the derivation on the blank columns I assume the problem is with the OLEDB source but it could be with the data stream from the OLEDB source to to whatever follows. Has anyone else had this problem and does anyone know of a fix?

Failed OLEDB Connection: Cannot Aquire Connection From Connection Manager

Feb 6, 2008

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.

Thanks,

OleDB Connection Class In Custom Task?

Jun 9, 2006

I have OLE DB Connections set up in my connection manager (Native OLE DBMicrosoft OLE DB Provider for SQL Server). I would like to reference and query these connections from a custom task, written in C#. I currently reference it as follows:

using System.Data.OleDb;

...................................

OleDbConnection connection = (OleDbConnection) connections["MyConnection"].AcquireConnection(null);

What may be obvious to some (though wasn't to me, as I am new at this), when I run the task, I get an error saying that I cannot make this cast. After perusing the boards, I understand that this is because I am not making a cast to the right connection type. Well, that is where I am lost. What connection type (and corresponding library) do I need to reference? I want to continue to use the "Native OLE DB..." connection.

Thanks!

SSIS Dataflow OLEDB Source Issue With DB2 Connection.

Jun 23, 2006

Hi,

I have problem to extract data from DB2 table using SSIS dataflow task with OLEDB source selecting the data access mode with command. Here is the scenario.(Note:If I select the data access mode as a table then it works fine.)

If I use the data access mode as SQL Command then it is not working. i.e. the flow stays yellow in controlflow nothing happens in dataflow and I noticed the SQL dumper and proc completes. I couldn't find any log to verify the issue including the package execution results.Any of your thoughts will help me to resolve this issue.

Thanks..Mako

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

Integration Services :: Dynamic Database For OLEDB Connection Manager In SSIS

Nov 10, 2015

I am trying to dynamically change my initial catalog in a SSIS project. Each day I get a snapshot of data from the production server. I am performing ETL on that database and loading it into my warehouse. I am trying to put something together so that each day I get the latest snapshot and if its newer then my most recent one I pass that new catalog into the connection manager. I can already run the sql script to compare the two catalogs but I can't populate the connection manager.

Connection Manager Not Showing New Connection From Data Source...

Mar 30, 2007

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

Feb 9, 2006

I have an SSIS package which takes input from Flat file and transfer the data to SQL Server using OLEDB Destination Data Flow Item. The OLEDB Connection Manager used for the destination is configured to use SQL Server Authentication for the user €˜sa€™. The package works fine without enabling the configurations. But when I enable package configuration and save the configuration of the various connection managers in an XML configuration file and then run the package it gives the following error in the validation phase:
[OLE DB Destination [21]] Error: The AcquireConnection method call to the connection manager "<Connection Manager Name>" failed with error code 0xC0202009.
And after the validation phase is complete the following error message is given for the package execution:

Custom Connection Manager Doesn't Show Up In VS?

Dec 16, 2005

I've created a very simple custom connection manager, and I followed the deployment instructions at http://msdn2.microsoft.com/en-us/library/ms345276.aspx.  Basically, that was just copying the assembly to %programfiles%Microsoft SQL Server90DTSConnections, and then registering the asssembly in the gac.

However, when I open VS, right-click on the connection manager pane, and then choose new connection, my custom manager does not appear.  What am I missing?

Here is the class:

using System;

using System.Collections.Generic;

using System.Text;

using Microsoft.SqlServer.Dts.Runtime;

using System.Data.SqlClient;

using System.Xml;

namespace MyCoolCompany

{

Custom Connection Manager Or SSIS Provided One?

Jul 20, 2006

Hi,

I have been working with a client on a legacy application migration to SSIS and I found SSIS to be very helpful, as this is my first project using integration services I found myself in a situation where multiple solutions can work but I cannot assess the risk of using one or the other and the effort required for the implementation.

The situation is as following, we cannot touch the input files that come from the other legacy systems so I need to get information that is packaged following the next multipart schema:

&Header with context information from the source
&BatchHeader with context information from the batch (including format N)
- Data in format N
&BatchHeader with context information from the batch (including format K)
+Data in format K
&BatchHeader with context information from the batch (including format P)
=Data in format P

Etc... Needless to say that they can come in whatever order and they need different processing depending on the format. I have been tempted to use the techniq shown in "Handling Different Row Types In The Same File" from http://www.sqlis.com/default.aspx?54.

However, there are multiple issues that I have to resolve to do that: First is how to feed the pipeline with the Data in format N and then reparse them in an easy way cause the data that comes from the other system is very wide (aprox 120 columns), so using a parsing script is by no means a viable solution (I have multiple formats to handle). So I do not see a way to treat the data without using a Custom Connection Manager. Here comes my first question: Is there anyway someone can use the already provided managers to handle an scenario like this one?

Next comes the separation, which one is the wisest thing to do: Write again that to disk in as easier format or pass along that information to the next task in memory? The volume of data is in the order of hundreds of megabytes (100 to 200), maybe half a Gigabyte in the extreme cases. How about uploading that to SQL Server and work from there?

BTW, the production servers will have 6 to 8 Gb of memory and 4 to 8 processors (more or less).

Thanks in advance.

New Custom Flat File Connection Manager Component

Jul 6, 2007



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.

Custom Task + Connection Manager With Interaction To Visual Studio

Dec 18, 2007



Hi

I am running into issues with custom objects interaction with visual studio 2005.

1. Custom connection manager.
I am setting the name of the connection manager ( to standardize naming convention ) that user created, however when the CM is created, the name displayed in visual studio is still the default name even if the real name is the one i set. I have to do things like, edit it or save package - close - reopen, create another connection, ... etc in order to get it refreshed.

2. Custom Task
I am managing some variables in this custom task so that I will be adding and deleting variables in the package.
The challenge i am running into is, when I added 2 variables for example, even though the variables are successfully added to package, the Variable Window in visual studio designer will not reflect the new variables. I have to save package, close, and re-open in order for the variables to show up.

So this brings to my question - is there any way to tell Visual Studio programmatically to refresh the contents of these 2 sections, 1 is the Variable Window and the other is the panel containing the list of connection managers.

I have been searching around and found some clue about visual studio SDK but I still cannot find an exact way of doing it. Visual Studio SDK example tells you how you can access the Variable window as

framesList = new List<IVsWindowFrame>();

toolWindowNames = new List<string>();

// Get the UI Shell service

IVsUIShell uiShell = (IVsUIShell)Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(SVsUIShell));

// Get the tool windows enumerator

IEnumWindowFrames windowEnumerator;

ErrorHandler.ThrowOnFailure(uiShell.GetToolWindowEnum(out windowEnumerator));



IVsWindowFrame[] frame = new IVsWindowFrame[1];

uint fetched = 0;

int hr = VsConstants.S_OK;

// Note that we get S_FALSE when there is no more item, so only loop while we are getting S_OK

while (hr == VsConstants.S_OK)

{

// For each tool window, add it to the list

hr = windowEnumerator.Next(1, frame, out fetched);

ErrorHandler.ThrowOnFailure(hr);

if (fetched == 1)

{

// We successfully retrieved a window frame, update our lists

string caption = (string)GetProperty(frame[0], (int)__VSFPROPID.VSFPROPID_Caption);

toolWindowNames.Add(caption);

framesList.Add(frame[0]);



}

}

But i looked up the methods for IVsWindowFrame and it does not have anything to refresh the contents of the frame.

I thought about firing events but cannot find which one to fire.

Any help on this will be greatly appreciated.

Integration Services :: Custom Connection Manager Only Works In 32bit

Oct 6, 2013

I have a very basic / stripped connection manager with only one property (SSIS 2012). It works fine in design time (you can open the connection manager editor and change the value), but in runtime it only works in 32bit mode. The runtime-validate-method does work, but if everything validates OK then in 64bit it throws an error when you run the package:

Exception deserializing the package "The package failed to load due to error 0xC0011008 "Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.

Connection Manager Or Data Source

Feb 12, 2007



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)?

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

Can't Assign Connection Manager Object To DataReader Source

Sep 22, 2006



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

Oracle Data Source Connection Problem Using Report Manager

Jan 2, 2007

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

SSIS Data Source Vs Connection Manager Synchronization Issue

Apr 25, 2007

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
