Is Dirty Read Isolation the only option to import data from informix using SSIS consistently

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :

Hi there

I've got a package that imports data from informix database. I'm using iBM Informix ODBC Driver 3.50 with ADO.NET data source to import data. Every now and then the package fails with "Could not do physical order read to fetch next row" issue so did some investigation and found that its due to the lock issue. Most of the guys suggested setting up isolation level to "Dirty Read".

Is it the only option to import data consistenly without any error from Informix? Because with "Dirty Read" you get concurrency issue. 

My other question is; can we use the transaction option with isolation level available is SSIS to get around this issue and if yes then how to approach it. And if it's no then is it limited to oledb sources only.


Regards, Vivek

Read Binary Data which is nothing but a Zip file and unzip through SSIS 2005 SP2

Hi ALL, I need some help in developing a task. I have a source database which is Oracle and it has a ZIP file stored inside the database in Binary format. When I move this data into the sql server 2005 database I get the data as binary data. Now the task begins with SSIS, I need to read the binary data which gives us a zip file and then unzip this zip file and read the XML data which is present inside the Zip file. I beleive some one might have already developed this task can you share the solution with us. Note: As this has to be moved into production I dont have permission to use third party tools like Cozy roc or install winrar.exe and simpy calling this exe from the execute process task in SSIS.  Raju

Import a flat file with combined data into separate SQL tables using SSIS

I have a flat text file (comma delimited) that is essentially multiple files, each with its own format, combined into one file. The file is coming from an external software vendor so unfortunately we don't have much choice but to work with what we are receiving. Here is an example of what the file could look like: Customer Data CustID,FName,LName,PhNum,Email 12345,John,Smith,,jsmith@gmail.com 12346,Jane,Doe,8001111111,jdoe@hotmail.com Customer Plan CustID,PlanType,PlanName,PlanStart 12345,0,Plan1,01/01/2010 12345,2,PlanVis,01/01/2010 12346,3,PlanLf,04/01/2010 12346,0,Plan1,01/01/2010 Customer Payment CustID,LastPayment,Amount 12345,09/01/2010,100.00 12346,05/01/2010,50.00 There is an empty line between each 'section' of data. I adapted a VB script I found online that can take the incoming file and save off each section as its own file so that each one can be separately imported, but this seems inefficient. I'm really new to SSIS in general, but it seems like it shouldn't be that difficult to take the data, split it where there is an empty line, and then import each section into the appropriate SQL table. Any ideas would be most welcome. Thanks!  

Text was truncated with "nvarchar(max)" data type and size by using SSIS Import and Export Wizar



I am using SSIS Import and export Wizar to load data from Excel file, I have set the datatype as "nvarchar(max); those data are not biger than 1000 bits but was failed to transfer as the error says:

Import Excel file with Data Connection into SSIS


I have got an Excel spreadsheet with a Data Connection that I want to import into SSIS. The problem is that the Data Connection does not seem to run at the time the file is imported, so it only calls "old" data.

How can I set SSIS up to run the Data Connection first, or is there something I need to change in my Excel spreadsheet setup?

When a person opens the Excel file normally, they first need to "Enable" the Data Connection in the Security Settings. Once that is done the data will update immediately. I wonder if that is something I somehow need to change to make it work in SSIS?

SSIS import Excel with Data Connection


Hi guys, I am trying to use SSIS for the first time. What I am hoping to do is set up a scheduled job that will get SSIS to read an Excel spreadsheet on a regular basis and import the data out of it into an SQL Server database. Now my Excel spreadsheet uses a Data Connection to a different source and I want the data to be refreshed before SSIS imports it. Is that possible?

The problem I am facing right now is that the Data Connection does not seem to run before SSIS import the data. It keeps importing the old data that was sitting in the Excel spread sheet at the time it was saved last.

Is there any way I can tell SSIS to run the data connection first? Or is there something I need to do in my Excel file to ensure the connection is run?

By the way: the Excel file is set up to run the Data Connection immediately when it is opened normally in Excel, but the general user always first has to go into the Security Settings and enable Data Connections.

Thanks for the help!

Delimiter File Read Task Installer failed to show in SSIS Data Flow Items


I downloaded the Delimiter File Read and followed the instruction and installed it. The file is on the correct directory (>:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents) The file DelimitedFileReader.dll is there.

However, when I go to BI Development Studio and try to add the new task I can't see it in the SSIS Data Flow Items...it is not visible. Does anyone know why I can add/see it?

Using Conditional Split data Transfer in SSIS 2008

This article uses the Integration Services Conditional Split Data Transformation element to filter and transfer data from a set of flat text files to SQL Server database table. The concept can be easily extended to apply to any other source or destination such as Microsoft Excel. This scenario is useful in creating denormalized database tables in a reporting and analysis situation.

Custom SSIS Data Flow Component Not Showing in Toolbox or GAC

Hello - I have created a very simple data flow component for SSIS (Actually, I am following this example:  http://www.microsoft.com/downloads/details.aspx?familyid=1C2A7DD2-3EC3-4641-9407-A5A337BEA7D3&displaylang=en).  However, when I register the DLL to the GAC, I am unable to find the assembly in C:\Windows\Assembly - even though the GACUTIL says "Assembly Registered Successfully".  Furthermore, after copying the DLL to the PipelineComponents folder for SSIS (C:\Program Files (x86)\Microsoft SQL Server\100\DTS\PipelineComponents), it does not show in the "Choose Items . . ." dialog box of SSIS.   I am running SQL Server 2008 Dev edition, Visual Studio 2010 with .NET 4.0, and Windows 7 Enterprise 64-bit edition.  Any assistance/thoughts would be appreciated. Thanks!

SSIS Import/Export Wizard: "Unexpected Unrecoverable Error"

For whatever reason, whenever the SSIS Import/Export Wizard needs to display an error message, it throws up "Unexpected Unrecoverable Error" instead. The three buttons - Abort, Retry, and Ignore - all cause the wizard to close. I see some activity in Process Monitor that looks like DTSWizard.exe is probing around for some System.Web assemblies, and not finding them. I'm running 2008 SP1 on Win 7 x86, and I've reinstalled the client tools and Integration Services. Anybody else seen this issue? Should I file a report on Connect?
