Posted By:      Posted Date: October 19, 2010    Points: 0   Category :Sql Server
 

I've got a package which reads a text file into a table and updates another.  I set up configurations so that I could import it into the SSIS store on both my dev and live servers.  Now, I'm getting this error.  I tried removing the configs and am still getting it.

I've been through each step and everything looks okay.  Does anyone have any idea (a) what's wrong, (b) how to localise the error or (c) get any additional information?  Or do I just have to recreate the package from scratch?

"No description found" when adding new connection to package connections collection (2005)

  

Hi -- This is driving me bananas.  I've got some VB.NET 2005 code that tries to create a new SSIS package programmatically.  Problem is, the code is failing when a connection (of any type) is added to package connections collection.  Here's a code excerpt:

Private connMgr As ConnectionManager

  Public Function AddConnection(ByVal pkg As Package, ByVal connType As String) As ConnectionManager
    <strong>connMgr = pkg.Connections.Add(connType)</strong>
    Return connMgr
  End Function

If I try to pass in the package I'm building with, for example, "OLEDB" as the connection type, the .Add method raises this error:

 {Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException}
    Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: {"No description found"}
    Data: {System.Collecti

Getting the Error: 0xC001000E at : The connection "" is not found. SQL 2005

  
After doing some looking I noticed this was included in the SP3 for SQL 2005. We have had this service pack installed for a while now but we are still randomly getting this error. Some packages will run fine for a long time and then all of the sudden start giving this error even though the package was successful. Any ideas? Thanks, Donnie

Hi,

I've created a small website with a simple sqlite database using vwd 2010 .net 4. In dev and test envionments everything works fine, however when i promote to my hosting provider i receive the following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I've been configuring the connection strings (autogenerated from entity framework and attached db) but unable to get it working on the hosting provider, I'm assuming it's related to permissions but not entirely sure how to resolve - here's the web.config as it stands:

site collection 404 not found error

  

Hi All,

Over the past few weeks we have been using the Sharepoint 2010 wiki site collection quite happily. Yet today it stoped working providing only a single line 404 NOT FOUND response.

 

We are not aware that anyone made any changes and when looking in the central administration we see nothing that indicates that that site collection is out of the ordinary.

Can someone please describe the steps we should take to determine what is causing the 404 NOT FOUND error. Once we learn how to idetify a cause for a problem we woulld be so much better equiped to solve potentially solve the problem.

Kind regards,

 

Ed

Error loading dtsx: The connection is not found.

  

We have several SSIS packages that have been running fine.  The last time they changed were on 01/30/2009. 

We're using package configurations pointing to a SQL server table (sql 2005).  The packages run from one clustered computer, which has a default instance of sql server enterprice on 64-bit machine, the connection is to another clustered box, which has a named instance of sql server.  All of a sudden we started getting "Error loading dtsx: The connection is not found. This error is thrown by Connections collection when the specific connection element is not found."
The server team swears nothing has changed.  I'm at a loss.  When I open the package on the server in BIDS, still get same error.  I keep having to re-add the connection and save.  If I re-open it gives the same errors all over again.  All our SSIS packages are stored on the file system, protection-level is "don't save sensitive".

Table entry for this connection is:  ConfiguredValue = "Data Source=HQESQL4\HQESQL4;Initial Catalog=ETL temp rep;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;", PackagePath = "\Package.Connections[ETL temp rep 4 Database].Properties[ConnectionString]"

a network-related or instance-specific error occurred while establishing a connection to sql server

  
I installed a new installation of SQL 2008R2 server on Windows 2008R2 server. First I can not connect to it with SQL management Studio 2005 so I wanted to install 2008R2 and I can not install it and that first. I used a PC with SQL management Studio 2008R2 but I can not connect to the database and I receive the following error "a network-related or instance-specific error occurred while establishing a connection to sql server, the server was not found or was not accessible.

A network-related or instance-specific error occurred while establishing a connection to SQL Server.

  

I have looked all over and tried every suggestion to resolve this issue but it persists:

I am trying to connect to an sql server on a windows 7 machine from an asp.net application.  When I am in Visual Studio I can use the connection in sqldatasource controls and everything is fine when I test the queries.  However, when I attempt to run the application I get the error.

I've tried:

1) Turning on named pipes on the database server and restarting the server.

2) Stopping all firewalls on the server.

3) Making sure that the server is configured to allow remote connections.

My connectionstring is:

Data Source=MYSERVERNAME\mssqlserver;Initial Catalog=NEMO;User ID=sa;Password=password

I have tried using portqryv2 to see whats happening on the UDP port that sql server uses as suggested in another post but gets a syntax error from the utility.

I am baffled by this one and would greatly appreciate some help.

Thanks.

Handling 404 page not found with Error page

  

Hi,

      How do i handle 404 page not found?


urlrouting - page not found error

  

I have a dynamic data site setup and running locally fine from vs 2008.

When i deploy to a remote windows 2003 server (IIS6), all the pages also work ok apart from one page/table.  I can access it's list page,  but the edit and insert pages throw 404 errors.

I'm thinking it's a url routing/hosting issue as i've copied back the database from the remote server and it all works fine on my local machine.

Is there anything i can do to debug this behaviour?

Below is my register routes entry from the global.asax

Any suggestions greatly appreciated as, i've been stuck on this for days :(


public static void RegisterRoutes(RouteCollection routes)
{
    MetaModel model = new MetaModel();
    model.FieldTemplateFactory = new AdvancedFieldTemplateFactory();

    model.RegisterContext(typeof(Sponsorship.Data.Entities), new ContextConfiguration() { ScaffoldAllTables = false });
    model.DynamicDataFolderVirtualPath = "~/admin/DynamicData";

    routes.Add(new DynamicDataRoute("admin/{table}/{action}.aspx")
    {
        Constraints = new RouteValueDictionary(new { action = "List|Details|Edit|Insert" }),
