Deleting Old, Unused Connections From Connection Manager Causes Errors
Oct 29, 2007
For some reason, when I try to delete old DB connections from the connection manager, it causes compilation errors because it is not removing the references from the meta data. I get Object ID errors where it is still trying to find the connection after it has been deleted. I have tried going to the code behind and searching then deleting the invalid reference, but that still does not work. I have a connection for 2 totally different databases that are no longer being used in the SSIS package and I would like to get rid of them.
As I was developing my SSIS package, I created several variables and tasks ( FTP, WMI Reader Task ). I am now cleaning up, deleting unwanted variables and connections in the design window. I save and build the package and when I load the package, I get warnings that these variables are referenced but can't find them and errors that the WMI connection is not found.
When a package calls a sub-package, it stores the absolute path of the child package in its dtsx xml file in a Connection String property. How annoying !!! . When I deploy this to another machine with a different file structure, it becomes a problem. Why can't it store the path relative to the parent package, which would be typically in a sub-directory under the parent ?
These last 2 days have been nothing but frustration and my deadline is slipping. Any help is appreciated.
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?
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?
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 source will fail.
I have it so that for each iteration if the transform was successful the file is moved to an archive directory, and if it fails the file is moved to a different directory.
But I don't want the package to be marked as failed. For the control flow tasks I have set the individual components to FailPackageonFailure = False, and for the Data Flow tasks I have set ValidateExternalMetadata = False.
It no use to set the MaxErrorCount higher because I can't guarantee how many files will be processed and how many might fail.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
I have an old DATABASE that is not more in use , so I want to drop that database. But before that I want to check that is there any application running on it or not.
Purpose: Need to import excel source data into SQL Server 2005 tables. Excel source data comes in nulitple excel files with the same structure but different data. I would appreciate someone taking a look at the following information and notifying me of what I am doing incorrectly.
I Inserted a foreach loop container, a data flow task located inside the foreach loop contaiiner, an excel and SQL Server 2005 connections.
After trying multiple times I went the following URL and followed step by step direction on how to connect excel workbooks dynamically: http://msdn2.microsoft.com/en-us/library/ms345182.aspx . I also used http://www.sqlstrings.com/ as a reference when creating the connection string.
Creating a Foreach Loop Container:
1. Opened foreach loop container 2.Set the Enumerator to 'Foreach File Enumerator" and configured the enumerator by setting the directory location and file base name to E:ClientsDep CommBEABEA_Test_Source and *PersonnelExpense*.xls respectively. 3. Clicked Variable Mapping; created two variables called, "ExcelFile", and "ExtProperties" and closed out of the foreach loop container.
I. Created Excel Connection:
Created excel connection called, €śDynamic Excel Connection Manager,€? that initially pointed to one of the excel workbooks. Went to the connection properties by right clicking the connection manager. Expanded Expressions and clicked the ellipsis button to bring up property expressions Chose Connection String in the Property. Clicked the Expression Ellipsis button. Put the following inside the Expression multi line text box: A. "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::ExcelFile] + ";Extended Properties="" + @[User::ExtProperties] + """
Clicked the Evaluate Expression button to get the following:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=;Extended Properties="" Clicked Ok button Inserted a Data flow task inside the foreach loop container.
II. Configured Tasks that is associated with Dynamic Excel Connection Manager or Package:
Set the Foreach loop container Delay Validation to true. Set the Data Flow Task Container Delay Validation to true. Set the Dynamic Excel Connection Manager Delay Validation to true. Set the SQL Server Connection Manager Delay Validation to true. Set the Package Delay Validation to true. Package Locale ID set to English
Ran the package after connecting the excel source data flow to the OLEDB destination and have inserted part of the error in this post. Please see below.
Error: 0xC0202009 at Package, Connection manager "Dynamic Excel Connection Manager": An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Could not find installable ISAM.".
I modified the connection string after receiving the error by removing the extended properties. The following is the modified connection string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::ExcelFile]
I repeated step I.6 above and received the following expression: Provider=Microsoft.Jet.OLEDB.4.0;Data Source=
I ran the package and received the following error in part: OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Unrecognized database format 'E:ClientsDep CommBEABEA_Test_SourcePersonnelExpense_OCCs_051007.xls'."
I did not find anything helpful when I searched for the above errors and would very much appreciate anyone€™s assistance on this issue as this issue needs to be taken care of ASAP.
Does anyone have any ideas as to why I received this error and what can I do to resolve this issue?
Your assistance in this matter is truly appreicated! Thanks!! Lee
I am in the process of importing an Excel Spreadsheet using the natively connection manager in SSIS 2008. Â There is one column however that is causing me grief.
SSIS has natively chosen the problematic column to be a DT_WSTR(255). Â I have gone into the Excel connection manager's Advanced Editor and altered it to be a DT_WSTR(1000) (see image 1 attached).
I am still getting truncation issues though, as per image 2 attached. Â why this is?
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. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
component "Excel Source Service Contract Upload" (1) failed validation and returned error code 0xC020801C.
One or more component failed validation.
There were errors during task validation.
DTS_E_OLEDBERROR, Error Code: 0x80004005 Source: "MS JET DB Engine" Description : Path is not valid
I am unsure if i am managing my connections in the correct way... but as it stands we have them in a .dtsConfig file that each package references in order to get the relevant details..
This is working fine, except that in total our ETL project uses 6 different connections, and none of the packages utilise all 6.
This leads to an error message upon opening up EVERY package stating that there are connection strings in the .dtsConfig that are unused, yeah, thats the idea!
The way i have gotten around this, is to just include all 6 connection managers in every package, but my question is, is there a better way to achieve this same result??
are we going about this in a bit of a cackhanded way?
I'm a new user that is playiing with a few of the MS web tools available. I have been trying out the ClubDB sample as part of looking at visual web express. I have installed the sample and ran it in multiple directories while debugging. Most of the directories have now been delected. My problem now is that I cannot add back ClubDB and access it remotely because somewhere in the SQL database there are connections made for each of the previous "test" runs of the sample. I have run SSEUtil and deleted all connections involved (no clubdb or aspnetdb connections still connected) but that doesn't seem to fix it. For example, there still seems to be a table somewhere that remembers that I once had a "clubdb" connection in websitemainapp_data.
My questions are: - where is this information stored? - is there an easy to use tool to clear all of these persistant connections.
Hello every one i had a design question.What would be the best way to approach a problem such as a perventing unsed and left open sql connections i have written a class called DataBase Manger but my question is should this class be static or none-static. right now the way i have is something like this private SqlConnection Get() { SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["StringConnetionName"].ConnectionString); sqlCon.Open(); return sqlCon; } /// <summary> /// Closes a connection to the Database /// </summary> /// <param name="sqlCon"> Database connection to close</param> private void Let(SqlConnection sqlCon) { sqlCon.Close(); sqlCon = null; } then for example to run a store proc i have public int RunProc(string procName, params SqlParameter[] p) { SqlConnection con = Get(); try {
using (SqlCommand cmd = CreateCommand(con, procName, p)) { cmd.ExecuteNonQuery(); return (int)cmd.Parameters["ReturnValue"].Value; } } finally { Let(con); } } now every time in any class or method i need to create a new Database manager and call the run proc object. Would it be a better desing to make this class static? so it would be just DataBaseManger.RunProc(blah,blah) or is it a better OO design to have it the way i have it. is is more secure in a webapplication? can these connections be hijacked? thanks in adanvce, any help would greatly be apperiated. or any link to any related tutorials thanks,Amir
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 page that I have 3 connections. I've made sure that each of these are closed when they are not being used and opened just right before being used. I keep getting the error "There is already an open DataReader associated with this Command which must be closed first." This error might show up as being produced by a dataadapter or sqldatareader...I have many. I've even tried to make separate connections as some have mentioned for each...leaving me with 15+ connections. I have added "MultipleActiveResultSets=True" to the connection strings as some have mentioned. I just don't know where to go from here... Is it possible that the problem lies in multiple instances of this page being opened? Also, the data refreshes every 15 seconds. I really need this to work, but I have no clue on how to fix this problem. The error is easy to reproduce by opening up multiple instances, but some of the times is doesn't give an error at all?!
We have a strange problem occurring in an environment at a remote client that we're looking into. I was wondering if anybody else has experienced something similar.
We have a COM+ transactional component sitting on a machine that connects to a SQL server machine in the same room (ie no firewall between the two as far as I know, but I'll double check that to make sure).
This component was written in Delphi and uses ADO (sqloledb provider) to connect to the SQL Server. This works 99% of the time. However, there are times where we get the following error when trying to open connection (using the Connection ADO interface):
[DBNETLIB][ConnectionRead (WrapperRead()).]General network error. Check your network documentation
or this:
Connection failure
The error codes associated with these were found in oledb.pas :(-2147467259) $8004D01C and (-2147168228) $80004005
When this happens, it seems to last a few seconds (usually around 10) and then everything comes back to normal. I'm just wondering what could make this happen when the SQL Server seems to be responsive when we try to connect to it using other means. The SQL machine runs Win2k3 sp2 for testing purposes.
Since we were not able to reproduce it yet, I wrote a little application trying to connect to a sql server when it is set on pause. When I run it inside a COM+ transaction, I get the same errors as above right away, the third time I'll get an error telling me that SQL is in pause state, If I run the exact same code but inside a simple vbs application (ie no COM+ transaction), I only get the pause error message sometimes after a few more seconds, and none of the other errors above. Could it be that the COM+ transaction is trying to do other things and these fail so it returns another error? If so, how come after a bit I get the proper message?
Anyways, I'm pretty lost as to why this is happening and how we can try to debug it since we have not been able to reproduce it yet. If anybody has any clues, please let me know.
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.
Hello, I'm getting the following error when I use Enterprise Manager to view a database in taskpad mode:
Internet Explorer Script Error An error has occurred in the script on this page Line: 307 Char: 2 Error: Unspecified Error Code: 0 URL: res://C:Program%20FilesMicrosoft%20SQL%20Server80ToolsBi nnResources1033sqlmmc.rll/Tabs.html
If anyone has seen this before and knows the cause and a fix your help would be greatly appreciated. If it helps, the O/S is Win2K, SQL Server 2000 Standard edition with IE 5.5. Thanks and cheers.
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 €ś70000893€? 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 am getting frequently errors in report manager. When I open that log files, I can see some old logfiles in 2013. So now how to enable that logging feature again.
i.e. before that they enabled the logging in reportserver and disabled now?
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?
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?
