Unused Connection Managers
Sep 7, 2007
Hi,
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?
any incite would be useful..
Best Regards
Chris

Hello Experts,
I€™m new at SSIS and would like to try the follow easy function.
Just get some data from my database und put into a text-file.
All function going well.
Right now I€™ve got just one problem I can€™t resolve.
At the window €œConnection Managers€? are the connections I used in my project. But how can I make this connection more dynamical? E.g. I have a connection.txt file and the Connection Manager should set his properties after read this txt-file.
Have someone an idea?
Best regards,
Alex

apologies if this is the wrong group ..
whenever I create an Integrated Services project and attempt to add a Connection Manager I get the error
Connection Manager 'blah' is not properly installed on this computer.
(Microsoft.DataTransformationServices.Design)
This happens with all menu options except New Connection..
I have uninstalled and reinstalled both Visual Studio 2005 and SQL Server 2005 and made sure I have selected everything in each case
what am I missing?
Thanks
Chris

I'm trying to create a new package and keep getting different errors. The package uses the same .NET ODBC provider as another package.
I can test the connection fine.
When I add a DataReader Source and select my connection I get the following warning:
Not all connection managers have been set. Set all connection managers.
If I click the refresh button I get this warning message:
Error at Data Flow Task [DataReader Source [6338]]: The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID.
All my collections have ID's and they are all read only.
If I ignore those warning I can enter my SQL command and go to the column mappings tab and see all the columns I selected but I then see several warnings all saying the same thing.
Driver does not support this function
I'm not able to close the Advanced Editor at this point.
Any ideas?

I'm trying to create a custom connection manager and I have ConnectionType in the DtsConnection attribute set to "MSMDM". When I tried to create one in a package I got:
The connection type "MSMDM" specified for connection manager "{A8543B4B-41D9-4E69-9580-3D1A491AD719}" 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.
(TestHarness1)
So, a few questions:
What are the valid connection manager types?
Why can I not create a new connection manager type of my own?
If I cant create new connection manager types then the purpose of being able to build custom connecton managers is defeated. Hence, what's the point in giving us the ability to create custom connection managers?

Greetings my SSIS friends
This is probably a silly question but what exactly is the purpose of creating Data Sources when it is possible to set up individual connection managers?
Thanks for your help in advance.

I am not seeing an option to use the OraOLEDB.Oracle driver when defining connections in ssis. This driver shows up in management studio when trying to create linked servers so I don't know why it wouldn't show up here. All the client tools are installed fine and the linked server works. Any ideas?

Hi,
My database admin just migrated my packages from development to user testing server.
My packages configured to read the connection manager properties from the .dtsconfig.
But I am getting "The connection "CRPRDNMSQEZ.CIReporting2" is not found"
CRPRDNMSQEZ.CIReporting2 is being my connection manager.
I did find and replace server name in the dtsconfig but I guess it didn't work.
Any help is appreciated.

Hi,
We are using a €œFlat File Connection Manager€? in our SSIS package.
The package fails occasionally while loading in the validation phase with the error
€œ-1073659899,0x,The connection type "FLATFILE" specified for connection manager "<some name>" 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.
This error is not returned always.
Also I feel €œFLATFILE€? is a valid type of connection manager. This value €œFLATFILE€? is inserted by the editor and not manually typed. This is a weird behavior of SSIS.
Sometimes I get this error with respect to some other connection manager used in the package as well. €œOLEDB€? is the type of that other connection manager.
Has anybody faced similar issue earlier?
Please let me know some thoughts, suggestions, and possible work-arounds to avoid this error as this is very critical for us.
Regards

Hi Experts here,
Sorry if this query had been raised earlier. While In DTS Packages we retrieve connection details for all Connections in a Package from a table and then assign them to the following global Variables
gv_Source_User, gv_Source_Pwd, gv_Source_DataSource, gv_Source_InitialCatalog
Finally we reassign these variables to repective Connection Properties using Dynamic Properties Task. After Migrating to SSIS though we are able to assign almost all variables to Properties of Connection Managers via Expression except the Password which we donot find in the drop down list in order to assign gv_Source_Pwd.
Is there any work around to assign passwords dynamically?
Many Thanks

It looks like you can only extended connection managers for data flow sources.
Is there anyway to develop a custom connection manager for the SQL destination in the data flow destinations?
I can€™t use hardcoded connection strings. I can€™t use configurations because they are not encrypted. I already have managed code that will give the corrected connection string. I already have a custom connection manager that I use from the data flow sources. I just need one for data flow destinations but I can€™t see a way to extend into the OLE DB?

Hi,
I'm trying to use an OLE DB connection manager from inside a custom log provider, but can't get the code to work - I get an exception "A first chance exception of type 'System.InvalidCastException' occurred in SSEALogProvider.dll" on the last line of the code below.
I know the connection is OLE DB from looking at .CreationName.
I've tried both with & without ToConnectionManager90(), but appearently not in the right way, both cases gives the same exception.
Any tips on what I'm missing? All the examples I've seen are either creating (instead of using) connection managers, or are file based connection managers. Any and all help much appreciated!
Thanks/Kristian
if (this.ConfigString.Length == 0 || connections.Contains(ConfigString) == false ||
connections[ConfigString].CreationName != "OLEDB")
{
infoEvents.FireError(0, "SSEALogProvider", "The ConnectionManager " + ConfigString + " specified in the ConfigString property cannot be found in the collection, or is of the wrong type (expected CreationName='OLEDB'.)", "", 0);
return Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure;
}
else
[...]
public override void OpenLog()
{
if (!connections.Contains(this.ConfigString))
throw new Exception("The ConnectionManager " + this.ConfigString + " does not exist in the Connections collection.");
ConnectionManager connectionManager = connections[ConfigString];
IDTSConnectionManager90 connectionManager90 = DtsConvert.ToConnectionManager90(connectionManager);
object connObj = connectionManager90.AcquireConnection(null);
//ConnectionManagerOleDb connectionManagerOleDb = (ConnectionManagerOleDb)(connectionManager.InnerObject);
//object connObj = connectionManagerOleDb.AcquireConnection(null);
if (connObj == null)
{
events.FireError(0, "SSEALogProvider", "Could not connect to the log database with connection string " + ConfigString + ".", "", 0);
return;
}
// Exception on next line: "A first chance exception of type 'System.InvalidCastException' occurred in SSEALogProvider.dll"
OleDbConnection oledbConnection = (OleDbConnection)connObj;

If I have 6-8 queries running in parallel, Whether having a Single connection Manager (for the same source) for all the Extract performs faster or having Distinct Connection Manager for each of the extract performs faster ?

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

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.
Suggestions?

Ok, I have the following table
CREATE TABLE employees (
employee_number char(6) NOT NULL
, known_as char(20)
, surname char(20)
, job_title char(20)
, manager_number char(6) NULL
, unique_identifier char(6) NOT NULL PRIMARY KEY
)
--unique_identifier is in the format 000123456789
Now I have a conundrum when trying to create organization charts in Visio, so I figured I'd try reproduce the format that a bunch of walkthroughs suggest, which is with the first column being an int identity(1,1) column as the employeeID with the managerID being an int column also, referencing the employeeID.
Hope I've not lost you just yet ;)
So here's what I figured - create a new table with the new integer columns, slap my current data into it and then update the managerID as necessary...
Except I can't work out the update statement for this!
CREATE TABLE gvVisioTest (
employeeID int identity(1,1)
, employee_number char(6)
, job_title char(40)
, department_reference char(10)
, managerID int
, manager_number char(6)
)
GO
INSERT INTO gvVisioTest(employee_number, job_title, department_reference, manager_number)
SELECT employee_number, job_title, department_reference, manager_number
FROM employees
GO
--Update managerID with relevant employeeID
GO
DROP TABLE gvVisioTest
Any ideas?
Oh and this is legacy so the design is flawed, modified over time (the manager field is a bodge put in 5 years ago), so yeah unfortunately I have to work with what I've got :(

Dear Experts,
I'm working for an ERP company, for our product, there are around 2000 tables. in each table, we are using 10 extra columns for our future use. all these are using nvarchar(50) datatype.
almost 95% of the columns in these are not in use almost. those are having null value and in some columns, the values are like 0,1...
is this affects the performance?
please spare your valuble time
thank you very much

Hello,
I have a table which resides on a diff.filegroup.
The space allocated is 7700MB.
Now ehen I use sp_spaceused 'table_name' to see how much space is left it's giving me data as
rows reserved data index Unused
at 1000hrs 629879 6777904 5068344 8 1709552
After an hour 637537 6780336 5070800 8 1709528
After 2hours 643883 6782560 5072904 0 1709656
After 2.5hrs 646887 6783584 5073920 0 KB 1709664 kb
after 3hrs 647239 6783712 5074056 0 KB 1709656 K
If you note rows are increasing,so is the reserved place and data but unused is also increasing.I think it should come down.
What behavior is this?How can I find out how much space is left in this table residing on diff.file group?
TIA

I would like to verify that we do not have any unused login ids. I know I can turn on auditing for successful login attempta and either manually check the logs or write some type of findstring code to capture successful login attempts and then for each success, remove the id from a master list, but I was wondering if there may be a simpler approach. Any thoughts?
Thanks, Dave

I have a 3rd party developed app which has over 42000 data fields in 1200 tables. It is a heavy transaction type app. Of these fields over 10,000 are null for every record. SOme of their homegrown references these fields (and this can be removed), and in many instances many of the fields are not referenced at all. My opinion is that these extra fields are adding a heavy overhead to updates, inserts etc to the server. Any disagreements?

I wrote simple script to check space used by tables:
CREATE TABLE #SpaceUsed(
TableName NVARCHAR(128),
NoOfRows INT,
Reserved NVARCHAR(18),
Data NVARCHAR(18),
Index_Size NVARCHAR(18),
Unused NVARCHAR(18)
)
GO
sp_msforeachtable "INSERT INTO #SpaceUsed EXEC sp_spaceused '?'"
SELECT * FROM #SpaceUsed
SELECT
CAST(Sum(CAST(Replace(Reserved,' KB','') AS INT)) AS NVARCHAR) + ' KB' AS TotalReserved,
CAST(Sum(CAST(Replace(Data,' KB','') AS INT)) AS NVARCHAR) + ' KB' AS TotalData,
CAST(Sum(CAST(Replace(Index_Size,' KB','') AS INT)) AS NVARCHAR) + ' KB' AS TotalIndex_Size,
CAST(Sum(CAST(Replace(Unused,' KB','') AS INT)) AS NVARCHAR) + ' KB' AS TotalUnused
FROM #SpaceUsed
DROP TABLE #SpaceUsed
and one of results looks strange to me:
TableName NoOfRows Reserved Data Index_Size Unused
-------------------------------------------------------------------------------------------------------------------------------- ----------- ------------------ ------------------ ------------------ ------------------
T_TableXX 50081 38024 KB 37432 KB 640 KB -48 KB
Anyone know reason of such result (negative value of unused space)?
