Connection Lockout

Oct 24, 1999

I have a custom application running against sql7 that has twice "locked up" sql7. The locked up symptom is that sql 7 will not allow any connections,
even from enterprise manager (server xxxxx is not responding........). The application returns an error that says the
"xxxxx" database is not available, using master instead. A look at the NT event log and the sql7 log provide no help. The OS is running fine and
existing connections (by the application) are still allowing database writes. How do trap what is causing sql7 to stop responding to connection
requests. I am presently starting and stopping the mssql service to get things running, but I really need a root cause. Any troubleshooting tips for
this would be greatly appreciated. Thanks in advance!

Transaction Lockout Of Reads

Aug 28, 2006

Hi,

I have been seeing a basic scenario of a write transaction appearing to unexpectedly lock-out reading.

The database has isolation set to "READ COMMITTED".

The scenario is:

1.) Start a transaction (for doing a write)

2.) Do a read before the transaction (for doing the write) is committed (e.g. sqlCommand2.ExecuteReader()).

--> the code will appear to lock-up (then time out).

I see the same behavior if I step through the "write" code with the debugger (to a point after the transaction is started, but before it is committed), and run a "SELECT * FROM" type query from Microsoft SqlServer Management Studio.

Following is the code sample demonstates the issue.

Thoughts on how to resolve the issue (to let me do "read committed" reading of the database table)?

Thanks!

Andy







Module Transaction

Sub Main()

Dim exception1 As Exception

Try

' Create/Open Database Connection

Dim sqlConnection1 As New System.Data.SqlClient.SqlConnection("Server=GRB-AB;Database=Transaction;Trusted_Connection=True;")

sqlConnection1.Open()

' Start transaction

Dim sqlTransaction1 As System.Data.SqlClient.SqlTransaction = sqlConnection1.BeginTransaction()

' Set Parent record

Dim sqlCommand1 As New System.Data.SqlClient.SqlCommand("INSERT INTO Parent (Name) VALUES ('ParentValue');", sqlConnection1)

sqlCommand1.Transaction = sqlTransaction1

sqlCommand1.ExecuteNonQuery()

' Get Id from parent record (note: this code assumes the table was empty when this program starts)

sqlCommand1 = New System.Data.SqlClient.SqlCommand("SELECT Id FROM Parent;", sqlConnection1)

sqlCommand1.Transaction = sqlTransaction1

Dim parentId As Integer = CType(sqlCommand1.ExecuteScalar(), Integer)



'

' Do reading test to test concurrently reading table being written to

'

' Create/Open Database Connection for reading test

Dim sqlConnection2 As New System.Data.SqlClient.SqlConnection("Server=GRB-AB;Database=Transaction;Trusted_Connection=True;")

sqlConnection2.Open()

Dim sqlCommand2 As New System.Data.SqlClient.SqlCommand("SELECT Id FROM Parent;", sqlConnection2)

sqlCommand2.ExecuteReader()

Dim i As Integer

While (sqlCommand2.ExecuteReader.Read = True) ' <===== LOCKS UP HERE **************

i = i + 1

End While

'

' End reading test

'



' Set child record

sqlCommand1 = New System.Data.SqlClient.SqlCommand( _

"INSERT INTO Child (Name, ParentId) VALUES ('ChildValue', " & parentId.ToString & ");", sqlConnection1)

sqlCommand1.Transaction = sqlTransaction1

sqlCommand1.ExecuteScalar()

' Either 1.) commit transaction OR 2.) rollback transaction

Dim test As Boolean = False

If test = False Then

sqlTransaction1.Commit()

Else

sqlTransaction1.Rollback()

End If

sqlConnection1.Close()

sqlConnection2.Close()

Catch ex As Exception

exception1 = ex

End Try

End Sub

End Module

Account Lockout Problem With Sp_send_dbmail

Sep 1, 2006

I am running this code in a job:

EXEC msdb.[dbo].sp_send_dbmail
@profile_name = 'Blah Blah',
@recipients = 'blah@blah.com',
@subject = 'Server Report 1',
@body = '',
@execute_query_database = 'DBInfo',
@query = 'EXEC dbo.usp_SvrRpt1;',
@query_result_header = 0,
@query_result_width = 300,
--@attach_query_result_as_file = 1,
@query_result_separator = '';
GO

Because I am creating a total of 6 server reports, I alter the subject and query like so:

@subject = 'Server Report X' --where X is replaced with values 1 to 6
@query = 'EXEC dbo.usp_SvrRptX' --where X is replaced with values 1 to 6

I can run 4 reports without any problems. If I run more than 4 reports in the same batch, my network account under Windows 2000 Activity Directory is locked out as if I had erroneously mistyped my password the number of time to meet the lockout requirement - in this case, the number is 3 login tries.

Is this a known problem with Database Mail? If so, is there a fix or workaround?

Thanks,

Neal

Cannot Set Connection Property Of Backup Database Task If Connection String Is Customized In Connection Object

Aug 23, 2006

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.

Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.

Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.

Is this an intrinsic issue?

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,

Connection Strings, Trusted-connection VS Username-password, SQL Server 2005 Express

Mar 9, 2007

All --
Please help.
I have some questions about connection strings.
 
BACKGROUND...

Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
 
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
 
Please advise.
Thank you.

SQL Connection In Vista With Trusted Connection Fails Under Local System Account Until Reboot

Mar 4, 2008

Hi All,

We are using the Windows Task Scheduler as a substitute for the SQL Server Agent, which isn't available in the Express edition. The scheduled task just calls a batch file, which in turn, runs a stored procedure using osql with the -E option for a Trusted Connection.

SQL Server Express has been installed using the defaults, which means the service is running in the "NT AUTHORITYNETWORK SERVICE" account. The scheduled task we create is set to run using the "NT AUTHORITYSYSTEM" account.

Now we find that on Windows Vista (tested using Ultimate Edition) that the scheduled task fails to run the stored procedure until the machine is rebooted the first time after installing SQL Server Express. When I say "fail", I mean that the stored procedure isn't executed. The scheduled task however completes and reports no errors. On Windows XP, we do not run into this problem so I suspect it has something to do with the UAC in Vista?

We further found that after installing SQL Server Express and creating the scheduled task in the "NT AUTHORITYNETWORK SERVICE" account, the scheduled task (and stored procedure) runs fine WITHOUT requiring a reboot.

Can anyone explain why a reboot is needed to get SQL Server Express to run the scheduled task correctly under Windows Vista and the SYSTEM account?

Any help or thoughts greatly appreciated.

Apr 15, 2015

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?

Jdbc Refuses Connection With 'user Not Associated With A Trusted SQL Server Connection' Message

Jul 10, 2007

When using jdbc with IntegratedSecurity, I run into this problem when the machine is not part of a domain & gets its IP address via dhcp. Is this expected behavior or a bug in the jdbc driver.



The SQLServer and client application are installed on the same machine and a local admin is logged in, running the client app.



If I change one of the two parameters mentioned above, the connection can be established leading me to believe this may be intentional for security issues. Am I correct?

ExecuteReader Requires An Open And Available Connection. The Connection's Current State Is Closed.

Apr 26, 2007

I am accessing SQL2005 with C# code using OleDbConnection.



A try and catch block catches the following error once a while between the Open() and Close() of the connection:

ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.



I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.



Any hint would be greatly appreciated.

The AcquireConnection Method Call To The Connection Manager &&<Connection Name&&> Failed With Error Code 0xC020200

Feb 14, 2008

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?

Thanks.

SSPI Handshake Failed With Error Code 0x8009030c While Establishing A Connection With Integrated Security; The Connection Has Be

Mar 7, 2006

Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine. It alwayws works for me but after some minutes the other developer cant work in the application

He got this error

Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]

and When I see the log event after that error, it comes with another error.

SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]

He has IIS5 and me too.

I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.



and in the connection string I have.

<add key="sqlconn" value="Data Source=ESTACION15;Initial Catalog=GescomDefinitiva;Integrated Security=SSPI; Trusted_Connection=true"/>

I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SElevalencia.

Thats strange.

The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.

If you want me to send logs please tellme

Dropped Network Connection Breaks Connection To Local SQL Server

Apr 2, 2008

Let me set the stage of my testbed configuration: On Windows XP SP2, my default connection to the Internet is via wireless express card modem using EV-DO via Verizon Wireless. Let's call this connection A. I also have a traditional wireless network connection (802.11g) that is always enabled. Let's call this connection B. Connection A is always connected during normal business hours. Connection B is not and is often searching for a wireless network to connect to when nothing is in range.



Yesterday, connection B was continuously trying to connect to a wireless network not under my control, meaning that the connection was never established and notification messages continually popped up to complain of this fact. Over time, I've learned to ignore these messages and go on doing my daily work without much thought of the possible implications.




Then, things started to get odd. I was running our application, WebWatchBot, to perform some simple tests of various websites and servers, when I started to get messages from the application that database connectivity was lost, which is a message that pops up to inform the user that the connection is forcibly dropped by SQL Server. After a few moments, the connection to the database was re-established and the message went away. Since I was actually working with SQL Server, I thought it was an anomoly, so I continued on. Then, it happened again. And again. Then, I noticed that the "database connectivity lost" message started to coincide with the wireless connection's (connection B) inability to connect with a wireless network.




Why would this be happening? The database and application are on the same exact computer. The connection to the database is via ODBC drivers over tcp/ip, but why would connection B affect this?





Some added information that may prove useful:



Client side:

The Connection Name 'name' Was Not Found In The Applications Configuration Or The Connection String Is Empty

Jan 18, 2008

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains. I can get into the ASPNETDB database for doing logins , etc but I cant access my database called "PINEmgt".
To try to understand where the problem is located,I built a very simple application without login controls and put on it one Detailform accessing a single line table "Signin". I continually get the error message I got with my real app :"The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty. " There is only one connection string in my app -'PINEMgtConnectionString2'. When I run the app locally on my machine it works. After I move everything to Go Daddy, I get the error message and the following dump"





Line 24: </Fields>
Line 25: </aspetailsView>
Line 26: <aspqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsINEMgtConnectionString2 %>"
Line 27: InsertCommand="INSERT INTO Signup(first_name, last_name, email, customer_id) VALUES (,,,)"
Line 28: SelectCommand="SELECT * FROM [Signup]"></aspqlDataSource>

This is indeed the code from my single page app.

The dump is:




[InvalidOperationException: The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty.]
System.Web.Compilation.ConnectionStringsExpressionBuilder.GetConnectionString(String connectionStringName) +3039085

After Googleing, asking Go Daddy for info (which they dont give) , etc for three weeks, I need serious mental help
in the form of a solution of this problem. Your help with the problem or the name of a good mental health professional in eastern N.C. (maybe both) would be appreciated.

However, in my web.config file I do have a connection named USASH-AS0013. Here is my web.config file (with my user/pwd hidden). Any help would be greatly appreciated.

SQL Server 2008 :: Connection Manager Not Using Connection String Value

Feb 19, 2015

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.

Using One Single-application Connection Vs. One Connection For Every Operation To SQL-Server Via ADO.NET

Aug 11, 2005

Dear members,I'am thinking about the "best" way to connect to my sql-server viaADO.Net (if there is a best way).My application uses the sql-server very intensively. At the momentevery database-operation opens a connection, executes and then closesthe connection.Another way would be to use only a single connection to the database,which is opened when the application starts.What do you think is the better way to get a high performing sqlserver: using one single application connection vs. using oneconnection for every operation?Cheers, Sebastian

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

Cannot Acquire A Managed Connection From The Run-time Connection Manager

SSIS Package Does Not Remember Password (OLE DB Connection + ADO.Net Connection)

Mar 29, 2007

Both the OLE DB Connection and ADO.Net Connection in SSIS Package does not remember password.

Im connecting to a SQL Server 2000 box using its sa password as test.

The SSIS package runs fine when you first set up the connection in bids

The bottom line is that SSIS keeps forgetting the password I feed into
the two Connections that I'm using. I double-click a connection,
type the password in, check "Save my password" and hit "OK" but the
password disappears from there whenever I run the package or
double-click the connection again.



is there any known workaround for this issue as I would like to schedule my SSIS package using a SSIS Step in a SQL Server 2005 Agent job.



the only thing I found when googling this error was link below but the workaround described here is a little harsh

http://www.developersdex.com/sql/message.asp?p=1921&ID=%3C1146409399.447345.7470@j73g2000cwa.googlegroups.com%3E




thanks in advance

Dave



the box SSIS is running on is Windows 2003 Server Standard Edition latest service pack

SQL Server 2005 (no service packs )
