We have two Server 2005 boxes and one Sever 2000.
About 3 months ago we started experiencing random database connection drops.
These were manifested by exception errors in database applictions that had worked fine for years.
The exception error stated that no db connection exists even though it had been fine a moment ago.
Server Management Studio also started giving the error:
"Msg 10054, Level 20, State 0, Line 0
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)"
All three servers randomly lose connections.
All our clients randomly lose connections.
I don't think its a network problem because only db applications seem to be affected.
Also, a client can be running two db applications. Application A will fail, while B marches on unaffected.
Does anyone have any ideas what could be causing this?
I would like a way to monitor the SQL Server connections but am not sure how.
sys.sysprocesses seems to show all the connections, but it doesn't show when a connection is being terminated.
SQL Server log shows no connection messages.
I have posted this in the SQL Server Data Access forum but wondered if this was a better location.

for some reason my Sql Server has stopped and i am not able to restart it at all, do i have to reinstall the complete SQl Software or is there ne way i can start the MSSQL Server
We recently converted an application from accecc97 to access2003. We used to have 2 databases : 1 with all and only the data (axelD.mbd), 1 with all the forms, query's, ... (axelP.mdb)
We replaced the data (axelD.mdb) with an MSDE database, through UPSIZE and so on. That all worked fine. This database is placed on the dataserver (DATA1), the converted programm is on the FRONT2 server (FRONT1 stil usess access97 until conversion is totally ready).
We are able to connect to the MSDE by using ADODB recordsets. We are also perfect able to link the MSDEtables in our axelP.mbd database
We started to test some heavier parts of our application and started to get the following error:
"ERROR 3151" "ODBC--connection to 'JOROSOFT' failed"
Nothing more.
This happened in a quite complex routine, whitch updates a lot of records, several times and so on. We could reproduce the same error when executing the following code:
Public Function TestBestellingen() Dim sql As String Dim intervalset As DAO.Recordset Dim planset As DAO.Recordset Dim tellerke
x = Opendatabases() tellerke = 0 sql = "Select bestelnummer from vkpbestellijn where bestelnummer > 100000" Set planset = Db_AxelP.OpenRecordset(sql, dbOpenDynaset) Do While Not planset.EOF tellerke = tellerke + 1 Debug.Print tellerke & " - " & planset!Bestelnummer & " --> " & IsKlantStof(planset!Bestelnummer) planset.MoveNext Loop End Function
Function IsKlantStof(p_bestelnummer) Dim sql As String, rst As DAO.Recordset Dim hulp_klantstof As Boolean
hulp_klantstof = False x = Opendatabases() sql = "select klantstof from vkpbestellijn where bestelnummer = " & p_bestelnummer Set rst = Db_AxelP.OpenRecordset(sql, dbOpenSnapshot)
With rst Do While Not .EOF If !KlantStof = True Then hulp_klantstof = True .MoveLast End If .MoveNext Loop End With rst.Close Set rst = Nothing IsKlantStof = hulp_klantstof End Function
Function Opendatabases() If Db_AxelP Is Nothing Then Set Db_AxelP = DBEngine(0)(0) End If End Function I know this code makes no sence in a real-time environment, but it was to reproduce the error. This code basically runs trough a 30.000 records and does a little check for certain fields After 1981 records we get the above error. (sometimes after 1979 or 1980 or 1982 records)
"vkpbestellijn" is a table that is linked in the AxelP.mdb trough an ODBC connection. We get the same error (and after 1981 times) if I change the where to a totally other range of "bestelnummer"
I have installed the latest patches of Jet 4.0, MSDE-server, ...
I've been searching the internet for abour 3 days now, and just cant even find the smallest clue what could make this happen.
I hope someone here has an idea. If you need more details, just ask.
tia, Axel.
P.S. I'm from Belgium, so my english aint "correct to the point".
We are running an ASP application. That is fairly simple.It selects from one table (15.000 records), and updates into another table.But when we execute the ASP script, it reports the following error, aftercompleting between 70%-80%. This varies each time it runs"Microsoft OLE DB Provider for SQL Server error '80004005'[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or accessdenied.

I have a strange issue when scheduling SSIS Job.
When I schedule it, I set the owner as the domain administrator. The scheduled job can be run manually without any problem. The scheduled job run automatically at scheduled time wihtout problem.
But , for an unknow reason, after some cycle, the job failed with the following error : The job failed. The owner () of <name of the job> does not have server access
As you can see, the owner name is blank.
If I look to the job settings : the owner is still the domain administrator. If I try to run it manually, the job fails with the same error. now if I just rename the job name from <name of the job> to <name of the job2> then all problems are solved. If we let the job failing everyday, sometimes, it starts again to work properly. We have this issue on 2 jobs.
If anyone has faced this issue : thank you for advise.
Excuse me for the 'noobish' question but it seems in my mining models, i am 'loosing' input variables. I am using the Microsoft Decision Tree algorithm and eventhough i have set 4 variables as 'input' and all 4 of them are in my mining structure, the model is using only 3. That 4th variable is also missing from the dependency network graph. Can anyone help me solve this problem?
I'm getting a connection and then loosing my connection upon refreshing the browser with this script connecting to MSSQL using php, when trying the following:
PHP Code:
$connection = mssql_connect("127.0.0.1","test","") or die("Could not connect mssql db on " .$config['dbhost']);
mssql_select_db("dbName") or die("Could not select database " ."dbName");
Are their other ways to see more error handling in connecting to MSSQL
I'm using varchar as a datatype and my leading zeros are chopped-off once ther data reaches my Stored Proc. The table will allow me to store the values with leading zeros if I enter them manually, but I cannot insert them via ASP/StoredProc.
Hi,I'm having an issue where users are copying and pasting text from word documents. The formatting of certain special characters such as mswrods curly ' is fine until the string is inserted in to the db (sql2000 varchar field). I'm using asp.net 2.Any ideas on this one?Ta Dan
I need to copy the table structures from my production database to development database but not loose the data in developement. Is there a way to achive this by creating some scripts. thanks
There is a bug in SQL-2005/2008 Replication system, which may break data integrity, when using @@IDENTITY function to update FOREIGN KEY of some table.
When Merge replication is set up, and there is a table article with IDENTITY column in it, after inserting a new row in the table a value of @@IDENTITY function does not actually shows just inserted row's identity value.
This issue also generated when performing inserts via ADO.
When loading a table in a data flow from a text file that contains non-null float values, I am seeing erratic and inconsistent results. I am presently using SQL Server Destination in a data flow.
- With low volumnes of data, less that 50,000 rows, no problems
- But with higher volumnes, 2,000,000+ rows, I get different results depending on how I run the package. If I run is directly (right-click and click on Execute), I get the expected result.
But if I use SQL Server Agent to run the package, half of the values are lost and nulls are loaded instead. I have inspected the into text file and there are few rows with null for the column.
I have a script and on one of the tables I keep loosing the mapping of the last 4 fields. If I go into the task it will ask me if I want it to automatically fix it and I say yes and remap fields but when I run it it bombs and comes back and when I go back into it it tells me there is a problem with same fields. It also rearanges the order and puts these fields last.
I have tried deleting and redoing the transformation only to have the same thing happen. Almost seems like a bug in software. I have seen this before but usually when I fix it it does not return.
i'm using a "data conversion" object to convert a numeric field to a string just before i save the record set to the database.
the problem is when this numeric field is > 0 it looses the precision on its decimal value.
example, if numeric value is 0.32
after converting this to a string, the new value will be : .32
it's lost the 0 infront of it. i can't do this converion in the query level because it's a derived field, so i need to convert it to a string before stroing it.
when converting to string i'm using the code page 1252 (ANSI - Latin I). i also tried with unicode string both looses this 0 infront.
I created a custom transform that has a custom interface and is a wizard that uses a web service. It creates custom properties and output columns on the fly. I set the dialog result to Ok and close at the end of the steps. The transform then has the custom fields and output columns I created in the wizard. I've verified this by right clicking on the transform and going to the advanced editor. If I then immediately run the package, the custom fields don't exist in the CustomPropertiesCollection. If I close the package and reopen it, the properties now are gone. If I then go through the wizard again, thus recreating the properties, they stay and don't disappear. The quickest way to get a working transform is to add it to my data flow then save, close and reopen the package and then go through the wizard. Just saving after I add the transform does not help.
Does anyone know what might be causing this very strange problem?
I experienced this problems on both Windows Mobile 2003 SE and Windows Mobile 5.0.
Its native development (c++, oledb, atl and mfc).
It's quite simple to reproduce...
1. open a database
2. open a rowset on table A (whatever, valid of course and with both IOpenRowset and ICommandText), read datas and close rowset
3. power off
4. power on
5. try step 2 with another table (failed on openrowset with error 0x80004005) or try table A (sometimes working because of cached memory, sometims failed on Read Datas).
6. being stuck ;-)
Our work-around was, in case we loose our connection (identified by error 0x80004005 on openrowset), we close it and re-open database... ugly for sure, but working.
What I'm looking now is to use some kind of "detection method" like what people in .Net develoment are using "if ConnectionState.Open <> ...) for reopening my database only on demand...
Hi there, Here we have got a asp.net application that was developed when database was sitting on SQL server 6.5. Now client has moved all of their databases to SQL server 2000. When the database was on 6.5 the previous development team has used oledb connections all over. As the databases have been moved to SQL server 2000 now i am in process of changing the database connection part. As part of the process i have a login authorization code. Private Function Authenticate(ByVal username As String, ByVal password As String, ByRef results As NorisSetupLib.AuthorizationResult) As Boolean Dim conn As IDbConnection = GetConnection() Try Dim cmd As IDbCommand = conn.CreateCommand() Dim sql As String = "EDSConfirmUpdate" '"EDSConfirmUpdate""PswdConfirmation" 'Dim cmd As SqlCommand = New SqlCommand("sql", conn)
cmd.CommandText = sql cmd.CommandType = CommandType.StoredProcedure NorisHelpers.DBHelpers.AddParam(cmd, "@logon", username) NorisHelpers.DBHelpers.AddParam(cmd, "@password", password) conn.Open() 'Get string for return values Dim ReturnValue As String = cmd.ExecuteScalar.ToString 'Split string into array Dim Values() As String = ReturnValue.Split(";~".ToCharArray) 'If the return code is CONTINUE, all is well. Otherwise, collect the 'reason why the result failed and let the user know If Values(0) = "CONTINUE" Then Return True Else results.Result = Values(0) 'Make sure there is a message being returned If Values.Length > 1 Then results.Message = Values(2) End If Return False End If Catch ex As Exception Throw ex Finally If (Not conn Is Nothing AndAlso conn.State = ConnectionState.Open) Then conn.Close() End If End Try End Function ''' ----------------------------------------------------------------------------- ''' <summary> ''' Getting the Connection from the config file ''' </summary> ''' <returns>A connection object</returns> ''' <remarks> ''' This is the same for all of the data classes.

But in the authenticate method above at the line Dim ReturnValue As String = cmd.ExecuteScalar.ToString
for some reason its throwing the below error. Run-time exception thrown : System.Data.SqlClient.SqlException - @password is not a parameter for procedure EDSConfirmUpdate. If i comment out the Dim conn As IDbConnection = New System.Data.SqlClient.SqlConnection and uncomment the .net oledb provider, Dim conn As IDbConnection = New System.Data.OleDb.OleDbConnection then it works fine. I also have changed the webconfig file as below. <!--<add key="Common" value='User ID=**secret**;pwd=**secret**;Data Source="ESMALLDB2K";Initial Catalog=cj_common;Auto Translate=True;Persist Security Info=False;Provider="SQLOLEDB.1";' />--> <add key="Common" value='User ID=**secret**;pwd=**secret**;Data Source="ESMALLDB2K";Initial Catalog=cj_common;' />
My site works fine in VWD2008 express, but I get this error when I try to use it on my live website. An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration. Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"... The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.
I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

I have created a simple package that uses a sql command to pull data from an oracle database and inserts the data into a sql 2005 table. Some of the data fields that i am pulling from contain two digits after the decimal point, however this data is lost when it gets into sql. I have even tried putting the data into a flat file, and still the data is lost.
In the package I have a ole db source connection which is the oracle database and when i do the preview i see all the data I need. I am very confused and tried a number of things to get the data into sql, but none work. Any ideas would be very helpful.

I am trying to connect to Microsoft SQL Server 7.0 - Standard Edition through Query Analyzer. I am doing multiple query windows in order to have multiple connections to SQL Server. I cannot seem to get anymore connections than 10. I have increased the licenses to 20 and I have tried to disable and stop the License Service. I have rebooted the server after making these changes and neither seems to work, I cannot establish more than 10 connections. Can somebody help me? Thank You.
I need to put a script together that would tell me how many connections to SQL Server there are at any given time. Which table would store this info? Thanks.
Hi Guys need your expert advise on this. in my previous company in our application we used to have 1 sql server connection open all the time to access database .
in current company ,framework does it differently like opening connection to database only when needed and closing it straight away.when you look at profiler when doing multiple things in our app one will see many connections opened by our application.
my question is which approach is good for performace ? Thanks for advise.
I have to install an application on 5 different client machines. I have 1 Server machine. As of now, what is happening is, only 2 of the client machines are being able to connect to the Server Machine.i.e. only 2 client machines are detecting the server. The other machines are not even registering the server.
Let me know if there is any property or setting taht needs to be tweaked for this.
