Network Timeout To Mirror Causes Primary To Deny Connections

Nov 1, 2006

We've had two instances now where when there is a network connection timeout to the mirror from the primary, the primary db server goes to 100% utilization and refuses all connections.

The first time we had to reboot the primary, the 2nd time mirroring picked up again 10 minutes later.

There are two dbs being mirrored, one is 15gig, the other 4gig. Both boxes are running SQL2005 64 bit and Win 2003 64bit.

This happened at 6am and typically there shouldn't be a lot of traffic at that time but here are the error messages in the SQL log below.

We are going to try and move db communications to a separate network and network card - but this looks like either a bug in mirroring or a configuration problem on our end - though it works just fine other times.

Any thoughts/suggestions would be greatly appreciated.

Thanks!

Mark

How To Forcing The Mirror Communication To A Private Network?

Jun 16, 2007

SQL 2005 Standard x64 Service Pack 2

Windows 2003 R2 X64 service pack 2



The principle, partner and witnesss have two NICs each (NIC1 and NIC2). I want them to communicate in NIC2 for sending logs and establishing quorum. This will happen in their own private network (say 192.168.1.0/24). The NIC1 in each server will be available for client communication. The domain and clients are in the network (say 10.1.1.0/24).



I am using the same domain account as SQL server service account in all three servers.



How can I do this?



Thanks

Database Mirroring. Asp Application (IIS 6.0) Does't Forward Connections To Mirror Server

Mar 28, 2007

Hi!

I have setup a database mirroring session without witness - ServerA is the principal, ServerB is the mirror,. Each SQL Server instance is hosted on its own machine on sql2005 EE SP2. The mirroring is working correctly. If I submit to server ServerA command:

ALTER DATABASE MYDBNAME SET PARTNER FAILOVER

, ServerB becomes the principal, it means that mirroring works correctly.

My issue is with the SQL Native Client and a front-end ASP application (actually IIS 6.0 site) that needs to make use of this database. I have setup my front-end application to use SQL Native Client and specified the failover server in connection string. Here is the connection string that I am using :

PROVIDER=SQLNCLI.1;Server=ServerA,1433;Failover Partner=ServerB,1433;Database=MYDBNAME;Network=dbmssocn;Integrated Security=SSPI;

Everything works perfectly on my front-end application when ServerA is the principal. If I execute on server ServerA command:

ALTER DATABASE MYDBNAME SET PARTNER FAILOVER

, ServerB becomes the principal, and the failover occurs correctly on the database side. The problem is that my front-end application is not able to query the database on ServerB. The error appears:

Microsoft SQL Native Client error '80004005'

Cannot open database "MYDBNAME" requested by the login. The login failed.

This behavior my appication till I unload IIS 6.0 pool application. After that my front-end application becomes work correctly with ServerB.

When I swap server, I execute on server ServerB command:

ALTER DATABASE MYDBNAME SET PARTNER FAILOVER,

my IIS 6.0 application automaticly turn back to ServerA without any action on my side.

I am using SQL Native Client last version http://download.microsoft.com/download/2/7/c/27c60d49-6dbe-423e-9a9e-1c873f269484/sqlncli.msi (issued in February 2007). Has anyone experienced this issue? I'm thinking that it's a problem in the SQL Native client

SQL Express && Network Connections

Jun 21, 2006

This has been driving me crazy for weeks and I can't seem to find any info on it... Here is the scenario:
I've developed an intranet using ASP.NET 2 and SQL Express.  I have the site running on my local development computer and also the production server (Windows Server 2003 running SQL Express).
Fully functional connection string for database running on local development computer and running on production server:
<add name="ASPNETDBConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename='|DataDirectory|ASPNETDB.MDF';Integrated Security=True;User Instance=True;Connect Timeout=30"     providerName="System.Data.SqlClient" />
Once I roll the site out, I want to be able to develop (to some degree) against the production database. But when changing my connection string to point to the production server from my development computer...
    <add name="ASPNETDBConnectionString" connectionString="Data Source=LancelotSQLEXPRESS;Database='D:OfficenetApp_DataASPNETDB.MDF';Integrated Security=True;User Instance=True;Connect Timeout=30;" providerName="System.Data.SqlClient" />
...I get the following error:
User does not have permission to perform this action.
I've found some documentation about not using the "User Instance=True;" command but without that I get:
Cannot open database "D:OfficenetApp_DataASPNETDB.MDF" requested by the login. The login failed.Login failed for user 'WITTEGregL'.
In regular SQL Server, (not Express), I just change the connection string to work against the Local or Production database and it's really easy.  I just can't figure out the trick to do the same kind of thing using SQL Express.
Can someone clear this up for me?

Timeout Errors, And General Network Error Messages

Sep 5, 2006

Hi

We have a VB6 app, with SQL2005 database, SQLOLEDB driver


We have it installed at many clients and normally works fine.


We've migrated one client from SQL2000 to SQL2005 and had to move the database to a new machine.

It's now running SQLExpress sp1, on a Win XP sp2 machine

The clients now frequently get either

a) SQL timeouts
or
b) Runtime Error€™2147467259 (80004005)
[DBNETLIB][Connection Read(recv()).]General network error. Check your network document
Errors
I suspect it is something to do with connections not be released (even though we explicitely free them in the app).
Where do I look ?
Thanks

Maximum Concurrency Of 2 For Outbound Network Connections From CLR-stored Procedure?

Jul 18, 2007

Hi



I've implemented an SQL-CLR stored procedure which makes an HTTP connection using the WebClient class to a server where the processing on the web server takes 10 seconds.



If I fire off a bunch of requests to the stored procedure, e.g. 80 in 1 second I noticed that SQL Server 2005 (Express Edition) only allows 2 concurrent network connections at a time.



I can confirm this by looking at the timing of the results when they come back, basically I get 2 results every 10 seconds and by doing a 'netstat -a' on the web server I notice that there are never more than 2 HTTP connections from the SQL Server at a time.



Is this some sort of sheduling policy in terms of the number of concurrent external network accesses allowed by CLR objects running in SQL Server? Or some side effect of the way the WebClient class blocks in terms of waiting for a network response?



I was expecting all 80 of the requests to block waiting on a network response almost immediately and then for all 80 of them to pretty much complete and return 10-11 seconds later.



[Microsoft.SqlServer.Server.SqlProcedure]

public static int CreditAuthorisation(string Name, decimal Amount)

{

WebClient client = new WebClient();

string result = client.DownloadString("http://someserver/Test.aspx");

return int.Parse(result);

}



Cheers

Problems Of Remote Connections For Creating A SQLCLR Project In SQL Server Express-ADO.NET 2.0-VB 2005 Express Via Network/LAN

Sep 19, 2007

Hi all,

In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.

2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:

Mirror And Witness Connection In A Disconnected State Immediately After Adding Witness Server To Mirror Session.

Jan 31, 2008


After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.

The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.

ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'

After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.

The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.

Any idea's why the state between Mirror and Witness Connection remains Disconnected?

Thanks,

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. (provider: SQL Network Interfa

Dec 10, 2007

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.

[DBNETLIB][ConnectionRead (recv()).]General Network Error. Check Your Network Documen

Sep 30, 2004

Hello all,

We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.

This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.

We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:

<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>

Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.

The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.

Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.

Should have 330 rows if it works right.

[DBNETLIB][ConnetionWrite (WrapperWrite()).]General Network Error. Check Your Network

May 19, 2004

Hi
While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears.
Does somebody knows why?

I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.

Thanks!!
Regards

ASP.Net 1.1 With SQL 2005 : General Network Error. Check Your Network Documentation

Oct 4, 2007

Hi Every one,

I am using .Net 1.1 for my web application.

And my database server is SQL Server 2005.

My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,

General Network Error. Check your network documentation


I have also searched many articles and tried following solutions but nothing working

- connectiontimeout = 0, max pool size = 7500/100, pooling = false

- SSL disabling enforce security false as mentioned in microsoft kb article.

And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)

Can any one please help me to solve this error?

With Regards,

Timeout Expired. The Timeout Period Elapsed Prior To Obtaining A Connection From The Pool.

Feb 5, 2004

Ok bear with me here :). I have a server that is getting about 1000000 hits per day with about 10,000 unique vistors. For the past 2 months I have been revamping my code trying to deal with the increase in traffic. I have 2 boxes, one for the website, and one for the SQL. They are connected through a secure backlink so that I dont have to worry about encrypting the data. So the problem started when I updated the MDAC components a few weeks ago. I started getting these freaking timeout errors, they are up to about 1000 errors per hour. I have been monitoring the connection pooling using the system monitor for about a week and have noticed that I am not maxing out the pooling but I am still dropping connections. I went into the web.config and turned my max connections to 1000. Unfortunately this didn't even put a dent in the problem. It doesn't matter if I have 12 or 212 open connections it still drops them. I am at my wits end with trying to debug this problem. I am wondering if anyone else has had similiar problems recently. Also on a side note I have checked all my connections to make sure that I am closing them. Not only do I close my datareaders but I also set them to nothing. In addition to closing and reseting my datareaders I am also disposing and reseting my connection objects as well as closing them. Any help would be greatly appreciated.

Thanks,
Daniel Christoffersen

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

Dec 28, 2006

Hey,
From time to time i get this error "Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding." so I tried to change the connection string by adding thie following "Connect Timeout=200; pooling='true'; Max Pool Size=200" but still it is giving the same error! so why is this happening ? and what can I do!
btw the timeout expired happens when a stored procedure is executed at the Fill method !
Thank you in advance

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

Mar 1, 2007

Hi All,
I am facing a problem in SQL Server 2005 and the .NET Environment. I have an SP, which will return me the result within fraction of second when i execute it in SQL Server Management studio. But randomly (Frequently), its giving timeout when i execute it from .NET Envirnment.
If i execute it at that same time in Management studio, i am not getting the error. But getting the Timeout when i execute it in the Server Explorere of VS 2005 or in the Application which uses it.
Can any one figure out the solution.

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

Jul 15, 2007

Hi!
 I am having a problem with my windows app in VB.net. I am just trying to do a very simple select command to retrieve some data. I am using a hosting server with a VPN.
When i click on the button it keeps giving me the error above. When I use server management express to do the same query it works fine and relatively fast.
So I have tried setting the CommandTimeout to 120 but when it stops, the debugger shows that the value of the COmmandTimeout is 30, although it stops after about 15 secs.
I am really lost and would need some help please! Find my code underneath.
 Private Sub RetrieveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RetrieveButton.Click

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding

Feb 1, 2008

HI,
 
I am getting this error on web server. My Appication is working fine on my Local Network where DB server and web server are on different machine. But getting TimeOut on web server. I tested the query on Query Analyzer it takes hardly 3 sec (Max) to execute. There is only Select query and total number of records are around 2100 which is not a big data.
I have used Connect Timeout = 180  in connection string which is also not effective. 
please tell me how can I handle this exception.

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

Mar 7, 2008

We've been having timeout problems.
In our development environment we have IIS and SQL Server 2005 both running on the same box. We use VWD or our dev server's IIS to run the apps.
What happens is the database stops responding to our web applications and we continue to get the timeout error. I can still execute queries from Management Studio but all of the web apps all timeout.
Then, the only was we can get the database to start responding again is if we restart the SQL Server service.
Any ideas as to why the database would stop responding to all of the web apps but not Management Studio? It tends to happen a couple times a day when we are developing. Only the other developer and myself use the DEV environment.

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

May 12, 2008

 Hi, I keep getting this error. I have a query that takes 47 seconds when I run it in SQL Server 2005. My connection string looks like this:connectionString="Server=server; Database=db; Pooling = true; Connect Timeout=60; Max Pool Size=300;I understand that Connect Timeout 60 = 60 minutes. Is there any other place where a timeout can be set in an ASP.NET 2.0 application?Thanks for any ideas.

Timeout Expired. The Timeout Period Elapsed Prior To Completion Of The Operation Or The Server Is Not Responding.

Jan 3, 2004

"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

Environment:-
Framework 1.1
DB:SQL Server 2000 (SQL Provider)
OS:Windows 2000
Language: VB.NET

I'm trying to do mass inserts/updates. Using Transactions. The table hierarchy contains 3 levels (TL1, TL2, and TL3):
Here is what I'm trying to accomplish:

1) Start Begin Transaction (in desperation, I've tried all the isolation levels- I was hoping ReadUncommitted would work!)
2) Do an Insert/Update in table TL1 (this works).
3) Grab the ID from step 2 and do a SELECT on table TL2 to determine if I need to an UPDATE or INSERT.

Since I'd be inserting 3 rows into table TL2 (for a particular parent ID with different types), the first SELECT (on TL2) works and then I'm able to do an INSERT into TL2. The transaction is still alive. Now, I try to do a SELECT on table TL2 to see if a record exists for this type and this is when I get the exception "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

My guess is that I have a LOCK on the table TL2 (from the first SELECT), which seems to be causing the problem.

Note:
The INSERTs and UPDATEs are done by executing stored procs.
For the SELECTS, I'm using a different connection (from the one which the transaction is using) and close it after the SELECT is executed.
