Slow Connection. ASP Page Querying A Linked Server On MSSQL 2005
Dec 28, 2006
Creating a web application. Running a simple query "SELECT username FROM vwCustomer"
vwCustomer is a view built on top of an Access DB which is set up as a linked server. Within SQL Server that view responds immediately. But when I try to access it from an ASP page it takes over 20 seconds to respond.
i'm experiencing an extremely slow connection from a WXPP Sp2 client to a MSSQL2000 running on a W2k server. The client is running a VB6 application that connect with Windows authentication: every form requesting data opens with a long delay at the first launch; next attempts run normally fast.
In the same LAN there are some others identical clients, all running fine.
Every other network activity from that client is ok.
I have installed SQL 2005 (X64) on 64-bit Windows 2003 server (AMD). One of my databases need to connect several Oracle databases on 32 bit servers.
I managed to install Oracle 32 bit Client (was unsuccessful with 64 bit installation) and could set up the odbc (32). But I coul'nt find Oracle under linked servers!
Hi! I have a SQLServer 2005 running om a 64bit cluster. It is used to run a SharePoint 2007 portal. My problem is that the access to the database from the other servers in the farm is very slow.
I made a test program in C# that creates a standard .Net sqlConnection and runs a simple query 100 times. When run on the database server it takes less than a second, but when I run it from the web frontend server it takes 30 seconds. It never fails, it's just slow. The network connection is fast when copying files etc.
I see nothing out of the ordinary in the event log.
Do any of you have an idea what might be the problem or know how I could try to find the problem?
This works. But this is not exactly that what I wanted, because here just my Windows Authentication is used. I want to be able to pass username and password for users that are allowed to access the SQL Server. Here my first confusion begins: I have the option to pass the username and password into the connection string (User Id and Password) or I guess that I can pass them also as parameter 2 and parameter 3. But with trying both of these options I get always a connection error that my specified Username is not be trusted ( I don't know how the message looks in the English version, because I have the german version), but I suppose you know what I mean.
Of course I have to create such accounts in the SQL Server before trying to login with them. I guess that I made something wrong when doing this. I started the Server Manager Studio and there I navigated into the Object Explorer. In the folder Security I created a new account for testing (using SQL Server Authentication). But I cannot use that account for logging in.
I have to admit that I am very new to the SQL Server thing, so I hope someone can help me or can give me hints on what to do better. I am very thankful for every reply...
Hello,I have a Win2K3 Server with SS2005 developers edition. I am working on aWindows XP Pro workstation which has SQL Server 2000 installed as well asthe SQL Native Client. I'm using an MS Access ADP to connect to the serverand for some reason it's extremely slow, even to the point of throwing timeout errors and "can't generate SSPI context" messages. I've hit the MSwebsite and found info on the SSPI error, but none of the items thatgenerate the error apply to my situation. I've tried using the surface areamanager to change the connection to name pipes, name pipes and tcpip etc,but no luck.Is there anything I should be looking at or any known issues that wouldaffect this kind of performance?Thanks!Rick
I am using MSSQL Server 2005 Express Studio and tryig to connetch to the remore server but does not work.
I get this error.
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.
Though I have read like child and made changes according to it.

Still says same error.
I am clueless how to do it.
Do any one know web based mssql editor where i can connect mssql?
How do I specify the Catalogue while querying a linked server?
For exmaple, I have a remote SQL 2000 server as a linked server on my server. I will refer to it as "ServerRemote." I was given access to that server through my Active Directory Domain account and the catalogue 'master' was set as my default database.
Aside from having the admin change my default database, is there a way to query a linked server and specify the catalogue in the query?
Right now I use the following code to query the default catalogue for the linked server: SELECT * FROM ServerRemote...ViewName
I've tried various queryies for a different catalogue but always get a table not found error:
SELECT * FROM ServerRemote..DatabaseName.ViewName or SELECT * FROM ServerRemote.DatabaseName..ViewName or SELECT * FROM ServerRemote.DatabaseName.ViewName all return errors
The stored procedure executes successfully and I can also succesfully DROP the linked server. However when I try to query tables in linked databases using:
SELECT * FROM DB_INTRANET...Employees
I get the following error:
OLE DB provider "SQLNCLI" for linked server "DB_Intranet" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0 TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18452, Level 14, State 1, Line 0 Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
The logins are Windows Authentication and even if I use sp_addlinkedsrvlogin to map logins it still gives me the same error.
I have no problems linking and querying linked Access Databases but can't do it for the SQL Server DBs.
I am trying to connect to a sql 2005 SP2 windows auth server through linked server from a sql 2005 SP2 mixed mode. I am using the "use current users credentials" option for authentication. I am getting the error below. Any thoughts to why this is happening would be appreciated.

I've setup a linked server in SQL 2005 x64 SP2 to retrieve data from OS/400 DB2. When I perform a query on the linked server (select * from openquery(<linkedserver>, "select * from LIB.FILE1'), the following error was returned.

I upgraded a SQL 2000 installation to SQL 2005 this past weekend. Minimal issues overall, but one that did crop up relates to a linked server to an Oracle database. The linked server worked before the upgrade, and stopped working immediately after.
We're running on Windows 2003 x64, latest service pack. The linked server is set up using the MSDAORA provider. The error I'm getting post-upgrade is:
=====================
OLE DB provider "MSDAORA" for linked server "PROD" returned message "ORA-06413: Connection not open.".
Msg 7303, Level 16, State 1, Procedure RDM_GET_REP_LIST_SP, Line 12
Cannot initialize the data source object of OLE DB provider "MSDAORA" for linked server "PROD".
=====================
A tnsping from the server works fine. I've also tried recreating the linked server. Any help would be appreciated. Let me know what other information would be useful.
Hi all, I have a production website at Godaddy and an ASP.net 2.0 page that successfull connects to a SQL 2005 instance provided by Godaddy using SQL authentication(User ID/Password). The Godaddy database has become too small (200MB limit) and the plan is to use the SQL Server 2005 standard edition at my office. In other words, I want to host my own SQL server and keep the front-end at Godaddy. The ASP.net test page at Godaddy generates the basic connection errors when attempting to connect to my SQL server at the office. This error has several variations depending on how the connection string is configured: 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) In this case the connection string is: Data Source=xxx.xxx.xx.xxx,1433; Network Library=DBMSSOCN; Initial Catalog=Test; User ID=xxx; Password=xxx" I've embedded this connection string directly into the ASP.net test page in order to make this page independent of the web.config file. My MS SQL server is on a Small Bussiness Server 2003 with Sharepoint and Remote Workplace running, and this machine is behind a linksys router, and Routing and Remote Access is running in place of windows firewall. I've openned ports TCP 1433 and UDP 1434 on the router and Routing and Remote Access. Telnet xxx.xxx.xxx.xxxx 1433 connects successfull, and the SQL log shows listening on 1433. I don't know if telnet is telling me that there is successful connection to the port on the router, or if it makes it all the way to the SQL server. The SQL server is running the default instance MSSQLSERVER. Locally, I am able to connect using SQL 2005 Studio, and I am able to confirm this activity in the SQL log. Since I've openned port 1433, I also see numerous dictionary attacks in the SQL Log. Based on this, remote connectivity is there. The strange observation is that the SQL log shows no sign of a connection attempt from the ASP.net page. The connection appears to be failing before it reaches the SQL server. I've openned ports in the Linksys router and the NAT/Firewall the same way I've openned them for Sharepoint and Remote Workplace. I also found that when I move the ASP.net test page to another ISP, then the SQL connection that worked from the Godaddy website, is no longer able to connect. An explanation of this would also be very helpful to me. Is there something that needs to be configured to expose the SQL server to ASP.net pages that is different from remote access? Does IIS need to somehow be involved? Is there something in Small Business Server 2003 that could be interferring with ASP.net page requests to the SQL server? Do I need to run my machine as a web server to make this work? Any help with this configuration would be greatly appreciated.
Can I connect from a SQL Server 2005 database to a SQL Server 2000 database, without establishing a linked server connection.
I need to fire a SELECT query on a SQL Server 2000 database, but don't want to add it as a linked server. Is there any way I can do this or its not possible??
I've just moved a website/database application from windows server 2000 and sql server 2000 to windows server 2003 sp2 and SQL 2005 Express SP2. Database intensive pages now take about 40 seconds where before they took 2-3 seconds.
I need to push 40k rows daily to an Oracle database. I am on a Win2k Pro box with the 8.1 client and ADO 2.6 loaded. I've configured the linked server with the Oracle as well as the Microsoft provider and it takes over a minute to push just 24 rows, less than 100 bytes each, at it. Any suggestions?
I've connect some .DBF file to SQL server 7 with linked server option. My table have about 200.000 records. I've tried with ODBC and Jet 4.0 option (found in www.mssqlserver.com) but I've very slow response if I use a "where" in the select instance. In fact I've the response after 10 seconds and during this seconds the processor go to 100%. Does anyone found a most speed way to do this?
I have a linked server set up on my local SQL 2000 instance. I try and run an update against an SQL 2005 database and it take 29 seconds. I checked the execution plan and it says it takes the entire time on the Remote Scan. Is there something I need to do to speed this up? There is an index on the PK that I am searching against.
Hi i have a sql server instance on my system and it is linking into an oracle database on another server. When i run queries against this other server...it takes forever...
However, when i use access, and link the table and run the same query against the oracle database...it runs immediatly.
I am very confused as to why there would be such a performance difference and why sql server would run so slow.
I am wondering if it has something to do with the way i configured the linked server. there are several options that I didn't know what they meant.
collation compatible (not selected) Data access (selected) RPC (not selected) RPC Out (not selected) collation name connection timeout query timeout
I have 2 servers (say MAINSRV e SECSRV) running SQL2000 Standard SP3 on Windows 2000 Advanced within a NT (!) domain and each server is linked to the other.
My problem is that if I run a query returning few dozens of rows like:
SELECT * FROM MAINSRV.DbName.dbo.TblName TBLA WHERE Fieldx = 'anyval'
from a client connected to the SECSRV server, it takes something like 35 minutes to complete, while the same query completes in no time when run on clients connected to MAINSRV.
Even the simplest SELECT Count(*) FROM... takes more than one minute from SECSRV while completing in a fraction of second from MAINSRV.
I tried to change the linked server security options (SQL/Windows), but the remote query remains slow.
There are no locks active on the table, both the servers have almost no load (CPU less than 10%, when tested) and the query returns just a few KBytes, so communication overhead will not be the problem.
Any suggestions will be very appreciated, thank you!!!
Hello can some one explain this to me and give me some advice. I have sqlserver1 and sqlserver2 I have a linked server set up [ipaddress] on both servers. When I pass a variable to the stored proc or the query it takes up to 20 seconds to return 1 row but if I replace my varibles like email='sqlboy@coxnet' and firstname='ted' and lastname='clien' it returns the one row im looking for in about 2 seconds but if I pass email =@email ,fname=@fname,lname=@lname I get the 20 second thing. The query is a stored proc being called from an asp app. I get the same results when I run this in query analyzer.
IF EXISTS (SELECT TOP 1 email FROM [ipaddress].{database}.dbo.{tablename}--server1 WHERE email = @email ) BEGIN set nocount on SELECT TOP 1 email, FIRSTNAME, MIDDLENAME, LASTNAME, TITLE, COMPANYNAME, ADDRESS1, ADDRESS2, CITY, STATE, ZIP, COUNTRY FROM [ipaddress].{database}.dbo.{tablename} --server2 WHERE email in(SELECT EMAIL FROM [ipaddress].{database}.dbo.{tablename} where email=@email--server1) AND RecordStatusID ='1' and FirstName=@fname and LastName=@lname END ELSE
IF EXISTS (SELECT top 1 email, FIRSTNAME, MIDDLEINITIAL, LASTNAME, TITLE, COMPANYNAME, ADDRESS1, ADDRESS2, CITY, STATE, ZIP, COUNTRY FROM {databases}.dbo.attendees--server1 WHERE email =@email and FirstName=@fname and LastName=@lname) BEGIN SELECT TOP 1 email, firstname, MIDDLEINITIAL AS MIDDLENAME, lastname, title, companyname, address1, address2, city, state, zip, country FROM {database}.dbo.attendees --server1 WHERE email in (SELECT DISTINCT email FROM server1.dbo.ebooksrequests--server1 where email=@email) and email=@email and FirstName=@fname and LastName=@lname SET NOCOUNT OFF
I've searched the forums and found posts stating that there is no connection governer in the 2005 edition, but I am getting connection limitation errors. I have Standard Edition with 25 CALs.
------ A problem occurred when attempting to contact the server (Server returned: Connection reset). Please ensure that the server parameters passed to the driver are correct and that the server is running. Also ensure that the maximum number of connections have not been exceeded for this server.
I have a problem with querying systemjobhistory data. Response time is slow and it is vary from time to time, sometime it takes few seconds and sometime it takes more than 2 minutes. I understand that there is quite a number of jobs in DB server and which might result in slow response time.
Is it possible to shorten the response time? like using index? My application is always look like hang when the query take very long time to run.
Hi,I am using MSSQL 2k, and I have a linked server set up to an Oracle RDBversion 7. It goes thru an OLE DB provider for ODBC drivers on a systemDSN, which is using an Oracle RDB ODBC driver version 3.0.2.The problem occurs when I send a query that returns zero rows - queryanalyzer just does not complete nor return. This problem is not seenwhen there are rows being returned.I ran a trace and this is the error message I get-:Non-interface error: OLE DB provider MSDASQL returned an incorrectvalue for DBPROP_CONCATNULLBEHAVIOR which should be eitherDBPROPVAL_CB_NULL or DBPROPVAL_CB_NON_NULLAnybody who experienced this before has a solution?Thanks,Lawrence
Does enabling/disabling Data Execution Prevention have a performanceimpact on SQL 2000 or SQL 2005?For SQL best performance - how should I configure for:Processor Scheduling:Programs or Background servicesMemory Usage:Programs or System Cache
I am using two almost idential laptops, one with XP and one with Vista, the only differences is that the XP laptop has 1G of RAM and running Office XP and the Vista has 2G RAM and is running Office 2007.
I have a MS Access database that has linked tables to a SQL Server 2000 database. The performance of the Access database on Vista is 5-10 times slower on the Vista machine. Just flipping through records or opening forms can take 5 - 15 seconds on the Vista machine while the XP machine takes 1 sec or less.
What gives? I looked at the CPU performance and the network performance while the Access database was busy flipping through records, the network traffic was < 2% and the CPU would spike to 40% on one of the CPUs (dual core) but would remain under 5% most of the time.
I also previously had Office XP installed on the Vista machine and it had the same performance issue so bought and install Office 2007 on the Vista machine and it did not solve the problem.
It seems that Vista is doing something that is slowing down Access with linked tables. Is this a issue between Vista and using an ODBC connection to SQL Server?
I have a procedure that calls a SVF to convert an xmldocument. The ultimate purpose is to update the xml in a column in a multi-million row table. The xml is stored as varchar(MAX), it was supposed to carry any type of text, initially at least.
My question is: why is the xml-parsing performed inside the function much slower when i pass the xmldocument as type xml than when it is passed as varchar(MAX) and the CAST to xml is within the function? Does processing the xml input parameter in SlowFunction involve expensive crossing of some context border?
The two versions of the SVF (they return the rowcount in this simplified example):
CREATE FUNCTION [dbo].[FastFunction] ( @inDetaljerText varchar(MAX) ) RETURNS int
[Code] ....
The two versions of the SP
CREATE PROCEDURE [dbo].[FastProcedure] AS BEGIN SET NOCOUNT ON; select dbo.FastFunction(al.Detaljer)
I can create a linked server to another MsSQL from MsSQL,but encounter error when create a linked server to MySQL: Error 7399:OLE DB provider 'MSDASQL' reported an error. Data source name not found and no default driver specified. ......
