Microsoft OLE DB Provider For SQL Server Error '80004005' On Load Balancing
Jul 7, 2007
I have posted this also in one forum. Somebody might have idea here.
We have four Windows 2003 advance servers with SP 3 configured on NLB.
Each of them has one NIC.
Recently we started to get frequent time-out error messages from web applications on those servers when they try to establish the connection with the SQL 2005. If you run web pages application to connect to sql server 10 times, 9 times you will get good connection results and 1 time you will get time-out.
Microsoft OLE DB Provider for SQL Server error '80004005'
Timeout expired
/common/mypage.asp, line 20
Connection to sql server is established with the connection string. Any idea how to solve this problem? Is there a connectionproblem? from NLB to Web to SQL?
We have tried doing some suggestions (e.g. LMHOST, IP, domain account for WEb to SQL connection, the Query Wait in SQL advance property.), but seems this timeout expired still exist
Can anyone help me in connecting sql server and asp. Wheneever try to do the connection, I am getting following error. All the connection string which i am using are correct.
After disconnected from VPN (Cisco) , I am not able to connect to my SQL. Getting the error Microsoft OLE DB Provider for SQL Server error '80004005' Timed Out.
Restarting the SQL Server or Reset IIS, nothing works.
If I restart the machine, it works fine again. If I don't connect to VPN, I have no problem.
I am wondering that might be the problem. I enabled all the protocols.

Hi everybodyMy problem with sql server is the following one:I've got my backoffice manager application done with asp technologythat works on sql server installed on Win2000 and running on IIS5.what I've done is simply doing a backup of my db and moving the aspapplication on another server: Windows 2003 with IIS6 and sql serververs.8.Then I tried to set up everything as in the beginning on the previousmachine(Win2K), but I'm getting this error:Microsoft OLE DB Provider for SQL Server error '80004005'[DBNETLIB][ConnectionOpen (Connect()).]Server SQL inesistente o accessonegato.(translated would be "SQL Server doesn't exist or access denied")/sitowebsite/bom/login.asp, line 13....where in the line 13 is set the connection to the database:Conn.Open Application("DBsource")which should be driven by what is set inside the global.asa file:Application("DBsource")="Provider=SQLOLEDB;server=127.0.0.1;database=db_nam e;uid=db_uid;pwd=db_pwd;"Application("WS_DB_TYPE") = ( "SQLSERVER" )I tried to restore the database just not losing information and nothinghappens.I tried also to create a new user and modify the properties as itshould be from the previous settings in the db(db_owner,....etc), stillnothing.any clue is appriciated.many thanks in advance.
when i am running a Stored Procedures, system always returns me error message below and Stored Procedures stops. please help

Hi!Currently we only have one SQL Server database in our production system. I would like to add one more SQL server 2000 database. I would like to configure them so that both server share the load and Failover. I did some research and I found that I can do this by installing the OS (Windows 2000 Server Enterprise Edition) and SQL 2000 Enterprise Edition on both machines using the windows clustering. I want both servers to be active. They both have a copy of the production data. What I don't know is that, if it is possible to synchronize the data on both databases using SQL Server Replication utitlites. From what I know one SQL Server must be Publisher and one Subscriber. Can one sql server be both? Because I want both sql server to be identical. Can I set up replication between more than 2 servers? We just need to add one server for now but I would like it to be expandable. In the future we may need more.So Please provide me some ideas and answers about the following.1- Can two SQL Server cross replicate (both update each other in order to be identical)?2 -Does replication work beyond 2 servers.?3- If you were to set up a production database; what do you recommend considering the load balancing and Failover using Windows 2000 Server Enterprise Edition and SQL Sever 20000 Enterprise Edition?Thanks,Michael

Lately we have come across a problem where our application is undergoing some extreme load against the SQL 2000 server database we have setup, where the server is hitting 100% CPU utilization each time. Currently the box is a 2 processor box.
Here is the question I have. I have seen under most SQL Server clusters that an active/passive setup is implemented. Where the passive server just exists as a failover mechanism. What I am looking for is some information on how to setup active/active setup where each server receives processes to handle.
Has anyone created a setup like this? Are there any standard benchmarking tools that can be used to see how this configuration increases performance? Is this setup more favorable than going to a 4 processor server as oppossed to our current 2 processor server?
BTW: We have noticed that after a web application where the user sits idle for a while the SQL Server application loses the connection with the application user...Is this the SQL Timeout causing the connection to disconnect?
I want to create a table in MS-Access. So I have written the following query.
Code Snippet select * from Openquery(KKACC, 'select * Into Temp from Table select 1 as col1')
But I am getting the following error.
Code Snippet
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC" returned message "Syntax error in FROM clause.". Msg 7321, Level 16, State 2, Line 1 An error occurred while preparing the query "select * Into Temp from Table select 1 as col1" for execution against OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC".
How can I resolve this error. Does any one have any work arround for this..?
We are having a conversation at work and the subject of load balancing with SQL came up. Right now we are running SQL Server 2014 on four (4) machines. I am using a AlwaysOn with Availability Groups (AG). Now I know that we can scale out the reading in AG by allowing the secondary serves to receive reads.
Is there a way to be able to do this with writes? Can I have in essences 2 masters that some how reconcile with each other? We are expecting a huge amount of writes in the near future and we need a way for SQL to handle the amount of traffic we are expecting with out any issues.
I explored the possibility of Peer - to - Peer replication; however, it seems that it would be more work if we are constantly making updates to the database scheme.
How is load balancing working in SQL Server 2000. We want to have two different servers as a back end for our web based eCommerce application. Is this possible? While there be any modification requirement in the application?
What is the meaning of Loadbalancing and how can I use this term to my advantage. Q2. How would I know that I need to do load balancing and how can I set it up.
I have wrote load balancing in BOL and did not get any thing on it. can anyone refer me to where I can read more about it.
We have a Intranet Application which uses IIS / SQL Server 7.0, we are trying to support the application for 30,000 + users.
Since SQL Server can only support upto 32676 user connections (Theoretically), is it possible achieve this with clustering / dynamic load balancing. Does MSCS and SQL 7.0 support this. Any other ideas, 3rd party software etc?????
How much traffic/load can a database server running MS SQL server takebefore it can't handle it anymore? And when that time comes, what are therecourses? Am I able to load balance it between separate servers?
currently am having a active / passive cluster sql 2000 server, due to the amount of transactions am moving to new high end servers with sql 2005 cluster.
incase the new cluster also doesnt stands the load what approach i should use similar to load balancing.
Why SQL Server 2005 Dosn't Supoort Load Balancing? I think Load Balancing is a feature of great necessity. Would it be probably added to other features in Next versions? thank every one
HiOn our SQl Server (2000) we can have queries that take at least 10-20mins(require full table scan fo billion row table). When one of these queriesis running it substantailly slows down very quick queries (sub secondqueries take several seconds).I believe there is no way to set priorities but was wondering if thereare other configuration settings that could help. The server is dualprocessor so maybe setting maxdop to 1 will help. Memory size isdynmaically assigned up to 4Gb but as the DB size is > 1Tb I'm not sureif allowing this much memory is actually decreasing performance when thequick query trys to get through.Any suggestions.ThanksMike
When a web application becomes overloaded with traffic, one can offload itby load balancing and clustering the front end web servers. What happenswhen the back-end MSSQL database becomes overloaded? Does MYSQL offer loadbalancing and clustering?
Hi guys, can I know whether 2 servers (load balancing) able to set up the mirroring on another server? From what I know, mirroring only can set 1 IP address for principal. I just want to double confirm on it. Thanks for any assistance here.
We have a massive database that users run complex queries on. The queries are never the same so caching cannot be used too much effect. When many queries are run at one time by the various users the system slows down.
What we are trying to achieve is maybe have a primary SQL Server 2005 machine and multiple (4-5) SQL Server 2005 secondary machines. The primary machine would get the query and would decide based on loads as to which secondary machine would fulfill the query.
We are not worried about failover and clustering and all that fun stuff. Our primary concern is to achieve the quickest execution of the query. We were wondering if SQL Server 2005 has any feature that enables query load balancing of some kind.
Is it compatible to set up SQL DB mirroring on 2 different physical servers (High availbility + FULL transaction safety + Automatic failover with a third server as witness) and simultaneously set up network load balancing between these 2 servers (option with Windows Server 2003 Enterprise) ?
If yes, which type of licenses do I need and how many (for SQL server 2005 and Windows Server 2003) with such a configuration ? - 4 physical servers in total : A, B, C and D - load balancing between A and B (same application)
- load balancing between C and D (same application)
- A hosts principal DB X, B hosts mirror of DB X - C hosts principal DB Y, D hosts mirror of DB Y - D is witness for A and B - B is witness for C and D - A and B : only internal clients < 25 - C and D : both internal and external clients (internal clients <25, number of external clients is unknown (>25) )
Hoping this description will be helpful enough for you... (I am looking for a very high availability system)
Thank you in advance for your support. This licensing question is pretty much urgent (for a bid) : a quick answer would be very appreciated...
We are looking at expanding our web application (C# and Sql Server). The module we are going to be adding will be far more processor intense (plotting and modeling) than any of the current code.
I need to know what the best design for this add on would be.
Would it be better to a) Keep the new module as part of the core db (entire application on 1 database) and use loading balncing between 2 (or more) servers to handle the huge increase in demand? b) Create the new module as a seperate database that runs on a seperate server?
If B is the best option (I am thinking it is not) is there a way to write easy and efficient queries and views of the 2 databases as 1.
Thanks

i have a table with 10,000,000,000 records and i need Select and Insert many records from or into this table in less than one second. i can't buy a very expensive hardware(Server) for this SQL Server 2005 but i can buy many medium price hardwares(Servers) for this SQL Server 2005. how can i distribute or cluster this table between many hardwares(Servers)? note: i have few users (maximum 5 users) for my database but i have a very large table and Sql server 2005 server need to respond to this users in less than 1 second. i want to distribute this huge table in seperated hardwares. becuase i can't buy a very expensive hardware from my server but i can buy many medium price hardware for my server. note: i need this: when a user run a select query on this huge table his/her request distribute between many hardwares not one hardware.
I am trying to achieve load balancing through service broker.
I have a 3 server setup:
server1:
Source Database where the requests are sent. This has two routes created on this to server 2 and 3 with the service broker instance id specified. The service broker matches both these routes to the destination databases on Server 2 & 3 and send the requests in a round robin fashion by itself.
server2 & 3: These servers have the destination databases. The databases are exactly same with same messages, contracts, queues, services, and servicing programs. These don't send the responce back and the source is also not expecting for any response from the target databases.
When I tested this scenario it was behaving in a different manner. If there are 20 requests, in a normal case 10 requests should go to either of the destiantion servers, but I found that sometimes it was 11-9 or 12-8 only once did it do a 10-10.
Also I want to know is it best practice to rely on the inbuilt feature of the service broker in matching the routes and sending the messages rather than doing it ourselves. I which case one has to write the logic for sending the message to appropriate target server based on the status of the destination queue.
I also want to know which would be the best technique to use to bring the two destination databases in a concurrent state.
I wanna display the compname [in competencies tbl], firstname & surname [in users tbl], position level [in positions tbl] and userlevel [in compuser tbl] but i get the ff error msg
Microsoft OLE DB Provider for ODBC Drivers error '80040e14' [Microsoft][ODBC SQL Server Driver][SQL Server]The column prefix 'CompUser' does not match with a table name or alias name used in the query.
My code:

I was wondering if somebody could help me... the following error message appears when I run an asp page... I did a google search and nobody appears to have had a solution to the particular problem I have... it's completely baffling but I'm hoping it's a simple setting.
Firstly, I'm sure the coding the correct as the asp page runs on two different servers correctly. I recently got a new server and the script does not appear to work with the Date function in asp on this new server. I outputted the SQL to the browser and then ran it through the Query Analyser(QA) and guess what, it worked! But when I run the asp page the above error crops up... now when I run the SQL through QA and alter the date value in the format 'dd/mm/yyyy' the above error appears in QA.. if I've lost you at this point let me know...
The way ASP passes the Date value to my SQL DB appears to be confused and it's really confusing me as it works perfectly on two servers and not the new one... the new server runs newer versions of O/S and SQL so I'm not sure that is the case... I've changed the date settings on the server so they all three servers match each other... so I have no where else to turn... any help and pointers would be much appreciated!
