SQL Server Used With Web Farm
Jul 17, 2007
I am developing a web app that uses a SQL Server backend and will be served by a Web Farm at some point in the future. Can anyone give me some guidance at to what the common architectual considerations are when using SQL Server with a Web Farm? Initially, would it be allright to continue to have a single SQL Server on the network, with several webservers connecting to it instead of just one, or would this be a big performance nightmare? Eventually, since the goal of using the Web Farm would be to reduce individual server load, I would think having multiple SQL server instances would be preferred. Is this even done in the real world? I'm not a dba, so I'm not quite sure of the how multiple instances would be synchronized so that they held the same data and how applications on varying web servers would know to connect to one or another (by varying the connections string, perhaps). Can anyone give me any guidance? Thanks!

I have implemented SQL cache dependency to invalidate cache whenever the result of the stored procedure gets changed. The stored procedure is written obeying all the notification rules.
Our problem:
As long as we are working on Local machine, Development server or Pre production server its working fine means the cache gets invalidated whenever there is any change in the result set. But the same implementation doesn’t work in Production. Cache does not get invalidated.
Difference in Production environment and other environment:
Production uses cluster SQL server, others use standard SQL server. Production has load balancing means application is deployed on 6 servers which hits same clustered SQL server. In application’s global.asax file i have Start dependency so I see 6 different notifications started in SQL server which is right. But whenever there is a change in result set the cache doesn’t get invalidated in any of the application.
My question is
Do we have to follow any different kind of implementation of SQL cache dependency for web farm and cluster SQL server scenario?
On the same note I would like to add, on the same SQL server I have one more database and a different application is accessing this database. This application is also using SQL cache dependency and its working fine. The only thing this .Net application is NOT deployed on web farm. Its deployed on single application server.

Hi
I am trying to create a scale-out deployment of Reporting Services
2005 on a NLB cluster web farm by following the instructions in:
http://technet.microsoft.com/en-us/library/ms159114.aspx
However, when I install and configure Reporting Services on the second
node, and then go back to the first node to join the second node to
the scale-out deployment (as described in step 11 under 'To install
and configure the second report server instance"), I get the following
exception:
ReportServicesConfigUI.WMIProvider.WMIProviderException: An unexpected
error has occurred. Details:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) ---

I have spent hours searching for ideas, but so far no success. I have
also tried the following:
1. Enabling DTC access
2. Ensuring RPC service is running on both web and db servers
3. Installing WMI Windows Installer Provider
4. Granting admin rights on both db and web servers to the account
under which Reporting Services is running
Any help or suggestions would be greatly appreciated. It looks like
this should be a straight-forward task.
Thank you.

Our topology:
Internal corporate network domain utilizing Integrated Windows Authentication between local workstations and the web and database servers. (domain similiar to: http://reports.ourdomain.com)
Machine #1: Windows 2003 Server w/SQL Server 2005 (SP2 and hotfixes applied) running SSRS.
Machine #2: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Machine #3: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Device #1: Arrowpoint load balancer for Machines #2 & #3 (w/sticky sessions).
We recently added 2 web servers and configured them to load balance the web requests to a seperate SQL Server machine. (the load balancing is done thru an Arrowpoint device not Microsoft NLB)
The installation of reporting services (on Machine #2 & #3) went smoothly and the configuration was a breeze. But we could not access the "http://reports.ourdomain.com/Reports" directory for reporting services on the 2 web server machines. We received the "401.1 - Unauthorized" http error.
Since we were using a domain name to access the report server we made sure to update the <URL> tag in the config files.
File location 1:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportManagerRSWebApplication.config
<ReportServerUrl>http://reports.ourdomain.com/ReportServer</ReportServerUrl>
File location 2:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportServer
sreportserver.config
<UrlRoot>http://reports.ourdomain.com/reportserver</UrlRoot>
We still received the error, so then we added a couple of entries to the HOSTS file on each web server:
File location -->
C:WINDOWSsystem32driversetcHOSTS
In order for the load balancers to "see" themselves from the domain reference we had to update the HOSTS file
on each web server to have the domain name "reports.ourdomain.com" point to the IP Address of the specific web server.
(we also added the IP of Machine #1 just to be safe):
MACHINE #2's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.2 reports.ourdomain.com #IP of Machine2
MACHINE #3's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.3 reports.ourdomain.com #IP of Machine3
Then the web servers were able to authenticate the users using IWA and NTLM
and we could access the report servers normally. Even the the scheduled reports
were being load balanced and emailed from the web servers which we didn't
expect to happen. (pretty cool!)
I hope this helps someone else as it tooks us about 4 days to figure this out.

Server Software
SQL Server 2000 (all sps up to date)
SSRS 2000 (all sps up to date)
Scenario:
1 - SSRS + SQL2000 Database server
2 - Web servers
We have installed SSRS on 2 web servers that are acting as a web farm for a central Report Server.
After we installed SSRS on the 2 web servers the scheduled reports on the central Report Server stopped working.
We tried disabling the ReportServer service on the web servers and then the scheduled reports began to work again.
Why would the ReportServer service on the 2 web servers interfere with the central Report Server?
Can the web servers be used to load balance the scheduled reports?
Any advice would be appreciated.

I have to install several AG on a cluster for a whole SharePoint production farm, it's a nice to have (1 AG for Search database, 1 AG for Profil database, 1 AG for Content database, 1 for applicatif, etc...) We have 2 Front End load balanced, 1 application server and 3 SQL HADR: 2 nodes on synchrone (sql 2014 enterprise licence) and the 3rd asynchrone (standard licence).
The SharePoint farm is configured with the SQL Alias on the primary node, then if there is a failover on node 1, I must move the sql Alias to the second node manualy, unless I'd configured this Alias to point on the AG listener of the availability group in order to use the automatic failover. But as we have several AG, should I create one listener per each AG?
And which AG listener should I have to configure on the SQL Alias then ?

Dear,
I have designed a SiteMap provider for SQL Server. But I am worried about the notification service of SQL Server. My SiteMap requires service broker enabled in SQL Server. When I have web farm (multiple clustered server) does the Sql Server service broker notify all the web servers? Or, it notifies only the server request?
Have anubody implement such scenario? Looking forward for your reply.
Sincere Regards,Sultan

In our current project, we are attempting to use Broker for the middleware for a "queuing" solution that helps in throttling & load-balancing incoming messages. These messages could potentially be either long-running jobs or simply an incoming flood of messages received from our integration web services that are called upon via BizTalk.
For the posting of messages onto the "to do" queue, we are implementing the "fire & forget" pattern that has been discussed here previously and on Remus' blog. This aspect of the design seems to work fine for us. Currently we have this setup where activation is occuring on the target queue, but we don't want to hold open a thread there on the server while waiting for our synchronous calls to various web-services on the processing "farm" to complete.
The next evolution of our design is to try and move activation from off of the primary SQL cluster itself (i.e. activation is currently happening on the clustered SQL boxes) onto the individual processing nodes. For this model, we are looking at using SQL Express on each of the nodes as has been suggested here on the forums for other similar scenarios.
For resiliance to any node failures, we do not want to "route" the messages to the individual nodes hosting their own queues but rather have those nodes do a "read" from the primary queue and do the per-message processing and performing either a committed EndDialog of EndDialogWithError based on the success of processing each task/message.
To invoke the processing on each of the nodes, we need some form of mechanism to send a "wake up" and do the "reads" since no message is being sent to the node itself for any form of activation based on a queue that receives the actual "job". On the same hand, we are considering having a "wake up" queue on the nodes where a simple "wake up" message could be sent to all nodes/queues and then activation on those queues would then invoke the processing "loop" for each node.
My question is how to best establish this "wake up" call to each node. I think I've read about a queue that is internal to Broker itself that receives a message when new items are received in any queue. My initial thought is to put activation on that queue and have a procedure that sends the "wake up" to each of the nodes in our processing farm.
I am looking for any input where others have attempted to solve this type of problem with Broker.

Bradley A. Hehe

We are using RS2005 for a year now and never had any problems especially with mail subscriptions.
Since we transferred from single RS machine to web farm everything works ok except mail subscriptions. Subscription sometimes (?!?!?!?!) refuse to export report to a document of any kind. I repeat that this is a random thing which is more often with PDF and less with Web Archive or Excel. We are using shared schedules and on demand execution of AddEvent stored procedure by night batches to send mail to users. Also, original error from RS log says something that this kind of operation is not supported for server working in native mode. We don't have SharePoint so we never used it in any other way then native mode and it worked.
Any idea will be appreciated!
Thanks in advance.
Update 26.06.2007
It seems that problem is not loading dll used to export report to a file but loading email subscription extension (dll that needs to be loaded for execution of email subscription.)
Original error from RS Log:

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?

Hi,
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?
Thanks.

When I proposed start to use SQL Server 2005 for new VS 2005 web sites, one of my co-workers responded that
we will update the old SQL Server 2000 databases to SQL Server 2005 when we are ready to use 2005 SQL Server.
Questions:
1. Any expected problems to upgrade old 2000 databases to new 2005 SQL Server?
2. I have installed both 2005/Management Studio Express and 2000/Enterprise Manager in my PC. Any expected
problems when running both 2000 and 2005 SQL Server at the same database server?
3. What is the best configuration for running SQL Server 2005 when we have old 2000 databases? Upgade or not upgrade?
TIA,
Jeffrey

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran

if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.

Dear all,On Win2000 server with SP3, I am trying to access a SQL Server 7.0database, "TestDB", from VB6 via a SQL Server ODBC system DSN using ADO2.7. In SQL Server Enterprise Manager, there is a login named "Tester".In its property window, NO "Server Roles" was assigned but its"Database Access" was set to "TestDB". This login was also made as theuser of "TestDB" with "public", "db_datareader" and "db_datawriter"selected as its "Database role membership". All the tables I am tryingto access in "TestDB" were created under "Tester".My code is like:Set conn = New ADODB.Connectionconn.Open "DSN=TestDSN;UID=Tester;PWD=test"Set cmd = New ADODB.Commandcmd.ActiveConnection = conncmd.CommandText = SQLset rs = cmd.Execute()If I set the SQL to something like "SELECT * FROM tbl_test", I alwaysget an error of "-2147217865" saying "[Microsoft][ODBC SQL ServerDriver][SQL Server] Invalid object name tbl_test". If I set the SQL to"SELECT * FROM Tester.tbl_test", everything runs properly. Could anyoneplease kindly advise why the first SQL is not working? Or in otherwords, why must I prefix the table name with its owner while the DBconnection is already made under that owner name? Thanks in advance.Tracy

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.

Hi Guys,
I have had SQL Server Express and Sql Server Management Studio Express installed on my machine for some time and recently tried to install a trial of SQL Server 2005 as well. (Yes, I'm migrating from Visual Studio Express to Visual Studio Professional, just as in tended!)
Everything went fine except that nothing seemed to be installed. I searched in all the obvious places - both on the Start/Programs menu and on the hard-drive: nothing.
A check under Add/Remove Programs showed that Sql Server 2005 Express was installed, but called SQL Server 2005.
So after a number of retries in which the install program kept saying that there was nothing to install, I selected every option under Advanced in the intall process. This resulted in stuff being installed and I now have SQL Server 2005 running on my machine, but no SQL Server Manager icon.
My questions are:
Where can I find the SQL Server Manager executeable?
Has anyone installed SQL Server Express, SQL Server Mangement Studio Express, SQL Server 2005 and SQL Server Management Studio on a single machine successfully? If so, what order did you install them in? (I'm planning on uninstalling everything SXQL Server related and starting again.)
Thanks very much for your help.
Regards
Gary

Hi
I have created a linked server from SQL Server 2005 (SP 1) to SQL Service 2000 (SP 4) with a sql server login that is available on both servers but with different passwords and permissions.
I am getting the following error while accessing the linked server in management studio based on the scenario given below ;
------ Error Message Starts
OLE DB provider "SQLNCLI" for linked server "(SQL Server 2000 instance name)" 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 18456, Level 14, State 1, Line 0
Login failed for user 'abc'.
------ Error Message Ends
Consider login name is abc.
Now this login abc has sysadmin rights on sql server 2005.
The same login abc has only db_datareader rights on sql server 2000 on just one database and is not associated with any fixed server role.
I have configured the linked server using the following options;
1. I have tried impersonating login from SQL Server 2005 to SQL Server 2000 .
2. I have also tried specifying remote login / password option.
Anyone having any idea, would be of great help.

Hello,
I have an intranet environment consists of two servers:
- An application server windows 2003 server with 64-bit server Sharepoint 2007 SP1 (Standard version for search)
- A database server windows 2003 server with 64-bit SQL Server 2005 SP2 64-bit (Standard - 9.0.3054)
It happens regularly that the database server crash (frozen black screen) while the application server indexes (crawl) the content of the intranet site based on sharepoint. There is no alert / error in the observer of events, nor in the sql logs.
The crash is uncertain: dice once all goes well, soon after that crash. When i set the parameter search service (service management research), I can define a regulatory impact of the robot to change the number of documents at the same time : "Request 2 documents at the same time, the crash is more rare, "ask 64 documents at a time, the crash is more common.
My Intranet under sharepoint is composed of a collection site with a dozen sub-sites. There are 3 large library of PDF document. All done in the 4 go in terms of volume.
My problem for about 3-4 months. (Maybe more. Before, indexing was not yet in place).
Someone could help me? Thank you
