Running Multiple Db Servers For One Db (import/exp
Feb 29, 2008
Hi,
I have zero experience running any databases that spread further than 1 machine, so I have a few theory questions here that hopefully someone can help with. Hopefully this is the right forum, I'm not sure if it classifies as 'clustering'.
Anyways, we are launching a web app that is going to start with just 1 webserver/db server. For speed reasons, after some growth we might have to have a load balanced setup with a webserver in europe and one in north america. Basically the webservers are going to be serving 100,000's of files and each time a file is served it needs to be recorded in the database.
I think that if I'm connecting my european webserver across the internet to my db server, thats killing the purpose of having a webserver in europe to make for faster responses.
I am thinking that this european web server/db serving is only going to be logging the files served. Is there a way to import them into north american database everynight ?
I'm not sure what the best approach would be for something like this, but any suggestions are greatly appreciated.
Thanks very much,

Hello,
We have an environment with 7 servers that are running replication with one another and I'm wondering if there are any tools or experiences that any of you might have that may assist in the auditing of these servers. The data should be in synch accross the boards for all tables, but sometimes problems can arise such as replication not being set up properly, stored procedure's being out of synch, or data gliches etc.
In dealing with these issues we have an in-house written program which analises each table on each server and takes a snapshot and does column by column compare. We also have another program that will synch the data up (basically a delete/insert statement on the publisher). This process can take up to 3 weeks for our quarterly update of every table. I'm wondering if anybody has used any tools such as in SSIS or a third party tool and has done or is doing something similar to what we are doing now. If so, are there any tips you wouldn't mind sharing on how our process might be sped up?
Thanks,
Phil

Hi,
I'm trying to create a database that takes specific information from a number of databases on different servers to make some reporting that we have much easier.
I'm pretty new to SQL so I'm not sure of the best way to proceed. I read an article that suggested I use the OPENROWSET command. The problem is, the version of SQL that came with one of the programmes we use is limited and will not allow you to turn on the allow "Ad Hoc distributed Queries" so the SLQ statement will not execute.
I'm confused why it won't let me to connect through ODBC as I've created a web page that selects data from this database with no problems!
Here is the SQL statement that I've written to make sure it is the correct one (on the msdn library page it said that this was the ODBC connection):
SELECT a.*
FROM OPENROWSET('MSDASQL','DRIVER=(SQL Server);SERVER=APPOLOACT7;UID=sa;PWD=***************',
'SELECT * FROM MDCTestAndDev.dbo.TBL_CONTACT') AS a
I've also created the ODBC connection using the tool on Administration Tools>Data Sources ODBC
Any help would be greatly appreciated (also any ways of selecting from one database and inserting it into another will be helpfull)
Thanks

I want to keep applications off of my database server so I have set up an application server (APPServer1). On APPServer1 I have a batch file that bcp’s data from DBServer1 into DBServer2 and is being passed the server name of DBServer2. On DBServer1 I have mapped a drive to the directory of APPServer1 and have created a task to run the batch job and pass the server name. So here’s my problem: when the scheduler runs the job, the bcp to DBServer2 fails, because it can not find DBServer2. When I execute the exact same command line in a DOS Box on DBServer1, the bcp works fine. I have verified that the server name is being passed correctly to the batch job in both methods.
Thanks in advance.

I had a website that ran with one server that had SQL 2000 as the DB. I have upgraded to two webservers with MS SQL 2000 on both machines and a load balancer in front of the two servers to handle sending requests to the server with the least load.
My problem is, I am not sure how to start to work my second server with the MS SQL. I need to make sure both DB's are exact duplicates of each other so if a user hits one server they are pulling up the same info as another user hits the other server.
I have a lot of queries running on the ASP pages I use, several pages use search forms for many various processes, and I have several pages that are for users to input information that is to be stored and sent out via email to all the other members.
Not by any means am I a SQL guru of any kind, I am lucky I know what it is
So, can anyone point me in the right direction as to what I should look for or into to work the best possible process to keep these DB's mirrored?
Now these servers are on their own private network using a second NIC card, I did this so the SQL can talk between the servers without using the public network bandwidth.
How do I keep these SQL DB's duplicated?
What are some great suggestions?
Have you done this before? if so, what has worked best for you? Is it hard to do for someone with limited DB experience? (I learn really quick if I know what I need to learn)
At this point I am confused as to what the best practice would be. Help?

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.

What is the best way to run SSIS scripts on different servers without changing connection information. Our test server is ppntt140 and our production server is ppntd110. If I create a script on server ppntt140 what can I do so I can move it to server ppntd110 without changing any connection information? Database names are the same, it is just the server that changes. What is the best way to handle this? Thanks in advance.

Hello
We have 1 machine running SQL Server 2005 x64 (64 bit). The other machine is backing this SQL Server up. It is a 32-bit machine, so it requires (?) a 32-bit version of SQL Server 2005.
Would this back-up machine work correctly on a database previously managed by a 64-bit machine and vice versa.
Thank you!

Hi.
While hardening a ms-sql2000 , I faced with a problem and I`m completely lost !
few days of reading and google searchs didn't gave me any hint...
Here's the scenario :
Ms-sql is connected to Oracle , through "MS OLE DB provider for Oracle" .
By default MS-SQL runs as SYSTEM , but even if we change it to a "local admin"
account , everything works fine .
The problem is that it's not wise to let sqlservice to run under privilaged accounts such
as system or a member of 'local administrators' . So I tried a normal local user on the
host running sql . I fixed every related problem appearing because of using a limited user
account and ms-sql works fine in all aspects but one !
While using normal-user account , sql-server fails to load linked-servers and this error
pops up in enterprise-manager :
"OLE/DB Provider 'MSDAORA' IDBInitialize::Initialize returned 0x80004005:
The provider did not give any information about the error."
I've tried much to find root of this error ( including any comments from related KB articles... ) but no luck . My guess is that , using OLE requires administrative privileges on host , and as I'm running SqlService with normal user, it fails to use OLE. So I should give requried permissions to the user running SqlService . But the problem is that I've no idea where/how I should do that. I've already tried some registry/file permissions but non of them helped me.
Some where I red that using ODBC instead of OLE may help , but that seems fail too !
*Note that I'm almost sure it`s a problem OUT of circle of ms-sql , meaning any modifications should apply OUT of ms-sql , because simply giving local administrative privileges to the user, fix the problem.
Any comments?
regards
Hamid.K

Hi All,I have recently published a website to our webserver and i get a sql error. We have a webserver that does not have sqlserver on it and and our database server which does. i have used the configuration utility to to setup my users and roles which created the ASPNETDB in my local App_Data folder. Is there a way to copy this database to our database server and change the references so the site refers to the new instance on the database server as apposed to the local instance when a user logs in?ThanksBryan

Question:
How to prevent a user/admin on one SQL 7 server, who knows the system admin password that is common to both servers, from accessing a second SQL 7 server via the SQL Server Group setup process.
Is there a way from shutting off remote access to a SQL server without limiting RPC?
All reading points towards 1) Remote Access Options, 2) Store User Independent, 3) Control Store as options to locking down a server. Would like to hear from someone that ran into this type of issue. Third party software available?
I've tried the following without any success: 1) I have deleted the second SQL server registration from the first SQL server group - but this is too easy to delete and recreate, 2) edit the SQL server registration for the remote server and force authentication - almost there if SQL prevented deletion of the registration without verifying the logon/password of the person who created it (again able to delete and recreate), 3) played around with the client utility to remove the TCP/IP pipe entry.
Anyone else pulling their hair out on this?
TIA!

I'm sort of new at MS SQL Server - I'm trying to gather system table information from multiple servers about backups on our site and insert the rows the query returns into a table on one central server where I'm running the stored procedure from. I have the server names stored into a table but when I attempt to connect to servers, I get an error which tells me that I need to create a linked server by using sp_addlinkedserver stored procedure. People that I work with tell me they want to do this without creating linked servers - Is there a way to accomplish? When I run the query, it only retrieves data from the local server I'm running the stored procedure on, but like I mentioned, when I attempt to connect to other servers, I get the error message that it couldn't find the server name in "syservers" and that I need to run sp_addlinkedserver. This also happens if I run the same query in OSQL from Windows command line.
Any help on this would certainly be appreciated.
Thanks in advance.

I can do itwith the import wizard but it takes to long. The files will be updatedmonthly. The first row in the files contains all the header informationwhich may change monthy. What I am looking to do is import all of thesecsv into tables. One csv file into for one table. Ideally I would liketo use the name of the csv file as the name of the table.

Hello All,
I am a newbe at MS SQL 2005, so if this has already been answered elsewhere, please just point me in the right direction.
I have successfully used the Import/Export wizard in "execute immediate" mode to import a table from Oracle 10g to MS SQL 2005. Works like a charm, but when I take the saved pacakge (saved as a *.dtsx server side file) - with no changes to the package and execute it from the either the "dos" prompt or from Windows explorer it fails at the login to Oracle step. Yet when I check the package's "Connection Managers" source connection, all the settings, user-ids and passwords look fine. The package does indeed execute, but I receive an ORA-01017:invalid username/password within the trace file of the package, but nothing has been changed from the Import/Export wizard which ran beatifully, thus verifying the appropriate acccess rights to Oracle.
Any advice would be greatly appreciated.

Hi,
We are planning to upgrage our SS 2000 databases(couple of hundreds) to SS 2005.
To minimise the potential work arounds, it is agreed to have complex databases, continue running on compatibility mode 80. What are the potential impact of having database on mode 80(apart from not being able to use new feature)on SS2005?
Fruther how we can we import SS 2000 DTSs to SS 2005 SSIS in an cluster environment?
Thanks,

We have a growing number of servers and databases on each server that all share the same (sub)set of sprocs and UDFs. DTS packages, which we use for data import, frequently need to be copied between the servers. What is the best way to maintain this? Ideally, I would like to be able to click a button and have a script creating or altering one or more sprocs automatically run aginst all DBs on all servers. Likewise, I'd like to be able to copy DTS packages to all servers.
We use SS2000 SP4 and plan to migrate to SS2005. We also use ASP.net 2.0 and VS 2005 SP1.

Hi, I was wondering what the licensing requirement would be for following scenario:
1 active sql server installation installed on a windows failover cluster.
1 passive mirror sql server (single server).
1 passive log-shipped sql server (single server).
In the microsoft white paper it says:
When doing failover support, a server is designated as the passive server. The purpose of the passive server is to absorb the data and information held in another server that fails. A passive server does not need a license, provided that the number of processors in the passive server is equal or less than those of the active server. The passive server can take the duties of the active server for 30 days. Afterward, it must be licensed accordingly.
So do I need to buy an enterprise license for each of the additional passive servers...in the above example meaning I would need 3 licenses in total?
Thanks,
Paul

Apologies if this question has been asked before. I am about to upgrade a multiuser application based on Access97 and VB6 to C# and possibly SQL Server Express.
My customer does not want to use a server based database solution ie a single instance of SQL Server, but prefers to have a common networked dataset which is accessed via user's own individual database engines. This is because of restrictions on the installation of server based apps.
Does this scenario completely rule out the use of SQL Server Express?
Thanks

Can anyone outline some best practices for sending the same message out to multiple servers? What is the easiest way to do this?
Currently, I have a message sent from Server A to Server B, which is fired by a table insert, update, delete trigger.
The goal is to keep this table synchronized on many remote servers. It sounds like a tedious exercise to deploy the SSB messages, queues, services, etc to 20+ more sites! I am hoping there is a shortcut of some kind.
Any advice is appreciated.
