SQL Security - Multiple SQL Servers
Feb 6, 2001
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!

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

How can I accomplish this? also if any one has already created a script similar to the one I am trying to create, could I please take a look at it to get some ideas?

Hello,
I am working on an ASP.NET apllication which will work with sensitve data that needs stored as encrypted. The ASP.NET application and SQL Server 2005 will be hosted outside of our company.
My questions are:
When I create a database master key, a certificate and a symetric key to encrypt and decrypt my data, will I be able to use these (master key, cert and symetric key) in other databases (say my local development SQL Server 2005 instance)?
Is a managed hosting a better solution to have total control over the the keys in the database?
Is there a white paper or guidance document for security in hosted databases?Thanks

Dear guys
I want to publish my web site and sql server on a hosted server. But i'm worried about people behind the server. all of my codes including web and stored procedures of sql server are open. as far as I know, there is no effective way to protect web pages source. how about sql server? I mean compiling stored procedures.
and another important thing is data. I think certain people have potential to see or change all of my records, or for example give email address of my customers to a third party or ... .
Is there any way?

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

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.

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 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,

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.

I'm using EncryptByKey to encrypt data in my SS2005 database. Since our server is really slow to access from home to work on, I used the Database Publishing Wizard and installed the db to work on at home. Then I created the certificate and symmetric key in my home db.
When I pull info using the DecryptByKey on our database at work on Windows 2003 Server, no problem, the data is decrypted. However, the same data does not decrypt at home on my Windows XP computer. I'm using TripleDes on both machines for the symmetric key (AES won't work on XP).
--To create my cert and key:
USE My_DB;
CREATE CERTIFICATE MyCert
ENCRYPTION BY PASSWORD = 'some password'
WITH SUBJECT = My Data',
START_DATE = '01/01/2007',
EXPIRY_DATE = '01/01/2099';
GO
CREATE SYMMETRIC KEY MyKey WITH ALGORITHM = TRIPLE_DES
ENCRYPTION BY CERTIFICATE MyCert;
GO
To encrypt:
OPEN SYMMETRIC KEY MyKey
DECRYPTION BY CERTIFICATE MyCert
WITH PASSWORD = 'same password as above';
Insert my record, use scope_identity to return primary key into @CustomerID.
INSERT INTO [Customers] (EncryptByKey(Key_GUID('MyKey'), @DataToEncrypt, 1, CONVERT( varbinary, @CustomerID)))
CLOSE SYMMETRIC KEY MyKey
To decrypt:
SELECT CONVERT(varchar(3925), DecryptByKey(EncryptedField, 1, CONVERT( varbinary, @CustomerID))) as PlainTextData
FROM Customers
WHERE (CustomerID= @CustomerID)
Everything works fine when I run the decrypt query on the database on our work server. But I'm not getting decrypted data at home. Is the symmetric key or certificate machine specific? If so, that will cause a huge problem when we deploy to a production server.
Thanks in advance for your help!

I have multiple SQL 2000 servers that hold data which I retrieve using a single SQL stored procedure. Unfortunately, I don't know how to retrieve this data asychronously (in parallel).
For example, I retrieve data from two linked servers using the following:
select * into #temp from openquery(SomeLinkedServer,'exec BigQueryHere')
select * into #temp2 from openquery(OtherLinkedServer,'exec BigQueryThere')
.
.
lots of manipulation of the temporary tables to get what I want, etc.
.
.
The problem I have with this is that there is no reason why the first query should have to finish before the second query begins (serially) because these are on separate servers. Is there a way to execute these so that they run at the same time?

Scenerio : To keep a very large system running optimally in a VM cluster, Take PR01 and make PR02, PR03, PR04. Distribute the 45 databases and 9T+ of disk across multiple VM guest.
Each PR## is a SQL Server 2012 Enterprise guest on a VM 5.1 cluster.
So instead of PR01 needed 16 core and 128g of memory, each one will have 4 core and 32g of memory. Making VM HA more manageable. (yes, DRS rules will apply). Also provides more HBA paths and distributes i/o over more physical disk on the SAN.
Instead of a connection string having to know PR01.dbo.UserDB01, PR02.dbo.UserDB03, ect the connection would be PRDB.dbo.UserDB01. That way if needed 1) UserDB can be moved to any of the PR## 2) new PR05, PR06 can be added as needed. The end user and processes are not allowed to touch system databases, no PR## will have a user DB called the same name.
There are seperate VM guests on other VM clusters and Citrix servers that need access to PRDB. As things expand and move around, none of the connection strings need to be changed.
I am looking into RadWare and modifing level 7 information, but that is iffy and $$$$$$.

Curious what the industry standard is combining multiple instances on single server ?
Right now i have separate servers for OLTP, SSAS, and SSIS, and for OTP have Development, Test, and production environments. Im considering combining the SSIS and SSAS services into additional instances on each environment servers.
Now (Production)
OLTP
SSAS
SSIS
After
1 Server with 3 separate instances for SSAS, SSIS, OLTP. Then replicate this model through the environments to utilize development and testing.

Hi everyone,I have 5 servers, all with identical databases just different data. Ihave a rather lengthy SQL statement (in a View) to hit one database andpull-in certain data, but I'd like to somehow run this same SQLstatement within the view but hit all 5 servers so we don't have 5different versions of this data to mess with.I'm not opposed to creating an update query in a stored procedure tohit all 5 databases and update a table or even do this within a DTS,but I'd prefer to keep it as simple as possible and as dynamic so theusers can simply run the view and get live data anytime based on all 5tables.Is this possible ???Thanks,rlangly
