Mirroring And Logins
Oct 5, 2006
I've created some SSIS packages to move logins from the Primary server to the Mirror server. But I'm having a small glitch. Lets say I have a database dbA that's mirrored. I then add a login of some sort, say userA. userA's default database is dbA. When I add that login to the mirrored server, how do I get the default database to be dbA? Currently I'm getting the following error from Alter Login:
ALTER LOGIN [userA] WITH DEFAULT_DATABASE=[dbA]
Msg 954, Level 14, State 1, Line 1
The database "dbA" cannot be opened. It is acting as a mirror database. I'm currently adding the logins with master as the default and then using Alter to attempt setting it. I can mask the error with a TRY block, but if I fail over it seems I'm going to have an issue. Any thoughts on this would be greatly appreciated.
Thanks,
Larry

Hello,
I've a DB that is mirrored.
I've actually only one user. I've replicated the user with the sp_help_revlogin Store Procedure to create the logins with the same SID on both SQL servers.
Now the application that is used with this DB will handle per user authentication.
Of course the application will use SQL login for the users connections.
Now, I can easily automate the sp_help_revlogin usage for the creation of new users, but I've another problem. The users can change their passwords through the application.
I'm wondering which process using for this:
Dropping the users on the Mirror server €“ running the sp_help_revlogin on the primary to re-extract the login information and applying the login creation against the mirror server
Checking the modify date of the login in the master DB and dropping this login on the mirror and re-creating it from the primary
Do you have an idea or an advice for this case?
Thank you
Eric

Hi all,
I am using SQL 2005 (Enterprise Edition, SP2) Mirroring with a Principal, Mirror and Witness set to High Safety mode and am a little confused!
As far as I understand it, during a failover, although the database content will automatically be available on the Mirror any user accounts will need to be either manually created or manually mapped to the new principal. Is this the case? If so, I can't really see the purpose of using Mirroring (in my scenario anyway).
For example - We principally use the database servers for our web applications which we connect to using ADO.NET. Each database and Web app has a different SQL user account to allow access etc. If we experience a failover this means the users will not be able to use the web app until we have manually recreated/mapped the SQL accounts for each and every database. Surely this is a massive oversight?! Or am I simply getting the wrong end of the stick.
Any help/guidance would be greatly appreciated!
Thanks,
Richard

Hi guys,
I want to create an automatic job on SQL 2005 to transfer logins between 2 servers, (Principle and Mirror). If I use the transfer logins task I get the error:
"The database "x" cannot be opened. It is acting as a mirror database."
I guess this is because it is trying to assign the default databases for the logins??
I've also looked at [sp_help_revlogin] procs but that requires manual intervention.
How does everyone else transfer logins in this situation?
Thanks in advance..

I am in the process of implementing database mirroring. I am trying to get an understanding about manageable ways of keeping sql user logins synced between instances.
I have looked at KB918992 which makes sense for the initial intallation, but what about keeping passwords synced in the long-term. I don't want to have to manually set a users password on the failover every time they change it.
How is everyone else accomplishing this using sql logins (not windows auth)? Pointers to articles and/or documentation would be great.
Thanks.

ok, first, I know... I forgot to run a backup of the master database, and I forgot to run a script to caputure logins. Not that that is out of the way... I need to recreate the logins under the Securities tab below the databases. All the company databases have the user names and passwords assigned to them, but they are not able to login, because they are not able to authenticate to the SQL server first.
Is there a script that someone has that will copy the company database security info for the users and recreate them in the SQL security tab?
I know that I can rebuild them manually, but I need to delete them first in the application software, then delete them from the databases, and then recreate them in the application software... and as simple as that sounds... it is a slow moving process.
Any assistance would be greatly appreciated.
Thanks,
John

Hello,
I would move a Database to another server. I try to use DTS but I have problems with this process because DB have big tables, I think. I try to use DETACH and ATTACH procedures but logins doesn't export. And more, in new server there are already logins from another DBs.
What's the best way to solve this problem?
Please, help
Thanks

I am a systems analyst and work with an app that runs against 2 SQL Server DBs. Though I have some familiarity with SQL Server and SQL, I am not a DBA.
The app executable is tied to a Windows service.
When we install the app, we run a process that builds 2 dbs to include:
Tables, indexes, stored procedures, views and user accounts.
SQL Server is set up for mixed mode authentication.
Normally, the dbs run off the local db user accounts which are tied to local logins with the same names.
We have a client that wants to remove our standard logins so that they can run on only a Windows login.
I know I should be able to tie the db users to a Windows login.
And I can do the same for the service.
But I am at a loss as to how to get this done.
How do you associate db users with a Windows login?
When I have tried sp_change_users_login I get an error that the Windows login does not exist. (Though I have added the Windows account to the DB.)
Hope this all makes sense.

Server A = primary SQL DBs (mirroring origination)
Server B = failover SQL DBs (mirroring destination)
For database mirroring a witness is required.
Can the witness live in another instance of SQL on server B?

Using SQL Server 2008, we would like propose mirroring between two servers of a critical database. Since we initiate, may require to clarify on its purpose and also required changes from application end.Any changes required from OS Level? (I believe both servers IP or Host name should be added in host entries. Mirroring ports should be allowed/open including Principal and mirror server IP Addresses): Windows Team.Any changes required from Application? (Instance name, authentication: user name and its password should be added in web config files): Application Team.Any changes required from Network Team?Also for mirroring both the principal and mirror servers should be with same version, does it only mean SQL Server 2008 versions are enough or does it also mean to say build numbers 10.00.4000 should also be same.URL....

I need to set up asyncronous data replication across two clustered instances of SQL 2012 across 2 Datacenters. Both the datacenters have a common domain however the vlans are different. There are only 3 small databases on the primary instance.
any issue in setting up mirroring in this case as vlans are different.
Operating system is Windows 2012.

I need to copy 80 logins within the same SQL Server (7.0 SP1) from 80 "old" logins that I'll delete later.
I clearly need to maintain all the security options for the new logins.
Is there a way to do this, adding the logins with the new name and granting all security options? Is there a script that will do this task or can somebody help me in doing that?
Thank you.

Hi,
I have two servers (server1, server2). I was trying to access the data from server1 to server2. I linked the servers and set up the option for data access.
when I run the following command from server1: sp_remoteoption 'server2', 'sa', 'sa', TRUSTED, TRUE
It gives me the following error. How to handle this.
Server: Msg 15185, Level 16, State 1, Line 0
There is no remote user 'sa' mapped to local user 'sa' from the remote server 'server2'.
I appreciate your help.
Thank you.

I have a server that was recently upgraded from SQL 6.5 to 7.0 that contains almost 700 logins using standard security. Is there a limit to the number of logins that SQL will host? The logins/users have all been added using a GUI within an application and does not support NT authentication. Does this cause any known problems in SQL 7? When I right click on the database and go to properties / permissions MMC gets hung up. Also one of the systems analysts is convinced that SQL is dropping permissions (I disagree to this). Any one have any thoughts or experience with large numbers of logins / users?

Reason is if someone adds themselves to this group in AD they could have access to our applications im trying to figure out

Hello,I'm currently developing an access application which uses sql server as abackend.What i'm uncertain about, is how i should setup security without creatingtoo many sql server logins. I'm convinced that i should limit access to sqlserver, otherwise people can get in with other means than my application(e.g. odbc, sem, etc.).I've setup sql server in mixed mode and created a login for my applicationto connect to a database.So, what is the best way to implement tight security, but still be able tolog the current user and hostname? If a separate table is needed to createdusers and passwords, please tell me how to use it, i've never done thatapproach.Thnx------------------------------------------------------This mailbox protected from junk email by MailFrontier Desktopfrom MailFrontier, Inc. http://info.mailfrontier.com

On a huge Sql-Server 7 installation, we have various client applicationsdistributed along the Lan, accessing one main database.Each application accesses the db using one out of around ten logins. Most ofthem, have only DBDataReader right on the db, as they are consultationconsolles only.In order to monitor db usage, the customer requires some kind of log of useraccess.My need, mainly, is to INSERT a record into a log table, recording Date,Time, Login, Host of each access.But, and this is the problem, the job has to be done by the server itself,not by each client, because of various reasons:1) we don't like to increase rights of logins2) we don't plan to change anything in our custom client application3) few of those client applications have been developed by foreignsuppliers, so we cannot change them.My question is: does it exist any kind of authentication LOG, which I canwork on?Or, is it possible to activate a kind of TRIGGER, reacting on loginauthentication?Thanks in advanceAlberto

I'm monitoring 2005 while running our application by looking at
sys.dm_os_performance_counters, general statistics, logins/sec.
I began testing a .NET 2 application, and logins/sec went from 63 to 11,433 in 30 minutes. Even though I have closed the application, it is still showing 11,449 - the only thing that's happened in the last hour is that I've run some queries from QA. is this login number cumulative, or is it an actual reflection of logins/sec? How on earth could that many logins be happening when no one else can even get to that server?

Hi, I'm relatively new to the admin side of websites and DBs. In the past, with hosted environments I've been used to just using SQL logins to connect to the DB from a web app, but for something I'm delevoping at the moment I have control over the DB and web server and was wondering if using a trusted connection would be better. After reading around it seems that Microsoft warns against using mixed mode authentication because of clear text passwords, the DB I'm working again currently isn't in mixed mode. So far I have set up the application to run in its own application pool under a limited user account that also has limited access to the DB. Though like this every new application that needs access to a different DB would require a different pool. What I'm asking essentially is what's the best way of going about things; set up a new pool and user for each app that requires it, using a trusted connection or turn on mixed mode authentication on on the DB. Or a mixture of the two?
