Database Mirroring Using Certificate? (two Principles And One Mirror)
Dec 22, 2006Hi, all.
here is the situation.
we designated one server as a mirrored server. this server will host all mirrored databases from different principles in different server using certificate.
1) Server A (Principle) Server B(Mirrored)
2) Server C (Principle) Server B(Mirrored)
I was able to set up mirroring between A and B. But unable to set up mirroring between C and B.
My question is "Can I grant connect on endpoint to two different host logins?"
For example, on the server B
I created two different logins for Server A and C in order to assign different certificates to two principle servers.
For Server A.
create login server_A_login with password = 'djkkajnxks';
go
create user server_A_user for login server_A_login
go
create certificate server_A_cert
authorization Server_A_user
from file = 'c:certificateserver_a_cert.cer'
go
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO [server_a_login];
GO
For Server C.
create login server_C_login with password = 'djkkajnxks';
go
create user server_C_user for login server_c_login
go
create certificate server_c_cert
authorization Server_c_user
from file = 'c:certificateserver_c_cert.cer'
go
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO [server_c_login];
GO
when I set up like this and try to start mirroring, I am getting error from server c saying, "the network tcp:serverb.corp.com can not be reached or does not exist"
But mirroring between server a and b is OK. I set up them first, then between c and b.
any ideas?
thanks,

Jun 29, 2007Hi, We are trying to implement Service Broker between SQL Server Express and SQL Server on the Same machine and we are having problems with certificates.

Reporting Off Of A Database Mirror
Aug 24, 2006All,
I have created an asynchronous database mirror and a snapshot of the mirrored database similar to what is described in the following article:
http://msdn2.microsoft.com/en-US/library/ms175511.aspx
The article says that once you create the mirror that "At this point, new client connections can be programmatically directed to the latest snapshot."
My question is, how can you programmatically direct connections to the latest snapshot?
Does anyone have a suggestion, or know what the article is getting at? We will use SQL Server Reporting services to query off of the database snapshot.
Thank you,

Mirroring Mirror Database
Jun 13, 2007
I have two questions here.
Question 1:
If I am using Database Mirroring for my production database in SQL Serever 2005, can I do mirroring on the mirror database?
Principal Database -- Mirror -- Mirror A -- Mirror -- Mirror B
Can this be done?
Question 2:
Can I do 2 mirroring on a single principal database? If can, which mirror database it will goes when the failed over happen? can the other mirror switch to mirror the failed over database?
Principal Database -- Mirror -- Mirror A
-- Mirror -- Mirror B
Please advise. Thanks

View 4 Replies View RelatedMirror And Witness Connection In A Disconnected State Immediately After Adding Witness Server To Mirror Session.
Jan 31, 2008
After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
Thanks,

Service Broker Mirror Database
Feb 14, 2007Hi
I tried to setup service broker to fail over to a mirror database. After the target database failed over, the message I send stays in sys.transmission_queue with no error in transmission_status. I check the mirror server log and I see the following.
An exception occurred while enqueueing a message in the target queue. Error: 15581, State: 3. Please create a master key in the database or open the master key in the session before performing this operation.
The database has the master key because its a mirrored database? Did I have to do something extra here

Recovery :: Mirror Of A Database Part Of AlwaysOn AG
Sep 14, 2015We have an AG scenario where we are using WFC on a 2 node cluster. We are then using AG for mirroring the databases to both nodes and have a listener.
What I want to do next is to establish another copy of the database at a remote location. But I don't want to add the 3rd system to the WFC. I am not a big fan of WFC and I have seen it causes many more problems. The 3rd system will be in a remote location and the network not 100% reliable. I have seen in the past that it causes the entire cluster to hang and causing my production to crash which I don't want.
I there a way to add a 3rd node to the mirror configuration. I don't know if I can add a 3rd node to the AG unless it is part of the same cluster.
I know I can configure log shipping, I am fine with it but in the source, I have no control of which node the DB will be. I am not sure if a log shipping scenario can be configured using the listener instead of the physical host.

Mirroring :: Authentication Failing For Mirror Database
Aug 24, 2015When I try to setup mirror on a SQLserver dbase using windows Authenticated login I get error:-
Login failed for user 'SERVERBAdministrator'. (Microsoft SQL Server , Error: 4060).The login connect string however on selection of SERVERB from SERVERA has a greyed out option for using Windows Authenticated login which clearly shows Username: SERVERAAdministrator.It is odd that the error coming back is showing SERVERBAdministrator on the rejection. (somehow the machines got swapped over in the authentication) The strange thing is if you use the SQLserver studio on SERVERA to connect to SERVERB using the object browser and Windows authenticated login it all works fine without errors. clearly the Mirror software is using some other means/privs of login to establish the connection.
The two machines SERVERA and SERVERB are in the same Domain (DOM1) but they are not using a domain user account.They are using Administrator user on both independent machines. The SQLSERVER install specified both Windows and sqlserver logins. The mirror is to use Windows authenticated login.Is there some login priv we are missing The sqlserver security has allowed this type of login......
Database Mirror + Snapshot + Replication Questions
Aug 28, 2007All,
We have SQL 2005 db mirror configured with a witness server for high availability. Node 1 is the principal and Node 2 is the mirror. A nightly job creates a snapshot on Node 2. The snapshot is used for previous day reporting queries. We have now been asked to present another copy of the database for near-time reporting. I thought about possibly adding a peer-to-peer replication as part of my environment but was hoping to see what everyone else out there is doing.

Why SQL Server 2005 Database Mirror Can't Failover?
Jun 28, 2006
Hello All,
I've tried to replicated exactly what it says in the online documentation. At the end of the post are the SQL statements issued.

2. Enable encrypted outbound connections on the mirror server
3. Enable encrypted outbound connections on the witness server
4. Enable encrypted inbound connections on the primary server
5. Enable encrypted inbound connections on the mirror server
6. Enable encrypted inbound connections on the witness server
7. Set mirror''s partner to the primary
8. Set primary''s partner the mirror
9. Set principal€™s witness.

Disconection Of Database Users In Mirror Configuration
Mar 21, 2007On the machine DBSP01 we have the TEST database running. In the SQL environment we created the user Test. This user was set up to be the database owner of the TEST database. To make a connection to the Test database, the user Test was used and everything works perfect.
On the machine DBSP02 we also created a database called TEST and a user called Test, who was database owner of the TEST database. Again we where able to connect to the database by using the user Test.
Now we set up a so called mirror configuration. This means that we have one active database, called the principal database, and a standby database, called the mirror. The active database is used to communicate to the outside, while the standby database is copying every change from the active database. This way the principal database and the mirror database contain always the same data. When one of the databases is acting as a mirror database, this database cannot be reached from the outside.
After a while it can happen that the principal database fails for some reason. The database is not capable to run properly, so it stops. The mirror database will become the principal database and the outside can connect to the new principal database. Here we have a problem: the user Test is no longer the database owner of the TEST database. For some reason the user Test is disconnected as database owner of the TEST database when the database is acting as mirror. I can€™t find the reason for this problem and I can also not find a solution for this problem.
Problems On Database Mirroring (Loss Of Mirror And Witness)
Nov 29, 2006Hi guys , I would like to know what's the exactly results able to get in this following scenario.
Server A : Principal
Server M : Mirror
Server W : Witness
1) Firstly, disable server M, following by server W. So probably i will unable to connect to Server A eventhough it acts as a principal.
2) Next, if I enable either server M or server W , what will I able to get actually ? Is it the mirroring works like the article which written in Microsoft page ?(http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx#ETPAE)
At here, I get an error message and unable to continue the mirroring section. ( "Database EMS is enabled for Database Mirroring, but neither the partner nor witness server instances are available: the database cannot be opened." or "Database 'EMS' is being recovered. Waiting until recovery is finished." )
3) If I enable both server M and server W, the mirroring continue to work again.
Can I have any assistance on (2) issue? Thx for the assistance.

Hans
