Database Mirroring | Can Witness Live On Mirroring Server?
May 3, 2008
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?
Mirroring :: Database Mirroring Changes In Application
Oct 12, 2015Using 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....

Create A Testing Database Out Of Existing DB
May 24, 2007Hello All,
I was wondering if anybody can help me with the following question:
I'm working on the application where the Database, it's table (2) and several stored procedures are involved. The database is SQL Server 2000. It's also very old and involves a lot of operations, stored proc and so on. I just need to re-write a piece of the app which is using existing stored proc. Most of them are DELETE, INSERT and so on. I don't want to work with real stage DB and need to make a copy of the Database to my Dev box. So I tried:
* Right click, All Tasks, Export Data into the newly created database on my dev box.
That doesn't work, every time I try doing it, it fails somewhere in the middle of the process. I'm thinking it happens because of complexity of the database. I tried several options there already. Still nothing. I need the whole databse to be copied because I'm not sure which stored proc the app is using so I need them all, and tables too. Is there another way of doing this?
Thank you,
Tatyana

SQL 2012 :: Database Mirroring And NT Authority Account For Database Engine?
Dec 2, 2014I have just finished configuring my first test mirrored environment (High safety mode). I setup the database engine service accounts on each of the servers with domainuser. I inherited a production mirrored environment set up by someone else. On the production servers the database engine service account is NT Authorityuser a local account. I am trying to practice installing Windows updates within a mirrored environment and I not sure how to proceed when the service account is NT Authority user account. should I change the service account to a domainuser?

View 6 Replies View RelatedDatabase Mirroring Monitor Not Working For One Database
Apr 2, 2008I set up a new mirror server. Everything is good except that the Database Mirroring Monitor is not working for one of the databases. In the monitor the principal data is showing up as blank
If I look at dbm_monitor_data on the principal most of the data columns (e.g. Send_queue_size) are null where as they have data for the other databases.
Both servers are SQL Server 9.0.2047 Enterprise Edition.
Any idea what might be going on here?
Thanks in advance.

I have read on the web that high protection mode not recommended, except in the event of replacing the existing witness server. But I can't find the reason why anywhere. Can anybody explain? Thanks.

Mar 12, 2008Hi All,
Couple of questions about database mirroing.
1. Once the mirroring is setup is it possible to switch between high-protection and high-performance modes? If it is will I have to stop the mirroring, switch the modes and then restart it again?
2. Let's say the principal server went down and I manually failed over to the mirror server. Mirror server runs as a new principal server for a couple of days and then I bring the original principal server back up. What needs to be done in order to bring transactions on the principal server up to date?
Thanks.

Database Mirroring
Jul 30, 2007we want to migrate our production server , without taking the database down.so what we did was , we mirrored the databases from production to one of our development servers and we took the prodcution server for uprgrade.
so today we are moving back (mirroring) all the databases from that development server to our new production server.
my question is , when i move
productionserver_old(principal server) - having the script for principal server
development server(mirror server---->principalserver)) - having the script for mirror server , which is now acting as principal server
new production server(mirror server) - having the script for mirror server. will become principal server , once i moved all the databases
now while mirroring between the developement server and the new production server, i have to run the scripts for the mirror server only.
so both the servers are havign the mirror script now...
is that a problem, or any other way i can handle this....

Oct 25, 2006Hi,
Is there a way to automatically mirror/backup a SQL Express database with a SQL Server 2005 licenced system?
They will be on seperate machines on the internet.
I have done manual backup and restores but would like to allow constant updates to allow both databases to be synchronized.
I read that the SQL Server 2005 version has a mirroring facility but I also read that this is not possible in the Express version.
What other (automated) options do I have?
Thanks Andrew

Cross Geo Database Mirroring
Feb 26, 2008I'm not personally a DBA or claim to be a database expert, instead I am a software architect who works closely with database architects and DBA's. I'm presently architecting a system where we will have a smart client used in both Europe and the United States from the same database instance.
The system is to be used for performance testing of devices and then the results will be available to management through the same smart client used by test engineers etc. The first release is operational in the United States today with Poland coming online shortly.
Today we are weighing our options between having cross-geo database mirroring or merely having the database server in the United States with application server level caching implemented in Poland and the United States.
The .net framework's Windows Communication Foundation is used with a netTcpBinding and the service layer is asynchronous with the reliableSession option enabled.
Does anyone have any feedback on whether you would go with cross-geo database mirroring or would you use local application servers with possibly some caching capabilities at that layer? Please also describe the benefits and any risks associated with each also...
Thanks in advance,
