SQL 2012 :: Restoring Mirrored Database To Different Server Occasionally Fail?
Oct 19, 2015
Every once in a while a scheduled restore of a production database backup to a development server will fail with the following error.
RESTORE cannot operate on database 'XXX' because it is configured for database mirroring or has joined an availability group
While it is true the production database is involved in database mirroring, the development server does not have database mirroring enabled. This error tells me something within the backup is telling the development server the database is configured for database mirroring.
However the perplexing part for me is that we only receive this error maybe 5% of the time, if that, and only on a couple of our databases. We have numerous other restores of mirrored production databases to development servers that have never produced this error. So my question is what is causing this error to occur, and why is it not happening all of the time? We get around this error by deleting the DEV database and re-running the restore job.

The database in Mirrored server is always in the state of restoring only.
the database in mirrored server is restored with norecovery
then we started mirroring.
the status of mirroring is successfull and is synchronized.
but the Mirrored server is always in the state of restoting
not allowing use to open the database.
could any one know why this problem is comming and give some solution for this problem so that the mirrored database can be accessible opened and queryed to really verfiy that the changes made in principal database is mirrored to Mirrored database.

I'm trying setup a proof of concept for a client but I€™m having issues with mirroring and replication.
With the help of http://technet.microsoft.com/en-us/library/ms151799.aspx I€™ve done the following..
The setup is as follows, I have several instances of SQL Server
A+B are mirrored with each other, with A being the principle and B the mirror
C is the distributor
E is subscribes to A, with parameters for PublicationFailoverPartner set to B
The mirroring between A+B works fine, I can manually fail each and the databases keep in step.
Without testing the mirroring failover, the replication between A+C+E also works.
However when I test the mirror to failover between A+B no transactions are replicated though to E. The publication moves from A to B in the Server Management Studio.
The logs state that the log reader agent can not gain access to A, however nothing is recorded regarding any attempts to contact B. In the replication monitor the error message
"The concurrent snapshot for publication ABCXYZ is not available because it has not been fully generated of the Log Reader Agent is not running to activate it. If generation of the concurrent snapshot was interrupted, the Spapshot Agent for the publica..." (cut off).
"the process could not execute 'sp_replcmds' on 'A'
I have checked that the SQL Server Agents are running on all agents,
I have checked that that server B is set at the PublisherFailoverPartner on server C agent configuration, I'm now at a lost as to what is wrong,
Any help or suggestions are greatly appreciated.

I need to increase the file size for a mirrored database. I am new to using mirroring for replication. Will increasing the file size break the mirror?

I have clustered SQL server machines(SSserver1 and SSserver2). I need to restore a database from another standalone server to this clustered environment. In this case do I need to restore the DB on both the nodes that are part of the clustering(SSserver1 and SSserver2) or Just can I do it on one of them?

I have a database with deployed CLR assembly on SQL 2008. I recently took a backup for the database and restored it on SQL 2012 server. Everything worked fine except very strange working of CLR assemblies functions.The result of the function is very odd. It manipulates the numeric string and return the result. It is returning very strange result on SQL 2012 as compared to SQL 2008.Example SQL 2008 ManipulateString('1234') returns 2345 On SQL 2012 the same call returns 1155.I am also trying to deploy the same assembly to SQL 2012 server database. I have successfully register the assembly, but the database do not list the exposed methods.

We have a Prinicipal, a Mirror and a Witness server. We have automatic failover configured between the Prinicipal and Mirrored server. When we stop MMSQL service on Prinicipal, not all the databases failover to the Mirrored instance.
Any suggestions would be welcomed as we have a tight deadline to get this in Production.

I am trying to restore a database called BCC_DB (I'm actually just needing one table opened to find some data in one column) so I created a blank database called BCCrestore.
I have a .bak file called BCC_DB_backup_201505020017.bak.
I placed it in my local drive C:BCC_DB_backup_201505020017.bak and tried the SQL:
RESTORE DATABASE BCCrestore FROM DISK = 'C:BCC_DB_backup_201505020017.bak'
GO
I get an error:
Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'C:BCC_DB_backup_201505020017.bak'. Operating system error 2(The system cannot find the file specified.).
Msg 3013, Level 16, State 1, Line 1

I need some clarification about adding file in to mirrored dataabse in primary server without downtime and breaking the mirror server.
In our environment we are using monutdisks in both the servers. in primary for ex we have F drive for data files under mount disk 3 in mirror server also we have same drive but in mount drive2.
As per my knowledge if it is same drives we can add the ndf files in the primary that will reflect on mirror. but in current situation i am confusing about mount points with different names.

Hi
I'm using SQL Server 2000 with Small Business System 2003. I have a smallish database and an Access 2003 Front End, with ODBC links. The system has been running fine for about 2 months with 16 users. This weekend, I will be adding a further 30 users to the system.
I've been doing some work on a new copy of the front end over the past day or two, and found that occassionaly, the system runs really slowly, taking a couple of minutes to open my front screen which normally takes a few seconds.
The only solution I have found is to stop and start SQL Server Manager on the server, and then everything is fine. However this is clearly not an acceptable solution, because I'm doing it about twice a day.
can anybody suggest why this might be, or how I might fix the problem?
I have a maintenance plan in place, which runs overnight,
Thanks for any help,
Colin

We are trying to restore from a backup (.bak) of a sql 2005 database with full text catologs to sql 2012.
We are getting errors saying that the backup file context are different from what we are trying to restore to, even if we try to create a new database from the backup.The new database is just a test database. The source is a production database with full cataologs.
The normal restore from a bak file does not seem to work.
We dont need the full text catalogs in the new database, but cannot change settings in the source production database.
Is there a way to take a backup of the sql 2005 database without the full text cataologs being included ? , without changing setting in the source database beforehand ?

I have a weird intermittent issue with an enterprise version of SS2014. When clicking or right clicking around SSMS will lock up and display the 'SSMS is busy - waiting for an internal operation to complete'. It is only specific to the server as when I connect using my local SSMS this doesn't happen. This was happening both pre and post SP1 install.

I'm having a problem with SQL2005 Database mirroring.
I have an ASP application that loops for a certain amount of interations and in each iteration I create a SQL Connection object and use the failover partner in the connection string. The object then writes a simple record and then the connection is closed and the process starts again.
About half way through my loop I force a failover to the server mentioned as the failover partner in the connection string. At this point my application encounters a SQL Exception error and the application fails.
I read in this article, http://msdn2.microsoft.com/en-us/library/ms366199.aspx, that this is expected and that you shoud request a new connection using the same connection string but this isn't working for me and unfortunately no examples are given anywhere.
I would appreciate any help. Thanks
Luis Bonilla
Here is a sample of my code:
Dim k As Integer = 1
Dim constring As String = "Server=SVR01.XXX.XXX.comInstanceName;Failover Partner=SVR02.XXX.XXX.comInstanceName;" _
& "Database=test;" _
& "Integrated Security=SSPI;"
Do Until k = 60
Using con As New SqlConnection(constring)
Dim cmd As New SqlCommand()
Try
con.Open() '<--------This is where the exception occurs
Catch ex As SqlException
Dim en As String = ex.ErrorCode
Dim em As String = ex.Message
Dim emm As String = ex.Number
Dim enn As Integer = ex.State
End Try
lblprimary.Text = "Current Primary Database = " & con.DataSource
cmd.Connection = con
cmd.CommandText = "INSERT INTO SystemsTest (FirstName, LastName)VALUES ('SQLWriter" & CStr(k) & "','" & con.DataSource & "')"
Try
cmd.ExecuteNonQuery()
Catch
lblresult.Text = "Results = Error with record number " & CStr(k)
End Try
con.Close()
cont:
End Using
Sleep(1000) 'For testing

Simple question, I hope. I need to add a column to a table of a database that is mirrored. How do I have to do that? Do I need to stop mirroring? Is it sufficient to simply pause mirroring? If I make the change on the principal db, what do I need to do the make the same change on the mirror?
Thanks,

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

I want to restore a database (from an encrypted .bak file) - but *not* over the live original if you take my meaning. Encryption is the standard AES-256 that comes with Sql Server 2014 btw. I don't want the original touched/altered in any way. I would like to capture a success message if possible.I can extract the physical device name of the database in question using the following code:
SELECT physical_device_name, *
FROM msdb.dbo.backupmediafamily
WHERE media_set_id =(SELECT TOP 1 media_set_id
FROM msdb.dbo.backupset
WHERE database_name='MyDatabase'
AND type='D'
ORDER BY backup_start_date DESC)
I would like if the newly restored database was rename to something different than 'MyDatabase' (as shown above) and has different logs than the original. If possible, and capture a success message when restored.

I did a full backup of a db from one server(Express2005) and trying to restore it to a different instance of SQL2005 on the same development machine. (Also had some fulltext columns if that means anything)
Many failures but finally got it to report all was successful except the icon in Object Explorer shows (Restoring...) with no indication of any real activity going on. It's a tiny database with hardly any data in it.
Just not sure what the heck is going on there. It also won't let me into the database until this the (Restoring...) goes away.
Any advice on how to get this thing finished out?

Heya all,
Sorry if this has been posted elsewhere, etc., please point me in the right direction if it has 'cos I couldn't find it!
Right, we have a mirrored database with full safety and a witness for automatic fail over, all works fine, very impressed with it. Now I need to backup the database involved and this is where I could do with some help and answers and/or tips.
As the mirror database is off-line/recovering it seems you can't back that one up, but I'd like to have something that tries to back it up for if/when it fails over and becomes the primary. The solution I've used for now is to write a small .Net application that uses the client side fail over connection string (Data Source=Server1;Failover Partner=Server2) so that it connects to whatever system is currently the primary, and then issues the relevant 'BACKUP xxx' statements to backup the database.
This applications is launched from a windows scheduled task job on the hour (or near to it), every hour. At 06:00 it does a full backup, at 12:00, 18:00 and 00:00 it does a differential backup, and all other times it does a transaction log backup.
This all seems to work fine so far, and generates all the relevant backup files to a share on another server.
So, my main question is; does this look like a good plan? Am I missing some really simple wizard or button that would backup the relevant database from whatever server is up?
Secondly, are the backups from each server interchangeable as they're in a mirrored configuration? That is, for example, the backup application (on the hour) connects to Server1 does a full back up, followed later by a log backup. Server1 then dies, so the next time the backup application runs it connects to Server2 and because of the current time does a log backup from Server2. If we had to restore from backups, could we use the full backup and log from Server1, followed by the log from Server2? Otherwise I'll guess I'll need to modify the logic for the backup application to detect it's failed over, and maybe do a full backup on Server2, or something like that.
Anyway, thanks for any help/advice/tips,
Gareth/OhGod

Hi all,
I am struggling with configuring SSB network routes to a mirror database. What I want to accomplish is to configure a SSB application to work in a database mirroring setup but I am not looking for a load balancing solution.
According to SQL Server 2005 Books Online (http://msdn2.microsoft.com/en-us/library/ms166090.aspx) the typical routing configuration for a service hosted by a mirrored database is set by specifying the 'mirror_address' field but leaving the 'broker_instance' field empty (i.e. NULL) in the sys.routes table (see Example 3 in link above). I haven't seen how this is possible because if you specify the MIRROR_ADDRESS parameter in the CREATE/ALTER ROUTE command then you must also specify the BROKER_INSTANCE parameter.
I haven't found a way to set the mirror_address field to a valid value and the broker_instance field as NULL, is this possible? If not I must set the broker_instance as the guid of my broker instance but my understanding is that it should primarily be used for load balancing configuration. My preference would be to not set the BROKER_INSTANCE parameter, is this possible?
Best regards,
Oli

I have a database I need to copy from a Prod server to a Dev server. There is not enough space on the Dev server. In looking at the size of the files on the Prod server, the Initial Size property for the transaction log on the Prod server is set to 100,000 MB though the log is using nowhere near that.
This is a mirrored database so the recovery model is "full". I know that to change the initial log size, I have to put the database in 'simple" recovery model. Is this possible? Can I just:
1. Pause the mirror
2. Switch recovery model to simple
3. Change the initial size property to something smaller.
4. Shrink the transaction log
5. Change the recovery model back to full and resume the mirror?
I honestly don't know if the transaction log is needed on the Dev server. Meaning I may just be able to restore the transaction log to a different location on the server and delete it so that new one is created.

I have set up mirroring in high availability mode (principal, mirror, and witness).
After setting up mirroring, I needed to adjust the size of a column in one of my tables. I did so with the following command
ALTER TABLE OrderOptimizer.dbo.rCodes ALTER COLUMN CodeDescription VARCHAR(8000).
The column was initially VARCHAR(128)
When I look at the table structure it shows that the column is now VARCHAR(8000), however I can only enter 128 characters into the field.
I forced a failover to look at the table on the mirrored version. It too showed that the column was VARCHAR(8000).
If I open the table I can enter more than 128 characters into the field, however when I refresh, it is truncated to 128 characters,
Any help would be appreciated

I've been running the Ola Hallengren maintenance script for the last five months without missing a beat. Today I find an error stating the UserDatabase Integrity check job failed last night. This is running on SQL Server 2014 BI edition w/64 Gigs.
I ran a DBCC CHECKDB on each database manually and all worked until I tried it on the biggest one that is about 18 gbs. It just keeps running and I eventually stopped it so I'm guessing it is memory, but doesn't make sense considering it has 64 gbs. I have it set to 64/4 max / min. Again, this was never an issue until last night.I've been looking up all morning, but not seeing much on this error "The operating system returned error 1453"?

I have two servers (same config) I am trying to restore a database that I backed up on one server to the other. The method I used was as follows: I backed up the database to disk.
Copied to the Disk of the second server.
When I try to restore I get the following message.
"The backup set holds a backup of a database other than the existing "database name" database.

Hi!
I attempted to backup a database on server x and restore it on a database on server y. The details are as follows.
Server X
Database name : dbx
Size :263.88MB (Unrestricted filegrowth option set)
Logical files : dbx_data, dbx_log
Physical files : e:mssql7datadbx_data.mdf, f:databaselogsdbx_log.ldf
Server Y
Database name : dby
Size :1MB (Unrestricted filegrowth option set)
Logical files : dby_data, dby_log
Physical files : d:mssql7datadby_data.mdf, d:mssql7datadby_log.ldf
I created a full database backup of dbx on server x at the location, f:ackupsdbx_083099_10.30AM. The size of the file is 272MB. I zipped the file. Copied the file, dbx_083099_10.30AM.xip over to d:ackups of server y. I unzipped the file at server y to the location, d:ackupsdbx_083099_10.30AMdbx_083099_10.30AM.
I now tried to restore this backup on server y using the statement,
restore database dby from disk = 'd:ackupsdbx_083099_10.30AMdbx_083099_10.30AM
with replace,
move 'dbx_data' to 'd:mssql7datadby_data.mdf',
move 'dbx_log' to 'd:mssql7datadby_log.ldf'
I get the following errors :
Server: Msg 3257, Level 16, State 1, Line 1
There is insufficient free space on disk volume 'd:' to create the database. The database requires 3219128320 additional free bytes, while only 2047102976 bytes are available.
Server: Msg 3013, Level 16, State 1, Line 1
Backup or restore operation terminating abnormally.
Error log shows,
