I am running Microsoft SQL 2008 R2 database server I have a mirrored database that shows in the following state 'databasename (Principal, Disconnected/In Recovery)'. When I look at the mirror server is shows in the same state 'databasename (mirror, Disconnected/In Recovery)'. I am not able to do anything with either DB, I cannot break the mirror, I can't take it offline, I cannot delete it. This is a Dev Database so if need be I could destroy it and re-create. But I would like to figure out what the issue is and get it working again in case I was to have this problem in production.
Thanks for any Help!
We are using mirroring in Sql Server 2012 and we are using WMI alerts for some of events such as Connection lost,Manual failover,...
In alert definition we have set the followings:
Type: WMI event alert
NameSpace: \\.\root\Microsoft\SqlServer\ServerEvents\MSSQLSERVER
Query: select * from DATABASE_MIRRORING_STATE_CHANGE where State = 6
The alert is bing triggered correctly,but on email description instead of having meaningful explaination like 'Connection lost',We have the same query:
Query: select * from DATABASE_MIRRORING_STATE_CHANGE where State = 6
We have used the same implementation in our Sql Server 2008 servers and it is working fine.This mashine (Sql Server 2012) is a new mashine.
I would appreciate if someone help me on this.AlsoI checked and 'Include body of e-mail in notification message' was already set.
Thanks

Hi All,
There is a requirement to configure a user who should only have to have access on one database out of all and also need to alter only one sql agent job among all. Verified Server and database roles but haven't seen any option like in that way, is there any possibility please suggest on this.----Learners Curiosity Never Ends----
Hi
I am using SQL 2008 R2 and trying to create a script to setup database mirroring. The following steps fail with the error "The remote copy of database "XXX" has not been rolled forward to a point in time that is encompassed in the local copy of the database log." However when I run the backup, restore, and set partner script manually I can configure database mirroring, so I cannot see where this message is coming from. I've spent all morning trying to figure this out with no success. Could someone please shed some light on this issue?
Thank you
1. On principal server, run following
DECLARE @fileName VARCHAR(256)
DECLARE @filePath VARCHAR(256)
DECLARE @DBName VARCHAR(50)
DECLARE @MachineName VARCHAR(50)
SET @filePath = 'E:\SQLData\MSSQL10_50.MSSQL2008STD\MSSQL\Backup\'
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name IN ('XXX')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @DBName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @filePath + @DBName +'_' + CONVERT(VARCHAR(20),GETDATE(),112) + '.bak'
BACKUP DATABASE @DBName TO DISK = @fileName WITH COMPRESSION
BACKUP LOG @DBName TO DISK = @fileName WITH COMPRESSION
FETCH NEXT FROM db_cursor INTO @DBName
END
CLOSE db_cursor
DEALLOCATE db_cursor
GO
2. Copy backup file to mirror server
3.On mirror server, run following script to restore full database and transaction log
DECLARE @fileName VARCHAR(256)
DECLARE @filePath VARCHAR(256)
DECLARE @DBName VARCHAR(50)
DECLARE @MachineName VARCHAR(50)
SET @filePath = 'E:\SQLData\MSSQL10_50.MSSQL2008STD\MSSQL\Backup\'
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name IN ('XXX')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @DBName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @filePath + @DBName +'_' + CONVERT(VARCHAR(20),GETDATE(),112) + '.bak'
RESTORE DATABASE @DBName FROM DISK = @fileName WITH NORECOVERY, REPLACE
RESTORE LOG @DBName FROM DISK = @fileName WITH NORECOVERY
FETCH NEXT FROM db_cursor INTO @DBName
END
CLOSE db_cursor
DEALLOCATE db_cursor
GO
4. Set partner to principal server
ALTER DATABASE XXX SET PARTNER = 'TCP://principalserver:5022';
5. set partner to mirror server
ALTER DATABASE XXX SET PARTNER = 'TCP://mirrorserver:5023';
Msg 1412, Level 16, State 0, Line 1
The remote copy of database "XXX" has not been rolled forward to a point in time that is encompassed in the local copy of the database log.
We are currently running a production sql server 2005. I want to a quasi-real time (few hours difference) synched copy of a user database in our current 2005 environment in a sql server 2012 environment.
Initially, plan to make a backup of the user db in 2005 and restore in 2012. After that do a differential backup in 2005 and then restore it 2012 every few hours. Or possibly some sort of SSIS package finding differences in certain tables I'm interested in and then updating. I want to minimize the size of the updates.
In essence, I want to be able to use the upgraded tools in 2012 on our 2005 production data. In particular, SSRS.
Does anyone have any suggestions? Pitfalls? Details?
Thanks.

I'm working on trying to resolve some performance issues that have cropped up in very strong correlation with a failover test we ran recently. The test involved failing over to the new mirror partner, which is a VM. After we failed back to the original server, we started seeing some issues which were not there previously.
I have a set of symptoms, but it's not clear which ones are caused by or causing the problem. For instance, one small, high activity table started seeing deadlocking frequently, where previously there was none. A process which updates data once a day, has started reaching a timeout, where previously it had no issues.
CPU usage is up by about about 2x. Soft memory faults are up by a factor of 2-3x.
I haven't found any causes for all these things, or why failing over the server would cause this to appear. There doesn't appear to be memory pressure in SQL(cache hit ratios are in the 99% range, and buffer page life is long). It doesn't appear to
be mirror performance, sync is maintained well with 1ms or less of backlog.
Any ideas why I'm seeing these widespread changes in performance?
Thank you!
Good Afternoon,
I am receiving the 1418 error and I'm a bit stuck on how to address this issue.
I'm running SQL Server 2012 on both servers.
I have verified my ports via Telnet. I have addressed the NT Authority issue and changed all services to the domain.
I am using Restoring with NoRecovery.
Endpoints are set correctly.
Hi,
What changes in the front end code is needed if mirroring is implemented for the high availability?
reddy.s
Hi Everyone,
I have a plan to create High availability for my database use mirroring in my company. Mirrored database will be placed in DRC and i need to create capacity plan for this.
But i'm not able to find :
1. How to count amount of RAM needed
2. How to count IOPS needed
3. How to count bandwidth needed for the I\O on the principal and mirror servers
4. How to count network bandwidth needed
Is there any suggestion where do i find answer for my questions? Thank you very much.

hi everyone.. after endpoints is configured in the mirroring while executing the mirroring, I am getting the following error....if anyone knows,please share your knowledge
"
TITLE: Database Properties"
Hi All
Recently we have set up an mirroring setup, We have done this by using certificates . The servers are not in domain and we have configured the mirroring, Mirroring is happening woith put witness server and when we are trying to add wtiness server it is throwing
error as 1456 "The alter databse command couldnot be sent to remote server instance tcp://<witness-instance>:<port>.
The database mirroring configuration is not changed.verify that server is connected, and try again.(Microsoft SQL Server Error:1456)."
We have checked that all 1433 and 5022 ports are listening on all three servers and we can able to telnet the server also.
PRINCIPAL Server : SQL Version is Standard edition 2008 64 BIT
MIRROR Server :SQL Version is Standard edition 2008 64 BIT
WITNESS Server : SQL Version is EXPRESS EDITION 2008R2 with SP2 32 BIT.
Can any one help me in this case as it is very crucial for us to have this.
And moreover when we are trying to create any endpoint on WITNESS SERVER with below code :
CREATE ENDPOINT Endpoint_Mirroring<o:p></o:p>STATE = STARTED<o:p></o:p>AS TCP (<o:p></o:p>LISTENER_PORT=5022<o:p></o:p>, LISTENER_IP = ALL<o:p></o:p>)<o:p></o:p>FOR DATABASE_MIRRORING (<o:p></o:p>AUTHENTICATION = CERTIFICATE HOST_B_cert<o:p></o:p>, ENCRYPTION = REQUIRED ALGORITHM AES<o:p></o:p>, ROLE = ALL<o:p></o:p>);<o:p></o:p>GO<o:p></o:p>it is throwing error as "
Msg 7878, Level 16, State 4, Line 11"
When i replace the above code with ENCRYPTION = disabled and ROLE= witness able to create endpoint and giving error as 1456.
Please some one help in this scenario.
Thanks in advance.

Hello
I’m trying to establish automated restore to the mirror base every night, on remote shared hosting server, to be backup for my production database. On my server I have full privileges, allowing me to use backup and ftp access but on the other side I have shared hosting with no SSH or RDP?
How to solve this?why during the log shipping setup if the backup folder is present on the primary server (local path) it is not taking instead of it is asking for the network path to the backup folder?
