The Mirrored Server Is Always In The State Of Restoring Only
Jun 6, 2006
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.

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.

Hi guys, right now I am having insufficient hard disc space at the secondary server (Mirror side) due to the large db that I have. Therefore, I get a new HDD on the server (Assuming located at drive G) and would like to shift the current mirroring db to that new drive. Is it possible for me to do that ? Hope able to get any suggestion from here ASAP. Thanks.
Best Regards,
Hans

I noticed that after a SQL AlwaysOn failover, one of the DB in the secondary replica is stuck in Restoring state. The primary replica shows that it is in a synchronized state. These are the error logs from SSMS. How do I trace the cause of the problem?
Error: 5901, Severity: 16, State: 1.
Nonqualified transactions are being rolled back in database for an AlwaysOn Availability Groups state change. Estimated rollback completion: 0%. This is an informational message only. No user action is required
Error: 18400, Severity: 16, State: 1.
One or more recovery units belonging to database failed to generate a checkpoint. This is typically caused by lack of system resources such as disk or memory, or in some cases due to database corruption. Examine previous entries in the error log for more detailed information on this failure.
The background checkpoint thread has encountered an unrecoverable error. The checkpoint process is terminating so that the thread can clean up its resources. This is an informational message only. No user action is required.

Why do I leave my DB in Restoring State after attaching to the instance? Could not this fire a redo activity on Transaction Log?
Or, How does sql server undo all uncommitted transactions on active vlf during recovery?

We have mirroring setup for 5 dbs, 4 of which are synchronized and 1 which is in "synchronizing" state on the principal and "restoring" state on the mirror. Mirroring for all dbs has been working fine for the past several months and we have a witness that has allowed automatic failover in the past without problems.
This database has several bulk inserts performed throughout the day and am sure there is some latency due to the size of these transactions.
Not sure as to why this is happening all of a sudden, but the db in question has been in this state for the past 12 hrs. I checked the mirroring status on the principal and it states that it is "synchronizing: data is being transferred from principal to mirror", but the mirror server states that db is in "restoring" state. Can anyone suggest as to how I can get the database on the mirroring server to get back to "mirror, synchronizing/restoring..." state? Or suggest on how I can troubleshoot this?
Thanks in advance.

Hi there,
I'm new to this forum but was wondering if you could advise me on getting the DB back to an accessible state. I tried restoring the DB but unfortunately I don't have enough disk space. The error message appeared instantly informing me of the lack of disk space. Now it says its in (Loading state) and I cannot access the DB. Is there anyway I can manually change it back??

I'm testing log shipping locally and had it running between two boxes. I tried to remove log shipping so on the primary I unchecked "Enable this as a primary database in a log shipping configuration" as per another thread. The primary stopped after a bit but the secondary never came out of the (Restoring...) state.
I'm obviously missing a step that needs to be run on the secondary because what I did wouldn't work if site A exploded but I can't figure out what the last step is.
Thanks,
Jeff

When performing a tail log backup to an online database through SSMS, the database is placed in restoring state. Is there a proper procedure to take the database out of restoring state after the backup is completed?

I am new to this environment and was asked to ensure that the transaction log shipping for SQL 2005 on W2K3 boxes is working properly. I noticed the db's on the secondary server are show "Restoring..." I am not sure if these were set up in No Recover Mode or Standby Mode. I have no access to the secondary db's. I get an error message when trying to access them (error 927). Monitoring was not set up initially and as you may or may not know can't be turned on after the fact...unless you delete the job and start over.
My question is is "Restoring..." normal and what does it indicate?

I have a database called PrimaryJunk that is being log shipped to another location, secondary database is secondaryjunk. From PrimaryJunk to SecondaryJunk logs ship and apply fine with no issues. So I figured lets make sure that I am able to perform a role change and swap the roles and that is not working well. My original primary db is stuck in restoring state.
I manually backed up the active transaction log on primary server by performing a transaction log backup with the option 'backup the tail of the log and leave the db in restoring state'
MS site has the same step but mentions NORECOVERY. I am not sure if my step above does that automatically. http://msdn2.microsoft.com/en-us/library/ms191233.aspx
Wonder if thats the reason my original primary db is still in restoring state. any idea?

The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.

SQL Configuration: Two 2003 Servers (OS Std ver) with SQL 2005 (Std ver) configured for db mirroring. (The servers aren't clustered.)
Web.config configuration string is using "ServerA".
If we fail Server A, then Server B will change roles to "primary" in about 20 seconds (we have confirmed this via SQL Mgt Console). BUT...our web app is still pointing to Server A and doesn't seem to know there is a fail over. SO - how can I make the web app aware of the failure?
Server A and Server B aren't in a cluster - and I understand a cluster's virtual server would be referenced in the connection string. Is there a way to make the web app automatically switch to Server B (without a cluster configuration)?
From what I understand, the cluster configuration would require Ent Ed. of OS and SQL and a big fat check!!
Thanks.

I did setup a Mirrored Database. Connecting from it using ADO.NET works well. It goes to the Mirror if the Principal fails.
But ADODB does not work. I get the error following error:
80004005 Invalid connection string attribute
When trying to connect to the DB in case the principal failed and the mirror is active. (MyProductiveDB is in failover state)
What do I do wrong?
Here is the code:
ADOConn = New ADODB.Connection
ADOConn.Open(CS)
CS is my Connections-String:
"Provider=SQLNCLI.1;Data Source=MyProductiveDB;Failover Partner=MyMirror;Initial Catalog=MyCat;Persist Security Info=True;User ID=MyUser;Password=xxxxxx;Pooling=True;Connect Timeout=5;Application Name=MyApplic"
Remark: When I try to add "Network Library=dbmssocn" to the connection String, I get the same error, even if the Principal is active.
Your help is very much appreciated.

We have a mirror setup, with a third server that needs to be linked to this mirrored setup. The link server setup only allows you to specify the primary server. How will the linked server setup know what the secondary server is? Thanks

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.

I have two 64bit SQL Server Std servers that will be principal and mirror. I also need to stand up a witness. I already understand that the witness can be any version of SQL Server, but can the witness server be 32bit given the principal and mirror are 64bit?

Hi,
We are migrating all dbs to SQL2005 one by one and now planning for a database mirroring. I would like to know the following:
1. My database(one main production) size on the primary is around 1TB. So having said that we are goin to have a db mirroring, do i need to have the same hardware requirements on the mirror also?? do i need 1TB space on the mirror server also? is there anyway it can use the same hardware that primary is using?
2. For the high availability configuration in mirroring, we are prefering to have a witness server too. Does the mirror server need to have same h/w configuration as the primary(64 bit, AWE, etc). Can the witness be a 32bit, 4 Gigs RAM?
Could anyone please answer the above and that will be very helpful. This is a bit urgent.
thks,
Mani

Does anyone know how to configure a mirrored pair as a linked server on a 3rd instance?
Say I have a mirrored database on two servers: PRIMARY and SECONDARY.
I want to create a linked server on a 3rd machine that allows me to access the database on the mirrored pair.
This is what I'm using:
EXEC master.dbo.sp_addlinkedserver
@server = N'MIRROR',
@srvproduct=N'',
@provider=N'SQLNCLI',
@provstr=N'Server=PRIMARY;FailoverPartner=SECONDARY;'
select count (*) from mirror.pubs.dbo.authors
and it works fine if the database on PRIMARY is alive. however when the mirror has failed over to SECONDARY and PRIMARY is no longer available, I get the following when I try to query the database via the linked server:
OLE DB provider "SQLNCLI" for linked server "MIRROR" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "MIRROR" returned message "An error has occurred while establishing a connection to the server. When
connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 10061, Level 16, State 1, Line 0
TCP Provider: No connection could be made because the target machine actively refused it.
As far as I can tell, it doesn't try to contact SECONDARY at all. It seems like SQL Server is ignoring the FailoverPartner attribute.
If I switch PRIMARY and SECONDARY in the connection string (ie @provstr=N'Server=SECONDARY;FailoverPartner=PRIMARY;') then it works when SECONDARY is online, but not when the mirror has failed back to PRIMARY.
Any ideas?
Piers.

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 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?

As an 'SA' I thought that you have permission to do anything on the server. Running an update command from Query Analyzer is throwing this error:
SQL Server 2000 SP3
Server: Msg 18456, Level 14, State 1, Line 1
Login failed for user 'sa'.
The table is in the dbo schema.
Has anyone seen this error before?

Hello all,
I have a question concerning the ridiculous quagmire of SQL Server licensing…
How is SQL Server licensed when used to store session state information? Is MS claiming that this is an end user use of SQL Server functionality? Or, can we be realistic and say that I need a server license plus a device license for each web server?
Personally, I like everything about SQL Server except the licensing. Management at my company has already said that we’ll most likely be moving to either Firebird or Postgres after they found out how much it would cost to move from SQL 2k to SQL 2005. If MS wants us to buy processor licenses for SQL state servers, I guarantee we’ll be doing something else there as well. I wonder if Microsoft has any clue how much business they’re losing. Not just in SQL Server, but in their OS business as well.
