Mirror DB Goes To In Recovery When Set Partner Is Issued
Mar 27, 2008
We have a pair of SQL 2005 SP2 with Rollups clusters. We have a series of DB's that we are migrating from an existing SQL 2000 cluster. I have scripted the process, however on one of the test DB's, it goes to "In Recovery" as soon as I issue the Set Partner statement. There are other DB's on the same cluster mirrored with no problems. As we have a bunch of DB's to migrate, I want to figure out what would cause it to start a recovery. After the initial restores are done, it is in "Restoring" for a status so everything works up to that point.
Thanks

We were having problems setting up the mirroring, so I did it via command lines. I found out the "alter...set partnership" command works on the mirror server going to the principal, but gets a 1418 error when going from the principal to the mirror. So if A is the principal and B is the mirror, A to B fails but B to A works. If I reverse it so that B is the principal and A is the mirror, B to A fails and A to B works. Any suggestions?
I'm having a problem with two mirrored databases, using SQL Server 2005 SP2, that autmatically failed over last night for unknown reasons. I was trying to fail them back over to the primary SQL server because it says the mirror is disconnected and out of sync. Other databases failed over too, but I was able to fail those back over without a problem. It's just these two. I removed the mirror from the secondary server thinking that this would allow me to restore the database back on the primary server, but that didn't help.
These two databases show a status of (Principal, Disconnected / In Recovery) and I still cannot do anything with the two databases on the primary server. When I try to pull up the properties for them, I get the following error:
"Database <Name> is enabled for Database Mirroring, but neither the partner nor the witness server instances are available: the database cannot be opened.(Microsoft SQL Server, Error: 955)"
I cannot delete, detach, Alter or do anything with the databases. If I could just delete them that would be fine so I can just do a restore, but I can't seem to do anything.
Does anyone know what I can do to resolve this problem.
We 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.
DB replication can set db recovery model to simple ,why db mirror can not  db recovery model to simple.
DB mirror must be set to full recovery model.
As far as I know, whatever db mirror  and db replication ,there is a log reader to read the log in the ldf file DB mirror and DB replication are almost the same principle to replicate the db to another db server.
I am using SQl Server 2012 Database Mirroring with around 40 gb as mdf and 1 gb as ldf. Now my ldf size increased . How to reduce ldf size while mirror enabled with mirror server and witness server. Can shrink the ldf with mirror enables.
Has anybody encountered this situation before? DB on SQL Server 2000 SP4 with trunc log on chkpt option turned on. Checkpoint trace flags were turned on but noticing no checkpoints are being done on one specific DB resulting into growing transaction log. No open transactions.
Will the database get locked if my ASP.Net application that is calling a stored procedure in which a HOLDLOCK for table1 is issued to SQL Server, suddenly crashes just after the stored procedure is called?
I do know Profiler can capture the sql scripts ADO.Net generated and do know can Capture SQL Scripts using SMO but how do i get the sql scripts when the command failed in order to do loging and bug fixing? eg:
private DataSet GetData() { try { SqlCommand command = new System.Data.SqlClient.SqlCommand("dbo.Test_TestParameters"); command.CommandType = System.Data.CommandType.StoredProcedure; command.Parameters.AddWithValue("@p1", 1); command.Parameters.AddWithValue("@p2", 2); command.Connection = new SqlConnection("data source=localhost;initial catalog=Test;user id=sa;password=;Connect Timeout=60"); command.CommandTimeout = 0; SqlDataAdapter dataAdapter = new SqlDataAdapter(); dataAdapter.SelectCommand = command; DataSet dataSet = new DataSet(); dataAdapter.Fill(dataSet); return dataSet; } catch (System.Exception e) { string issuedSql = GetIssuedSqlScripts(command); // !!! HERER can be command or connection Trace.WriteLine(issuedSql); throw e; } }
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?
I was trying to test mirroring and now would like to delete the mirror database but it says I need to remove database mirroring first. I deleted the endpoint and cannot figure out how to remove the mirroring. Can someone please help.
Every time I execute DBCC DBREINDEX (Table_Name, '',0)WITH NO_INFOMSGS the server hangs. No error messages in windows 2000 logs or in the SQL 7.0 logs.
The table is about 2 gig in size and the index is a clustered index on two fields.
The server has 1 gig of memory and the cache hit ratio, and cache flushes both look good. Any ideas? Any help would be greatly appreciated.
Hi.. My Finance user create a microsoft Excel OLAP file that connect to our SQL server. And I have created the same ODBC setting for every PCs.
But for a few PCs, I encountered the following error "Client Safety Options do not allow pass through statement to be issued to the data source" When trying to connect the OLAP file to SQL server after entering the same SQL account.

Hi, i am working with SMO object, At the time of accessing remote(LAN) database server I encountered the following message: "MirroringPartnerInstance" : Undefined error.
I m not able to figure out whats the exact problem is..
i had gone through the following link too but doesn't make any sense to me : msdn2.microsoft.com/en-us/library/microsoft.sqlserver.management.smo.database.mirroringpartnerinstance.aspx
All i understand is i need to set some property of mirroring partner.
Does any on have any idea how to resolve this problem
I've read that when this run's, it removes all db mirroring information on that db. What exactly does it remove?
Here's my senario:
We are using SQL 2005€™s db mirroring process. We are using the certificate method of authentication between the principle and the mirror db€™s.
My question is that when the ALTER DATABASE dbname SET PARTNER OFF is run, does it remove these certificate settings as well? In other words when I want to enable the db mirroring, will I need to recreate these certificates or just recreate the endpoints to use these certificates?
I have the following error during setting partner on mirror server Msg 1431, Level 16, State 4, Line 1 Neither the partner nor the witness server instance for database "masterserver" is available. Reissue the command when at least one of the instances becomes available.
The partner is available through telnet. I've also checked ports vai netstat and have no found errors.
There are two noteworthy erros in the error log at mirror server Error: 9642, Severity: 16, State: 3. and An error occurred in a Service Broker/Database Mirroring transport connection endpoint, Error: 8474, State: 11. (Near endpoint role: Target, far endpoint address: '')
We have a database,which has been mirrored.Also,We have an application which uses OpenRowSet to connect to this database.
Is it possible to set "Failover partner" in OpenRowSet connection string,so when we failover from Prinicple server to the mirrored database,The application still will continue to work?
Example:
select * from openrowset( 'SQLOLEDB', 'Data Source=Server1;Failover Partner=Server2;trusted_connection=yes;','select top 10 from Database1.dbo.Table1' ) temp
if server 161 is principal and server 162 mirror, it connects ok, but when I exchange server roles, connect fails (the error message is: Cannot open database "TestDB" requested by the login. The login failed. in LOGIN)
the connect string using OLE DB is:
Provider=SQLOLEDB.1;Persist Security Info=False;User ID=test;Password=test;Failover Partner=10.0.1.162;Initial Catalog=TestDB;Data Source=10.0.1.161;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False
error message is the same
when I try to connect using VS 2005 using connection string Database=TestDB;User Id=test;Password=test;Server=10.0.1.161;Failover Partner=10.0.1.162, it works OK
i have installed SQL server 2005 (on local - client machine) with SQL Native Client and also
i tried to set up mirroring having only principal and mirror. mirroring endpoints were easily created for both servers. when i try to add the partner name it responds with Msg 1418, Level 16, State 1, Line 1The server network address "TCP://machine1.domain.com:5022" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. On the log of machine1 i see, Database Mirroring login attempt by user 'NT AUTHORITYANONYMOUS LOGON.' failed with error: 'Connection handshake failed. The login 'NT AUTHORITYANONYMOUS LOGON' does not have CONNECT permission on the endpoint. State 84.'.
i am a sysadmin on both SQL Servers and have connect permission on both end points. Both the endpoints are in started state and listening to all IP's Both services are as 'Local System' As per what was mentioned in the above post to add a 'domain/machine$' user did not help. Tried using setspn.exe to add a new SPN MSSQLsvc/<HOST>:<MIRRORINGPORT> did not work. an ERROR comes 'not enough privileges' setup shows the following SPN only on both HOST/Machine name HOST/Machine name.Domin.com MSSQLSvc/Machine name.Domin.com:1433 SMTPSVC/Machine name SMTPSVC/machine name.Domain.com
Sincere Apologies for the cross posting. Did not realize that there is a specific DB Mirroring group and so posted initially in the High Availability group. Here is the original post
Hi
I am trying to test DB Mirroring connectivity and running into a road block. using SQLOLDB in my connection string the failover partner keyword seems to be not recognised when the failover occurs and the connectivity fails. The same however works with the SQL Native client driver.
Can any expert please let me know what I am doing wrong and what is the right connection string for the OLEDB one?. I also tried using different flavors of FailoverPartner (like Failover Partner, FailoverPartner etc) to make it work with OLEDB but still could not connect with SQLOLEDB provider.
I am getting this error while trying to setup mirroring. "Neither the partner nor the witness server instance for database "shop" is available. Reissue the command when at least one of the instances becomes available. (Microsoft SQL Server, Error: 1431)"
I am just using principal and mirror server, there is no witness server. I have tried fully qualified name and ip for the servers also. I can connect from the principal server to the mirror server using the management studio and it also creates endpoints on prinicipal and witness. But then gives me an error that it cannot find the instance of the mirror server and if I try again it gives the error above. I can also telnet to port 5022.
I have used -T1400 as the startup parameter.
I did the backup and recovery based on this link http://msdn2.microsoft.com/en-us/library/ms189053.aspx and the mirror server is in recovery mode now.
it is possible to create Linked server with Failover partner option. I can query when primary server and getting the error when I set the DB Fail over. I have tried with following script and also gone through different sources, but failed. Please see the script and error below.
I'm trying to run an SSIS package. The package runs on an SQL 2005 server on Win2k3 server. The package tries to connect to another win2k3 server with sql 2000 to retrieve some data. However, I recieve the errormessage shown in the topic.
We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.
Pages on a full recovery model database corrupted, need to ensure data loss is minimal for restore operation am thinking about restoring the latest full backup.
in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.Â
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue
We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?
