Neither The Partner Nor The Witness Server Instance For Data...
Jan 27, 2006
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.
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
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?
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.
The problem: One server sees the witness, one does not. If the dbs are active on the one that doesn't see the witness and I shut that server down everything works as it should. However, if the dbs are active on the server that sees the witness and I shut that one down the mirror does not take over because it can't see the witness and form a quorum. It throws Event ID 1438 every 20 seconds complaing "The server instance Witness rejected configure request...The reason 1451, and state3, can be used for diagnotics by Microsoft...."
The scenario: I finished setting up a mirror in a WORKGROUP, by going through the GUI and then at the choosing not to start the mirror. That allowed me to modify the NETBIOS names and change them to IP addresses in order to get around the FQDN requirement that I can't fulfill since the servers are in a workgroup. They are in the same subnet and can run SQL queries against each other.
When I query sys.database_mirroring from the database servers I get this on the good server: mirroring_witness_name mirroring_witness_state_desc ---------------------------------------------------------- TCP://155.17.92.63:5022 CONNECTED TCP://155.17.92.63:5022 CONNECTED
And this on the bad server: mirroring_witness_name mirroring_witness_state_desc ----------------------------------------------------- TCP://155.17.92.63:5022 DISCONNECTED TCP://155.17.92.63:5022 DISCONNECTED
here's are the results from sys.database_mirroring_witnesses database_name principal_server_name mirror_server_name safety_level safety_level_desc -------------- -------------------------- ------------------------- ------------ ------------------ dbadmin TCP://pscdaltpscom20:5022 TCP://155.17.92.65:5022 2 FULL dbtest TCP://pscdaltpscom20:5022 TCP://155.17.92.65:5022 2 FULL
Oddly, the server that I created the mirror from registered itself with it's NETBIOS name even though I told it to use an IP address. However, that's the one that is working properly. I think this might be a red herring.
Does anyone have any ideas why my second server can't communicate with the mirror? Any clarifications I can make? I have been completely unable to find a step-by-step guide to creating mirror databases outside of a domain...so if someone knows of one please point me that direction.
I am unable to add witness server to my mirror configuration. my error log is throwing error'Connection handshake failed. The certificate used by the peer is invalid due to the following reason: Certificate not found. State 89'.
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?
the Mirror Server is not connected to the Witness Server.
Mirror Server and Wtiness Server are instances on one server.
I get this error:
" 2007-06-28 17:08:12.77 spid23s The server instance Witness rejected configure request; read its error log file for more information. The reason 1451, and state 3, can be of use for diagnostics by Microsoft. This is a transient error hence retrying the request is likely to succeed. Correct the cause if any and retry."
In the SQL Profiler for the Witness Server I get "An error occurred while receiving data" Error 64.
In the witness server logs is nothing depending on this.
The connection between the witness and principal and the mirror and principal are all right. I have created User logins with certificates on the same way on all instances.
We've been running a mirrored database (using certificates since we don't have a domain) and it's all working well. Last week we decided to add a witness for automatic failovers, but for some reason I just can not get the witness to connect to the Partner2 server.
See screenshot here
Please help me troubleshoot this - I re-created the endpoints / users / certificates but it's still not working. Where can I get more information on what exactly the problem is? Can I test the endpoints somehow?
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
missing witness server information and the fail-over is broken suddenly? 4:00am no maintenance job. I have one sql job on 10pm for backup on database transaction log only.
I can see the primary have problem then perform fail-over to mirror database, the auto fail-over was broken.
I re-build the sql mirror is OK , but i want to find the root cause.
Windows application event was full when there have many failed event, i have increase log size for application event. Â
We have 2 data centers, site 1 and site 2. Â Site 1 is generally our primary, and site 2 is our Disaster Recovery (DR) site. Â I want to setup a SQL instance to have extremely high availability. Â Therefore I was looking at using DB mirroring, with synchronous data writing, high-safety and auto-failover. Â This requires the usage of a witness server.My problem with this setup, is that if the witness and principal are both at site 1, if site 1 goes away (power failure, asteroid impact, lol, anything else that would be a *true* DR scenario), then there is no failover to the mirror server at site 2. Â However, if you put the witness at site 2, anytime the WAN link between site 1 and site 2 has an issue, the DB will auto-failover to site 2. Â Is the reason for the recommendation of the witness being at the primary site because the thinking is that WAN link failure is likely more common than a *true* DR scenario that takes out all of site 1?
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
Here's my situation:I have an ODBC DSN setup for Timberline Data (An accounting packagethat uses pervasive.sql) on my sql box. I set up a linked server usingthe supplied timberline odbc driver. I have two sql instances setup,the default instance and a named instance. On the default instance,the linked server works great no matter who is logged in using it (allauthentication is NT integrated). However on the named instance onlythe NT account that the MSSqlserver$NAMED service is logged in undercan utilize the linked server. All others get a ODBC error:"error 7399: OLE DB Provider 'MSDASQL' reported an error. AccessDenied. OLE DB error trace [OLE/DB Provider 'MSDASQL'IUnknown::QueryInterface returned 0x80070005: Access Denied.]."Far as i can tell, both instances are setup the same, except that oneis the default and one is a named instance.Why the different results for the default instance vs a named instance.Any ideas?Thanks
I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..

i have installed SQL client instance on my Desktop "Machine-A", and i used to connect to SQLServer2000 running on another "Machine-B" by using valid username and password.
i created a DTS package and i used to run it. im very confused how the communication happens between the two machines and which process run where and which initiates which and which machine allocates waht resources. im really interested to know all these things. if any one know plz help me out.
Hi all,Here is the table and DML statmentsCREATE TABLE [jatpartnerMst] ([rowid] [int] ,[partnerid] [int] NULL ,[mcstat] [int] DEFAULT (1), -- 1 Pending ,2 Approved[sf] [varchar] (20))INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(1,1,2,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(2,1,2,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(3,1,2,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(4,1,2,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(5,1,1,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(6,1,2,'inactive')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(7,1,2,'inactive')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(8,1,2,'inactive')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(9,2,2,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(10,2,1,'active')INSERT INTO [jatpartnerMst]([rowid],[partnerid],[mcstat],[sf])VALUES(11,1,2,'active')What I wish to find is the latest record on the top and it's otherrecordse.g If partnerID 1 is changed it goes to the bottom of the table , atany given time I am interested only in max(rowid) for a partner withstat 1 or 2I am using this queryselect * from jatpartnerMst where rowid in (select max(rowid) fromjatpartnermst where mcstat in (1,2) group by partnerid,mcstat )This query does not give me the latest.On using this queryselect * from jatpartnerMst where rowid in (select max(rowid) fromjatpartnermst where mcstat in (1,2) group by partnerid,mcstat )order by rowid descThe partner's two records get seperated .

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
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 Jon Macy
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
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.
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.
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?
