Mirroring :: Unable To Drop Endpoint With Name Mirror Server
Jul 16, 2015
I have created a Endpoint with "Mirroring Server" on the mirroring instance. Due to the keyword server i am not able to drop the endpoint now.
Also am not able to configure a mirror in a windows workgroup also( the two systems principal and mirror are under same network ). I have followed many ways as per msdn articles and other blogs.
I am not able to connect to the mirror server.Â
I have tried giving the ip addr and the port no, also the computer name:port no, computername.local:port no etc. Both the systems are running on sql server 2008 only
I always get the error as Connection cannot be established to the destination.
(I have also enabled the ports in firewall by creating inbound and outbound rules)
The issue probably lies in NAMING server address i guess.

Hello everybody,
I'am currently testing a MSSQL 2005 mirroring implementation with automatically failover.
1 principal server ====> Server A
1 mirror server ====> Server B
1 witness server ====> Server C
When server A fails Server B becomes Principal. ( which is the general idea ) This is working perfectly.
The problem is when i try to connect to the mirror Server B ( actually the new principal )
I use the .NET connection string with the failover parameter ( even without the parameter ) the connection fails.
( the general error : unable to connect, or connection property has not been initialized )
Data Source=ServerA; Failover Partner=ServerB;Initial Catalog=DBMTest;uid=dbuser;pwd=dbpassword;
This connection property works fine when server A (original principal) is online.
When i run the SQL profiler with the mirror db as profile, i dont see the traffic.
So you think the mirror server has a network problem or was not connfigured for remote access.
i thought that also, but when i create a 'stand alone - non mirrored' database the same application with the same connetion string ( well.....different db) works fine.
The problem must be in the whole mirroring implementation....... ( my idea )
Does anyone had the same problem, or better, doed anyone know how to solve it?
Hope to hear from you soon!
Thank you in advance!

Hi all,
Can a MIRROR server have mirrored databases on many instances or must all of the mirrored databases on a server reside on one instance?
This initial implementation worked fine:
PRINCIPAL ServerPROD1instance01 endpoint1430
MIRROR ServerDRinstance01 endpoint1440
WITNESS ServerZ endpoint1450
This second implementation (different PRINCIPAL server to same MIRROR but to a different instance)
PRINCIPAL ServerPROD2instance5 endpoint1430
MIRROR ServerDRinstance02 endpoint1440 <<same mirror server but different instance
WITNESS ServerZ endpoint1450
I know that you can only install one endpoint on each server. Does that mean that the endpoint can only resolve to one instance though?
The second implementation looks fine until the final step (start mirroring). I get the following error:
An error occured while starting mirroring
Alter failed for database 'test'
An exception occurred while executing transaction-sql statement or batch
The remote copy of database 'test' does not exist. Check the database name and resissue the command
I have created the test database in instance02 and rolled a log onto it. It is currently in recovery mode - waiting patiently for another log.....
I have read books online and 2k5 unleashed but can't see anything that relates to an implementation across mutliple instances on the DRmirrored servers.
Has anyone tried to do this? Can you confirm its possible?
Many thanks in advance...

I was told that if I wanted to setup mirroring between multiple instance on the same server that each endpoint had to be different number. Is that true? Or can I use the default 5022 for each instance?
Ex.
Server1Instance1
Use endpoint 5022
Server1Instance2
Use endpoint 5022
VS
Server1Instance1
Use endpoint 5022
Server1Instance2
Use endpoint 5023

I need to migrate my SQL server Mirror Database to a new server. my current setup is as below
1. server A principal (192.168.1.100)
2. server B Mirror   (192.168.1.200)
Now i have a new server (Server C) to replace server B as below
1. server A principal (192.168.1.100)
2. server C Mirror   (192.168.1.300)
My question is how to migrate mirror db to new server without any affect or downtime on principal server.
note: SQL SERVER 2008R2 EE(64BIT), Win2008R2 EE 64bit.

Hi everybody,
I have a mirroring set up for around 30 databases in a 64 bit - 2 powerfull servers scenario - wih latest sp2 + hotfix. Mirroring works perfectly most of the times but when the principal is getting busy during the busy period of the day all of a sudden the processor on the mirror jumps to 100% and stays there for a long time - there are no live databases on the mirror server - all the databases are in mirrored mode. The principal server processor is less than 5% all the time. The network load between the principal and the mirror is also in normal limits. The principal server is dedicated to SQL but the mirror has other things too but the other processes use up maximum 15-20% of the CPU and when I stop SQL Server in one of those moments when the CPU jumps to 100% everything comes back to normal so it's clear that the issue is SQL on the mirror.
Any ideas would be greatly appreciated.
Thanks,
Stefan

Hi!
I have setup a database mirroring session without witness - ServerA is the principal, ServerB is the mirror,. Each SQL Server instance is hosted on its own machine on sql2005 EE SP2. The mirroring is working correctly. If I submit to server ServerA command:
ALTER DATABASE MYDBNAME SET PARTNER FAILOVER
, ServerB becomes the principal, it means that mirroring works correctly.
My issue is with the SQL Native Client and a front-end ASP application (actually IIS 6.0 site) that needs to make use of this database. I have setup my front-end application to use SQL Native Client and specified the failover server in connection string. Here is the connection string that I am using :
PROVIDER=SQLNCLI.1;Server=ServerA,1433;Failover Partner=ServerB,1433;Database=MYDBNAME;Network=dbmssocn;Integrated Security=SSPI;
Everything works perfectly on my front-end application when ServerA is the principal. If I execute on server ServerA command:
ALTER DATABASE MYDBNAME SET PARTNER FAILOVER
, ServerB becomes the principal, and the failover occurs correctly on the database side. The problem is that my front-end application is not able to query the database on ServerB. The error appears:
Microsoft SQL Native Client error '80004005'
Cannot open database "MYDBNAME" requested by the login. The login failed.
This behavior my appication till I unload IIS 6.0 pool application. After that my front-end application becomes work correctly with ServerB.
When I swap server, I execute on server ServerB command:
ALTER DATABASE MYDBNAME SET PARTNER FAILOVER,
my IIS 6.0 application automaticly turn back to ServerA without any action on my side.
I am using SQL Native Client last version http://download.microsoft.com/download/2/7/c/27c60d49-6dbe-423e-9a9e-1c873f269484/sqlncli.msi (issued in February 2007). Has anyone experienced this issue? I'm thinking that it's a problem in the SQL Native client

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

I am just about ready to tear my hair out on this one, at this point you guys are my last resort! Wouldn't it be nice if I could go to bed and have an answer for me in the morning....
I've had a working HTTP endpoint using Basic Authentication over SSL for months in our development environment, but now I'm moving our application to a production server and I'd like to be able to use Digest Authentication in the clear instead so the processor doesn't waste cycles on the SSL decryption. I've spent hours fiddling with my endpoint to no avail.
This is the closest message relating to what I'm doing that I've been able to find: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1131251&SiteID=1
In my case, the SQL Server is joined to a domain that is entirely Windows Server 2003 - no Windows 2000, so support for Digest Authentication is a non-issue. I'm also explicitly doing a GRANT CONNECT on my endpoint to the domain user I'm using. Here is the top of my CREATE ENDPOINT DDL:
CREATE ENDPOINT [Kudos]
STATE=STARTED
AS HTTP (PATH=N'/Kudos',
PORTS = (CLEAR),
AUTHENTICATION = (DIGEST,NTLM),
SITE=N'echobase.kudosnow.com'
DEFAULT_LOGON_DOMAIN = N'kudosnow',
AUTH_REALM = N'kudosnow'',
CLEAR_PORT = 80,
COMPRESSION=DISABLED)
FOR SOAP (
I am debugging using wfetch 1.3... I can get this to work using NTLM Authentication; sending a GET to my endpoint with the ?wsdlsimple querystring parameter returns my WSDL just fine.
But Digest just doesn't want to work! If I remove NTLM from my AUTHENTICATION directive and try using Digest with wfetch or from my (PHP) web service consumer I get an HTTP 401 no matter what I do. I've tried fiddling with the DEFAULT_LOGON_DOMAIN, AUTH_REALM, and anything else I can think of.
The errors I am sporadically finding in the SQL Server error log are:
HTTP authentication failed. [CLIENT: 192.168.245.238] from source Logon
Followed by:
Error: 26026, Severity: 14, State: 1. from source Logon
I can't find any detail about the second error.
........
Just occurred to me that I've also been trying to view my WSDL directly in IE, and this is what's causing the SQL error to be logged, not wfetch - that's why it appeared sporadically.
So, wfetch isn't causing an 'HTTP authentication failed' error, but Internet Explorer is... maybe Digest Authentication isn't implemented correctly in wfetch?
Regardless... I'm still not able to authenticate from IE or from my client, but this may shed some more light on the issue.
Does anyone have any ideas?

The computer has to be as a workgroup machine to reflect our live server.
The user LMSEndPointUsers is a SQL Server Login
The user ostc-dev-001endPointUsers is a machine login
We have employed the Security class as per the information given in the SQL Server documentation with the intention of using the WS-Security headers that apparently are to be used when trying to authenticate using a SQL Server login.
----------------------------------------------------------------------------------------------------------------
Code used to connect and try and reciev the dataset.
string sUserName = "userName";
string sPassword = "Password";

Basically authorization is denied 401.
Hope someone can help here as have tearing my hair out.

I have two questions here.
Question 1:
If I am using Database Mirroring for my production database in SQL Serever 2005, can I do mirroring on the mirror database?
Principal Database -- Mirror -- Mirror A -- Mirror -- Mirror B
Can this be done?
Question 2:
Can I do 2 mirroring on a single principal database? If can, which mirror database it will goes when the failed over happen? can the other mirror switch to mirror the failed over database?
Principal Database -- Mirror -- Mirror A
-- Mirror -- Mirror B
Please advise. Thanks

The communication errors are between the witness server and sql servers. No errors between SQL servers. There seem to be no network issues and happen randomly.Â
Event id 1474 and 1479.Â
The mirroring connection to "TCP://witnesssrv:5022" has timed out for database "DB" after 30 seconds without a response. Â Check the service and network connections.Â

Hi, all.
here is the situation.
we designated one server as a mirrored server. this server will host all mirrored databases from different principles in different server using certificate.
1) Server A (Principle) Server B(Mirrored)
2) Server C (Principle) Server B(Mirrored)
I was able to set up mirroring between A and B. But unable to set up mirroring between C and B.
My question is "Can I grant connect on endpoint to two different host logins?"
For example, on the server B
I created two different logins for Server A and C in order to assign different certificates to two principle servers.
For Server A.
create login server_A_login with password = 'djkkajnxks';
go
create user server_A_user for login server_A_login
go
create certificate server_A_cert
authorization Server_A_user
from file = 'c:certificateserver_a_cert.cer'
go
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO [server_a_login];
GO
For Server C.
create login server_C_login with password = 'djkkajnxks';
go
create user server_C_user for login server_c_login
go
create certificate server_c_cert
authorization Server_c_user
from file = 'c:certificateserver_c_cert.cer'
go
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO [server_c_login];
GO
when I set up like this and try to start mirroring, I am getting error from server c saying, "the network tcp:serverb.corp.com can not be reached or does not exist"
But mirroring between server a and b is OK. I set up them first, then between c and b.
any ideas?
thanks,

Hi,
I've a very basic doubt about database mirroring. I did setup a database mirroring session with the help of SQL Server Management Studio between the server A (db1) and B(db1). When is stop database mirroring by using the command button "Stop Mirroring" available in the mirroring page of SQL Server Management Studio , the mirror database{ B(db1) } goes to state "Restoring...". After stopping the mirroring i'm not able to access the mirror database.
Can you please tell me how to bring mirror database B(db1) to operation mode so that we can start working with that database?

I have configured active passive cluster in production environment. And we also have a dr which we have configured with asynchronous mirroring with no witness. Currently active node(node
a) is in sync with dr. When failover happens and the second node(node
b) becomes active, the mirror is broken and goes to disconnected mode.
But when we failback again to node a mirror is connected again and is in sync again. In our setup we have active passive cluster and a standalone server as dr.

When I try to setup mirror on a SQLserver dbase using windows Authenticated login I get error:-
Login failed for user 'SERVERBAdministrator'. (Microsoft SQL Server , Error: 4060).The login connect string however on selection of SERVERB from SERVERA has a greyed out option for using Windows Authenticated login which clearly shows Username: SERVERAAdministrator.It is odd that the error coming back is showing SERVERBAdministrator on the rejection. (somehow the machines got swapped over in the authentication) The strange thing is if you use the SQLserver studio on SERVERA to connect to SERVERB using the object browser and Windows authenticated login it all works fine without errors. clearly the Mirror software is using some other means/privs of login to establish the connection.
The two machines SERVERA and SERVERB are in the same Domain (DOM1) but they are not using a domain user account.They are using Administrator user on both independent machines. The SQLSERVER install specified both Windows and sqlserver logins. The mirror is to use Windows authenticated login.Is there some login priv we are missing The sqlserver security has allowed this type of login......

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.

Hi guys , I would like to know what's the exactly results able to get in this following scenario.
Server A : Principal
Server M : Mirror
Server W : Witness
1) Firstly, disable server M, following by server W. So probably i will unable to connect to Server A eventhough it acts as a principal.
2) Next, if I enable either server M or server W , what will I able to get actually ? Is it the mirroring works like the article which written in Microsoft page ?(http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx#ETPAE)
At here, I get an error message and unable to continue the mirroring section. ( "Database EMS is enabled for Database Mirroring, but neither the partner nor witness server instances are available: the database cannot be opened." or "Database 'EMS' is being recovered. Waiting until recovery is finished." )
3) If I enable both server M and server W, the mirroring continue to work again.
Can I have any assistance on (2) issue? Thx for the assistance.
Best Regards,
Hans

To configure database mirroring
After connecting to the principal server instance, in Object Explorer, click the server name to expand the server tree.
Expand Databases, and select the database to be mirrored.
Right-click the database, select Tasks, and then click Mirror. This opens the Mirroring page of the Database Properties dialog box.
To begin configuring mirroring, click the Configure Security button to launch the Configure Database Mirroring Security Wizard.
but i do not see any "Mirror" Option in the "Tasks" menu.
Why ?

I have a 2 node cluster having 4 cores each wherein having 3 instances of SQL 2008 R2 enterprise comprising of 60 databases, 20 on each instance. I need to setup mirroring for each of the databases to a secondary server having 4 cores and 3 instances.
What i understand is that in this case the mirror server will be providing max of 512 worker threads and the 60 mirror databases would consume 240 threads.
What all needs to be checked for looking into the feasibility of going ahead with a async mirror setup as mentioned above.

(Microsoft SQL Server, Error:1412)".I am misplacing the Transaction Log backup file. Where I need to store that file?

Hi,
I've created the following endpoint on a local database as follows,
CREATE ENDPOINT Wrox_EndPoint
STATE = STARTED
AS HTTP
(
SITE = 'localhost',
PATH = '/Wrox',
AUTHENTICATION = (INTEGRATED),
PORTS = ( CLEAR ),
CLEAR_PORT = 81
)
FOR SOAP
(
WebMethod 'GetProductCountByProductModelID'
(
NAME = 'adventureworks.dbo.ProductByProductModelID',
SCHEMA = STANDARD
),
WebMethod 'GetProductModels'
(
NAME = 'adventureworks.dbo.GetProductModels',
SCHEMA = STANDARD
),
WSDL = DEFAULT,
BATCHES = ENABLED,
DATABASE = 'AdventureWorks'
)
When I try to add a web reference in visualstudio to http://localhost/wrox?WSDL I get a 404 error.
I checked the web service is created in sys.http_endpoints
I've also run the following to grant permissions
USE MASTER
GO
GRANT CONNECT ON ENDPOINT::Wrox_EndPoint TO [myDomainpaulm]
GO
Any ideas where I'm going wrong?
Many thanks Paul

We have an application running with a principal, mirror, and witness. If we bring the principal server down, it looks like failover occurs successfully, but the application is not able to access the database. If we bring the server back (so it is now functioning as the mirror), the application is now able to connect to the database. Why isn€™t the application able to connect without the mirror up? Any suggestions?

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?
Thanks,

Hi,
I have a table which I am unable to drop the index.
I tried to drop it via the TSQL and GUI interface (Indexes dialog box),
but when I clicked on table refresh, the index still there.
Below is the result after DBCC commands:
1. DBCC checktable(TB_LOCLoan)
Checking TB_LOCLoan
The total number of data pages in this table is 146542.
Table has 1596232 data rows.
Msg 605, Level 21, State 1
Attempt to fetch logical page 462136 in database 'DM_LOCLoan' belongs to object '1744009244',
not to object 'TB_LOCLoan'.
2. DBCC newalloc(DM_LOCLoan)
TABLE: TB_LOCLoan OBJID = 832005995
INDID=0 FIRST=60168 ROOT=642778 DPAGES=146542 SORT=0
Data level: 0. 146542 Data Pages in 18393 extents.
INDID=5 FIRST=463752 ROOT=463739 DPAGES=5304 SORT=1
Msg 2525, Level 16, State 1
Table Corrupt: Object id wrong; tables: alloc page 463616 extent id=463752 l page#=463752
objid in ext=-832005995 (name = -832005995) objid in page=832005995 (name = TB_LOCLoan)
objid in sysindexes=832005995 (name = TB_LOCLoan)
TOTAL # of extents = 18393
3. From Error Msg 2525, I have tried the suggested action
use DM_LOCLoan
go
select indid, name, object_name(id)
from sysindexes
where id=832005995
and distribution=463752
go
This query does not return any row.
I am running out of clue of how to proceed! Anybody come across this problem before?
I am very eager to solve this problem as the table is hanging here, I can't even drop it to recreate
and continue data loading.
Thank you.
Regards,
Joo Pheng
