Hello,
I've been running SQL 2005 Enterprise SP1 for some time. After installing SP2, I miss the "Database Mirror Monitor"-Feature. Where is it? Did MS kill the feature?

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.
I have configured a Mirror with Server A as Principal, Server B as Mirror. I can Remote Desktop into both machines and see the Launch Mirror Monitor option in the Tasks list from the Object Explorer. I do not, however, have the option when logged in from my desktop Object Explorer. In each instance, I log into OE using the SA login. Both machines are on sp2. I have seen others post similar problems but have not found anyone with a resolution. Any help is greatly appreciated.
Thanks,

I have an exact copy of a database on 2 instances of SQL server (dev and test - dev is restored from test).There's a view that I select top 1000 rows from that runs extremely slow on both instances (DEV and TEST) however on DEV the execution plan specifies that I'm missing an index however in TEST the execution plan does not specify that I'm missing an index.

The SQL server perfmon counters are missing from one of my MSSQL 7.0 servers - they do appear in others just fine.
Can anyone tell me what is wrong and/or how I can add the counters? I have seen archieve notes on this topic but can't access them for some reason (page appears blank when I click on link)
I am using perfmon to remotely monitor the problem server. My login has sysadmin permissions and is an NT admin. on both the server and the monitoring client. The login account for MSSQL server and SQL Agent services are both sysadmins.
Many thanks
I need help in anyone with this problem.
I started out with trying to get to know the existing SQL Servers (6.5 and 7.0). I am missing some Performance Monitor objects (ie SQL Server: Buffer Manager, SQL Server: General Statistics, etc). I am surprised that it is missing.
A typical SQL Server setup:
* NT 4 with SP6
* SQL Server 7 (standard) with SP2
* 2gig Mem
* Over 50gig HD
Does any of you ever have this problem? Any solutions? Any answer would be greatly appreciated.
Thanks.

Im missing all SQL Server counters in the Performance Monitor
and have looked at article: http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/Q196/6/57.ASP&NoWebContent=1
but this article refers to SQL 7...I have 2K with SP3 and MS03-031
How can I get my counters ? thanks
I am running performance monitor on a number of servers without any problems, however on one server, when I select SQL Server Log, It does not show a list of the available db's under the instances.
Other counters, say under SQL Server appear fine.
The server is running SQL 6.5 sp 4, I am running the monitor from an NT 4 Workstation, with full administrator rights on the server.
Thanks in advance for any help
(I have tried MS Tech Sup Online and can find no hits for this one)
Hi
I have a curious problem. I have a development environment SQL Server 6.5 sp 5a and a production environment sp 4
When I view the performance monitor in the development environment I can see the SQL Server object counter but on the production environment I can see all object except sql server objects.
What could the problem be ? Add chart on the production server shows me all ojects other that SQL Server and the same is not true for development !
In sql server 2014 , many performance counters are missing .I need " Buffer cache hit ratio " under "sql server :buffer manager " .Is there any way to get it back or removed form sql server2014 ?

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.

If I'm on a remote machine, meaning a computer not in the WSFC cluster, and I open SSMS 2014, point it to a SQL Instance, and open activity monitor:
1. I get all the panes and charts except % Processor Time.
2. Then, if I authenticate to the cluster's domain by mapping a drive with valid domain credentials, I'm free to put performance counters in the Perfmon - - - but SQL Activity Monitor shuts down with“The Activity Monitor is unable to execute queries against server SQL-V01INSTANCE1..Activity monitor for this instance will be placed into a paused state.Use the context menu in the overview pane to resume the activity monitor.
Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))(Mscorlib)”
3. Of course, the Activity monitor can't be resumed via the context menu. Removing counters and closing the perfmon do not work. I dropped the mapped drive and rebooted the machine. That brought back 95% of the information in the Activity monitor.
4. Further experimentation showed that any mapping of drive shares present on the SQL Server to the computer running SSMS cut off functionality of the 'overview' pane in the remote machine's SQL Activity monitor -- the monitor that had been trying to watch the server offering the shares.
I have a mirred database and have snapshot created from the mirroed database. I can do data selecting from the snapshot. But when the pricipal server is down , I can re-active the mirroed database.( I did succesfully upto this). Then I need to restore the database from snapshot and which failing with following error message.

All,
I have created an asynchronous database mirror and a snapshot of the mirrored database similar to what is described in the following article:
http://msdn2.microsoft.com/en-US/library/ms175511.aspx
The article says that once you create the mirror that "At this point, new client connections can be programmatically directed to the latest snapshot."
My question is, how can you programmatically direct connections to the latest snapshot?
Does anyone have a suggestion, or know what the article is getting at? We will use SQL Server Reporting services to query off of the database snapshot.
Thank you,

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
I am using MS SQL 2000 Standard, is it possible to create a mirror database in SQL 2000? If so, would you suggest how to do this. Thanks! I am a newbie about this.

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,
anyone has the experience to solve this?

Hi
While a database upgrade schema changes were being made the Mirror became disconnected will this recover itself when it reconnects or will it be the case that we will have to copy the db files to the Mirror and set it up from scratch.
It was set up as a synchronise mirror
Hi
I tried to setup service broker to fail over to a mirror database. After the target database failed over, the message I send stays in sys.transmission_queue with no error in transmission_status. I check the mirror server log and I see the following.
An exception occurred while enqueueing a message in the target queue. Error: 15581, State: 3. Please create a master key in the database or open the master key in the session before performing this operation.
The database has the master key because its a mirrored database? Did I have to do something extra here

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,
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,
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?

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.
We have a database with AlwaysOn enabled, where the database is getting mirrored using AlwaysOn to a secondary node in a two node cluster. Now we want to set up a DR site for that database in a different data center.
So trying to analyse what technologies. We can use for setting up the DR for that database. Can we use mirroring / replication or what's the best way of setting up DR on that database.
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......
All,
We have SQL 2005 db mirror configured with a witness server for high availability. Node 1 is the principal and Node 2 is the mirror. A nightly job creates a snapshot on Node 2. The snapshot is used for previous day reporting queries. We have now been asked to present another copy of the database for near-time reporting. I thought about possibly adding a peer-to-peer replication as part of my environment but was hoping to see what everyone else out there is doing.

Hello All,
I've tried to replicated exactly what it says in the online documentation. At the end of the post are the SQL statements issued.
1. Enable encrypted outbound connections on the primary server
2. Enable encrypted outbound connections on the mirror server
3. Enable encrypted outbound connections on the witness server
4. Enable encrypted inbound connections on the primary server
5. Enable encrypted inbound connections on the mirror server
6. Enable encrypted inbound connections on the witness server
7. Set mirror''s partner to the primary
8. Set primary''s partner the mirror
9. Set principals witness.
Every step run''s normally,but why can''t auto failover.
