URGENT: The Command Failed Because The Database Mirror Is Busy!
Mar 30, 2007
Hi,
Mirroring has been working fine on 2 identical servers. We even tested failover and that worked....but today something happened (still investigating) and suddenly the Principal is disconnected and we cannot force failover with:
ALTER DATABASE [LeoCTI] SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS
Error: The command failed because the database mirror is busy! Try again later!
How can I bring the principal back online? It won't let me do anything, won't let me turn off mirroring etc. etc.
HELP PLEASE!
Thanks

Hi everyone,
A relatively simple question but I have no been able to find an answer.
We have a SQL Server mirror Active/passive with High availability. So the usual Witness with failover.
However, we are using the Mirror server for reporting and letting the users query without limit. We sometimes have problems (slowness) with the Principle server and I'm wondering the following.
If the mirror server in high availability mode is maxed out will this affect the principle server because it takes longer to commit the data on both servers?
It seems obvious but I would like a clear response.
Thanks.

Process to create snapshot failed (twice per day snapshot of the database is being created for some people to work on). Morning snapshot worked fine but the afternoon one failed. The snapshot is being created from Mirror database. I used this code:
CREATE DATABASE [DB_snapshot] ON
(name = N'DB',filename = N'D:SnapshotDB.SQLSnapshot' )
,(name = N'indexes',filename = N'D:SnapshotDB_indexes.SQLSnapshot' )
AS SNAPSHOT OF DB
And the error message i get
Msg 1823, Level 16, State 6, Line 1
A database snapshot cannot be created because it failed to start.
Msg 1823, Level 16, State 7, Line 1

What might be causing this error? Mirroring seems to be working OK. status is "Synchronized"

We are migrating our databases from MS Access to SQL Server 2005 and using the SQL Native Client ODBC driver.
We also use a reporting tool called Actuate. Some of our Actuate reports use multiple datastreams to build the report.
When I run an Actuate report having multiple datastreams I get the following error message from SQL Server:
Error generated by the connected data source. Connection is busy with results for another command.
Is there a configuration setting in SQL Server to enable processing of multiple result sets?
Thanks.

I have looked at other threads regarding errors similar to this, but I think mine is a bit different.
I am using SQL2005 Standard Edition and my application is coded with C# using ADO.Net. OLEDB connection is used. The error occurs when the application has only one thread accessing the database. It does not happen consistently, so it is very puzzling.
I am wondering if anyone could offer any tip to diagnose this.
Thanks in advance!

Hi, I'm new to c# and sql2005 express. I'm getting an error on the simplest of activities. From C#, i create a database, create a table, then try to delete the database and get a database busy error. I think its because sql has some connections to the database its not releasing. I have already tried closing the connection, disposing of the object and forcing garbage collection for the c# app to no avail.
can someone explain to me wat is going on?
Here is the only function i am calling for c#. I pass in T-SQL command strings such as 'Ceate Database myDB','Create Table myTbl','Drop Database myDB', etc.. :
private bool ExecuteSQLNonQry(string sqlStr)
{
SqlConnection myConn = new SqlConnection(ConnectionString);
SqlCommand SqlCmd = new SqlCommand(sqlStr, myConn);
try
{
myConn.Open();
SqlCmd.ExecuteNonQuery();
myConn.Close();
return true;
}
catch(Exception e)
{
MessageBox.Show(e.Message.ToString());
return false;
}
}

What will be best procedure for the following situation.
Heavy traffic database on daily basis. G growth every day. so Full backups every nights are needed.
Vendor recommends not taking Log backups but copy just log files over other location. will this help avoid degrading the performance during business hours.
if i don't take log backups, i am not able to recover Point in time if needed.
also log files can then grow faster and then i will have to shrink it more often.
what are risks and suggestions.
Thanks,

Hey Folks,
I have inherited a project from a co-worker who has had a family tradegy, and I am trying to get up to speed with her project.
We have an SQL server 7 database which is getting backed up every night (by SQL itself) into a .BAK file. I need to know if it is possible to restore this file from the command line (a DOS prompt.) I know (or think I know) how to do it from within SQL Enterprise Manager, however the specific needs of this project require it be done from a command line on the machine.
I really am not an SQL guru...I don't even think I qualify as "knowing what I am doing" at all, so any advice you can offer will be greatly appreciated. This is kind og urgent, so your thoughts are welcome!
Thanks!

Hi
I am using SQL 6.5. I have a master table which is referenced by more than 35 tables. When I try to
delete a record from the table, i am getting this message
Msg 431, Level 16, State 0
Unable to bind foreign key constraint. Too many tables involved in query.
SQL 6.5 maximum 31 foreign key references. I was wondering is there any way to delete those
records. (i don't want to drop the foreign constraints)
SQL 7.0 supports maximum 63 foreign key references.
Thanks in advance
Moorthy.

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,
Racer-D

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

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
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.

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,
