Failover Partner Keyword Not Recognised With OLEDB
May 10, 2007
Hi
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.
SQLNCLI works with no issues at all.
Connection string code samples included.
--Code that does not work
Code Snippetconnstring = "Provider=SQLOLEDB;network=dbmssocn;Data Source=Server1SQLInst1;FailoverPartner=Server2SQLInst2;Initial catalog=mydb;INTEGRATED SECURITY=SSPI;"
Code Snippetconnstring = "Provider=SQLNCLI;network=dbmssocn;Data Source=Server1SQLInst1;FailoverPartner=Server2SQLInst2;Initial catalog=mydb;INTEGRATED SECURITY=SSPI;"
Any help is appreciated.
Thanks

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

I need to connect to mirrored SQL servers (Developer Edition) using OLE DB, I tried both OLE DB and ODBC, but it doesn't work
I used connection ODBC string:
Driver={SQL Native Client};Server=10.0.1.161;Failover Partner=10.0.1.162;Uid=test;Pwd=test;Database=TestDB
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
SQL Server service pack 1
Is there any way how to connect from OLE DB?
Thanks

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.
EXEC master.dbo.sp_addlinkedserver
@server = N'MIRRORLink',
@srvproduct=N'',
@provider=N'SQLOLEDB',
@provstr=N'Server=primary;FailoverPartner=mirror;network=dbmssocn;',

Hi All,
I have a tricky one for you...
1. I create a custom log provider on machine A.
2. I deploy the signed assembly to the../../DTS/90/LogProviders directory & the GAC on both machine A & machine B.
3. I create a new package on machine A & go to enable logging for this new custom provider: I find it in the drop-down list of providers, and I can add it successfully.
4. I create a new package on machine B & go to enable logging for this new custom provider: I find it in the drop-down list of providers, but I can't add it. I get the following error:
'...failed to create log provider...the log provider type "_" specified for log provider "_" is not recognized as a valid log provider type. This occurs when an attempt is made to create a log provider for an unknown log provider type. Verify the spelling in the log provider type name (package)."
Any ideas anyone??

1. Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk.
2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode.
3. after fail over done to 2nd secondary node what mode in production(readonly or read write).

We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?
Are we missing a service pack on the client?
Thanks,
Kimball

I am databinding a dataset formed from a stored procedure,(all done on page_load).
However, the reference to the column name is not recognised with the following error being returned.
Column with name "CalcVal" was not found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: Column with name "CalcVal" was not found.Source Error:
Line 152: chartCommand.Fill(chartDs);
Line 153: Chart1.DataSource = chartDs;
Line 154: Chart1.DataBind();
Line 155:
Line 156: }
This worked before deployment and the other controls which are bound to data using stored procedures seem to work. However, these other data sources are all sqlDatasoure controls.
Any suggestions would be helpful.
I have found issues relating the to user ID and password which seems to depend on whether the web server and data server are the same machine or whether they are remote from each other.
cheers-jim.

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?

Hi!
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: '')
Security settings it seems are set accurately.

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

Hello,
Am I reading it wrong or can I have a developer edition as a partner?
http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx Please take a look at the Database Mirroring and SQL Server 2005 Editions section.
Anyone knows?
Thank you.

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 have similar problems as in
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1020144&SiteID=1
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
and on second machine
HOST/Machine name
HOST/Machine name.Domin.com
MSSQLSvc/Machine name.Domin.com:1433
any Clues?

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.

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 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.
I found info about modifying the MSDTC security settings under "component services" and did so. I made sure everything was allowed. However, the result was the same. Does anyone have any other idéa about what could cause this problem?
PS. The package works fine if I set up both databases on the same physical machine...

I am trying to implement a band search on my web site (concert listings) and would like it to behave a bit more intelligently than a standard match on the band name.
At the moment I have a stored procedure that just selects every show that features a band with exactly the same name as the search term. What I'm now trying to do is when the user enters a band name containing the '&' character I would also like to search using the word and 'and'. For example, if they search for 'Rise & Fall', they should get details on all shows featuring 'Rise & Fall' OR 'Rise And Fall'. Is it possible to do this within my stored procedure?

Greetings, I am a php developer, and running a little bit out of deadline in a project. Can someone provide me with a VERY simple way to implement search by keyword in C#? I have already implemented a search page (according to firstname, lastname etc) that works on a drop down menu (where you have the option to choose seach by keyword) . So, I need to change something in my SQL query to make this work. I already knew from my SQL experience that the simplest and probably the SLOWEST and MOST UN EFFICIENT one was using LIKE. I don't mind using it but I can't since I will end up having something close to that: SELECT * FROM users WHERE keyword_entered LIKE @keyword; (or '@keyword) which does not work. however SELECT * FROM users WHERE keyword_entered LIKE 'somename%'; does work! I guess the trick is in putting the % after the keyword. ( I would have done that in php by putting the entered keyword in a string and than add to it % and pass it to the SQL query and I dunno how to do that in .NET)any ideas?
