SQL Server Failover:
Jan 22, 2007
I have to figure out a way to handle a failover in SQL Server 2005. I was reading a few articles about it.
1. Do I need to do anything in application layer to let a failover occur in SQL Server 2005
2. I have a web site that connects to a production server, the connection string is defined in web.config. If I implement Mirroring in SQL Server 2005, and when failover occurs, shouldn’t I change the connection string to point the application to the new server?

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).
4. how to rollback to production primary ,will change data in secondary will get updated in primary.

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

Hi all,
We are the studying the possibilty of implementing SQL - Clustering for
Failover server.
Are there any third party tools readily available.
Any suggestion or checklist ??
Any suggestions or comments will be appreciated.
Thanks and have a great day.

I'm looking at a setup where they have server1 and server2 in a mirroring relationship with automatic failover.Â
Server1 is the principalThey are using transactional replication to replicate asingle databse to server3 is AWS.Distribution database is on Server1All Agents (log reader, snapshot, distributor) run on Server1Server2 has not been set up for replication...My understanding is that in this set up you would normallly place the distribution database on a separate server and enable publication on the mirror, Server2.
What happens if they failover? Replication would stop, and presumably records added while the mirror is the active database would not be marked for replication?How would they recover? Failback and reinintialize

We have 2 nodes window Server 2012 R2 and SQL Server 2012 Enterprise Version cluster setup. We can switch roles and Node to one node to another and revert back to previous node with out any issues. But we are facing when one Node is restarted. We could not restart that Node in cluster Service start in Failover cluster Manager. Error Details is displayed as below inside double code."Cluster node NODE1 could not to join the cluster because it failed to communicate over the network with any other node in the cluster. Verify the network connectivity and configuration of any network firewalls."
I checked windows firewall. windows firewall is all of in Node1, Node2, SAN and DC.I have disabled and enabled the Internal and private network of Node 1. I have validated the cluster. it is showing no error though.
Node1:
Public IP: 10.10.0.11
SubNet Mask:255.255.255.0
Default Getway: 10.10.0.1
Prefered DNS: 10.10.0.10 (Ip of DNS)
[code]....
Private Network: Not configured.pinging to each other ip is successful from one node to another.

We have a mirror setup, with a third server that needs to be linked to this mirrored setup. The link server setup only allows you to specify the primary server. How will the linked server setup know what the secondary server is? Thanks

Greetings,
Ever since our sql2005 A/P failover cluster failed over to the 'B-passive node', I have a failing SSIS scheduled job with a 'missing component' error. While verifying services in computer management and sql surface area config, It appears that the SSIS service is not available because its not listed therefore cant be started. I have examined both nodes and the primary "A-active node' shows the SSIS service but the passive node unlisted. The server has failed over before during normal scheduled updates and sevice pack installs however this is the first occation we have not failed back to the primary node for normal operation. Any ideas or clues would be appreciated.

Hi,
Here is my testing environment:
Database server: SQL Server 2005 Developer Edition with SP1
Application: An application developed by Visual Studio 2005 using C# (.Net framework 2.0) and ADO .Net 2.0.
Principal server: computerA
Mirror server: computerB
Witness server: computerC
Mirroring mode: High availability with auto failover
Connection String:
Data Source=computerA;Failover Partner=computerB;Initial Catalog=test_mirroring;Persist Security Info=True;User ID=sa;
Code used for failover:
while (true)
{
thisDataSet = new DataSet();
try
{
thisConnection = new SqlConnection(connectionString);
thisAdapter = new SqlDataAdapter(SQL, thisConnection);
thisAdapter.Fill(thisDataSet, name);
break;
}
catch (SqlException e)
{
thisConnection = null;
thisAdapter = null;
thisDataSet = null;
}
}
Test Case:
(Part A) At the beginning of the test, computerA was in principal role. I started my testing application and connected to computerA without any problem. Then I disconnected the connection of computerA to the network by unplugging the network cable of computerA. The failover of database from computerA to computerB was carried out without problem. computerB was in principal role at that time. The application was pending for about 45 seconds and running again without problem. Then I re-connected computerA to network and it became the mirror server. computerB was still in principal role. Up to this point, all works fine, but the problem was coming next. (Part B) I disconnected computerB from network, database failover occurred, computerA became principal again. But my application cannot switch the database connection to computerA and then kept pending. Then, I re-connected computerB to network. It was surprised that the application switched the database connection to computerA successfully at that point.
My questions:
1. I think Part B is abnormal, isn€™t it? The application should be able to failover from computerB to computerA, because it works fine when failover from computerA to computerB.
2. Is there anything wrong in my code leads to the abnormal behavior of the application in Part B.
3. How can I achieve Part B? Any suggestion or idea?
Thanks for your attention.

I have 2 Windows 2003 r2 servers with a SQL failover cluster installed across the 2 node. Generally I have been running off node1 with node2 as the failover partner. I have purchased the correct licensing for noe1 and from the following I do not need to purchase a license for node2:
Failover clustering is a process where the operating system and SQL Server 2005 work together to provide availability in the event of an application failure, hardware failure, or operating-system error. Failover clustering provides hardware redundancy through a configuration in which critical resources are transferred automatically from a failing machine to an equally configured server to help ensure continuity of service.
When doing failover support, a server is designated as the passive server. The purpose of the passive server is to absorb the data and information held in another server that fails. A passive server does not need a license if the number of processors in the passive server is equal to or less than the number of processors in the active server. The passive server can take the duties of the active server for 30 days. Afterwards, it must be licensed accordingly
http://www.microsoft.com/sql/howtobuy/activepassive.mspx
My questions are:
1) If I switch my cluster instace to point to node2 for testing node2 in case of a failover, would I need to purchase another licence ? This means I am not doing the repointing because of an 'event of an application failure, hardware failure, or operating-system error' ? Can you please provide information from MS ?
2) How are SQL Licences bound to the windows install in a SQL Server failover cluster configuration ? For instance if node1 legitimately fails due to an 'event of an application failure, hardware failure, or operating-system error' and you failover to node2. Then you think, stuff (forget about) node1 as I have 1 set of licences for SQL Enterprise already and therefore can run with a legitimate licence on node2. Can you please clarify ?
3) I have heard that only one server needs a license in a failover cluster. Then how does this fit in with any of the questions from above:
'The passive server can take the duties of the active server for 30 days. Afterwards, it must be licensed accordingly' ?
In the event of a legitimate failure, node2 would be running off the license purchased. So why are MS restricting the use of it for 30 days ?

Hi all,
The following query that uses a linked server is giving me the error message below after I initiate a failover (ALTER DATABASE Northwind SET PARTNER FAILOVER). I have SQL Server 2005 SP2. I think that without the service pack there is another error too.
The query is run from a database other than northwind of course.
select * from DualLink.northwind.dbo.Test1
Please note that:
without a failover it works perfectly
it always work if I try to run it a second time - only the first time it fails.
it fails the first time for each of the open connections. A new connection that was open after the failover will work fine.
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
The linked server is defined as
EXEC master.
dbo.sp_addlinkedserver
@server = N'DualLink',
@srvproduct=N'',
@provider=N'SQLOLEDB',
@catalog=N'northwind',
@provstr=N'Server=(local);FailoverPartner=MyIPAddr;'
EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname = 'DualLink',
@useself = false,
@locallogin = 'sa',
@rmtuser = 'sa',
@rmtpassword = 'MyPwd'
Thanks,
Avi

I have a production failover cluster running SQL Server 2000 at SP3that I want to upgrade to SP4. I do not have a test failover clusterto test with so I need the install on the primary server to work thefirst time. Per the information I have I just install the patch on theprimary server and it will install both on the primary and on thesecondary.However, I remember when I did the initial install and it failed. Thefirst problem traced to the fact that the install uses temporary filesunder the profile of the installing administrator and the id had neverlogged into the second server so the install failed on creating thetemporary file. The was a second problem that related to an OS featurethat had to be off for the install to work.If anyone out there has done this upgrade and remembers encountering aproblem and its fix/workaround I would appreciate a head up warning.Thank you-- Mark D Powell --

We have a clustered sql server 2000 installation on windows 2000. Werecently lost the select into/bulkcopy option from a database. Themost likely candidate appears to be a failover just before - afterthis happened the setting disappeared. Any ideas?ThanksTom

Hi there.
I´m running some tests in a database with Mirroring and without Mirroring. As expected there is a performance hit using Database mirroring.
The tests i´m running are just simple functions inserting and updating the database, and then counting the number of sucedeed inserts and updates in a time interval.
My question here is: What if i use Sql Server failover mechanism?
I know that failover time will increase and management is more complex, but what can i expect in terms of performance ?

Hi All,
We're planning to install a Server 2005 Failover Cluster and I'd like to find more information about licensing, etc.
Basic questions:
- What is the best O.S. to run? Win 2003 or the new 2008? And what version (datacenter, enterprise)?
- Since I'm going to use 2 machines, will I have to pay for 2 licenses (sql and windows - two lic. each)? Or just 1 license, since just 1 machine will be the active server?
This is for some web applications, so, web environment.
Any help?
Thank you!

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 principal€™s witness.
Every step run''s normally,but why can''t auto failover.
I used the following Script:

I have installed 2 node windows Fail-over clusters successfully. But QUARUM Configuration is not appearing in Failover cluster manager instead "Witness: Disk (Disk Cluster 4)". I have also configured quarum configuration from Quarum "Configure Cluster QUARUM Settings". I have attached the snapshots of windows cluster configuration. Is it the issue or not. I have not got any warning and error during cluster validation while installing Windows failover cluster. I am assuming it is okay and i can move ahead to installation of SQL Failover cluster setup.
Products used for installation in Virtual Machine:
Windows Server 2012 R2
SQL Server 2012 R2

We are not able to failover the AG to secondary replica. The process gets timed out and AG goes to resolving mode. Had to reboot the box in order to switch the AG back to primary node. We even rebuilt the whole AG from scratch but the issue remains.
Failed to bring availability group 'xxxx' online. The operation timed out. Verify that the local Windows Server Failover Clustering (WSFC) node is online. Then verify that the availability group resource exists in the WSFC cluster. If the problem persists, you might need to drop the availability group and create it again. [SQLSTATE 42000] (Error 41131). The step failed.
Not much information is available in the logs.

Hi,
We have configured two SQL Server 2005 in a cluster (without Witness).
We have severals ASP (using ADO) that are connecting to SQL Server 2005 with SQL Native Client in a DSNLess connection String :
driver={SQL Native Client}; server=MAINMAIN; Failover Partner=BCKUPBCKUP; uid=log;pwd=pwd;database=MyBase
When using this connection string, the connection to MAIN is alrigth, but when we simulate a unavailability situation on "MyBase" or on the entire MAIN instance, the new connection are joining the MAIN and not the BCKUP SQL Server.
We tryed several Connection Strings including Failover_Partner, Initliag Catalog instead of database... but no one succed in joining the BCKUP SQL Server.
I precise that the DNS on the PC that connect to SQL server is configured and both MAIN and BCKUP are resolved in command line or in explorer.
Is there an other driver that must be used, or is there an other parameter to set in the connection string ?
Regards.

Hello All, I am trying the following script to upgrade SQL Server 2005 SP1 to SP2. I have an Active Passive cluster configuration. I have default instances of SQL Server. I am using the following script.
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /allinstances /quiet.
The sql server install fails to run. When I used the above command with just
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /quiet still the summary.txt file came with authentication success and that is all. I changed the above script and did
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /instancename=instancename of the cluster
This worked, however the install patched the passive node (DB engine, all the cluster unaware components) but failed to patch the DB engine on the Active node. I had to run the SQL Server sp2 install manually but still it did not patch the DB engine on the primary node
1. Can someone please help me with this issue as I want the unattended install to work. so it installs both active and passive node. I will post the final output and also the ADS script to do this as a bonus if this works.
Here is the summary.txt file.

IF you need to change the IP Address of a SQL Server Failover Cluster instance, here is the steps:
1. Open up Failover Cluster manager.
2. Expand the MS Cluster Instance that your SQL Cluster instance resides on.
3. Expand Services and applications.
4. Select the SQL Server Service.
5. In the main window pane (Middle Screen), you should see your SQL Server Cluster name, expand the plus to the left of it.
6. Under your SQL Server Cluster name, you should now see an 'IP address' section, right click on it and go to properties.
7. In the properties pane, you can change your IP address by entering a static IP.....or assigning a DHCP enabled IP.

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