DSNLess Connection With Failover To A SQL Server 2005 Cluster
Nov 20, 2006
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.

Curious on how this will work.. if i install sql 2005 standard edition on one virtual server.. to a fixed disk (actually 2 fixed disks.. one for C, one for D).. then install another 2005 standard edition on another virtual server.. do i just rerun the setup and suddenly the failover cluster option will NOT be greyed out?
Can anyone comment on this?
Thanks in advance.

Hello all,
I am intsalling SQL 2005 in an activepassive cluster. The OS is Windows 2003 with SP1. Everything installs OK but the sql server service cannot start afterwards. There are many access errors in the Security Event log - see example below - and numerous "SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. " errors in both the SQL and Application event logs. I have tried installing SQL in both mixed mode and under Windows Authentication and get the same errors. I can install SQL 2005 outside of the cluster on both nodes. Other items of note: This was a SQL 2000 cluster. I uninstalled SQL 2K, the virtual name was changed (IP remained the same) and the DNS entry was updated to reflect the new name. Early in the installation process - 3 or 4 days ago - I got a few errors about the Server Principal Name had to be updated but when I do a setspn -l the both nodes are listed and the entries look fine, though there are no entries for the sql service (MSSQLSvc). Not sure if there should be entries for the virtual name, but there aren't any for either the old or new name. Does the new virtual name need to be added to AD? Here is the security error - Event ID is 560 and it looks like there's a problem with Remote Access and is generated when trying to access either node:
Category: Object Access
Type: Failure Audit
Event_ID: 560
User: NT AuthorityNetwork Service
Object Open:
Object Server: SC Manager
Object Type: SERVICE OBJECT
Object Name: RemoteAccess

Process ID: 1516
Image File Name: C:WINDOWSsystem32services.exe
Primary User Name: CM-OHCO-DS006B$
Primary Domain: SWNA
Primary Logon ID: (0x0,0x3E7)
Client User Name: NETWORK SERVICE
Client Domain: NT AUTHORITY
Client Logon ID: (0x0,0x3E4)
Accesses: Query status of service
Privileges: -
Restricted Sid Count: 0
Access Mask: 0x4
One other informational message that may be of use - looks like there's a problem with dll's for remote access, though this isn't pertaining to SQL:
The description for Event ID ( 0 ) in Source ( srmservice ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: srmservice error: 0, Started the agent (srmagent.exe)..

I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?

I noticed in installing a SQL2005 failover cluster instance,that it is not necessary to install on both servers. Installing on the primary node automagically installs to the secondary node. Does this constitute a COMPLETE install? It all seems to work. BUT this process does not intall client pieces (SSMS, for instance) on the secondary node. If you want that stuff there, do you then go to that box and just do a client install?

Hi we have a two node windows 2003 x64 cluster, each running a SQL 2005 instance. I've added a new node to the cluster and am now trying to set up a new instance of SQL 2005 on the new node (node c). During the install i am getting a failure just after the stage where you choose the features to install. I'm selecting SQL database engine with Failover Cluster. When i click next i get a message which states:
"The drive specified cannot be used for program location. Program Files must be installed on a valid local disk available on all cluster nodes. The valid values are"
I've read a number of articles about possible causes for this and i've checked all the suggested causes but none of these have made a difference. The cluster disk resource is healthy and can be failed between all nodes in the cluster. No errors are generated. I am using an account which has domain admin rights and I can access all admin shares on all nodes. Some of the articles i have referenced are here:
http://support.microsoft.com/kb/907261
http://support.microsoft.com/?kbid=913815
http://blogs.technet.com/mbaher/archive/2007/03/23/clustering-sql-2005-and-administrative-shares.aspx
I've tried uninstalling all components etc but still i can't get it to work. The next step is rebuilding the server completely so does anyone have any suggestions?
Any suggestions would be greatly appreciated.
Thanks
Chris

I am tying to set up an SQL 2005, SP1 failover cluster on a new set of hardware. Everytime I try to run the install, I get this error
TITLE: Microsoft SQL Server 2005 Setup
------------------------------
Setup failed to start on the remote machine. Check the Task scheduler event log on the remote machine.
I've gone through this doc (http://msdn2.microsoft.com/en-us/library/ms189910.aspx) and checked all of the applicable cautions:
I don't have an antivirus package running.
All of the SQL setup pre-checks run fine.
I have a SQL Group created, with the shared drive as a resource.
NBT is disabled on both heartbeat NIC's.
NBT is explicitly enabled on both external NIC's.
While I do have DDNS running, just to be safe I've pre-created an A record for my SQL VR.
Both nodes are registered in DNS and Setup correctly finds the second node.
In the Application event log on the second node (the one failing...), I get MSI Installer 'Install Started' successes (and sometimes I even get "Product: Microsoft SQL Server 2005 -- Installation completed successfully.")
I am running the install as myself, a Domain Admin and am explicitly added to the Administrators group on both servers.
Remote Registry is running.
Task Scheduler is running.
There is plenty of space everywhere.
All of the Admin shares are enabled.
The node I am running the install from is the owner of all of the cluster groups and resources:
Cluster group
MSDTC group
SQL group
This is all that is in my setup log:
Microsoft SQL Server 2005 9.00.1399.06
==============================
OS Version : Microsoft Windows Server 2003 family, Enterprise Edition Service Pack 2 (Build 3790)
Time : Tue Nov 06 16:45:52 2007
Task did not appear to start on machine: \ERLEW01B: 267013
I'm at a total loss and I'm getting very frustrated...

I am using MS Access as a frontend to SQL Server tables on 2 differnt machines. One machine uses Windows Authentication so DSN connections have been no problem. The other machine is using SQL Authentication and I am having issues with DSN connections to these tables because of the User ID and password required by SQL. I use the SQLConfigDataSource function for creating the DSN but the UID an PWD parameters do not work for the SQL authentication connections. I have found that apparently these parameters are not supported by the API.
At this point I have tried to figure out how to do this through a DSNless connection but am new to ADO and have really no idea how to establish the connection let alone how to link the tables through the connection. I am much more comfortable with the DSN approach but at this point I am stuck.
For the sake of arguement lets say the following is the environment.
Server1 (Windows Authentication) has the following tables
Table1
Table2
Server2 (SQL Authentication UID=user PWD=password) has the following tables
Table3
Table4
With this environment how do I establish DSNless connections to both servers and then make Access think that all four tables are linked tables. I want the to be treated as linked so that I can still use the design view as well as view data in the tables in Access without need to use the SQL Enterprise manager for testing purposes.
Any help/guidance would be greatly appreciated. Also if this is not the appropriate venue for this question I am sorry.

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:

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 --

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
Note: Service Pack is not installed.

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.

In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.
I removed it from the cluster but it is still there in the registry etc on the node I was working on.
I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.
I definitely don't want to remove one of the servers from the cluster.

if it is supported to install Reporting Services on both the active and passive nodes in an SQL Server Failover Cluster and use the non-active node as a warm standby?We have relatively simple reporting requirements so the idea would be that if Node 1 went down, we could just repoint our users are Node 2 temporarily. Both reporting services instances would be configured to target the same SSRS database running on the SQL Cluster.

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 I just set up a new cluster and everything was working. Now when I try to test failovers like unplug the public network card etc...
The cluster group fails over correctly but my data and log array's dont failover.
So I unplug the network cable from node 1 (active) the cluster group with the IP, name, and Quorum disk fails over to node 2 but the other groups sql data and sql log stay on node1 and dont failover.
Any ideas?

Hi all:
I was wondering what will happend to the transaction when the cluster failover from one node to another?
In my case the database is in node-001 and I need to restart the server on node-001. So I need to have the database failover to node-002, so I can work on node-001. During this process, will it effect to end-user?

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.
