According to Microsoft, if you need to change the subnet for the clustered servers, you will need to either edit the registry or reinstall virtual SQL Server.
Does any one know which registry key(s) store the subnet information? I was reviewing the clustered key but was able to find the key for the IP address only.
Thanks ...byyu :D
We are going to use SQL Sever change tracking. The problem is that some of our tables, which are to be tracked, have no primary keys. There are only unique clustered indexes. The question is what is the best way to turn on change tracking for these tables in our circumstances.
View 4 Replies View RelatedWe have a SQL 2014 AlwaysOn availability group running on two Windows 2012 R2 servers that are in the same subnet. We created a new server in a second subnet, installed SQL, joined the server to the Windows cluster, added a new IP resource for the new cluster, and performed the other remaining steps to add a new AG replica to the SQL instance on this new server. When we try to move the core cluster resources to the new node to test failover, we get an error. Here's the command we've been using:
Move-ClusterGroup "Cluster Group" -Node node3
and it returns the error: The operation failed because either the specified cluster node is not the owner of the group, or the node is not a possible owner of the group...I've checked the ownership of the cluster groups and the cluster resources and it looks like they are set appropriately:
>Get-ClusterGroup | Get-ClusterOwnerNode
Cluster Object Owner Nodes
---------------- ---------------
Available Storage {}
Cluster Group {node1,node2,node3}
SQLAG {node1,node2,node3}
[code]....
We've double-checked that all IP resources are in the right subnets and that the dependencies for the Cluster Name resource and the Listener Name resource are set appropriately. I'm not sure what else to check since the PowerShell commands seem to indicate that node3 is an owner of the appropriate resources. What other things need to be checked or if the ownership being checked isn't the same as what PowerShell is checking?
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

Hi All,
Just want to know if we can replicate data (Transactional Replication) from a clustered servers (server A and Server B are active-passive clustered running SqlServer 7) to another server C running SqlServer 7.
If yes, how to go about doing this. Any white papers, KB articles or books out there which will walk through the steps to do it.
Appriciate any help.
Thanks,

I've been asked to write a script to monitor whether a clustered server is up and alive and if so which node it's actually running on. Apparently there's been some problems of failover to the passive server without anyone knowing that it happened and they want to know. Any suggestions?
View 9 Replies View RelatedIs it possible to use registered servers feature in clustered environment and with different versions of Sql server like 2012 & 2014.
View 0 Replies View RelatedHello,Being a bit of a SQL Server novice, need some advice with the followingsituation.Server A and Server B have SQLServer 2000 based databases. The vendorof the application/system has implemented their own replication processto ensure the 2 databases are in sync. However, there is no clusteringwith virtual IP addresses implemented. So to an external client/db, itis 2 identical databases with the same name on 2 distinct servers.We need to develop an application that will reside on a networkedserver C and with SQLServer 2000 as well. While most of the tables inthis database are self contained, around 10 tables will have to bemirror copies of the same tables from either Server A or Server B.Question, how do we implement subscription based replication on top ofa redundant database, when no clustering is implemented? So, inessence, when Server A is alive, the database on Server C willperiodically (or on change) replicate the 10 tables from Server A. WhenServer A is not alive, it needs to do same from server B. (When bothserver A and B are alive, it is acceptable to get data from either,since they are synchronized internally).Any alternate suggestions on achieving this functionality are welcometoo. If SQL Server 2005 has some capabilities that may address thisproblem, that is a consideration as well.Thanks

I have 4 servers, 2 each for application (Dev & Prod)
DEV 1 & DEV 2 are standalone servers
Prod 1 & Prod 2 are Windows Clustered Servers.
From one application to other we do Distributed transactions. Dev 1 - Dev 2 or Dev 2 - Dev 1 can start DTC and working fine,but issue comes when Prod 1 - Prod 2 or Prod 2 - Prod 1. I get error message OLE DB provider "SQLNCLI" for linked server "xyz" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 3
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "xyz" was unable to begin a distributed transaction.
I have tested Dev 1 - Prod 1, Dev 1 - Prod 2, Dev 2 - Prod 1, Dev 2 - Prod 2 everything is working fine only Production servers are causing issue.
I enabled all settings needed for DTC on Cluster MSDTC service but no luck.
In our lab we have 2 clustered instance of Sql server 2018R2 as follows
Virtual Server Name
IP SqlVir 10.1.1.6
SqlVirDr 10.1.1.12
The Data is SqlVir is replicated manually every day to SqlVirDr.
We had to change the Virtual Server name of SqlVirDr to SqlVir so that all dot net applications accessing SqlVir could continue to access the database without changing the application string.
For that purpose I deleted the computer name SqlVir from the domain and its IP 10.1.1.6 from DNS. Then I went to the failover cluster manager of SqlVIrDr right clicked the Sql services selected the properties and changed the DNS name from SqlVirDr to SqlVir.The applications then could access the data.However when I changed the network IP address from 10.1.1.12 to 10.1.1.6 the Sql services was found to be down.
Perhaps the procedure I followed in deleting the computer name from domain and the IP from DNS was wrong.What exactly is the steps that I should follow to achieve the above objective.
We have an Sql Server 2008R2 Clustered production instance by name 'ProdVir' configured in 2 nodes(Active-passive) withWIndows Server 2008 R2. We also have another clustered instance as disaster recovery by name 'VirDr' configured again in another 2 nodes of Windows Server 2008 R2. Every day morning there is mainatenace plan which backups all the database in production and another maintenace plan in the disaster recovery server 'VirDr' which restores the backups into the VirDr instance.
I would like to know that in an eventuality of a disaster in the clustered production instance of 'ProdVir'. could we rename the the instance VirDr(meant for disaster recovery) to ProdVir and also change the Ip addresses accordingly so that the application programs do not have to change the details for the datasource in the connection strings.
Hi,
We've had this issue for awhile, but I have not been able to find a resolution for this. We have 2 identical servers (hardware & software) set-up: IBM x3850-(88633RU) running Windows Server 2003 Enterprise x64 (5.2.3790 SP1 Build 3790 R2). Server A was running SP1 (Build 9.0.2047) on a 3-node active-passive-passive failover cluster. Server B was running SP2 + Hotfix KB933097 (Build 9.0.3152) on a 2-node active-passive failover cluster. Both these servers are heavily utilized, and when originally installed with these versions of SQL Server Enterprise 2005 experienced no issues during or post-install. The original install of SQL 2005 Enterprise on both these servers had the Cluster Group Selection "Data files" setting changed to "M:MICROSOFT SQL SERVER" so that all system dbs and binaries would be installed to that location. On Server B where SP2 had already been applied, the update was downloaded on May 1, 2007, well after the GDR issues which had been plaguing SP2 releases was supposed to have been resolved.
Our problems began the night when we tried to apply hotfix KB933097 on Server A, and cumulative update packages 1,2,3 on Servers A & B, as well as catch-up the same SP2 and hotfix packages on other non-clustered servers where default system db locations remained the same. On all servers other than Servers A and B, the installs proceeded smoothly and without issue.
On Server B, which was already running SP2 + Hotfix KB933097, we tried installing Cumulative Update Package 1 (Build 9.0.3161) on the primary node. The install proceeded until the following errors were encountered:
"[Microsoft][SQL Native Client][SQL Server]Cannot find the object 'dm_exec_query_resource_semaphores', because it does not exist or you do not have permission."
"[Microsoft][SQL Native Client][SQL Server]Cannot find the object 'dm_exec_query_memory_grants', because it does not exist or you do not have permission."
After this, the setup finished with the message "Product: Microsoft SQL Server 2005 (64-bit) - Update 'Hotfix 3161 for SQL Server Database Services 2005 (64-bit) ENU (KB935356)' could not be installed. Error code 1603. Additional information is available in the log file C:Program FilesMicrosoft SQL Server90Setup BootstrapLOGHotfixSQL9_Hotfix_KB935356_sqlrun_sql.msp.log."
We rebooted the server and tried several times to reinstall the hotfix as sa and as the database service account with full windows and sa credentials, each time with no success, and rebooting between retries. All other components were installed successfully. We were hesitant to try uninstalling the hotfix, since it was unable to be removed successfully in previous attempts. However, when I connected to Database Engine using Management Studio, I found that the version of SQL being reported was in fact Build 9.0.3161! Everything also appeared to be running properly.
I tried to to Google the answer, but could only find information as applied to SP1 when system dbs master and mssqlsystemresource were located on different locations (http://support.microsoft.com/default.aspx?scid=kb;EN-US;918695 ). I had already verified that all system dbs, including the ones mentioned, were originally and currently located together on M:Microsoft SQL ServerMSSQL.1MSSQLData.
Finally I contacted a fellow DBA who advised me to continue installing all the other hotfixes, and then compare all SQL files against other servers where the install succeeded to ensure all system files were updated correctly (matching file sizes and datetime stamps). Since we were depending on a fix in Cumulative Update Package 3 to fix a critical log-shipping security issue, I went ahead with the rest of the installs, getting the same error with each package, rebooting between each install.
We found after the final install that the mssqlsystemresource files in the M:Microsoft SQL ServerMSSQL.1MSSQLData
directory were in fact updated after each install with a new timestamp, and that all files in C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBinn matched on both file size and timestamp. The log-shipping security issue we were looking to fix also appeared to be resolved by the last update.
On Server A, which was running SP1 (Build 9.0.2047), we installed the same SP2 package as we had on Server B with no issue. We rebooted and then tried to apply the same Hotfix KB933097 (Build 9.0.3152) that had been applied successfully on Server B and found to our surprise that the same errors were being generated here as well. We continued to apply the rest of the hotfixes so that both servers matched software updates. Comparing the above directories showed that files seemed to have been updated, even though database services appeared to be not installed.
It looks like we now need Cumulative Update 5 hotfix package in order to deal with WMI alerting issues, but I'm afraid to apply it until we have a known resolution for the past errors.
Since this issue was supposed to be resolved by SP2, I'm not sure why these post-SP2 hotfixes should fail. It seems to me to be an issue of the directory location of the system files which is in question.
I can post the hotfix log files as well, if anyone is interested in seeing them.
Any help would be greatly appreciated. As well, does anyone have any idea when SP3 is scheduled to come out? I really don't like applying hotfixes which are usually untested for general purposes, and it seems Microsoft is delaying this in favour of releasing SQL 2008.
I am working on a app that stores IPs in a sqlsvr 2k db.. all is well and good but when doing some reports on the data, I need to include/exclude certain ip ranges/subnets.

I have created two tables. table one has the following fields,
Id -> unique clustered index.
table two has the following fields,
Tid -> unique clustered index
Id -> foreign key of table one(id).
Now I have created primary key for the table one column 'id'. It's created as "nonclustered, unique, primary key located on PRIMARY". Primary key create clustered index default. since unique clustered index existed in table one, it has created "Nonclustered primary key".
My Question is, What is the difference between "clustered, unique, primary key" and "nonclustered, unique, primary key"? Is there any performance impact between these?

Hi there, I have a table that has an IDENTITY column and it is the PK of this table. By default SQL Server creates a unique clustered index on the PK, but this isn't what I wanted. I want to make a regular unique index on the column so I can make a clustered index on a different column.
If I try to uncheck the Clustered index option in EM I get a dialog that says "Cannot convert a clustered index to a nonclustered index using the DROP_EXISTING option.". If I simply try to delete the index I get the following "An explicit DROP INDEX is not allowed on index 'index name'. It is being used for PRIMARY KEY constraint enforcement.
So do I have to drop the PK constraint now? How does that affect all the tables that have FK relationships to this table?
Thanks
What is the easiest way to remember the definitions of clustered and non clustered indexes.
View 9 Replies View RelatedI have a really super slow stored proc that does something simple. it updates a table if certain values are received.
In looking at this the matching is done on the Primary Key, which is set as a Clustered index, looking further I have another constraint, that sets the same column to a Unique, Non-Clustered.
I am not sure why this was done, but it seems to be counter productive. I have read only references to Which one is better on a primary key, but not can their be both and if it is "Smart".

Hi Folks,I'm very new to SQL Server. I have a home network. My primary connectionto the internet is using "Gateway 1" a linksys router, of which, my serveris a LAN node on that router. I have another LAN node connecting to the WANnode of the "Gateway 2" a wireless USR router to use with my laptop. Usingthe wireless laptop, I am on a different subnet than the Server. I'd liketo make a connection to the server through Visual Studio.net but I can'tseem to do it. I'm using TCP/IP with a port different than the default port(let's call it port 2110, even though it's not). I do have port forwardingon Gateway1 and I've tried everything from just the server internal IPaddress, the external IP address, IP address with port designation, URL withport designation, nothing seems to work. Any ideas?Thanks!Rick

We are running SQL Server 2012 Enterprise on Windows 2012 R2. We have set up A WSFC with the primary Node in our East Coast Data Center and the Secondary Node in our West Coast Data Center each node is in a dfferent subnet. Since we have high latency between the sites we run in Asynchronous mode with manual failover only. My quesion concerns Quorum, everything I read would indicate we need a third node (odd number) (e.g. a fileshare Witness) with only the file share and the primary node having a vote...What I don't see is any need for a file share if we can only do manual failover.

I have a web server that is on our DMZ subnet and I have a sql 2014 database server with Always on Availability Groups that is on our internal domain subnet.The failover cluster is on the internal domain subnet as well. I am trying to connect a web application, that is working off the .net 2.0 framework, to an SQL Server 2014 database using the Always on Availability Group Listener.
The connection strings works perfect with the named instance of the sql server but when I try to use the Availability Group listener it timed out. I did some research online and was led to believe that increasing the connection time would resolve it. I did that and got a different error pertaining to a successful connection but an error occurred during the login process (Provider: TCP Provider, error: 0 - The specified network name is no longer available.)
I just want to connect to an Availability Group Listener on the domain subnet. I have rules in the firewall to allow all services for the IP of the Listener. I switch back to the named instance of the same server and it works flawlessly. I have also connected to the Listener while running the application on the same subnet as the sql server without an issue. I have tried the IP instead of the Listeners name and still received the same error on the DMZ subnet. I'm running on Windows Server 2012 R2 on all servers.
