I an involved in a project that will have five sql server instances on an NT cluster.
I cannot find anywhere on Technet info on what happens when a single instance fails. Do they all have to fail over or just the failed instance. This is important so that we get the disk layout correct.
Can anybody help ? or point me to any docs on this.
Hi,
We have a new failover cluster (Windows 2003 SP1, Microsoft SQL 2000 SP4) with each node of the cluster hosting 7 SQL Server instances in a 2-node active-active configuration connected to a SAN. We are planning to move some SQL Server Instances(from existing stand-alone servers) into this Cluster. Any insight into the process of moving SQL Servers into the cluster would be highly appreciated.
Best Regards,
Himansu
Is it possible to have more than one instance of SQL Server on a failover Active/Passive cluster? What are the concerns/ramifications if that indeed is possible?

I am trying to install multi instances on my server cluster 2003 R2 Sp2. Because of the compatibility issues with my services I need to install both SQL 2000 and 2005. With 2000 I can easily specify the instance and servername. The server name can be the same, but the instance has to be different. Is this true for 2005? I have found so far that for every new instance that you create that you need to have a different virtual server name. How can you utilize the same virtual name and have multi insances
servername$instance1
servername$instance2
and so on

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.
We have a SQL 2014 active passive cluster with 5 instances. When the cluster was installed one of the nodes was a virtual machine. As we started to have problems and this is not a Microsoft supported configuration we decided to replace the virtual node with a phyiscal one. On 3 of these 5 instances we configured static ports (1433 TCP) this was required for applications and firewall implementation.
Now with the physical node joined to the cluster we have issues with these three instances. Whenever one of these instances is moved to the passive node the server authentication is changed from mixed to windows only. I'm no SQL expert at all but to me it looks like the configuration of the instances are not replicated to the passive node? I found some similar problems on the net but these are mostly under sql 2008.
I have a need to add a second Sql instance to an existing cluster. However I read in this article http://www.sql-server-performance.com/articles/clustering/clustering_best_practices_p1.aspx
that this is not recommended. Does anyone know why this is or what problems I may encounter?
Its is running Sql 2005 on a 64 bit windows Server 2003.

Hi
I have a cluster with 4 sql server 2000 instances and would like to upgrade 2 of these to sql server 2005 - is there any document or list of things to ensure I do
Thanks
Hello all: looking for some general advice on proper approach. looking to move databases off of a clustered instance to a new (non-clustered) server.
Got several issues i'd like some advice on.
1. This is an OLTP instance that's been around for a while & it's pretty well encrusted with apps & processes that attach to it. Therefore it would be a very good thing if we didn't need to change the connection information in several hundred places after the move.
I've tested one approach to this that seems to work: moved the instance to a server which has the same name as the cluster resource associated with the clustered instance and an instance that has the same name as the clustered instance.
For example: cluster install is aiproddbproduction, moved it to a box called aiproddb with a named instance called "production". There's a bunch of tedious network stuff that has to be done to make this work (binding an IP address to the MAC address of the new box and some murky DHCP reservation fiddling), but after the network crew got done cursing me it did finally work.
Does this seem like a reasonable approach?
2. What's the best way to transfer security info to the new instance? I used the transfer Logins DTS widget but had some problems with it not being able to find some groups in AD.
3. what's the best way to transfer DTS packages?
4. is it necessary for the new instance to be at the same patch level as the old instance? the old clustered instance is still at SP3 and i threw the latest SP4 on the new location. good/bad/indifferent?
5. i was planning on taking a full backup & restoring it to the new machine. Is there a better way? Is the wizard for copying databases a good thing?
Those are these issues i'm aware of and have given some thought to. There are probably things about this i haven't considered and would appreciate some word on.
thanks,
Garth
We have 5 instances on our clients old machine with SQL 2005, now they want us to move on cluster environment with SQL 2012.
Once I have installed and configured SQL cluster with single instance, but how to install SQL Cluster environment for Multiple instances.
Should I install all the instances first and than have to configure cluster ?
OR
Is there any way that first I will install cluster and than we can add the instances ?
What I have- Sql server 2012 (Standard Ed) Cluster on Windows 2012 R2 with both instances running on the same node- just to save on License, i.e. technically it’s Act/Pas cluster.
What I am looking for- how to configure cluster (e.g. via quorum, etc) to force both instances failed together? Means if for some reason 1-st instance will fail to node 2 another instance should follow (otherwise it will be Act/Act cluster and 2-nd license is required).
If there is no standard way (cluster configuration I mean) to do it I should create some custom process to monitor where each instance is running.
My environment has a 4 node cluster , 2 in primary and 2 in sec dc. Storage is sperate for both.
Need to setup always on for 4 Instances there on the 2 nodes of the primary dc. Is there any restriction in setting up always on for multiple instances for a cluster.
I'm reading up on Always on and I am confused what is the difference between AlwaysOn Availability Groups and AlwaysOn Failover Cluster Instances.
View 3 Replies View RelatedIt is an active passive cluster which doesn’t allow any testing. All instances have to be failed over together, we aren’t allowed to just failover 1 even for testing purposes. Node 1 is the active node and we can failover to node 2 for 30 days free of charge but services have to then be failed back.
We need to run the cluster with node 1 as the primary node always and 2 just use for failover testing or for less than 30 day periods whilst performing cluster patch upgrades etc.
Now l am sure we could fail over 1 instances at a time for testing and diagnosing issues plus if add a new instance that's not production to get to the platform level as the rest of the instances this would avoid taking production down in the fail over process.
Hi All..
We are planning to build a cluster environment on MS SQL 2005. We want to install multiple named instances in a single database server and use cluster for that database server.
Is this option possible ? Any relevant documentation would be helpful
Thanks in advance

We are running with a 2 node windows cluster having three SQL instances on it.
OS: Windows server 2008R2 SP1
SQL : SQL server 2008R2 (10.50.6529)
Currently both nodes have 256 GB or memory and we are having multiple auto failover for resources. What will be the best practice for OS memory reservation (OS+tools) so that we can set SQL max memory settings accordingly?
Hi There
I have found no real documentation on this, so any links would be greatly appreciated.
We have an existing 2 node active active cluster.
A default and and named instance SS2005 Enterprise Edition are installed on the cluster.
Recently we acquired new hardware, 2 servers, which we added to the cluster so we now have a 4 node cluster.
The 2 new nodes have OS etc installed.
Now i have installed sql on a new multi node cluster, i have upgraded sql server in an existing cluster BUT i have never installed sql on an existing cluster for new nodes for multiple instances.
Now i presume you simply run the install on one of the new nodes, do this for a default instance, selecting both 2 new nodes to installl on. And do this again for the named instance.
But in the past I have never been promoted for which nodes to install sql on, it simply does all the nodes BUT i do not want this.
And how will the cluster know where the binary files are for each instance on the new nodes?
In a nutshell, how do i install sql server 2005 for 2 new nodes in an existing 4 node cluster for multiple instances ?
Thanx
When I am in Visual Studio 2005, and I try to add an SQL database, I get the following error "generating user instances in sql server is disabled. use sp_configure user instances enabled to generate user instances." I am currently using SQL server 2005 Express. What do I need to do, to create an SQL database? Thanks in advance.
View 4 Replies View RelatedI had a server with SQL Server 7.0
I installed a named instance of SQL Server 2000 and then i passed all my DB
of the 7.0 instance to the 2000 instance.
Then i removed the 7.0 instance, that was the default instance.
So at the moment there is only the 2000 version, but it isn't the default
instance
Can the 2000 instance become the default instance? (So that clients can
connect to it simply through computer name, and not creating an alias)
thanks

Hi
We are planning to upgrade the SQL Server in our production environment from SQL Server 2000 to SQL Server 2005. This is a 4 Node cluster environment with 3 Databases on 3 Virtual instances. The main requirement is to achieve this with no/minimal downtime.
Could you please suggest or direct me to any documentation for the best practices used to upgrade such an environment?
Thanks

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

We're upgrading a SQL Server 2000 cluster (Active/Passive) running on Windows 2000 Server to a SQL Server 2005 Cluster running on Windows Server 2003. We can't purchase new hardware and we have no spare hardware. We also need to move from Windows 2000 Server to Windows 2003 Server at the same time. We want to keep downtime to a bare minimum.
What we were thinking was the following steps... Anyone try this?
1. Break the link between the servers.
2. Install a fresh copy of windows 2003 server on one side along with SQL Server 2005. While this step is running, the active node would still be live on Windows 2000 Server and SQL Server 2000 serving our customers.
3. Restore a copy of a backup from the active production side to the node we're upgrading and at that point we would bring the active node down, switching the active node to be the newly upgraded server.
4. As a final step, the old active node would now have the link to it broken, we would install a fresh copy of windows 2003 server on it and sql server 2005. At this point we would bring it back into the cluster and the cluster would be complete again.
Thoughts?

View 5 Replies View Relatedwith sql server 2000, it is possible to have multiple instances on one server. Now I want to make the second server a subscriber for specific tables before there are some tests/major changes. Has anyone experience with this on the same server. Note : sql server subscriptions between different servers in sql server 7 is not the issue.
View 1 Replies View RelatedI created a named instance of SQL Server 2000 on my notebook. I inadvertantly set the trusted SQL connection to Windows Authentication. This is creating a problem with COM because of username and password. I want to reset it to use SQL Server authentication but I can't find where to do it. Can I do this or do I have to delete this instance and create a new one.

Dear SQL Guru,I just found out this morning that my SQL Server box had been added 1more instance. Below is the example:PPAPP0075FINANCE (Old instance)PPAPP0075ACCOUNTING (Old instance)PPAPP0075Accounting (new instance)This is a case sensitive MS Sql server (third party vendor App). TheACCOUNTING instance is the one we have been using for our currentapplications. I found out the new one(Accounting) when I scan thenetwork by using OSQL -L utility. However, when NT engineers tried toverify the physical files location ofAccounting, and it did not exist. When I tried to register it and itdoes not appear from Enterprise Manager.Please keep in mind NT Engineers have been monkey around on this serverquite a lot in last a few weeks, especially modifying Registry keys.My question is, where did PPAPP0075Acounting come from? We never evertried to install any more instance on this server.Please help,Thanks,Silaphet,
