Cluster: Instance Naming
Sep 3, 2007
Hi all
SQL Server 2005 cluster. Active-Active. We want to create two instances. The two nodes are named:
mike-940-01
mike-940-02
I read somewhere that there can only be ONE default instance in a 2005 cluster. So I interpret that as meaning that I can only have one instance named after a virtual server (example: mike-940-03) and the other instance has to be a slashed instance (example: mike-940-03/instance1). But what if I create another virtual server (example: mike-940-04). Can I install a default instance in that server? Can someone help me clarify this?
Also, if I'm using all slashed instance names, then what does it choose as the base name before the slash? In other words, what decides which virtual server name is used? Is it the management node? Is it one of the nodes?
My objective is to keep consistency in the naming on the cluster. If I have to use slashed instances, then I want all sql server instances to have a slash.
Sorry about the confusing explanation, but that's probably a symptom of MY confusion.
Thanks!

Hello,
I install Cluster naming instance of MSSQL 2005 Enterprise edition with SP2 and latest patch.
When I try connecting this instance from outside of the server by "server nameinstance name" I got connection error.
But when I connecting by "server name,port number" it's connecting with no problem.
Can someone help me resolve connection outside of the server with "server nameinstance name"?
Thanks

When I try to Add New Item - Database in VS C# Express, I get "An error has occurred while establishing a conncection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)"
When I open the management studio, I can connect to a database named Dev, and when I try to "Browse for more" from the server selector combobox, it is the only one found. I believe "Dev" was my old MSDE name, although this is also what my "Computer Name" is set to. Unfortunetly the setup of SQL Express didn't ask me what to name my instance.
I thought maybe the SQL Server 2005 Express Toolkit installation didn't actually contain the server software, and only installed the tools, as during the installation the section where I select components only listed things like client tools and what not, with not mention of the server software.
So I thought maybe it didn't install the server, so I downloaded the server installation that is by itself, and installed it, this time I saw the check for hide advanced options, so I went through the advanced options this time. I've have been through this same setup before at work, and both times it has confused me. It seems very different from installing previous versions of SQL server.
Where I choose to create a new instance or upgrade, I choose to upgade, and it is not clear what I'm upgrading, the selector does not display instance names.
At another point it asks me about configuring it to use the Local service, local system, or network account. The documentation of how these differ is vauge. For example, the network account is described basically as "don't use this" without saying what it is.
I was accustomed to just a local account, and network account settings from previous versions, and network was always the logical choice for me to use intergrated security. I don't understand what the new catagories represent and what will be functionally different in the way I connect.
So I'm really confused, and getting back to the instance names. In the surface area configuration as well as the VS Express, it only sees the name as MSSQLSERVER
For example if I "add new connection" from database explorer and click advanced, the datasource drop down lists only ".MSSQLSERVER"
So I'm thoroughly confused at this point and not sure what to do.

I ran the Advanced cluster preparation for a new sql instance on an existing cluster.
Slq Server 2012.
After is completed, it was successful, I realized I specified the wrong Instance Root directory.
Is it possible to remove what the preparation installed? Or is it possible to change the root directory?

I'm new to SQL Server and just installed VS 2005 and SQL Server 2005 Express. My question is, is there any naming rules for an instance? When I open Express Manager it is asking me to enter an Instance name. Thanks for any suggestions or help,

Hi There
If i have a 2 node cluster running a single instance (default) and i want to add another instance to the cluster , can i install the second instance as a defualt instance ?
Since the cluster instances are referred to their virtual names/ip's and if i choose to intall the binaries of the second instance to a different location is this possible?
Since in theory you never have 2 default instances running on a single server but each within a virtual server?
Normally i install a named instance but do i have to ?
Thanx

We have an active/active two-node QA cluster with four instances of sql. I need to add a fifth. In the past I always moved existing instances to the other node while installing a new instance.
Other than impacts to users from install reboots, is that a hard requirement?
QA is reluctant to have me put the four existing instances on one node for most of a day, fearing big performance slowdowns. Each node has 250GB of memory and each instance is allowed 50GB. Netapp disk backend.

I have a SQL 2008 R2 2 node cluster. For DR testing, I need to restore an instance on a new server (completely isolated). The existing instance runs on what I would call an alias. The actual cluster host name is SQLPROD (cluster nodes are SQL01 and SQL02). The instance runs on server SQLPROD-APPLE. The instance is called APPLE. In production, I use SQL Management Studio and I connect to SQLPROD-APPLEAPPLE.
I've setup a new VM to run SQL. Not a cluster. Host name is SQLREC. The new Vm has all the IP addresses that were on the cluster and the DNS for all the aliases are correct. I've installed instance APPLE. I created an alias called SQLPROD-APPLE. When I try to open SQL Management Studio and connect, I can't connect to SQLPROD-APPLEAPPLE. I can connect to localhostAPPLE, SQLRECAPPLE, 192.168.168.50APPLE.
When I attempt to connect to the alias I get error 18452. Pinging the alias resolves correctly. I haven't gotten to the database restore yet, so that's not a concern. I'm just trying to validate the connection first with the correct server and instance names.
I'm using Windows Authentication.

I understand most of the concepts for the Active/active setup. I am setting up a 2 node cluster. My question is can I use the default instance name (one default instance name per group) when setting up each instance or do I have to use named instances . I am assuming that since each group is a virtual machine that I can get away with using the default instance, but I cant find any documentation to confirm my frequently wrong perceptions.
I want to set it up like this
Instance1 Group
Group resources
Default SQL Instance Name Installation
Preferred Owner Node1
Instance2 Group
Group resources
Default SQL Instance Name Installation
Preferred Owner Node2
Thanks

Hi,
I am trying to remotely connect to a SQL 2005 Instance on a cluster. I see the following error:
No retry on exception System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I have enabled TCP/IP , Named Pipes on the node. I have turned off IPSec on the clients as well. I am using the following connection string : "Integrated Security=SSPI;server=servernameinstancename;Pooling=false;database=TrialDB"
Is there something I am missing?
Any pointers will be appreiciated.
thanks.

I have a system running a sql 2000 instance w/ multiple databases located in a SAN. I would like to cluster my SQL 2000 environment on the same system. Can I do this without reinstalling another database instance? Can I put my current default instance and put it to my virtual server instance? Help is really appreciated. Any tips and links can be helpful to me.

Having problems running the BPA for 2012. We setup using a clustered environment, SQL Server installed using default instance, and a static port not 1433. When I try to run the BPA using the instance name it says it doesn't exist, and won't let me add a port number. However, if I use MSSQLSERVER as the instance name it runs with no port specified and returns results. I assume that it doesn't require a port because the default instance would pull from the Browser Service and the using MSSQLSERVER is the same as running the default on a standalone server. Are those assumptions correct?

Hey,
I have a 3 node cluster running 6 instances of SQL Server, I want to install Analysis Services along side of one of the SQL 2005 instances. Thus one of the cluster instances would host SQL Server DB, Analysis Services and SQL Agent. Is this possible or does Analysis Services need it's own Cluster Instance.
Thanks!

I've a fresh installation of SQL Server 2014 Enterprise on Windows Server 2012R2. I've setup de Windows Server Failover Cluster and the validation test has been successfully passed. I use mountpoint so I've disk M: that is the host drive for mounted volume m:Isql2014A that is the base folder for mounted volume
On that folder I've 5 mountpoint:
1) m:isql2014a empdbdata
2) m:isql2014a empdblog
3) m:isql2014auserdata
4) m:isql2014auserlog
5) m:isql2014auserlog
into these 5 mountpoint I've placed the SQL Server files.
After the installation of the first FCI I've re-run the cluster validation wizard and again it has passed successfully. When I try to failover the instance from one node to the other I have 2 problem:
1) every time I do failover, some disks fail to come online for a while and then succeed :
Cluster resource 'CLD - IstA - TempDB Data' of type 'Physical Disk' in clustered role 'SQL Server (ISQL2014A)' failed. The error code was '0xaa' ('The requested resource is in use.').
2) sometimes the SQL Server service fails to start, in the error log I see that the master database is not accessible. The master database in into the m:isql2014abinbackup.

Is there a way for multiple SQL 2005 instances in a cluster to share drives for user databases.
Once we install our instances in the cluster using seperate disk resources. Can we then have multiple instances share the same physical disk for user databases only. This is for a test environment.

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.

We have a SQL 2008 Instance existing on active/passive cluster with 2 nodes running on Windows server 2008 R2 Ent. Edn.
Now we need to install another SQL instance on this cluster. So what are the prerequisites apart from new IP address? Do we need shared disks or can the existing disks can be utilized?

Hi all. I have ran into a annoying situatin on sql cluster. Config is:
w2k3 EE x64 r2 - two nodes
sql 2005 x64 standart v2153
2instances, active-active cluster.
While changing tcp port configuration of one instance (using configuration manager) I have acidentaly created that setting:
- All IP dynamic port and All IP port was set to same number while separate IPs have enabled dynamic ports and does not have static port set.
This situation leads to unability of starting the instance anymore. There is no need wide explanation, its quite clear - while starting instace, it was configured with static port and with dynamic port with the same number, so port conflict error takes place. Problem was how to escape from this situation. On non clustered sql is quite easy, because these settings are stored in registry and also can be changed thorough Configuration manager, easy solution. Nor on the cluster.. Modifying the registry even on both nodes was unefective, every try to start instance fails with port conflict error and bad config was saved to registry again. I wasnt able to find where this config resides and change it to corect values. I have revealed only that it is not stored in instance master DB (restoring it from backup). Looks like its held somehow by cluster service itself, but I didnt find where it should be and how to edit it. So the last possible option take place (time was against me) - reinstalation of whole clustered instance. Nice example of how one click can create you a 2 days of work... Iam still interested if there is a smooth and easy way out of this situatin:-) So if anyone knows..... If there is not, I realy warn everybody.

I am trying to install the MS SQL Server 2012 Failover Cluster on Windows Server 2012 . I successfully Installed the Failover cluster instance on my primary node.
But when I am running the installation process on passive node to add node in the failover cluster I am stuck with very unique kind of issue.
I am following the Standard process of Installation and I am getting the same windows for each next process, but after License Agreement window when I get the Cluster Node Configuration window, then in "SQL Server Instance Name" drop down box I am not getting the Name of Instance which is already installed on the primary node. But this Instance complete information is appearing in below given box.
Only issue is Instance name is not appearing in the drop down list, that's why I am not able to select and when I click on next it trough error and do not proceed.

During the installation of Adding node to a SQL Server failover cluster(On passive node) getting error like.. The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.We run the below commands but didn’t get any resolution & got the same above error .
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).
2. net stop winmgmt
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).
4. net start winmgmt
2<sup>nd</sup> Method..
1. Disable and stop the WMI service.
a) Command : - sc config winmgmt start= disabled
b. Command : - net stop winmgmt
2. Run the following commands.
a). Command: Winmgmt /salvagerepository %windir%System32wbem
b). Command: Winmgmt /resetrepository %windir%System32wbem
