SQL 2005 Multi-Instance Cluster Question
Mar 19, 2008
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

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

More often than not, I typically don't touch DTC on clusters anymore; however on a project where the vendor states that it's required. So a couple things here.
1) Do you really need DTC per instance or one for all?
2) Should DTC be in its own resource group or within the instance's group?
2a) If in it's own resource group, how do you tie an instance to an outside resource group? tmMappingSet right?

Disaster Recovery Options based on the following criteria.
--Currently running SQL 2012 standard edition
--We have 18000 databases (same schema across databases)- majority of databases are less than 2gb-- across 64 instances approximately
--Recovery needs to happen within 1 hour (Not sure that this is realistic
-- We are building a new data center and building dr from the ground up.
What I have looked into is:
1. Transactional Replication: Too Much Data Not viable
2. AlwaysOn Availability Groups (Need enterprise) Again too many databases and would have to upgrade all instances
3. Log Shipping is a viable option and the only one I can come up with that would work right now. Might be a management nightmare but with this many databases probably all options with be a nightmare.

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 have figured out that SSIS installs once for as many instances of SQL Server 2005 as there are on the machine. I also figured out that even if there is only a named instance on the machine, it will always install under the "Default" machine named instance.
I also figured out that you can change the instance viewed by modifying C:Program FilesMicrosoft SQL Server90DTSBinnMsDtsSrvr.ini.xml
What I am unclear about is that in SQL Server 2000, each Instance had an MSDB db which stored all of the jobs. In SQL Server 2005, each instance still has an MSDB DB but theSSIS also has a MSDB DB ?? or is this pointing to the MSDB for the instance specified in the xml file???
There is not much info out on this at all and would be good if the MSDB help explained this install once so it would all be clear!
THanks for any help... thank goodness for newsgroups!

If I have a job that runs every minute, and that job happens to take more than one minute to run on occassion, will SQL Server start a second instance of the job or will it be serial - one after another ?
Thanks,

When I fail an availability group between subnets, I am finding that the DNS entry in DNS is staying. So what happens is the Availablity Group listener has 2 records in DNS, one for each IP. This causes the App to timeout at times, since DNS will return either of the two IP's.

We are implementing a multi-site (Windows Server Failover Cluster) WSFC to enable Always On between our primary and DR site. We are not going to use SQL clustered instances. We are not planning to use shared disks. Each node is running a standalone instance of SQL 2012.
I have successfully configured a 3 node multi-site Windows failover cluster with no shared storage. For quorum, I have defined a File Share Witness (FSW). The FSW has voting rights and is in the DR site. The setup looks like this –
WSFC –
•Node A – Site #1 (voting right = 1)
•Node B – Site #1 (voting right = 1)
•Node C – Site #2 (voting right = 0)
•FSW – Site #2 (voting right = 1)
Again - There are no shared disks in our setup. We are not going to use SQL clustered instance. We are going to use Always On with these 3 nodes.
SQL Always On –
•Node A – Site #1 (Primary Replica)
•Node B – Site #1 (Readable Secondary)
•Node C – Site #2 (Readable Secondary)
All the setup including the “availability group” works properly under this setup. However, a failover to site #2 under DR situation is not working and I know why but don’t know what needs to be done to fix the problem.
The following works fine –
•Automatic failover between nodes A and B (same site – site #1)
•Forced failover to node C in site #2 provided at least one of the nodes in site #1 is up (non – DR situation) - this will ensure the cluster is up
The following is not working –
•Forced failover to node C in site #3 when both nodes in site #1 are lost (true DR situation) – This is because the cluster is not up at this point.
I know I have to bring the cluster up somehow and I have not been able to do so by restarting the cluster service.
I tried to run the command to start cluster service.
Question –
How can I FORCE the cluster to come up in Site #2 on node C when it has no voting rights?
I have always worked with even number of nodes and shared disks with traditional clustering. I am not sure what needs to be done in this scenario with 3 nodes and a FSW.

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!

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 went as far as giving the folder full access to everyone temporarily and received the same error.

I have 2 SQL server installs for 2008 R2 configured as multi instances. I have a product called Esri ArcMap 10.3 that can be used to generate a database. When I run the wizard against one installation, the wizard successfully creates the database. When I then run the same against the other installation it fails with the following error [Microsoft][SQL Server Native Client 10.0]Invalid cursor state
I've attempted to look at the configuration of each using
select *
from master.sys.configurations
From this I found several differences
Successful Mulit instance
Optimize for Ad hoc Workloads – False
Max Degree of Parallelism - 0
UnSuccessful Multi instance
Optimize for Ad hoc Workloads – True
Max Degree of Parallelism - 4
I attempted to co-ordinate the differences running the wizard for each iteration but it always failed with the same error above. The error always seems to occur when a particular store procedure is run. There are quite a number of scripts run prior to this and are technically under the covers and only discovered via tracing, in this case using SQL Profiler. I don't have access to individual scripts that I can run incrementally to replicate the issue. I have to rely only on the Esri Wizard.
Reviewing the error against several forums suggests that this is an ODBC error but the trace I ran using SQL Profiler finds that the driver used is Native.
My question then is "What are the conditions that would cause this error above (Invalid Cursor)?" "Is there other configuration settings that are not captured via the SQL identified above?" "Could this be caused by mapped drives for data, Logs and Temp?"

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.

Hi,
I've went throught the SP4 documentation but I didn't find a clear answer about how to deal with this situation:
In the situation of a multi instances server in which all instances are SP3a, can I just upgrade a couple of instances to SP4 and leave the others in SP3a ? .
One of the instances I may have to leave in SP3a belongs to a merge replication environnement (Distributor and Publisher), while the Subscriber is also in SP3 on a remote server (which I don't administer..).(the point is that in this situation I have to upgrade the 2 servers simultaneously)
In other words, when I 'll apply the SP4 to just one instance, I understood that the all the tools will be upgraded to SP4.
Will the merge replication involving a SP3 instance on the same server still work?
Thanks for your comments/replies/ideas.
Regards,
jalal

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.
