SQL 2012 :: MSDTC In Multi-node / Multi-instanced Cluster

Aug 17, 2015

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?

SQL 2012 :: Two Node WSFC On A Multi Subnet

Feb 10, 2015

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.

SQL 2012 :: Disaster Recovery Options For Multi-Database Multi-Instance Environment

Sep 23, 2014

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.

SQL 2012 :: AlwaysON Multi Subnet Cluster / AG Listener

May 3, 2013

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.

SQL 2012 :: Multi-Site AlwaysOn Failover Cluster

Oct 6, 2014

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 –


•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.

SQL 2012 :: Running 2 Distinct AGs On Each Node Of A Two Node Cluster?

Oct 23, 2014

I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.

SQL 2012 :: 3 Node Cluster Runs With 2 Node Failures?

Jun 11, 2015

We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).

As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.

However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.

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

SQL 2012 :: Cluster With Multiple Instances On The Same Node?

Jul 14, 2015

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.

SQL 2012 :: Two Node Active / Passive Cluster Installation

May 3, 2015

Few questions on a SQL Server 2012 two node active/passive cluster installation on Win2012.

1. What are the permissions required for the user used to install SQL Server 2012 cluster. Does it need to have any rights on DC or anywhere else apart from the local nodes ?

2. Can we give ANY meaningful name to "SQL Server Network Name" during installation ? Do we need to manually configure it anywhere else before or after the installation ?

3. On what scenarios we need to check/uncheck DHCP check box ?

SQL 2012 :: Node Cluster Active / Passive With 10 Instances

Jun 5, 2015

It 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.

Multi-database Multi-server

Mar 27, 2007

I am new to Reporting Services and hope that what I am looking to do is within capabilities :-)

I have many identical schema databases residing on a number of data servers. These support individual clients accessing them via a web interface. What I need to be able to do is run reports across all of the databases. So the layout is:

Dataserver A

Database A1

Database A2

Database A3

Dataserver B

Database B1

Database B2

Dataserver C

Database C1

Database C2

Database C3

I would like to run a report that pulls table data from A1, A2, A3, B1, B2, C1, C2, C3

Now the actual number of servers is 7 and the number of databases is close to 1000. All servers are running SQL2005.

Is this something that Reporting Services is able to handle or do I need to look at some other solution?

SQL 2012 :: Instance Name Not Appearing In Drop Down List On Cluster Node Configuration Window

May 29, 2013

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.

SQL Server Admin 2014 :: Making Single Subnet Cluster Multi-subnet

Aug 18, 2015

We 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}


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?

SQL Server 2012 :: How To Update Master Count Column From Multi Thread Application

Sep 28, 2015

We have an application that runs Jobs, each of which affect ## number of child objects (usually around 1M). When a thread gets to 5000 updated child objects it bulk inserts into a table called ActionLog with the child Id and JobId.

When the job is complete a sproc SUMs the children from the ActionLog table:
select sum(id) from ACTIONLOG where JOBID = @JobId;

It then updates the Jobs table AffectedObjectCount column with the sum(*) from above.

Instead of writing to the ActionLog table and calculating the SUM at the end I would like to do this 'real time'. After the bulk insert I would like to update the AffectedObjectCount column with the number of rows that were just bulk inserted. I tried this in the past and ran into major contention issues. There are usually 20 threads running a job so there exists a lot of potential for deadlocks.

Is there a recommended way to handle updating one column on one row from multiple threads? What is the best practice for a counter like this?
