SQL Server Admin 2014 :: Design AlwaysOn Cluster
May 8, 2015I got 5 SQL Servers 2008R2 (2x CPUs with 96-384Gb of RAM) with total 1500DBs and around 10Tb of allocated data. Now
I am forced to upgrade to 2012 and 2014, but the old hardware is overkill.
Is it possible to consolidate this to a large SQL AlwaysOn cluster?
We pros/cons could it be to have 2 or 4 nodes?
2 or 4 sockets servers?
My goal was to use ~20 cores Enterprise license on active server.
SQL Server Admin 2014 :: Deadlock Because Of Non-Cluster Index
Jun 11, 2015Dead lock is coming in select query in application because of index. It is identified after enabling trace in database and identified by reading deadlock xml file. After index removal, deadlock is not coming in same query. But it is affecting query's performance slightly. Is it correct way to remove index if dead lock is coming because of index?

Jul 21, 2015I have installed 2 node windows Fail-over clusters successfully. But QUARUM Configuration is not appearing in Failover cluster manager instead "Witness: Disk (Disk Cluster 4)". I have also configured quarum configuration from Quarum "Configure Cluster QUARUM Settings". I have attached the snapshots of windows cluster configuration. Is it the issue or not. I have not got any warning and error during cluster validation while installing Windows failover cluster. I am assuming it is okay and i can move ahead to installation of SQL Failover cluster setup.
Products used for installation in Virtual Machine:
Windows Server 2012 R2
SQL Server 2012 R2

SQL Server Admin 2014 :: AlwaysOn Secondary Down -> Whole Cluster Goes Down
Oct 25, 2015We had a big issue today during maintenance work in our SQL environment.
So our environment:
- 2x SQL Server 2014 Enterprise on Windows Server 2012 R2 (SRV1 and SRV2)
-- Both Hyper-V VMs on different Hosts
-- Both configured to an Windows Failover Cluster and AlwaysOn Availability Group (AG1)
-- AG Listener: AG1_lis
-- No shared storage (each Hyper-V Host has its own local storage)
-- Asynchronous Mode
-- SRV1 is primary, SRV2 is secondary SQL node
What happened?
- Shutting down Windows on SRV2 due hardware maintenance
- Cluster goes offline, AG1 goes offline
-- Error message: "Stopped listening on virtual network name 'AG1_lis'."
-- Error message: "The availability group database "DatabaseXY" is changing roles from "PRIMARY" to "RESOLVING" because the mirroring session or availability group failed over due to role synchronization."
Results?
- AG1_lis wasn't available for our applications and they stopped working properly because database connection was lost!
I think, I HOPE, this is not the normale behaviour when one node is shutting down (especially the secondary node!)

SQL Server Admin 2014 :: Active Passive Cluster With 5 Instances
Nov 4, 2015We 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.
SQL Server Admin 2014 :: Using Machine Name Already Exists Error After Cluster Installation Failure
Sep 10, 2015Due to a SQL 2014 cluster installation failure related to security while setting up the primary node, I had to remove the node and any related installation programs from the node and redo the installation again. However I am unable to use the machine name as the SQL network name during the instance configuration, I get the following:
Microsoft.SqlServer.Chainer.Infrastructure.InputSettingValidationException: The SQL Server failover cluster instance name "MachineName" already exists as a server on the network. Specify a different failover cluster instance name.I am still getting the same name since the node name "MachineName" is listed under the cluster name. I have used machine name as SQL network name without an issue. I do not have any existing SQL machine name in network using same machinename which I want to use for this installation.
SQL Server Admin 2014 :: CLUSDB Files Missing - Cluster Service Not Coming Up
Oct 9, 2015I have configured windows failover clustering 2012 on 4 of my test nodes.
I am trying to add another node into this cluster but its not happening. I am not even able to start the cluster service in services.msc
After installing windows failover clustering, when I go to the C:WindowsCluster folder, I am unable to find CLUSDB, CLUSDB.1.container, CLUSDB.2.container and CLUSDB.blf files in the folder.
These files are very much present on the other nodes where cluster service is running.
I tried copying these files manually to server where its missing but still no luck.

Aug 18, 2015We 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?

SQL Server Admin 2014 :: Server Min And Max Memory On Cluster
Oct 9, 2015I have the following SQL FCI configuration:
NODE1 -256GB
INST1 - 64GB min/64GB max
INST2 - 64GB min/64GB max
NODE2 - 256GB
INST3- 64GB min/64GB max
INST4- 64GB min/64GB max
With this configuration and if all instances are running on the same node there will be enough memory for them to run. Knowing that normally i ll have only 2 instances in each node wouldnt it be better the following config?
NODE1 -256GB
INST1 - 64GB min/128GB max
INST2 - 64GB min/128GB max
NODE2 - 256GB
INST3- 64GB min/128GB max
INST4- 64GB min/128GB max
With this configuration and in case all the instances (due to a failure) start running on only 1 node, SQL will adjust all instances to just use Min memory specified?
SQL Server Admin 2014 :: Does Security-admin Role Plus Deny Alter Any Login Cancel Each Other Out
Aug 27, 2015I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.
I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.
I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).
So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.

Active/Active Cluster Failure - How Do You Rebuild And Rejoin A Node In The Cluster?
Aug 30, 2006We have (had) an active/active cluster. 2 physical machines,
each running their own instance, clustered together. Node1/Ins1 and Node2/Ins2.
Node2 failed and Ins2 failed over to Node1 as it should. Node2 required that we
rebuild the server (rebuild = reinstall O/S). Now we need to get Node2 back
into the cluster and get Ins2 failed back over to Node2.
Does anyone know, for certain, the correct steps to accomplish this? Obviously,
we could backup everything and completely destroy Ins2 and recreate it on Node2
then rejoin the cluster. But I'm looking for something less destructive.
Is it possible to reinstall SQL, then rejoin the cluster, and then fail Node2
over? Or will there be registry conflictions?
Any help would be appreciated. Also, if you have any links to some official
documentation, that would be great too.
Thanks
Upgrading A SQL Server 2000 Cluster To A SQL Server 2005 Cluster
Dec 28, 2007
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?
