SQL Server Admin 2014 :: Active Passive Cluster With 5 Instances
Nov 4, 2015
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.

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.

We have a SQL cluster server running with SQL 2005 Enterprise Edition SP2 on Windows 2003 Enterprise Edition.
Currently the cluster has 2 nodes with Active/Active. Now I need to add a new node as a Passive node. So after I have done it, the cluster will be a Active/Active/Passive cluster.
Because the cluster is a production server, I need to know exactly how I add a new node onto the current cluster without breaking anything. Also this is my first time to install a passive node, so it is difficult for me to understand how to install and configure it.
I have already added the physical node onto the cluster group so I can see the new node €˜paused€™ from the Cluster Administrator. Now I need to install the SQL but I am too nervous to run the installation program.
My questions are:
1. Do I need to run the SQL install program from one of other active nodes in order to install the SQL on to the new node? Or is it ok to run the SQL install program from CD?
2. Do I need to create a new virtual name, a new SQL named instance and a virtual IP address for the new passive node?
Physical node name Virtual name SQL Server Instance Name IP address
Node1 (active) SQL1 SQL1 xxx.xxx.xxx.100
Node2 (active) SQL2 SQL2SQL2 xxx.xxx.xxx.110
Node3 (passive) SQL3??? SQL3SQL3????????? xxx.xxx.xxx.120????
3. Is there a risk to delete or change the current active nodes? If so, will you let me know as I will be super-careful not to do it.
I highly appreciate your help!

Hi
I am having some teething problems while installing SQL on a 3 node cluster. Within the Cluster configuration I have 3 Cluster Groups with each of them having their associated disk resources. All these disk resources physically exist on a SAN.
The actual cluster is running absolutely fine and I can access all the disks from their respective owner node. The problem only starts when I start installing SQL Server 2005 on this cluster. I specify the Cluster group from the Cluster Group Selection and choose the desired partition and then the error message pops up
"There is not enough diskspace on the destination disk for the current SQL Server data files. To proceed, free up disk space to make room for data files, or install the data files to a different drive"
But the disk I am trying to install it on is 264Gb and none of it is used. I have also tried to change it to a different disk within the same Cluster group but to no avail. I have even tried to install it in a different cluster group all together but I get the same error message.
I have googled around havent found anything so far. The disks have got full permissions for the account I am installing SQL with.
Any help will be much appreciated.
Regards
Adnan

I have upgraded our test server and on non cluster production machine. My next server is a cluster and I don't have a test cluster server. Do I upgrade the active node and that is all or am I going to need to fail it over and upgrade the other node.
Also the prerequesite for the upgrade advisor is .net 2.0 I am going to up that on each server one at a time but I am only going to add the upgrade advisor to one node is that ok.
I read the SP1 documentation and it clearly states only patch the active node and do not patch the inactive nodes.

I have a 2 way cluster and I want to apply SP4 on it.
Basically, I have 2 servers. Server A runs a default instance and another instance. While the default services is disabled and the other instance is running, Server B runs the default instance and has the other instance disabled. This basically acts like a 2 way cluster (active/passive).
How can I apply SQL Server 2000 SP4 on the 2 servers and have all the nodes come up the correct way? What are the steps to achieve this?

I invoke xp_cmdshell proc from inside a stored procedure on a 2-node active/passive SQL 2005 SP2 Standard cluster. Depending on which server the xp_cmdshell gets executed on I need to pass different arguments in the shell command. I thought I could use host_name() function to get the runtime process server, however, I am finding that it's not behaving correctly. In one example I know my active node is server2, but the host_name() function is returning server1. The only thing that I could possible explain this is that the MSDTC cluster group is not always on the same active node as the SQL server group and in the case I am talking about the cluster groups are in this mode (differnet nodes). Does the xp_cmdshell get executed by the SQL active node or the MDTC active node? And what is the best way to find out which server is going to run my xp_cmdshell?
Thanks.
Edit:
Perhaps another by product of this is that if I run select host_name() from the Studio Management query window i get different results depending on which server I am running the Studio Management on. On server1 I get server1 and on server 2 I get server 2, all the while server2 is the active node. I need a different function that will always let me determine the correct server that'll be running the xp_cmdshell...
Edit 2: I guess I could determine the running host inside the command shell itself, but I am curious to see if i can do it (cleaner) from SQL.

I just tried to apply SQL 2005 Std SP2 on a cluster, and all succeeded except for the Database Services. I've looked about and can't see any specific information for this. The Summary.Txt is below. I thought I was following the appropriate steps, according to the SP2 Readme.
Thanks for any help. (I'm at the client today)

This is the 1st time we are building a active/passive cluster with 1 node each. we usually install default instance and setup domain account as service account which will have an spn delegated. Now for active/passive cluster is it ok to use same domain account as service account for both clusters with both creating as default instance again as the windows was built as SERVER1 and SERVER2.

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 ?

Hi all,
I have some doubt about the IP Required for configuring cluster(both Window and SQL server)
Details :
----------
How Many IP(Public & Private) Required for 2 Node Active/Passive both window and SQL server Cluster ?
IP(Public & Private) Required :
---------------------------------------
1 : For Window Clustering : 2 node Active/Passive Cluster ? How many ip ?
2 : For Sql Server Clustering : 2 node Active/Passive Cluster ?how many ip ?
3 : Is there any mathematics for that ? How to analyse the IP requirement ?
Thanks

Could someone give me an ideal of what it takes to upgrade the memory in my cluster. Is it as easy has upgrading the passive node, switching the nodes, then upgrading the other server. And do I need to re-configure the windows cluster. And will both server need to be down at the same time at any point.
Or is their more to the process? Thanks for any assistance.
btw, I currently have 16mb of RAM in each node.

Greetings,
I need to install the SSIS components on the referenced database server. I believe the SSIS components are cluster aware, so I was planning on just doing add/remove and selecting the components. Rather than breaking the cluster apart to patch the components back to SP1, I was thinking of just running the SP2 install right over the top of the running cluster to bring everything up to SP2.
I'm looking for any suggestions/comments on whether this is the proper way to proceed or if I'm going to have a problem.
TIA

I am tasked with correcting 600 SQL Server instances default settings. I would like to use powershell, if possible to loop thorough each named instances (I have a list) and apply the following settings. I also need to query the server for the installed memory and apply * 80% logic for maxmem, and look at the VCPU count and adjust the MAXDOP to that number.
USE MASTER

EXEC sp_configure 'recovery interval (min)', '0';

EXEC sp_configure 'allow updates', '0';

we have roughly 22 people connected to one database. But after a while, their applications begin to drag due to in and out communication with the server. When i check the active connections on the sql server, some times i see 157 active connections, please how to i set a timeout or connection interval close, so as reduce the heavy load being put on the server. Or how can i automatically close connections when they get higher than 50 connections.
This settings should be sql server 2008 related.

I am running into a weird issue with a new SQL Reporting Services 2014 server I built. I installed SQL Reporting 2014 on Windows Server 2012 R2 and configured Kerberos, but the site is extremely slow. After some reconfiguration and log captures I have determined the issue has to do with the Kerberos setup, however I am running a similar configuration with SQL Reporting Services 2008 on Windows Server 2008 R2 and do not run into the same errors.
The error I see while using Wireshark is KRB Error: KRB5KDC_ERR_BADOPTION NT Status: STATUS_NO_MATCH. When I drill down the into the error I can see the kerberos string is testprjmnmtreports14.company.com, which is the URL we are using to access the site. I made sure to add that name as an SPN for the service account that is running SQL Reporting Services, however I still receive the error.
Then I tried configuring the site to run without a hostheader, so I accessed the site with the server name, ECTSTSQLRS5, and the site works perfectly fine, no errors are reported either. So it seems I have isolated the issue down to Kerberos but I am not sure how to resolve it. Here is some more information about my environment:
DNS/URL used: testprjmnmtreports14.company.com
Server Name (FQDN): ECTSTSQLRS5.company.int
AD Domain Name: company.int
Server Version: Windows Server 2012 R2
AD Functional Level: 2008 R2
As you can see I am trying to use a .com address but my AD domain is .int which I think is the issue, but I do not have the same problem on my other server that is running Windows Server 2008 R2. What do I need to do to allow my new site on 2012 R2 to work with this DNS Alias?

I want two write a small script to determine which is the currently active (primary) server in the AG.
Right now, I see that using SELECT * FROM SYS.dm_hadr_availability_replica_states I can determine the role. However, when the server goes down and switches to the secondary node, I don't believe that the role changes (or does it?). How do I determine which is the active node?

I am playing around in a test environment with SQL Server 2014. I have a question about the default location of the report server databases when you have multiple report server instances installed on one server.
I did a very simple install of SQL Server 2014 with the database and Reporting Services in Native Mode (install only) features selected. Accepting the default locations, I ended up with the following locations as you would expect:
C:Program FilesMicrosoft SQL ServerMSSQL12.MSSQLSERVER
C:Program FilesMicrosoft SQL ServerMSRS12.MSSQLSERVER
Running the Reporting Services Configuration Manager, I created the Report Server database. After creating the Report Server database, the related files will be located below in the SQL folder as I would expect.
C:Program FilesMicrosoft SQL ServerMSSQL12.MSSQLSERVERMSSQLDATA
Next I installed another instance, which I called Test, of SQL Server 2014 like I did above. I now have the following folder structure the Test instance as I expect.
C:Program FilesMicrosoft SQL ServerMSSQL12.TEST
C:Program FilesMicrosoft SQL ServerMSRS12.TEST
Running the Reporting Services Configuration Manager, I select the Test instance and create the Report Server Test instance database.
My first thought would be that the Test instance Report Server database would be in the following location:
C:Program FilesMicrosoft SQL ServerMSSQL12.TESTMSSQLDATA
Instead this database is located with the default instance Report Server database:
C:Program FilesMicrosoft SQL ServerMSSQL12.MSSQLSERVERMSSQLDATA

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.

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.

We 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!)

Due 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.

I 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.
