Exploring AlwaysOn Failover Cluster Instances in SQL Server 2014 Tecnet Labs

I like the Labs and have found them very usful. I have a problem with: Exploring AlwaysOn Failover Cluster Instances in SQL Server 2014. The lab starts but hangs on opening SQLONE and the Manual never loads. I have tried coming out and starting again but
get returned to the same failing session. I thought I would mention it here as the is no way to feedback a response as the appraisal only happens once the lab is completed, i.e. no apparent link on the lab site. The session ends when the HOL is reported
as not responding.

Cannot uninstall instance of SQL Server 2014

Hello,
I have two instances of SQL Server 2014 installed and i want to uninstall them (and install SQL Server 2012 evaluation). I managed to uninstall the one instance. When i try to uninstall the second a message informs me that the operating system does not meet
the minimum requirements. I had the same proble when uninstalling SQL Server 2012 and i went to the setup file and changed the compatibility mode to Windows Vista. Is there something similar that i should do in the case of SQL Server 2014 or i should do something
totally different?
Thanks in advance,
Andreas

Hi,
Personally I have not faced this situation but this seems bug below Connect Item MS closed as not reproducable
https://connect.microsoft.com/SQLServer/feedback/details/707706/unable-to-uninstall-sql-server-2012-rc0-from-control-panel
Below connect Item deals with same issue as your
https://connect.microsoft.com/SQLServer/feedback/details/974626/cannot-uninstall-sql-express-2014-on-windows-7-sp1
Workaround should be instaed of uninstalling using GUI please use command prompt
Launch setup.exe from an elevated command shell. Change to the directory "c:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\SQLServer2014", then type:
Setup.exe /action=uninstall
Please change uninstall script as per need
Normal uninstall Script would look like
Setup.exe /Action=Uninstall /FEATURES=SQL,AS,RS,IS,Tools /INSTANCENAME=InstanceName

How to restore a database backup taken from a SQL Server 2012 instance to SQL Server 2014

I am trying to restore a database backup taken from a SQL Server 2012 instance to my new SQL Server 2014 instance. When I add the .bak through the Mgmt studio UI, it does not seem to find a backup set in the file so I cannot proceed (does not give
me any errors though either. I tried restoring through TSQL command but only got a database restore terminating abnormally error with no other details. How can I restore this database to SQL 2014?

Transactional replication from a failover cluster instance to a SQL Server Express DB

Hello,
I have been poking around on Google trying to understand if there are any gotchas in configuring transactional replication on a instance DB of a failover cluster, to a SQL Server Express DB. Also, this client would like to replicate a set of tables between
two instances DB's which both reside on nodes of the cluster.
Everything I've read suggests there is no problem using transactional replication on clustered instance as long as you use a shared snapshot folder. I still have some concerns:
1) Should the distributor need to live on a separate instance?
2) What happens in the event of an automatic, or manual failover of a publisher, especially if the distributor does not need to live on a separate instance? I know that when a failover occurs, all jobs in progress are stopped and this seems like a recipe for
inconsistency between the publisher and subscriber.
There is a paramount concern, that this particular client won't have staff on hand to troubleshoot replication if there are problems, hence my hesitancy to implement a solution that relies on it.
Thanks in advance.

1) Should the distributor need to live on a separate instance?
Answer: It is recommended to configure the distributor on the different server, but it also be configured on Publisher/subscriber server. (Subscriber in our case is not possible as its a Express edition)
2) What happens in the event of an automatic, or manual failover of a publisher, especially if the distributor does not need to live on a separate instance? I know that when a failover occurs, all jobs in progress are stopped and this seems like a recipe for
inconsistency between the publisher and subscriber. There is a paramount concern, that this particular client won't have staff on hand to troubleshoot replication if there are problems, hence my hesitancy to implement a solution that relies on it.
Answer: If you configure both publisher and distributor on the same server and the SQL instance is failed over, the data synchronization/replication is suspended till the instance comes online.
Once the instance is up,all the replication jobs will start again and it will continue to synchronize the data to subscriber. No manual intervention is required.

SQL Server 2014 Expired-Not allow the licensed Standard Edition SSMS

Hi
I have installed SQL server 2014 Enterprise edition Trial version, It is expired, So i install the SQL server 2014 standard edition , now if i type ssms in my server,It show , Evaluation period has expired, guide me how to change the ssms instance
to my sql server standard edition
Thanks & Regards Manoj

Manoj - For upgrading the evaluation edition , the only upgrade option will be to upgrade it to Enterprise Edition. There is no downgrade path for it.
Having said this, you can either upgrade to ENT edition or follow these steps:
Take backup of User Databases
Un-install/Remove the existing instance
Install SQL Server 2014 Standard edition and restore your databases over it
Few important considerations:
You can restore user databases to standard edition provided you are not using any enterprise class features such
       Database Partitioning
       Data Compression
       Change Data Capture
       Transparent Data Encryption
To know whether any of the above are enabled use this query:
SELECT * FROM sys.dm_db_persisted_sku_features

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

Perform Forced Manual Failover of Availability Group (SQL Server 2012) and WSFC (Windows Server Failover Cluster)

I have a scenario with the three nodes with server 2012 standard, each running an instance of SQL Server 2012 enterprise, participate in a
single Windows Server Fail-over Cluster (WSFC) that spans two data centers.
If the nodes in the primary data center are unavailable due to data center outage. Then how I can able to access node in the WSFC (Windows Server Fail-over Cluster) in the secondary disaster recovery data center automatically with some script.
I want to write script that can be able to check primary data center by pinging some IP after every 5 or 10 minutes.
If that IP is unable to respond then script can be able to Perform Forced Manual Fail-over of Availability Group (SQL Server) and WSFC (Windows Server Fail-over Cluster)
Can you please guide me for script writing for automatic fail-over in case of primary data-center outage?

+1 to David's comment. I would not suggest to run a script automatically. During such failover you might have data loss and decision has to be made with business owners during disaster.
During such situation, you need to start cluster service in force quorum mode (/fq switch) and then perform manual failover of AG to DR site.

You are trying to implement manually what should be happening automatically in the cluster. If the primary SQL Server becomes unavailable in the data center, it should fail over to the secondary SQL Server automatically. Is that not working?
You also might want to run this configuration by some SQL experts. I am not a SQL expert, but if you have both hosts in the data center in a cluster, there is no need for replication between those two nodes as they would be accessing
the database from some form of shared storage. Then it looks like you are trying to implement Always On to the DR site. I'm not sure you can mix both types of failover in a single configuration.
FYI, it would make more sense to establish a file share witness in your DR site instead of placing a third node in the data center for Node Majority quorum.

Upgrading from SQL Server 2012 Standard to SQL Server 2014 Standard Failover Cluster

Goal: To upgrade my default instance from SQL Server 2012 to SQL Server 2014 in a failover cluster.
Given:
1) Operating System Windows 2012 R2
2) 2 Virtual Machines in a cluster with SQL Server as a Guest Cluster resource. The two VMS are called APPS08 and APPS09. They are our development environment that is setup similar to our production environment.
Problem: When running the SQL Server 2014 upgrade, I started on the VM that was not running the instance. I then moved onto upgrading on the node that was running the instance. As soon as the install attempt to failover the running instance
an install error occurred that it could not failover. After many install attempts I consistently received the error
The SQL Server Failover cluster instance name 'Dev01'
already exists as a cluster resource. Opening Failover cluster manager there is no record of a DEV01.
New Strategy: Create a SQLCluster called DEV07. At the end of the Install I get 'Resource for instance 'MSSQLSERVER' should not exists. Neither I nor my Windows 2012 guy understand what Resource the install may be referring to.
We do not see anything out of the ordinary.
Any suggestions as to what Resource may be seeing the default instance would be greatly appreciated.

Hi PSCSQLDBA,
As your description, you want to upgrade the default instance in SQL Server cluster.
>> 'SQL Server failover cluster instance name 'Dev01' already exists as cluster resource'
This error could occur when there is a previously used instance name which may not be removed completely.
To work around the issue, please use one of the ways below.
1. At command prompt, type Cluster res. This command will list you all the resources including orphan resources. To delete the orphan resource, type Cluster res <resource name>/delete.
For more information about the process, please refer to the article:
http://gemanjyothisqlserver.blogspot.in/2012/12/sql-2008r22012-cluster-installation.html
2. Delete DNS entries, and force a replication of DNS to the other DNS servers.
For more information about the process, please refer to the article:
http://jon.netdork.net/2011/06/07/failed-cluster-install-and-name-already-exists/#solution
>> 'Resource for instance 'MSSQLSERVER' should not exist'
This error could occur when you already have MSSQLSERVER as a resource in the cluster, which may not be removed completely. To work around the issue, you could rebuild the SQL Server cluster node.

Dedicated network for AlwaysON replication traffic when a replica is a Failover Cluster Instance

Hi,
We are planning to setup dedicated network for our Availability Group replication traffic. We have a Failover Cluster Instance as the primary replica and a standalone SQL server instance as the secondary.
I understand that we will need to manually configure the database mirroring endpoints on both the replicas to listen on the specific IP.
But how do I configure the database mirroring endpoint on the Failover Cluster Instance ?
Please help.
Thanks and Regards,
Jisha

If you have a dedicated network for your Availability Group replication traffic between the FCI and the standalone instance, you need to identify if there will be other network services included in the mix. For example, your public network is already using
it's own DNS server by virtue of Active Directory integration. Your dedicated network for replication traffic may or may not have its own DNS server so configuring the endpoints would involve using either IP addresses like the one highlighted in the
blog post or using hosts file with fully qualified domain names so you can use them when creating the endpoints

Issues enabling AlwaysON in SQL Server 2014 Standard

Hi
I am trying to configure AlwaysOn and having issues enabling in SQL Server configuration manager
OS : Windows Server 2012 R2
SQL : SQL Server 2014 Standard Edition
Here is what i see in config manager :
The AlwaysOn Availability Groups feature requires the x86(non-Wow) or x64 Enterprise Edition of SQL Server 2012 (or later version) running on Windows Server 2008 (or later version) with WSFC hotfix KB 2494036 installed. This SQL Server edition and/or Windows
Server system do not meet one or more of these requirements.
I patched both the nodes and ran the cluster validation as well which didn't report any missing patches. Couldn't find any documentation/solution for this.
Can someone please help me with this ???

Thanks.
Is the configuration of Always on FCI is same as Traditional WSFC ?
Yes just think of it as a regular clustered sql instance
An FCI is a single instance of SQL Server that is installed across Windows Server Failover Clustering (WSFC) nodes
and, possibly, across multiple subnets.
https://msdn.microsoft.com/en-us/library/ms189134(v=sql.110).aspx

Is it possible to move to Alwayson Availability groups from existing sql server FCI ?

Is it possible to move to Alwayson Availability groups from? existing sql server FCI ?
If yes, how to move and what are the pre-requisites?

Hi Rahul,
Based on your description, we need to verify if you want to move from Failover Cluster Instances(FCI) and database mirroring to SQL Server Alwayson Availability groups. If so, it is possible.
You can review the following articles to get more detailed information about this kind of migration.

Types of cluster in ms sql server 2012

Hi,
I am not good in sql server, i got one requirement to migrate standalone ms sql server(which contains replications also) to cluster env, so i have few things to know
1) what are the types of cluster available in ms sql server 2012
2) any steps would be appreciated
BR
PGR

Hi PGR,
Firstly, there are two types of clustering: Active/Active or Active/Passive.
In an Active/Active cluster there will be two or more nodes, each one “owning” an instance of Microsoft SQL Server. If one node fails, the instance it owns would fail over to the other node, running alongside (and contending for resources with) the other instance. Each
copy of SQL Server acts independently.
If one of the SQL Servers in the cluster should fail, then the failed instance of SQL Server will failover to the remaining server. This means that both instances of SQL Server will be running on one physical server, instead of two.
In an Active/Passive setup, at least one node is not the owner of an instance of SQL Server. It is “passive” and only exists to accept a failover of a node hosting a SQL instance in the event of a failover. For more details, please review this blog:
SQL Server Clustering.
Secondly, you can follow the steps in this
blog to move SQL Server from standalone to Cluster environment.
Thanks,
Lydia Zhang
