SQL Server Admin 2014 :: Creating Named Instance On Cluster

Apr 22, 2015

I need to create a named instance on a sql cluster.

How do I perform this? Is it as simple as creating a named instance on a standalone machine? Is there anything I need to consider?

SQL Server Admin 2014 :: Cannot Connect To Named Instance (2nd Instance) From Local SSMS

Jul 22, 2015

I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.

SQL Server Admin 2014 :: Ports Firewalls And A New Named Instance

Nov 12, 2014

I have an existing 2012 default SQL Express. It's set up on a VPS managed by a third party. I have an administrator account on this 2012 Windows server. I'm not much of a sysadmin or a DBA but I get around. ;)

I've installed a new NAMED instance on this VPS and can not connect to it with client tools (SSMS). If I remote in, I can connect this way.

What steps might a seasoned DBA expect to make when getting a new named instance ready for the world.

Assign a port? Check the port?

Open the firewall for the port?

Will this new named instance listen on a different port than the previously installed SQL Express instance?

SQL Server Admin 2014 :: Remote Access To Named Instance

Jul 6, 2015

I try to connect from a pc to a SQL Server on another pc. Both pc’s are in a workgroup. I want to connect from a Windows Forms application to a named instance on the other computer. By now I have been able to connect from one pc to SQL Server on the other with tcp:smurfin, 52782.

I want to be able to use servernameinstancename (instead of portnumber) to make a connection in a Windows Forms application.

I’ve checked / tried te following:

•In the properties of the instance, tab Connections, the option Allow Remote Connections is enabled
•In Configuration Manager: TCP is enabled
•The service SQL Server Browser is started
•On the tab IPAddresses, in the section IPAll, there is NO portnumber for TCP Port. And TCP Dynamic Ports has the nummer 52782
•I have created un inbound rule for port 52782 and also for 1434 (SQL Server Browser). And to be on the save side: a rule for 1433 as well.
•Restarted the service

If I run the following code in SQL Server, that same port number (52782) is returned:

EXEC xp_ReadErrorLog 0, 1, N'Server is listening on', N'any', NULL, NULL, 'DESC'
GO
SELECT local_tcp_port
FROM sys.dm_exec_connections
WHERE session_id = @@SPID

[Code] ....

SQL Server 2012 :: Remove Named Instance From Failover Cluster

Oct 13, 2014

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.

SQL Server Admin 2014 :: How To Configure Named Pipes Protocol Correctly

Oct 5, 2015

I've been reading about the protocols and i've been trying to connect to my SQL SERVER using each one of the protocols, but i think I'm missing something, i dont have any problems using Shared Memory and TCP protocols, but I'm not pretty sure how to connect to my remote SQL SERVER using NAMED PIPES protocols. The books On Line of Microsoft refer that you can connect using this protocol using the next syntax: Connecting to a default instance by specifying a named pipe name:

APPHOSTpipeunitapp

Connecting to a named instance by specifying a named pipe name:

APPHOSTpipeMSSQL$SQLEXPRESSSQLquery

Connecting to default instance by name, forcing a named pipes connection:

np:APPHOST

Connecting to named instance by name, forcing a named pipes connection:

np:APPHOSTSQLEXPRESS

But I can't connect to my remote SQL SERVER, if i try the same with my local SQL SERVER i don't have any problems. I've been reading the articles so many times searching something about Named Pipes is only for local connections, but Microsoft say that it's posible to connect to a remote SQL SERVER, but i don't know how to do that. The firewall is disabled, I changed the APPHOST in the above syntax for the IP address of my SQL SERVER but it didn't work..

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 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.

SQL Server Admin 2014 :: AlwaysOn Secondary Down -> Whole Cluster Goes Down

Oct 25, 2015

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!)

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.

SQL Server Admin 2014 :: Setting Up Aliased Instance Name

Jul 15, 2015

How to set up a specific aliased instance name. I have installed two identical named instances on a server called LONPOCSQL. The instance names are FINPROD and FINREP, so when connection to them remotely I connect to LONPOCSQLFINPROD or LONPOCSQLFINREP. My question is how can I configure it so that I can connect remotely to the instances in by referencing them as FINPRODFINPROD and FINREPFINREP?

The reason for this is that I need to replace a very old system where the applications connect to the sql servers by referencing them as FINPRODFINPROD and FINREPFINREP respectively. I'm trying to set up a 2-node SQL alwayson AG cluster for HA+DR with one server in the prod DC and the other in DR. I need both instances to live one the same box.

1. As far as I'm aware SQL Aliases only work when the connection is local, remote connections fail
2. I can't create a DNS alias called "FINPRODFINPROD" and point it at a listener name as slashes "" are not allowed in DNS CNAMEs
3. My old boss once built a SQL 2008 R2 failover cluster with two instances on it called "lonsql40lonsql40" but there is no documentation on how he did it and I can't find anything on the web

SQL Server Admin 2014 :: Does Each Node Need To Have Same Instance Name For Listener To Work?

Apr 15, 2015

Say I have 2014 AlwaysOn setup and working:

SQLNode1 ->Instance01
SQLNode2 ->Instance02

When I setup my listener: ListenerA...Do I need to use the instance name in it?

ListenerAInstance01 or ListenerAInstance02 depending on which SQLNode is the "active" availability group?

Am I better off to use the same instance name for both nodes, since my goal is to have all databases on both instances in the same availability group and sync'd? When SQLNode1 migrates over to SQLNode2 I will need to update the instance name in my connection string on the listener from ListenerAInstance01 to Instance02? When I connect with SSMS do I just use: ListenerAInstance01 (or 02)?

SQL Server Admin 2014 :: AlwaysOn And Instance-level Items

Jul 16, 2015

How you are handling the replication of the many instance-level objects/items (logins, linked servers, server roles, database mail, operators, on and on) to the replicas in an AlwaysOn topology.

I'm especially curious about DBAs managing larger SQL Server environments. In my current environment, we have approximately 80 production SQL instances containing about 650 databases that require high availability and disaster recovery.

We use mirroring today and have a solid, home-grown solution for replicating the instance-level items from production to disaster recovery. AlwaysOn changes things a bit since we'll have multiple replicas and of course the database could be active on any one of those at any time. So my concern is about instance-level items being created in one instance but never deployed to the other instances participating in the AG group.

SQL Server Admin 2014 :: Using Machine Name Already Exists Error After Cluster Installation Failure

Sep 10, 2015

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.

SQL Server Admin 2014 :: Server Min And Max Memory On Cluster

Oct 9, 2015

I 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 :: Calculating Average Read / Write Latency Across Instance Using Counters

Apr 27, 2015

How you would calculate the average read/write latency experienced by a SQL Server instance during a specific time window in order to monitor this for multiple instances. From this MSDN blog, I know that you have to take multiple samples and do some calculations to get the correct latency.

[URL] ...

However, the SQLServer:Resource Pool Stats object tracks these numbers per resource pool and we want to get one number for the whole server. Since there can be a different base value for each resource pool, you can't simply sum the numerator values together. Here's some sample data from a server that illustrates the problem.

object_name counter_name instance_name cntr_value cntr_type
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) default 307318919 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base default 25546724 1073939712
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) internal 2045730 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base internal 208270 1073939712

I'm thinking I would need to do some sort of weighted average, but I'm not sure if that will result in the correct value. Here's the formula I am thinking about using currently before doing the calculation over time

((default * default[base]) + (internal * internal[base]))/(default[base] + internal[base])

Then to do the calculation over time, I'd use the changes in the calculated numerator and denominator to get the average.

Does this sound like to correct way to get this value? Is there a good way to verify?

Creating A New Named Instance

Sep 7, 2007


As understand it, the only way to add another SQL Express 2005 named instance is to run SQLEXPR32.EXE again. However, when you to, right at the end, you get the following error message:

"An installation package for the product MS SQLK Server VSS Writer cannot be found. Try the installation again using a valid copy of the installation package 'SQLWriter.msi'"

So, I deleted all named instances, and the repeated the procedure and did not get this error and it installed fine. Obviously, I would not be able to delete all instances, but in this case it didn't matter.

So, here are my questions:

Question 1) Am I correct you must rerun SQLEXPR32.EXE to create a new named instance? (I think the answer is yes)

Question 2) Is there a way to rename an existing named instance? (I think the answer is no)

Question 3) The install/uninstall for SQLEXPR32.EXE is incredibly buggy. I have spend days trying to remove an named instance with no succes. Once your remove all named instances from Control Pannel, you stll have not removed SQL Express 2005. How do you remove it? We are considering other avenues because of the incredible problems with this product. Also, we inadvertantly installed SQL Express 2005 Advanced Services, when we meant to install SQL Express 2005, so we would like to uninstall Advance Serviuces and reinstall SQL Express 2005

Question 4) I am switching from the Outlook Express newsgroups to these groups. In the context of these groups, what is the difference betwee a Forum and a Newsgroup?

Thanks
Bob

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}

[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?
