Hyper-v Failover clustering for SQL Server lab
Hi,
After 20yrs years of IT software experience, now I am realizing that I don't know much about hyperV clustering. :) I am trying to setup a lab. I badly need help on configuring network adapters
to make the machines accessible from each other. Please see details below:
I have a laptop with 8gb ram with windows 8.1 hyper-V. I created 4 VMs with Windows 2008r2 on it and further I intend having SQL Server Failover Clustering. VM details are as below:
DC - Domain Controller
SanStorage - MS iSCSI target
Win1 - Primary node in the cluster that will have SQL Server instance
Win2 - Secondary node in the cluster that will have SQL Server instance.
The laptop has 1 Qualcomm network adapter (generally used for connecting Lan cable) and a Broadcomm (wifi) adapter. I intend setting up three virtual adapters
First for regular communication
Second for Data (SQL Server Data to be stored on SCSI)
Third for HeartBit
Normally, (on my laptop) I connect to internet using Broadcomm (Wi-Fi) and want to ensure that whenever needed:
Run this lab even when Lan or wifi is NOT connected. If one of them is mandatory then even that could be the option.
I should be able to use internet within all VMs as well- though this is good to have requirement.
Internet needs to be available on laptop at least. Even if it is unavailable in VMs that is ok.
Now the actual problem.
I DON'T KNOW how many virtual internal/external/private switches to be
defined and assigned to individual VMs. What should be the IPs, Subnets, DNS, Gateways defined on those?
I was able to setup the stuff up-to certain extend and then it stopped working for unknown reasons. I have VMs ready. Next what should I do? Steps...
setup network adapters in each VM
setup DNS on DC
Add remaining 3 VMs in domain
Define Win1 and Win2 as cluster
Configure Target
Configure initiators and access the target
e. Install SQL Server
Is above correct?
My queries probably demands a separate article. But I have already referred many articles and couldn't figure it out so posting it here. I sincerely request your help!
PS – Even after disabling firewall (with and without having DNS setup) I am unable to ping VMs from each other.

ThingToLearn
Thanks, Pravin
Hi,
You need create another guest vm as the NAT device, attach the NAT external to the Wifi adapter or cable adapter, then you can set all your vms in internal network
vswitch.

2 Node Hyper-V failover cluster with sql server
I have 2 IBM Servers with Server 2012 installed and both machines have SQL server express. Is it possible to create HYPER-V Failover between the 2 servers including the SQL SERVER Instance meaning if the main node fails the second server will take over.
The second will act as virtualized failover of the main node with failover instace to act as active to active approach.

Sure you can do that. But it's a long story what's better SQL Server FCI or AlwaysOn. See:
FCI Vs. AlwaysOn
http://msdn.microsoft.com/en-us/library/ff929171.aspx
(biggest issue with AlwaysOn - it does require Enterprise license so is COSTY)
Good idea to ask here:
SQL Server High Availability and Disaster Recovery
http://social.technet.microsoft.com/Forums/sqlserver/en-us/home?forum=sqldisasterrecovery
In any case you'll need either physical or virtual shared storage. For FCI to host everything and witness disk and for AlwaysOn just for witness (AlwaysOn does replication between DAS on it's own).
Good luck :)

HI
how to do analysis server clustering
we have sharepoint bi site and we published many dashboards pointers ,filters kpis
and at a time some 200 to 300 concurrent users access these dashboards pages
so for maintain this requirement how we apply clustering for ssas intances
and also it has load balancing
adilHi Adil,
According to your description, you want to implement SQL Server Analysis Services Clusster and Analysis Services Load Balancing, right?
In SSAS, we can design highly available solutions in Analysis Services by using: network load balancing (NLB) technologies, failover clustering technologies, or both. For the details about implemention, please refer to the links below.

Specifying Partner Failover in odbc.ini for Linux ODBC driver for SQL Server
Hi,
We are trying to specify the partner failover when making connections via Linux ODBC driver for SQL Server. Do you know a way to specify partner failover in the DSN entry in odbc.ini?
We are using Linux ODBC driver for SQL Server and unixODBC DriverManager.
Our DSN is:
[MyDSN]
Driver=ODBC Driver 11 for SQL Server
Description=MyDSN
Server=MySERVER,<port>
I also tried to use the following connection string in Python (via pyodbc) bypassing the DSN and connecting using the server name.
cnxn = pyodbc.connect("Server=server1,<port>;UID=sa;PWD=<pwd>;Driver=ODBC Driver 11 for SQL Server;Failover_Partner=Server2,<port2>;Database=MyDB")
If the standby DB is on server1 connection fails. It doesn't try server2. If the DB is principal on server1 connection succeeds.
Thank you,
Liviu
LLLHello,
Did you use ODBC Driver for SQL Server to connect to database that uses database mirroring?
According to
the BOL,it does not list "Failover_Partner" as ODBC Driver for Linux connection string keywords.
But ODBC driver for Linux supports
AlwaysOn Availability Groups or Failover Cluster Instance by specify MultiSubnetFailover=True when connecting to a SQL Server 2012 availability group listener or SQL Server 2012 Failover Cluster Instance.
The following case is about similar issue and it seems that ODBC Driver on Linux does not recognize Failover_Partner in connection string. (Not test myself).You can refer to:

The Buzz from Microsoft Ignite 2015
NetApp was in full force at the recent Microsoft Ignite show in Chicago, talking about solutions for hybrid cloud, and our proven solutions for Microsoft SQL Server and other Microsoft applications.
Hot topics at the NetApp booth included:
OnCommand® Shift. A revolutionary technology that lets you move virtual machines back and forth between VMware and Hyper-V environments in minutes.
Azure Site Recovery to NetApp Private Storage. Replicate on-premises SAN-based applications to NPS for disaster recovery in the Azure cloud.
These tools give you greater flexibility for managing and protecting important business applications.

Director, EIS Technical Marketing, NetApp
If your organization runs databases such as Microsoft SQL Server and Oracle DB, you probably know that these vendors primarily license their products on a "per-core" basis. Microsoft recently switched to "per-core" rather than "per-socket" licensing for SQL Server 2012 and 2014. This change can have a big impact on the total cost of operating a database, especially as core counts on new servers continue to climb. It turns out that the right storage infrastructure can drive down database costs, increase productivity, and put your infrastructure back in balance.
In many customer environments, NetApp has noticed that server CPU utilization is low—often on the order of just 20%. This is usually the result of I/O bottlenecks. Server cores have to sit and wait for I/O from hard disk drives (HDDs). We've been closely studying the impact of all-flash storage on SQL Server environments that use HDD-based storage systems. NetApp® All Flash FAS platform delivers world-class performance for SQL Server plus the storage efficiency, application integration, nondisruptive operations, and data protection of clustered Data ONTAP®, making it ideal for SQL Server environments.
Tests show that All Flash FAS can drive up IOPS and database server CPU utilization by as much as 4x. And with a 95% reduction in latency, you can achieve this level of performance with half as many servers. This reduces the number of servers you need and the number of cores you have to license, driving down costs by 50% or more and paying back your investment in flash in as little as six months.
Figure 1) NetApp All Flash FAS increases CPU utilization on your SQL Server database servers, lowering costs.
Source: NetApp, 2015
Whether you're running one of the newer versions of SQL Server or facing an upgrade of an earlier version, you can't afford not to take a second look at your storage environment.
End of Support for Microsoft SQL Server 2005 is Rapidly Approaching
Microsoft has set the end of extended support for SQL Server 2005 for April 2016—less than a year away. With support for Microsoft Windows 2003 ending in July 2015, time may already be running short.
If you're running Windows Server 2003, new server hardware is almost certainly needed when you upgrade SQL Server. Evaluate your server and storage options now to get costs under control.
Test Methodology
To test the impact of flash on SQL Server performance, we replaced a legacy HDD-based storage system with an All Flash FAS AFF8080 EX. The legacy system was configured with almost 150 HDDs, a typical configuration for HDD storage supporting SQL Server. The AFF8080 EX used just 48 SSDs.
Table 1) Components used in testing.

Source: NetApp, 2015
The test configuration consisted of 10 database servers connected through fibre channel to both the legacy storage system and the AFF8080 EX. Each of the 10 servers ran SQL Server 2014 Enterprise Edition.
The publicly available HammerDB workload generator was used to drive an OLTP-like workload simultaneously from each of the 10 database servers to storage. We first directed the workload to the legacy storage array to establish a baseline, increasing the load to the point where read latency consistently exceeded 20ms.
That workload was then directed at the AFF8080 EX. The change in storage resulted in an overall 20x reduction in read latency, a greater than 4x improvement in IOPS, and a greater than 4x improvement in database server CPU utilization.
Figure 2) NetApp All Flash FAS increases IOPS and server CPU utilization and lowers latency.
Source: NetApp, 2015
In other words, the database servers are able to process four times as many IOPS with dramatically lower latency. CPU utilization goes up accordingly because the servers are processing 4x the work per unit time.
The All Flash FAS system still had additional headroom under this load.
Calculating the Savings
Let's look at what this performance improvement means for the total cost of running SQL Server 2014 over a 3-year period. To do the analysis we used NetApp Realize, a storage modeling and financial analysis tool designed to help quantify the value of NetApp solutions and products. NetApp sales teams and partners use this tool to assist with return on investment (ROI) calculations.
The calculation includes the cost of the AFF8080 EX, eliminates the costs associated with the existing storage system, and cuts the total number of database servers from 10 to five. This reduces SQL Server licensing costs by 50%. The same workload was run with five servers and achieved the same results. ROI analysis is summarized in Table 2.

Source: NetApp, 2015
The takeaway here is that you can replace your existing storage with All Flash FAS and get a big performance bump while substantially reducing your costs, with the majority of the savings derived from the reduction in SQL Server licensing costs.

Maximum SQL Server 2014 Performance
In addition to the ROI analysis, we also measured the maximum performance of the AFF8080 EX with SQL Server 2014. A load-generation tool was used to simulate an industry-standard TPC-E OLTP workload against an SQL Server 2014 test configuration.
A two-node AFF8080 EX achieved a maximum throughput of 322K IOPS at just over 1ms latency. For all points other than the maximum load point, latency was consistently under 1ms and remained under 0.8ms up to 180K IOPS.
Data Reduction and Storage Efficiency
In addition to performance testing, we looked at the overall storage efficiency savings of our SQL Server database implementation. The degree of compression that can be achieved is dependent on the actual data that is written and stored in the database. For this environment, inline compression was effective. Deduplication, as is often the case in database environments, provided little additional storage savings and was not enabled.
For the test data used in the maximum performance test, we measured a compression ratio of 1.5:1. We also tested inline compression on a production SQL Server 2014 data set to further validate these results and saw a 1.8:1 compression ratio.
Space-efficient NetApp Snapshot® copies provide additional storage efficiency benefits for database environments. Unlike snapshot methods that use copy-on-write, there is no performance penalty; unlike full mirror copies, NetApp Snapshot copies use storage space sparingly. Snapshot copies only consume a small amount of storage space for metadata and additional incremental space is consumed as block-level changes occur. In a typical real-world SQL Server deployment on NetApp storage, database volume Snapshot copies are made every two hours.
First introduced more than 10 years ago, NetApp FlexClone® technology also plays an important role in SQL Server environments. Clones are fully writable, and, similar to Snapshot copies, only consume incremental storage capacity. With FlexClone, you can create as many copies of production data as you need for development and test, reporting, and so on. Cloning is a great way to support the development and test work needed when upgrading from an earlier version of SQL Server. You'll sometimes see these types of capabilities referred to as "copy data management."
A Better Way to Run Enterprise Applications
The performance benefits that all-flash storage can deliver for database environments are significant: more IOPS, lower latency, and an end to near-constant performance tuning.
If you think the performance acceleration that comes with all-flash storage is cost prohibitive, think again. All Flash FAS doesn't just deliver a performance boost, it changes the economics of your operations, paying for itself with thousands in savings on licensing and server costs. In terms of dollars per IOPS, All Flash FAS is extremely economical relative to HDD.
And, because All Flash FAS runs NetApp clustered Data ONTAP, it delivers the most complete environment to support SQL Server and all your enterprise applications with capabilities that include comprehensive storage efficiency, integrated data protection, and deep integration for your applications.
For complete details on this testing look for NetApp TR-4303, which will be available in a few weeks. Stay tuned to Tech OnTap for more information as NetApp continues to run benchmarks with important server workloads including Oracle DB and server virtualization.

With just these generic error messages being present, this has been difficult to diagnose. Some research has yielded possible resolutions of the Event Viewer log being full, .NET corruption, missing registry entries, but none of those seem to be the issue
(Event Viewer logs cleared, Analysis services is working on the same physical servers in a different cluster, and the registry entries was only a supported issue for SQL Server 2008 and 2008 R2).
Any help would be greatly appreciated.Bring up Configuration Manager, look at binary path for SSAS. Make sure BOTH folders exist. Sometimes with failovers mappings get screwed up.

Cluster resource 'SQL Network Name (SQLCLUS1)' of type 'Network Name' in clustered role 'SQL Server (DB1)' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
I keep getting this error message. Can someone please help. Thank You.
Kranp.Hi Kranp,
As the issue is more related to Windows Server high availability
, I recommend you post the question in the
Windows Server High Availability (Clustering)
forum. It is appropriate and more experts will assist you.
Besides, there are similar threads regarding to the above error for your reference.

Group managed service accounts for SQL Server
Hey guys,
Unfortunately I missed that (g/s)MSAs aren't supported yet for SQL Servers but I'm using them without any worries since ages.
As i digged a bit deeper I could find different informations due to the related TechNet entrys. So it seems Microsofts Informations about (s)MSAs and gMSAs aren't consistent.
I'm not a SQL Server guy and use SQL only for System Center testing stuff so i would like to get a real world exps of SQL Server guys.
Should I continue using gMSAs or are there any worries I should know?
some sources I found so far:
Not supported:
"Hi Adam,
Thank you for your feedback. Windows Server 2012 Group Managed Service Account is not currently supported as SQL 2012 released earlier than Windows Server 2012. We will consider to support gMSA in future SQL Server release.
Regards,
Min He, Program Manager, SQL Server"

gMSA are not yet available, are not yet supported for SQL Server. gMSA exist and are available and supported in Windows Server 2012 and higher. SQL does not support them , but
from an OS perspective, they exist and are supported.

The MSA must be created in the Active Directory by the domain administrator before SQL Server setup can use it for SQL Server services.
others sources won't mentioning s/gMSAs...
I couldn't find clear informations about using gMSA for SQL Server 2014.

HADR Solution for SQL Server Analysis Services (SSAS) 2014 on Azure Iaas
Hi All
I am required to build a HA/DR solution for SQL Server and SSAS 2014 on Azure. So far I could build AlwaysOn high availability solution for SQL Server on Azure but haven't found any solution for SSAS.
Failover Clustering is not an option on azure because of the restriction of not been able to use shared storage. We also determined that the cost savings of using SQL + the cost of the 3rd Party replication tool was a wash (ie no real cost savings).
Any lead on this would be appreciated.
Thanks,
Viral Shah
Thanks - ViralHi Viral,
A clustered implementation of SSAS can be configured in Microsoft Azure. Such a configuration would need to meet all the requirements stated in the following document including Active Directory and storage.

HI,
I have installed Cumulative Update 12 for SQL Server 2008 R2 SP2 on my SharePoint instances. This was to resolve a known issue faced with the instance. CU12 helped resolve the issue. My company is rather strict regarding security hotfixes. But I am
not sure if this particular hotfix [Security Hotfix (KB2977319)] is required if the instance has CU12 applied.
Tested this on a Lab server, the installation did run fine, the summary log also stated that the KB is applied. But the Build Number did not change. Hence the doubt.

John SYes you must install Security update mentioned in KB 2977319 it is important for SQL Server to be patches with this security update. Without this it could allow an attacker to compromise your system and gain control over it.

Hello everyone.
I'm using SQL Server 2014, and writting on some C++ app to query and modify the database. I use the ODBC API.
I'm stuck on inserting an SQL_NUMERIC_STRUCT value into the database, if the corresponding database-column has a scale set.
For test-purposes: I have a Table named 'decTable' that has a column 'id' (integer) and a column 'dec' (decimal(5,3))
In the code I basically do:
1. Connect to the DB, get the handles, etc.
2. Use SQLBindParameter to bind a SQL_NUMERIC_STRUCT to a query with parameter markers. Note that I do include the information about precision and scale, something like: SQLBindParameter(hstmt, 2, SQL_PARAM_INPUT, SQL_C_NUMERIC, SQL_NUMERIC, 5, 3, &numStr,
sizeof(cbNum), &cbNum);
3. Prepare a Statement to insert values, something like: SQLPrepare(hstmt, L"INSERT INTO decTable (id, dec) values(?, ?)", SQL_NTS);
4. Set some valid data on the SQL_NUMERIC_STRUCT
5. Call SQLExecute to execute. But now I get the error:
SQLSTATE: 22003; nativeErr: 0 Msg: [Microsoft][ODBC Driver 11 for SQL Server]Numeric value out of range
I dont get it what I am doing wrong. The same code works fine against IBM DB2 and MySql. I also have no problems reading a SQL_NUMERIC_STRUCT using SQLBindCol(..) and the various SQLSetDescField to define the scale and precision.
Is there a problem in the ODBC Driver of the SQL Server 2014?
For completeness, here is a working c++ example:
// InsertNumTest.cpp
// create database using:
create a table decTable with an id and a decimal(5,3) column:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE[dbo].[decTable](
[id][int] NOT NULL,
[dec][decimal](5, 3) NULL,
CONSTRAINT[PK_decTable] PRIMARY KEY CLUSTERED
[id] ASC
)WITH(PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON[PRIMARY]
) ON[PRIMARY]
GO
// Then create an odbc DSN entry that can be used:
#define DSN L"exOdbc_SqlServer_2014"
#define USER L"exodbc"
#define PASS L"testexodbc"

If this is no solution try increasing the decimale number on the SQL server table, if you stille have the same problem after that change the column to a nvarchar and see the actual value that is put through the ODBC connector for SQL. -
Help! Licence for SQL Server 2008 VM on Windows 2012
I am confused by latest Microsoft Virtual server licence for SQL Server 2008.
We have a Hyper-V host running Windows Server 2012 R2 Datacenter. Displayed in its Task Manager, it has 16 cores and 32 logical processors (with hyper-threading turned on). A SQL Server VM is running on this host with 10 Virtual processors (showing from Hper-V
Manager). The SQL Server edition is SQL Server 2008 Standard.
We are using "Per Core Licensing Model". Now, the question is how many licences we need to purchase for the above SQL Server?
There are "SQL Server 2008 Licensing Guide", "Microsoft SQL Server 2012 Virtualization Licensing Guide" and "Microsoft SQL Server 2014 Licensing Guide". But none of them covers this scenario, which is running SQL Server 2008 on
Windows 2012 Hyper-V host Server.
Could you please provide me your opinion: Should I license 10 cores for the SQL Server VM or license 5 cores (because the hyper-threading on physical server) ? Thank you very much in advance!I am confused by latest Microsoft Virtual server licence for SQL Server 2008.

I have used SSRS a lot years ago with Sql Server 2000 and Sql Server 2005. I have written external assemblies, ... But now I have to do this with Sql Server 2008 (R2 -- which I realize I am way behind the times already but ...) in sql server 2000 and
2005 there was a tab for datasource to the left of the tab for design which was to the left of the preview tab. How do I get to the datasource window in sql server 2008 (r2) ?
I see that datasource explorer. But where can I get to the datasource window to edit my queries and so forth for sql server 2008 (R2)?
Thanks
Rich PI think I found the answer to my question --- just right-click on the the Data Sources or Datasets for editing connections and dataset queries. I'm guessing it gets even fancier with Sql Svr 2012 - 2014. Man, that's the one thing
about coding platforms -- you let it go for a few years and come back, and everything has changed (well, a lot of things). Now I need to figure out how to add an external assembly to SSRS 2008 (R2).
