Hardware Requirement for SQL Server 2012 Cluster

Hi All,
We are going to share System Requirement document with the customer and one of the technical staff from Customer has request us to provide Microsoft Disk space requirement at least for below 2 section and why?
Quorum & MSDTC (Both will be SAN and what will be their RAID type)
Please share your advice.
Regards, Sachin

Hello,
The quorum disk needs only to have a few MB to hold the file used for arbitration. Normally if you're needing a disk vote, it can be extremely small (100MB or less is what most SANs can do, some can only do 1 GB or greater). The actual file size is a few
KBs.
MSDTC holds the DTC logs, so this will be sized to how much logging and usage of MSDTC is needed and used. If you're not using distributed transactions then it doesn't even need setup.

  • Is Distributed Transaction Coordinator services of the application role are required by SQL Server 2012 for clustering and support of SharePoint 2013.

    All I want to know is if Distributed Transaction Coordinator services of the application role are required by SQL Server 2012 for clustering and support of SharePoint 2013.
    I have been planning and deploying my companies first Windows Server 2012/SQL Server 2012 Always On cluster and Always On Availability Groups Multi-Subnet cluster and instances for SharePoint 2013, and I will be brutally honest, the documentation on either
    the MSDN and TechNet leave alot to be desired. Continually finding links in the documentation will take me from a Windows 2012 reference to a page talking about Windows Server 2008 or R2, The differences of which there are so many when it comes to configurations,
    settings, roles, services when working with SQL Server 2012. I have been confused, frustrated, screaming mad, with all the misdirection in this documentation.  The documentation takes me windows 2008 R2 which is different than 2012!
    Tired and trying to pick myself up off the floor!

    In general, DTC is not required for SQL 2012.  But, since you are asking specifically about SharePoint, it would be better to ask in a SharePoint forum.  They would be more likely to know those situations where FTC might be needed by SharePoint.

  • Do we need to format data and log files with 64k cluster size for sql server 2012?

    Do we need to format data and log files with 64k cluster size for sql server 2012?
    Does this best practice still applies to sql server 2012 & 2014?

    Yes.  The extent size of SQL Server data files, and the max log block size have not changed with the new versions, so the guidance should remain the same.

  • Does a sql server client application needs to be modified to allow it to have benefits of running on a SQL Server 2012 cluster?

    I have a client application in c++ which interacts with sql server database. My question is whether I need to make any changes to the client application code to allow it to have the benefits of running on a SQL server 2012 cluster environment. 
    To elaborate more on my query my concern is for e.g if my application has called an api to execute a sql query and during
    the execution of this query the sql server (part of the cluster) goes down then as per my understanding the sql cluster would ensure that another node takes up the task from the current sql server which has gone down. Is this transition transparent to the
    client application or in such a case my client application needs to again make a new connection and again execute the query?

    Hello,
    Just as Shanky post above, When you connected to a database in an availability group and specify the availability group listener in the connection string, if the availability group fails over, the original connection is broken, your application
    should try a new connection after the failover.
    So, when connect to an availability group, please try to increasing connection timeout and implementing connection retry logic to increase the probability of successful connection.

  • Question : Service Accounts for SQL Server 2012

    Hello,
    I am planning to create AD accounts for SQL Server 2012 services that will be installed on Windows 2012 server.
    I was reading the following
    Configure Windows Service Accounts and Permissions
    and
    Windows Privileges and Rights
    Is there a recommendation / document that would list that assocation of SQL Server Services with Actvie Directory service accounts / privileges required for installation and starting the services.
    Isn't it recommended to create separate account for every service and they should not be local accounts ?
    Hope to hear soon as to what industry standards are being followed for production systems ?
    Thank you very much in advance.
    Regards
    Nikunj

    From MSDN:
    Each service in SQL Server represents a process or a set of processes to manage authentication of SQL Server operations with Windows. Each service can be configured to use its own service account. This facility is exposed
    at installation. SQL Server provides a special tool, SQL Server Configuration Manager, to manage the services configuration.
    When choosing service accounts, consider the principle of least privilege. The service account should have exactly the privileges that it needs to do its job and no more privileges. You also need to consider account isolation; the service accounts should
    not only be different from one another, they should not be used by any other service on the same server. Do not grant additional permissions to the SQL Server service account or the service groups.
    From Glen Berry's Blog:
    You should request that a dedicated domain user account be created for use by the SQL Server service. This should just be a regular, domain account with no special rights on the domain. You do not need or want this account to be a local admin on the machine
    where SQL Server will be installed. The SQL Server setup program will grant the necessary rights on the machine to that account during installation.
    You will also want a separate, dedicated domain user account for the SQL Server Agent service. If you are going to be installing and using other SQL Server related services such as SQL Server Integration Services (SSIS), SQL Server Reporting Services (SSRS),
    or SQL Server Analysis Services (SSAS), you will want dedicated domain accounts for each service. The reason you want separate accounts for each service is because they require different rights on the local machine, and having separate accounts is both more
    secure and more resilient, since a problem with one account won’t affect all of the SQL Server Services.
    Depending on your organization, getting these domain accounts created could take anywhere from minutes to weeks to complete, so make sure to allow time for this. For each one of these accounts, you will need their logon credentials for the SQL Server setup
    program. You are going to want to make sure that the accounts don’t have a temporary password that must be changed during the next login. If they are set up that way, make sure to change them to use a strong password, and record this information in a secure
    location.

  • How to uninstall/remove security update for SQL Server 2012

    My requirement is to uninstall/remove security update for SQL

    Go to Control panelàProgramsà
    Programs and FeaturesàInstalled Updrtes, right click on update and uninstall
    As per my knowledge in SQL Server 2005, we cannot uninstall a service pack. we have to uninstall SQL Server 2005 completely, and reinstall SQL Server 2005 with previous service
    packs and updates. but Starting SQL Server 2008, we can uninstall a service pack using Control Panel.

  • Hardware requirements for SQL database used with TestStand

    We are wanting to set up a SQL server to store the data from TestStand.
    How do we determine the hardware requirements for this server? It will be used with 10-30 machines running tests and logging data and another 5-10 machines running queries to pull the data back out for analysis. The result data size will range from 50-25,000 results per run (run times are 1 minute for 50 result tests and 5 hours for the 25,000 result tests).

    Hi,
    database design and hardware requirements are never easy. There are a lot of scientific papers on work load tests and requirement assumptions. I can not give a short answer which machine to use. Just some ideas and starting points.
    The most important parts of a database system with large data sets are network bandwidth, RAM and storage bandwidth. With smaller data sets and more complex transactions the CPU becomes more important.
    In this TS case the data sets are usually rather small. If the queries are not too complex, the requirements seems to be not too high.
    Database performance is usually measured in transactions per minute (tpm). Special database servers can perform several thousands tpm and have costs starting at about 15 $ per tpm. See MS' ad page for a g
    ood starting point: http://www.microsoft.com/sql/evaluation/compare/benchmarks.asp
    You may also visit the TPC.org homepage.
    To be more specific.
    I'd choose a modern Intel-based system like P4-3MHz (that have virtual multiprocessors) with at least 512 MB RAM and a RAID5 hard disk storage system (not nercessarily SCSII) with at least 3 single HDs. Use a 100 MB LAN connection at least, best with a switch. Don't forget backup!
    Check also the pages of your preferred database provider.
    I am on a starting point here too. We have chosen mySQL, which runs (at least now) on the very same machine where TS & LV are running. We plan to test this setup with increasing burden to get a practical assumption of the HW requirements. The planned final setup will have up to 5 test stations and 5 query stations. We'll run about 50 rather complex tests of about 4 hours each that operate in parallel on the test stations.

  • After installed SP1 for SQL Server 2012, can no longer export to csv

    After installing SP1 today via Windows Update, I am no longer able to export data to csv using the SQL Server Import and Export wizard. I get the following error message:
    "Column information for the source and the destination data could not be retrieved, or the data types of source columns were not mapped correctly to those available on the destination provider."
    "Column "col1": Source data type "200" was not found in the data type mapping file."...
    (The above line repeats for each column)
    The work-around I have to do is to manually map each column in the "Edit Mappings..." option from the "Configure Flat File Destination" page of the wizard. This is an extreme inconvenience to have to have to edit the mappings and change
    each column to "string [DT_STR]" type from "byte stream [DT_BYTES]" type each time I want to export to csv. I did not have to do this before installing SP1; it worked perfectly for months with hundreds of exports prior to this update and
    no need to modify mapping.

    I am running Windows 7 64-bit, SQL Server 2012 Express edition. Again, just yesterday from Windows Update, I installed SQL Server 2012 Service Pack 1 (KB2674319), followed by Update Rollup for SQL Server 2012 Service Pack 1 (KB2793634). This situation was
    not occurring before these updates were installed, and I noticed it immediately after they were installed (and of course I restarted my computer after the updates).
    In SSMS I just now created a test DB and table to provide a step-by-step with screenshots.
    Here is the code I ran to create the test DB and table:
    CREATE DATABASE testDB;
    GO
    USE testDB;
    GO
    CREATE TABLE testTable
    id int,
    lname varchar(50),
    fname varchar(50),
    address varchar(50),
    city varchar(50),
    state char(2),
    dob date
    GO
    INSERT INTO testTable VALUES
    (1,'Smith','Bob','123 Main St.','Los Angeles','CA','20080212'),
    (2,'Doe','John','555 Rainbow Ln.','Chicago','IL','19580530'),
    (3,'Jones','Jane','999 Somewhere Pl.','Washington','DC','19651201'),
    (4,'Jackson','George','111 Hello Cir.','Dallas','TX','20010718');
    GO
    SELECT * FROM testTable;
    Results look good:
    id    lname    fname    address    city    state    dob
    1    Smith    Bob    123 Main St.    Los Angeles    CA    2008-02-12

    4    Jackson    George    111 Hello Cir.    Dallas    TX    2001-07-18
    In Object Explorer, I right-click on the [testDB] database, choose "Tasks", then "Export Data..." and the SQL Server Import and Export Wizard appears. I click Next to leave all settings as-is on the "Choose a Data Source" page, then on the "Choose a Destination"
    page, under the "Destination" drop-down I choose "Flat File Destination" then browse to the desktop and name the file "table_export.csv" then click Next. On the "Specify Table Copy or Query" page I choose "Write a query to specify the data to transfer" then
    click Next. I type the following SQL statement:
    SELECT * FROM testTable;
    When clicking the "Parse" button I get the message "This SQL statement is valid."
    On to the next page, "Configure Flat File Destination" I try leaving the defaults then click Next. This is where I am getting the error message (see screenshot below):
    Then going to the "Edit Mappings..." option on the "Configure Flat File Destination" page, I see that all columns which were defined as varchar in the table are showing as type "byte stream [DT_BYTES]", size "0", the state column which is defined as char(2)
    shows correctly however with type "string [DT_STR]", size "2" (see screenshow below):
    So what I have to do is change the type for the lname, fname, address and city columns to "string [DT_STR]", then I am able to proceed with the export successfully. Again, this just started happening after installing these updates. As you can imagine, this
    is very frustrating, as I do a lot of exports from many tables, with a lot more columns than this test table.
    Thanks for your help.
