Migarting SQL cluster to SQL high availability

September 16, 2019, 4:35 am

Hi

Our current SQL server setup runs with 3 X Windows 2016 servers in failover cluster with 2 X SQL instances. All applications refer the SQL by "Instace\SQLSrvrName". Our management asks to migrate all these clustered instances to SQL high availability model because of various including limitation with backup to take clustered hosts. We never configured SQL high availability, looking for an option to migrate the clustered / multiple instance SQL to high availability with minimum downtime. Also it's hard to change the SQL server reference in all apps, so if possible we have to keep the same format even after migrating to SQL HA model.

Thanks in advance

Hi,

For a user with local admin rights, is there any difference to run SQL setup As Admin vs runnig the setup without this option? I read somewhere in the past that we should never run the setup with 'As Admin' option, I am installing SQL with 'As Admin' option and never face any issue, do you know a case when this could generate an issue or this is just a myth ?

Best regards

Import query execution plan from SQL Server 2008 to SQL Server 2017 instance

Hi,

Recently we have upgraded our production instance from SQL server 2008 to SQL Server 2017. All Query and Stored procedures are running fine except one query is running slow in new instance after up-gradation. In SQL Server 2008 the query takes 7 minutes to execute but in 2017 it takes 50 minutes to executes.

If I change the compatibility level of the 2017 instance to 100 (2008) then the query take 7 minutes to executes.

I need to keep the database compatibility level 140 (2017). Is there any way I can run this particular query with compatibility level 2008. 

I saw some site trace flag '9481' can be enable in SQL Server 2014 to run query behave like 2008. Is there any similar trace flag for SQL Server 2017?

Or is there any way to export the query plan from SQL Server 2008 instance and import to SQL Server 2017?

Regards

Arif

I'm not envisaging any issues, however are there any gotchas or caveats that I should be aware of from someone who has done this?

Server Upgrade

Greetings!

I am in the process of upgrading all of my servers from Server 2008R2 to Server 2012 as a transitional step to eventually getting my shop to Server 2016.

One of my servers is running SQL Server 2008R2 (10.50.6560).  I am thinking that I should upgrade the Windows Server to 2012 first before upgrading SQL Server.  Is this OK?

Thanks,

Ken

Hi All,

I have tried to connect to Linux server using AD authentication  and i could do it successfully by following the link

https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-active-directory-auth-overview?view=sql-server-2017

Scenario 1: I can connect to the Sql server which is installed on Linux using SSMS with windows authentication by using a domain account Domain name\Test account. But i couldn't do any action (ex: Creating db ,accessing database etc..) even though it has SYS Admin permission. Getting errors like "account doesn't have permission", "User do not have permission to perform this action" etc..

Scenario 2:I can connect to Sql server which is installed on Linux using SSMS with WA by using Domain name\Testaccount2 and i can do any action(ex: Create db ,accessing database etc..).

LDAP Account Name :Testacccount2 had sudo access on Linux machine.

Here my AD account name and LDAP account name is matching and i could all SYS admin operations.

Scenario 1 is not working and scenario 2 is working. Is this expected behavior or limitation in SQL Linux. Kindly help if there is any way to make work Scenario 1.

Please let mw know if needed more details.

Thanks is advance!

SQL Server 2016 huge performance difference between two identical servers with same setup

September 26, 2019, 1:21 am

I have two identical physical servers:

ProLiant DL360 Gen9 (Intel Xeon E5 1620 v2, 2 sockets, 8 cores, 16 logical processors, RAM 256 GB)

Windows Server 2012 R2

SQL Server 2016 (CU8)

And I experience a huge performance difference in som agent jobs (SSIS) where the execution time is 2 to 4 times longer on one of the servers. Here to mention it is the same "code" behind in the SSIS package.

My colleagues and I have tried several things already which did not help. The last couple of days I focused on the network side of things and I have found a difference in the setup. I do not know if it is relevant but I would like to adjust the systems so I know they are "really" identical.

So on the slow machine when checking the ports listning:



Compare to the "good" server and all my test servers.



Anyone have an idea why on the bad system I have TCP 0.0.0.0:1434 listening instead of TCP 127.0.0.1:1434? And TCP [::]:1434 instead of [::1]:1434.
I have not found anywhere where I could change this setting in SQL. Any suggestions? Or is this somewhere in the "Windows" TCP / IP settings I need to change to get this setup the same way.

Thx

Stefan

Error installing Microsoft ODBC Driver 17 for SQL Server

I am trying to install SQL Server Management Studio ver 18.3 on a server running Windows Server 2012, but the installation aborts with the following error message - "Fatal error during installation (0x80070643)", with the follow up instruction of "Microsoft ODBC Driver 2017 for SQL Server: Please install the Visual C++ 2017 Redistributable from https://aka.ms/vs/15/release/vc_redist.x64.exe".

However, Visual C++ 2017 is installed on the server.

I then tried to install ODBC Driver 2017 directly with the msi file from MS, but it too aborts with this error message - "Error 1723. Please install the Visual C++ 2017 Redistributable from https://aka.ms/vs/15/release/vc_redist.x64.exe before running this installer."

I appear to be caught in a installation loop. 

Has anyone come across this before? I appreciate any suggestions.

Thanks,

Herman

I'm trying to add features to an existing instance of SQL Server, and the feature that I want to add is Analysis Services.  SQL Server 2017 Express has already setup a local instance of SQL Database Server (v.14.0.2027.2).  In step #8, why isn't Analysis Services listed as a "feature selection"?  Thanks!

SQL Server 2017 edition downgrade warning

Hello,

I have a SQL Server Evaluation version installed for which the evaluation period has expired.

I downloaded the ISO from the Open Licence account (with a SQL Server 2017 Standard Licence)

When installing,

-> Maintenance

-> Edition Upgrade

-> (the product key is filed), next

-> accept license terms, next

-> I specify the only instance (Edition: Evaluation, Version: 14.0.2027.2

The rule check in Progress stop at about 80%

-> Show Details:

SQL Server 2017 edition upgrade: Passed

SQL Server 2017 edition downgrade: Warning

Upgrade architecture mismatch: Passed

Always On Availability Groups feature check (no status listed)

The warning details are:

Rule "SQL Server 2017 edition downgrade" generated a warning.

The selected edition downgrade path is not valid. The source Evaluation edition and the target Standard edition is not a supported path.

according to:

https://docs.microsoft.com/en-us/sql/database-engine/install-windows/supported-version-and-edition-upgrades-2017?view=sql-server-2017

SQL Server 2017 (14.x) Evaluation Enterprise** to SQL Server 2017 (14.x) Standard is supported, (there is no cluster)

Is my problem due to the licence expiration, and how to I solve that ?

Apply SPs and CUs first? Or just Upgrade?

October 1, 2019, 6:19 pm

I have a SQL Server estate with servers in various major versions, SPs, and CUs.  I want to get all of them up to SQL 2017 + latest CU.  I am aware of the minimum versions required for upgrade to 2017:

<style>table {mso-displayed-decimal-separator:"\."; mso-displayed-thousand-separator:"\,";} tr {mso-height-source:auto;} col {mso-width-source:auto;} td {padding-top:1px; padding-right:1px; padding-left:1px; mso-ignore:padding; color:black; font-size:11.0pt; font-weight:400; font-style:normal; text-decoration:none; font-family:Calibri, sans-serif; mso-font-charset:0; text-align:general; vertical-align:bottom; border:none; white-space:nowrap; mso-rotate:0;} </style>
SQL Server 2008 SP4 or later
SQL Server 2008 R2 SP3 or later
SQL Server 2012 SP2 or later
SQL Server 2014 or later

SQL Server 2016 or later

Most servers meet these requirements.  My question is: Would it be best to apply the latest SPs and CUs for the current major versions as a stepping stone to the upgrade to 2017?  OR to just move forward with ensuring that they have the minimal SPs and CUs and then upgrade them straight to 2017?

TIA,

-Peter

Hello,

We are currently preparing for a new SQL Server 2017 Standard for our site (Internal Site).

We are buying a Server + CAL licensing model for the SQL Server to install on our server, but we found that one of our devices is using iPad to access the database through our application.

We are buying 5 devices CAL for the SQL Server, which we are wondering if this can be used/install on an iPad.

Since we are using express edition in the past, we would like to know if the CAL will work on an iPad or other android devices.

Thanks for your help.

Changing SQL Server 2016 edition problem

October 3, 2019, 5:40 am

Hi

I am trying to change the edition of SQL from Enterprise Evaluation to Standard, which is supported according to this article: https://docs.microsoft.com/en-us/sql/database-engine/install-windows/supported-version-and-edition-upgrades?view=sql-server-2017 . This is a single instance, no clustering.

I have downloaded the SQL Server 2016 Standard SP2 ISO from my volume licensing portal and run the Edition Upgrade option.

After running through the wizard, it says it has completed successfully, however when I look at the properties of the instance it is still Enterprise Evaluation.

I tested this scenario on another computer and it worked fine, so I don't know why it isn't working on this other machine.

The version is 2016 SP2 running on Windows Server 2016.

I have noticed that the Database Engine is missing from the 'Ready to upgrade edition' window during the wizard. Perhaps this could be the issue?

Hope someone can help.

Thanks
