LYnc 2013 sql witness collocation

Hi,
I have 1500 users, 3 FE server, 2 edge servers, 2 peristent chat, 2 back end, 1 sql witness.
instead of installing sql witness on separate server, want collocate it with any server, basically want to save the one windows license...any idea?

You can colocate it on any server as long as it's not either of the two SQL servers that you use for Lync. So if you have another SQL server floating around that is not part of your topology and is at the appropriate version (even if it's SQL Express)
you can use that.

Lync 2013 SQL Backend Witness replacement

Can we replace backend SQL witness server via lync 2013 topology builder as H/W of existing witness server needs to be released due to some technical reason.
We don’t prefer P2V. I want fresh installation of SQL witness server with SQL 2012 express edition and then move the witness role
What is the procedure for the same?
Please help me for the same

Hi,
deploy the new SQL server which dedicated for Witness. Configure the topology and associate the new SQL server as the witness server and publish. remove the old SQL store which was configured as the Witness form the topology.

Lync 2013 SQL Mirroring

I have Lync server 2013 SQL mirroring in place. My firm is looking to decrease our SQL server count. Can I collocate none Lync databases on the Mirror Lync SQL instance? Thanks.

Hi TTMing,
It’s not recommend collocating Lync Server databases with other databases, this might affect availability and performance.
Form https://technet.microsoft.com/en-us/library/gg398990%28v=ocs.15%29.aspx?f=255&MSPPError=-2147217396
“If you collocate Lync Server databases with other databases, we highly recommend assessing all factors that might affect availability and performance, as well as ensuring that, if one node fails, the remaining node can handle the load. To verify failover

Lync 2013: SQL instance - Shared or Not Shared !?

I'll keep this straight to the point... I'm implementing Lync 2013 at my company and we stumbled on one SQL Cluster situation that's causing some questions on the DBA team.
So the situation is....
Background:
We currently have a two node SQL 2008 R2 (SP2) Cluster with two instances in it that are shared for other applications.
Question:
Is it recommended by Microsoft (or any Lync Expert at all) to use one of these instances for Lync 2013 databases, or should it be a separated instance to host Lync 2013 Databases?
Note: If to be created the new instance, that instance will be living in the same cluster.
Thank you all in advance for comments on this.

Thanks to both for the replies. It does help me thinking about the subject.
I've meanwhile opened an advisory case with MS to check what they say about it. (I'm posting the results afterwards of course to share their advice)
I agree with both of you, and in fact I don't really like the idea of having a shared instance for Lync 2013 with other products (specially one of them that's in there that is Sharepoint 2013). I'm quite curious on knowing how will the instance behave once
Sharepoint 2013 decides to "eat up" all the resources...
I think that having the separated instance adds at least 2 very good (and important values) that is:
1 - Security (at the instance level.. no unwanted sysadmin's - we have persistent chat by some God forsaken reason... though I don't like the idea that a DBA with the right knowledge to read our C*O's chat's going around...)
2 - Resource assignment control (better memory control, possibility of "shifting" the instance to another place if necessary + if someone "brings down" the shared instance for any reason, lync can continue to function)
The IO concern regarding lots of SQLServer.exe running around, it's also a valid concern in my opinion, though at IO level is basically the same story because what matters is the DB file read-write operations that are ongoing and that will consume the same
resources either you're in a dedicated instance or separated one...
Still our DBA brings up the fact that we need to use a shared instance for everything and he wants me to put Lync all together with the other DB's (Sharepoint 2013 included...).
What are your thoughts about this?
Thanks once again for your time and comments.

Lync 2013 SQL versus Exchange Archiving

Our organization has setup an internal lab for Lync and is trying to decide what the best option would be for deploying archiving with Lync and what the pros vs cons are.
We currently have one Lync 2013 FE Server and an Exchange 2010 server, which I already know does not support archiving. Would it be best to deploy a SQL server for archiving or upgrade Exchange 2010 to 2013? We can do either, but was is the recommended approach
and best practice/pros/cons?
I was planning on utilizing SQL server as the preferred for approach and so we don't have to upgrade Exchange -- just seems easier and will keep any additional load off the Exchange server and once deployed to a production environment.
Thanks.

Agree with Michael.
This data stored in Archiving database is not searchable, but it can be exported to formats that are searchable using other tools.
You can check the difference between these two archiving options at

CMS Movement from Lync 2010 to Lync 2013 SQL Mirroring

Hi,
I have read the articles and i know how to move CMS to Lync 2013 , MY question is after moment CMS to Lync 2013 , the new DBs on SQL server will be mirrored automatically or i have to apply some procedure to make them mirror.
Regards
Usman Ghani
Usman Ghani - MCITP Exchange 2010

Good morning,
If the new Lync 2013 Enterprise Pool you deployed has a mirrored backend, then when you move the CMS to that instance the database will inherently be mirrored. There is no requirement to perform any additional action or procedure.
This assumes that you have an enterprise Lync 2013 deployment as a mirrored CMS would not be available on a standard edition deployment.
Kind regards
Ben

Lync 2013 SQL Permission after install

We have started to install Lync 2013 Enterprise to replace our Lync 2010 Standard servers. Since we are moving to enterprise I've had to ask the SQL dba to get envolved with the installation. We followed the recommended permission document here..
http://technet.microsoft.com/en-us/library/gg398375.aspx
we gave the install account Sysadmin and local admin on the SQL server.
Now that the install is complete our dba wants to remove sysadmin from the account and remove it from SQL.
Can we do that or does it need to stay in place?
Thanks,
Matt

Hi Matt,
You should be able to remove it now that the databases have been created as it should only be required for installation. You just need to make sure that your users accounts for management are part of the appropriate RBAC groups.
The only caveat I can think of is if you need to do some SQL configuration tasks like deploy mirroring or run an update that may need to drop and rebuild the database. In those scenario you would need to have it reapplied.

Lync 2013 sql mirroring with different doamin sql server.

Hi,
can I create lync BE sql mirroring with different domain sql server with one AD forest?
Thanks.

Hi,
You can note the sentence “Using Topology Builder or cmdlets to set up and remove SQL mirroring is supported only when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers
in different domains, see your SQL Server documentation.” In the link below:
http://technet.microsoft.com/en-us/library/jj204992.aspx
So I think in Lync server if you use Topology Builder or cmdlets to set up and remove SQL mirroring only if when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers in different
domains you may do some steps on SQL server and you can also post a case on SQL forum, thank you for your understanding.

Lync 2013 sql database on existing lync 2010 sql server

Dear All,
I have query regarding the SQL server requirement for Lync 2013 enterprise,when there is a co-existence or migration from lync 2010 to 2013, it it possible to use the same Lync 2010 enterprise sql server with different instance name or we have to create
a new sql server for lync 2013, please advice me.
Thanks and regards,
sarma kumar

No it is not possible. Topology builder won't allow it, it needs to be a completely different server name.
When you input the server into Topology builder you enter the server name and instance in two separate fields, it will give you a red X as soon as you try to put the server name in if it's already in the topology.

Lync 2013 SQL requirements

I have a SQL environment which is used for web apps, ERP, CRM and other databases. Can I install my Lync SQL environment onto this SQL server? is this scenario supported?
or do I need dedicated and separate Lync SQL servers?

It's recommended to use a separate SQL server for Lync (Physical of Virtual), however collating Lync database with other SQL databases will work. Considering the cost of SQL licenses, this is not uncommon.
It is important in either scenario that the SQL servers have adequate resources/performance to be able to handle the load from Lync server in addition to anything else it will be doing.
Also note that if you have multiple front end pools, these cannot share a SQL server. (and creating another instance on the same SQL server also does not work)
Take a look at the Technet information for more: http://technet.microsoft.com/en-us/library/jj205112.aspx and http://technet.microsoft.com/en-us/library/gg398835.aspx

Licensed required for LYNC 2013, Sql, Edge

for 1500 users for IM presence, audio video, HA, DR, archive
proposed design :- archive collacted with backend,
DC:- 2 FE server, 2 Edge server, 2 Sql Mirrored,
DR :- 1 FE, 1 Edge, 1 SQL
is there any flaw in sizing?
Licenses :- 3 FE license, (FE in DR will need license as it is passive?)
3 SQL licenses :- how to calculate it per core, in my case how much core and how many licenses required?
thx

Yes, you'll need 3 Lync licenses (you only license the front end and passive will need to be licensed).
For SQL, yes 3 servers. This article will help calculate your core licensing:
http://www.microsoft.com/licensing/about-licensing/briefs/licensing-by-cores.aspx
Sizing is fine provided everything has adequate resources. 3 FEs in the DC pool is recommended.

SQL Mirroring Requirement (Witness server) in LYNC 2013

Hi Everyone,
We are designing a Highly Available solution of for LYNC 2013 and planning to add a witness server to the backed SQL server.
Following are my Queries.
1)For the witness server should the SQL server be dedicated to the LYNC infrastructure or it can be used to host other databases.
2)I am assuming the Witness Database should be in the same Domain?
3)What is the version of the SQL server that is supported as the Witness server, can this be the Free SQL express edition ?
Waiting for some replies :-)

Lync 2013 and SQL 2012 on the same server

Hi,
I'm in the process of migrating Lync 2010 to Lync 2013. I have a clean install of Windows Server 2012 R2. Is it possible to install Lync 2013 and SQL 2012 on the same server or does it have to be on separate servers.
Thanks
P

Configure Separated SQL Server to use in an Enterprise deployment of Lync Server. Standard Edition servers use a collocated SQL Server Express version of SQL Server that is right sized for the workloads of a Standard Edition server.

How to fetch presence in Lync 2013 from SQL server (using query)

We are running Lync 2013 setup with 5 FE and 2 BE SQL (mirrored) servers.
How can i get presence information for our users by script or SQL queries?
My Concern is to fetch out current presence information of a list of users (CSV file) by script (Powershell or SQL query) for automation purpose. So that one need not to go to Lync 2013 (or anything) Client for every single user, to check their corresponding
presence.
E.g Say a service desk agent is handling tickets of 200 users per day. So it will be time consuming for him/her to go to Lync 2013 client and check presence for every user. It would be better for SD agent to operate, if we could make a script to fetch presence
status for the list of 200 users.
We will fetch the information when required and send a mail to him/her.
i have asked this question under Presence and IM forum.
https://social.technet.microsoft.com/Forums/en-US/ef6287d1-e474-48ab-a411-f3813d256145/how-to-fetch-presence-information-in-lync-2013?forum=lyncprofile
been suggested to post it here.

Create a Store procedure which will give you integer value according to presence status:
USE [rtc]
GO
/****** Object: StoredProcedure [dbo].[GetAvailability] Script Date: 05/01/2015 10:36:35 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: <sudipta samanta>
-- Create date: <02.01.2015>
-- Description: <fetch presence information of user>
-- =============================================
CREATE PROCEDURE [dbo].[GetAvailability]
@_Publisher varchar(50)
AS
DECLARE
@agrregate_state varchar(500),
@availability varchar(50),
@index_first int,
@index_last int,
@index int
BEGIN
SET NoCount ON
set @agrregate_state = (select top 1 Data from dbo.DiagPublisherDataView(@_Publisher) order by LastPubTime desc);
set @index_first = (select CHARINDEX('<availability>',@agrregate_state));
set @index_last = (select CHARINDEX('</availability>',@agrregate_state));
set @index = @index_first + 14;
set @availability = (SUBSTRING(@agrregate_state,@index,@index_last - @index));
return CONVERT(int, @availability);

SQL Server 2012 Standard Support for Lync 2013

Hi,
Does SQL 2012 Standard version support Lycn 2013 , I am planning to have following features.
1- SQL 2012 Mirroring
2- Monitoring Role on FE Servers

Agree with Anthony, SQL 2012 Standard support Lync 2013.
For Standard or Edition Edition of SQL that according to High availability node of Database that you want.
Two-node failover clustering for the following:
Microsoft SQL Server 2012 Standard (64-bit edition). Additionally running the latest service pack is recommended.
Microsoft SQL Server 2008 R2 Standard (64-bit edition). Additionally running the latest service pack is recommended.
Up to sixteen-node failover clustering for the following:
Microsoft SQL Server 2012 Enterprise (64-bit edition). Additionally running the latest service pack is recommended.
Microsoft SQL Server 2008 R2 Enterprise database software (64-bit edition). Additionally running the latest service pack is recommended.
