Transactional replication from a failover cluster instance to a SQL Server Express DB

Hello,
I have been poking around on Google trying to understand if there are any gotchas in configuring transactional replication on a instance DB of a failover cluster, to a SQL Server Express DB. Also, this client would like to replicate a set of tables between
two instances DB's which both reside on nodes of the cluster.
Everything I've read suggests there is no problem using transactional replication on clustered instance as long as you use a shared snapshot folder. I still have some concerns:
1) Should the distributor need to live on a separate instance?
2) What happens in the event of an automatic, or manual failover of a publisher, especially if the distributor does not need to live on a separate instance? I know that when a failover occurs, all jobs in progress are stopped and this seems like a recipe for
inconsistency between the publisher and subscriber.
There is a paramount concern, that this particular client won't have staff on hand to troubleshoot replication if there are problems, hence my hesitancy to implement a solution that relies on it.
Thanks in advance.

1) Should the distributor need to live on a separate instance?
Answer: It is recommended to configure the distributor on the different server, but it also be configured on Publisher/subscriber server. (Subscriber in our case is not possible as its a Express edition)
2) What happens in the event of an automatic, or manual failover of a publisher, especially if the distributor does not need to live on a separate instance? I know that when a failover occurs, all jobs in progress are stopped and this seems like a recipe for
inconsistency between the publisher and subscriber. There is a paramount concern, that this particular client won't have staff on hand to troubleshoot replication if there are problems, hence my hesitancy to implement a solution that relies on it.
Answer: If you configure both publisher and distributor on the same server and the SQL instance is failed over, the data synchronization/replication is suspended till the instance comes online.
Once the instance is up,all the replication jobs will start again and it will continue to synchronize the data to subscriber. No manual intervention is required.

Dedicated network for AlwaysON replication traffic when a replica is a Failover Cluster Instance

Hi,
We are planning to setup dedicated network for our Availability Group replication traffic. We have a Failover Cluster Instance as the primary replica and a standalone SQL server instance as the secondary.
I understand that we will need to manually configure the database mirroring endpoints on both the replicas to listen on the specific IP.
But how do I configure the database mirroring endpoint on the Failover Cluster Instance ?
Please help.
Thanks and Regards,
Jisha

If you have a dedicated network for your Availability Group replication traffic between the FCI and the standalone instance, you need to identify if there will be other network services included in the mix. For example, your public network is already using
it's own DNS server by virtue of Active Directory integration. Your dedicated network for replication traffic may or may not have its own DNS server so configuring the endpoints would involve using either IP addresses like the one highlighted in the
blog post or using hosts file with fully qualified domain names so you can use them when creating the endpoints

Exploring AlwaysOn Failover Cluster Instances in SQL Server 2014 Tecnet Labs

I like the Labs and have found them very usful. I have a problem with: Exploring AlwaysOn Failover Cluster Instances in SQL Server 2014. The lab starts but hangs on opening SQLONE and the Manual never loads. I have tried coming out and starting again but
get returned to the same failing session. I thought I would mention it here as the is no way to feedback a response as the appraisal only happens once the lab is completed, i.e. no apparent link on the lab site. The session ends when the HOL is reported

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

Transactional replication from SQL Server 2014 to Sybase 12.5

Hi All,
Is it possible to set up replication between SQL Server 2014 and Sybase 12.5 in which SQL server would be the publisher and Sybase as subscriber.
Regards..
aa

Hi Ashif,
According to this
blog, it is possible to set up transactional replication from SQL Server to Sybase.
To achieve this, you could set up transactional replication via the Sybase OLE DB driver after you set up Sybase as a
linked Server.
For how to set up transactional replication, please refer to the article:

2 Hyper-V Servers with Failover Cluster and a single File Server and .VHDs stored on a SMB 3 Share

I have 2 X M600 Dell Blades (100 GB local storage and 2 NICs) and a Single R720 File Server (2.5 TB local SAS storage and 6 NICs). I´m planning a Lab/developer enrironment using 2 Hyper-V Servers with Failover Cluster and a single File Server putting
all .VHDs stored on a SMB 3 Share on the File Server.
The ideia is to have a HA solution, live migration, etc, storing the .VHDs onm a SMB 3 share
\\fileserver\shareforVHDs
It is possible? How Cluster will understand the
\\fileserver\shareforVHDs as a cluster disk and offer HA on it?
Or i´ll have to "re-think" and forget about VHDs on SMb 3 Share and deploy using iSCSI?
Storage Spaces makes difference in this case?

You can do what you want to do just fine. Hyper-V / Windows Server 2012 R2 can use SMB 3.0 share instead of a block storage (iSCSI/FC/etc). See:
Deploy Hyper-V over SMB
http://technet.microsoft.com/en-us/library/jj134187.aspx
There would be no shared disk and no CSV just SMB 3.0 folder both hypervisor hosts would have access to. Much simplier to use. See:
Hyper-V recommends SMB or CSV ?
http://social.technet.microsoft.com/Forums/en-US/d6e06d59-bef3-42ba-82f1-5043713b5552/hyperv-recommends-smb-or-csv-
You'll have however a limited solution as your single physical server being a file server would be a single point of failure.
You can use Storage Spaces just fine but you cannot use Clustered Storage Spaces as in this case you'll have to take away your SAS spindles from your R720 box and mount them into SAS JBOD (make sure it's certified). So you get rid of an active components
(CPU, RAM) and keep more robust all-passive SAS JBOD as your physical shared storage. Better then a single Windows-running server but for a true fault tolerance you'll have to have 3 SAS JBODs. Not exactly cheap :) See:

Alternative way would be using Virtual SAN similar to VMware VSAN in this case you can get rid of a physical shared storage @ all and use cheap high capacity SATA spindles (and SATA SSDs!) instead of an expensive SAS.
Hope this helped :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

SQL Server Express Performance Limitations With OGC Methods on Geometry Instances

I will front load my question. Specifically, I am wondering if any of the feature restrictions with SQL Server Express cause performance limitations/reductions with OGC methods on geometry instances, e.g., STIntersects? I have spent time reading
various documents about the different editions of SQL Server, including the Features Supported by the Editions of SQL Server 2014, but nothing is jumping out at me. The
limited information on spatial features in the aforementioned document implies spatial is the same across all editions. I am hoping this is wrong.
The situation.... I have roughly 200,000 tax parcels within 175 taxing districts. As part of a consistency check between what is stored in tax records for taxing district and what is identified spatially, I set up a basic point-in-polygon query
to identify the taxing district spatially and then count the number of parcels within in taxing district. Surprisingly, the query took 66 minutes to run. As I pointed out, this is being run on a test machine with SQL Server Express.
Some specifics.... I wrote the query a few different ways and compared the execution plans, and the optimizer always choose the same plan, which is good I guess since it means it is doing its job. The execution plans show a 'Clustered Index Seek
(Spatial)' being used and only costing 1%. Coming in at 75% cost is a Filter, which appears to be connected to the STIntersects predicate. I brute forced alternate execution plans using HINTS, but they only turned out worse, which I guess is also
good since it means the optimizer did choose a good plan. I experimented some with changing the spatial index parameters, but the impact of the options I tried was never that much. I ended up going with "Geometry Auto Grid" with 16 cells
per object.
So, why do I think 66 minutes is excessive? The reason is that I loaded the same data sets into PostgreSQL/PostGIS, used a default spatial index, and the same query ran in 5 minutes. Same machine, same data, SQL Server Express is 13x slower than
PostgreSQL. That is why I think 66 minutes is excessive.
Our organization is mostly an Oracle and SQL Server shop. Since more of my background and experience are with MS databases, I prefer to work with SQL Server. I really do want to understand what is happening here. Is there something I can
do different to get more performance out of SQL Server? Does spatial run slower on Express versus Standard or Enterprise? Given I did so little tuning in PostgreSQL, I still can't understand the results I am seeing.
I may or may not be able to strip the data down enough to be able to send it to someone.

Tessalating the polygons (tax districts) is the answer!
Since my use of SQL Server Express was brought up as possibly contributing to the slow runtime, the first thing I did was download an evaluation version of Enterprise Edition. The runtime on Enterprise Edition dropped from 66 minutes to 57.5 minutes.
A reduction of 13% isn't anything to scoff at, but total runtime was still 11x longer than in PostgreSQL. Although Enterprise Edition had 4 cores available to it, it never really spun up more than 1 when executing the query, so it doesn't seem
to have been parallelizing the query much, if at all.
You asked about polygon complexity. Overall, a majority are fairly simple but there are some complex ones with one really complex polygon. Using the complexity index discussed in the reference thread, the tax districts had an average complexity
of 4.6 and a median of 2.7. One polygon had a complexity index of 120, which was skewing the average, as well as increasing the runtime I suspect. Below is a complexity index breakdown:
Index

Before trying tessellation, I tweaked the spatial indexes in several different ways, but the runtimes never changed by more than a minute or two. I reset the spatial indexes to "geometry auto grid @ 32" and tried out your tessellation functions
using the default of 5000 vertices. Total runtime 2.3 minutes, a 96% reduction and twice as fast as PostgresSQL! Now that is more what I was expecting before i started.
I tried using different thresholds, 3,000 and 10,000 vertices but the runtimes were slightly slower, 3.5 and 3.3 minutes respectively. A threshold of 5000 definitely seems to be a sweet spot for the dataset I am using. As the thread you referenced
discussed, SQL Server spatial functions like STIntersect appear to be sensitive to the number of vertices of polygons.
After reading your comment, it reminded me of some discussions with Esri staff about ArcGIS doing the same thing in certain circumstances, but I didn't go as far as thinking to apply it here. So, thanks for the suggestion and code from another post.
Once I realized the SRID was hard coded to 0 in tvf_QuarterPolygon, I was able to update the code to set it to the same as the input shape, and then everything came together nicely.

SQL Server Express 2008 instance fails to start

I've installed SQL Server Express with a named instance 'SQLSERVER2'. I was able to connect to it and reference it in the management studio. There was a problem though with Visual Studio 9 when running an ASP.NET web application that required connecting to the same instance. So, I went into the configuration manager to change the security level of the instance from network to local service. The change went through but could not restart the instance. That is what has created my next round of problems. I can't go in and change it back to network because the instance is permanently stopped. I cannot start it with the services manager. How can I fix this?

Hi,
This problem can occur if the new Service Account does not have a profile on the machine. To resolve the issue connect to the SQL Server machine using the New Service account. This will create a profile for the user.
SQL Server creates a self-generated certificate if a certificate is not explicitly specified and/or is not installed. This information is saved in the profile for the SQL Server service account. If the profile has not been created then SQL cannot register the self-generated certificate.
If there are any more questions, please let me know.
Thanks.
***Xiao Min Tan***Microsoft Online Community***
What 'New Service account' are you referring to? SQL Server Express resides on my PC where I'm logged on as administrator. I don't know what you mean by connecting to the server. I only know about connecting to the database instance which is the root of the this problem because it can't be started. Sorry for my confusion...

I can't see sql server express 2012 from ssms 2008 R2 -- what do I need to download?

I'm running sql server 2008 R2 Developer on a win7 (pro) workstation. I would like to keep this installation because it has SSRS and Analysis Server. But I was not able to attach a sql 2012 DB so I downloaded Sql Server Express 2012 (per the
picture below - 1st option selected) and installed it. Sql Server Express 2012 appears to be running -- per my services list, but I cannot see the instance in ssms 2008 R2. Do I need to uninstall Sql Server Express 2012 and then download another
option (from the picture below)? How should I proceed so that I can have a working/workable instance of Sql Server Express 2012 that I can see in ssms (whatever required version) and also keep sql server 2008 R2? which download should I select (from
the picture below?
Rich P

Should I uninstall Sql server 2012 first?
Rich P
No you do not need to uninstall any thing
>> Sql Server Express 2012 appears to be running -- per my services list, but I cannot see the instance in ssms 2008 R2.
You need to just download SQL Server 2012 express management studio and use that to connect to SQL Server 2012. And use SSMS 2008 r2 to connect to SQL Server 2008 r2.
This File :ENU\x64\SQLManagementStudio_x64_ENU.exe
Although I guess SSMS 2012 express with SP2 would work just fine and you would connect to 2008 R2 database using that.

Hi Jithendar,
For your issue, you can retrieve the SQL Server Evaluation Period Expiry Date to varify which server SSRS has been expired:
SELECT
create_date AS 'SQL Server Install Date',
DATEADD(DD, 180, create_date) AS 'SQL Server Expiry Date'
FROM sys.server_principals
WHERE name = 'NT AUTHORITY\SYSTEM'

My work load has brought me to the place where I need to be using the full blown SQL.
I have backed up my databases (in the Express instance) and am looking for an 'upgrade' path.
Can I install another instance of (full deal of SQL) on the same machine?
Andy

Hello,
Yes, you can perform a side-by-side upgrade by installing another instance of SQL Server (a full licensed/paid edition)
and them move the databases to the newly installed instance by using backup/restore or detach/attach.
https://msdn.microsoft.com/en-us/library/ms189625.aspx
Make sure the new instance has applied the same updates/service packs of the Express instance.
You can have up to 50 instances/installations of SQL Server (standalone) on the same computer.
Alternatively you can perform an edition upgrade from Express to any licensed/paid edition.

Hope this helps.
