In reply to Carl Webster. Thank Carl, have you tried doing a BAG without WSFC? It seems that this can be done in SQL 2017 where you can only utilize BAG. Although in my experience the listener does not seem to work, without WSFC.

In reply to Albert. No. One Listener per AG and each AG contains one database. So, one Listener per database. Site database -> AG -> Listener Monitoring database -> AG -> Listener Config database -> AG -> Listener Webster

So basically, you have created 3 different listeners for each database? I’ve tried this on our lab and I can only add 1 listener per AG.

In reply to Abert He. You missed a link. High availability There are several high availability solutions to consider for ensuring automatic failover:

AlwaysOn Availability Groups (including Basic Availability Groups)

SQL Server database mirroring

SQL clustering

Using the hypervisor’s high availability features

Sir,
The presentation of database support is not very clear.

https://support.citrix.com/article/CTX114501

The x86 and x64 versions of SQL (version 2012 and later) have been validated with Always On, Clustered, Standalone and Mirrored modes.

I think 7.15 support:
1-Always On
2-Clustered
3-Only one SQL server
4-Mirrored

But in the following the article, there is not cluster, it only supports alwayOn.

https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/system-requirements.html

The following database high availability solutions are supported (except for SQL Server Express, which supports only standalone mode):

SQL Server AlwaysOn Failover Cluster Instances
SQL Server AlwaysOn Availability Groups (including Basic Availability Groups)
SQL Server Database Mirroring

In reply to Pavan. Hi Pavan It is the same procedure, only that it is not done by database, the databases are added to the arrangement

A very thorough helpful article. I thankyou you for sharing and putting in the time to document this process. And now that SQL 2017 is out BAGS can be used with 2 versions of SQL and folks are finding out that this is a good cost saving solution over Enterprise licensing.

In reply to Pavan. I do not know. I have yet to setup AAG. Webster

Hello Carl,
Thank you for the article. Really helpful. We can pretty much follow the same procedure for setting up Always ON Availability groups as well right?
Thanks&Regards,
Pavan

In reply to Engin Yoruker. Always On is different than Basic Availability Groups. It may work but when something bad happens, don't expect Citrix support to offer any help for an unsupported configuration. Webster

In reply to Engin Yoruker. Absolutely. I checked with the person directly in charge of PVS at Citrix. Webster

In reply to Carl Webster.

Are you sure about PVS is not supported?

It’s not saying BAG specifically, but..

In reply to Engin Yoruker.

I have not tried it. At this time, as of PVS 7.11, BAGs are not officially supported by any version of PVS. They may work but without official support, I would not use them.

Thanks

Webster

Hi,
Wondering have you tried this also for PVS database? Is that also supported?

In reply to Sebastian. Sorry but I just do not know. I know enough about SQL to get the basics done. Webster

In reply to Sebastian. strange issue, the database on the second sql server is not created, no error while creating the group. could this be a language problem?
