How to install SSAS Cluster instance with Always On availability group(Standalone database instance) in same windows cluster servers
We have requirement like to Install the SSAS as Cluster instance where SQL Server Database engine was installed with Always On availability group.Please help me to how configure it
Currently we have following configuration in Current steup.
Node1 and Node2 are in windows cluster
Node1 has SQL Server Database engine Instance1 as Standalone
Node2 has SQL Server Database engine Instance2 as Standalone
Instance1 and Instance2 configured for Always On availability group with Listener.
Now we have to steup SSAS instance with High availibilty. I know we have only option is to install cluster SSAS instance.
Can some one provide information below.
1. How to steup Cluster SSAS instance in this servers.
2. Is this will have any dependancy on exisiting Listner name.
3. Is this affects the availiblity groups, if SSAS instance failed over to another node.
Thanks in Advance
Sriram
You will need to have SSAS installed as a clustered instance with shared storage. Refer to the whitepaper from this MSDN article
How To Cluster SQL Server Analysis Services
Availability Group is in it's own Role/Resource Group. When you create the clustered SSAS, it will create its own Role/Resource Group. This means that it will require its own virtual network name and virtual IP address and will not affect the existing Availability
Group. You can also have it on the existing Availability Group if you want to. However, you need to decide if you want SSAS to failover with the Availability Group or not. Your design choices will depend on that decision.

How do I remove a node from Always on Availability Group in SQL 2012
Hello I was wondering if anyone could tell me to remove a node from an AOG group in SQL 2012. We currently have a two node Always on availability group and I need to replace one of the servers. My plan is to bring the
new server on to the group then remove the old server and I am having issues finding documentation on this. Could someone explain how to do this or if it is even possible.
ThanksAfter the new server is added to the cluster and the AG, remove the old one by first
ALTER AVAILABILITY GROUP [YourAG]
REMOVE REPLICA ON N'OldServer';
Remove a Secondary Replica from an Availability Group
Then evict the old server from the cluster with the cluster administrator or
Remove-ClusterNode OldServer
Remember to verify the quorum configuration after adding the new server and removing the old server.

Cannot connect to SQL SERVER with Always on availability group listener name
Hi everyone,
I have setup always an availability group listener for sql server on port 1433, have opened the port in firewall , remote connections are enabled in the sql server, but still I am not able to connect to the sqlserver instance with the help
of the availability group listener name.
I get the following error.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider:
TCP Provider, error: 0 - The wait operation timed out.)"} System.Exception {System.Data.SqlClient.SqlException
Have gone through several blogs for the solution but none of them helped.
Please let me know if anyone has fixed the issue.
Regards,

Extra Availability Group Or Extra Instance
Hello all,
We've implemented AlwaysOn High availability, an AV Group on three servers. Now we want one server to host sql activity too.
This can be done by creating a second availability group with its primary role on the second server or by creating another instance with its own availability group.
Does anyone have any special things to consider which solution we could choose?
Kind regards,
Fred Koene>Does anyone have any special things to consider which solution we could choose?
If you can share sysadmins for the two databases, and they can be on the same version and patch level, then you should put the new AG on the existing instances.

How to install 9ifs into 9idb with 9iAS 1.0.2.2.2a in window 2000?
Anyone know how to install 9ifs into 9idb with 9iAS 1.0.2.2.2a?
Hi,
9iFS must be installed in an 9i home type. So you must have it installed in a single box in your 9i DB home. You must use the Apache server of the DB, because the installer will modify the configuration files of this Apache, not this of 9iAS.
After just modify the port the 9i apache is listening (use 81 instead of 80 for example).
Be careful that if you install a new apache for the 9i database, your vw_gateway_cfg environment variable will be changed and will point to the 9i home instead of the 9ias home. So you have to change it back to your 9iAS home if you want to use the portal !!!!

Some Quick clarification about 2012 and always on Availability groups
Hi guys, just need some clarification about always on.
I've got plenty of experience with normal SQL Clusters, but just need some clarification around always on availability groups.
I presume with AG, you setup a listener and this becomes your point of connection, IE this is what you use in the you connection string for you applications, so can I use this when I am setting up a new application, and will this automatically make the Database
that's created by the APP, Highly available. ? or do you still have to add it to the AG afterwards. ?
I have also read that you can still point to the installed SQL instance, and you don't need to use the AG group listener, but how does this make your DB HA ? how does the failover work.
I also presume you don't need to use any roles under the MSC anymore.
Kind regards
Mark.GHi Mark
I presume with AG, you setup a listener and this becomes your point of connection
That's right, the listener is a virtual network name and you can use this to connect to the primary or secondary replica. Your connections will go in against the primary unless you're using
read-only routing.
so can I use this when I am setting up a new application, and will this automatically make the Database that's created by the APP, Highly available
The first thing you'll have to do is set up the availability group (AG). You can then associate a listener to the AG. I know you're familiar with failover clustering but the mechanics of this are much closer to database mirroring. For every database that's
part of the AG you'll have at least one secondary replica, it's possible to automatically failover to this if you're in synchronous mode.
I have also read that you can still point to the installed SQL instance, and you don't need to use the AG group listener, but how does this make your DB HA ? how does the failover work.
Yes you can do, but from an application perspective you should only do this for databases that are not part of an AG. If you connect to the instance directly and you have a failover your app will no be able to connect to the database (on the assumption your
secondary isn't read-only). App connections should always be via the Virtual Network Name.
I also presume you don't need to use any roles under the MSC anymore.
Not sure I understand this? Do you mean will roles be available in cluster manager? Each AG group will have a role but failover is now controlled through the SQL Server rather than the cluster manager. -
Always on Availability groups using static SQL Tcp Port
Hi, I have 2 SQL 2012 servers in my DMZ and I have assigned SQL to run on a static TCP Port. I would like to setup Always On availability groups on the servers but I cannot get the failover to work with the static TCP port. It works fine
with dynamic ports.
When the failover is initiated it attempts to connect to the secondary replica with out using the static port, can someone tell me how to setup the availability group using static tcp ports.
Thanks,When I setup the secondary replica I added the port number, but it doesn't appear to use it for failover. I add the secondary replica w/o errors.
I am not sure how to add the port number to the primary.
Dave
Hi Dave,
Based on your description, could you please post the error message when getting failover to the secondary replica?
In addition, If you use the default port of 1433 for availability group listener VNNs, you will still need to ensure that no other services on the cluster node are using this port; otherwise this would cause a port conflict.
If one of the instances of SQL Server is already listening on TCP port 1433 via the instance listener and there are no other services (including additional instances of SQL Server) on the computer listening on port 1433, this will not cause a port conflict
with the availability group listener. However multiple instances of SQL Server (side-by-side)should not be configured to listen on the same port.
For more details, please review this article:
Availability Group Listeners, Client Connectivity, and Application Failover (SQL Server).
Thanks,

SQL 2012 Always On Availability Groups
Has anyone configured FIM SYnc, FIM Service and MSF in SQL 2012 Always On Availability groups
I do not believe we can configure the SQL connection string for FIM Sync or FIM Service to include "multisubnetfailover"
TIA
NigelI commented on this here:https://social.technet.microsoft.com/Forums/en-US/64f55628-3b5d-4d16-9044-dcbe7053581d/lack-of-support-for-fim-database-mirroring?forum=ilm2
Additional comments:
SQL Server Always On Failover Cluster Instances should be supported just as SQL Clustering is supported.
SQL Server Always On Availability Groups are not supported, just as Database Mirroring in synchronous mode (which is required for automatic failover) is not supported. I can't find authoritative statements of this on the web. But I know this to be the
case.
Ultimately, the reason for lack of support for mirroring (for automatic failover or in synchronous mode) is that the product group has said so (in conferences and webinars). Meaning the product group has not tested it or has and decided that it doesn't
work or adds risk.
Possible underlying reasons:
1) To do automatic failover with mirroring or Availability groups you must edit the connection string. The way FIM builds the connection string out of the components in the registry don't permit this.
2) Running mirroring in synchronous mode slows down performance in two ways: first is the additional traffic to send it to the mirror partner (or replica), second and most important is that synchronous requires that the primary not truly commit the transaction
until it has been committed to the secondary which means transactions take longer. For some products this can result in an unacceptable performance degradation.
Hopefully, MIM will support Availability groups.

Hello everyone!
I am currently planning to implement SQL Always On Availability Groups.
Mainly i have one sql server so apparently i need to setup a new sql server.
In the wizard there is a page where I need to select Initial data synchronization full or join.
What’s the difference?? Is choosing the full option requires me to provide a Third server to temporarily store my database so my 2 main SQL server can sync for the first time? And if yes can I remove this shared location (Third server) after the database
are synced??
Thank You.Join option only if the new
secondary databases already exist on each server instance that hosts a secondary replica for the availability group. That is you have manually restore a recent database backup of the primary database using RESTORE WITH NORECOVERY, and then restore each
subsequent log backup using RESTORE WITH NORECOVERY.
Full option
creates a full and log backup of the primary database, create the corresponding secondary databases by restoring these backups on every server instance that is hosting a secondary replica, and join each secondary database to availability group.
When you use full you have to
specify a network share folder in order for the wizard to create backups and secondary replica will access backups to perform restores from this stage. Yes you can remove the share once the all databases are in sync. -
Setting Up Alerts for Always on Availability Groups Failover
Hi Folks,
In SQL Server 2008R2 we set up alerts for Mirroring failover using WMI Alerts. As Like this.
Now we need to configure similar alerts for Always on Availability Groups(AAG) in SQL Server 2012, but it seems that there is no such WMI Alerts or any standard way to set up the alerts for getting notified for AAG Failover. Click
Here
Should I manually Create a SQL Agent Job using
these DMVs and schedule it at frequent Interval to get notified about any AAG failover or is there any standard way as for mirroring Failover alerts? Any suggestion or help is appreciated.

Sql 2012 always on availability group use cases
i have setup the always on availability group between 2 sql servers.
in the primary site, my app is connected to the primary site.
The DB is in an always on group replicated to the secondary site.
so what is the use of the secondary replica for?
If the primary db server goes down, what will happen?
Can apps use the replica db? but its read only
what is the purpose of this?I agree with David.

We have a MSSQL 2008R2 Enterprise edition with a two node active passive fail-over cluster running on 2008R2 windows cluster with out any issues,
Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setuphi,
>>Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
Yes it is possible .You need to add new drives as cluster aware and install SQL server and put data and log files on thse drives.YOu would need to create named instance of SQL server and need to create different resource group.Both old installation and new
onw would work separately.
>>Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
Good point indeed.You are about to create Multi instance cluster and should plan for scenario where one node is down and other node is handling load for both instances.Memory and CPU should be enough to handle the load.
>>Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setup .
Just for collation if you are installing new instance seems little wierd to me.You can manage collation at column ,database and at server level.
