SQL 2012 :: Can't Find Online To Setup AlwaysOn From Scratch
Apr 29, 2015
I am trying to setup alwayson on 2008r2 server on 2 instances in the same machine fort testing purpose. I installed 'Failover Cluster Manager' now I don't see 'Nodes' to add up.Should I run 'Validate a configuration Wizard'? or something else.. Can't find online to setup 'Alwayson' from the scratch...Will I able to setup 'Always on' on same server but different instances like mirroring? or has to be different servers?

I'm setting up my first pair of Sql 2012 servers using AlwaysOn. I set up backups to run on the primary and I understand that you can set up backups to run on both the primary and secondary servers but the secondary will fail. Is there a way I can stop the secondary server from sending out error messages about failed backups? Is it possible to script it so that the server looks at whether it's primary or secondary and turns on or off alerts based on that?

We have an existing SQL Server 2012 Enterprise cluster with 2 nodes (active-active) and uses Windows 2008 R2 OS. We are looking for a way to increase HA as well as offload backups to secondary server and it was suggested that AlwayOn could be an option.
The questions I have are:
1) Is it possible to turn on AalwaysOn feature on an existing cluster?
2) If yes to above, does the secondary replica need to exist as a node on the same cluster or can it be on a completely different cluster?
3) If the secondary replica is on the same cluster (i.e. we add a 3rd node to existing 2 node cluster), can that node be provisioned with storage from a completely different SAN? (i.e. Node 1 and Node 2 accesses LUNs on SAN1 and Node 3 accesses LUNs on SAN2).

How to find when (date/time) a database was last removed from AlwaysOn Listener?
Is there any query (DMV) to find the details easily?

We have a client which they have production 2 node cluster environment. On it around 200 databases with single SQL instance.
Now client wants disatster plan for these 200 database. In these 200 database 3 db's are around 80 GB each databases remaing are less than 5 DB.Note: All these 200 db's are having produciton sites (i mean to say each db is having single site)
For this DR paln clinet is going to provide other DR server,they wants to setup DR between exsting produciton cluster instance to this DR server.
So in this case we have suggest SQL server AlwaysOn availability group.
Here my main question is can we keep all these databases in single AG? .If yes, guidlines to move up. if not, do we have any limitations.Also, best method to setup for this DR plan.

Though to setup Alwayson, it is necessary to have both SQl Instances to be in same version, same database file path , etc.But, is this possible to setup the AlwaysOn between a default and a named instance?

We have a database with AlwaysOn enabled, where the database is getting mirrored using AlwaysOn to a secondary node in a two node cluster. Now we want to set up a DR site for that database in a different data center.
So trying to analyse what technologies. We can use for setting up the DR for that database. Can we use mirroring / replication or what's the best way of setting up DR on that database.

I have configured AlwaysOn HA setup with HyperV environments without shared disk and using quorum voting in file share witness.
1. I want to monitor AlwaysOn HA setup and AO Group database on daily basis.
2. To configure email alerts for proactive monitoring if unusual events occur.
Scripts for monitoring in that AO setup as well as AO group database ...

OS - Windows 2012 R2 Standard Edition.
DB - SQL 2012 Enterprise edition
Total 3 nodes participates for AO setup, 2 Nodes for Local HA and 1 Node for another datacenter for DR. All the 3 Nodes are same domain name and member.
1. Local First 2 Nodes are same subnet XXX.XX.44.XX
2. DR Node another subnet XXX.XX.128.XX
Does it require to add two different IP address while creating cluster name? Not using shared disk SAN storage etc.. I am using Node majority quorum witness setting for failover.

I have an active passive cluster on my primary Data center in NY and have a DR Active / passive SQL Cluster in TX. These are two separate clusters in the same domain using the same SQL server credentials.Both clusters host an active / passive SQL instance. Lets call it SQLNY(Primary) and SQLTX (DR). I want to enable always On Availability group within the two SQL Instances SQLNY and SQLTX. The listener will be SQLAG which will be used by the Application to connect to the SQL instance. Is there a practical way to implement this? This will not only give me instant fail over within the NY (Primary) but also give me the flexibility to fail over to TX. I am using SQL 2014 Enterprise Edition on both clusters.

HI! Thank you for even looking at this question.
I need to get a website up and running for a small group of people. I've had SQL Server for a while, but didn't have any use for it. It came with Visual Studio 2005, which gave me a little know how on scripting. Now, I have Visual Web Developer and what I need to make a web page. I just need to know how to configure all my settings to allow my website to be viewed online by anyone with an internet connection. I'm a person that understands detailed or simple directions, but I can not seem to find directions online. Now, I know what your thinking, but I've never attemped anything like this before. So, please, HELP! I need and want to learn as much as possible.
Thank you, tecfreak213
P.S. also, how do I change or get a web address? Thanks.

We've just started using AlwaysOn High Availability and run into a wierd issue. I have 1 particular database that is not syncing data to the secondary replica. But when i look at all the dashboards, everything is green, they all say synchronised - but if I query the data they are not.
The database has additional sql transactional 1 way replication a different server which i was wondering if was causing any problems, but it's working ok.
I'm just wondering if there's any other more detailed logs i can check to see why the data is not flowing. The availability dashboard and it's event log all says ok.

We are looking to setup an AlwaysOn A/G between two SQL instances across two SQL clusters - one cluster has two nodes the other has three nodes.
Is this possible using WSFC? Does the A/G wizard just handle this?

Hi -
I have tried several times to get started with SQL Server (I think I downloaded SQL Server 7 2005), but everytime I do there are so incredibly many steps to get started that I end up not going any further. This has been going on for longer than I wish to admit - but it is a very long time.
Isn't there some straightforward set of instructions that I can use to get started? What I want to do is to put some financial data in and then do some analysis of the data.

I have Enterprise version of SQL Server 2012 & SQL server 2008. I understand that Image/Text/NText is obsoleted and should not be used. That being said I dont understand why I couldnt rebuild the following clustered index, while I could with nonclustered index, this happens on both SQL 2008 and 2012. Here are the DDL.
CREATE TABLE [dbo].[Demo](
[ID] [int] NOT NULL,
[FK_ID] [uniqueidentifier] NOT NULL,
[SomeColumn] [nvarchar](100) NOT NULL,
[Image] [image] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
[code]...
An online operation cannot be performed for index 'IX1_Demo' because the index contains column 'Image' of data type text, ntext, image or FILESTREAM. For a non-clustered index, the column could be an include column of the index. For a clustered index, the column could be any column of the table. If DROP_EXISTING is used, the column could be part of a new or old index. The operation must be performed offline.
--Online rebuild works fine on non clustered index
ALTER INDEX IX2_Demo ON Demo REBUILD WITH(ONLINE = ON)--It seems to me that some how having the Image datatype column in the table is an issue. eventhough that column is not part of the index.

We use below OLA script to do our index maintenance and one of our previous engineer designed below script on web edition and I have a question of how online index rebuild works when we have web edition. Does the online Index rebuild really works? I am thinking it only reorganizes and does not do online index rebuild.
sqlcmd -E -S $(ESCAPE_SQUOTE(SRVR)) -d master -Q "
EXECUTE [dbo].[IndexOptimize] @Databases = 'DBName1',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE',
@FragmentationHigh = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE',
@FragmentationLevel1 = 5,
@FragmentationLevel2 = 30,

I am trying to build the 2 node 2 clusters with the AlwaysOn.
Here isthe landscape.
2 nodes PROD failover cluster (running once instance)
2 nodes DR failover cluster (running 2 instances - DR and PRE-PROD)
Both clusters are in different geographies.
PRE-PROD can be editable. So out of scope of Always On.
One instance on PROD -> DR of the other box. [Want to achive thru AlwaysON]
Now my Question:
1) Do i need to have all the 4 nodes in same failover cluster group? If yes, then this would become MultiSubnet cluster Or Is there any way those 2 diffrerent failover clusters (one DR and one PROD) can be part of AlwaysOn.
2) Can i use the clustered disks as in the above landscape for always on?

We have 2 SQL 2012 servers. Our application has 2 databases. We are creating an AlwaysOn cluster. Is it good to create 2 AlwaysOn clusters to have 1 database primary on one of the servers and the other database primary on the other server?
I have been asked if it is possible to have one database running on one server and the other database on the other server. Is this possible without creating 2 separate AlwaysOn clusters?

I have an A & B node set up and running. I now want to add a C NODE.
The catch is the C NODE is in a SQL Cluster Environment.
I am guessing I add the Virtual Name of the C node to the current Always ON Cluster?
I tried adding it...the error message says" the Virtual Node is really the A node and to add the A NODE"?

I was under impression that rebuilding index online largely means that the index will remain available for use during rebuild and my procs and query will be able to use it during rebuild. Also my understanding was that table will be locked very briefly while the schema change will be completing.But when I was rebuilding the clustered index online on a large table with some 3 million records, the table got locked and I was not able even to read the data from it for some 5 minutes. Then I cancelled the operation as it was production server and it was one of our main transaction table.
Is rebuilding index online supposed to work this way? The table has no other index.The parameteres I used are:
REBUILD WITH (PAD_INDEX = ON, SORT_IN_TEMPDB = ON, ONLINE = ON, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 95)

We have SQL cluster installed on top of windows cluster on VM environment. Node1 and Node2 under Windows Failover Cluster. SQL instance is currently on node2 the instance is up and running, but SQL Cluster service remains online pending and it restarts the instance on every 5 minutes.
SQL Browser service are running successfully.TCP/IP ports are enabled and configured.If we start the SQL server agent it is on for seconds and stopped immediately .Cluster Service is attempt to connect to the SQL service every few minutes (setting in SQL cluster resource) for the IsAlive check, if this fails then the SQL resource is restarted even if the instance was online. Hope this is what happening exactly.

Server1,Server2,Server3,Server4
Server1 is the Primary node and thr rest are secondaries. There is a Sync relation between Server1 and Server2 and also there is aSync relation between Server1 and Server3 & Server4.
Is it possible to setup log shipping from Server2 & Server3(secondaries) to two new servers?

How many nodes can you have in a cluster with SQL 2012 alwaysOn.
I understand that availability groups are limited to 5 nodes but if you had a 10 node cluster and decided to create multiple availability groups using various nodes within the 10 nodes but never exceeding 5, is that possible?
Or is there a counter or some validation from SQL AlwaysOn that actually hard limits to a grand total of 5 nodes in a cluster?

We had 3 Availability Groups set up in SQL 2012 last year but they were poorly named so I am just looking to rename them but there doesn't seem to be any command for it that I can find.Can they not be renamed once created? I guess I could just create new ones and move the DB's into them but just thought I would check!

Considering trying to move 2008 acitve/passive cluster with log ship to day old read only 2008 server to 2012 active/passive to 2012 AG Read only server. Only problem is that read only instance may have to be a 2nd instance on a server. The new box is a beast 64 core 256 gig of RAM hp so this is no dog. So I have these choices
migrate 2008 active/passive cluster to 2012 active passive (this will be it's own ordeal)take new monster box and build two instances, one that will run the AG read only database, the other will house reporitng services and analysis services and a few dw databases. We are not heavy into deep dive analysis services yet kind of in it's infancy. Not sure if this other instance will be sql 2008R2 , may be able to do 2012. MY also have a few small sharepoint databases but they barely use it.
