How Do I Clean Up The SQL Server (ctp) From ADD/REMOVE Program Without The Change/remove Button
Oct 12, 2006I have uninstalled the CTP version of the SQL Server express so that I can install the released version but CTP version is still listed in the add/remove program list but without the change/remove button. I have been to different sites to find information on cleaning this up and I have ran all the uninstall tool I can find but the problem still prevails. I cannot install the released version without completely getting rid of the CTP version. Please help anyone.

May 13, 2013I'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?

Mar 13, 2014I 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?
SQL 2012 :: Creating 2 AlwaysOn Clusters For 1 App
Apr 11, 2014We 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?

SQL 2012 :: AlwaysON Setting Up A C Node?
Apr 28, 2014I 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"?

Jun 7, 2015I Config Ha-Alwayson on 2 test servers . In addition, was defined a listener for them.i can connect to them from the listener and in directly. I did manual Failover and it worked.However all connection to all servers (primary and secondary and listener) was breaked. I expected my connection To The listener, be stable. But How can I test the Auto failover mechanism? I run this scenario :
1- I filled all free space from the primary server else a bit.
2- And run on it a Huge Update to fill remain free space.
3- MeanWhile I Run an insert command into listener IP. (in a while Loop)
I expected :
>>> After run update or in middle of it , The primary server face to a problem. (Full Log file). And This was happened.
>>> After I expected The Failover act and change Primary And Secondary.And My insert commands Continues without Break Or Continue On new server After some Seconds
But It didn't Happend.Both Of 2 Command are stoped !!!!! And auto failover didnt act. I tryed To create a manual fail on primary server . I Tried to Offline the main database in primary server.
Then
1- What is the meaning Of fail that Auto failover act about it ?
2- In which scenario I can Test It ?

Aug 6, 2015We 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.

SQL 2012 :: Maximum Cluster Nodes In AlwaysOn
Mar 17, 2014How 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?

Jul 18, 2014Considering 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.
SQL 2012 :: AlwaysOn - Readable Secondary Option
Aug 21, 2014In always on under availability group server name properties can see the option Readable Secondary. In that for secondary server the Readable Secondary Option is YES and for Primary it is Read-Intent. I believe Read-Intent allows only read only connections and YES allows all user connections.

SQL 2012 :: AlwaysOn AG Replicating Much Slower Than Mirroring
Sep 30, 2014I'm setting up AG replication over our WAN (1GB MPLS). Using sql stress, AG replication quickly falls behind. Network throughput plateaus at ~14Mbs.
The problem ISN'T NETWORK
using conventional mirroring, the same workload never falls behind, throughput plateaus at ~26Mbs.
it's almost like log stream compression isn't happening for AG...
both mirroring and AG are using async.

View 3 Replies View RelatedSQL 2012 :: AlwaysOn Failover Due To Missed Heartbeats
Dec 10, 2014I have setup SQL AlwaysOn between primary and DR data centers. Here is the setup:
Primary data center: Server1 (Primary), Server2 (Sync Commit Secondary), Server3 (ASync Commit Secondary)
DR data center: Server4 (ASync Commit Secondary)
Data synchronization and manual failover works fine. But, sometimes, the AlwaysOn cluster automatically fails over to Sync Commit Secondary on Primary data center. Here is the error message from Failover Cluster Manager->Cluster Events:
"Cluster has missed two consecutive heartbeats for the local endpoint xx.xx.xx.yy:~3343~ connected to remote endpoint xx.xx.xx.zz:~3343~"
"Cluster has lost the UDP connection from local endpoint xx.xx.xx.yy:~3343~ connected to remote endpoint xx.xx.xx.zz:~3343~"
I had our network engineer check all connections multiple times and he confirmed everything is fine. But he was also able to confirm (using monitoring tools) that right at the time of a failover, there is almost 2GB worth of traffic going from Primary Server to DR server. That happens every time. I had checked the times of all failovers and there is no job or process occuring that will produce 2GB worth of data. Also, this happens regardless of which server is primary.
Even though the failover works fine, this unexpected automatic failover due to missed heartbeats are occurring often (2-3 times a month).
Here is the list of errors from the Cluster Validation Report:
Under Network Section, I see the following error messages in Red:
Validate Network Communication
Network interfaces Server4 (DR) - SAN_Team and Server1 (Primary) - SAN_Team - VLAN 20 are on the same cluster network, yet address xx.xx.xx.pp is not reachable from xx.xx.xx.yy using UDP on port 3343.
Network interfaces Server4 (DR) - SAN_Team and Server2 (Secondary) - SAN_Team - VLAN 20 are on the same cluster network, yet address xx.xx.xx.qq is not reachable from xx.xx.xx.yy using UDP on port 3343.

Jan 27, 2015So I have 2 servers S1 & S2.
Database Group 1 = L1 with Primary S1 and Secondary S2
Database Group 2 = L2 with Primary S2 and Secondary S1
For 99% of the time the 2 groups of databases are not related. For the 1 procedure that does move data from L1 to L2 something like
Update L2.DB.Owner.Table
set flag = 1
Whare a = 0
On S1 I have a linkedServer with connection to L2.
If I have a failover I cannot have L2 on S2 as they are essentially the same server.

AlwaysOn Connection With Primary Node Using Its Host Name
Feb 26, 2015I have set up a 2 node availability group to take advantage of using the secondary node for a read-only replica. I actually am having two issues. The first being I can connect to the primary node using the listener dns name and ip address, but no longer can connect via its actual host name or ip address. I can ping the address with no problem, but I can't connect to port 1433 using the actual host name or ip address.
I am no problem connecting to the secondary node using its host name, but can not get to it through the listener using the applicationintent=readonly. Eventually I would like for everything to connect through the listener name, but for now still need to connect via the server's host name and don't understand why; everything I read is that the primary node should be able to be connected via both the host name and the listener name.
SQL 2012 :: Log Management Of Primary Database In AlwaysOn?
