We have a server A and a server B setup with SQL2014 High Availability - working fine.
I need to add an additional listener to our new DR site (SQLNODECOLO).
What is the best way to do this without impacting production?
Can I just go to server A and add the new listener server here (SQLNODECOLO):
why my listener has two dns entries? Shouldn't it only have the active node's address? I have the cluster RegisterAllProvidersIP set to 0. We have two synchronous local sql 2012 servers on windows 2012 r2 and one remote (different subnet) asynchronous node. Is it safe to manually delete the dns record that's pointing to our remote listener? Why did it add both of them?

I have configured two networks, one for heartbeat and second for public.My question is do I need a third network/ subnet for AG Listener? Which network does the SQL user databases in the AG group use to replicate between the replica servers?When I do the SQL backups, do I need to backup primary and secondary replicas or just backup the databases in the secondary replica?
View 4 Replies View RelatedAfter manual AG fail-over from primary to secondary the application is not able to connect the listener name for atleast for 5 - 10 mins
The telnet fails during this time from app server, the listener ip is on muti-subnet.
At the same when i try to connect it from SSMS from a remote machine it works fine.
I am not able to connect listener after manual failover.
(This is test environment)
Server1,Server3 -> Both synchronous (Within Same data center)
Server 3 -> Async (At DR location) -Forced Failover
Test1:
Failover Server1 to Server2 --> Able to connect Listener
Failover Server2 to Server1--> Able to connect Listener.
Failover Server1 to Server3--> Able to connect Listener.
Failover Server3 to Server1 or 2 --> Unable to connect Listener. Unable to ping Listener.
Failover Server 1or2 to Server3--> Able to connect Listener.
I am using below sub-nets:
10.11.192.0/22 10.11.192.130
10.12.192.0/22 10.12.192.140
In our(my company) current design we want to switch from failover clustering to Always On as high availibility solution.
I am currently testing the availiblity Group Listener function and have two questions regarding this.
First of all, is it possible to connect to a a listener by just using its "name" instead of "name,port", it is for our users very inconvenient to start using ports. If this is possible, where can I find information on how to configure this?
Second, is it possible to use the Availiblity Group Listener as loadbalancer or in combination with a loadbalancer to split the users over two or more nodes?*note we don't use azure.
Assuming all windows servers belonging to the WSFC are on the same subnet, will the AG listener become a single failure point in system if all Application servers connect to the AG through the listener? If the answer is yes, what are the options to resolve this issue?
View 3 Replies View RelatedWe are trying to build HA and DR environment, combining AG and FCI. So we have 3 servers added to a cluster, 2 of them sharing the same storage and working as ACTIVE-PASSIVE cluster instance. The other server has a stand alone instance with its local storage, with the same drivers letters as the cluster instance.
Between the Active FCI and the Stand Alone, we set up an Availability Group. They are running fine, except by the listener. When the stand alone instance owns the Primary Replica, I am able to access the SQL Server instance by the listener, but when the Primary Replica is owned by the FCI, I can't reach the database by the listener (name or IP).
I've opened the same ports in both servers, it hasn't worked though.
I think theres something I'm missing about AG listeners. My test config is 1 SharePoint WFE & 2 SQL servers configured in an AAG.WFE, SQL1 & SQL2 servers are all on the same subnet.On the WFE, I configured an alias called SP15 to be used for the SQL servers. If I failover from SQL1 to SQL2 I just need to change where the alias is pointing on the WFE. So why do I need a listener? This works fine, albeit manually.I have read on some posts that an automatic failover process is possible. How can I add a 2nd IP address to the listener when both SQL servers are on the same subnet? The GUI doesn't seem to allow this.

View 6 Replies View RelatedI am setting up a new pair of SQL 2014 enterprise servers in HA using Availability Groups. One of the servers is located here in our local datacenter (10.0.1.x) and the other SQL server is in our remote datacenter(172.16.1.x). I was able to setup the Windows Failover Custer without much issue. I setup the AG but when I try to setup the listener. I get the following error. I have setup an IP for both networks on the listener. I have confirmed that there is not any DNS records created for AG listener name. But I still get this error.

When I am adding the Ip at the listener I am getting the following message:

The WSFC service may not be running or may not be accessible in its current state, or the specified arguments are invalid. For information about this error code, see "System Error Codes" in the Windows Development documentation.

Browsing around I found this guide: [URL] ......
And I make sure that the cluster has permissions to "Read all properties", "Create Computer Objects", even to "Create all child" permissions
I also added those permissions to the account that starts sql at that cluster and I am logged as that and I am still getting the error....
Hi,
What are all the performance parameters to be analyzed, in an existing production server, to accommodate an additional database.

Hi All,
I have developed a report using report viewer in asp.net web form. The report is generated based on the selection of Department. User have an option to multi select the departments so the department column grows. Lets say user select Business category first and generate the report then user decides to add another department say Engineering. No the report column headers will have addional column "Engineering". I have used the Matrix since I had to group by Name and dates. Everything is good so far.
Now I have to add an additional column "Notes" at the end of all the columns. If there is ony department is chosen then Notes column appears after that and if mulitple departments are chosen the Notes column should also appear after all the department column (at the very end).
I am really having hard time to accomplish this. Is there any suggestion or solution to finish this? I really appreciate your responses.
Thank you.
Environment: SQL Server 2014 on Windows Server 2012 R2.
We have our availability group configured and working. However, when we try to connect to the AG listener from a remote server, we have to use the fully qualified domain name (FQDN) to connect. We'd like to be able to connect just using the host name. Interestingly, ping actually resolves the IP correctly for either.
I have getting issues when i am creating listener for always On . Error shown as below
Can not bring the Windows server fail over cluster (WSFC) resources online. (Error Code 5942). The WSFC service may not be running or may not be accessible in its currents states, or the WSFC resources may not be in a state that could accept the request.

I am using an execute SQL Task item on the control flow to be used as input for the foreach loop container. I have a select statement but, based on other information provided before this is executed, additional 'and' information may need to be added onto the SQL Statement before execution. For example, the select statement may read:
select applicatonid, created, createdby
from application
where referred by = 'xxx'
But based on information obtained from an ini file, something like:
and referred date = '2008/05/28'
may need to be appended to the SQL statement. I have tried setting the SQL statement as:
select applicatonid, created, createdby
from application
where referred by = 'xxx'
+ @addlwhere
and defined the @addlwhere in the parameter mapping but it raises an error. Has anyone run across this type of need and how did you resolve it? Thanks!
Hi,
I want to setup disaster recovery site for small databases from disffrent data centre.Which method would be good and from where I will get some good stuffs to read except online documents?
I have setup a WSFC that contains 3 nodes ( node 1,2 belongs to subnet A and node3 to subnet B), lets say node 1 is the primary host in the wsfc.
Each node has their own sql server instance, that i configure an Availability Group that will replicate between node1 and node 3), created an Availability Group Listener that will contain 2 vips for each subnet.
My question here and I am not sure if i missed something when setting up the Availability Group. If i failover an Availability group from sql server from node 1 subnet a to nde 3 subnet b, then the listener will be on the vip that belongs to subnet b and the primary instance will be the one in node 3, but this wont cause the WSFC to move the primary host from node 1 to node 3.
So at this point dont see what is the dependency between setting up the AG with WSFC. when fail over an AG doesn't cause the primary host in wsfc to fail over as well.
Why availability group relies on WSFC and how can i make it to depend so the primary host moves as well?

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.
We have two locations in US, I am thinking of having 2 node SQL cluster for Lync 2010, I alardy have One DB server running in one location, now we got new site where we are planning to have one more DB for redundancy.

Sorry for the wide distribution.
I'm trying to find any useful whitepapers about how to effectively build and operate a disaster recovery site at a remote location for SQL Server 2000. Does anyone know where to find such information?
I also know that one good option for my customer is using the Mirroring feature of SQL Server 2005. What are the other options? Is Replication an effective one for a mission-critical database (online banking)?
Thanks in advance
I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?
We have an AAG environment. In order for the failover to be transparent we have to ensure that the login that is added in the Primary node is also added to the secondary node. Currently, we are adding the logins to the secondary node manually. Is there a way to automate this process so that a Login added to the Primary node is automatically updated on the Secondary Node.
View 4 Replies View RelatedI am in the process of rolling out a pair of SQL 2014 servers. I have setup an Availability Group, Listener and databases. It's my understanding that I will be giving the listener name to our developers so that they can do their work. In testing, I noticed that If I am using Studio Manager and connected to the the AG using the listener name, when I setup a user in security the user is only added to the active primary node. Is there a way to add a user to both servers in one shot instead of having to install on both servers?

One of my actual production environments is a Failover two-node cluster, SQL Server 2005 SP3 on Windows Server 2003 R2. Recently, the node 2 was failed, so I formatted a new machine to add the new node, but it failed with the following error: “Adding nodes to the Virtual Server definition using a newer version of Setup is not allowed.”I have searching across the web for a solution but I can’t find it.
The Summary file “Summary.txt” are:
Microsoft SQL Server 2005 9.00.1399.06
OS Version : Microsoft Windows Server 2003 family, Enterprise Edition Service Pack 2 (Build 3790)
Time
: Thu Jun 04 13:04:38 2015
[code]....
One point of my attention, it’s that the Product Version that appears on this summary file corresponding a 9.00.1399.06 that is to say, a RTM version, not SP3 (9.00.4035).Based on this, I went to the path where the files of installation are (ARPWrapper.exe), "C:Program FilesMicrosoft SQL Server90Setup Bootstrap"and I 've found that these files contain a different version of what I have currently installed. For example, in properties of ARPWrapper.exe the version of this is 2005.90.1399.0 The same goes for the rest of the files in that folder:
Microsoft.SqlServer.AnalysisServices.UpgradeAdvisor.dll
Microsoft.SqlServer.BestPracticesAnalyzer.UpgradeAdvisor.dll
Microsoft.SqlServer.DTS.UpgradeAdvisor.dll
setup.exe
Is it possible that the solution is to replace these files with the corresponding version, in this case the version 2005.90.4035.0(SP3) and continue with the installation?
We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.
