SQL 2012 :: Error At Adding Listener For AlwaysOn
Jun 11, 2015
I am trying to setup an AG on a cluster, I was able to define where I want my replica, but I need to setup the ip for the listener of that one
When I am adding the Ip at the listener I am getting the following message:
The Windows Server Failover Clustering (WSFC) resource control API returned error code 5057. 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.
The attempt to create the network name and IP address for the listener failed. The WSFC service may not be running or may be inaccessible in its current state, or the values provided for the network name and IP address may be incorrect. Check the state of the WSFC cluster and validate the network name and IP address with the network administrator. (Microsoft SQL Server, Error: 41009)
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....

When I fail an availability group between subnets, I am finding that the DNS entry in DNS is staying. So what happens is the Availablity Group listener has 2 records in DNS, one for each IP. This causes the App to timeout at times, since DNS will return either of the two IP's.

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 are rolling out the use of Availability Group listeners to our SQL Server 2012 Environment which has a 2 node multi-subnet cluster. The Primary is R/W and the Secondary is a non-readable node that would be manually failed over to in a DR scenario
I have set up the AGL and asked the sysadmins to create a DNS record in both subnets with fixed IP's.
The issue I have having is that when I ask the app developers to connect to the databases using the AGL it is totally random whether the AGL resolves to the Primary or DR node - as a result that are having problems getting their apps to connect.
I was thinking of asking the sys admins to remove the DNS record in the DR subnet and then add it back in should we need to fail over - but I was thinking there must be a better way.

Is it possible to ONLY allow a login to the availability group listener, but block logins to server instance/nodes?
So: MySQLServerA and MySQLServerB are in an avail group "MyAvailGroup".
I want users to login to MyAvailGroup's listener, but I do NOT want them to login to the actual hosts/nodes directly.
Is that possible?

I have MasterDataServices installed on a server and the database is in an AlwaysOn Availability Group.The MDM front end currently is set up incorrectly and is referencing NodeA (primary node) for its database.I want to fix this but im unsure if i should:
-point the MDM front end to the cluster name, so it wont matter what server the databsae is on?
-create an Availability Group Listner, which would also decoupple the database referenced from a particular server.

I am trying to build out an AlwaysOn AG with 2 nodes each in a different subnet (in AWS if that matters), windows 2012r2 / SQL 2014 RTM
I created a AG Listener with 2 ip address, 1 for each subnet (checked that neither ip address are used). But whenever i failover the AG to the secondary, and try and connect via the listener it fails,
I am trying to connect via SSMS from the primary instance. and just time out, If i roll over to the primary i can connect no issues, I've tried playing with the connection settings, upping the time out to 30 secs, adding the MultiSubnetFailover=true. etc but not getting any joy.

I have a two node HA Always on group using a Listener. I would like to force a certain AD group to always be forced to the secondry node as they would only ever need to run select statements. If there an easy way to do this without using logon triggers?

I'm getting an error adding Replica to SQL AlwaysOn failover cluster in the new availability group wizard. When I enter the name of the target node (secondary replica) server and press connect, I get the following:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2) The system cannot fine the file specified
The SQL Browser service is up and running on the target. I am using an Azure VM for my SQL instance. This cluster spans geographies from our on-premise site to Azure via a VPN. This is a multi-subnet cluster. I'm attempting to create a new AG from the primary replica node and the target is a node on Azure called SSASNodeAz03.

I ran into a Kerberos authentication issue because of a missing AOAG SPN. Some of the tickets that granted me access to the nodes of the AOAG cluster were using the encryption type that I would expect. However, the MSSQLSvc SPNs were not using what I would expect!
klist
#XX> Client Somebody@somedomain.com
Server: RPCSS/MySQLServer@somedomain.com
KerbTicket Encryption Type: AES-256-CTS-HMAC-SHA1-96
#XX> Client Somebody@somedomain.com
Server: MSSQLSvc/MySQLServer@somedomain.com
KerbTicket Encryption Type: RSADSI RC4-HMAC(NT)
#XX> Client Somebody@somedomain.com
Server: MSSQLSvc/MyAOAGListener@somedomain.com
KerbTicket Encryption Type: RSADSI RC4-HMAC(NT)
I can't seem to figure out what the next step should be, and the infrastructure admins are stumped as well. How to proceed?

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):

I have an issue when connecting with application Intent=readonly when using Listener name. I can connect to the read only secondary with application Intent=readonly if I use the server name. It gives a host does not exist error when using listener. This happens only if I am using the application Intent keyword. I can connect for normal readwrite operation using listener name.

I have set up a couple of servers in a SQL 2012 AlwaysOn Availability Group (non FCI). I have also configured a Listener which enables SQL clients to connect to the server currently servicing the database, as expected.
I would also like non SQL clients to be able to connect to the server currently hosting the database so that they can run scripts sitting in a share. I don't have a shared disk so just have a directory share on each server with the same scripts in each directory.
I am able to ping and RDP to the listener IP address/name and end up on the correct server but am unable to connect to the share ListenerNameShare. Is that actually supported? If it is, any thoughts on what I need to do to get it going. If it isn't what other options do I have?

We have a multi-site AG and are demoting one of the remote sites out of the AG. In doing so, we've discovered that no logic exists to remove an IP address from the listener.
It seems that the ALTER AVAILABILITY GROUP MODIFY LISTENER logic lacks functionality other than ADD. [URL] ....
I'm afraid to just remove the IP address from the cluster object as that IP is also stored in the HADR systables.

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?

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?

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"?

We have 4 Servers which have SQL SERVER 2012 and "AlwaysOn" have been enabled on all 4 servers:
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.

In 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.
