SQL 2012 :: Log Shipping - Reboot Secondary Node And Then Primary Node
Apr 20, 2015
I have not used log shipping before and find myself in a position where I need to reboot the secondary node and then the primary node and I don't actually need to failover.
Is there anything I need to be aware of. When rebooting the secondary node I assume the transactions will be held in the primary nodes log till the secondary comes back and just carry on once back up?
When rebooting the primary node nothing needs to be done and the log shipping will just start again once it has come back?

I have a SP that runs on the primary in 18 min and 45 min on the secondary( poorly written cursor,trying to fix it).Both machines are Exactly the same.I ran them in the middle of the night when no one was on the Sec. Node as we use it for reporting.
PLE: 7,000+
AVG Disk sec/write below .01
AVG Disk sec/read below .01
CPU below 5%
both machines set a max dop 4

I have created a Test SSIS Package within BIDS (VS 2K8, v 9.0.30729.4462 QFE; .NET v 3.5 SP1) that connects to our Test Listener.
There is only 1 Connection Manager Object, and OLE DB Provider for SQL Server.
The ConnectionString lists: Provider=SQLOLEDB.1;Integrated Security=SSPI
The Test Connection within BIDS works.
The Package Control Flow has just 1 Object, and Execute SQL Task that performs an Exec on an SP that contains only a Select (Read).
The Package runs within BIDS.
I've placed this Package within a Job on the Primary Node. Ive run the job successfully using 32 bit runtime on and off. The location of the file on the server happens to be on a share that resides on what is currently the Secondary Node.
When I try to run the exact copy of this Job on the Secondary Node (Which has been Set up for Read All Connections; Yes), I get an error, regardless of the 32 bit runtime opiton. At this point, the location of the file is on the Secondary Node.
The Error is: "Login failed for user 'OurDomainAgent_Account'".
The Agent is a member of NT ServiceSQLServerAgent on both instances, and that account is a member of SysAdmin. Adding the Agent account as well, and giving that account SysAdmin, makes no difference either.
Why can't I get this to work?

I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.

We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).
As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.
However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.

During the installation of the SSISDB in SQL 2012 AG, the password used to encrypt the database was not preserved. Now when the server is failed over, the SSISDB on the new primary node is not use-able.Document the password and decrypt after using the master key after failover.

y'day we faced situation one of the primary server went down and unable to failover the services to second node . by checking in logs we found
Cluster network 'Public' is partitioned. Some attached failover cluster nodes cannot communicate with each other over the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

I have a scenario where a customer is going to be using Log Shipping to the DR site; however, we need to maintain the normal backup strategy on the current system. (i.e. Nightly Full, Every 6 Hour Differential and Hourly Transaction Log backup)I know how to setup Transaction Log Shipping and Fail-over to DR and backup but now the local backup strategy is going to be an issue. I use the [URL] .... maintenance solution currently.
Is it even possible to do regular backups locally keeping data integrity for your backup strategy with Transaction Log Shipping enabled?

Currently in my environment we are using SQL server 2012.We setup Alwayson with synchronous commit.Details of existing AlwaysOn: one primary and two secondary.
Primary: On-Premise server.
Secondary1: On-Premise server.
Secondary2: Azure VM.
Requirement: We need to add Secondary3 New Azure VM on same AG with asynchronous mode or synchronous mode.
Or
We need to create one more AG on same DB and add the new replica with asynchronous.Is it possible above 2 option in this scenario? My cluster environment is Manual failover only not auto failover.

I read these instructions:
http://msdn2.microsoft.com/en-us/library/ms191545(SQL.90).aspx
But I'm not sure if I have to install SQL Server first on node 2, then add it to the cluster. Or does adding it to the cluster also install the software?
Thanks

Server : Windows server 2008
DB Server : SQL Server 2008 (SP1)
Here are the series of events which happened.
1.) Event ID: 1135
Cluster node 'XYZ' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
2.) Event ID: 1049
Cluster IP address resource 'SQL IP Address 1 (XYZ)' cannot be brought online because a duplicate IP address '10.9.8.113' was detected on the network. Please ensure all IP addresses are unique.
3.) Event ID: 1069
Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
4.) Event ID: 1049
Cluster IP address resource 'Cluster IP Address' cannot be brought online because a duplicate IP address '10.9.8.112' was detected on the network. Please ensure all IP addresses are unique.
5.) Event ID: 1069
Cluster resource 'Cluster IP Address' in clustered service or application 'Cluster Group' failed.
6.) Event ID: 1066
Cluster disk resource 'Cluster Disk 25' indicates corruption for volume '?Volume{88552e6f-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 25_Disk16Part1.log'. Chkdsk may also write information to the Application Event Log.
7.) Event ID : 1066
Cluster disk resource 'Cluster Disk 26' indicates corruption for volume '?Volume{88552e05-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk
output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 26_Disk4Part1.log'. Chkdsk may also write information to the Application Event Log.
8.) Event ID: 1049
(Same message as point 2)
9.) Event ID: 1069
(Same message as point 3)
10.) Event ID : 1049
(same message as point 4)
11.) Event ID :1069
(same message as point 5)
12.) Event ID :1205
The Cluster service failed to bring clustered service or application 'Cluster Group' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
13.) Event ID: 1069
Cluster resource 'Cluster Disk 17' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
14.) Event D : 1049
(same message as point 2)
15.) Event ID: 1069
Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
16.) Event ID : 1205
The Cluster service failed to bring clustered service or application 'SQL Server (MSSQLSERVER)' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
first of all,I went through all the logs, and could not find the reason for fail-over initialization. There should be some thing logged why the failover happened? secondly after failover the service was not coming online due to duplicate IP address detection.
Later when we try to manually bring the service online from cluster management it comes online successfully. I don't understand how would duplicate IP address get resolved when we start manually.
Lastly we see few errors related to physical disk resource between failover retries, is this could be the correlated to failover error ?

I configure Windows 2003 R2 and SQL 2005 two nodes Cluster. When I move cluster resource from one node to anther node it takes around 30 seconds to become online. So in that time if any query is running it stops responding.
So please suggest in this regard

I invoke xp_cmdshell proc from inside a stored procedure on a 2-node active/passive SQL 2005 SP2 Standard cluster. Depending on which server the xp_cmdshell gets executed on I need to pass different arguments in the shell command. I thought I could use host_name() function to get the runtime process server, however, I am finding that it's not behaving correctly. In one example I know my active node is server2, but the host_name() function is returning server1. The only thing that I could possible explain this is that the MSDTC cluster group is not always on the same active node as the SQL server group and in the case I am talking about the cluster groups are in this mode (differnet nodes). Does the xp_cmdshell get executed by the SQL active node or the MDTC active node? And what is the best way to find out which server is going to run my xp_cmdshell?
Thanks.
Edit:
Perhaps another by product of this is that if I run select host_name() from the Studio Management query window i get different results depending on which server I am running the Studio Management on. On server1 I get server1 and on server 2 I get server 2, all the while server2 is the active node. I need a different function that will always let me determine the correct server that'll be running the xp_cmdshell...
Edit 2: I guess I could determine the running host inside the command shell itself, but I am curious to see if i can do it (cleaner) from SQL.

I 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.

I have a table which has a field with a data type of Xml. A sample record might contain something like this:
<?xml version="1.0" encoding="utf-16"?>
<order>

<Attribute Name="Paper" OptCatId="1" Value="72" ....../>
<Attribute Name="Ink" OptCatId="2" Value="6" ......../>
<Attribute Name="Bleed" OptCatId="3" Value="15" ......./>
<Attribute Name="Number of Drops" OptCatId="0" Value="1" ...../>
I need to grab the Node/Attribute with the name of "Number of Drops" and get the value of "Value". So in this case, I simply want to get "1". How could I do this?
SELECT "value of Number of Drops"
FROM myTable

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 are running SQL Server 2012 Enterprise on Windows 2012 R2. We have set up A WSFC with the primary Node in our East Coast Data Center and the Secondary Node in our West Coast Data Center each node is in a dfferent subnet. Since we have high latency between the sites we run in Asynchronous mode with manual failover only. My quesion concerns Quorum, everything I read would indicate we need a third node (odd number) (e.g. a fileshare Witness) with only the file share and the primary node having a vote...What I don't see is any need for a file share if we can only do manual failover.

What I have- Sql server 2012 (Standard Ed) Cluster on Windows 2012 R2 with both instances running on the same node- just to save on License, i.e. technically it’s Act/Pas cluster.
What I am looking for- how to configure cluster (e.g. via quorum, etc) to force both instances failed together? Means if for some reason 1-st instance will fail to node 2 another instance should follow (otherwise it will be Act/Act cluster and 2-nd license is required).
If there is no standard way (cluster configuration I mean) to do it I should create some custom process to monitor where each instance is running.

I have configured Alwayson HA setup as following environment and versions, and working fine to client side by connected with AG Listener.
Two Node WSFC setup. Node1 (Primary), Node 2(Secondary Replica). Normal quorum(Not shared disk)
Server Platform: HyperV
OS: Windows server 2008 R2 64 bit with SP1
RDBMS: MS SQLSERVER 2012 64 bit with SP2
when I am doing testing Failover method between two nodes. automatic failover not happened.
Just shutdown Node1 and try to connect at client side by using AG Listener name but not succeeded, also Cluster name and AG Listener name are not pinging, Second node2 cluster service is not started by automatically due to as below errors. So how will connect client and overcome this issues? Any modification need to be done on both side WSFC and AlwaysOn SQL? for achieving and automatic failover.
Cluster network 'Cluster Network 1' is partitioned. Some attached failover cluster nodes cannot communicate with each other over the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
Client side got connected once Node1 get started again also cluster services started.

Our network guys have to carry out an IBM Flex Chassis move at our data centre, which will affect the primary replica of one of our SQL 2012 AlwaysOn Availability Group nodes (the secondary replica won't be affected).
They have suggested using vMotion to migrate the primary replica to another virtual host, which will result in a very brief period of network outage for the node.
I've done some reading and have seen a few potential issues regarding Stun During Page Send (SDPS) and increasing thresholds within WSFC. Unfortunately, we're not able to test this prior to the migration, so I have a few questions...
Would it be necessary to failover to the secondary replica node before performing the vMotion (and back again afterwards)?

Few questions on a SQL Server 2012 two node active/passive cluster installation on Win2012.
1. What are the permissions required for the user used to install SQL Server 2012 cluster. Does it need to have any rights on DC or anywhere else apart from the local nodes ?
2. Can we give ANY meaningful name to "SQL Server Network Name" during installation ? Do we need to manually configure it anywhere else before or after the installation ?
3. On what scenarios we need to check/uncheck DHCP check box ?

I have a tree and I need to copy a nested sub-tree (an element with its children, which in turn may have their owns) from one place to another.
The system should allow to handle up to 8 levels. I do know how to move, but cannot figure out how to copy.
Below is a working example With Create Table, Select and Cut / Paste (implemented via Update).
I would like to know how to copy a nested tree with reference id 4451 from Parent_Id 1 to Parent_Id = 2
--***** Table Definition With Insert Into to provide some basic data ****
IF (OBJECT_ID ('myRefTable', 'U') IS NOT NULL)
DROP TABLE myRefTable;

It is an active passive cluster which doesn’t allow any testing. All instances have to be failed over together, we aren’t allowed to just failover 1 even for testing purposes. Node 1 is the active node and we can failover to node 2 for 30 days free of charge but services have to then be failed back.
We need to run the cluster with node 1 as the primary node always and 2 just use for failover testing or for less than 30 day periods whilst performing cluster patch upgrades etc.
Now l am sure we could fail over 1 instances at a time for testing and diagnosing issues plus if add a new instance that's not production to get to the platform level as the rest of the instances this would avoid taking production down in the fail over process.

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.
