How do I reliably symmetrically encrypt a single node in an XML field in my SQL Server 2012 database? I know I cannot use SQL Server encryption to encrypt an XML field and I have been getting unpredictable results with a home grown solution.

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'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.
View 1 Replies View RelatedWe 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.
Does some know of an easy to understand way to encrypt a single table column? I have never worked with encryption before.

hello guys! i have a question hope you'll help me..how can i encrypt the data that is stored in my password field everytime i insert value to it and decrypt it if i want to retrieve it? thanks in advance!!
View 7 Replies View RelatedHello,While working through my encryption questions from preivous posts, I amfinding that I may have to resort to use triggers to do the encryption(not that this is the only way, but might be the best way for mycircumstances).I would like to create a trigger that will encrypt the field before thewrite is committed.I've found serveral posts about triggers, but nothing that fits what Iwish to do.Upon an insert or update I want to modify the ssn field with this:cast(EncryptByAsymKey(AsymKey_ID('Student_aKey'), cast(SSN asnvarchar(11))) as nvarchar(40))so, ssn '123456789' in SSN would become <something encrypted> in SSNThis is the trigger I have so far, but it is generating an error:CREATE TRIGGER F_Student_SSN.eSSNON F_STUDENT_SSNINSERT, UPDATEAS SELECT cast(EncryptByAsymKey(AsymKey_ID('Student_aKey'), cast(SSN asnvarchar(11))) as nvarchar(40))TIARob

I dont know how to do it in SQL server 2000.
Please help me on this. Its urgent.
Thanks and Regards
I understood that sql 2005 has EncryptByCert(varchar) function to encrypt data field. but varchar is limit by 8,000 chars long.

I have following data in my table. In some of the elements there can be missing nodes. I need to find out missing nodes from each element and insert default node if it doesnt exist so it validates with schena.from below exmaple in the third element location node is missing and i would like to add default node if we see any of these.
Input
CREATE
TABLE #t (xmlfile
XML)
INSERT
INTO #t
[code]....
Some times Location tag name can be Location10. like <Location10>NY</Location10>.In this case i need to update <Location10> to <Location> to validate with XML schema.
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>
<Product Index="14c9643f-63d9-40c5" ProductID="13" Name="............>
<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
WHERE ID = ....
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"?
Can I add a new node to an existing sql server 2012 cluster witthout stopping all the current resources?
Currently, there are 2 nodes and 3 sql server instances, which can not be shutdown. Is the process of adding nodes a "online" process?

I have installed SQL Server 2012 on Node1 successfully and trying add node on Node2 and its failing with below message. I attached the screen shot.

I am trying to extract what I believe is called a Node from a column in a table that contains XML. What's the best way to do this? It is pretty straightforward since I'm not even looking to include a WHERE clause.
What I have so far is:

FROM tblCCH AS CCH
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.

View 5 Replies View RelatedWhat 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)?
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.

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;
GO
CREATE TABLE myRefTable
(
Reference_Id INT DEFAULT 0 NOT NULL CONSTRAINT myRefTable_PK PRIMARY KEY,
[Code] ....
How to Copy nested sub-tree 4451 with all its children to Parent_Id 2, without deleting from Parent_Id = 1 ?
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.
