I was able to do windows cluster successfully on vmware but after destroying it and I wanted to rebuild cluster on same nodes with same vmnode as DC.But Clustering kept failing.... and I had to rebuild entire vmnodes ,ISCSI SAN and Clustering from scratch...
How do I get over this problem.I want to manage cluster so it remains stable after failover or even after shut down of VMnodes????
I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?
View 6 Replies View RelatedWe have set up SQL server 2012 alwaysOn availability group on windows 2012. It runs and fails over successfully. Recently, a VMWare creates a snapshort of a primary and it breaks a cluster. We saw errors in a cluster log.
In VMware setting, The quiesce option is turned off for these VMs. Also, we configured cluster setting :Windowssystem32> (get-cluster).SamesubnetThreshold = 10 ( Relaxed )
Cluster node 'Test1' 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
File share witness resource 'File Share Witness' failed to arbitrate for the file share 'TestTEstQuorum'. ensure that file share 'TestTestQuorum' exists and is accessible by the cluster.In alwaysOn error log, A connection timeout has occurred on a previously established connection to availability replica 'Test1' with id [CAD40D99-E333-457E-9993-BBE977D2CDA2]. Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.
I know now that AlwaysOn feature HAS to be installed/configured on a Windows Clustering environment, BUT the secondary replicas, like the Disaster recovery replica residing in a different Data Center HAS to be also in a Windows Clustering environment or can it reside on a SINGLE SQL Server INSTANCE?.
View 6 Replies View Relatedcan we join a node in a windows cluster which is already in a different cluster?
We have this requirement as we need to setup readable secondary ( always on AG) on the third node.
We are planning to change all IPs of PRODUCTION Failover Cluster Setup. In my cluster setup ... we have 2 Physical Nodes with windows-2008, Roles are MSDTC and SQL-2008R2.
IP change for:
1. Both Nodes(Physical)
2. MSDTC
3. SQL Server
4. windows Cluster
So Almost... All IPs are going to change.
Im DBA here, I need to take care of SQL cluster and MSDTC. But I haven't performed this activity before.So I'm worrying about Impacts and consequences of this change. steps how should I perform this activity.
Looking at the recovery model on MSDN - was under the belief from it that if you set your database to use the simple recovery model, then when you preform a full back up it would truncate the transaction log file but this doesn't seem to be the case?We aren't looking to do a point in time recovery for this particular databse.

Logging out of application and log back in ( connecting to a new database session) did not clear the buffer cache as I thought it would.. When does the database clear the buffer cache? Is it not per database session?
I can issue CHECKPOINT and then run DBCC DROPCLEANBUFFERS to clear the buffers in the disk. But since we are testing from the application,do we need to run these commands via application code to clear buffer/per database session OR can we run these commands from a management studio session?
I ran the Advanced cluster preparation for a new sql instance on an existing cluster.

Hi all,
I'm about to install SQL 2000 SP4 on a Windows cluster and I was wondering if there is anything to look for in particular. I went through the readme.txt and microsoft has one aticle but I was hoping to find out a little more.
Thanks all
Seb.
I have a strong Oracle background but I am new to the SQLServer world so please forgive me for my ignorance.
In Oracle you can "destroy" an index if you use ceartian functions on that indexed column in the join criteria. Is this the case with SQLServer, if so can someone supply me a list of index destroyers?
Thanks for you help in advance!

I installed MS SQL 2000 on a Windows 2003 server cluster (no servicepacks). Both nodes are online and both domain controllers are online.I tried to install SP3 and got the following error:--------------Logon Account could not be validated.No authority could be contacted for authentication.---------------I installed SQL SP 2 and did not get the error but I do get it everytime I try to install SP3.Does anybody have an idea that might help resolve the problem.

Good morning all!
I've created a a new column on a table:
CD_Line int identity
This ADD COLUMN command gave me an error on this morning, we're talking about 40 million rows on this table.
The ROLLBACK TRAN is destroying my system that can't login on the SQL Server and no application can by Database at this moment.
Do anybody know how to STOP this situation and recovery the system?
Tks!

View 9 Replies View RelatedHi all
I am busy looking at the WIndows 2003 Comptu Cluster setup (Well I am loading it)
And I am interested to know if any body has run SQL 2005 Enterprise on this platform before ?
I know that Windows Compute Cluster uses a JOB scheduler to run tasks and this can be customised for each task , to allow it to use more resourses or less .
I also know that SQL 2005 is much more capable of running cluster mode with database replication and log file shipping
I want to know is of I load SQL 2005 on a Clustered Compute setup will it handle the SQL jobs, database requests with out the scheduler.
The question might be a bit tricky but any help is appricated
Thanks

SQL Server 2012 Data Tools was working fine for me but something must've changed, now every time I try to create a new SSIS project I get:
The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)).
When I try to open an existing project I get:
exception has been thrown by the target of an invocation
external component has thrown an exception (SSISUpgrade)
The issue seems to only arise with SSIS projects.I have already uninstalled SQL Server 2012 and reinstalled it and that didn't work.I tried to install Visual Studio 2012 Data Tools with BI and that also crashes when I try to create an SSIS project.Output of SQL Server SELECT @@VERSION is:

I am looking for some recommendations for memory sizing and options for a SQL 2000 Cluster. This is a two node cluster built on Windows 2003 ENT SP1 (x86). Both the nodes have the following hardware:
- 4 x Dual Core AMD Processors
- 16 GB Memory
- EMC Shared Disk
We are running six SQL 2000 instances and don't expect each of these instances to use more than 1.7 GB of memory. All these instances are going to support BizTalk 2004 Databases. I already have /PAE enabled on the nodes. I am looking for the following answers:
- Do I need to enable AWE on all the instances even if the instances ? Currently, we don't have that enabled and we have seen some issues regarding excessive paging even when there is physical memory available. The DBAs think that we don't need to enable AWE. I am bit confused on this one.
- We normally run 3 instances on each node and would like size the cluster in such a way that it can take six instances in case of a node failure
Any input will be highly appreciated.
I have a Windows 2003 Enterprise x64 edition cluster setup and functioning normally. Now, I am trying to get SQL Server 2000 installed as a failover cluster but am having some difficulty. When installing, I get the message '[sqsrvres] ODBC sqldriverconnect failed' in the event log. The message happens when the installer is trying to bring the SQL Server Service resource online.
I am able to ping the name of the instance successfully. I am able to manually start the 'MSSQL$InstanceName' service. I have turned off the firewall on both machines, but this did not help. I have the DTC Service setup as a resource in the same cluster group.
I also read http://support.microsoft.com/default.aspx?scid=kb;en-us;815431 which seemed promising, but did not reolve the problem.
Any help would be much appreciated.

I have a Windows 2008 R2 Always on Cluster with 3 nodes (two in the primary site and one in the DR site).
Primary Site:
-Primary Site Server1
-Primary Site Server2
DR Site 1 (to be decommed):
-DR Site Server1
Our company is planning on decommissioning the DR site. But before we do this, we want to add a 4th site to the cluster. Migrate the data...and then decommission the original DR Site.
Is it possible to have this configuration:
Primary Site:
-Primary Site Server1
-Primary Site Server2
DR Site 1 (to be decommed):
-DR Site Server1
DR Site 2 (NEW DR Site):
-DR Site Server1
IF this is possible, do I simply add the new DR site to the existing cluster (same steps as adding the first DR node to the cluster when the cluster was originally configured? or are there special steps?
We are trying to setup a system to system failover cluster using twonodes (x346) which each have a single hba running to seperatecontrollers on the DS400.For full redundnancy, IBM recommends dual path from each node but wedont need that. The current setup has two completly seperate paths. hbaon node 1 to controller A on DS400 and hba on node 2 to controller B.If i take a controller offline, failover works fine to jumo to othercontroller and throw all resources to it's node but if i shutdown anode- the cluster loses all attached storage and DS400 is unaware toswitch ownership to other controller.Is there a way to us mscs without dual path from each node?anotherwords... if either node or controller fails on a single path, wewant the other path to become active.our main goal is to use sql server 2005 clustering on the cluster.everything checks out perfect if i only use one controller on the DS400for both nodes but this brings us back to another single point offailure.I saw that Qlogic has MPIO drivers on thir website for the DS400 but itseems as though they are for 32bit systems and the install errors outwith:C:Driversmpio1.0.8.4 (w32)>install.exe -iPre-Installing the Multi-Path Adapter Filter...SuccessInstalling the Multi-Path Bus Driver...Failure.

This is a fresh install of SQL Server 2005 (64bit) on a Windows 2003 R2 SP2 64bit OS. The Cluster has been built and SQL 2005 has been installed (Database Engine(clustered), Analysis Server(clustered), Notification Server, Integration Server, Reporting Services). SQL 2005 SP2 has been installed.
Now, I want to install Notification Server, Integration Server and Reporting Services on the second node for high availability.
When I select 'Install New Components' from Add/Remove Programs, the System Configuation Checker tells me theres a version difference and to:
To change an existing instance of Microsoft SQL Server 2005 to a different edition of SQL Server 2005, you must run SQL Server 2005 Setup from the command prompt and include the SKUUPGRADE=1 parameter.
I'm using the same binaries as the original install. Could this be a result of installing SQL 2005 SP2?
Can someone help me out with this. I'd prefer using the setup interface instead of a command line script.
Hello
I've installed Windows 2003 SP2 in a stand-alone cluster (will be adding a second node later). I'm now installing SQL Server 2005 Developer Edition 64-bit extended and would like to have the "Create a SQL Server Failover Cluster" box to not be grayed out. Even when I check the "SQL Server Database Services" box, it still has the cluster box grayed out.
Any idea's?
TIA!
I am setting up my first sql node on a 2 node cluster and runing into this

Since as soon as you extend your mdx datasets manually you can no longer switch back into design mode without losing your changes, right?
If that's the case, is there some way to disable design mode completely? i'm finding that the GUI has the tendency to SILENTLY revert the dataset editor back to design mode while I'm busy editing a layout, thereby losing my carefully crafted MDX.
I have virtualbox installed on my notebook. For testing purpose, is it possible to setup SQL Server Fail-Over cluster using virtual box? I don't have a shared storage. How can I simulate that?

Other than impacts to users from install reboots, is that a hard requirement?
