We are running on SQL 2000 on Windows 2003. We have active-passive
clustering set up. We have 16 GB of RAM on each box. This past
weekend, we failed over. I noticed that the Total Server Memory went
from about 15.5 GB to 8 GB. I have been trying to figure out why this
has occurred. Any help would be greatly appreciated.
1. Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk.
2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode.
3. after fail over done to 2nd secondary node what mode in production(readonly or read write).
4. how to rollback to production primary ,will change data in secondary will get updated in primary.

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 RelatedHi I just set up a new cluster and everything was working. Now when I try to test failovers like unplug the public network card etc...
The cluster group fails over correctly but my data and log array's dont failover.
So I unplug the network cable from node 1 (active) the cluster group with the IP, name, and Quorum disk fails over to node 2 but the other groups sql data and sql log stay on node1 and dont failover.
Any ideas?
TIA
Hi all:
I was wondering what will happend to the transaction when the cluster failover from one node to another?
In my case the database is in node-001 and I need to restart the server on node-001. So I need to have the database failover to node-002, so I can work on node-001. During this process, will it effect to end-user?
Thanks

We need to start testing our Microsoft cluster servers.
Has anyone heard of any plan or products one can use to test
the failovers?
Please advise

We need to install the webservice and the database on a failover cluster. Our plan was to install the web service on node 1 and the database would naturally be on the cluster aware sql service. We know the RS will not be cluster aware and if node1 bites the dust, reports will be out of business.
We were planning to do this tommorow on development, but then found this little tidbit - read the very last paragraph
http://www.microsoft.com/dynamics/crm/using/deploy/clusteringssrs.mspx
SQL Server Reporting Services failover cluster configurations that are not supported
Do not deploy both SQL Server Report Services and the reporting services databases on each node of a multi-node cluster. Moreover, do not deploy SQL Server Reporting Services in a two-node cluster environment that consists of an active node and a passive node where the passive node becomes active during a failover.
They don't explain why not to do it - as if it will destroy your machine! This is our main dev cluster and we don't need it to go down.
We will not be installing the RS on each node, just one. But I was thinking that if the dns entry for the service points to N1, it will continue to function and make successfull DB calls to the sql server cluster name.
Could this work? I've found posts of people installing RS on both nodes and having success - but this would probably require another license...which we don't have.
Thanks so much for your help - it is greatly appreciated.

Hi. Was hoping to get some advice on applying a hotfix to a SQL Server 2005 failover Cluster.
The hotfix I am applying (KB933508) relates to a Maintenance Plans issue with Server 2005 Service Pack 2. During installation I'm advised that unless the SQL Server and other services are stopped a reboot will be required, although I can still install the hotfix. However the installation is failing. There are error details in the relevant logs created in C:Program FilesMicrosoft SQL Server90Setup BootstrapLOGHotfix to the effect that the 'Debug' value in registry key 'SoftwarePoliciesMicrosoftWindowsInstaller' can't be read and that SQL Server was unable to add a user (the account under which SQL Server Agent and Analysis Services run) to a local group (the domain group in which SQL Server logins are contained).
Is this something simple like explicitly shutting down the services first before applying the hotfix or is there something else going on?

Hello,
Does any one know, any software out there that can provide a solid failover / cluster / high availability solution for SQL Server 2000 Databases.
I have tried Incepto but it requires an extra column in every single table that involves in Replication and its not gonna work
So Please advise.

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?
View 1 Replies View RelatedHow to create a SQL 2012 Failover cluster using VMs?
View 9 Replies View RelatedI have a 2-node Windows Cluster and File Share Witness with an availability group. The cluster is set to sync and auto failover. I'm using SQL 2014 and Windows 2012R2. I'm trying to understand the steps to apply Windows Updates that require a restart. Are the steps something like this where ServerA is the primary replica and ServerB is the secondary replica.
Apply updates to ServerB.
Restart ServerB.
Fail ServerA availability group to ServerB using ALTER AVAILABILITY GROUP MyAvailGroup FAILOVER;. Server B is now the primary.
Apply updates to ServerA.
Restart ServerA.
Fail ServerB availability group to ServerA using ALTER AVAILABILITY GROUP MyAvailGroup FAILOVER;. Server A is now the primary.
What I don't understand is where Drain Roles on the Failover Cluster Manager fits in?
We have 2 nodes window Server 2012 R2 and SQL Server 2012 Enterprise Version cluster setup. We can switch roles and Node to one node to another and revert back to previous node with out any issues. But we are facing when one Node is restarted. We could not restart that Node in cluster Service start in Failover cluster Manager. Error Details is displayed as below inside double code."Cluster node NODE1 could not to join the cluster because it failed to communicate over the network with any other node in the cluster. Verify the network connectivity and configuration of any network firewalls."
I checked windows firewall. windows firewall is all of in Node1, Node2, SAN and DC.I have disabled and enabled the Internal and private network of Node 1. I have validated the cluster. it is showing no error though.
Node1:

[code]....
Private Network: Not configured.pinging to each other ip is successful from one node to another.
I noticed in installing a SQL2005 failover cluster instance,that it is not necessary to install on both servers. Installing on the primary node automagically installs to the secondary node. Does this constitute a COMPLETE install? It all seems to work. BUT this process does not intall client pieces (SSMS, for instance) on the secondary node. If you want that stuff there, do you then go to that box and just do a client install?

We have sql server 2005 installed locally on 2 servers and want to set up failover clustering. Do we need to uninstall what we have then install as failover cluster? Thanks.
When trying to install SQL 2005 as a failover cluster in a Windows 2003 64 bit SP 2 cluster, I receive the following error when trying to select the installation path after choosing to install as a failover cluster.
_________________________
TITLE: Microsoft SQL Server Setup
------------------------------
The drive specified cannot be used for program location. Program files must be installed on a valid local disk available on all cluster nodes. The valid values are
__________________________
There is a knowledge base artical that says this can be from not installing the software with an account with admin permissions on all the servers in the cluster with the 64 bit install, but the account I used is an admin on both servers.
The only thing that I can think is causing the problem is that it is setup to boot from our SAN and it is using one fabric. By default Microsoft Clustering doesnt like this, but we use the newest storeport driver and applied the registry key supplied in KB article 886569 to resolve this. I could not find any documentation showing that this would limit a SQL 2005 Failover Cluster from seeing the shared storage.
Any help would be greatly appreciated.
I am using SQL 2012 SE with clustering on Windows server 2008 R2. Now I want migrate it to windows server 2012 with minimal down time. So I want to evict the passive node and add a new node with windows server 2012 and install sql server 2012 SE on the new passive node and perform a failover(make the node with 2012 OS as active) and then evict the new passive node and add another node with windows 2012 and then do the same thing?

Hi,
I've a problem with my failover cluster. It's a two node cluster and if the active node fails, the second one overtake the database and everything is fine. But only the reporting service doesn't start on the second node. The service is off. All other ones are starting correctly. Is there to configure something special to the Reporting Services?

I have a production failover cluster running SQL Server 2000 at SP3that I want to upgrade to SP4. I do not have a test failover clusterto test with so I need the install on the primary server to work thefirst time. Per the information I have I just install the patch on theprimary server and it will install both on the primary and on thesecondary.However, I remember when I did the initial install and it failed. Thefirst problem traced to the fact that the install uses temporary filesunder the profile of the installing administrator and the id had neverlogged into the second server so the install failed on creating thetemporary file. The was a second problem that related to an OS featurethat had to be off for the install to work.If anyone out there has done this upgrade and remembers encountering aproblem and its fix/workaround I would appreciate a head up warning.Thank you-- Mark D Powell --
View 1 Replies View RelatedI'm getting the following error when I go to create a cluster in the Failover Cluster Manager in Windows Server 2008.
"The address 10.10.10.111 is not valid for its associated network"
I'm following the instruction in the book for the 70-462 exam. There was a step that had me create a DNS A record for the address sql-cluster.contoso.com. The IP address was mapped to 10.10.10.111. I'm not sure if this is the culprit but its the only time I used that IP address in the setup.
Below are 2 screenshots. The first screenshot is the error. The second screenshot is my DNS console.
I saw following point on Technet article about RBS.The local FILESTREAM provider is supported only when it is used on local hard disk drives or an attached Internet Small Computer System Interface (iSCSI) device. You cannot use the local RBS FILESTREAM provider on remote storage devices such as network attached storage (NAS).It looks like that we cannot use FILESTREAM on Failover Cluster because to setup Failover Cluster we need to have NAS. But then the NAS is made available locally for Failover Cluster so FILESTREAM should work right?Found another article which talks about setting up FILESTREAM on Failover Cluster. URL...

Hi we have a two node windows 2003 x64 cluster, each running a SQL 2005 instance. I've added a new node to the cluster and am now trying to set up a new instance of SQL 2005 on the new node (node c). During the install i am getting a failure just after the stage where you choose the features to install. I'm selecting SQL database engine with Failover Cluster. When i click next i get a message which states:
"The drive specified cannot be used for program location. Program Files must be installed on a valid local disk available on all cluster nodes. The valid values are"
I've read a number of articles about possible causes for this and i've checked all the suggested causes but none of these have made a difference. The cluster disk resource is healthy and can be failed between all nodes in the cluster. No errors are generated. I am using an account which has domain admin rights and I can access all admin shares on all nodes. Some of the articles i have referenced are here:

I've tried uninstalling all components etc but still i can't get it to work. The next step is rebuilding the server completely so does anyone have any suggestions?
Any suggestions would be greatly appreciated.

I'm trying to do a SQL 2008 cluster installation.I installed one node and now I'm trying to add a failover cluster node.in the "add Node Rules" I get following message:
Rule Check Result...Rule "SQL Server Database Services feature state" failed.The SQL Server Database Services feature failed when it was initially installed. The feature must be removed before the current scenario can proceed.
The main objective is to have a third party program operate on a failover cluster. The OS is Windows Server 2012 Datacenter loaded on 2 nodes. A virtual node exists along with supporting disks. This client software uses a SQL Server database. SQL Server 2012 Enterprise is installed and operating in a failover environment. However the client software is not failing over. If the connection to node A is lost, SQL Server fails over to node B. But the client application does not.
What needs to occur in order to associate the client software with the failover cluster? This software has 6 services total installed. Some are referred to as servers - looks like to communicate between remote client computers and the database. What is the process to associate the client software with the failover?
