They're Invading My Node!
Jul 23, 2005
We have a cluster set up at my office ( Active/Active ) that has been
pitched as some prime real-estate, apparently, as the best place in the
office for a database. Now it looks like one of my nodes is overrun with
databases! I'd like to set up some traces in profiler or performance
monitor to gather some stats in case we start to experience some degredation
in performance. I want to be able to point to some numbers to explain to my
boss why we shouldn't put so many databases on one node. Any suggestions
on what are some good counters to turn on? I'm thinking I should monitor
I/O wait and paging at the very least. I've also heard someone mention to
monitor page life expectancy, but I don't know much about this one.

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 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

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.

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.

Hello,
I cannot install SP2 on a new node that was added after SP2 applied to the primary.
We had the following scenarios. Node A SP2, node B RTM.
Scenario 1) Resources moved to node A (also MSDTC and Cluster group). Setup running on node A.
Setup warns (even in log) "The product instance XXX been patched with more recent updates."
Since it sees that local instance is patched, setup don't go on. I cannot select any clusterized instance.
Scenario 2) Resources moved to node B (also MSDTC and Cluster group). Setup running on node B.
Setup logs:
12/18/2007 13:13:55.175 Exit code for passive node: XXXXA = 11203
12/18/2007 13:13:56.972 The following exception occurred: No passive nodes were successfully patched Date: 12/18/2007 13:13:56.972 File: depotsqlvaultstablesetupmainl1setupsqlsesqlsedllinstance.cpp Line: 3422

12/18/2007 13:13:57.440 Watson: Param10 = 3042
I undertstand, he cannot patch an already patched node (A). Setup stops ignoring local node. So... how can I just patch a single node (B)?
I read uninstalling Setup Support Files and reinstalling them will help faking an RTM node to the setup, but during uninstall I got the following warning "Warning 26002: The following product(s) is dependent on Microsoft SQL Server Setup Support Files (English), the key will be broken€¦" and it lists one of our instances (just one). We will test it virtually, we cannot afford loosing that instance.
Thank you!

How I I only return values and not empty cells? SELECT xmldata.query('declare namespace ACM="www.mydomain.com"; (

Hi all,
I have a question about re-creating the sql portion on either node a or b in a clustered situation. Is it possible to do this without affecting the working node and database ? or is the best solution to make a ghosted image of the node after install is complete and if the node fails just get to a point on the affected node where you can copy the image back?
Thanks for any feedback.

<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"

its possible to check what the first node is before loading an XML file. The file name is just a combination of random numbers e.g. TMP_18028423.XML there's no way of knowing what it contains I need to check before loading into a table. Then I'll process the data from the temp table. i need to check if the first node is <Departments> then load the file that contains departments.
Here's the script I'm using to load the File:
CREATE PROCEDURE JobDepartmentXMLImport
@FileName varchar(256)

--Create temp table
CREATE TABLE #TempDepartment(

Need some advice .
Our management want to have two instances of SQL Server 2005 in Clustered environment.
First instance will serve existing application and Second instance will serve their new application.
As Microsoft suggests that, its not a good practice to have multiple instance on the same node, until you have any compelling reason to have such setup. The compelling reason what the mangement have is , some time ago they used same instance for both the application. What happened was, the secondary application took all the resources from primary(main) application, and server went down( this was past.).
So, now in clustering they want to have their first instance (which will serve our existing application) with enough CPU cores & memory so that it can run smoothly and then have second instance with the remaining CPU power & memory. So ,in case if second instance tries to eats up all the resources, it can eat what it have , it cannot take resources from primary instance.
But, what my idea here is:
Initially, dont install second instance for new application( in clustering environment). Instead ,use existing servers for the upcoming new appication where production & DR is there right now ( Standalone servers).
What i mean here is: After making sure that the existing (Primary) application is comfortable in clustering environment (in PRODUCTION) , until then, run the second application on the old PROD box & old DR will serve as its DR. So ,by going in this way , we are not installing initally two instances on the same node. When the life is good for the first instance, then based on those results, we can think for the second instance.
Ii wanted to know from you guys, what you think about this. Is this idea look feasible. Please let me know.
Thanks for reading all this

We have been working on a project to upgrade the servers in our 2-node SQL Server environment. I evicted a node after removing it from the instance. We added the new node under a new server name. I then start the Add remove programs, choose to change the SQL 2005 environment, type the virtual server name. Choose to maintain virtual server, pick to add new node. All seems well, I enter all prompted questions, and when the install begins I get the error below.
Product: Microsoft SQL Server 2005 -- Error 1706. An installation package for the product Microsoft SQL Server 2005 cannot be found. Try the installation again using a valid copy of the installation package 'SqlRun_SQL.msi'.
So I copied the SS2K5 Enteerprise Edition software to the local C: drive, point it too the 'SqlRun_SQL.msi' in the setup folder and still get the error.
Any one experience this or have any suggestions?

We have:
A Microsoft cluster, (SQL Failover cluster) with one node as the domain controller. The cluster was built off site and the domain name used is the same as our existing domain where we eventually need to install this cluster.
We need: (At least I think we need:)
To remove node 2 from the "cluster domain", DCPROMO node 1 and eliminate the "cluster domain". We then need to join the cluster (nodes) to the existing domain. We also need to recreate the accounts and groups used during installation.
Questions:
1) What will happen to the "domain accounts" used when installing SQL2005? (Other than they will go away. I mean what adverse impact will that have on the installation?)
2) Will I have to re-install SQL 2005?
3) Is my paranoia real or imagined? (Will Elvis live?)
Any prior experience with this would be greatly appreciated. In fact, a WAG is appreciated too.
Regards,
Mike

I currently have a single node cluster of SQL2K5 installed on Windows 2003 Server. A second node has been purchased and ready to install but I need to know what needs to be done to configure it to be the failover for SQL.
Is it just a basic install that needs to be done on the second node or do I need to re-install the SQL Services on the first node to have it properly recognize the second node?
Thank you,
Ryan

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"?

Cluster services gives the high availability needed - that is great.But I have never seen any discussion about what happens when a nodefails - what do you do to get everything back to the active-passivetandem.I imagine there is not much difference in terms of recovery procedurefor either active or passive node. So I'm just going to make up ascenario that we have encountered. The system hard drive (not theshared disk) on primary node fails. Cluster fails over to the passivenode. Following are the problems I have at hand:-After installing windows, I need to install driver and configure thepermission to access the SAN. There is no way I could do it since thesecondary node has exclusive access to the disks.-Imagine I got that working, is there anyway to install SQL so SQLwould know this server used to be the primary node and attach the DBand translog automatically-Finally, there is no proper way to apply SQL 2000 service pack 3a.Originally when the cluster was fully functional, the service pack wasapplied to active node and that automatically upgrades passive node.Now we have a machine without 3a and a machine with 3a alreadyinstalled. See any problem?Consider all of the above as this one big question: What is a properprocedure to restore a cluster when one of the node goes down? Whetherit's the active or passive node.

We had an existing 2 node active / active cluster, 1 running a default instance of Sql Server 2005 Enterprise Edition 9.0.3152 (SP2 + Hotfixes) and the other running a named instance of the same version.
We recently added 2 new nodes to the cluster, they were successfully added and we tested the cluster group failover successfuly to the new nodes.
Last night we tried to install Sql Server 2005 Enterprise edition on the new nodes.
I followed to proper proceudure of modifying the installation for both instances and selecting the 2 new nodes to apply them to. This went 100%. Sql Server 2005 successfully installed for both instances on the 2 new nodes, all log files were successful.
We then tried to apply SP2, we tried the following:
1. We ran SP2 from the active node, but when we go to the screen to select what you want to apply SP2 too we could not select anything, if you clicked on database engine the message said that these instances were already at a later version and we could not proceed. This is how i successfully applied SP2 to the original 2 node cluster but it does not work for additional nodes to an exisitng cluster.
This is also what all the documentation we could find said, refer to SP2 release notes under the topic "Failover Cluster Installation", it is also the method we found when googling.
2. We then tried what is described under SP2 release notes "Rebuild a SQL Server 2005 SP2 Failover Cluster Node".
We ran SP2 from the new nodes while they were passive, but when we got the screen where you select what to apply the SP2 too we could not select database engine the message at the bottom said that SP2 must be run from the active node and that we were attempting it from the passive node, this is what we tried in step 1 described above.
3. This was a last resort. We were advised to try failing over the instance to the new node and then running SP2. Personally i thought this was a bad idea, one should never fail over a instance of sql server to a node with incompatible binary versions and secondly when we installed sql server on the new nodes a warnng popped up before hand stating that the instances were at a later version and that the new nodes must be at this version before attempting fail over. I thought that sql would not even start, to my surprie we successfully failed over the sql group to the new node, when we ran SP2 it looked good we could select the database engine on the new node to apply SP2 too, BUT after clicking next after a few seconds the SP2 installation just closed, NO INFORMAITONAL MESSAGES NO ERRORS NO WARNINGS it just closed an never came back.
I had never seen this happen on a cluster before, needless to say this made me very nervous so we failed the sql group back to the original nodes and gave up.
PLEASE can some tell me how to apply SP2 to 2 new nodes in a 4 node cluster all methods descibed in SP2 release notes and other documentation as descibed above in step 1 and 2 do not work !
Thank You
