Clustering

Feb 14, 2005

I have a question relating more to documentation and support. I'm trying to find documentation on clustering.

I remember quite some time ago I found a white paper that literally walked you through every step involved in setting up a SQL Server failover cluster. I had also found a white paper that walked you through setting up an Active/Active cluster.

I've been going through Microsoft's site, but all I've found are little bits and pieces.

If anyone can point me in the right direction, or even provide a link, etc. as to where to find some good solid documentation, that would be awesome.

Thanks!!

Transfer A Database From Non-clustering To Clustering Env.

Nov 13, 2007

We have 2 env. : Testing and Production, both are running Windows 2003 Enterprise Server with SQL Server 2005. The difference is Testing is NOT running Windows cluster but Production do so, what is the best way to transfer a database from testing to production?

We have another systems that both testing and production are running on NON-cluster and we use backup/restore to transfer the database, can it apply in this case.

And I found that there are a tools called DTC, which can transfer all DB objects from one DB to another, is it a best way to transfer between non-cluster and cluster env.?

SQL Clustering-NT Vs W2K?

Nov 20, 2001

We are in the process of consolidating all our SQL6.5 and SQL7 databases to a single SQL 7 server - once completed we want to setup a 2 node SQL7/2000 cluster on either NT4 Enterprise or W2k Advanced Server. I would therefore appreciate any advice in choosing between the two platforms based on cost, ease of setup & configuration and ongoing reliabilty & uptime etc - we currently have no NT4 Enterprise Servers so would have to purchase these licenses anyway. Correct me if I am wrong but I also understand that setting up a cluster on NT4 Enterprise is considerabely more complicated and time consuming than on W2K Advanced Server? Any advice would be greatly appreciated..

regards

SQL N + 1 Clustering

Mar 4, 2008

We currently have a cluster configuration that is running as failover with one shared SAN storage solution. Two servers running Windows Server 2003 Enterprise and SQL 2005 Enterprise. We have two nodes right now running in failover and we will be purchasing a third.

Everything is working now, but we would like to move to an N+1 configuration with two active nodes hosting a separate SQL instance each with one failover node. I've seen N+1 mentioned on about a dozen Microsoft websites, but I cant find any documentation on how to setup or configure this clustering method. Has anyone ever set up a configuration like this or seen any documentation on how to do it? Is it possible to run failover with three nodes, two of them being active?

Any insight would be greatly appreciated.

Clustering Questions

Jul 24, 2000

Does anyone know the answers to either of these, given that we are talking about an active/passive cluster using MSCS, and we use Groupwise for mail (don't ask!)?

1) How do I configure Agent Mail on the cluster under this setup?

2) How do I set up linked servers from this setup to other (non-clustered) SQL servers - I can set up the cluster virtual server as a linked server from the others OK, but the other way around doesn't work - perhaps not surprisingly, but is there a way around it?

Thanks

Martin

Clustering Sql7

Aug 11, 2000

I need some documentation on how to trouble shoot clustering SQL7EE. I have setup the cluster and looks like it is working but I missed somthing. When I test a failover by pulling the Network cable to the main network not the heartbeat network both boxes lock up. I can failover by powering down one box and using the MSCluster Admin. I am using NT40 6a on Dell PowerEdge 2400 and PowerValut 211s

Clustering With NT/SQL Server

May 1, 2000

Those of you who are using MS Clustering, what are some advantages vs. a third party product such as "Double-Take" ? If you have used "Doube-Take" I would be extremely interested in your thought of the product.

Is it relatively easy to setup and configure with and environment
that's using all the standard products of BACKOFFICE (SQL Server 7.0 Standard Edition, NT 4.0 Standard Edition etc...)

Any hints, tips, etc... would be also GREATLY appreciated.

Thanks in advance.

SQL Server Clustering

Jan 28, 2000

I have a question about database clustering. I am loking for the solution for the databse scalability, performance and zero downtime especially for MS SQL Server. As my understanding (correct if I am wrong), only Oracle provides 2 DB Servers (parallel server) or NT clustering for two sql servers. The drawback for these solution is only one server is working and another one is standing by. It is not efficent (which only 50%). Is any way that I could built the DB server farm which every DB server is working, if one failed, throw it away, rest of them still working; if I need more power, just add another db server box.How to solve the data sync problem ? Replication is not good for more than 4 or 5 db servers in the farm. Disk mirror is not good since if the server is down, there is no way to access the disks. DO you have any good idea ?

Clustering SQL Questions

Sep 7, 1999

2 Clustering Questions for you.

1. If I cluster 2 SQL servers in an active/active configuration and want to have a seperate disk array to house the data, do I need to have 2 disk arrays, one per server, or can I have one disk array?

2. When installing an application's database on the first(primary) sql server in an active/active configuration, do I need to install it on the second(secondary) server also? The second server will pick up the processes if the first fails.

Requirements For Clustering

Jun 17, 2005

For SQL 2000, what are the licensing requirements for a clustered environment? I thought you needed datacenter for the OS, is there a clustered version of sql server, or do you need 2 copies of enterprise edition. Also, if you cluster can you license sql cals for clients, or do you have to do by processor?

SQL 2000 Clustering

Mar 12, 2002

We are going to implement a SQL 2000 cluster in an active/passive setup. We are going to use multiple instances. What I am confused about is the naming of the virtual server and instances. In the microsoft documentation it states that all instance/virtual names must be unique across all nodes in the cluster. But the client always specifies the same virtual server name when connecting so how can the names be unique across all nodes??

I would have thought that if there was an instance created called inst1 on node A then during the installation that instance name would be replicated to the failover node B. When installing another instance on Node A do you have to specify a different virtual server and instance name on the failover node B??

Please help!!!!!!!

SQL 2000 Clustering

Jul 26, 2001

Should SQL Server 2000 (Enterprise edition) running on a Win2K Advanced Server (Active / Passive) cluster fail-over seamlessly?

We have been assured by our suppliers that current client connections (ODBC using TCP/IP) cannot be maintained during a fail-over. The result is that during a fail-over the client applications crash and users have to restart.

Do we have to modify the client application so that during a fail-over it will attempt to re-establish a connection?

Pointers to any resources for SQL 2000 clustering would be gratefully received (especially any which support the view that fail-over should be seamless).

Many Thanks

Mark

Is SQL 2000 Clustering Cr*p????

Jan 11, 2004

Howdy,

I have had questions from management about whether SQL 2000 clustering on windows 2000 is any good.

We are looking at spending *quite* a bit of money to implement it, but I want a "from the trenches" opinion of what its like , from the people that actually use it & look after it.

e.g.

DOES IT WORK LIKE IT SHOULD????????
Is it reliable?
Is it resource hungry?
Can I trust it to do what its supposed to do?

All repsonses very welcome. No response too small.

Thanks for your help.

Cheers,

SG.

Reads, Clustering, Etc

May 1, 2008

server: QAT on clustering server ----> 23 seconds
----------------------------------------------------
SS 2000 developer edition SP4
win NT 5.2 (3790) SP4
MeM 7935 MB
processors 4
root directory C:program files...
use a fixed memeroy size 640 MB

reserve physical memory for sql server
minimum query memory 1024 kb

use all available processors
minimum query plan threshold for considering 5

dynamically configure sql server memory

use all available processors
minimum query plan threshold for considering 5
PROFILER READS = 598

----------------------------------------------------
Making story short. I got an application that hits only 1 database called RECORDS. I'm getting different duration when running an application. 23 and 3 seconds.
Same database, same objects and same application.
SERVER QAT is our staging server, means lots of databases
SERVER MILLER is just a server i just assembled, means just one database (RECORDS).

Not sure if it's because it's a clustering server that is causing the issue nor the reads. If its the reads, what is causing it? Do you think is the how the memory is configured?. Will the experts pls stand up?

Hi all,

We have 2 database servers with same configuration.

One is Development server and the other is Production server. The Production database server is clustered.

We find the same queries taking more time in the Production server which is a clustered server.

Will the clustering affect the performance in any way.

Any help would be appreciated.

Thanks,

Whether To Do CLustering Or Mirroring

Clustering or Database Mirroring

I am totally confused . As i read from SQl-server- performance , Clustering doesn't protect data. It is server level.

Can any expert throw a light on me?
