SQL Server Failover Clustering Licensing
Mar 14, 2008
I have 2 Windows 2003 r2 servers with a SQL failover cluster installed across the 2 node. Generally I have been running off node1 with node2 as the failover partner. I have purchased the correct licensing for noe1 and from the following I do not need to purchase a license for node2:
Failover clustering is a process where the operating system and SQL Server 2005 work together to provide availability in the event of an application failure, hardware failure, or operating-system error. Failover clustering provides hardware redundancy through a configuration in which critical resources are transferred automatically from a failing machine to an equally configured server to help ensure continuity of service.
When doing failover support, a server is designated as the passive server. The purpose of the passive server is to absorb the data and information held in another server that fails. A passive server does not need a license if the number of processors in the passive server is equal to or less than the number of processors in the active server. The passive server can take the duties of the active server for 30 days. Afterwards, it must be licensed accordingly
http://www.microsoft.com/sql/howtobuy/activepassive.mspx
My questions are:
1) If I switch my cluster instace to point to node2 for testing node2 in case of a failover, would I need to purchase another licence ? This means I am not doing the repointing because of an 'event of an application failure, hardware failure, or operating-system error' ? Can you please provide information from MS ?
2) How are SQL Licences bound to the windows install in a SQL Server failover cluster configuration ? For instance if node1 legitimately fails due to an 'event of an application failure, hardware failure, or operating-system error' and you failover to node2. Then you think, stuff (forget about) node1 as I have 1 set of licences for SQL Enterprise already and therefore can run with a legitimate licence on node2. Can you please clarify ?
3) I have heard that only one server needs a license in a failover cluster. Then how does this fit in with any of the questions from above:
'The passive server can take the duties of the active server for 30 days. Afterwards, it must be licensed accordingly' ?
In the event of a legitimate failure, node2 would be running off the license purchased. So why are MS restricting the use of it for 30 days ?

Hi all,
We are the studying the possibilty of implementing SQL - Clustering for
Failover server.
Are there any third party tools readily available.
Any suggestion or checklist ??
Any suggestions or comments will be appreciated.
Thanks and have a great day.

Hi All,
We're planning to install a Server 2005 Failover Cluster and I'd like to find more information about licensing, etc.
Basic questions:
- What is the best O.S. to run? Win 2003 or the new 2008? And what version (datacenter, enterprise)?
- Since I'm going to use 2 machines, will I have to pay for 2 licenses (sql and windows - two lic. each)? Or just 1 license, since just 1 machine will be the active server?
This is for some web applications, so, web environment.
Any help?
Thank you!

We want to use sql 2005 failover clustering feature, so that upgrade sql 2000 is necessary. But some of the stored procedures built in 2000 are not working directly in 2005, set the compatibility level to 80 could make them work. In this case, can somebody here tell me if down grade the database level will affect failover clustering running properly? e.g. will data still be synchronized properly? Thanks in advance.

Hi all,
Please correct me , If I am wrong:
1) In SQL Server 2005 Clustering ( Active-Passive), only the Active instance need the license, as long as the Passive instance have same number of processors (or) less than active.
2) If we install , additional instance of SQL Server Enterprise edtion in Clustering, then we don€™t need to have any addional licence for the named instances.
3) Data files on SAN Ã RAID 10
4) Log files on SAN Ã RAID 1 (or) RAID 10.
Thanks.

I have a 2 node Microsoft 2000 cluster with a shared storage device. Iwant to create automatic failover for MS SQL 2000 server. I can dothat wit the following options:1. Active/Pasive (one instance installed)2. Active/Active (More then one instance/virtual sql serversinstalled)I have a question about option 2.Is it possible to have more then one instance/virtual SQL server,service only one database for example loadbalancing. ?, or when youcreate multiple instances/virtual SQL servers, does that mean you havemultiple databases ? If not why does a Virtual SQL server has to betaken over by a cluster node that didnt fail. Then you can actuallyuse option 1. Please advise!The documentation is not very clear on this issues.Regards,Nico de Groot

I have two SQL 7.0 SP1 (WinNT 4.0 SP 6.2) Servers using Clustering.
Problem: When SQLBox1 goes down, the Failover sends it to SQLBox2. When
SQLBox1 comes back up, the node stays on SQLBox2, instead of going back to
SQLBox1. This happens over 50% of the time, but not every time. Sometimes
it works fine.
I have done 3 hours of research, and can not find anything on this problem,
can any one a tleast point me in the right direction. I can hardly find any
troubleshooting on this issue. I do have January 2000 of the MSDN Library
installed on my machine if that helps, but there was not much on it in there
either (at least not that I found).

:confused:
In evaluating/comparing MS Clustering vs Hardware Failover Blades, has anyone come across any disadvantages/concerns for a Hardware Failover Blades.
Why would you install MS SQL 2000 Clustering when you can use a Hardware Failover Blade and use a SQL 2000 standard edition. e.g In an event a hardware failure occurs the admin manager brings over a standby hardware blade and reassigns it to the SAN (on which OS and SQL 2000) is installed and you are up and running.
Would appreciate any comments and suggestions to compare these solutions.
Thanks

I tested the failover clustering for SQL 2008R2.When I stop the SQL server services manully, the failover did not fail to another resource. At the Faiolover cluster manager, SQl server(MSSQLSERVER)  only show the status for offline. I think it should be move to another owner intead of just show as offline.

I am looking in to using Microsoft Clustering supported in NT Server Enterprise to provide failover support for 2 database servers running SQL Server 7. I was wondering if anyone had any experience with it--good or bad. I read the white paper and it sounds good, but I'd like to get some real
world application experience.
Thanks for any info.

Hello.
I am confuse and cant decide on how to setup high availability on our SQL 2005. Here's what on my mind and on resources list:
I plan to have mirroring on my SQL1 to SQL2 with the help of SQL3 as witness. So this would be automatic failover. My idea on mirroring is when SQL1 goes down, SQL3 would tell SQL2 to run and be the primary. It will automatically failover to SQL2. Right? My questions are:
1) How can I revert back to SQL1 once it is ready?
2) I read in one of the post that it is impossible to write in a mirrored DB, is this true? I mean, what's the use of failing over to the next node when it's not possible to write and update data/records?
3) If number 2 is false (i hope so), how would the data be synchronize from SQL2 back to SQL1. Those transaction that were made while SQL1 is down.
4) How about the connection string from the web applications? Would it be automatically point to SQL2? We have load balancing setup in place, would this help web application connection to automatically point to SQL2?
Another setup:
We have SAN in place (not yet used, but is planning to use for this SQL thing), EMC to be specific. My question would be:
1) For SAN setup, the data storage would be centralize. So would that mean that SQL1 and SQL2 services will use the same data and log file from the SAN storage?
2) How would you call this setup then? Can this be clustering type of high availability? Will clustering work under load balancing setup? I believe mirroring is not possible here? Right?
3) How can I setup my 3 SQL servers with the same theory in mind: when SQL1 goes down, SQL2 will take over. Data will be synchronize when SQL1 is up and running again. With automatic failover and reverting back to primary.
I read so much topics about this, but the more I research, the more I get confuse.
Any suggestions, comments, advice is 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.

We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?
Are we missing a service pack on the client?
Thanks,
Kimball

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.?

If SQL Server 2000 is loaded onto a 8 processor machine, can I legitimately
load Standard Edition, which will only use 4 of the 8 processors, or as
some interpretations of the license suggest, must I purchase Enterprise
Edition (i.e. you are not permitted to load SQL Server on a machine which
has more processors than the Product is capable of using) ?.
I know the "reasonable" answer, but what is the legal position ?

Hi,
My company is embarking on a data warehousing project. We are going to purchase a Windows 2003 server. It would be a dual processor. The specs are not certain yet so cannot give more details on that.
1. The data in the warehouse would be close to 150 GB.
2. There will be maximum of 10 users needs a SQL Server license.
3. Do not need analysis services.
What edition do I go with -Enterprise OR Standara? I want the least priced edition. I looked up the various links on Books Online but I am still not able to decide.
Say I need only 2 GB of RAM. Then here are my questions.
1. Since we are going with a dual-processor, do I need to purchase processor license for each of the two? Why can't I have one license on one processor only? What are the implications of this?
2. The 10 users that I am talking about will be remotely connecting to this Windows 2003 server and accessing the databae.
3. What exactly is Failover clustering? Do I really need it for my warehousing project?
4. Please help me pick the correct license. Here is the link -

I have a Windows 2000 Operating System with 4 processor, out of which I'm planning to use only one Processor for the SQL Server and leave the rest of the three processor for the OS.
My question is that do I need to buy the license for all the 4 processors or I can do with the only 1 that will be used for running the SQL?

Hello all,
I have a question concerning the ridiculous quagmire of SQL Server licensing…
How is SQL Server licensed when used to store session state information? Is MS claiming that this is an end user use of SQL Server functionality? Or, can we be realistic and say that I need a server license plus a device license for each web server?
Personally, I like everything about SQL Server except the licensing. Management at my company has already said that we’ll most likely be moving to either Firebird or Postgres after they found out how much it would cost to move from SQL 2k to SQL 2005. If MS wants us to buy processor licenses for SQL state servers, I guarantee we’ll be doing something else there as well. I wonder if Microsoft has any clue how much business they’re losing. Not just in SQL Server, but in their OS business as well.

Hello,
I am very confused about the licensing of SQL Server 2000 and 2005 (various editions), and any light you can shed will be greatly appreciated. I am learning VS2005, and need to build a website.
1. I know what a Client Access License (CAL) is.
2. I know what a processor license is.
My ASP.NET website might have 10 users, 100, or maybe 1,000 (I don't know at this point).They will have anonymous access to a main page from which they will have to log in, and from that point on be using SSL for anything they do.
I am getting conflicting information regarding licensing.
Questions:
1. Can SQL Server 2005 Express support what I need to do? (possibly many users)
2. Other than some of the fancy replication, analysis, etc that Express does not have, is there a good reason not to use Express Edtion?
3. Regarding SQL Server 2000 or 2005 (NOT Express): Does a single web application act as a single user thus the web application requires only one CAL. In other words: I am the only person who has direct access to the database. The ASP.NET web application will also have access to parts of the database. Will this scenario count as 2 "CALs"?
