MS SQL Clustering And Failover
Jul 20, 2005I 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

Failover Clustering Without SAN && SCSI ?

I dont haveany shared disks and SCSI drives. Can I still configure the Failoverclustering?I would like to know more about the need for the shared disks in theFailover clustering.Please shed some light.RegardsKumar

Feb 20, 2000I 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).
MS Clustering Vs Hardware Failover Blades
Sep 29, 2004: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

View 3 Replies View RelatedSQL 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 ?
Using Microsoft Clustering For Database Failover Support
Jun 9, 1999I 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

Server Failover Clustering - Costs And More Details
Mar 24, 2008Hi 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!
SQL Failover - Mirroring, Log Shipping, Clustering, Load Balancing
Jun 14, 2007
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!
Will SQL Server 2005 Failover Clustering Still Work When The Database Level Is Set To 80?
Nov 2, 2006We 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.

No Failover And Client Crashes ODBC DSN Setting For Failover In Connection String
Mar 3, 2007We 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

Transfer A Database From Non-clustering To Clustering Env.
Nov 13, 2007We 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.?

I recently added a column to an existing table with a getdate default. When doing a query from that server everything works fine. When a query is ran from a remote server I get an SQLOLEDB error message saying 'inconsistant metadata'.

Is there a way to find out which user defined procs/child packages etc are been called in SSIS packages using some metadata. The idea is to have a document which lists the number of packages called, whats sprocs and child packages are executed by those pkgs..
I have checked the SSIS metadata whitepaper but that is too generic.

Metadata Refresh
Feb 26, 2007-We are using SSIS packages for various kind of data load from excel source.
-If there are any change in the data type or format of excel, the package cries for the Metadata mismatch.
-During design time if you accept the metadata changes, all things work fine.
But in our case we have deployed the packages on Production Server, now the excel file format/data has changed. The packages are expecting a different metadata so they are not working at all.
Do you have any suggestions for the above problem?
Thanks, Vijay.
Metadata Question
Apr 4, 2008i am using icolumnsrowset interface to get some metadata about the columns in a rowset, but i never got unique and primary key columns in the columnsrowset, they always return null, when using sqlcedataadapter i simply add addwithkey option to the adapter to determine it, but i dont know how to do it by using ole db interfaces, i have tried to set DBCOLUMN_KEYCOLUMN flag to true on ccommand<cynamicaccessor, crowset> but it seems it rejects it, generating an unknown error, error object says almost nothing except that 'errors occured[,,,,,]' text
can someone tell me, how can i retrieve columnsrowset with that unique and primary key sections filled?

METADATA DEPENDENCY
Nov 9, 2007Hello everybody,
It's now quite some time that one particular behaviour of SSIS is really frustrating me and I would like to know if I'm the only one experiencing this problem or if other people have the same problem.
The issue I'm talking about is SSIS 'dependency on what is written in the XML files describing the flows.
Particularly with the Data Types of columns.
I'm explaining myself: Imagine your are developping a flow containing several numeric(18,0) columns...
During the flow you have to perform a lookup on an Integer Field.... Of course this operation is not allowed as a numeric is not mappable with an Integer... (This is, in my opinion, a nonsense as an implicit conversion has to be possible).
as a result of this behaviour, I decide to change the datatype (numeric) from my source query to an integer and use it in the Lookup which of course succeeds but now I have a second problem: each lookup in my flow has an error handling branch which I'm joining back using a Union transform. and there we have the second irritation: the Union transform doesn't replicate the Data Type changes that occured upwards in the flow... worse: it even has no interface to let you modify the data types like the advanced editor of some transforms or data sources. (I've just lost a complete dataflow while trying to modify it manually in the xml file directly :-( for those who are considering modifying directly the XML, don't!! You are asking for trouble and a lot of frustration when you'll switch back to the designer to see the effects )
My question is now: Am I misusing SSIS?? Is there somewhere an option to activate in order to get this behaviour fixed??
Has anyone else experienced this problem?? How are you solving this??
Are there any plans in the future to loose this dependency on the datatypes or at least add some implicit conversions??
Thanks in advance for your replies, suggestions,questions and other thaughts about this subject :-)

MetaData Backup
Feb 12, 2008
Hello-
I have a question regarding my metadata information. I finally setup my fixed width file which took some time. Is there a way that I can backup my metadata so I wont have to recreate these setting again. I'm thinking the format of the file is stored in the metadata so if I have a user running the SSIS package from the Business Intell Studio they wont reset all of my columns. Is there a file I can restore or backup if this should happen

Metadata Visibility
Feb 25, 2008Hi,
I'm running the following query in SQL Server 2005:
select name from master..syslogins;
It is being executed from within a stored procedure.
For user 'sa' - I get the complete list of users.
For a user (say 'user1') with NO sysadmin privilege - I get only two names: 'sa' and 'user1'
Is there a way for me to retrieve the complete list of users even for 'user1' without making any changes to his profile (or making very MINIMAL changes to profile)?
I don't want to give sysadmin profile to this user.
I know 'GRANT VIEW ANY DEFINITION TO public' works, but don't want to do that either.
