Will A SQL Server Cluster Provide Me More Performance?
May 20, 2007
I have a database that stores the information of a third party system. The system where the database is running has reached its performance and hardware upgrade limits. I don€™t want to separate the database objects in two different database servers. How can I add a second server to increase performance? A cluster will help me in this case? Or there is any other way to group servers for performance?
This is the first time I am using SQL Server 7.0 on a bussiness machine, I need to apply password on the database, OS is windows XP professional, need u r help on this.
The overly complex MSDN library is proving virtually useless to me. To give you some background, I've programmed PHP / MYSQL websites, in-depth VBA programs for Excel and a bit of non-database work in various languages - I'm an amateur.
I've just bought a new PC (2g Ram, Core 2 Duo, Vista Home Basic) and would like to run Web Developer Exp, VB Exp and SQL Server 05 Exp.
Note. I have installed all three and run through Microsoft's video tutorial, until I hit a snag at the start of Tutorial 2. When try to create a new SQL Database in WebDev, an error saying either SQL Server is not installed or operating correctly (could Microsoft provide a more specific error or what????)
The questions Microsoft need to answer are:
1. What are the hardware requirements for SQL Server 05?
2. What are the operating system requirements for SQL Server 05?
3. What does IIS have to do with SQL Server 05?
4. How do you know if you meet the IIS requirements for running SQL Server 05?
5. Exactly what elements of SQL Server 05 are affected by different levels of IIS?
6. Can anti-virus or firewall software cause issues.
I have SQL 7 running on an Active/Passive Cluster configuration. My problem is that I can not see any SQL objects listed on perfmon. Can this be because of the Cluster configuration? I trying to run perfmon directly from the main system console.

Hi,I have SQL Server Express Edition. I tried working out some ASP.NET Labs in my local system. Here is the link of the Virtual Lab which I tried. http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032286906&EventCategory=3&culture=en-US&CountryCode=USI recieve this error in my local system. An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)I tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
Is it possible to create a cluster configuration, where 2 (or more) SQL Server instances running on different servers will simultaneously serve the same database attached to the same storage? Something like this:
Instance A Instance B Instance C (active) (active) (active) | / | / | / SAN for Database and Quorum
The point would be to improve reliability and performance at the same time. All nodes would share load. If a node fails, the other nodes still work and take over the load.
I know a failover cluster can be done, where 1 instance is active and others are passive (active/passive) which improves reliability, but in this configuration just 1 instance is serving at the same time.
(As far as I understand, the active/active configuration is meant to run different databases on 2 (or more) instances such that the databases on a failing node are taken over by any other instances in the cluster.)
Why don't you folks (SQL SERVER Management Studio Team or SQL SERVER Database Engine Team) provide an option by using which I would be in a position to know what all the other objects are depended on a selected object and vice versa. That means:
When I select a Table within the SQL SERVER Management Studio if there is an option for understanding "Which all the objects (tables or views) it is depended on (I mean Foreign key and etc... kind of relations) and also Which all the objects (Tables, Views, Stored Procedures and etc...) are using this table", It would be of great help for all developers.
We are planning to upgrade the SQL Server in our production environment from SQL Server 2000 to SQL Server 2005. This is a 4 Node cluster environment with 3 Databases on 3 Virtual instances. The main requirement is to achieve this with no/minimal downtime.
Could you please suggest or direct me to any documentation for the best practices used to upgrade such an environment?
We're upgrading a SQL Server 2000 cluster (Active/Passive) running on Windows 2000 Server to a SQL Server 2005 Cluster running on Windows Server 2003. We can't purchase new hardware and we have no spare hardware. We also need to move from Windows 2000 Server to Windows 2003 Server at the same time. We want to keep downtime to a bare minimum.
What we were thinking was the following steps... Anyone try this?
1. Break the link between the servers.
2. Install a fresh copy of windows 2003 server on one side along with SQL Server 2005. While this step is running, the active node would still be live on Windows 2000 Server and SQL Server 2000 serving our customers.
3. Restore a copy of a backup from the active production side to the node we're upgrading and at that point we would bring the active node down, switching the active node to be the newly upgraded server.
4. As a final step, the old active node would now have the link to it broken, we would install a fresh copy of windows 2003 server on it and sql server 2005. At this point we would bring it back into the cluster and the cluster would be complete again.
Need your help and guidence for doing upgrading SQL Server 2000 Cluster to SQL Server 2005 Cluster.
Let me explain my current environment.
1. Currently SQL Server 2000 Cluster environment is running on Windows 2000 Server we need to upgrade this to SQL Server 2005 on Windows 2003 Server. >>> Production environment.
My Plans:
1. On Testing Environment Install SQL Server 2000 cluster on Windows 2003 Server and do a restore of databases from the produciton environment.
2. Upgrade In-Place from SQL Server 2000 Cluster to SQL Server 2005 Cluster.
My doubts
1. Can i install SQL Server 2000 Cluster on Windows 2003 Server. Is it possible or not.
I am trying to upgrade a SQL Server 6.5(Cluster) to SQL Serevr 7.0 (Cluster)..I already have an intsllation of 7.0(On a Cluster),so this means that 6.5 and sql 7 are on seperate cluster's ,if i try to upgrade from 6.5 Cluster to 7.0 Cluster is asks me to uncluster 6.5 and 7.0 is this correct ,assume i cannot break the cluster then what???.. what is the best way i can achieve this functinality.....
Some of my customers ask for backup their databases, mainly MSSQL & MS Exchange. I search for any of backup vendor; there are 2 choices, service provider and software publisher. Service provider eliminates my technical support on backing up my clients databases:cool: ; software publisher offer a chance for me to create new business line:rolleyes: . What would your gurus prefer and why? Any admirable company you can name?

I have never applied a service pack to sql server 2000. Someone tells me that you have an option of supplying the SA password but do not have to and the service pack is applied just as if you did supply the SA password. This sounds odd to me. So, is it true? I am asking because our server instance shows "SP4" but a fix that was supposed to be included in SP4 was apparently not as the problem persists (link from sql server 2005 to 2000 fails when referenced in sql2005). I was thinking that whoever ran the service pack may not have provided the SA password so some of the SP4 was not applied???
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "s-1". The provider supports the interface, but returns a failure code when it is used.

Hello everybody, I'm new using ASP 2.0, I was trying to find out how do i tell a SqlDataSource the parameters it will be using for the select query. I was looking at the Configure Data Source wizard and when I press the where botton to create the parameters, I do not know how two of the available Source selections work which are: (Query String, and Session). What I want to understand is how do I pass the parameter value during the form load like I used to do with ASP 1.1. I used to write: during the pageload event: me.dataAdapter.selectparameter("@param").value = [myVar] me.dataAdapter.fill(Me.ds)
I tried to do something like this for the SqlDataSource but didnt work. can anyone tell me how can I acomplish this?
I am using SQL 2000 running a couple of large (up to 70GB) databases. I am currently backing up to disk, which is working fine. I now want to backup the databases using the Snapshot feature of my storage array. To do this however, I first need to put my databases (3 of them) into 'backup mode', so as to stop transactions being written to the database, and provide a consistent database to backup. Has anyone had any experience with this feature? Microsoft provide a sample C++ program called snaphot.cpp that puts a single database into 'backup mode'. I am not particularly clued up on C++. Can multiple databases be put into this mode simultaneously? Is this particularly difficult to do? Any help would be greatly appreciated
I am adding a file to a filegroup on a remote system, and i don't know the direcotry structure of that machine, how can i provide the path for FILENAME param. :eek:

I need to calculate the success rate of our OS Patch deployments. the data from system is stored in SQL with corresponding states (installed, missing, ...)
I would need to provide monthly report that shows how successful the deployment was for particular patchgroup. I have the following 2 dummy tables (just used as example)
table5 ==> Table containing patch groups + patches table6 ==> Table with machines names, patches and patch state
select * from table5 pgrouppatch GROUP1PATCH1 GROUP1PATCH2 GROUP1PATCH3 GROUP1PATCH4
[Code] ....
Result would be pgroup install missing group1 80% 20% group2 50% 50% group3 55% 45%
Ideally I would like to do this in T-SQL but if necessary can also do this in .NET Function. Only mention this but both Patchgroup and machines are dynamic each month can be different.
below are the sql scripts to create tables and populate with data
CREATE TABLE [dbo].[table5]( [pgroup] [varchar](128) NOT NULL, [patch] [nvarchar](128) NOT NULL ) CREATE TABLE [dbo].[table6]( [machinename] [varchar](128) NOT NULL,
