Want To Load Balance And Cluster 3 SQL 2005 Servers

Oct 9, 2007

Currently we have a single SQL server. It went down and the higher ups were none to happy. Lots of money lost, down time, unhappy customers....the whole nine yards. They want to throw all sorts of money at the problem and want a solution that is high availability and provides load balancing. I think I came up with a solution.

3x Windows 2003 Enterprise Edition servers running SQL 2005 Standard in a cluster all connected to a SAN.

I'm guessing I need to set up Network Load Balancing in order to load balance the SQL database. What we would love to have happen is if one of the servers goes down, everything else just picks up. That coupled with our database that is increasing in size and transactions gets load balanced.

Am I going down the right path? Something else I should look at? Or that I am missing?

Thanks and sorry for posting this in multiple places!

SQL Clustering With Load Balance

Apr 18, 2006

For our application we are planning 4 Appserver/webservers with load balancing and 4 SQL servers in cluster with active/active setup. We are looking for some info on the active/active setup for SQL server 2000 Clustering.

1. Which cluster node replication method (2n, 2n +p or n+1) we should go for.
2. How operating system "windows 2003 server" should be configured and its role in failover.
3. How active/active failover setup for SQL Server 2000 really works and how much data loss happens in case of failover.
4. For web applications, how the session state is managed in SQL Clustering

I think this question has been asked number of times. However, I amlooking for some specific information. Perhaps some of you can helpclose the gap. Or perhaps you can point me towards right direction.Perhaps this group can help me fill in ms-sqlserver related followingquestions.1. Do this database have data Clustering capabilities?1a. If yes, what mechanism is used such as shared disk, share nothing,etc.2. Do these dB have Security features?2a. If yes, what security features are supported? For instance do theysupport encryption or SSL connection?3. How does the database perform and what is the criteria for theperformance matrix?4. Do they have inbuilt load balance capabilities?I want to thank everyone for taking your time to read thiscorrespondence. I will also greatly appreciate your efforts in sharingyour thoughts.Regards,Manish

SQL 2005 - Shared Load Cluster

Apr 26, 2006

Hi

This is more a product featuer question which I cant seem to find the answer to

If we wanted to share the loads of SQL Server requests over say 2 or 4 servers, is this possible?

What I mean is basically Active/Active load balancing / clustering? So we have one Virtual IP and all requests are forwarded to the least busy server.....

records from or into this table in less than one second.
i can't buy a very expensive hardware(Server) for this SQL Server 2005
but i can buy many medium price hardwares(Servers) for this SQL Server
2005.
how can i distribute or cluster this table between many hardwares(Servers)?
note: i have few users (maximum 5 users) for my database but i have a
very large table and Sql server 2005 server need to respond to this
users in less than 1 second.
i want to distribute this huge table in seperated hardwares. becuase i
can't buy a very expensive hardware from my server but i can buy many

SQL Server 2005 64bit SP2 Installation Issue On Cluster Servers.

Nov 23, 2007

Hi All,

We have been experiencing issues with SQL Server 2005 SP2 upgrade on cluster servers.
After running the setup, it gives failure message for Database services.

Installing SP2 on 64bit cluster server we get error regarding "passive node not patched properly or run the setup from passive node". However, select serverproperty(€˜productlevel€™) returns the output as "SP2". On more digging we found from SQL Server Error log, that the resourcedb of that server is of level 9.0.0.3199

€œThe resource database build version is 9.00.1399. This is an informational message only. No user action is required.€?

However if we do the SQL Server 2005 SP2 upgrade on standalone machines with the same software repository, it upgrades successfully and also resourcedb upgraded to 3042 version. So if we look at the errorlog of a standalone machine it gives following message.

"The resource database build version is 9.00.3042. This is an informational message only. No user action is required."

I again reiterate that, this is the issue we have faced on 64bit SQL Server 2005 SP2 upgrade only on cluster SQL Servers, however on standalone machine it works fine and 32bit SP2 installation works fine.

Please let us know the solution for this.

regards
Jay Mehta

[Q]SQL Server 2000 Cluster Load Balancing

Nov 8, 2001

Hey guys,

Lately we have come across a problem where our application is undergoing some extreme load against the SQL 2000 server database we have setup, where the server is hitting 100% CPU utilization each time. Currently the box is a 2 processor box.

Here is the question I have. I have seen under most SQL Server clusters that an active/passive setup is implemented. Where the passive server just exists as a failover mechanism. What I am looking for is some information on how to setup active/active setup where each server receives processes to handle.

Has anyone created a setup like this? Are there any standard benchmarking tools that can be used to see how this configuration increases performance? Is this setup more favorable than going to a 4 processor server as oppossed to our current 2 processor server?

BTW: We have noticed that after a web application where the user sits idle for a while the SQL Server application loses the connection with the application user...Is this the SQL Timeout causing the connection to disconnect?

Thanx for any response...

Using Cluster Servers And Preallocated Space

Mar 30, 2007

Hi All,

I am doing some design work on a new system. The plan is to use clustered servers accessing the same backend instance. I want to prepoulate the table with our unique id (for say 5M rows for sake of discussion). Where I am puzzled is how do I guarantee unique ids to the application when both servers are looking for the same next available row? The sql could be something like

select min(id) from table where user_id is null

The trouble our current system runs into is that there are occasions where the users generate the same id which of course messes up the application.


Is this a case where a store procedure would do the insert and return the id to the user is a better solution?

Thanks

Sep 27, 2007

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.

1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.

Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)

If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.

Thanks!

Upgrading A SQL Server 2000 Cluster To A SQL Server 2005 Cluster

Dec 28, 2007



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.

Thoughts?

Load Backup From 2000 To 2005 Or Recreate Structure On 2005?

Apr 23, 2008

Hello,

I would like to ask you if there is better to recreate database structure on 2005 from 2000 and move data or to just load
2000 backup.

Currently I loaded the backup, but I am wondering if there might be slightly better performance on 2005 when recreating structure on 2005 to loading 2000 backup?

Does loading 2000 backup create 2005 binary structure?

Thanks for help in advance

How To Balance The Database

Hello,

I started to use data mining sql server recently, and I have a little problem:

I'm trying to predict a boolean variable, but my database has only 1/4 of true results, because of that my predict probability is a little bit low in this kind of cases.

My question is: Is there a way of increasing the importance of a database entry in order to avoid editing a database with 40000 entries?

Thank you very much.

This is what acutally I am having in my stored procedure except the temporary table. The values which I am inserting here will get from my actual tables. What I need is to calculate balance. If you run this script you can see how the balance is calculating using the cursor.

I want an efficient way to calculate the same. I know cursor is not at all good option in stored procedures. Do you have any Idea to make this script in an efficient and simple way?

Running Balance Calculation - PLEASE HELP

Jun 23, 2008

Hi guys, I've really been struggling with this issue for quite a while and the solution still elludes me.
If anyone can help me I will worship you as a god for ever! [Wink]

The Scenario is as follows:
I have a table where several documents are linked to each other via a foreign key called ReconNum.
Basically this table is used to link Invoices, Credit Notes and Payments to each other.
Thus you get the following layout:

ReconNum LineID DocID DocType ReconAmount
111 0 101 Payment 20 000
111 1 202 Credit Note 12 0000
111 2 303 Payment 5500
111 3 404 Invoice 10 000
111 4 505 Credit Note 22500
111 5 606 Invoice 30 000
111 6 607 Invoice 20 000

What I need to do is assign values from each of the Payment/Credit Note documents to the Invoices. Thus getting the following result:

Inv# DocID DocType AmountApplied DocBal InvBal
404 101 Payment 10 000 10 000 0
606 101 Payment 10 000 0 20 000
606 202 Credit Note 12 000 0 8 000
606 303 Payment 5500 0 2 500
606 505 Credit Note 2500 20 000 0
607 505 Credit Note 20 000 0 0

I've come close, but it seems to be the old chicken or the egg problem.i.e. I need one field to calculate the other and vica-versa.
(Amount Applied, DocBal and Inv Bal are all dependant on each other)

NOTE: The only field I'm really interested in is the AmountApplied field, but amount applied depends on the DocBal and InvBal fields.

I need a running balance on both the Amount Due on the Invoice, and the Amount Availble on the document being assigned to the invoices. The problem is that I'm trhowing the data into a temporary table and cant use fields in the temp table for my calculation.
i.e. AppliedSum = if (Doc.Available amount on Doc < Invoice Balance) then Doc.Available Amount
elseif (Doc.Available amount on Doc > Invoice Balance) then Invoice Balance

Invoice Balance = Invoice Tot - sum(Applied Amounts)

Any help would be breatly appreciated!
