anyone use a 3rd party product to load balance SQL Server?

I'm working on a project needing a high-end large mission critical database
solution. The data is in 1 database. So SQL 2000 doesn't support load
balancing, and neither will 2005. That sucks. Oracle supposedly does load
balancing and I can't understand why even SQL Server 2005 won't do it. So
either I go with an 8+ CPU SQL Server or consider a 3rd party load balancer
that will somehow (?) make it work so that multiple SQL brains can balance
the load of 1 single database that is presumably shared on 1 set of disks.
I'm finding very little information on load balancing SQL Server when
searching the net. Is there a product like Legato, for example, (I haven't
tried it) that will somehow give me load balancing with SQL Server?HK wrote:

You may want to take a look at Federated Database Servers on SQL Server
2000/2005 if that architecture will work for you.

Creating the partitioned views sounds very challenging for an already-in-use
DB that needs to be cut over in the middle of the night. Plus ongoing
maintenance. Maybe I'm missing the boat, but that's why I'd want to stay
away from federated databases.

Anyone recently installed SQL Server 2000 Eval version

Hello,

I am having trouble installing Evaluation copy of SQL Server on my
notebook, which has XP, P4 processor,1G Ram, and 14 G harddisk space.

After I run the Setup.exe, I get the files files extracted in the
SQLEVAL directory.

As per the instruction, I need to run Autorun.exe file. For some
reason, when I try to run this file, a new windows pops up, which is
blank black screen with cursor flying around in the window. The title
of the window is
C:\windows\system32\wowexec.exe

This is how far I have reached while trying to install the database. I
would really appreciate if someone could provide some suggestions.

I have no idea what the problem is, but perhaps you could try running the
setup program directly - I think it's called setupsql.exe, in the \setup
folder (from memory).

Anyone producing a large number of reports per day?

I'm evaluting Reporting Services for my client. They need to produce 5000+
reports per day, mainly output in PDF format. The PDF's are 6-8 pages long.
Does anyone have any experience of getting this kind of performance out of
SQL-RS?
They have an 8-processor 2.8Ghz server running SQL Server that will be the
Reporting Services server. It has 4gig of memory. Will it be up to the job?
Thanks,
Andy.I am able to render about 70reports (PDF format) in less than 10mins. Each
report has about 200 pages.

of the memory.
To verify RS can handle this load, consider using a test tool like
Application Center Test (ACT), part of Visual Studio, to run a Proof Of
Concept. Below is sample ACT script you might use to run such a test:
' --

const ENABLE_DELAYS = True
const REQUESTBUFFERSIZE = 15000
const REPORTSERVERNAME = "localhost"
' --
' -- Think time variables - examples shows between 2-3 seconds
' --
const MIN_SLEEP_MSEC = 2000
const MAX_SLEEP_MSEC = 3000
' --
' -- Think time logic if desired
' --
Function RandomSleep()
if (NOT ENABLE_DELAYS) then
RandomSleep = 0
return
end if
Dim lMinSleep, lMaxSleep, lSleep
lMaxSleep = MAX_SLEEP_MSEC
lMinSleep = MIN_SLEEP_MSEC
' create a random int within our range
Call Randomize()
lSleep = Int((lMaxSleep - lMinSleep + 1) * Rnd(1) + lMinSleep)
' Test.Trace "Sleeping: " + Cstr(lSleep)
Call Test.Sleep(lSleep)
' return the delay time
RandomSleep = lSleep
End Function
Function SendGetRequest(reportServerUrl)

ANYONE PLEASE - Local Synchronization Between SQL Mobile and Local SQL Database

Hi Everyone

I am at the stage of architecting my solution

My goal is to develop the system on a windows application and pda

There is a central server which will create a publication called inventory

The laptops which host the windows application will be subscribers to the central server using merge replication

The client now wants the PDA using SQL Mobile to synchronize with the local subscirber database on the laptop using active sync. They dont want to do it via WIFI to the IIS Server at the central server

I have been reading for days and I am still unsure whether this is possible to do.

I know Appforge provide a conduit for palm to access synchronization but not local sql databases

I would appreciate your help immensley

Can anyone please help me

|||

If you build your mobile application using VS2005 and SQL Mobile, you can use merge replication between your server-side publication and SQL Mobile. The SQL Mobile Books OnLine are the first place to start - read the section on merge replication.

Hi Darren

Yes I got my sql mobile to synchronize successfully with the local desktop sql database called "Inventory"

However I have a new problem

I would like to have the desktop replicating with the server for database "Inventory"

I also got this to work seperately

I would now want the SQL mobile database to replicate with the local desktop database "Inventory" which inturn will replicate with the server copy called "Inventory"

I would like to have both replication scenarios joined together. I know that most people will say get the SQL mobile to talk directly to the server but this is the most expensive scenario I believe

Is this possible?

Thankyou for your earlier post

Touraj

Touraj,

Sorry for not reading your post more closely - I see what you are trying to do now. You want to have a 3 tier merge replication going on. Yes, this is possible, but the database on the laptop is going to have to be SQL Server 2005, not SQL Express. The way it would have to work is this:

The laptop would have to have IIS installed and the SQL Mobile server tools. As far as the mobile app is concerned, the laptop is the publisher. On the laptop, you have a subscription to the central server in a replication relationship. You would turn around and create a publication on the laptop with the same articles that are in the subscription to the central server. You would need to be extremely careful with uniqueness in this situation - I would avoid identity columns and use GUIDs for everything in this app domain.

Is there any chance that both the laptops and the PDAs can be subscribers to the central server? That would be a much easier implementation, but it is possible to do what you suggested with the extra tier.

-Darren

Hi Darren

Thankyou again for your kind assistance

Yes you are right. It would be easier and 'cheaper' to get the PDA to synch with the central server via the servers IIS process

I am tossing up between a i-Mate and iPaq 4700. I would be interested to know if you have a preference over the two

Thanks from sunny Australia.

Touraj

I think both i-Mate and HP make great devices - I have not had any trouble with SQL Mobile on my JasJar or on a variety of iPaqs. My WM5 JasJar seems a little sluggish overall compared to a Dell Axim X50v (WM5), which others have noted as well. Not slow, just not instant to respond to input. I have not had specific experience with the 4700. There are some public newsgroups (microsoft.public.pocketpc.developer) where people tend to talk more about specific devices and you could use Google Advanced Groups search to get previous opinions on the 4700.

anyone linked mysql?

has anyone been able to link mysql to sqlserver 2k?
i've gotten it to link and can see the tables, but all linked server
queries give errors because the mysql odbc apparently doesn't return the
right info needed for the 4 part name. after an extensive google
search, all i've found are people reporting the exact same problem i'm
having, but nobody has posted a solution.
i'm being forced to update mysql data and would much rather use my
stored procedures and scheduled jobs instead of scheduled dts packages.
We've seen the same thing, and never got it working. The ODBC driver for
mysql doesn't behave properly.
Sorry!
