Hardware Design Suggestion
Jun 4, 2007
I'm implementing a brand new project that consists in a soft-realtime application that executes scheduled operations (tcp commands) stored on a SqlServer 2005 express db. DB and app are always on the same workstation. Let's say that the workload is about 40000 events per day, with periods of activity and more idle periods. The DB is filled by external applications that provides insert/update using ad-hoc sprocs and providing only the 'preedceding event'. The major performance problem I see is given by the fact that each time an event is inserted the sproc must rebuild all the scheduled times (I've build an optimization that uses service broker as to update asynchronously the scheduled times). The application does not requires any special calculation and is very lightweight... it only fetches the db and sends tcp commands. The only 'hard work' is to guarantee the exact time for sending the commands.
Now I have to design the required hardware and I expect some tip from you on how to proceed to build a test workload and how to translate it into 'minimum hardware specification'. Consider that safety is not importand since system are redundant in other ways.
My questions are
- Should I put OS, tempdb, database and logs each on a separate disk array ? My idea is to have a two-disk RAID0 for OS and logfiles, and a n-disk RAID0 for tempdb and appdb
- How to extimate the number of disks to have in the RAID ?
- Should I also consider processor ? I have the idea that processor is not very important while I should pay attention to bus and memory bottlenecks: so I've thought to use DDR2 RAM with a FSB of 1066 MHz and a single dual or quad core cpu, so discarding XEON multiprocessor systems that requires FBDIMM, that AFAIK are slower that DDR2.
- any other suggestion ?

Hello,
I will have to create a table that consists of only of two main fields. one: them employeeID and two: the SupervisorID,
my question is what should I define as my primary key. Should it be an aditional field, or could it be the EmployeeID field.
The employeeID is an unique filed. The end user for this application will be updating rearly some of this records, and may be adding or deleting some new records exporadically.
Thanks for suggestions.

hi.. guys
one of my table has more than 300million rows. that i need to remove the data b4 may 2006 which is over 250 million rows. since the insert rate so high(none stop) and i cant truncate the whole table and dump the data after may 2006 back in (they wont let me). and if i use delete statment to delete only 200k rows data it will freeze up the whole database for long time(around 45 mins) and it will take me few months i believe. so that's not the option either.
is anyone out there got better idea?
also i got another table has more than 150 millions rows that index need to rebuild .... anyone got any idea how long it gonna take? just roughly guess. thanks

Hi,
We are plan to develop a new VB6 / MS Access application that will produce a whole bundle of reports for the outside salesman team (all of them have a laptop). The data is come from midrange AS400 tables.
Now we have decided should we using SQL Express with SQL tables or just MS Access MDB tables. Some of the laptop the salesman is only P3-800 and I'm worry about the speed for SQL express on those laptop.
The other hand, I like to use SQL databases, since we have the SQL server 2005 running for other application already.
Any one tested the performance between the SQL Express via MS MDB, it seems the SQL 2005 express is use more overhead than MSDE.
We tried the MSDE and the performance is not that great after the database grow beyond 500MB .
Any suggestion are welcome.
Thnaks!

We have SQL server 2005 as backend in our portal project.We have job search interface with below searchable fields
1.) City
2.)State --length 2
3.)Zip-- 5
4.)Keywords ( space or comma delimeted words)
5.)Category (Drop down List)
6.)Subcategory (Drop down List)
Based on the above fields we have 2 options to search and avoid performance related issues.
1.) concatenate all the above 6 columns into 1 column and apply a full text search. Fields like state & Zip will be appended with some delimeter to do a search on those particular values .
Ex : store the state "CA" as '#stCA#'. so that it will not search the rest of the data that has keyword CA.
2.) create a table with the above 6 columns and create a Full-Text search on all the columns.
Can you suggest us which one will best and why? If not any alternate better solution

I have a table that allows the scheduling of devices.
I can create an Insert Statement that allows a user to schedule a device as follows:
Device #1 From 5/1/08 To 5/30/08
Is there away to create a check that prevents the user from scheduling that SAME device for any days within that month?
Device #1 is NOT available to be scheduled anytime during the month of May because it is already scheduled.
Thanks for any suggestion.

Hi
I have a few tables which store classinfo, testsinfo, scoresinfo respectively.
For a given classID/TestID/CourseID i need to be able get the top 5/10/15 etc, avg, max, min of scores for reporting purposes.
I am wondering if i should maintain a seperate table which would be populated by a job daily and which would maintain the topper IDs rather than having a Stored proc return them dynamically when needed. I am looking for some suggestions. Please let me know.
Thanks.

I have some problem with ASP.NET cache, I found other people has similar problem, but I didn't find real solution.
The one bother me most is the SQLCacheDependency doesn't work stable. I insert object in cache and has SQLCacheDependency linked. After a period of time, it stopped working. That means the the object is still in cache, but change on db side doesn't remove the cache entry. I am not sure if it is ASP side or SQL side, I feel it is ASP side.
I am using 2.0 + SQL 2005.
Once the db command notification stop working, you have to restart IIS or clear all items in cache since you don't kno which one is changed.
Any suggestion?

Hai, This posting related to my previous posting. Updating Bulk record. Actully im writing SP for windows Services, which does bulk updating of records to Sql 2000.
In one point of time, i may recieve 2000 records for single update..So what i have done, im concatinating the values to be updated in string and passing the string..
But when i did the calcuation for 2000 records, the length of the character comes around 10000. So i cannot user Varchar to hold me concatinated value in SP. There is another datatype "Text" but im not sure abt that. For my requirment what is the data type can i go for.. if i can use "Text" how to declare that...Ordinary declaration gives me error..

Hi Friends
I required a suggestion from your side
Actually I am working in MS Access from last 6 months. Now I want to convert my database into SQL Server
I have a knowledge of SQL Server and I don't have any problem with this.
But what I want to know how to maintain a report in SQL Server I don't have any knowledge for creating a report. My freinds suggest me a Visual Studio 2005 for creating a Crystal Report.
So Please suggest me it is helpful or not and onething more is that I have to work on SQL Server 2000 or SQL Server 2005 which is more beneficial.
Please reply me for this
Waiting for your any kind of reply
Please
Thanks

I have noticed that the area of writing stored procedures for muti-user databases is a very specialised field and requires knowledge that's much more than the locking topics covered in 'online books' . I am sure there are some standard tips and tricks that are used in mutil-user databases for writing to tables. Most books have a chapter or two on locking, but I think this topic should be dealt with separately in a dedicated book to locking with extensive examples on locking. Does anyone know of such a dedicated book out there?

This is what I have:
Code:
Select
PR.WBS1,
PR.WBS2,
PR.WBS3,
PR.LongName,
PR.Name,
CL.Name as CLIENTNAME,
CFGMain.FirmName,
CFGMain.Address1,
CFGMain.Address2,
CFGMain.Address3,
CFGMain.Address4,
Contacts.FirstName + ' ' + Contacts.LastName as CONTACT,
isnull(LB.AmtBud, '0.00') as AmtBud,
Sum(LD.BillExt) as BillExt
From PR
left join Contacts ON PR.ContactID = Contacts.ContactID
left join CL ON CL.ClientID = PR.ClientID
left join LB ON LB.WBS1 = PR.WBS1 AND PR.WBS2 = LB.WBS2 AND LB.WBS3 = PR.WBS3
left join LD ON LD.WBS1 = PR.WBS1 AND PR.WBS2 = LD.WBS2 AND LD.WBS3 = PR.WBS3 And LD.BilledPeriod = '200408',
CFGMain
Where (PR.WBS3 <> 'ZZZ') and (PR.WBS2 <> 'ZZZ')
Group By PR.WBS1, PR.WBS2, PR.WBS3, PR.LongName, PR.Name, CL.Name, CFGMain.FirmName,
CFGMain.Address1, CFGMain.Address2, CFGMain.Address3,
CFGMain.Address4, Contacts.FirstName, Contacts.LastName,
LB.AmtBud
Right now I have a column that takes the sum of LD.BilledPeriod when equaled to '200408'. The problem is that I need to include another column that also calculates the sum for BillExt where LD.BilledPeriod <= '200408'. Ordinarily I would have done a subquery which I have tested and it does work. But, I have to find another way of doing this because when I add subqueries other functionality in the software I using does not work. So, I am hoping that someone might know another route for me to take. I was thinking about using a UNION but this will not create a new column that I need.
Thank You,
Laura

FROM LedgerAR
WHERE (WBS1 = '001-298') AND (WBS2 <> 'zzz') AND (WBS3 <> 'zzz') AND transtype = 'in'

12230
90013271.02
Id there a way to specify where I want this exact amount to display without having to a subquery. I would ideally like to take the 3271.02 and put it where wbs2 = '1217'
Any suggestions?

Hi Everyone,
I'm looking for some suggestions on how I can go about the following task. I have an application which connects to our SQL2000 servers. Ocasionally some of the db connections take a long time to run. What I'd like to do is enable some sort of logging which would provide me with the following pieces of information... where the request originated from, length of time servicing the request, some sort of info on the nature of the request (search, insert, update, sproc, etc...), time of the request.
I'd then like to cross reference these logs with my application logs to isolate which requests are taking to long to service. Hopefully this will help us as we attempt to eliminate the issue.
Thanks for any suggetions you might have!!!! much appreciated!

Please answer following questions?
1-Before installing microsoft cluster+SQL Virtual Server I should install normal installation of SQL2000 on both nodes.
2-I have 8x72 GB Ultra320 SCSI in MSA1500 storagebox. What is your recommendation how should I make drives and which RAID system for quroum,DB (db is almost 5 to 10 GB), and T-Log should I use?
3-I have only one database instance, so still I should configure MSDTC or no need?
4- Can I use the same drive and cluster group for Quorum and MSDTC?
5-On windows 2003 when SQL virtual server will finish installation. Then the SQL SP4 I should install on one node or I have to install it one by one on all nodes of the cluster.I am using Active/Passive scenario.
Pls reply my questions.Then I will start my projetct.....

My question is anyone has run into this problem, and how do you solve it?

Am I on a right path? I will greatly appreciate in any comments or suggestions for a design. I am creating an n-tier application and i don't know if my design is right. I dont have the proper schooling for creating this kind of applications and I am still on layer of data access and business logic.
