Performance Vs Fault Tolerance
Jul 10, 2001
We are setting up a new SMS (SP3) primary server with local SQL 7.0 (SP3) and are mandated to use the following configuration for hard drives:
C:&D: are on mirrored 18GB drives (2 channel RAID controller)
C: OS (8GB) partition
D: pagefile & temp (10GB)
E:&F: are on RAID 5 (3x36GB) 72GB useable (2 channel RAID controller)
E: temp data for field techs (10GB)
F: SMS & SQL (62GB)
We would like to have the SQL logs on a different physical drive than the data (for improved performance), so we are planning on putting it on drive D:
We realize this will affect redundancy, but should this be a big concern?
Has anyone used this type of configuration?
Pros, cons?
Any help would be appreciated.
Thanks
Brent

Hello All,
We have to setup a SQL 2000 box (it's what the app requires) and I would like to know what is considered the best practice for setting up the drive fault tolerance.
We are looking at allocating about 500GB for both system and data drives.
Thank you in advance for your input.
Sincerly,
Larry

Hi,
I'm using SqlServer 2000 at a web host, and share this db with about 200 others (it's an inexpensive web host so I guess there is not very much traffic on most of them, but I can only see their db IDs so I don't know what organisations they are or the urls they have).
Usually, my web site runs fine, but lately it's really really slow (as in non-functioning in reality). I'm in the middle of coding my seach functionality, so I fear that I'm causing this myself. ;-)
However, there are only ten posts in my test db, so it should be a piece of cake for SqlServer. The other .aspx pages runs rather slow too now, but when I start a programming session they have worked fine (this has happened three times now so I don't know what to conclude). When the server slows down, it can stay down for hours. I've also tried to access my site from other computers but get the same result, so I guess it has nothing to do with caching (I also tried emptying my browser's - IE7 - cache). I have several asp web sites with Access dbs at the same web host, and they all work fine. In addition, I have no problem viewing and editing my db at the web host via SqlServer Management Studio Express.
What do you think of this problem? Should I go for a more expensive web host? Should I give them the "It's not you, it's me" speech? ;-) Or is it really me?
Below's my search code, and as you can see, there are some integers there to make sure the loops don't run ad infinitum. I don't really think the problem actually lies with my search code, as everything worked well a week ago, but I don't know...
BTW, if you think my code can run much faster without getting too tricky, please let me know.
Please help!

Goodday all
I,m having a problem with something that worked well just recently. maybe I changed a setting by mistake.
I have a Database grid view on my page. When I configure my data sourse and get to "configure the select statment " on the wizard and press advanced to open the wizard with two check boxes " generate INSERT, UPDATE etc and the other check box "Use optimistic concurrency " this input box of the wizard is greyed out (non responsive)
Does anyone know how to rectify this?

Dear All,
I’m wondering if it’s the design that needs to be changed or I simply can’t put this together.
I have 3 tables.
1. people (peopId, peopFName, peopSName etc.)
2. codes (codeId, codeName)
3. codedPeople(codePeopleId, peopId, codeId)
Codes represent different skills of people, example the sort of job functions they’ve held in their employment. Like:
t-CEO,
t-CFO
t-Founder
etc.
people, clearly holds data about people.
CodedPeople holds data about which people are coded. So person1 can be coded as t-CEO as well t-Founder, and person2 coded as t-CFO
What I need is a query that returns all distinct people records and takes a number of codeNames as input. So if I throw in t-CEO OR t-Founder I get person1, again if I define t-CEO AND t-Founder I get person1.
However when I add t-CEO OR t-CFO I get person1 and person2 but when the query takes t-CEO AND t-CFO I get no result.
I can’t seem to come up with anything that would give me a good starting point. Is there a design fault here? All opinions are much appreciated, thanks in advance!

Hello there,
I've some really big problems with SQL Server 2005 Express. I Recently, I had 2 instances on my machine, one was a SQL Server 2000 Developer and the other a 2005 Express Version. The 2000 version was not necessary anymore, so I unstalled it, since then, the Express version keeps having probems.
Under the Server Properties -> Database settings -> Database Locations I've changed the path to D:sqldatamssql, but now, the programm always takes the "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData" to store and load the databases, no matter what I do.
And there are more problems see here:
Restoring does not work=======================
I wanted to restore a database called "fw40_admin" from a backup file (.bak), but that didn't work at all, it always says this as an error:
"System.Data.SqlClient.SqlError: The operating system returned the error '5(error not found)' while attempting 'RestoreContainer::ValidateTargetForCreation' on 'D:sqldatamssqlfw40_admin.mdf'. (Microsoft.SqlServer.Express.Smo)"
But as soon as I type in the installation path "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData" inside the "Restore As" under "Options", it works.
Why does the backup only work in "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData", BUT the database locations under the server properties is indicated with "D:sqldatamssql"????
Attaching does not work=======================
Attaching an existing database does not work either. Most databases (mdf) are located on the path D:sqldatamssql, but as soon as I press
Attach Databases -> Add
The dialog window appears with the "D:sqldatamssql" path, but it is unable to find any *.mdfs altough THERE ARE .mdfs in this directory. But Express can find databases in the selected installation: "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData".
Why can't Express see the directory on the D: partition???
What is wrong? Here? Can anybody help me?

Hi everyone:We received a error message "Log File to Database is Full. Backup thetransaction log to free up space."I have a Access 2000 application that calls a Stored Procedure thatinserts about 5000 records into a worktable on a SQL server 8.0database table. After the user is finished with the work table astored procedure deletes just the records that he was using in thework file (so I can't use Truncate Table). I have the work tablelinked to an Access database so I can't use a temporary table on theserver.This action of 5000 records being added and deleted to this workfilecan occur 7 or 8 times an hour. And for the last week I've beentesting the application so I have probably been doing this action 10to 20 times an hours.I do not currently use a COMMIT with the INSERT Stored Procedure orthe DELETE Stored Procedure.Although I didn't think this was a lot of records, could it be that myapplication caused this error. Is there a way to find out for sure ifmy application caused this error and if there something I can do in myapplication to keep the Transaction Log from filling up.Thank you for taking the time to read my post and any help would beappreciated.

Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***

We have the same application installed on a few different environments with similar servers and similar hardward. The only difference is the versions of SQL and the colations.
Is SQL 2005 a lot faster that SQL 2000? Could colation type make a big effect on performance?

What's my best bet in getting better performance out of one of my database servers? Currently we have 1 set of Raid5 disks partitioned into 2 drives. This houses everything (system, database, and logs) If that server has 2 slots left for drives I was thinking of putting 2 mirrored drives and getting the logs off the main database space? (Make sense?) This is a vendored application so working with new indexes etc. isn't something I should do wo/ the vendor's interaction. Will what I describe above help?

We have SQL Server running on a dual processor Pentium 500mhz server. Our database is hit by about 300 users. 200 of those users are doing constant searches though a client table of about 250,000 records, which in turn is linked to a history table containing over 5,000,000 records. This is only the tip of the iceberg, we have many triggers, procedures, updates, etc. going in the background. The database has over 500 tables.
Keep in mind, these searches that are taking place can involve all kinds of fields: phone number, company name, fax number, first name, last name, status, wildcard searches, etc. So as you can imagine, the database is being hit with all kinds of funky requests to find records. I will be the first to admit that our developers (vendor) are not the best code writers, and we have a tough time getting them to optimize something they do not even understand themselves.
As I speak, our processor utilization is maxing out between 95 to 100 percent. I've done a lot of performance tuning and all of the problems lie in the searching. We've built, tested, rebuilt, re-tested each and every index. I even used the Profiler to filter what I could. It has improved, but our database is growing at a rate of 10 megs a day (already close to 3 gigs, not that huge). I think I've optimized my indexes as best as I can considering all the fields and possibilities available to users to search for records.
For a database that requires all of these different search criteria, what would be a more optimal server? We are looking to purchase something ASAP. I could really use help from someone in a similar situation. It seems odd, in mind, that a company of 300 people would need to rely on a quad server (four processor capability.).
Thanks. JT

I am running a SQL 7.0 server on a two processor machine. We are having some performance issues.
one of the processor is always above 90% utilization but the second is barely at 50%.
Will adding another processor help or are the processes locked to one processor.
The server is a dedicated sql server. nothing else is running on it.
Thanks for any info you can provide.

Is there any option needs to set to improve performance? Now, SS 7 using all the 4 processors and dynamically allocated memory, etc. Any thoughts greatly appreciated.

I'm running MS SQL Server on a 1.4 GHz AMD Athlon Processor with 750 MB or RAM and ample disk space. I have a table with 14 columns; 2 datetime, 8 int and the rest are varchar of various sizes less than 13.
I run a java process on another machine that connects to the database and insert records. It takes about 6 minutes to insert 100,000 records.
I run the xp performance monitor and only about 25% of the SQL Server machine's cpu is being used. I run top on the Linux box running java and I see about the same results. Neither machine is kept busy processing. Why don't I get better performance? Could my local area network be that slow? How many inserts per minutes is good performance?
Thanks for your input.

Thanks for any insight on this. I'll try to look for white papers and do some testing in the meantime.

Hello,
I build a query in SQL-server 2000 but i'm not happy with the performance, it takes about 15 minutes to execute the query (4 min INSERT and 11 min UPDATE). The table tbl_total has 3 million records and an index on Contract and Item, the table contracts has 1 million records and a key on Contract and Item.
How can I speed up this query, is it for example possible to put an index on @table (internal table)?
Thanx in advance!
DECLARE @table TABLE (Contract nvarchar(15), Item nvarchar(12), Change_date datetime)
INSERT INTO @table
SELECT TOT.Contract, TOT.Item, MAX(TOT.Change_date)
FROM tbl_total TOT
WHERE EXISTS (SELECT 'X' FROM contracts CONT
WHERE TOT.Contract = CONT.Contract
AND TOT.Item = CONT.Item)
GROUP BY TOT.Contract, TOT.Item
UPDATE contracts
SET contracts.Change_date = TT.Change_date
FROM contracts INNER JOIN @table TT On
contracts.Contract = TT.Contract AND
contracts.Item = TT.Item
