Key Factors For Efficiency Of SQL Server 2000 (performace Tuning)
Apr 18, 2007
Hello All,
I am new to SQL Server 2000. I am eager to learn what factors/parameters are key for obtaining good retrieval performance of SQL Server 2000 (prompt response to user query).
I recall that someone told me that a recordset with asOpenStatic cursor type has higher speed than that of a recordset with other cursor types.
Is this true or false. Are there really some key parameters for perfomance tuning .
Thanks

Hello
I have a VB6 application using classic ado (MDAC 2.8) for connecting ms sql 2000 server. Application uses a lot of server side cursors. Now I want to switch to ms sql 2005 server but I have noticed very serious performance problem. Sql profiler results of execution of following commands:
declare @p1 int
set @p1=180150131
declare @p3 int
set @p3=1
declare @p4 int
set @p4=16388
declare @p5 int
set @p5=22221
exec sp_cursoropen @p1 output,N' Select ... from ... where .... order by ...',@p3 output,@p4 output,@p5 output
select @p1, @p3, @p4, @p5
on sql server 2000:
CPU: 234
Reads: 82515
Writes: 136
Duration: 296
and on sql server 2005:
CPU: 4703
Reads: 678751
Writes: 1
Duration: 4867
Both databases are identical, the servers runs on the same machine (Pentium 2,8 Ghz, 2 GB RAM) with only one client connected. On forums I've read that Microsoft doesn't recommend using server side cursors on sql 2005 but is there any way to increase performance to some acceptable level?
thanks in advance

Hi,
I have two servers that i want to create a SQL RS report on.
On one server there is an HR database with our staff details, on the other server there is a database of assets.
In order to report on the assets assigned to each user i am thinking that i will have to :
1) link the servers
2) create a view in the HR database exposing the fields needed
3) create a view in the assets database exposing the assets information joined to the view from the other server
4) create my reports on the view on the assets server.
is this right or am i barking up the wrong tree?

I have a scenario in which a schedule is recorded like the top table below. Notice the start and end times, the meeting length, and the fact that you could book more than 1 meeting (book factor) during the times slot. The second table is the result needed. I have it working using the dreaded cursor, but I know there's got to be a more elegant solutions.

bookFactor

I'm currently working on a project at work to test the effects of database compression, trying to obtain measurable data on the impact of the compression on other server resources, and therefore whether the reduction in space used is worth the extra overhead. This has involved taking a trace of a production customer's workload for a period of time and replaying it against a backup using Distributed replay in synchronised mode.
I'm then taking a trace of that replay, as well as using perfmon to record useful data about the server, before and after compression is enabled. Finally, I'm loading the traces into a tool called Qure to analyse the impact of the compression on reads, writes, CPU, overall duration etc.
What I'm finding is that even across 2 different 'baseline' runs, which are replaying the exact same workload against the exact same database, performance etc differs to a significant enough degree that it calls into question the validity of the test. I can only put this down to the fact this server is on a VM, which is affecting available resources, which in turn affects execution plans the workload is generating and causes different replays of the same workload. I'm therefore looking at doing this on a standalone server, but I still can't be sure the differences will go away.
How to make tests such as this as similar as possible on multiple runs, when elements outside of SQL Server are in effect out of my control?

Can anyone give me some guidelines as to when to chose JOINS over returning multiple resultsets in a strored procedure..
For eample, I have two tables, Orders and OrderDetails, which are linked by a primary key field. There can be orders w/o a corresponding record in orderdetails.
1.) I can return all orders and their details using a stored preocedure that has:
SELECT o.order_id as OrderId, o.customername, od.order_id, od.orderdate FROM orders AS o LEFT OUTER JOIN orderdetails AS od ON (o.order_id=od.order_id)
2.) I can do the same by returning two results sets in a different stored procedure:
SELECT order_id, customername FROM orders
SELECT order_id, orderdate FROM orderdetails
I think the client processing time for the second option will be slightly less, because the resultset I need to filter will only be as big as the orederdetails table (it will not include records for orders that have no details). Regardless, I think this would only make for a small performance gain, so if Option 1 is better in Database performace, I would probably go with that.
I assume the method to choose also depends on table size and # of JOINS. Any guidance would be appreciated. Thanks,
Al

I have a openquery query like this
Select * from openquery([db2],'Select * from tableA')
To only return and process records for a given date range I changed it to be something like this
Select * from openquery([db2],'Select * from tableA')
where datefield > '06/06/2001'
While this works fine, my question is that does it copy all the records from the db2 server to the sql server before filtering them. I think it does.
The db2 table will have over 1,000,000 records eventually, and the sql server will use records for a given day/date range only.
I cannot add the where clause to the db2 query.
any ideas ?

I have tried many things and even the worst case thing which I was trying to avoid i.e. uninstalled MSDE SP3 and Analysis Services and service packs but the problem is still not solved...
Whenever I open a DTS in design view and double click on the link (the line connecting the two) between the source and destination servers the PC goes to sleep and comes back after a long time and then the same problem occurs when I press on the transformation tab...
I know this may sound weird but that really is the case :o
Any clues anyone .... please

and TCP as a connection method.
When using Named Pipes the issue is no longer there.
On massive batch inserts we sometimes get a long pause at the end of one insert and before begining the next one. Example:
1000 inserts in the same table and then repeat. This will work fine for 3 or 4 iterations, then pause during the 5th iteration for up to 40 seconds and then simply continue.
When this exact same procedure is done using Named Pipes as the connection method this never happens.
While this is happening neither the server or the workstation is doing anything, 0% CPU, 0% network, it just sits there.
All this using the SQL Native Client 2005 and ADO.
Anyone have any ideas?

I created two tables one is based on partition structure and one is non-partition structure.
File Groups= Jan,Feb.....Dec
Partition Functions='20060101','20060201'......'20061201'
I am using RIGHT Range in Partition function.
Then I defined partition scheme on partition function.
I have more than 7,00,000 data in my database.
I checked filegroups and count rows. It works fine.
But When I check the estimation plan time out for query it is same for both partition table and non partition table.

Situation: In this stored procedure, I have to calculate in some manner: Font, FontSize, BoldText, ShowBox and number of characters to see how many lines it will take on a Crystal Report. Wondering if you have seen some like this on Web or have an ideas? Measurements(length, width) and character count seem appropriate. How about a function?
Uses Arial and fontsize can be 8pt - 28pt.

Hi,
I am with the response time for a simple count on a fulltext search that is too slow.
Even using the most simple query on a good server (64 bit Dual Opteron 4GB Ram with high speed 16 raid disk storage)):
select count(*) from content_books where contains(searchData,'"english"')
Takes 4 seconds to count the avg 500.000 resultsI have removed all the joins with real table data so that the query is only inside the fulltext engine..
I would expect this to be down to 4 milli seconds. Isn't it just getting the size of the "english" word result index?
It seems the engine is going through all the results because if a do a more complex search that returns less results the performance is better.
Any clues of how to do this faster? I never read the thousands of records BUT i need to count them...
Thank you very much.

Hi,
I just upgraded my sql2000 server (3gb Ram,2 x2.4ghz p4xeon processors) to sql2005 64 bit (4gb ram,1 x dual core 2.0 xeon processor) The single processor is supposed to be faster than the previous dual processors combined.
The problem is now I am having major performance problems, the queries are lagging pretty badly intermittently.
What steps should I take to resolve this? I am planning on upgrading to 8gb of RAM tonight or tommorow as a 'throwing hardware at this problem without really knowing what I'm doing approach.'
I am not very good with perfmon, but if you want any stats from there please let me know. I'm googling now what I should be checking for.
I can't figure out why its actually running worse, these problems got worse after I set a maintenance plan to run last night which did backups, reindex all the stuff etc... It failed after 2 hours and I woke up to horrible performance this morning.
Any help much appreciated!
Thanks,

I am looking to improve the performance of my sql server databases.
I currently have a dual location system, the database server setup is basically a quad xeon with 4gb at my office and a double xeon with 4gb at a remote webhosting location. There are separate application/web/intranet servers at each site. The two databases servers are replicated with the local server publishing to the remote server.
The relational database holds circa 26 million records, growing by a volume of 10,000 per day, there are approximately 50,000 queries performed per day.
My theory is that the replication of the two databases is causing a slowdown; despite fast network connections (averaging 200ms between servers) the replication seems to place a large load on the local server. Would it be sensible to replicate to a second local server and then replicate to the remote server, placing any burden on the second server?
I am planning to upgrade the local server to a high capacity 4+ cpu 64bit server, my problem is that although I have noticed a slow down in performance over time, I am unsure how to go about measuring and quantifying this in order to diagnose the bottlenecks and ensure that investing in a new server would be worthwhile. Where would one be best advised to start this project?
