Boost SQL Server Priority On Windows 2003
Dec 8, 2005Hi,
I've noticed declining performance on our main accounting server. We have a Windows 2003 server running SQL 2000 Enterprise and 8 GBs of RAM.
Has anyone used the "boost SQL Server priority on windows" before? If so, were there any major benefits in using it?
This server is excusively used for SQL btw...
Thanks,

To Boost Performance
Apr 1, 2006We are designing the database for a high load web application.
We used 4 techniques.
1.No outer joins,No Unions, > only in reports
2.No joins in main forms
3.Choose the smallest dataTypes possible.
4.Used a single instance for all users.
Are there any additional MAJOR ones?

May 5, 2006Hey, I'm using PHP with MSSQL, and I'm not having any performace problems or anything, but at the same time I'm trying to optimise our system to work as best as it can as it's going to have a very heavy load once we launch.
I'm running into the age old problem with the battle between optimizing your code and still keeping it readable. I read somewhere that using whitespace in SQL queries is really bad as it take a lot more bandwidth and puts more stress on SQL Server parsing the SQL it is sent. Right now I have a query like so:-
<?php
$selQ = 'SELECT
n.pknewsID AS newsID,
n.title,
n.full_text,
n.publish_up AS datePublished,
CONCAT(u.fname," ",u.lname) AS author,
i.loc AS img_file,
i.descr AS img_caption
FROM tblnews n
LEFT JOIN tblusers u
ON n.fkcreated_by = u.pkuserID
LEFT JOIN tblnews_images i
ON i.fknewsID = n.pknewsID
WHERE
n.pknewsID = '.$articleID.' AND
n.published = 1
LIMIT 1';
$selQ = $DB->setQuery($selQ);
/**
* $DB->setQuery basically is a preg_replace function that
* removes all the tabs in the query string, and replaces them
* with a single space.
*
*/
echo $selQ;
/**
* Printed out it looks like this :-
* SELECT
* n.pknewsID AS newsID
* n.title
* n.full_text
* n.publish_up AS datePublished
* CONCAT(u.fname," ",u.lname AS author,
* i.loc AS img_file,
* i.descr AS img_caption,
* FROM tblnews n
* LEFT JOIN tblusers u
* ON n.fkcreated_by = u.pkuserID
* LEFT JOIN tblnews_images i
* ON i.fknewsID = n.pknewsID
* WHERE
* n.pknewsID = 6 AND
* n.published = 1
* LIMIT 1
*
*/
?>
So the question I have is, does it really matter how the SQL query is sent? I mean, if I put it all on one line (which would kinda suck as it is harder for me to read then), would it speed up transactions significally?
Tables Partitioning -- Performance Boost
Nov 13, 2007Hi
I have a question about the partitioning a table.
I have a database with more 50 tables and 25 tables are having more than 10 lakhs records which includes history records.I have two data files for this database under PRIMARY FILE GROUP.Now i want to transfer these history records to some other database.
I wanted to know if this kind of activity will boost the database performance?.If yes how should i configure my new database.
On what factors of partitioning my performance will boost.
Thanks in advance

Can Partitioning A Table Boost My Performance?
Sep 28, 2007I have an existing database with a table of about 50 milion records. There are also about 20 other tables, but they are alot smaller. The large table has a uniqueidentifier as it's Primary key (not sequential) and a forien key to a 'parent' table. The table also has a column telling when it was created. So, a bit simplified, it looks like:
ChildTable
---------------
Id uniqueidentifier <PK>
ParentId uniqueidentifier <FK>
CreationDate DateTime
ParentTable
-----------------
Id uniqueidentifier <PK>
CreationDate DateTime
Most of the questions accessing the Child table (the large table) is doing so by referensing the parent table, and not the CreatingDate, i.e.
SELECT *
FROM ChildTable
WHERE ParentId = '......'
All records with a specific ParentId will have very similiar CreationDates.
Now, my question is, will Partitioning the ChildTable boost performance for me? In case it will, what column(s) would define the Partitions? If I do it by CreationDate, a select-query like the one above will have to scan all partitions anyway, doesn't it? Doing it by Id isn't soo easy either I guess? If it helps, it might be possible to change the primary keys in the tables to have sequential guids.
Is there perhaps a performance tool to get help with suggestions about how to partition the table? Something like the 'Performance dashboard' reports, but for partitioning?

Priority Of Databases
Mar 8, 2004Hi,
Is it possible to change/set the priority of databases? (Win2K, SQL 2K)
We have an evnironment which is somewhat lacking in resource, and would like to place the priority of one of the databases lower than the other so that the processing on the main database is carried out before the secondary one.
If there isn't any way to do this for the database level - is it possible for a specific user?
Hopefully I havnt been too vague here - but if there is any more info I should be passing on let me know.
Thanks in advance.

Task Priority
Jul 19, 2006Hi,
In my Sequence container task, I have 3 data flow task ( one data flow task is based on the constraint option Expression). 3 are running simultaneously, is there a way to assign a priorty which one should finish first before the other starts.
If I make all of them in one sequence then the conditional task come in between which may stop the execution of the 3rd task depending upon condition.
Please Guide.
Set Priority On T-sql Statement
Feb 11, 2008Hi
We are in the process of moving some data from one structure to another. The complete script takes very long time to complete in out production environment.
The script can maybe filtered even more, so it can run in small steps. The only problem here is that we would like it to be transactional.
But i came to wonder - are there any way to tell before starting a t-sql statement that it should run with low priority? This way it could run for 2 days, without having any severe impact on the production environment?
Best regards

Set Priority For Queries For Certain Users
Jul 31, 2000Is it possible in SQL Server to set the priority at which a query will run
for certain users. I have some users who's queries I never want to
take over the database. These queries may take 10's of mintes to complete,
and will slow down the server and affect the performance of more important queries. Is there a way to keep this from happeneing?

Dec 3, 2007
Not sure if this is the forum to post this question to - if there's a more appropriate forum please let me know.
I have a SQL Server 2005 box which gets accessed in two ways - an application with it's own login and sprocs which get accessed through reporting services with its own login. What I've found is that the application will get timeouts on its queries when people are running reports which use time intensive sprocs (> 1 minute to run).
Is there a way to give a particular login a higher priority so that it won't timeout when other logins access these sprocs?

Setting CPU Priority In Stored Proc
Oct 29, 2007Hi all,
I have a stored proc. which is going to run 3 days long. So , i was looking for some setting (or) priority , which i can set in the stored proc.
so that, if someone else is using the server, they should get high CPU Priority, and my process ( Stored Proc) should remain in suspended state, until CPU & Disk activity is low.
Note : The only way others are getting affected is because of hardware resources, because nobody is using those tables which is being used by STORED PROCEDURE.
Can anybody tell plz, how to achieve this.
Thanks.

Stumped On How To Set-up Priority So Evaluation Correctly Finishes
Feb 2, 2008Hello everyone
Here is the situation I'm trying to set-up a package to ftp some files down if that part fails email me but if successful rename the 2 files to something else.
so what I set-up was a FTP tasks with the remote path set as a expresion since I needed to Download todays files.
no problem there have that part working.
so then I set a notifaction event with failure constraint to email me. pretty easy so far.
then I set 2 tasks to rename the 2 files downloaded I'm sure I could do this part with a loop but what seperate tasks so I knew if any failed or could set-up notifaction tasks if I wanted. in the 2 rename tasks I set the sourcepath to an expression so it would know to read todays files and they could change from day to day.
then the destination part is hard coded for now to a file name.
now here is were the issue comes in I go to save it and it says the files don't exist from the rename piece. well of course not they haven't been FTPed yet.
so I tried delayevaluation on both the file system tasks but a no go still errors.
What I need it to do is basically say wait till the ftp is run these files won't be there. any help in the right direction would be appreciated.
thank in advance

Controlling Process Priority In SQL Server 2000 - Possible..?
Jun 25, 2007A similar question has been asked in a different thread, but didn't get a conclusive answer. Is there a way to set process priority on a specific process (alternatively - processes started by a specific user), similar to what the Task Manager allows in Windows?
I need to archive some data from an OLTP database. Unfortunately, some of the tables are growing rather large, and copying the data, and especially removing it based on record age, is a resource-intensive operation. My database must be available 24/7, and I can't have queries timing out, or I start losing business real fast. I was thinking of firing off the archive script and setting the process priority on it to something lower than normal, so it won't interfere with my OLTP processes.
Maybe someone can suggest a better solution?
Adjusting The Priority Of The Replication Process (SQL 2000)
Oct 5, 2006Hi,
I need information on adjusting the priority of the replication thread(s) within SQL Server 2000. All I've been able to find is how-to's on adjusting the priority of the SQL Server process itself, as well as information on how to adjust the relative priority of changes made to the database by subscribers.
Here's the situation, from time to time our replication system goes down, it starts itself up after waiting 5 minutes but this causes a problem. When its starting up it seems to be taking up far too many CPU cycles. As such the server is unable to process SQL queries, which forces its subscribers to time out. This is a bad thing as the subscribers are control systems on an assembly line. What I want to do is lower the priority of replication so that the server can still process queries while the replication agent is restarting itself. Is this possible? If so how can it be done?
Thanks,
Geoff Dupuis
