Index Tuning : ReportServer DB
Nov 1, 2007
Hi All!
I would like to try and increase the performance of the reportserver database. Im thinking of adding an index to dbo.catalog.itemID - before I break the database and subsequently kill the 200+ reports i spent ages writing, does anyone know of any problems doing this?
The reports seem to be a bit slow first run but speed up during the course of the day - the server generates about 1500 instances of reports each day (7 instances of reportmanager all pointing to the reportserver db). I primarily use precompiled storedprocedures to feed the datasets so this is why im thinking index tuning may help.
Any thoughts/comments are welcomed!

I want to use the Index tuning wizard on some of my tables. Is it OK if I use when people are on the server or to do it during off-pick period. Thanks!!!

Other than the SQL Server 7.0 Index Tuner wizard (which isn't suggesting anything). Is there a 3rd party Index Tuner piece of software out there? Or is there something special that needs ot be done to get the SQL Index Tuner to work?

for what purpose we are splitting the non-clustered index into 3 instead of 1
create index si_acct_info_dtl_INDX1 on si_acct_info_dtl(account_code, ctrl_acct_type)
create index si_doc_hdrfk_ci_acct_info_dtl on si_acct_info_dtl(tran_ou, tran_type, tran_no)
whether index rebuit everycolumn when search is given????.if we build the index in one
statement like this:create index si_acct on si_acct_info_dtl(batch_id)
create index si_acct_info_dtl_guid on si_acct_info_dtl(batch_id,account_code, ctrl_acct_type,tran_ou, tran_type, tran_no)

Hi,
Our reporting tool dynamically creates tables and fields based upon Excel spreadsheets that are imported. To improve query performance, we are attempting to create indices on these tables automatically. The problem we are facing is that the tool allows the user to group the data by a whole range of fields when generating reports, therefore making it hard to decide what indices to create.
So, as an example, we have a table that has 10 VARCHAR(250) fields (the default size for text based fields in the tool), each of which could potentially be in the group by clause, and 15 numeric fields on which calculations will be carried out.
Is there a single index that we can create dynamically that would improve performance for all potential queries that may be generated? Such as an index that contains all the 10 VARCHAR(250) fields, and the numeric values as Included Columns?
If so, what effect does the order of the fields in the index have, ie we have some fields that have a lot of distinct values and some that have only a few. Which ones should appear higher in the list?
Any help would be greatly appreciated.
James

Is it possible to achieve Index tuning using sql script within Query Analyser when being just a db_owner and not sysadmin.
In case the answer is yes, would you please provide any link to help or examples.
Thanks

Hi,
I wanted to use the Index Tuning Wizard to monitor the performance of a stored procedure but the option is greyed out. Is there a way to turn this functionality on, or does this indicate that this option is not installed ?
Thanks,

I'm using the Database Engine Tuning Advisor to do some performance evaluation on my database. I have one particular table that will potentially have a couple million rows. but this may not occur for a few months to a year from now.
when i run the advisor with 1.5 million rows, it recommends that i add an index across all columns in this table (covering index) for an estimated 91% improvement. when i run it with 1500 rows in it, it recommends that i add an index on 2 key columns for an 8% improvement.
how should i reconcile this? can i have both and what does that do to performance?

HiI tried running ITW against one of our databases, and it came up with anumber of suggestions, but also filled the Application Log with messageslike:-The description for Event ID ( 4 ) in Source ( ITW ) could not be found. Itcontains the following insertion string(s):Error in Parsing Event:declare @P1 nvarchar(1)declare @P2 nvarchar(1)declare @P3 nvarchar(1)declare @P4 nvarchar(1)EXEC "dbo"."sp_get_RAO_indexW2K2" @P1 , @P2 , @P3 , @P4 .Does anyone know if this is serious (or indeed what it means at all)?There were no apparent errors in the ITW run.Chloe Crowder

HI
I have this complex logical model with 60 tables which i have converted to phycical model and into sql 7.0 database now the database is completely new for a new internet project without even single row of data now i have to optimise database and determine if the indexes created by the the designing team are good in sql 7.0 will the give me optimised database or not . I just dont know what to do
1) is it possible for me to use indextuning wizard without the data
whenever i try to to use indextuning wizard it askes me to use a workload file or make workloas file useing a trace as i do not have the data i just have to capture a trace by saying select * from <table>
as the work load file does not return any records the index tuning wizard does not suggest any changes In the indexing
tell me HOW DO I DETERMINE WHAT INDEXES TO CREATE FOR A OPTIMISED DATABESE ?
2) IT IS NOT POSSIBLE FOR ME TO PUT DATA IN ANY ONE TABLE AS ALL THE TABLES HAVE fk AND pk RELATION SHIP so what do i do
3) WHAT DOES dba normally do when he recives an empty data base to optimise
4) where do i make views to optimise the data
5) how do I populate data in so many tables
will puting dummy data help ?
Can some one help me with some SP which will populate the table with dummy data by some kind of do while loop with counter incrementing with 1000 rows
please help me
and if i am not clear
pl tell ask me the questions on my default email or

I've tried many times to get the index tuning wizard to work...It never seems to find any 'parseable queries' in my workload file. I believe that I'm running the profiler correctly.
When I submit a simple sql file as a workload file, I get a 'server error creating table or index analysis...' back.
Any suggestions or hints?
Thanks,
Steve

Hi
When I try to run the ITW to increase performance I get this error in the event viewer. Earlier I have used the ITW with success but now I dont get any more index recommendations, just this error. Do you know what it means :
"The description for Event ID ( 4 ) in Source ( ITW ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event:
Error in Parsing Event:

hello,
I'm looking for a way to populate my index on insertion but not on updates.
I tried each possible value for CHANGE_TRACKING MANUAL|AUTO|OFF and it automatically takes every changes that have been made before in account. is there a way to "flag" the rows that I don't want the server to re-index (i.e. updated rows).
Thanks for reading, any help is welcome.

Hello all.
I have the following table
Create Table Item(
I_AssetCode NVarChar(40) Primary Key NOT NULL,
I_Name NVarChar(160),
I_BC nvarchar(20),
I_Company nvarchar(20)
);
Create Index ind_Item_Name on Item(I_Name);
Create Index ind_Item_BC on Item(I_BC);
Create Index ind_Item_Company on Item(I_Company);
It is populated with 50 000 records.
Searching on indexed columns is fast, but I've run into the following problem:
I need to get all distinct companies in the table.
I've tried with these two queries, but they both are very slow!
1. "select I_Company from item group by I_Company " - This one takes 19 seconds
2. "select distinct(I_Company) from item" -This one takes 29 secons
When I ran them through the SQL Management Studio and checked the performance plan, I saw that the second one doesn't use index at all ! So I focused on the first...
The first one used index (it took it 15% of the time), but then it ran the "stream aggregate" which took 85% of the time !
Actully 15% of 19 seconds - about 2 seconds is pretty much enough for me. But it looks that aggregate function is run for nothing!
So is it possible to force the query engine of the SSCE not to run it, since there is actually no aggregate functions in my select clause?
According to SQL CE Books online:
Group By
"Specifies the groups (equivalence classes) that output rows are to be placed in. If aggregate functions are included in the SELECT clause <select list>, the GROUP BY clause calculates a summary value for each group."
It seems the aggregate is run every time, not only when there is an aggregate function.
Is this a bug?
Thanks in advance,
TipoMan
