I am running a Desktop SQL 7.0 database on Windows 95. I produced a trace file using the Profiler and am trying to run the Index Tuning Wizard on the trace file. I always get an error message "Error analyzing workload (60).". I cannot find anything in Books Online or the Microsoft web site.
Thanks for any help.
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,

hi all,
jusr read about index tuning wizard in BOL.. not sure about it enuff.. can anybody explain in what scenario we should use this wizard/

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
View 1 Replies View RelatedI'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?

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:

Hi,I am having problems getting anything useful out of the index tuningwizard.I have created a table and inserted data into it.

Just curious if anyone has a script to find and delete all indexescreated by index tuning wizard, leaving the original indexes untouched.All of the original indexes in this particular database are precededwith IX_, whereas those created by ITW are the table name followed by anumber.I'm thinking of something along the lines of "sp_MSforeachtable@command1="print '?'" + a DBCC which just targets the ITW indexes (ifsuch a thing exists). Any ideas how to go about this?

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.

Eveytime I feed a query into the Index Tuner
I get the usefull message Error analyzing query (60)
What is it and how do I get round it
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
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?
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!
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

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

By default, the Upsizing Wizard
transfers all indexes as nonclustered indexes. You can modify the Upsizing
Wizard to transfer the primary key index to a clustered index. To make this
change, start Microsoft Access and open the upsizing wizard library database.
For Microsoft Access 95, the filename is Wzcs.mda. For Microsoft Access 97, the
filename is Wzcs97.mda. When the database is open, click the Modules tab and open the
UT_ModUserConstants module. Search down to the UT_CLUSTERED constant. Change
the default value from False to True.
<<< end quote
Question: I am using ACCESS 2002 upsize wizard, I searched my computer for *.mda and could not find any wzcs*.mda. How do I set it so that it creates clustered-index instead of non-clustered-index?

Hi All,
I have become frustrated and I am not finding the answers I expect.
Here's the gist, we support both Oracle and SQL for our product and we would like to migrate our Clients who are willing/requesting to go from Oracle to SQL. Seems easy enough.
So, I create a Database in SQL 2005, right click and select "Import Data", Source is Microsoft OLE DB Provider for Oracle and I setup my connection. so far so good.
I create my Destination for SQL Native Client to the Database that I plan on importing into. Still good
Next, I select "Copy data from one or more tables or views". I move on to the next screen and select all of the Objects from a Schema. These are Tables that only relate to our application or in other words, nothing Oracle System wise.
When I get to the end it progresses to about 20% and then throws this error about 300 or so times:
Could not connect source component.
Warning 0x80202066: Source - AM_ALERTS [1]: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
So, I'm thinking "Alright, we can search on this error and I'm sure there's an easy fix." I do some checking and indeed find out that there is a property setting called "AlwaysUseDefaultCodePage" in the OLEDB Data Source Properties. Great! I go back and look at the connection in the Import and .... there's nothing with that property!
Back to the drawing board. I Create a new SSIS package and figure out quickly that the AlwaysUseDefaultCodePage is in there. I can transfter information from the Oracle Source Table to the SQL Server 2005 Destination Table, but it appears to be a one to one thing. Programming this, if I get it to work at all, will take me about 150 hours or so.
This make perfect sense if all you are doing is copying a few columns or maybe one or two objects, but I am talking about 600 + objects with upwards of 2 million rows of data in each!!
This generates 2 questions:
1. If the Import Data Wizard cannot handle this operation on the fly, then why can't the AlwaysUseDefaultCodePage property be shown as part of the connection
2. How do I create and SSIS Package that will copy all of the data from Oracle to SQL Server? The source tables have been created and have the same Schema and Object Names as the Source. I don't want to create a Data Flow Task 600 times.
Help!!!
I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Hey,
SQL Server 7.
I have a view which joins 3 tables. One has 15 million rows the next another 5 million and the third 500k.
When I join them the execution plan tells me that 15 million rows were retrieved from the first (taking about 5 mins) 1.5 million from the 2nd taking 3 mins and 4.5 million from the third taking almost no time.
The first two ause a clustered index, one being a seek the other a scan and the third a regular index seek. All followed by a hash match/inner join which takes 2 mins.
Any ideas on optimizing the SQL?
Here is the syntax:
SELECT b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr, c.gst_inc,
SUM(a.credit)
FROM TABC c INNER JOIN TABB B
ON b.PACKNO = c.PACKNO AND
b.COMM_DATE = BENDTL.COMM_DATE AND
b.BEN_NUM = c.BEN_NUM INNER JOIN
TABA a ON b.tran_id = a.tran_id
WHERE b.tran_date > '20040401' AND c.gst_inc = 0
GROUP BY b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr,
c.bendtl.gst_inc
I tried on finding out the problem in a slow running sp with profiler. I found that there are some waiting resource 'tracewrite' and 'async_network_io'. Any idea on it? Thanks in advance

Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

Hi,
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Any ideas as to what is causing this error?
