Query Perofroamnce Issues

All are telling for improving performance we have check st04/05 and rsrv? What we have to do here for improving performance? Pl expalain about OLAP Cache also and what are all we can maintain here?

Also look at
Frontend compression ( for web queries)
OLAP cache for queries
Precalculating queries using the Reporting agent.

Query Performance Issues

Hi Gurus,
I m woking on performance tuning at the moment and wants some tips
regarding the Query performance tuning,if anyone can helpme in that
rfrence.
the thing is that i have got an idea about the system and now the
issues r with DB space, Abap Dumps, problem in free space in table
space, no number range buffering,cubes r using too many aggrigates,
large IC,Large ODS, and many others.
So my questionis that is anyone can tell me that how to resolve the
issues with the Large master data tables,and large ODS,and one more
importnat issue is KPI´s exceding there refrence valuses so any idea
how to deal with them.
waiting for the valuable responces.
thanks In advance

Hi Amit
For Query performance issue u can go for :-
Aggregates : They will help u a lot to make ur query faster becuase query doesnt hits ur cube it hits the aggregates which has very less number of records in comp to ur cube
secondly i wud suggest u is use CKF in place of formulaes if any in the query
other thing is avoid upto the extent possible the use fo nav attr . if u want to use them use it upto the minimal level reason i am saying so is during the query exec whn ever there is nav attr it provides unncessary join to ur MD and thus dec query perfo
be specifc to rows and columns if u r not sure of a kf or a char then better put it in a free char.
use filters if possible
if u follow these m sure ur query perfo will inc

Either the statistics are not up to date, the data values are skewed or you have some optimizer parameter set to none default to force index access.
Please post explain plan and optimizer* parameter settings.

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html

Query Throttling issue after increasing List view threshold in connected webpart

Dear SharePointers,
I have connnected listview webpart deployed on site. Parent webpart
has 16 fields and over 3,000 listitems exists in list. Child webpart has 7 fields and more than 30,000 Items. The code works well in other sites in same web app and it also works well in other systems. We tested same in other system by increasing/decreasing
data but still we are not able to replicate issue. I know that this issue could also encounter if fields are not indexed in the list. Are there any other pointers which can use to debug this issue.

Hi,
According to your post, a Query Throttling issue occurred after increasing list view threshold in connected web part.
By default, this limit is set to 5,000 items for regular users and 20,000 items for users in an administrator role.
More information is here:
http://msdn.microsoft.com/en-us/library/ff798465.aspx
Please try to enable the Daily Time Window for Large Queries:
1.Go to Central Administration-> Application Management -> Manage web applications.
2.Select the web application that contains the large list.
3.Click General Settings, and then click Resource Throttling.
4.Under Daily Time Window for Large Queries, click to select Enable a daily time window for large queries.
5.Set a start time and duration when most of your users will not be working.
6.Click OK.

Query Performace Issue-Usage of SAP_DROP_EMPTY_FPARTITIONS Program

Hi Experts,
We are facing query peroformance issue in our BW Production System. Queries on the Sales Multiprovider are taking lot of time to run. We need to tune the query perofrmace.
We need to drop the empty partitions at the database level. Have anyone of you used the program SAP_DROP_EMPTY_FPARTITIONS to drop the empty partitions ? If Yes, Please provide me with details of your experience of using this program. Please let me know, whether there are any disadvantages using this program in the Production System.
Kindly treat this as an urgent requirement.
Your help will be appreciated....
Thanks,
Shalaka

Hi Shwetha,
I think that pgm drops if partition contains no records(in DEL_CNT)
or if partitions requid is not in dimtab (DEL_DIM)
Hope it helps!
(and don't forget to reward the answer, if you want !)
Bye,

Sql query cache issue

I am trying to see the log file in Manage sessions for the sql query in Answers. I see that if we run the same report multiple times, the sql query is showing up only the first time. Second time if I run it is not showing up. If I do a brand new report with diff columns picked it is giving me the sql then. Where do I set this option to show the sql query everytime I run a report even if it is the same report run multiple times. Is this caching issue?

It shouldn't.... Have you unchecked the "Cache" on the physical layer for this table? If you go onto the Advanced tab, is the option "Bypass the Oracle BI cache" checked?

BW 3.5, BEx Query designer issue with text of the characteristics

Hi All,
We are currently using BEx 3.5 Query Designer to design the queries. We have one of the ODS on which we are querying for.
We have 3 different types of Customer in this ODS. 0Customer, 0BBP_CUSTOMER and 0GN_CUSTOMER. The problem is when we open this ODS in Query designer we see their text name on the left hand side column where it shows data fields as the same text name Customer.
Now the our Power users have raised the issue that it is very confusing even when there are 3 different technical names for these characteristics.
2 Questions I have.
1) Why is something like this happening? is it some issue with the Patch or something. We will be migrating to new BI soon but in the mean time if I could resolve it that will be the best. Or does it even get resolved with new BI???
2) what is the way in which we can resolve it?
Thanks in advance and points will be given generously.

HI BI Consul!
Things like this happen, when it is called customer it could be different customers, 0customer is the standard R/3 customer and 0BBP_customer is objects from CRM and most likely 0GN_Customer might be customer from different system.
Sure, power users should be told which customer is customer and you could also change the discription of the object, to match the definition on the other system. You could also just create z object and replace the existing confusing object with something meaningful to users.
thanks.

******************

First off, be aware of the assumptions I'm making. The SQL you presented above strongly suggests (to me at least) that you have cursor for loops. If that's the case, you need to review what their purpose is and look to convert them into single statement DML commands. For example if you have something like this
DECLARE
    ln_Count        NUMBER;
    ln_SomeValue    NUMBER;
BEGIN
    FOR lcr_Row IN (    SELECT pk_id,col1,col2 FROM some_table)
    LOOP
        SELECT
            COUNT(*)
        INTO
            ln_COunt
        FROM
            target_table
        WHERE
            pk_id = lcr_Row.pk_id;
        IF ln_Count = 0 THEN
            SELECT
                some_value
            INTO

        END IF;
    END LOOP;
END;                            it could be rewritten as
DECLARE
BEGIN
    MERGE INTO target_table b
    USING ( SELECT
                a.pk_id,
                a.col2,
                b.some_value

                some_table a,
                some_other_table b
            WHERE
                b.pk_id = a.col1
           ) e
    ON (b.pk_id = e.pk_id)
    WHEN MATCHED THEN
      UPDATE SET b.some_other_value = e.some_value
    WHEN NOT MATCHED THEN
      INSERT ( b.pk_id,
                b.col2,
                b.some_other_value)
      VALUES(   b.pk_id,
                b.col2,
                b.some_value);
END;It's going to take a bit of analysis and work but the fastest and most scalable way to approach processing data is to use SQL rather than PL/SQL. PL/SQL data processing i.e. cursor loops should be an option of last resort.

Oracle 11g on Linux : Query Optimization issue

Hi guru,
I am facing one query optimization related problem in group by query
Table (10 million Records)
Product(ProductId number,ProductName varchar(100),CategoryId VARCHAR2(38),SubCategoryId VARCHAR2(38))
Index
create index idxCategory on Product (CategoryId,SubCategoryId)
Query1:To find product count for all CategoryId and SubCategoryId
select CategoryId,SubCategoryId,count(*) from Product group by CategoryId,SubCategoryId
Above query is not using index idxCategory and doing table scan which is very costly.
When I fire Query2: select count(*) from Product group by CategoryId,SubCategoryId
then it is properly using index idxCategory and very fast.
Even I specified hint in Query1 but it is not using hint.
Can anybody suggest why oracle is not using index in Query1 and what should I do so that Query1 will use Index.
Thanks in advance.

You could try the following to check the NULL issue:
select CategoryId,SubCategoryId,count(*) from Product where CategoryId is not null and SubCategoryId is not null group by CategoryId,SubCategoryId
Does this query use the index?
Can you show us the hint you've used to force the index usage and the EXPLAIN PLAN output of the two queries including the "Predicate Information" section? Use DBMS_XPLAN.DISPLAY to get a proper output, and use the \ tag before and after when posting here to format it using fixed font. Use the "Quote" button in the message editor to see how I used the \ tag here.
Are above queries representing the actual queries used or did you omit some predicates etc. for simplicity?
By the way, VARCHAR2(38) and ...ID as name, are these columns storing number values?

BI Query Authorization issue

Hi,
When a test user execute a query he is getting Insuffucient athorization
In RSECADMIN i executed as a test user and got the log
Please update me how to resolve the issue
No Sufficient Authorization for This Subselection (SUBNR)
Following CHANMIDs Are Affected:
17 ( 0TCAKYFNM )
Thanks

Hi there,
Regarding the 0TCAKYFNM "containing" information of all key figures, that's why I put the "", because this object doesn't contain anything, it is simply an InfoObject standard that SAP has with the flag marked in authorization relevant in transaction RSD1. This object exists for assigning key figures authorization used through the transaction RSECADMIN.
Even without the user notice, this object is checked against all the queries over all the InfoProviders.
If you go to transaction RSD1 for the InfoObject 0TCAKYFNM click on display on the Business Explorer tab you'll see the option AuthorizationRelevant marked. This will force the check for key figures assignment for all the queries against the authorization grnated through this object assigned to the user.
So if in this transaction RSD1 you change on the tab Business Explorer for this object 0TCAKYFNM and uncheck the AuthorizationRelevant, none of the key figures will be checked against the authorizations the users have to the InfoObject 0TCAKYFNM (since this InfoObject will no longer be authorization relevant).
If you leave the flag AuthorizationRelevant for the InfoObject 0TCAKYFNM as it is (marked), then in RSECADMIN as you did before, instead of granting * values (all values, all key figures) for the 0TCAKYFNM, you granted for instance the value 0QUANTITY and assign this authorization to the users, if this user executed a query with only the 0AMOUNT key figure he/she would receive lack of authorization, since he/she was only authorized to see values for 0QUANTITY key figure. So resuming, the values you assign for the InfoObject 0TCAKYFNM will be the key figures the user is authorized to see the query, and if you assing * it will be all the key figures (all values)
Hope this helps,
Regards,
Diogo.

Query Performance Issue based on the same Multiprovider

Hi All,
I am facing a performance issue with one of the BEx Query 1 based on a particular Multiprovider.
I have done all the kind of testing and came o a conclusion that the OLAP: Data Transfer time for the query is the max at around 820 Secs.
The surprising part is another Query 2 based on the same multiprovider runs absolutely fine without any hassles with OLAP : Data Transfer time with merely 3 Sec.
Another, surprise is that Query 2 has even more Restricted Key Figures and Calculated Key Figures but it runs smoothly.
Both the queries use cache memory.
Please suggest a solution to this.
Thanks.

Hi Rupesh,
There is no much difference between the 2 queries.
Query 1 - which has performance issue has the same filters as that of Query 2 - which is working fine.
The only difference is that the selection of Fiscal Week is in the Default Values Pane for Query 2 whereas its in Characteristics Restrictions in Query 1. I doubt whether this setting will have any effect on the performance.
Both restriction i.e Fiscal Week restriction is based on Customer exit and the rows include Hierarchy for both the queries.
I assume creating aggregates on hierarchy for the Cube can be a solution.

Using "Restrict by app" in change query causes issues with Search Results

Hello!
I am hoping some experienced SP admin can help me out. I am having issues with the relevance ranking for my search results web part.
I created a Wiki (OOTB) within a site collection and on the home page of the Wiki I was looking to apply a Search Box and Search Results web part for easy searching. I wanted to ensure the search results were restricted to the scope of the pages within the
wiki. I did the following after adding the 2 web parts:
Entered edit mode for the page
Started to edit the Search Results web part
Under Properties for Search Results clicked on "Change Query"
Navigated to BASICS and clicked "Switch to Quick Mode"
For Select Query, picked "Wiki (System)" option
For Restrict by app, picked "Specify a URL" and input the wiki URL "http://webapp.com/sites/sitecollection/wiki"
Click OK
The web part has 6 automatic results when I hit the page. These are the only 6 pages in my wiki. When I search a word or title of a page, they are not ranked in order or relevance. The ordering is static to what was being shown before the search, but the
keywords I'm searching are bold. With out the taking the steps above, I can easily search these pages and have them ranked appropriately so I'm not too sure what I'm doing wrong.
Other Details
The pages have been crawled and can be searched from anywhere else in SP.
I am only a site collection admin for this specific site collection.
I other than the steps above, I have not made any changes or customization to the search web parts; they are both out of the box SP.
The SP Farm admin we unable to pin point what the root cause is either.

Hi Mikael,
Sorry for the wait, I was unable to post pictures, which i felt would better describe my issue.
Could you output the query template you are ending up with?
If you can tell me how to accomplish this, then I can provide it. Please keep in mind that I am only a site collection admin.
Also, is the ranking/sorting for your webpart set to ranking?
When looking at the web part settings, I didn't see an option to modify the ranking. Unfortunately, some sites in my intranet are down now so I can't even double check. Once it's back up, I will verify this as well.
And how do you know they are ranked incorrectly?
I wanted to display an image showing what I meant by this. As the wiki is down, I'll do my best with words. When I visit the wiki home page, I already have the search and search results web parts there. Without searching anything, the search results
web part displays 6 pages that are available in the wiki. When I search, I expect to see the most relevant result at the top. similar to the following:
*Search result from another section of the intranet site.*
What I receive instead is the same list of wiki pages, in the same order. The most relevant result
is not moved to the top like in the image above, but I can see that the word "rush" is highlighted in bold. I hope this helps.
If you need more of a description, please let me know.
Thank you

SAP Query format issue (with ABAP list)

Hi All,
I had a requirement to remove all unecessary formatting and text from a SAP query report which can be read by a third party software system. We need only Header line and report data (spaced by Tab).
I have removed all formatting from the report and changed the output format from "SAP list viewer" to "ABAP list" .
The issue is that the report shows material number with 12 digits in output but when we download to file then it adds extra six "0" and makes the Material Number field as 18 digit.
we have already maintained new length as 12 againts the standard length 18 for material number(under field output option)
Please suggest how to get rid of extra digits generated during downloading.
Please help,
Thanks,
Rohit

Hi Brad,
Currently we execute query with SQ01 and from the output screen the user direclty saves the file as "local file..."
The output format is "abap list". We are able to get the exact format but the only problem is with material number. I cant make changes in the program. Is there a way to download it without changing the 12 character ( as displayed on the report output)
Thanks for help.
Rohit
