Analysis and Performance tuning of a query

Hi gurus,
We have few reports built on multiprovider (which is containing five basic cubes) whose response time is very slow, so i want to do some analysis to find out why they are runing very slow and also do the performance tuning.
So where do i start and how do i start like is it from Report or multiprovider
if its report or multiprovider please kindly guide me what are the things do i need to look for and how to correct them whether adding something or changing the data design.
i have four reports
1. is runing on three basic cubes
2. is runing on all the five cubes
3.& 4. runing on 2 cubes
so kindly give your inputs
thanks and regards
Neel

Regarding Indexes and performance tuning.

Hi Everyone,
I need some elaborate explanation about indexes and performance tuning.
1. How do you find out whether the select query which I write is utilizing the indexes .
2. Is it true that the sequence in which the indexes are defined in se11
for eg: MANDT
KNUMH
KOPOS
your select query should also have the same sequence in the where clause else the indexes are not utilized well .
3. Is there any precautions/ special method to write select queries for proper utilization of indexes.
Thanks to all reading and answering in advance.
Rgds,
Anu.

Hi
You will find like this
If your select like this
select matnr mtart from mara into<itab>
where matnr = <>..
Go to table and see mara ..if matnr is checked as primary key,then you are using primary index.
Check secondary index tab and see if any fields,if those fields you are using in select then you are using secondary index.
2.Not sequence,check how many fields are checked tick as primary key,all thsoe are index.
3.Always try to use proper primary index in select statment and avoid nested select statements.
Thanks

What are the best practices for Database management and performance tuning?

Hello,
I want to ensure that I am using the best practices for managing and maintaining our Database.
Is there any documentation out there that outlines how to maintain and ensure top performance out of our database?
Thank you!
John Sefton

I appreciate the responses, however this is not the information I am looking for.
I am specificaly looking for best practices invloving the managment and performance tuning.
Example: are their tools that I can install that will monitor the size and response time of the database and alert me if there is degradation in performance?
Are there specific periodic activities I should be doing to garuntee that my database will continue to function that way it is supposed to?
Or is this a fire and forget solution that does not need this attention?

Calculating the memory and performance of a oracle query

Hi,
I am now developing application in java with oracle as a back-end. In my application i require lot of queries to be executed. Hence, the system is getting is slow due to queries.
So, i planned to develop one Stand-alone application in java, that should show the statistics like, memory and performance. for ex:- if i enter one SQL query in the text box, my standalone application should display, the processing time it requires to fetch the values and the memory is used for that query.
Can anybody give ideas, suggestion, etc etc...
Thanks in Advance

Performance tuning for JCDS query

Hi All,
I have a performance issue in following query.Any Idea how can it be improved?
    SELECT objnr udate utime
           FROM jcds
           INTO TABLE it_jcds
           WHERE objnr LIKE c_or
            AND   stat = l_tj02t
            AND   cdtcode LIKE c_co
            AND inact = space.

CHGNR                                        319
Is 'like' statement causing the performance issue and how can it be corrected?
Or Index can be created for this?

You can try this: Create 2 ranges, for objnr and cdtcode and fill like:
ra_objnr-sign = 'I'.
ra_objnr-option = 'CP'.
ra_objnr-low = 'OR*'.
append ra_objnr.
ra_code-sign = 'I'.
ra_code-option = 'CP'.
ra_code-low = 'CO*'.
append ra_code.
SELECT objnr udate utime
FROM jcds
INTO TABLE it_jcds
WHERE objnr IN ra_objnr
AND stat = l_tj02t
AND cdtcode IN ra_code
AND inact = space

Performance tuning for ABAP Query (created from t-cd SQ01)

Hello all,
We created ABAP Query report from transaction SQ01.
But the generated report has an appropriate SQL statement which causes performance problem.
To solve this issue, I guess the easiest way is;
0. Give up to use it.
1. Copy it to another object in the customer namespace.
2. Ajust SQL statement.
But I'm wondering if there're appropriate ways to adjust SQL statement of Query.
Could anybody give me any better idea?
Thank you

Performance tuning in SQL query using join of views

Hi,
Am trying to tune a query of the format
select ........ from view1,view2
where view1.keyfield = view2.keyfield
The base tables of the views view1 and view2 have indexes specified on 'keyfield'.
However, when I do an explain plan of the query, Full table scan of those base tables are performed.
Even tried using Hints in this query to force Oracle to use those indexes, but still not successful.
Any pointers on how to tune this kind of query would be highly welcome.
Regards,
Baish

If your query is really of the same form as you posted, then full table scans then a hash or merge join may be the most efficient plan.
You are asking for all of the rows from view1 and the matching rows from view2, because of this, Oracle dedcided that the cost of full table scans using multi-block reads is cheaper than using single block reads to get the rowids from the index, then single block reads to get the rows from the table.
FULL SCAN <> BAD

Performance tuning on a query

I am working on fine tuning below query.
SELECT SEGMENT1
FROM MTL_SYSTEM_ITEMS
WHERE ORGANIZATION_ID = 100
AND INVENTORY_ITEM_ID = :a
MTL_SYSTEM_ITEMS have 8 million records. This query is in a function that gets called probably a million times a day.
What I am thinking to do is to create a view on mtl_system_items table where organization_id = 100. Now if I use the below view, do you think the query will execute faster?
SELECT SEGMENT1
FROM MTL_SYSTEM_ITEMS_VIEW
WHERE INVENTORY_ITEM_ID = :a

Check your numbers of parsing for these particular query after each execution.
e.g,
SQL>SELECT * FROM(
2 SELECT parse_calls*executions Product, parse_calls Parses
3     ,executions Execs, sql_text FROM v$sqlarea ORDER BY 1 DESC)
4 WHERE ROWNUM <= 50
5* ORDER BY parses DESC
SQL> /
   PRODUCT     PARSES      EXECS SQL_TEXT
   2608960        155      16832 SELECT apl_dnum ,COUNT(*) "Numbers" ,SUM(q3d_amount) "Amount" ,ddate FRO
   7661664        111      69024 SELECT COUNT(*)   FROM Q3_LODGMENT_DTL WHERE APL_DNUM = :b1
   1412853         51      27703 SELECT ZONE_DESC_SHORT   FROM ZONE_STP WHERE ZONE_CODE = :b1
50 rows selected.If yours session_cached_cursors parameter have the capibilty to caching more SQL statements per session then it will reduce re-parsing.Though bind variables in
SQL code reduce parsing.
Check yours index exist,check out yours network flow,yours DBA gave you very nice job but there is no hard and fast thumb role to identify exactly what causes to degrade this specific query.

Business Process Management - End-to-End Analysis and Performance KPI's

Hello,
I am from WB and were looking to expand our footprint with Business Process Monitoring.
For critical business processes (order to cash, release to accounting, procure to pay; create shopping cart, etc.) how can be map and determine for the business units the expected run times as well as capturing / reporting historical trend analysis; looking at from a company business process level and not an SAP transaction level.
We were disappointed that we were unable to find this detailed functionality in SolMan (dashboards, metrics, customizable reports, etc.) that could tell us how long a WB business process takes to execute form start to finish.
Does anyone have any info as to if NetWeaver BPM can capture and trend the complete A-Z run times of a Business Process?
Iu2019m I missing something here?! I would think something this basic would automatically be a part of SolMan BPM Monitoringu2026
Appreciate all and any feedback.
Thanks!

tblSession : ID,option1,option2,option3,option4,option5,option6,option7,option8,option9.
tblOption : ID, labelID
tblLabelDetail : ID, LABELID, text
optionID 1 to optionID9 are Foreign keys to table tblOption.ID
My query is as below :

Is there a way , where i can simplify the joins with tbloption and tblLabelDetail and get my o/p in optimal time.
Regards

I have headed towards another approach ie. using unpivot and then pivot.
First i am converting option1-option9 into column , then doing PIVOT to get back the same record . But issue is that when i am doing pivoting i am getting NULL values.
My query is :
select * into #t1 from
select ID
, option1
, option2
, option3
, option4
, option5
, option6
, option7
, option8
, option9
from vCustomConsumer
where sid=105
and sessionYM = 1412
) SourceTable
UNPIVOT
optionID FOR Col IN
(option1
,option2
,option3
,option4
,option5
,option6
,option7
,option8
,option9 )
) AS unpvt
select t.ID,t.optionID,t.col,cast(ld.text as varchar(max)) as text into #t2
from #t1 t
left outer join tbloption o on o.ID = t.optionID
left outer join tblLabelDetail ld on ld.labelID = o.labelID and ld.langID=1
order by ID,col
select ID,option1
,option2
,[option3]
,option4
,option5
,option6
,option7
,option8
,option9
from
select ID,optionID,col,text
from #t2
)up
pivot
min(text)for col in
(option1
,option2
,[option3]
,option4
,option5
,option6
,option7
,option8
,option9
)as pvt
In my last query where i am using pivot, i am getting NULL values. When i check the data in temp table #t2 , it exists perfectly . But when pivoting i dont understand why it is returning most of the NULL values. I am getting data for only one column in single
row.
Below are some rows from result set finally obtained after pivoting :
ID
option1
option2
option3
option4
option5
option6
option7
option8
option9

Issue with performance tuning of a query

Hi,
I have a query which is in the below format
select a.* from
(inline query) a,
(inline query b)
where a.id = b.id;
Now i want the inline query b to be executed first and then joined with a.
How can i achieve the same.
Let me know if more information is required.

h4. NO_MERGE - This will allow inline query executing first
h4. LEADING(b) and USE_NL(b a) - We want to make driving table as "b" and then nest loop with "a"
SELECT /*+ LEADING(b) USE_NL(b a) */ a.*
FROM   (SELECT /*+ NO_MERGE */ LEVEL ID FROM dual CONNECT BY LEVEL <= 100 ) a,
       (SELECT /*+ NO_MERGE */ LEVEL ID FROM dual CONNECT BY LEVEL <= 10 ) b
WHERE a.id = b.id;

Performance tuning in Query

Dear All,
My client wants to do the performance tuning in a query where it has the Global structure of 300 CKF & 300 RKF.
They dont want to touch the MP, all they want to do some performance tuning through the front end without touching the Multiprovider.
The CKF is little bit tricky where in Each CKF has 28 RKF and In each RKF atleast 2 variables are used an with hierarchy restrictions. The query is taking 30 - 40 min to execute. Kindly guide me how to handle this.
Regards,
Suman Thangadurai.

HI,
Improving query performance u2013
-     Generate index.
-     Build query on multiprovider and better use Constant Selection Function to bring infoset functionality to Multiprovider.
-     Make your query more dynamic using variables.
-     Do partitioning on IC when you have restriction on 0CALMONTH.
-     Use more free charecterstics.
-     Use include than exclude at Bex level.
-     Utilize Cache mode and Read mode functions.
Regards,
rvc
