Reg : Performance Issue in Report

Hi All,
I need Some our ideas to reduce my performance in an program for the below scenario,
i have two internal tables say for example i1 and i2.
i1 has 30,000 records.
i2 has 2,00,000 records.
now i want to find out whether that 30,000 records exists in the 2,00,000 records for that i have written a piece of code as follows,
loop at i1.
loop at i2 where matnr = i1-matnr.
if yes
appending.
endloop.
endloop.
am getting the output but it's very time consuming it takes more than 20 minutes.
Is there any option to compare internal tables without looping even i use read instead of second loop it does the same.
Can any one suggest me how to make a performance faster.
Regards,
Suresh.

Sorry am not aware how we can reduce the performance of program!! there is lots of way to reduce the performance.
i know only about increase the performance of any program.
sort :
i1 by matnr,
i2 by matnr.
loop at i2.
read table i1 with key matnr = i2-matnr binary search.
if sy-subrc = 0.
appending.
endif.
endloop.

Using Reference Cursor Performance Issue in Report

Hi,
Are reference cursor supposed to be faster than a normal query? The reason why I am asking is because I am using a reference cusor query in the data model and it has a performance issue on the report, it's taking quite a while to run than If I just run the same reference cursor query in sql*plus. The difference is significantly big. Any input is very much appreciated!
Thanks,
Marilyn

From the metalink bug 4372868 on 9.0.4.x. It was fixed on 10.1.2.0.2 and does not have a backport for any 9.0.4 version.
Also the 9.0.4 version is already desupported. Please see the note:
Note 307042.1
Topic: Desupport Notices - Oracle Products
Title: Oracle Reports 10g 9.0.4 & 9.0.4.x
Action plan:
If you are still on 9.0.4 and later version of oracle reports and have no plan yet to migrate to 10.1.2.0.2 version use the same query you are using in your reference cursor and use it as a plain SQL query in your reports data model.

Performance issue with report

Hello
i am making a change to an existing custom report.I have to pull all the orders except CANCELLED Orders for a parameters passed by user.
I made a change as FLOW_STATUS_CODE<>'CANCELLED' in rdf.The not equal is causing performance issues...and it is taking lot of time to complete.
can any one sujjest what will be the best to use in place of not equal.
Thanks

Is there an index on column FLOW_STATUS_CODE?
Run your query in sqlplus through explain plan, and check the execution plan if a query has performance issues.
set pages 999
set lines 400
set trimspool on
spool explain.lst
explain plan for
<your statement>;
select * from table(dbms_xplan.display);
spool offFor optimization questions you'd better go to the SQL forum.

Performance issue webi report-BOXI3.1

Hi,
We have a requirement for a report where we will give user a set of objects (26 u2013 31) to do analysis using interactive viewing feature. Here we are facing severe performance issues and memory issues as the data that we are calling is huge( around 6 million records). At the report level we will be summarizing the data.
No of rows in the report is depending on the no of objects.
Mode of view : Interactive view.
Note:
1. Objects which are using in conditional level those have indexes.
2. No of report level variable are two.
3. Version of Business objects: BOXI3.1
4. OS: Sun Solaris
Please let me know if there are any means by which the memory requirements for the report can be minimized/ performance of the report can be improved.
Thanks,
Subash

Subash,
At the report level we will be summarizing the data ... any means by which the memory requirements for the report can be minimized/ performance of the report can be improved
Is there any way that you can summarize this on the database side versus the report level? The database should be sized with memory and disk space properly to handle these types of summarizations versus expecting the application to perform it.
Thanks,
John

Performance issue in report programming..

Hi,
I am using one customized Function Module whithin a loop of internal table containing fields of PROJ table for about 200 records . And in the source code of function module there is set of select queries for different tables like COSS COSP , AUFK , PRPS , BPJA PRHI , AFPO , AFKO etc . so due to that my performance of a report is very low , So how can i improve it .
Is there any other way to change a code.
regards
Chetan

Hi John ,
I am using SAP ECC 6.0 .
The report is used to update a ztable which is already created for Project System plan data .
So i am calling function module which will return a internal table , I am appending this to other internal table and refreshing it , like this I am doing for each project within a loop of PROJ internal table , finaly by using the final itab I am modifying the ztable fields.
Code is as below..
select pspid from proj client specified into corresponding fields of
          table t_itab1 where mandt = sy-mandt
                          and pspnr in s_pspnr
                          and vbukr = p_vbukr
                          and prctr in s_prctr.
loop at t_itab1.
    l_pspid = t_itab1-pspid.
CALL FUNCTION 'ZPS_FUN_BUDGETS'
      EXPORTING
        L_PSPID       = l_pspid
        L_VBUKR       = p_vbukr
      TABLES
        T_DATA        = t_itab2 .
loop at t_itab2.
      append t_itab2 to t_itab.
    endloop.
    clear   : t_itab2.
    refresh : t_itab2.
endloop.
LOOP AT t_itab.

Performance issue of report

Hi Friends,
Can you please give me the exact answer for the below question.
Suppose my report program is taking long time to execute, what are the reasons that may effect the report.
and what are the remedies should i follow, please provide appropriate answer.
Advance thanks,
Chandra.

hi,,
Go to tranx SE30 here you will get Tips and Trciks for the performance tuning.
Check it carefully and check whether you can do something for improving performance of you code.
It will help you a lot and will reduce your Execution time.
If you are using READ TABLE command in your program then you can check whether you can use HASHED TABLE it will improve performance of your code a lot but it has some restrictions.
I will explain some of the points to improve the performance of the report try to write code according to that ok.
SOME STEPS USED TO IMPROVE UR PERFORMANCE:
1. Avoid using SELECT...ENDSELECT... construct and use SELECT ... INTO TABLE.
2. Use WHERE clause in your SELECT statement to restrict the volume of data retrieved.
3. Design your Query to Use as much index fields as possible from left to right in your WHERE statement
4. Use FOR ALL ENTRIES in your SELECT statement to retrieve the matching records at one shot.
5. Avoid using nested SELECT statement, SELECT within LOOPs.
6. Avoid using INTO CORRESPONDING FIELDS OF TABLE. Instead use INTO TABLE.
7. Avoid using SELECT * and Select only the required fields from the table.
8. Avoid nested loops when working with large internal tables.
9. Use assign instead of into in LOOPs for table types with large work areas
10. When in doubt call transaction SE30 and use the examples and check your code
11. Whenever using READ TABLE use BINARY SEARCH addition to speed up the search. Be sure to sort the internal table before binary search. This is a general thumb rule but typically if you are sure that the data in internal table is less than 200 entries you need not do SORT and use BINARY SEARCH since this is an overhead in performance.
12. Use "CHECK" instead of IF/ENDIF whenever possible.
13. Use "CASE" instead of IF/ENDIF whenever possible.
14. Use "MOVE" with individual variable/field moves instead of "MOVE-
CORRESPONDING", creates more coding but is more effcient.
Reward points if helpful.

Performance Issue Crystal Report and Oracle

Hello,
We have one procedure that takes 3 input parameters and returns Cursor from Procedure that is used to design the report. There is no caluculation involved here and cursor is opended dynamically. We are using Oracle Native connection.
When we click on preview button it takes lots of time ( >10 Mins) to show complete data. While we call the same procedure in application and generate HTML report using Cursor returned it is done in < 15 Seconds. Can some point me where to look into to improve the performance of Crystal Report.
DB: Oracle 10G
CR: Version XI

Hi Vadiraja
The performance of a report is related to:
External factors:
1. The amount of time the database server takes to process the SQL query.
( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
2. Network traffics.
3. Local computer processor speed.
( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
4. The number of record returned
( If a sql query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
Report design:
1. Where is the Record Selection evaluated.
Ensure your Record Selection Formula can be translated in SQL, so the data can be filter down on the server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
2. How many subreports the report contains and in section section they are located.
Minimise the number of subreports used, or avoid using subreports if possible because
subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100 records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest factor why a report takes a long time to preview.
3. How many records will be returned to the report.
Large number of records will slow down the preview of the reports.
Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report off a Stored Procedure, or a Command Object that only returns the desired data set.
4. Do you use the special field "Page N of M", or "TotalPageCount"
When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page of the report before it displays the first page, therfore it will take more time to display the first page of the report.
If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't use when you view a report it only format the page requested.
It won't format the whole report.
5. Link tables on indexed fields whenever possible.
6. Remove unused tables, unused formulas, unused running totals from the report.
7. Suppress unnecessary sections.
8. For summaries, use conditional formulas instead of running totals when possible.
9. Whenever possible, limit records through selection, not suppression.
10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports. SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
11. Using one command as the datasource can be faster if you returns only the desired data set.
It can be faster if the SQL query written only return the desired data.
12. Perform grouping on server
This is only relevant if you only need to return the summary to your report but not the details. It will be faster as less data will be returned to the reports.

Performance issue - Pricing Report

Hi Experts,
I have developed an ALV report and I need to improve the performance in production.
I have a relatively complex issue here. I have to fetch data for pricing from a pricing condition from all the respective underlying condition tables (AXXX). Then for every material, I have to display the material class classification characteristics and their values maintained in the material master as well as batch classification characteristics and their corresponding values maintained for every batch.
For example:
In this way, if the condition is having 10 materials, every material has say 10 material class characteristic and 12 batch class characteristics then the total number of rows in the out put should be 130 (one for material and 12 rows for classifications).
How can I optimize the output so that the performance is optimized.
I am also fetching other data for the output like stock and sales order quantity against every material.
I have tried minimizing loops and used select for all entries(I have read a few threads which suggests otherwise). Read statements use binary search. No select * queries.
Warm Regards,
Abdullah

I would not sign a lot of the recommendations going around here. Seems like a complex report you are doing there, so here is my personal generic recommendations:
- always use index when selecting from database tables
- avoid redundant database accesses to unbuffered tables, only read fields you really need for processing
- use sorted or hashed tables for reads or loops and access them by key
- use ASSIGNING rather than INTO when reading or looping (small gain)
- use SE30 and if necessary ST05 to fine tune if not yet satisfied with the runtime

Performance issue for Report Regions

We have an app which has as it's "Home Page" a portal-style page. The "portlets" are separate regions. Some of these regions are HTML forms, but most are report regions, invariably with PL/SQL returning the SQL query.
On our dev box this portal renders fine, in no more than 5 seconds (acceptable). On the production box a couple of the portlets go crazy, usually taking between 1-2 minutes each. I know this because I added the #TIMING# string to each region footer. The portal page has a META tag to refresh every 120 seconds.
The first thing I did to debug was to take the PL/SQL function body returning the SQL query, replace all the variables (which are just local vars, app items and page items) with hardcoded values, strip all quotes and run the "cleaned up" SQL query in SQLPlus. It executes very fast.
So my conclusion is that the problem lies with the application server (which is Oracle iAS). Is this a logical conclusion? What should my next move be to get to the bottom of this?
Even without the problem portlets the portal refresh speed varies widely, between <1 sec and >10 sec.
The application also has other pages displaying the portal regions individually. These pages (including those with the "problem portlet" queries) render ok (ie, order of 5 seconds or less). This tells me that there is an issue with having a bunch of query-based regions on the same page.
My guess is that I might need to examine the logs and/or httpd/modplsql settings of the app server. Number of simultaneous connections?
What would happen if hundreds of users used this app concurrently, navigated to the portal page and left it like that to auto-refresh every 2 minutes? Are such pages a no-no in HTMLDB?

Some more information:
When I run the page in debug mode, I see the following timings for one of the problem portlets:
11.53: show report
11.54: determine column headings
11.54: parse query
60.95: binding: ":F118_BUNDLE"="F118_BUNDLE" value="1"
60.95: binding: ":P52_STMETRICS_PRODBRANCH"="P52_STMETRICS_PRODBRANCH" value="RDBMS_MAIN"
60.95: binding: ":P52_STMETRICS_PLATFORM"="P52_STMETRICS_PLATFORM" value="LINUX"
61.35: print column headings
61.35: rows loop: 15 row(s)
[report is printed here]
61.49: FORMITEM: P52_STMETRICS_PLATFORM HIDDEN
61.54: FORMITEM: P52_STMETRICS_PRODBRANCH HIDDEN
This tells me that the bulk of the time (50 seconds in this case) is eaten up in parsing the query. What is this symptomatic of?
Another problem I've just noticed. It takes about 5 seconds to open up a region for editing (Region Definition) in HTMLDB. When I click "Apply Changes" (even without editing anything) it is taking on the order of minutes for the changes to be applied to the page. Our app server was bounced just before I noticed this.

Performance issue with report server

we have recently migrated our application from c/s 6i to 10g web (Oracle AS rel 10.1.2). when we are running one balsheet report it was taking about 16-17min to complete running in web. We are using rwservlet to run this report. to my annoyance the same report when run in c/s environment (with same parameters) takes hardly 1min to complete running. The report has 10 pages in all. what we have observed from em console is that that it formats first 5-6pages of the report in just 150-200secs but later for other pages it is taking lot of time. we have even tried out using jvmoptions but that did not help me either. I request any one of you to suggest me as to what can be done at the application server level so that i can acheive the performance of the c/s version report. I am novice to oracle reports and any help is highly appreciated.

We seem to have fixed the problem of hanging/slow reports by configuring the init.ora file and changing the optimizer_mode to FIRST_ROWS_10. We set the workarea_size_policy to AUTO too and reports sped up significantly, I don't know the exact changes because our DBA's did them but I think the optimizer was the key change.

Performance issues in reporting side

hi gurus,
   how to improve performance in reporting side.

Hi kumar,
Query Performance Techniques:
1.     Check Query propertiesUse RSRT tcode
2.     Check whether cube is compressed
3.     Optimize query definition
4.     Analyze query execution
5.     Check for additional indexes
6.     Archive unwanted data
7.     Check for partitioning options
8.     Check for additional aggregates ( Consider DB ratio and KPI ratio)
9.     Check for parallelization options
10.     Use Nav attributes instead of hierarchies, use free char and filters.
Possible causes for the performance :
A) High Database Runtime
B) High OLAP Runtime
C) High Frontend Runtime
Depending upon your analysis
A)Strategy - High Database Runtime
Check if an aggregate is suitable (use All data to get values "selected records to transferred records", a high number here would be an indicator for query performance improvement using an aggregate)
Check if database statistics are update to data for the Cube/Aggregate, use Tcode RSRV output (use database check for statistics and indexes)
Check if the read mode of the query is unfavourable - Recommended (H)
B)Strategy - High OLAP Runtime
Check if a high number of Cells transferred to the OLAP (use "All data" to get value "No. of Cells")
a) Use RSRT technical Information to check if any extra OLAP-processing is necessary (Stock Query, Exception Aggregation, Calc. before Aggregation, Virtual Char. Key Figures, Attributes in Calculated Key Figs, Time-dependent Currency Translation) together with a high number of records transferred.
b) Check if a user exit Usage is involved in the OLAP runtime?
c) Check if large hierarchies are used and the entry hierarchy level is as deep as possible. This limits the levels of the hierarchy that must be processed.
C)Strategy - High Frontend Runtime
1) Check if frontend PC are within the recommendation (RAM, CPU Mhz)
2) Check if the bandwidth for WAN connection is sufficient.
Hope this helps you..

Performance issue in Report.

Hello DBAs,
We have a report which usually takes around 2 hours to complete in our instances "A" and "B".
We created an index (CREATE INDEX xxexh_order_lines_n2 ON oe_order_lines_all (TRUNC(last_update_date));
) in instance A and the report now takes only 10 minutes to complete.
We created the same index in instance B but the problem is still the same.
Please provide your feedback as to what do I need to check/compare between the 2 instances to find out the the failure of the index in the latter one.
Thanks in advance,
Vijay

Pl post details of OS, database and EBS versions.
Is one instance cloned from the other ? Pl trace the concurrent program on both instances and post the tkprof output that includes the explain plan.

Report performance Issue in BI Answers

Hi All,
We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
Could any once suggest to improve the performance in BI answers?
Thanks in advance,

I hope you dont have many case statements and complex calculations that you do in the Answers.
Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
hope it helps
thanks
