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

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,
MarilynFrom 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. -
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.
ThanksIs 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);

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
ChetanHi 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.
***MODIFY ZTABLE.*****
ENDLOOP.

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 XIHi 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 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.
Regards
MuraliWe 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 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,
AbdullahI 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

How to increase performance in webi report?
Hi Experts,
I have create report top of universe with 1 query.But inside report i created multiple tabs.Data also less but while executing the report it will take so much time. How should decrease the waiting time.
I followed performance optimization:
1. ALL formula created in Bex itself.
2.Enable Query Stripping
3. Remove auto width and auto height.
4.scheduling the report.
Please tell another some performance tuning.You'll want to determine where the time is being spent. You can trace the BW side to see how long it is taking on that end but it is probably the design of the report that is taking the time. Are you using a UNV universe going to a BEx query or a BICs based connection?
Query Stripping is automatically on for BI 4.0 SP5+ for BICs connectivity. There are also a number of optimizations that can help improve performance in the newer Support Packages.
Determining where the bottleneck is is the first step.
thanks

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 issues in reporting side
hi gurus,
how to improve performance in reporting side.
thankuHi 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..

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

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,

How should I report forum performance issues?
The forums rely heavily on the caching features of browsers to improve the speed of page rendering. Performance of these forums should greatly improve after a few pages because more and more of the images, css and javascript is cached in the browser. As a consequence, when reporting forums performance issues the report should include some information on the state of the browser cache to determine whether the issue is a browser issue or a server issue. Such detailed information is generally not available from just watching the browser screen, but needs to come from specialized tools such as performance monitor plugins and recording proxies.
The preferred report method for performance issues is to use the speed reporting features build into or available as a plugin for a browser for both the page you want to report a problem with and several refence pages in the site. Detailed instructions are listed below separated out for different browsers. If possible, please use Firefox for submitting the report because it provides an export format that can be read back electronically.
Known performance issues
The performance issues with any screen with a Rich Text Editor, such as the Reply window and the compose Private Message window have been acknowleged and improvements are being implemented.
Mozilla Firefox (preferred)
Warning: it is currently not recommended to generate a speed report when logged in. The speed report has enough detail for somebody else to hijack your session and impersonate you on the forums. If you really must report while logged in, make sure you log out your browser after generating the speed report and wait at least 4 hours before posting.

When you report a performance problem please attach the 6 exports from the Firebug Net panel and an explanation of how you are experiencing the issues (for instance how much slower it is then normal) and include a description of your internet connection (dial-up, dsl, cable etc.) and the country from where you are connecting. If you have non-standard tweaks to your Firefox configuration (such as pipelining enabled) or are running any plugins please include that information in your report as well.

Since Google Chrome does not have an export format for the Resource Tracking information best current practice is to take a screenshot and note the hover details for any resource with a tail that is longer then 25% of the total load time. When you report a performance problem please attach the screenshots and an explanation of how you are experiencing the issues (for instance how much slower it is then normal) and include a description of your internet connection (dial-up, dsl, cable etc.) and the country from where you are connecting.
Apple Safari
The Apple Safari Web Inspector has a Resources panel similar to the Resources panel in the Google Chrome developer tools.To get there, follow these steps:
Show the menu bar.
Go to preferences
Go to the Advanced Tab
Check “Show Develop menu in menu bar”.
From the Develop menu select “Show Web Inspector”.
Collecting the performance information and exporting works exactly the same as in Google Chrome. Please refer to the instructions for Google Chrome.
Microsoft Internet Explorer
IE does not have native features to analyze web traffic. No plugins have been found that produce the required information (please let us know if we missed any). For now, please reproduce the issue with Firefox, Chrome or Safari.
Please note that due to the reliance on Javascript for the interactive effects the performance of these forums will be much better on MS IE 8 then on previous versions of MS IE.Hi
It works, check once again...
