Performance issue in ODI Tool

Hi ,
I have source table which is having 12 million records and am using ODI Interface which directly pulls the data to the target table which is created in another database.
I am using IKM SQL Control append KM While pulling data to target .
In Source to staging it is --> LKM SQL to Orqacle .
This interface is an one to one mapping there is no other transformation.
This task took around 3hr55minurtes to complete.
Is there any way to imporve the perforamnce of this interface.or this is tghe only way to do ??
It took more time in populating the c$_tableName,i$_tablename and E$_tablename rather then populating the target table.
There is no index created in target table.
Thanks
Prasanna

HI
Thanks for the reply.
My source db is oracle .
I tried other way instead of using ODI Interface i used odi procedure which just pull the data using select query and insert the data in target table. and it will commit the every 1000 records .
Performance imporved,it completed in 1hr 5 minutes using interface it is 2hr 50min.
But still i want to use the odi interface . Can u please suggest suitable knowledge module for this approach.
Thanks

Tool for diagnosing performance issues in oracle database

Is there any tool to diagnose performance issues in queries and stored procedures in oracle similar to sql profiler for sql server
Thanks

you can use oem oracle enterprise manager to diagnose and monitor database .
Chapter 10: Monitoring and Tuning the Database(refer the link , oracle obe series, step by step procedures with screenshot presentation)
This chapter introduces you to some of the monitoring and tuning operations as performed through Enterprise Manager.

Annotation process tools build performance issue

Annotation process tools is taking 85 minutes to compile page flow files. Is there any suggestion to improve performance.

As you probably already have gathered, you have different execution plans in the two environments. There could be different reason why this happens, for instance different profiles of the data. But more likely it is due to that in the slow environment, the
plan was built from some atypical set of input parameters, which causes a performance issue when the procedure is run in a normal fashion.
When you say that the query has a lot of isnull and convert functions I get a little worried. If it is only in the SELECT list, it's not evil, but if functions are used in the WHERE or ON clauses, the query might benefit from a review, and possibly also
the data model. But this is pure speculation at this point.
I would suggest more than one course of action. As a short-term solution, you run UPDATE STATISTICS WITH FULLSCAN on all tables involved, as out-dated statistics can also be explanation for why you got a bad plan. New statistics should trigger a recompilation.
But even if this resolves the issue, it may not be feasible in the long run, because the events indicate that the query is sensitive to something and the bad plan could come back any day. For this reason, it might be a good idea to make sure that the query
does include inappropriate constructs, and you also need to review that there are good indexes in place.

Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
Hello,
I just want to reiterate that we are very committed to working on
this issue, and that our goal is to find out the root of the problem. But
first I'd like to narrow down the avenues by process of elimination.
Open Cursor is something that is commonly used in today's RDBMS. I
know that you must test your query in ISQL using some kind of execute
immediate, but Sybase should be able to handle an open cursor. I was
wondering if your Sybase expert commented on the fact that the server is
not responding to commonly used command like 'open cursor'. According to
our developer, we are merely following the API from Sybase, and open cursor
is not something that particularly slows down a query for several minutes
(except maybe the very first time). The logs show that Forte is waiting for
a status from the DB server. Actually, using prepared statements and open
cursor ends up being more efficient in the long run.
Some questions:
1) Have you tried to do a prepared statement with open cursor in your ISQL
session? If so, did it have the same slowness?
2) How big is the table you are querying? How many rows are there? How many
are returned?
3) When there is a hang in Forte, is there disk-spinning or CPU usage in
the database server side? On the Forte side? Absolutely no activity at all?
We actually have a Sybase set-up here, and if you wish, we could test out
your database and Forte PEX here. Since your queries seems to be running
off of only one table, this might be the best option, as we could look at
everything here, in house. To do this:
a) BCP out the data into a flat file. (character format to make it portable)
b) we need a script to create the table and indexes.
c) the Forte PEX file of the app to test this out.
d) the SQL staement that you issue in ISQL for comparison.
If the situation warrants, we can give a concrete example of
possible errors/bugs to a developer. Dial-in is still an option, but to be
able to look at the TOOL code, database setup, etc. without the limitations
of dial-up may be faster and more efficient. Please let me know if you can
provide this, as well as the answers to the above questions, or if you have
any questions.
Regards,

We did that trick already.
When it is hanging, I can see what is doing.
It is doing OPEN CURSOR. But not clear the exact statement of the cursor
it is trying to open.
When we run the query directly to Sybase, not using Forte, it is clearly
not opening any cursor.
And running it directly to Sybase many times, the response is always
consistently fast.
It is just when the query runs from Forte to Sybase, it opens a cursor.
But again, in the Forte code, Alex is not using any cursor.
In trying to capture the query,we even tried to audit any statementcoming
to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

Performance Issues with Photoshop CS6 64-Bit

Hello -
Issue at hand: over the course of the last few weeks, I have noticed significant issues with performance since the last update to PS CS6 via the Adobe Application Manager, ranging from unexpected shut downs to bringing my workstation to a crawl (literally, my cursor seems to crawl across my displays). I'm curious as to if anyone else is experiencing these issues, or if there is a solution I have not yet tried. Here is a list of actions that result in these performance issues - there are likely more that I have either not experienced due to my frustration, or have not documented as occuring multiple times:
Opening files - results in hanging process, takes 3-10 seconds to resolve
Pasting from clipboard - results in hanging process, takes 3-10 seconds to resolve
Saving files - takes 3-10 seconds to open the dialog, another 3-10 seconds to return to normal window (saving a compressed PNG)
Eyedropper tool - will either crash Photoshop to desktop, or take 5-15 seconds to load
Attempting to navigate any menu - will either crash Photoshop to desktop, or take 5-15 seconds to load
Attempts I've taken to resolve this matter, which have failed:
Uninstalled all fonts that I have added since the last update (this was a pain in the ***, thank you Windows explorer for being glitchy)
Uninstall application and reinstall application
Use 32-bit edition
Changing process priority to Above Normal
Confirm process affinity to all available CPU cores
Change configuration of Photoshop performance options

Performance Issue in Dashboard using SAP BW NetWeaver Connection

HI Experts ,
We developed Dashboard which is based on BW Queries, However it is taking considerable amount time while executing.
We are using BO Dashboard SP2 version ,BO 4.1 and BI system 7.01 .
We are looking for few clarifications on SAP BO Xcelsius Dashboards.
Though we know limitations on component number and data volumes which could badly affect performance of the dashboard, We do have a requirement to handle huge data volumes and multiple components. Our source data lies in SAP BI system and we are using BICS connectivity/ Webi with QAAWS for updating data in BO dashboard .
Our requirement is too complex where we should be in a position to meet user expectations for complete view 75 KPI’s in a single Dashboard.
We have scenarios like YTD ,QTD and MTD other complex calculations in Bex Query.
Here are my questions,
Is there any way to provide complete functionality using large data sets to the users with the current architecture without any performance issues?
Are there any third party tools which can be used with BO Dashboard for the performance improvement and handling huge volumes?
Do you suggest any alternate solution for complete functionality?
Many thanks for your inputs in advance!
Regards
Venkat

Hi Rajesh,
Thank you so much for your response.
I have tried the way you suggested. But here my issue is , I have a prompt in my webi report based on months selection and it is a single valued prompt.
so I was able to schedule my report only for one month;whereas my dashboard needs to show values for one year data based on the months the user will select in the dashboard.
Though i use the WebI instance data in the dashboard , i getting only one month value, also I am not able to associate the selected month for the WebI instance in dashboard.
Is there any option to schedule webI report for different months and the dashboard has to pick the 12 months instance and the combo box selection in the dashboard must associate with it??
Please help me with your thoughts.

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.

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...

Performance issue with pl/sql code

Hi Oracle Gurus,
I am in need of your recommendations for a performance issue that I am facing in production envrionment. There is a pl/sql procedure which executes with different elapsed time at different executions. Elapsed Times are 30minutes , 40 minutes, 65 minutes , 3 minutes ,3 seconds.
Expected elapsed time is maximum of 3 minutes. ( But some times it took 3 seconds too...! )
Output on all different executions are same that is deletion and insertion of 12K records into a table.
Here is the auto trace details of two different scenarios.
Slow execution - 33.65 minutes
Stat Name Statement Per Execution % Snap

Invalidations 0 N/A N/A
Version Count 4 N/A N/A
Sharable Mem(KB) 85 N/A N/A
 -------------------------------------------------------------For security reasons, I cannot share the actual code. Its a report generating code that deletes and load the data into table using insert into select statement.
Delete from table ;
cursor X to get the master data ( 98 records )
For each X loop
insert into tableA select * from tables where a= X.a and b= X.b and c=X.c ..... ;
-- 12 K records inserted on average
insert into tableB select * from tables where a= X.a and b= X.b and c=X.c ..... ;
-- 12 K records inserted on average
end loop ;1. The select query is complex with bind variables ( explain plan varies for each values )
2. I have checked the tablespace of the tables involved, it is 82% used. DBA confirmed that it is not the reason.
3. Disk reads are high during long execution.
4. At long running times, I can see a db sequential read wait event on a index object. This index is on the table where data is inserted.
All I need to find is why this code is taking 3 seconds and 60 minutes on the same day and on the consecutive executions ?
Is there any other approach to find the root cause of this behaviour and to fix it ? Kindly adivse.
Thanks in advance your help.
Regards,
Hari

There is a pl/sql procedure which executes with different elapsed time at different executions. Please reedit your post and add some code tags around the trace information. This would improve readability greatly and will help us to help you
example
{code}
select * from dual;{code}
Based upon your description I can imagine two things.
a) The execution plan for the select query does change frequently.
A typical reason can be not up to date statistics.
b) Some locking / wait conflict. For example upon a UK index.
Are there any other operations going on while it is slow? If anybody inserts a value, then your session will wait, if the same (PK/UK) value also is to be inserted.
Those wait events can be recognized using standard tools like oracle sql developer or enterprise manager while the query is slow.
Also go through the links that are in the FAQ. They tell you how to get better information for makeing a tuning request.

BW Performance issue

Hi,
We have done reorge for four tablespaces PSAPBTABI, PSAPBTABD, PSAPODSD, PSAPODSI in our BW System 7.0. And we have created new tablespaces for above our tablespaces like PSAPODSINEW for all the above tablespaces and made the old tablespaces as offline. After doing this activity we are facing lot of performance problems.
For e.g while our BW guys are running one report for the portal it is executing but after a long time like after 2+ hours the page goes empty. The report is CL_SQL_RESULT_SET=============CP, not only this report but lot of reports. We have done statistics update for the tables that report uses using BRCONNECT and also rebuild the indexex for all the tables. But still no luck.

Hi,
For the BASIS related performance issues :
1. This is mostly DBA related : Keeping an eye on the DB space to monitor the growth of the database and look at space available and needed to prevent shutting down the BW server.
2. Making sure that backups don't consume a lot of time to interfere with daily operations.
3. Doing load balancing
4. Making sure IDocs are flowing freely.
5. Making sure that shared drives and servers don't overshoot the capacity.
6. Patching servers and server instances to improve performance.
The BW consultants can monitor the the space , etc using tcode DB02. The DBAs have their own tools to monitor these parameters.
Cheers,
Kedar

Performance issues since upgrade

I am on a late 2011 MacBook Pro and am having severs performance issues since upgrading to Mavericks. I fear my issues may be related to company installed anti-virus (which I cannot remove), but I was hoping someone could look over my EtreCheck for other potential solutions.
One really odd issue I am having, which I cannot seem to find good information for on Google, is at least 4-5 times a day my Mac just stops. No beach ball, no anything, for about 1-5 minutes. Then it's fine. Maybe just me grasping at straws, but it seems related to a when webpage loads a bunch of images? I always use Safari btw, but testing other browsers, like Chrome & Firefox, it happens as well.
I have also removed TotalFinder and have noticed no improvement and still have the above issue.
Thanks in advance!
Here is my EtreCheck:

There we have it, I think that that is all you need to know to perhaps give opinions and advice. Allow me to elaborate on why I am posting today after browsing this wonderful forum for the last two weeks. (...and by the way, my hat's off to some of you knowledgeable regulars for helping out a lot of newbies and folks in trouble!) Without further adieu:
Problem #1: POWER ISSUE
When, or if, I remove AC Power from my PC for whatever reason I run into a problem in which after reconnecting the AC Power and attempting to turn on the computer it goes into a 3-5 second startup loop in which the PC does not post, but rather cycles power to all of the components indefinitely. I notice the LEDs on my optical drives cycling repeatedly ad infinitum until I power off using the 4-second hold method, and then press the power button again. At this point the PC boots up fine, and boots up fine going forward from all restarts and shut downs. How strange? I've never, EVER, encountered something like this before.
Problem #2: PERFORMANCE ISSUE
This PC has a handful of serious performace issues.
3dMark03 scored horribly.
Prime95 runs ridiculously slow although there are no erros! It runs much more quickly on my work PC which is a PIII 866mhz with 384MB of PC133 RAM.
I receive, on no regular frequency, or while doing anything in particular, Explorer memory errors. Not BSOD's mind you, but "...blah blah blah referenced memory address xxxxx-xxxxx and could not be written". This causes Explorer to restart itself, blowing away the start menu, task bar, and any Explorer windows open. They reappear, of course, without incident.
The most off performance issue of all is that when opening an Explorer window for either of my IDE HDs, designated D and E drives, I find that when using the highlighting rectangle tool the Explorer window freezes or lags. I can double-click and open or move/copy files without incident, but if I attempt to highlight by this method this halt or lag occurs.
Also, since my update of the BIOS from 1.2 to 1.7, and then to 1.8 system startup times prior to Windows loading are HORRID. I have disabled just about everything, and yet the SATA BIOS loads for 5 seconds, and then I must wait 20 seconds for Windows itself to come to the login screen. No other BIOS related issues to report per se, but this is terrible for what should be a blazingly fast computer.
Now let's see.. what have I tried to do to repair the issues?
1) 2 BIOS flashes. First from 1.2->1.7, and then from 1.7->1.8. Ostensibly this was just "because". The power user need to have the latest! I noticed the incorrect CPU temperature being reported, however.. This led to me buying this massive ThermalTake HSF to replace my stocker. I also added more thermal goop than I ever have before, as well as a PCI slot fan before I became aware that it was a BIOS issue! GRRRR MSI.
2) I thought perhaps for the one issue that one of the hard drives was an issue, and even perhaps for power, but I replaced each with new drives and tested all 4 on another PC. NO problems. Also I should perhaps mention that my IDE drives are all hooked up using Antec Cobra cables. Expensive yes, but why the hell not, right? I've never seen a hang-off grounding wire for IDE before. Decided not to use them as I could think of a great place to screw them in, nor have other PC using them had trouble skipping the ground wire.
3) I unplugged every molex cable, the 4-pin CPU power, and the 20-pin ATX power and rerranged them all - as well as removed and then reinserted the RAM.
4) I tried changing my memory timings and power management settings, etc in BIOS. Nothing seem to impact the issue. I didn't fiddle with the voltages, but I should not need to running the RAM at SPD or lower settings and without overclocking the system at all!
5) Another issue that I had that seems to have vanished, come back, vanished, and then come back a "little bit" is my USB ports. When set to enable legacy devices in BIOS my USB items like my Logitech wireless keyboard would just cycle power and refuse to function. Also my UPS connected VIA USB seems to sometimes handshake with Windows and sometimes not. I've tried using all of the different ports, etc but the problem remains. I NEED 6 ports for my devices so it is all that I could do!
6) I have an Enermax 550w EG651P-VE(FMA) with 36 amps on each voltage rail on it's way, and it should arrive tomorrow. Despite all of the crap regarding power supplies that I see on this board I am not confident that it's the problem. That Antec PSU should be able to hold it's on with 20 amps on the +12v channel. C'mon now. I build a nearly identical system with the same power supply for a customer and he has no problems at all. He also has 3 HDs, same motherboard, etc.. the only difference is he has but one optical drive and a 2800+ rather than a 3200+. That power difference should be decimal nature in amps needed.
...oh and the sound card is in PCI slot 3, for those that remember the glory days of sound card IRQ issues that Creative was once notorious for... oh, and I disable the ethernet boot device, etc so my slow startups should not be related. My serial ATA drive is also on connection 1 of the VIA controller.. Promise can kiss my a**.
Soooo.. Show me what a n00b I am, oh great ones. I've built over 100 PCs since 1998 for myself, friends, families, and customers... and I've never seen an issue like this one! I'm no dummy, but please don't assume too much. Other pros on here know full well you can forget the most simple mundane detail in spite of experience! I want to solve this problem. I am on the verge of shelling out for a new motherboard and processor of the 939 pin variety.. and am now wary of MSI's long awaited socket 939 K8 Neo2 board despite it's awesome reviews. MSI has never really given me trouble before.. but I don't really want to spend money to the order of $200+ for that damned Gigabyte board. Gigabyte has always been good to me as well. Save my wallet! PLEASE!!!
Thanks so much everyone, I tried very hard not to leave out any details!

The startup problem might just be a screwy psu. Your antec *should* be able to power your stuff just fine, but maybe it is defective in some strange way.
What is your 3dmark03 score? If it is 3000-4000, (approx perf. level of ati 9600xt), then it is fine.
Check your memory using memtest86+, and try underclocking it to ddr333.
UNplug usb devices, and see if it speeds up boot. Also, I would not recommend bios 1.8 since people seem to have some troubles with it.
Also, try disabling agp fast writes, disabling spread spectrum, and maybe boosting ram voltage a tiny bit.
Try booting without your audigy plugged in, and try booting barebones (nothing but 1 hard drive with os) and see what happens.
I'm no expert, but you might get lucky trying these steps.

Performance issues related to logging (ForceSingleTraceFile option)

Dear SDN members,
I have a question about logging.
I like to place my logs/traces for every application in different log files. By doing this you have to set the ForceSingleTraceFile option to NO (in the config tool).
But in a presentation of SAP, named SAP Web Application Server 6.40; SAP Logging and Tracing API, is stated:
- All traces by default go to the default trace file.
- Good for performance
- On production systems, this is a must!!!
- Hard to find your trace messages
- Solution: Configure development systems to pipe traces and logs for applications to their own specific trace file
But I want the logs/traces also by our customers (production systems) in separate files. So my question is:
What are the performance issues we face, if we turn the ForceSingleTraceFile option to NO by our customers?
and
If we turn the ForceSingleTraceFile to NO will the logs/traces of the SAP applications also go to different files? If so, then I can imagine that it will be difficult to find the logs of the different SAP applications.
I hope that someone can clarify the working of the ForceSingleTraceFile setting.
Kind regards,
Marinus Geuze

Dear Marinus,
The performance issues with extensive logging are related to high memory usage (for concatenation/generation of the messages which are written to the log files) and as result increased garbare collection frequency, as well as high disk I/O and CPU overhead for the actual logging.
Writing to same trace file, if logging is extensive can become a bottleneck.
Anyway it is not related to if you should write the logs to the default trace of a standard location. I believe that the recommendation in the documentation is just about using the standard logging APIs of the SAP Java Server, because they are well optimized.
Best regards,
Sylvia

Performance issues -- related to printing

Hi All,
I am haviing production system performance issues related to printing. endusers are telling the printing is slow for almost printers. We are having more that 40 to 50 printers in landscape.
As per my primary investigation I didnt find any issues in TSP01 & TSP02 tables. But I can see the table TST01 and TST03 table having many number of entries (more that lakh). I dont have idead about this table. Is ther eany thing related to this table where the print causes slowness or any other factors also makes this printing issue .. Please advice ..
thanks in advance

Hai,
Check the below link...

TemSe cannot administer objects that require more than two gigabytes of storage space, regardless of whether the objects are stored in the database or in the file system. Spool requests of a size greater than two gigabytes must therefore be split into several smaller requests.
It is enough if you perform the regular background jobs and Temse consistency checks for the tables.
This will help in controlling the capacity problems.
If you change the profile parameter rspo/store_location parameter value to 'G' this will make the performance better. The disadvantages are TemSe data must be backed up and restored separately from the database using operating system tools, In the event of problems, it can be difficult to restore consistency between the data held in files and the TemSeu2019s object management in the database. Also you have take care of the Hard disk requirements because in some cases, spool data may occupy several hundred megabytes of disk storage. If you use the G option, you must ensure that enough free disk space is available for spool data.

SQL Performance issue: Using user defined function with group by

Hi Everyone,
im new here and I really could need some help on a weird performance issue. I hope this is the right topic for SQL performance issues.
Well ok, i create a function for converting a date from timezone GMT to a specified timzeone.
CREATE OR REPLACE FUNCTION I3S_REP_1.fnc_user_rep_date_to_local (date_in IN date, tz_name_in IN VARCHAR2) RETURN date
IS
tz_name VARCHAR2(100);
date_out date;
BEGIN
SELECT
to_date(to_char(cast(from_tz(cast( date_in AS TIMESTAMP),'GMT')AT
TIME ZONE (tz_name_in) AS DATE),'dd-mm-yyyy hh24:mi:ss'),'dd-mm-yyyy hh24:mi:ss')
INTO date_out
FROM dual;
RETURN date_out;
END fnc_user_rep_date_to_local;The following statement is just an example, the real statement is much more complex. So I select some date values from a table and aggregate a little.
select
stp_end_stamp,
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
stp_end_stampThis statement selects ~70000 rows and needs ~ 70ms
If i use the function it selects the same number of rows ;-) and takes ~ 4 sec ...
select
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin'),
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin')I understand that the DB has to execute the function for each row.
But if I execute the following statement, it takes only ~90ms ...
select
fnc_user_rep_date_to_gmt(stp_end_stamp,'Europe/Berlin','ny21654'),
noi
from
select
stp_end_stamp,
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
stp_end_stamp
)The execution plan for all three statements is EXACTLY the same!!!
Usually i would say, that I use the third statement and the world is in order. BUT I'm working on a BI project with a tool called Business Objects and it generates SQL, so my hands are bound and I can't make this tool to generate the SQL as a subselect.
My questions are:
Why is the second statement sooo much slower than the third?
and
Howcan I force the optimizer to do whatever he is doing to make the third statement so fast?
I would really appreciate some help on this really weird issue.
Thanks in advance,
Andi

Hi,
The execution plan for all three statements is EXACTLY the same!!!Not exactly. Plans are the same - true. They uses slightly different approach to call function. See:
drop table t cascade constraints purge;
create table t as select mod(rownum,10) id, cast('x' as char(500)) pad from dual connect by level <= 10000;
exec dbms_stats.gather_table_stats(user, 't');
create or replace function test_fnc(p_int number) return number is
begin
 return trunc(p_int);
end;
explain plan for select id from t group by id;
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from t group by test_fnc(id);
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from (select id from t group by id);
select * from table(dbms_xplan.display(null,null,'advanced'));Output:

Dashboard Performance Issue

HI Ingo,
Thanks a lot for the wonderful postings in SDN and for your blogs on SAP BI/BO Solution architecture.
I am looking for few clarifications on SAP BO Xcelsius Dashboards.
Though I know limitations on component number and data volumes which could badly affect performance of the dashboard, We do have a requirement to handle huge data volumes and multiple components. For drilling down and complete analysis for the users. Our source data lies in SAP BI system and we are using BICS connectivity/ Webi with Live office for updating data in Xcelsius.
Our requirement is too complex where we should be in a position to meet user expectations for complete multidimensional analysis by different criterion.
We have scenarios like, Delivery performance where we need to get Case fill rate, Line fill rate, OTIF (On Time In Full), etc .along with that alerts and based on that we should be providing short term, long term and medium term analysis. (also we have scenarios from Sales, Inventory , Supply chain which are interlinked to each other).
Here are my questions,
1.     Is there any way to provide complete functionality using large data sets to the users with the current architecture without any performance issues?
2.     Are there any third party tools which can be used with Xcelsius for the performance improvement and handling huge volumes?
3.     Do you suggest any alternate solution for complete functionality?
Awaiting your response.
Thanks & Regards,
Paramesh Kumar Bada

hi,
Generally, it would be better to display summarized information in Xcelsius.
So at database/Source level, maintain aggregated information which will serve as input to Xcelsius.
You can use Crystal Reports and Xcelsius together.
Because Crystal reports has the capability of embedding Xcelsius components within the report.
So Charts can be built using Xcelsius and embed in Crystal. whereas Table related content can be developed within Crystal report directly. Also, try to provide URLs(Open Document concept) from Xcelsius to Crystal reports to drill-down from Summary data to detailed data.

Vamsee
