Performance problems on Webi

I have serious problems whit the performance Webi reports of universes from the querys SAP-BW. When I run the same query in BW the delay is more a 10 seconds, but this same query in WeBi the time is more a 15 minutes.
I have install BOE 3.0 after upgrade to 3.1 I applied the Fix Pack 1.2 for Windows. I have installed the kit of integration with SAP, and in the development upgrade the kit.
In BW the level is SAPKW70020.
Any idea.

Hello Diego,
you mentioned that you compared a BEx Query with the Web INtelligence report. Could you provide more details here ?
- what are the elements in the rows, columns and free characterisitcs in the BEx Query ?
- was the query execute as designed in the BEx Query Designer with BEx Web Reporting ?
- what are the elements in the WebIntelligence Query panel ?
thanks

Performance Problems with Web Layouts in web interface

Hello Gurus,
We have a a BPS web interface tool which has the following design:
1> A web interface with several tabs
2> Each tab has around 3-4 input layouts which are dependent on each other
3> In all there are 120-140 layouts that the tool uses...
My questions were in term of performance
1> Is there a limit to how many web layouts you can use per page/tab/view or if SAP recommends specific number of web layouts per page/tab/view ?
2> If there is a limitation...our intention was to convert all the display layouts into BW reports so as to increase the performance of the tool....
3> Would like to know the restriction on the number of users who can log into the tool as a specific point of time ? We may have 50-60 minimum using this tool.
I would appreciate your help in this regard.
Thanks in advance

Hello Rashmi,
Have you got a chance to look at the performance guide and SAP notes on BPS performance. If not here are the details

Performance problem of webi

When I run a single webi report, the repsonse is normal, i.e., around 10s. However, when there are 5 users concurrent executing the same report, with same input criteria, the performance degrades significantly, i.e., around 30s - 40s to retrieve the reprot for each of the user.
Anyone knows where the bottlenecks are likely in and which areas should be looked at for tune-up?
Thanks

If you have any monitoring set up on the server - you can check for cpu or memory utilisation.
There are some simple actions that could be taken. You could set up Web Intelligence Report server properties through CMC to enable options to share report data etc. However be careful if your users have been promised the latest data for each refresh.

Forms performance problem on the web, using webutil.

When starting the webutil-demoform on the Application Server,
webutils eight javabeans is loaded in 1 second.
I'm using &WebUtilLogging=Console&WebUtilLoggingDetail=Detailed for logging this.
When starting the same form from client the beans is loaded in ~30-40seconds.
Any suggestions to figure out why?

Problem solved!
Don't use the IP-address in the URL, use hostname or add an entry in your hostfile on the client. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5092063

Bad performance of Java Web Report in BI 7

We are experiencing poor performance with Java web application(EP)
comparing to that with ABAP web.
We migrated our BI reports from the ABAP web interface to the Java web
interface due to our upgrade to Netweaver2004 environment.
The problem is that it takes much longer time to load the BI reports in
Java web than in ABAP web.
It is the same situation in RSRT. Java web needs more time to execute
the same query.
there is no EP logon performance delay, so I think the EP is configured good.
But the response time of BI Java Web Report is delayed average of 4~5
seconds in every Query compared in that of ABAP Web report.
Anyone experience this situation?

Hi,
I am facing similar problem. How did you solve it?

JRC 2: Performance Problem

Hi.
Our reporting component used JRC 1.x before we upgraded to JRC 2.x. We got two issues after upgrading.
First issue I solved already with a workaround which I published on stackoverflow.com. (1) Does anyone knows where I will find the issue management system to report this issue?
Second issue occurs big performance problem within our project. We opened a report with 6 subreports (which includes 1 upto 3 tables) in 2-4 seconds using JRC 1. If we will open same report using JRC 2, we wait upto 60 seconds.
This methods requires more time with JRC 2 comparing to JRC 1:
ReportClientDocument#open(String, int);
SubreportController#setTableLocation(String, ITable, ITable)
DatabaseController#setTableLocation(ITable, ITable)
Each invocation of one of these methods requires 2-4 seconds.
Thank you in advance.
Best regards
Thomas

Performance problems with Leopard 10.5.1

Hello,
I use an iMac 24 Alu 2,8Ghz and upgraded to Leopard. There are some major performance problems and bugs in the recent version of Leopard:
1. While accessing USB devices, the display speed, windows moving, animations etc. slow down
2. Adobe CS3 Photoshop 10.01 and Flash CS3 are sometimes extremly slow. I tried the recent demo packages from Adobe:
2.1. The Photoshop dialogue "save for web" slows down the system completly, and this problem stays when quitting Photoshop. A restart is neccessary then.
2.2. Flash CS3 movie preview is very slow and stuttering. It's so slow you cannot imagine how the real movie flow will be.
2.3. Recent Flash Player 9,0,115,0 with hardware acceleration enabled doesn't really work with QuartzGL enabled Leopard: The movies slow down a lot. Try www.neave.tv for example.
3. Safari, Mail and other bundled software hang sometimes. You have to force quit them then. It doesn't matter whether QuartzGL is enabled or not. This especially happens to my system if it is online for some hours.
4. A lot of Apple applications doesn't seem to work with 2dextreme enabled. Why this? Apple supporters told me in Leopard there will be a much better 2dextreme support. Also Quartz2dExtreme in OSX 10.4 worked with all applications and i guess it's the same feature like "QuartzGL" in Leopard. So Leopard isn't finished here. It would be nice if Apple could make it's own software QuartzGL compatible.
5. Very often the desktop slows down or lags. This is the main reason I often still witch to Windows XP PC to do work in a faster, less annoying way.
6. Safari crashes randomly sometimes. It is unstable still. Also it crashes more often if you resize/move the window a lot, so I guess it is a graphics extension-related problem.
I hope you people from Apple will fix these annoying points and optimize your new system in the next update release.
Best regards

Thanks for you answer. I repaired in the way as described above. There were some errors, some file index was wrong (don't remember exactly the phrase), now the DU reports the partition was successfully repaired / the volume appears to be ok.
The crashes in Safari are gone, but all other described problems still exist. Adobe CS3 is not really usable for me.
By the way, in iMacSoftwareUpdate 1.3, which was replaced by OSX 10.5.1 update, there is one extension called AppleVADriver.kext that does not exist in the OSX 10.5.1 update. Is it an important extension?

Performance Problems on Faces Navigation Diagram and Hyperthreading query

Am I the only one having performance problems when dealing with Faces-Config Diagrams of about 35 JSPs displayed on the sheet. using Jdev 10.1.3 It's taking my workstation about a full minute and a half to update the name of an arrow. The most stressed component during this task seems to be the CPU.
And just another question has anybody investigated how is the performance of Jdev affected by either enabling or disabling hyperthreading? In my case my CPU usage manages to reach only 50%. I'm tempted to switch HT off to let JDev use all the cpu power. if that would be the case.

Hello Diego,
you mentioned that you compared a BEx Query with the Web INtelligence report. Could you provide more details here ?
- what are the elements in the rows, columns and free characterisitcs in the BEx Query ?
- was the query execute as designed in the BEx Query Designer with BEx Web Reporting ?
- what are the elements in the WebIntelligence Query panel ?

Performance problem with Mavericks.

Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

If you are still experiencing slow down issues, it maybe because of a few other reasons.
Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
Your Mac's hard drive maybe getting full.
Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Your Mac may have way too many applications launching at startup/login.
Your Mac may have old, non-updated or incompatible software installed.
Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
Your Mac could have connected third party hardware that needs updated device drivers.
It would help us to help you if we could have some more technical info about your iMac.
If you so choose, please download, install and run Etrecheck.
Etrecheck was developed as a simple Mac diagnostic report tool by a regular Apple Support forum user and technical support contributor named Etresoft. Etrecheck is a small, unobstrusive app that compiles a static snapshot of your entire Mac hardware system and installed software.
This is a free app that has been honestly created to provided help in diagnosing issues with Macs running the new OS X 10.9 Mavericks.
It is not malware and can be safely downloaded and installed onto your Mac.
http://www.etresoft.com/etrecheck
Copy/paste and post its report here in another reply thread so that we have a complete profile of your Mac's hardware and installed software so we can all help continue with your Mac performance issues.
Thank you.

Serious performance problems on iWeb site

Can anyone help me find the problem with peterlance.com? It looks like author Peter Lance uses iWeb to update his web site. He redesigned it recently (and did not use iWeb for the old design). Anyway, it has serious performance problems on Internet Explorer, which I was hoping you guys could help pinpoint? Is there something simple I can tell him to try to fix the problem? He is launching a new book on Tuesday so he will be getting a lot of traffic, but for now the response time is not very good. Any suggestions?
In particular, each new page seems to hang for about ten seconds and freeze using Internet Explorer 6. Any fixes?
I mean, fixes other than: "Don't use Internet Explorer!"
http://www.peterlance.com/Peter%20Lance/Home/Home.html
name="Generator" content="iWeb 1.1.2"

Welcome to the discussions, TopDog08.
There are several plain .jpg's and that's good, but you need to convert every .png on the page (or as many .png's as you can) to a .jpg. For example,
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage46.png
Convert that to a jpg, then replace the graphic and text on the iWeb page with this converted jpg (some have has success using Downsize http://www.stuntsoftware.com/Downsize/)
The ones you won't be able to do anything about are the ones that are a part of the blog, but that will be only 5 images instead of the many you have now.
This image
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage50.png
Is covering part of your menu which is why it appears that only the top half is sensitive to rolling over. You'll have to adjust your layout to account for this.
Another area to look at, there are white boxed png's surrounding the amazon book covers at the top.
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/imageEffectsAboveAli%20Mug%20TPI%20jpg.png
Another set of .png's you'll have to get rid of. How did those get put on the page?
What you see happening with IE is a java script running to fix IE's problem with png's. The fewer .png's you have, the less of a problem with IE you have.

Problem with web.show_document with Jinitiator and Firefox

Not sure Firefox 2.0 is officially certified with Forms 9.0.4.1 and Jinitiatorbut regardless we have some users who want to use this combination. Everything seems to work fine except for the calls to web.show_document which opens a new browser window and displays some html etc.
The problem is that even though the client Forms JVM is Jinitiator (1.3.1.18 or .21) when the call to web.show_document occurs somehow the Sun Java Plugin starts and having the two JVM's at once causes a fatal crash in Firefox. Can anyone suggest a way to preven the second JVM from opening?
When the user uses the Sun Plug as the client Forms JVM there is no problem as the second JVM does not open. Unfortunately some users insist on Jinitiator with Firefox hence the problem. -quinn

James,
This whole applet embedded in a browser model for webforms is driving us batty at times. The list of problems includes:
1) Users are constantly tempted by browser controls and accidentally do all sorts of things to get them in trouble. This has included but not limited to using the navigation arrows, jumping off to read their email in the same window as the form and returning to a dead forms session, minimizing, resizing, blurring off to another window and then returning back by clicking on the title bar of the browser and wondering why the form doesn't tab etc.
Sure hobbling the browser by opening with limited functionality is a possibility but not a complete solution.
2) New versions of browsers seem to break something. Both IE 7 and Firefox 2 have their own problems with web.show_document, especially file associations such as CSV and DBF and trying to open things in Excel in IE7.Firefox seems to have less problems for some yet some some oddities like the one that started this thread (and 2.0 opening new windows in tabs by default instead of windows).
3) JVM jigsaw puzzle. Is it Jinit or Sun, which versions? Which combinations of browser version and JVM works.
4) General fragility of the whole architecture. Running a client JVM in a web browser on top of a PC Operating system connectiong to a forms server over a network embedded in a Java Container server on a full blown web server running on a unix operating system is pushing the bubble. Throw in the mix that any of these components can be combined in numerous ways makes one wonder how it works as well as it does.
Still users randomly getting dropped connections to forms server (network gltches?). General sluggishness (poorly written forms?). Periods of users with unduplicatable errors primarily network related it would appear.
General feel that it is not rock solid stable. Perusing metalink documents on performance and tuning gives too much and too general info to troubleshoot so just shrug shoulders and say 'network problem'.
What's the solution? Java webstart would seem to help at least with the browser realted issues but is that supported and documented how to use yet. Also we'd lose web_show_document which is critical (could it be replaced by webutil calls to open browser?).

CRM IC Webclient - Massive Performance Problems Searching in Agent Inbox

Hi Forum,
can somebody help me. We have massive Search Performance problems in Interaction Center Webclient in Agent Inbox. When agents searching, for example for open emails, the time to get a result takes approx. 2-3 minutes.
Thats absolute inadmissible and endangered the running business.
The queury reading the eMails from the workitem tables is very very slow.
Could somebody help me with ideas to solve this big performance problem. Have somebody the same problems?
Thank you very much in advance for any information.
We use Interaction Center Webclient on CRM Release 5.0
Thorsten

Another aspect you could check is the following:
Analysis performed didn't show anything strange nor any high consumers
of the response time. The processing time occurs, since IC-Web on CRM 5
is a bit demanding for CPU power.
The only thing that could improve the performance a bit is the
<b>buffering of org structure</b>, which is currently switched off for
SALES and SERVICE scenarios as per table T77OMATTSC.
The report <b>HRBCI_ATTRIBUTES_BUFFER_UPDATE</b> is running regulary
however no scenario is being placed in the buffer to speed up
org structure read. Please check this and provide feedback.
How to use this report, can be found back in the Reports own documentation and also in SAP HELP.
cheers

Performance problem using OBJECT tag

I have a performance problem using the java plugin and was wondering if anyone else was has seen the same thing. I have a rather complex applet that interacts with java script in a web page using the LiveConnect API. The applet both calls javascript in the page and is called by java script.
Im using IE6 with the java plugin that ships with the 1.4.2_06 JVM. I have noticed that if I deploy the applet using the OBJECT tags, the application seems the trash everytime I call a java method on the applet from javascript. When I deplot the same applet using the APPLET tag the perfomance is much better. I would like to use the OBJECT tag because it applet bahaves better and I have more control over the caching.
This problem seems to be on the boundaries of IE6, JScript, the JVM and my Applet (and I suppose any could be the real culprit). My application is IE5+ specific so I can not test the applet in isolation from the surround HTML/JavaScript (for example in another browser).
Does anyone have any idea?
thanks in advance.

Jdeveloper dual core processor performance problem

I have a dual core 2.4 ghz processor and 2 gig of ram and Im running Jdevloper 9.0.5.2 and my performace is terrible. Other developers in the company have non-dual core processors and they can start up in debug mode using the Jdeveloper embedded oc4j our application in 10 seconds where it takes me 4 min!!!!!

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,

"Oracle text" performance Problem

Architecture for Performance on a web site Search!
I wanna use text service of ORACLE.But I am worried about the performance ....
How should I design the system if I want the best perfomance and scalability ?
1.Should I build a seperate coloumn in my every table and merge all the information into one coloumn and full text index that column.
2.Put a full text index in all column in the table and use OR clause and reverse rank it for AND clause,using CONTAINSTABLE function.
3.Make a different table and put ID,TYPE and _VALUE fields and search in that table with less coloumns.
4.Seperate the full text database and search in a seperate db so that I can scale better?
did anybody have a similiar problem ? Any books on full text search ?

The number of indexes is irrelevant as such. If you really need 100 tables and you really need full text search on all of them, you need 100 indexes. When you are inserting data in any given table, the fact that there are 99 other tables with 99 other Text indexes is irrelevant.
That being said, I would seriously question whether a data model that involves doing full-text searches on 100 separate tables was actually a proper data model. That strikes me as highly unlikely.
