Slow performance of Application server with a 9i database.

I am experiencing extremely slow perrformance of my 1.0.2.2.2 Application Server portal with my 9.0.1.2.1 database.
After logging in it takes forever just to connect to the Portal home page and even longer using the navigation link to connect to 'my pages'.
This degradation of performance pretty much happened over night. One day it was fine and the next it seemed to hang on every movement.
My server is running on Win 2000 with 1 GB of RAM. I ordered another GB of RAM hoping to alleviate a little of the congestion. I think it must hhave something to do with all the indexes, but I don't know how to tune the DB for it.
Does anyone have any idea of how to tune the DB to work with the Application Server portal? I am developing this portal for a client and I hate to think what will happen when it becomes fully rolled out and robust.

I tried to do a simular thing, but I did not notice a performance decrease. However it might be possible that this happens. For example, if you are calling a time critical vi in the second while loop, it will lock all other processes until it is finished. Or maybe you are calling a shared resource (allocate an array, access to a file, using a mutex) that the other loop holds. Until the shared resource is released the first while loop must wait before it can access that resource (memory, file, etc.).
Without looking at the source code it will be hard to say what is causing it. I recommend to remove part by part subVI's from the second loop, to debug where the problem exists. If you want I can have a look at the code, please reply to this thread.

FIle Creation in the Application Server With Unicode-8 and Byte-Order Mark

Hi Guys,
I've requirement of creating a file in the Application server with the Data.
The Data Format Should be in UTF-8 and Byte-Order Mark.
I need to supply this data from SAP to PRMS.
I'm able to create a file with Unicode, but any of the guys have worked on Umicode with Byte-Order Mark, please let me know.
Thanks,
Adi.

Hi Mathieu,
If you haven't found an aswer yet, you can check in transaction SE24 CL_ABAP_FILE_UTILITIES method CREATE_UTF8_FILE_WITH_BOM. You can check the code of the method (it's very short) so you can understand how it works. It's also a static method so you can call it directly in your program.
Ex:
CALL METHOD cl_abap_file_utilities=>create_utf8_file_with_bom(your_file_name).
I hope this helps.
Pax Vobiscum.

Upload a csv file in application server with the specified codepage(Poland

Hi,
i want to upload a csv file in application server with the specified codepage ( for poland ) , please let me know how to use open dataset for that.?
Anurag

I would upload the file with transaction CG3Z in binary mode and do the code page translation with a report: read from server an save with different name.

Very slow performance jclient when running with remote server

We have performance problems when running a JClient application, if the Application Server is on a different machine in the same 100mbit network. In our application we open 6 panels with about 15 TextFieldBindings each, on a tabbed pane. Each panel has it's own viewobject on the server. It takes the panel allmost two minutes to start up. Our own code seems to perform reasonable, but between the last line of code and the actual visibility of the panel there is a long period of low intensity network traffic between the client and the server machine, while both machines have low CPU usage. We tried setting the synchmode of the ApplicationModule to SYNC_LAZY and SYNC_IMMEDIATE, but this does not seem to make any difference.
It seems as if the server starts throwing a lot of events after our code is executed, which are caught by the BC4J controlbinding listeners. The performance is a lot better if we have the server and the client on the same machine, and the database on a different one.
This kind of performance is not acceptable for this application. Are we doing something that should not be done with BC4J, or are we missing something?

This kind of performance is not acceptable for this application. Are we doing something that should not be done with BC4J, or are we missing something? You must be hitting a performance issue regarding download of all property metadata for setting labels etc. on the UI (in case of remote-tier deployment).
This issue has been resolved for our next release of JDeveloper. Basically a new api has been added that allows 3tier apps to "download" the set of "used" VO definitions, Attribute Definitions etc on the client, so that the UI comes up quick.
Also a application/ui/binding load code-generation has been modified to allow for "lazy" loading of controls/lazy binding etc, quite like what's done in the JClient Control-bindings sample on otn.
For 9.0.2, you may shorten the "load" time, by loading only the UI that's first displayed and pre-loading ViewObject definition. However it'll still be slower than what the above mentioned method would do in one roundtrip.

Slow Performance When Application is Slow

We have an application that unfortunately appears to eat up system free memory over time. When the load increase and memory decrease we also see that all queries against Oracle slow down dramatically doing a lot of physical reads. (Oracle runs on a separate server from the application.) When we restart the application memory is freed up on the application server and Oracle queries run very fast. However, over time they both slow down again. Again, we only restart the application not Oracle.
Does anybody have any idea why a slow application would result in slow query times? We measured the slowness and it is indeed all in the query execution. Any help would be appreciated.
Thanks,
Steve

when you execute it from toad, do you get all the rows back, or just a screen full and call it quits? if you don't actually page through all the rows, then they aren't really returned, and oracle wouldn't need to do as many reads.
 
you can also check v$sql to find out if both toad and your application are really using the same sql. perhaps there's an "alter session set current_schema" going on somewhere that is changing things (granted, it's probably not that, but my point is that it could be something).
 
maybe toad and the application have different optimizer modes (all_rows vs first_rows) which result in a different plan, and therefore different amounts of physical read.
 
you can try these scripts from my blog to check "What is actually running right now?". Start with the CURRENT_SQL script to get the address and child number of the running sql. even if two connections run the exact same sql statement, there could be differences (mentioned above) which would result in different children.

Create directory on SAP application server with blanks

Hi,
is it possible and if so how to create within ABAP a directory on a Linux based SAP application server that contains blanks.
We've tested with SXPG_COMMAND_EXECUTE but didn't succeeded.
A working code snippet would be great.
Thanks and kind regards

Copy file on application server with codepage changed

Hello Gurus,
I need to copy an existing *.csv file on the application server to a different location as a *.txt file with the code page UTF-8 /8400/ in the background.
Example:
I have a file with the name is: 'new.csv' in the DIR: '/SERVER/NEW'.
I need to convert the file to 'UTF-8' and copy to DIR: '/SERVER/ARCHIVE' with the name: 'archive.txt'
I was able to get the file via FM: DX_FILE_READ into an internal table. Now I tried to use GUI_UPLOAD, but failed due to the fact the GUI_UPLOAD will just upload a file from PC to an internal table. Additionally I need to run the report in background. So the FG: SFES will not do.
Could you please give me a hint on this?
I am running in a circle
Any help will be rewarded.
Thank you!
Martin

Hello Atish, Satish
Thank you for the quick answer!
@Atish,
Your guide is very helpful and I have downloaded it for further use, however I do not need to make any uploads/downloads from and to PC in the background.
@Satish
The OPEN DATASET helped. This works in the background as well.
I have allotted points to both of you as promised.
Thanks again!
Sample of the code I used:
OPEN DATASET g_out_file FOR OUTPUT IN TEXT MODE ENCODING UTF-8.
LOOP AT lt_file INTO ll_file.
TRANSFER ll_file TO g_out_file.
ENDLOOP.
CLOSE DATASET g_out_file.
Where g_out_file is the path and file name and lt_file and ll_file are internal tables I retrieve by FM: DX_FILE_READ /type: dxrawdata/

Regarding writing file in application server with ISO8859 characters

Hello Experts,
I have a requirement that i need to write my file which read from the data base in ISO8859 characters in the application server.
Is there any FM or any particular code conver normal data base data to ISO8859 characters ?
Please give me some advise.
Thanks,
Suresh

Hello Suresh,
You DONOT have to do any conversion. You need to use the CODE PAGE addition with your OPEN DATASET stmt.
Can you specify as to which Character Set you need to download? (e.g., Cyrillic, Greek, Polish etc)
You can have a look into the SAP Note 73606 for details.
BR,
Suhas

Oracle report is not running on application server with more than 700 recod

Hi,
I have developed oracle report using dev suite report builder. When I am running using report builder then its running fine. Whenever I am deploying on application server and trying to run then its not executing. Then I have deployed same report with less than 700 records then its run fine.
Please advice me if you have any solution
thanks in advance
umesh

Hi Pavan,
Thanks for reply.
I have resolved this issue. This issue happen because of report server not able to handle large data. To resolve this issue I have made report server traces service off. Because of making traces off the report server fully utilized for report generation.
Thanks,

Is it possible to integrate a different application server with Creator

It's not love at first sight, but I think i'm gonna fall in love with creator. my question is, is it possible to use/integrate a different application server into creator instead of Sun's Application Server. I prefer to use Jonas

Alexis, thanks for your help -
The following was taken from the JRUN logs right after trying to deploy a sample Creator project called teta -
It works fine with the APP server provided with Creator.

JSK not starting application server with heap memory changes

Hi All,
I'm trying to configure the JSK 11gR1 on 64 bit windows 7 professional personal machine with 8 GB of RAM.
I have no trouble running JSK with default memory settings.
However, when i modified CATALINA_OPTS in Catalina.bat to maximum 1024 , application server is not starting .
Before
CATALINA_OPTS=%CATALINA_OPTS% -Xms384m -Xmx768m
After
CATALINA_OPTS=%CATALINA_OPTS% -Xms384m -Xmx1024m
This is the only change , however JSK is failing with error "Jump Start kit application server failed to start"
Any help would be appreciated.
Other options tried
1. CATALAINA_OPTS with -d64 option
2.Modified windows registry \System\CurrentControlSet\Control\Session Manager\SubSystems

Hi Sarath,
Is there a reason you would like to increase the memory size? JSK is intent not to be used for production but more for demo purposes.
I would suggest to do a full installation.
Cheers,
Rodney

Developing for a Oracle Application Server with SSO

Hello there,
I'm developing an application (Java) that will be deployed as a partner application within an Oracle Application Server 10g at my client. This Oracle instance has a SSO already configured, and my app will use this Identity Manager (consuming the cookie). The problem is that at my company we don't have a SSO system configured, not even an Oracle Application Server, just a simple Oracle XE 10g to hold data. So I'm wondering how can I do to develop my application and test it.
I was looking forward to install an OAS and configure an SSO to validate my implementation, but the download link provided by Oracle is broken (http://www.oracle.com/technology/products/ias/index.html). Another alternative that I thought of was to install an OC4J and configure a Java SSO to simulate the behavior of OSSO, and make my app the cookie set by it. But OC4J supports only til Servlet 2.4 and my app is using 2.5...
And to complete, I cannot access my client's environment. I'm supposed to write a Deploying document telling him how to deploy my app and then try to access it through Internet.
Does anyone have an idea of how can I develop and test my app in my company's environment?
Thanks in advance,
Bruno Krebs.

How to upload file on Application Server with Forms 6i?

Please, I need to upload .csv file from local to Application Server, I think to use .jsp application, but I don't know where I had to put it...Apache can't read .jsp file without Tomcat? If I launch my .jsp file from Apache/htdocs directory can't view .jsp code (Method Not Allowed)...method is POST...any idea? Thanks in advance!

Hi,
You could write a java bean to get the file from the client and to upload to App Server. And, you simply use it in Forms 6i.
Also, you could use d2kwutil (not tried though. you could search this forum and get an idea of that).
Of course, For your information, You could use WebUtil (in Forms 10g / 10.1.2) which has the functionality.
HTH.
