Thread related issue in Application Server

I have one application talking with different hardware devices like reader to read RFID Tag Data or continuously update status of the RFID printers and print Tags.
This application runs on lots of THREAD.
And it is running as a seperate unit as a standalone Java program.
Now I want to deploy this unit in the application server.
Is it creating any thread related problem If I deploy the same application in side the application server ?
Please help me.

Is it creating any thread related problem If I deploy
the same application in side the application server ?Yes, lots of them. App servers might not like applications to create their own threads, since those would not be covered by the internal resource-mapping mechanisms. Your thread might end up without available resources after a context switch.
Websphere 4 certainly pukes. 3 was rather tolerant in these regards IIRC.

URGENT: WS data control - Issue in Application server 10.1.3.3

Hi All,
I created a ADF web service data control and used that data control in an ADF JSPX page. When I tested the page in JDeveloper 10.1.3.3 (Embedded OC4J) it worked fine. But when I deployed the same in Application Server 10.1.3.3. it shows the following exception:
javax.faces.el.EvaluationException: oracle.jbo.JboException: JBO-29000: DCA-40012: Failed to create a connection to the Web Service
Similar issue is already posted in the following threads:

There is bug (ID: 5878326 ) raised in Metalink for this. I applied the patch 5878326 as mentioned in the Metalink. But after applying the patch also, the same exception occurs. I deleted connections.xml and then recreated, but no success.
I also tried to create a new web service data control and used it in a new ADF JSPX page, again it shows the same exception in App Server 10.1.3.3.
But the bug in Metalink is closed. Please let me if anyone is facing the same issue and the solution for this.

Please post ADF related issues to the JDeveloper forum -- ADF is a runtime that gets installed on the app server, so the ADF folks are the most likely of all to be able to be of help.

Performane related issue in Production Server

Hi,
when i deploy the whole application in development server (by remotely logging into client server through vpn) it works fine .
But when it is run at client side for system testing, user acceptance testing and
integration testing it becomes very slow .
Due to this performance related issue , we are not able to transfer the DCs to production server .
We are sure it is not coming from R3 side (BAPIs etc) . It is coming either from the Webdynpro or Portal side .
Can anybody help out regarding how to solve this issue .
Thanks .

Hi Narendra,
Please elaborate what is QAS customization and production customization.
TR has been done properly.
Let me give you an overview of the project.
In Organisational Assignment a Zprogram has been written which captures additional information like Grade Code, Designation Code & Pay Sheet Code
Its a govt. client. Combination of Grade Code & Designation Code is Pay Scale Grouping
e.g if Grade Code is A01 & Designation Code is A005
Pay Scale Grouping is A01-A005
If we put the values in 0001(Org Assignment) for Grade Code(A01) & Designation Code(A005), A01-A005 comes automatically in Pay Scale Grouping for a particular Pay Scale Structure.
But now the problem is Pay Scale Type doesn't come get defaulted in 0008 for a Personnel Area & Personnel Subarea.
I have maintained PST in Tariff & Check Assignment of Pay Scale Structure in Enterprise Structure.
But in 0008, We have to put PST manually. Since client is having only 1 Pay Scale Area for all Personnel Area & Personnel Subarea, so we don't have to bother for it
Please tell me where can be the error
Regards,
Usha

Any issue with application server on 32 bit and database server on 62 bit

Hi Experts,
Please confirm that application server on 32 bit and database server on 62 bit will not cause any communication related performance issues between the servers ?
Thanks
Raman

Hi Anurag,
the .Net server for BPC 7.5 NW and the app/web server for BPC 7.5 MS can both run on either 32- or 64-bit server OS. However my understanding is that they are still 32-bit processes and as such have the same limitations on 64-bit windows as they do on 32-bit (in particular the addressable RAM limitation at 4 GB)
Note, and this is important, that this is for version 7.5 only. The BPC 7.0 MS web/app server HAS to be on 32-bit OS.
Best regards,
Bruno Ranchy

Install PeopleTools 8.53 with Linux Issue: Boot Application Server Domain PT853 using psadmin

Folks,
Hello. I am installing PeopleTools 8.53 Internet Architecture. Database Server is Oracle Database 11gR1. OS is Oracle Linux 5.
I confront the issue regarding booting Application Server Domain PT853 while Database Server is listening as below:
[user@userlinux PT8.53]$ . ./psconfig.sh
[user@userlinux appserv]$ export SYSTEM_PASS=SYS/SYS
[user@userlinux appserv]$ export ORACLE_HOME=/home/user/OracleDB_Home
[user@userlinux appserv]$ export ORACLE_SID=PT853
[user@userlinux appserv]$ export TUXDIR=/home/user/Oracle/Middleware/tuxedo11gR1
[user@userlinux appserv]$ export LD_LIBRARY_PATH=$TUXDIR/lib:$LD_LIBRARY_PATH
[user@userlinux appserv]$ export PATH=$TUXDIR/bin:$PATH
[user@userlinux appserv]$ ./psadmin
Its output gets 2 errors in the current server log file /home/user/psft/pt/8.53/appserv/PT853/LOGS/APPSRV_0919.LOG as below:
First, GenMessageBox(200, 0, M): PS General SQL Routines: Missing or invalid version of SQL library libpsora64 (200,0)
Second, GenMessageBox(0, 0, M): Database Signon: Could not sign on to database PT853 with user PSADMIN.
I create a symlink in /home/user/OracleDB_Home/lib and /lib32 as below:
[user@userlinux lib]$ ln -s libclntsh.so.11.1 libclntsh.so.8.0
[user@userlinux lib32]$ ln -s libclntsh.so.11.1 libclntsh.so.8.0
After that, I run ./psadmin to boot the domain PT853 again, I see the first error is solved. Now, there is only one error in the current server log file /home/user/psft/pt/8.53/appserv/PT853/LOGS/APPSRV_0924.LOG is below:
GenMessageBox(0, 0, M): Database Signon: Invalid user ID or password for database signon. (id=MyOwnerName)
Server failed to start
I have changed UserId as PSADMIN in Configuration file, purge cache and clean IPC resources and reboot. Password is correct. But the error always indicates id=MyOwnerName.
Application Designer login as PSADMIN successfully. Data Mover Bootstrap login as MyOwnerName successfully.
My question is:
Why both PSADMIN and MyOwnerName are invalid user ID or password for database signon ? How to solve the issue ?
Thanks.

As stated in the installation manual there are a few prerequisites in chapter CHAPTER 8B Configuring the Application Server on UNIX page 238
Prerequisites
Before beginning this procedure, you should have completed the following tasks:
Installed your application server.
 See "Using the PeopleSoft Installer," Understanding PeopleSoft Servers
Installed Tuxedo 11gR1
 See "Installing Additional Components."
Granted authorization to a PeopleSoft user ID to start the application server.
 The database configuration procedure includes a step for setting up the user ID with authorization to start
 the application server. See the application-specific installation instructions for information on the user IDs
 for your PeopleSoft application. See the PeopleTools: Security Administration product documentation
 for information on PeopleSoft PeopleTools delivered user profiles.
 See "Creating a Database on UNIX," Running the Database Configuration Wizard.
 See "Creating a Database Manually <on Windows or UNIX>," Creating Data Mover Import Scripts.
Run the following SQL statements on your database server to review and if needed, update the PSCLASSDEFN table:
 SELECT CLASSID, STARTAPPSERVER FROM PSCLASSDEFN
 WHERE CLASSID IN (SELECT OPRCLASS FROM PSOPRCLS WHERE OPRID='<OPRID>');
 UPDATE PSCLASSDEFN SET STARTAPPSERVER=1 WHERE CLASSID='<CLASSID>';
Note. Installers typically use VP1 or PS to test the application server. If these users are deleted or their
passwords are changed, the application server will no longer be available. To avoid this problem, you can set
up a new operator (called PSADMIN or PSASID, for instance) with privileges to start the application server.
If you do this, you can use the new operator for your servers and you won't need to change the
password each time VP1 or PS is changed.
Does you user have privileges to start the applications server.
Also pay attention to the connectid configuration in the application server. This should be the same connectid and password as you provided during the database creation script connect.sql

Install PeopleTools 8.53 with Linux Issue: Configure Application Server using psadmin

Folks,
Hello. I am installing PeopleTools 8.53 Internet Architecture. Database Server is Oracle Database 11gR1. OS is Oracle Linux 5. I have installed JDK7, WebLogic 10.3.6, Tuxedo 11gR1 and PeopleTools 8.53 successfully into Oracle Linux 5. I have set up PeopleTools 8.53 Database Instance into Oracle Database Server successfully. Data Mover and Application Designer login into the Database Instance successfully. Web Server has been configured successfully.
Now, I confront the issue regarding configuring Application Server as below:
In Windows, I run /PT8.53/appserv/psadmin.exe to create a domain for the PeopleTools Database Instance successfully. But in Linux, the file /PT8.53/appserv/psadmin is light blue color and not executable, I try to run it in the following way:
[user@userlinux appserv]$ ./psadmin
Its output: ./psadmin: error while loading shared libraries: libtrio64.so: cannot open shared object file: No such file or directory
My question is:
Can any folk tell me how to configure Application Server using psadmin in Linux for PeopleTools Internet Architecture ? How to solve the above issue ?
Thanks.

Folks,
Hello. Thanks a lot for replying. I run psadmin in the way below:
[user@userlinux PT8.53]$ . ./psconfig.sh
[user@userlinux appserv]$ export TUXDIR=/home/user/Oracle/Middleware/tuxedo11gR1
[user@userlinux appserv]$ export LD_LIBRARY_PATH=$TUXDIR/lib:$LD_LIBRARY_PATH
[user@userlinux appserv]$ export PATH=$TUXDIR/bin:$PATH
[user@userlinux appserv]$ ./psadmin
For Application Designer login, I use UserId PSADMIN and password PSADMIN, it works successfully.
For Data Mover Bootstrap Mode login, I use UserId MYNAME and password MYNAME, it works successfully.
When configure Application Server, I use UserID PSADMIN and password PSADMIN. But when boot the domain, the current server log file "APPSRV_0919.LOG" indicates that "Database Signon: Could not sign on to database PT853 with user PSADMIN."
Then I use UserId MYNAME and password MYNAME to configure the Application server again. I boot this domain again. Strangely, the log file APPSRV_0919.LOG gets the same error message "Database Signon: Could not sign on to database PT853 with user PSADMIN."
I purge the cache and clean IPC resources of this domain, and boot this domain again but get the same error message as above.
The content of current server log file /home/user/psft/pt/8.53/appserv/PT853/LOGS/APPSRV_0919.LOG is below:

2) I purge the cache and clean IPC resources of this domain and reboot this doamin, why the log file APPSRV_0919.LOG gets the same error message "Database Signon: Could not sign on to database PT853 with user PSADMIN." ?
3) How to solve the above issues ?
Thanks.

Are threads in the application server preemptive?

Are threads in the application server preemptive or non-preemptive? That is do
they automatically yield to other threads running in the application server after
they have run for a certain amount of time or do they only yield when certian
points in the code are reached (eg when they have completed, when they reach a
remote call or when they explictly call yield()).

Green threads (way back in 1.1.8 and so on) was Unix only, and non-preemptive.
It was also very lumpy and unreliable. Old threading tutorials used to recommend
calling yield() and suitable points in your code - just like Windows 3.0 all over
again.
But all current JVM implementations use OS threading, and are pre-emptive (but
of course that doesn't stop them being blocked due to synchronization or I/O etc...)

Regarding Application server file path browsing

Hi All,
I have a issue regarding Application Server File Path browsing.
Actually in my selection-screen i will declare a parameter as Application Server File Path now when i press F4 in that field it should be able to browse through Application Server Path's.
Just like F4_FILENAME in the case of Presentation Server File Path Browsing.
Can anybody solve my issue.
Thanks in advance.
Thanks & Regards,

Hi Shaik,
Just copy and paste:
Here is the code for retrieving list of files contained within specific Application server directory(SAP).
PARAMETER: p_fdir type pfeflnamel DEFAULT '/usr/sap/tmp'.
data: begin of it_filedir occurs 10.
include structure salfldir.
data: end of it_filedir.
START-OF-SELECTION.
Get Current Directory Listing for OUT Dir
call function 'RZL_READ_DIR_LOCAL'
exporting
name = p_fdir
tables
file_tbl = it_filedir.
List of files are contained within table it_filedir
loop at it_filedir.
write: / it_filedir-NAME.
endloop.
Hope this will help you.
Let me know incase of any concerns.
EDIT:
There are few FM for ur refernce :
RZL_READ_DIR_LOCAL
SUBST_GET_FILE_LIST Return table with file list for the given directory (pattern allowed)
F4_DXFILENAME_TOPRECURSION Popup to select one file from the given application server directory
TH_SERVER_LIST Returns list of application servers.

Oracle Application Server 10g thread stuck issue.

We are having,
Oracle Application Server 10g [10.1.3.1 + 10.1.3.4patch] along with Oracle Http Server 2.0
Now there is a issue of thread stuck [some application threads taking longer times] due to which the application server is unable to respond and sometimes it reinits the oc4j instance.
=> Is there any setting to increase the Thread Stuck Time in OAS.
=> Is there any setting to stop the auto reinit of oc4j instance.
=> Does the auto re init of oc4j get logged in opmn.log as well as in service.log.
It will be really helpful if any advice on the same.
Thanks in advance...

Look in httpd.conf file anything that is like thread in there you will find a simple description of the Directives.

Oracle Application server related issue

My application is developed using Oracle Developer suite 10g (10.1.2.0.2 ) and deployed in Oracle Application Server 10g R2 (10.1.2.0.2) in windows 2003 32 bit and its working fine.
My issue is as follows
1. Since Oracle Application Server 10g R2 (10.1.2.0.2) is not supported in windows 2008 64 bit, pls advise what version of Application Server 10g i should use. Please note that my
programs are developed using Oracle Developer suite 10g (10.1.2.0.2 ).
2. If i want to move to next development version (ie forms / Reports 11g) , which version of application server should i use.
Joe

The 2nd disk is Companion CD. It contains the install files for other components.
For instance, If you want to install Oracle HTTP Server only, then you use the companion CD to do so. It has many other individual installations.

3. Is the JDBC Driver Platform Independent?
4. Can we separate OC4J Servlet engine(Web Container) from
Oracle 9i Application

5. What other Servlet engine is compatible with Oracle 9i
Application server?
and finally ...
we are developing application with Oracle database in Sun
Solaris 2.8 OS
and after development we have planned to change the oracle

Oracle BIEE installation issue: Application Server default OC4J name error

Hi all,
I am installing OBIEE 10.1.3.3.2 windows 32bit version on windows 2003 sp2. Before the installation I have installed the JDK 5 and Application Server 10.1.3.1.0(J2EE Server and Web Server) on the same server according to the pre-install section in the OBIEE installation guide.
When I install OBIEE (advanced installation), I got the error when I specify the Oracle Application server location:
Please specify a valid Oracle Application Server 10g installation location. A valid Oracle Application Server 10g installation must have the default OC4J instance named home and that home OC4J instance must be enabled.
When I install the Application Server 10.1.3.1.0, I have change the default OC4J name to "oc4j-soa", I think this is the root reason I got the error. I have tried to create another OC4J instance named "home", but failed coz the name is used for another directory.
Then can I have another way to continue the installation? Why OBIEE installer have this strange constrain while not any words about this issue in the installation guide (coz I follow the each steps in the guild before I take action)? I have search some threads and the only information is to install a simple installation, but it would create another application server..... and the simple installation type is not what I want.
Can anybody give me some hint or information about this issue? otherwise I have to purge and reinstall the server...... Thanks
Scott

Reinstalling the App Server and naming oc4j instance to be called "home" resolves the issue but this is an odd requirement. I have an OC4J instance already running and it is named something else. Is there any other alternative to make this work?
Swapan.
PS. I can always create a new oc4j instance named "home" but this is wasting of server resources.

Application Server issues when running in EC2

I have deployed a war file to the app server on an Ubuntu machine running in Amazon's EC2. The application starts up, server logs are redirected to a custom log file, and everything seems to run fine. However, shortly after starting up an exception shows up in the log file that appears to be significant, and logging dies even though the site continues to run. The exception in the log file is below. I have other Ubuntu systems on which this does not happen. Any thoughts on what the problem might be?

Hi Ilya,
You know that this forum is to discuss the VS Debugger tool, not the real development forum, so to really repro this issue and make sure that whether it is the VS issue or the project issue or others. Could you share us a simple sample with One drive? I
will debug it with the same Environment as yours.
If you have other VS machine, please also debug it again. But if it still has this issue, I doubt that it would be related the specific project.
>>Now, the weird thing is when I run the same Windows Forms app directly from the build folder without Visual Studio or in Visual Studio without Debugger (Ctrl+F5), it works fine!
Please clean and rebuild your project, and then re-click the .exe in build output folder, does it still work normally?
If you add breakpoints in your code, and then debug it, after the breakpoint is hit, you could use the option "Step Into(F11)" to debug the code one step by one step, maybe it is related to the specific line code.
If you get any information, please feel free to let me know.
If still no help, please also attach your Visual Studio project, you can upload it to the one drive, and then share the download link in your post. Please also attach a screenshot image in your post.
If there's any concern, please feel free to let me know.
Sincerely,
Jack

ST03 Visualization Issue - Application Server Missing

Hi Gurus.
I've a strange issue related to the Workload analysis.
When I call transaction ST03N I see in the the workload only the Central Instance.....Application Server is missing.
I've checked the SAPWLSERV table and both server are listed here.
What I'm noticing is that no entry are found in table SWNCMONI nor in SWNCMONIINDEX.
Well, it's not correct at all...I found an old entry of last february, but nothing more!
Already checked the time_zone also....everything seems to be corretly configured.
Any Ideas?
Thanks in Advance,
Marco

Problem seems to be with report : RSSTAT98 ,
Check the following notes:
Note 966309 - Contents of table TCOLL in SAP_BASIS 700 (schedule of report RSSTAT98)
Note 1135491 - RSSTAT98 - Inconsistent host name when setting up SAPWLSERV
If it was visible earlier and vanished one fine day , pls let us know if there was any kernel upgrade performed?
