Profiling OC4J on Linux

I want to profile portlets, web apps and EJBs in OC4J on both Windows & Linux (more specifically, Suse Linux). Specifically I'm interested in profiling of memory (where are most objects created) & performance (in which method does the application spend most of its time). Does anybody have any experience with this?
From two tools I know of, Borland's OptimizeIt (http://www.borland.com/optimizeit/) only supports Red Hat Linux (http://info.borland.com/techpubs/optimizeit/optimizeit55/textfiles/support.html) and OC4J on Windows (http://info.borland.com/techpubs/optimizeit/optimizeit55/textfiles/appserver.html). JProbe (http://java.quest.com/jprobe/jprobe.shtml) supports only Red Hat as well (http://java.quest.com/support/jprobe/platforms.shtml) and isn't too specific about its OC4J support (http://java.quest.com/support/jprobe/j2ee.shtml).
I know that the JDeveloper has a built-in profiler but it seemed a little simplistic (how can I compare any two memory snapshots) and sparely documented. And from what I know, it can't do remote profiling on the server.

You can install OJVM on Linux see:
http://www.oracle.com/technology/products/jdev/htdocs/9.0.5.2/readme.html#ojvm_install_linux
And you might also want to try installing 10.1.3 on linux and using it for profiling.

Thank you AndrewThompson64
You have done a great job.You are welcome.. but really, the only
'great' thing I did was a quick search on
'Java install linux'
to show that link (that I knew was around
here somewhere) at the top of the
search reasults!
Thanks for your interest to help me.You are welcome. :-)
Next time you get stuck, 'drop back by'* and
I'll show you some more clever search tips. ;-)
* ..but really, you will gain a lot if you simply
'lurk' around the forum and read other posts,
even as you are writing code..

Unable to Start OC4J in Linux

Hi
We tried to start oc4j in Linux using following command
[oracle@fa2220 setup]$ oc4j -start
Starting OC4J from /dbfiles/home/oracle/obiee_home/OracleBI/oc4j_bi/j2ee/home ...
It is stopping at this stage without any errors.
Linux Version: Red Hat Enterprise Linux Server release 5.3 (Tikanga)
We tried to see what is being done in the process, so we did strace and found the following:
strace -p 15924
Process 15924 attached - interrupt to quit
futex(0xb7675bd8, FUTEX_WAIT, 15925, NULL
And we checked the netstat –a | grep 23791 (default ORMI port) and found it is listening on this port.
But we can not access oc4j.
Can someone please help?
PS

I managed to solve the problem by setting the "Load All System JAR Files during OC4J Startup" in the "Embeded OC4J Server Preferences" under "Global > Startup".

OC4J on Linux RedHat 8.0

Hi I want to know whether the OC4J which we use on Win2k is the same for Linux RedHat 8 or do we have to download a diff version?? If so where can I find that?
Or how to install OC4J on Linux RedHat8
Thanx
Kulkarni

I just unzipped oc4j_extended.zip into /usr/local/ and then started it like:
cd /usr/local/j2ee/home
$JAVA_HOME/bin/java -jar oc4j.jar &
Then exited my shell (which bash lets me do)

Memory profiling oc4j application on linux

Is there any way I can use Jdeveloper's memory profiler to connect to an application running in oc4j on a remote linux server? I don't see this as being possible because it seems to require ojvm which isn't available on linux. Am I wrong? What are my alternatives? I really need to profile my memory usage on this server.

You can install OJVM on Linux see:
http://www.oracle.com/technology/products/jdev/htdocs/9.0.5.2/readme.html#ojvm_install_linux
And you might also want to try installing 10.1.3 on linux and using it for profiling.

Running OC4J on Linux in the background?

I am relatively new to Linux and have been trying to start OC4J either automatically or as a background process (so that I do not have to keep the terminal window open). I tried "$nohup java -jar oc4j.jar &", but OC4J still shuts down when I logout or exit the terminal. Does anyone know of a good way to start OC4J automatically or as a background process?

You've two choices:
- install public domain 'screen' program followed by
running oc4j in a 'screen' session and detach from
the 'screen'. BTW, 'screen' allows you to reattach
to an existing session of 'screen'
- Write a one line shell script and launch this script
in the background. Now when you exit from your shell
your oc4j will continue to run.

How to start OC4J at Linux boot time

Hello,
I am using Linux AS 3.0 and i have installed OC4J ( 9.0.4) ok, and OC4J also work fine.But each time i want to start OC4J , i must execute command java -jar oc4j.jar at console.
Now, I want to start OC4J automatic at System startup ( ie: Linux boot time ).How can i do?
Thanks.

Just put your OC4J start/stop commands in a rc script.
Scripts in the directories
/etc/rc.d/rc2.d
/etc/rc.d/rc3.d
/etc/rc.d/rc5.d
will be called by the operating system with the command line option start.
The number in the directory names represent the desired run level of the machine.
Scripts in the directory
/etc/rc.d/rc0.d
will be called during shutdown with the command line option stop.

Starting oc4j on linux

I am using RedHat Linux 7.2 and ias 9.0.2. When I try to execute java -jar oc4j.jar, it hangs and never returns. It is also not opening a port. The log file says that it started. What should we do or look for?

Hi Bob,
You can try running OC4J in "debug" mode. The following web page has
details:
http://kb.atlassian.com/content/atlassian/howto/orionproperties.jsp
By the way, did you try searching the forum archives before posting?
I have posted the above URL several times already in other posts. Are
you already familiar with the above URL? Did it not help you?
You can also execute the following command:
java -jar oc4j.jar -help
Should show you some other, available options.
You can also add "-verbosity 10" to the command line, for example:
java -jar oc4j.jar -verbosity 10
Hope this helps.
Good Luck,
Avi.

OC4J in Linux OS Errors

we have developed an Enterprise Java Bean for OC4J (version 9.0.2.0.0) which is running on Win2000 OS without any bugs.
when we deployed the same EAR file in OC4J (version 1.0.2.0.0) on linux OS.we r getting an error like this---->
java.lang.InstantiationException: Illegal use-caller-identity value, legal values are True and False.
Is there any problem with the change in OC4J version or
due to the change in the OS.
Anyone pls help us to sort out this problem.
thanks
prabakar & team.

Prabakar,
This is because of the version.
OC4J 1.0.2.2.1 does not have support for <use-caller-identity which is part of EJB 2.0 spec. This works fine with OC4J 9.0.2 that supports most of the EJB 2.0 spec.

Deploying to OC4J on Linux

I am tring to deploy to a Linux server, however I get the following error message:
Error in CreateMarlinUIXPage.createUITree: no protocol: /uix/ClientPage.uix
The application works perfectly fine using OC4J localy on my windows box. I have tried zipping the entire app and manually deploying however this doesn't work either. If some one could point me in the right direction I would appreciate it...

Here is the error messages from my oc4j:

Problems with CDC/Foundation Profile making on Linux, heip me please!!!

I am a new to J2ME.My OS is redhat9.0,and building tools is gcc3.4.3.After having downloaded the cdcfoundation-1_0_1-fcs for linux, I unzip it to /home/cdcfoundation/.Under the directory of /build/linux/,I typed the following command:
make CVM_JAVABIN=/usr/java/jdk1.5.0/bin CVM_DEBUG=true J2ME_CLASSLIB=foundation
But it failed to build,the error is:
make: *** No targets specified and no makefile found. Stop.
I had tried many times,I hope someone can help me!!!
I am waiting................

You need ksh (korn shell) in order to compile. It is because this shell provides an option (if I remember well -h) which is not present in other shells like bash.
So, download it from http://www.kornshell.com and make it available in a folder present in your PATH.
Hope this help.
