Java 1.4.2 in Linux with a 2 processor Server

We want to install Linux Enterprise ES 3.0 into a 2-processor Server PC.
We are going to use this Server as an Oracle Application Server with
the above software installed.
Is there any problems-conflicts with
1. java_1.4.2
2. Linux ES 3.0
3. Oracle Application Server 9.0.4 Enterprise Edition ?
I only ask because i read of some Linux kernel problems with java 1.4.2
and Servers with 2 processors.
Regards,
John,
Greece

How is the 2 cpu system performing? Do you see any problems?
We use more or less the same config but we have slow network io performance.
As we have 2 exact the same machines I switched one of them to Fedora Core 1 kernel 2.4.22
the system regularly freezes ...then switched to fedora core 2 final (kernel 2.6.5) using java 1.4.2_04 and _05.
Everything freezes after some time starting up a jvm. The only thing that still works is responding to pings.
How is your network I/O performance?

Java running under linux with crontab

I'm having a problem:
i want to run a java program under linux with crontab.
my classes are in a directory and aren't in a package. i run em by invoking ./start which is a small script that i wrote. The script is in the same dir as the classes and invokes java by "java Main >>logjava.txt " but this doesn't seem to work all i get is an empty logfile
i need to run the program every day at 0800 so i inserted the following in crontab:
0 8 * 1-5 /var/"path"/start > logjava (where path is the path to the classes dir)
if i run the cmdline from anywhere on the prompt i get the result i want. I think it's because the cron runs it from the root dir thus making java unable to find the classes
Any suggestions would be welcome. or can some1 tell me how to make linux executables from the java (i usually use jsmooth for the windows exe)

You can execute several commands in the process started by cron. You separate them using semicolons.
Have you tried a cron entry like this:
0 8 * 1-5 cd /var/"path";pwd;echo $PATH; ./start > logjavaOr, you may need to make sure the process started by cron gets the same environment as your interactive shells do, by explicitly loading your setup or .login scripts:
0 8 * 1-5 . $HOME/.setup;cd /var/"path";pwd;echo $PATH; ./start > logjava

JMenuBar display quirks with some window managers on Linux with Java 6

When I run this code on Windows with Java 5 or Java 6, it works fine.
When on Linux with Java 5, it works fine.
When on Linux with Java 6 in KDE, it works fine.
When on Linux with Java 6 with twm or e17, the JMenu shows when I click on the JMenuBar, but goes away as soon as I release the mouse button. If I manually move or resize the window, it then works fine.
If I remove setLocationByPlatform(true), the menu bar works, but it does not position the window by platform, which is the desired behavior.
Am I doing something wrong, is there something wrong with both twm and e17, or is this a bug?

                    Test test = new Test();
}

In 10.1.3, there's an option to disable the splash screen on the Environment Page in preferences (although, of course, it's not much use if you never get to the main window because of the dialog popping up behind the splash screen... :) )
The bug with the dialog appearing behind the splashscreen is fixed in the upcoming 11g release. FWIW, it's a problem that appears to be unique to X-based systems, where for some reason the splashscreen window ends up with some super-ueber topmost property that forces all other windows to go behind it.
There's also a command line flag to suppress the splashscreen in 11g.
Thanks,
Brian

Please help me how to solve this issue.

I suggest trying to install a different version to confirm the error. Do you have SELinux enabled? It can cause weird errors. You can check the syslog /var/adm/messages to see if there were any SELinux errors.

Analysing SAP Java Memory Usage in Unix/Linux

Hi,
I need to analyze the SAP Java memory usage of Unix /Linux machine..NW 7.0
Please guide with the commands and steps..complete prcedure.
Based on it I should decide whether to create a new server node (or) increasing heap size
Thanks in advance

Hi,
Do you have performance problems?
How many CPU's are in the server?
Did you check Log Configuration for delays or errors?
Did you tune any exisiting parameters?
You can add the nodes only if there is performance problems. You may think of adding one node to start with
Proper number of server nodes within an instance:
u2013 #ServerNodes = availableMemory / (JavaHeapPermSpaceStack)
You can calculate the server nodes based on below formula
No. of server Node = (RAM you want to assign or available RAM in GB)/2.5 ============> for 64-bit system
No. of server Node = (RAM you want to assign or available RAM in GB)/1.5 ============> for 32-bit system
Hence as per above discussion, we should go with 5 server nodes means,
5 = RAM/2.5 (Assuming you are on 64-bit platform)
i.e. RAM = 12.5 GB
2). u2013 Configure JVM heap according to Note 723909 and Note 1008311 - Recommended Settings for NW 7.0 >= SR2 for the AIX JVM (J9)

Java Runtime on top of Linux Kernel?

Hi all,
Im trying to illustrate a concept (demo) where i can run a dedicated java app on top of my linux development kit.
Im having no luck. I can develop C based app's in eCos and 'download' the app through serial connection from PC to Linux Dev Kit.
I would like to run a Java app (ME) on my Linux Dev Kit, is this possible? I mean, can I get the Java Runtime to work with an embedded device?
I couldn't find a similar topic on the forums (Ive probably not looked hard enough) could anyone point me in the right direction.
Many thanks
Harry.

You can certainly use JNI. You will have to (in your code) somehow specify which C++ libraries to load for which system. For example, for windows, load xxx.dll, for hpux, load xxx.sl, etc. I don't know how to find the operating system in Java, someone else might be able to reflect on that.

HELP: Java Install on RedHat ES3 Linux

I get the following error evoking java after initial install of J2SDK on RedHat ES 3 (version 9):
[root@bdln4002 ~]$java -version
Fatal: Stack size too small. Use 'ulimit -s' to increase default stack size.

I have adjusted the stack size via ulimit command and reloaded the kernel. I have extended the stack size to "unlimited" and still receive the same error. My current settings look like this:

I have installed Java plenty of times in Solaris with out a fraction of this frustration. Any ideas where I am missing the boat? My searches are turning up nothing ... so assume I am complete linux idiot at this point.

I've never heard of that error before. So I googled it and found this..
http://www.mail-archive.com/[email protected]/msg15491.html
Are you using a Blackdown jvm.. That isn't necessary for Linux any more. And the suggestion in this thread is to try using Java version 1.5. Honestly, I don't know enough about this subject to offer any thoughts of my own here.
For general help with Linux you could try Linux Questions. There is a forum there specific for Red Hat users.
http://www.linuxquestions.org
Here are some links which offer information about installing Java on Linux. I don't remember the dates on these pages.

Compare Linux with Solaris

We have tested the I/O performance on Intel-Solaris 7.0 and Intel-RedHat Linux.
We found that Intel-Linux has much better performance than Intel-Solaris.
Now, we are thinking to install Oracle 8i on Intel-Linux.
However, before we make this decision, we would like to hear more opinions about
the advantages and disadvantages of running Oracle on these two different
operating systems. We'll appreciate, if you can give me your opinions.
Thanks

This from experience of running large-db ecommerce site on intel linux with redhat 6.1, oracle 805 and 8i, with some java functions, intermedia, time-series module, 4 different servers on aolserver 2.33 and aolserver 3.0 on 1 machine: it's stable.
I never had a crash, and no locking or restarting due to either aolserver or oracle.
With a few minor modifications in linux to support some enterprise functions (raw devices, async io) linux on intel with oracle is almost ready to kick sun's ass. (at least on the 1 to 8 cpu server market)

Java Performance on Jaguar vs Linux and Windows

Hi All
Sometimes ago I heard that Java apps gain performance improvements running on the Mac OS X platform and the IDEs are more responsive on Mac OS X compared to Windows and Linux.
I'm going to buy a new notebook and now after 10 years of having experience of using PCs I have the opportunity to buy a PowerBook if I find it reasonable. Indeed, I'm a university student and because of that it doesn't matter that which IDEs are available for Mac OS X or not. The only thing important to me right now is the performance (compiling, executing, and...).
Does any body have any idea on the performance of Java on Mac OS X vs. Windows or Linux?
Thanks in advance,
bye.

Windows is the fastest, hands down. If you get a top of the line desktop replacement laptop, then you will get the best performance. If that's all you care about ,then get that and put windows on it. Don't bother with linux as the video drivers are bad compared to the Windows ones.
However, being a recent mac convert, I would not say that the mac is a bad choice. It has netbeans and it's own IDE (project builder). It's fast enough for work. Just make sure you have 512MB+ of ram, though I'd say the same for windows XP. Also, you'll be able to make apps that use the native OS much easier with the Mac as opposed to windows. Since all the tools come for free with the mac, you have to buy MSVC to use things like JNI. Unless that is you like using the borland compiler.
As a dev platform, a new Mac running X is supreme. It's got real unix, and it's got an awesome toolset. You can go and design GUIs that work with only writing minimal code. Cocoa is amazing, especially because it works with Java instead around it.
If you are looking for max speed, Windows. X86 based pc's are also better because there are more out there so you get more software and support. Linux is nice, but I still don't think that it's a good laptop OS. Love it for servers though. With OSX you get all the desktop features that are missing from linux, with all the unix you are missing from Windows.
Besides, how many operating systems do you know where all you need to do to install MS Office is to copy it from the CD? (to run it you need a key though :)

Running a Java program at startup in Linux

Hello
How do I run a Java program at startup in Linux? I know in Windows I can put a .bat file in C:\Windows\Start Menu\Programs\StartUp\ directory, but in Linux I have no idea how it is done.
Thank you,
Mihai

This is really a Linux question, not Java.
And then it depends on the version of Linux you are using.
Maybe this will help, otherwise you should try on a forum for your version of Linux.

Oracle10g Installation problem on Linux with DHCP IP

Hi,
I am new to Oracle Products, I have tried to install Oracle 10G on Linux with DHCP IP.
I got the following warning while installing even though I have loopback interface configured.
Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned public IP addresses. However, the primary network interface on the system should be configured with a static IP address in order for the Oracle Software to function properly. See the Installation Guide for more details on installing the software on systems configured with DHCP.
Please help me in resolving this problem or Can I ignore this message?

This warning means it is not recommended to install Oracle 10g on a DHCP assigned IP address. It could work, but you won't be able to configure Enterprise Manager, since this tool requires a fixed IP address. If possible, have the IP address fixed.

10g Grid (RAC) on Linux with ASM and OCR?

I was trying to install 10g on Linux with ASM. The docs are not terribly clear on this, but I'd like to have the Oracle Cluster Registry (OCR) on one of my four ASM disks, rather than dedicate space to OCFS. I have 4 18.2 GB drives setup with ASM now. Is there a way to do this?
I guess the other thing I could do is to cut the ASM disks into two partitions. One, say 200MB and the other the rest. I'd put OCFS for OCR on the 200MB partition on one of the disks. The large partition on each of the rest of the disks would be dedicated to ASM.
What am I missing? I feel it must be something obvious. I'd rather have the OCR on the ASM, so that I don't have to deal with it...
Thanks!
Jeff

Hi.
There shouldn't be a problem with this provided you use a 32-bit OS on the 64 bit machine. RAC doesn't care about the chipset, so long as the same OS is used, but I don't thinkit will support one node on 32 bit and one on 64 bit, since they are actually separate distributions.
Of course, I've never tried it so I can't be sure :)
Cheers
