Java Profiler for RMI Applications

I am looking for a profiler to monitor the bottlenecks and the memory usage when running my RMI application.
What would you recommend to use and a comprehensive tool

Couple of thoughts on scaling:
1. Change the mx setting to 1200m -- this is the most you can scale a single instance on 32-bit
2. Use a 64-bit platform you can set memory settings really high (AIX/Solaris)
3. Multiple servers with planning on it using a load balancer

Java Processes for Planning Applications

Hi There,
We've experienced performance issues where we have reached the limit of the java process for Hyperion Planning - WAS element. My question! Is it possible to create multiple java processes for Hyperion Planning, for example: If we have 7 Planning applications could we have 7 Java processes running - one for each application?
Thanks
Mark

Java profiler for AMD64 on Eclipse

Does anyone know of a profiler that would work with Eclipse for profiling a 64 bit application on an AMD64 Opteron system?
Thanks,
Harsha

To make it work a little better (but 100 times slower ;-) turn off hotspot
and jit!!!

Yes,
It is more stable than the others -- doesn't crash sometimes for 10minutes
but it's not enough for me to collect performance data but I am still
trying so eventually I might be able to gather some.
I keep getting
# HotSpot Virtual Machine Error, Unexpected Signal 11

# Problematic Thread: prio=5 tid=0x2a3328 nid=0x8 runnable
but since without the profiler settings I do not get the problem I am
unable to say what happens and the behaviour is not consistent --sometimes
the JVM crashes at WLS startup sometimes later.

[Solved] How to use Oracle Java 6 for specific applications

I use an IDE called PyCharm. On its download page, it recommends using Java 6 instead of OpenJDK. I currently have jdk7-openjdk installed, and from what I had read in the Arch Wiki on Java, it should be possible to install Oracle Java 6 along side OpenJDK 7.
However, after installing jdk6-compat and jre6-compat, I still see that I am running OpenJDK 7 when I run the following:
% java -version
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (ArchLinux build 7.u9_2.3.3-1-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
...even after I have set JAVA_HOME and added /opt/java6/bin to my path.
How can I get PyCharm (or other applications) to use Oracle Java 6 instead of OpenJDK?
Thanks, and apologies if I've posted in the wrong place.
Other information that might be helpful:
Running zsh as default shell
Using Gnome 3 as DE

I found the solution.
For Pycharm, I just needed to add an environment variable PYCHARM_JDK. For running specific applications, I asked this question on the Unix / Linux StackExchange and got an answer there.
Also, after running PyCharm in Java 6... I would not recommend it. OpenJDK works fine

Unable to generate Skeleton for RMI application

Hello Friends,
I used one interface and implementation class to invoke RMI they are as follows
package com.rmi;
import java.rmi.Remote;
public interface CountRMI extends Remote {
     public int sum() throws java.rmi.RemoteException;
     public void sum(int _val) throws java.rmi.RemoteException;
     public int increment() throws java.rmi.RemoteException;
package com.rmi;
import java.rmi.server.UnicastRemoteObject;
import java.rmi.*;
public class CountRMImpl extends UnicastRemoteObject implements CountRMI {
     private int sum;
     public CountRMImpl(String name) throws RemoteException{
          super();
          try{
               Naming.rebind(name, this);
               sum=0;
          catch(Exception e){
               System.out.println("Exception:" + e.getMessage());
               e.printStackTrace();
               public int sum() throws RemoteException{
                    return sum;
               public void sum(int _val) throws RemoteException{
                    sum = _val;
               public int increment() throws RemoteException{
                    return ++sum;
Implementation class, when I compile both and run rmic CountRMImpl I got the following error,
public class CountRMImpl extends UnicastRemoteObject implements CountRMI
^
Error is stated at CountRMI
please help me to over come this.
Thanks,
Bhargavi.

package com.rmi;
public interface CountRMI extends java.rmi.Remote {
public int sum() throws java.rmi.RemoteException;
public void sum(int _val) throws java.rmi.RemoteException;
public int increment() throws java.rmi.RemoteException;
//Three methods to implement later ok
-------------------------------------------------javac----------------------------------------------------------------------------
package com.rmi;
public class CountRMImpl extends java.rmi.server.UnicastRemoteObject implements CountRMI
private int sum;
public CountRMImpl() throws Exception
super(); //it will call the constructor of the UnicastRemoteObject
sum=0;
public int sum() throws java.rmi.RemoteException
return sum;
public void sum(int _val) throws RemoteException
sum = _val;
public int increment() throws RemoteException
return ++sum;

I think we need to write the rmiRegistry Application
But after compiling the below iam able to generate only the stub not the skeleton i dont understand why it is. But it is working whenever i use the Registry application i.e given below
public class Myregistry
public static void main(String args[]) throws Exception //Exception is RemoteException , bind so on
CountRMImpl c1=new CountRMImpl();
java.rmi.Naming.bind("uniquename",c1);
System.out.println("Hey binded the object CountRMImpl to the Registry");
now we need to run the rmiregistry first then check whether i.e binded correctly or not
start rmiregistry
java Myregistry
output: Hey binded the object CountRMImpl to the Registry
I asks the experts in the above every thing i got success but what happend to the skeleton that is not created by the command "rmic"
please give the information why

Java Card for healthcare applications

I am quite new to Java Card and I am currently developing a healthcare applications using Java Card. What is best:
Storing the patients medical history on the card itself
OR
storing it on a database and use the Java Card as a access token?
Thanks.

Besides the fact that the storage capacity of todays JavaCards is very limited. This question is IMHO more a plitical question (and a question of privacy) than a technical question.

[Java]Java Library for CVS and SVN

Hi!
I need Java libraries for my application. I want to manage repository CVS and SVN directly form Java code and not with a graphic interface.
I've found some SVN library(for example SVNKit) but I don't found any CVS library.
Can you help me?
Thanks,
Stefano.

Keep googlin'! They're out there! It's worth grabbing the source code for Eclipse or NetBeans or something, and digging about in there. If they're not using a third-party library to handle CVS, they've probably at least written their own. Nothing to stop you, for instance, grabbing part of the Eclipse Team bundle and using it yourself.
Question is: Why do you want to do this? If it's some wacky "self-checking in code", forget it.

Java.security.AccessControlException in a RMI application

Hello,
I have the following error, while I'm launching my RMI application :

java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)

at java.lang.SecurityManager.checkConnect(SecurityManager.java:1044)
at java.net.Socket.<init>(Socket.java:262)
I was trying the following instruction :
if (System.getSecurityManager() == null)
System.setSecurityManager(new RMISecurityManager());
try{
Recepteur obj = new Recepteur();
Naming.rebind("//localhost/Recepteur", obj);
However, I have written in the java.policy file :
grant codeBase "http://127.0.0.1:1099/-" {
permission java.security.AllPermission;
Does anyone know how to solve this problem ?
Thx

Help him please or he would be obliged to give me the dukes...
