Memory Profiler in Jdeveloper 10g

Is there any tutorial/article on how to use the memory profiler in jdeveloper 10.1.3.4?

I have the same problem. I am using ADF with JClient, locally deployed.
And I have also noticed that after approx 5 or 6 commits (i.e. when I insert a new record, enters its values and then commits, and repeats these steps 5-6 times) the memory consumption is radically increased and finally the computer is running out of memory.
I really hope that these problems will disappear in the production release of JDev 10g.

Memory Profiling OPMN changes

When I add the -agentpath option specified in the JDeveloper document to configure the remote memory profiling in Oracle 10g Application server's opmn.xml I get following error "Unrecognized option -agentpath..." and the server does not start.
Has anyone successfully configured the application server to perform remote profiling?

Thank you, shgoel, you're right.
We replaced the default JDK 1.4 with JDK 1.5 (in the directory D:\Ora10gas\as\jdk\ to be precise)
We moved the profiler DLL to the JDK bin and used the -agentlib option instead of the -agentpath (not sure if this change was significant, though)
To the Java start-parameters in opmn.xml we added the profiling port and a pointer to the profiler-agent.jar.
The resulting Java start parameters where:
-server -Xrs -Xmx512m
-agentlib:profiler15=port=4627,jarpath=D:\jdev\lib\profiler-agent.jar,enable=m
-Dmic.system.home=d:\mic_home
-Dmic.j2ee.home=D:\Ora10gas\as\j2ee\OC4J_MIC\applications\mic
With these settings we where able to connect remotely with JDevelopers memory profiler and resolve a memory leak.
Thanks

Memory profiler disabled in JDeveloper 10.1.3.3.0.4157?

Hi,
I'm using JDeveloper 10.1.3.3.0.4157, and it seems that the memory profile is disabled in this version. Or isn't it? How do I enable it?
Thanks in advance!

Make sure your project is using the OJVM.

Remote Memory Profiling

Can anyone tell me how to set up remote memory profiling in TP4? The existing instructions for 10g do not address remote profiling. At one point I somehow found documentation on a profiling agent that is started from the command line but I cannot find that again. Anyway, I really need to profile a Tomcat application server, and it would be nice if TP4 could do the job. Maybe this type of thing would even convince my colleagues that JDeveloper is better than Eclipse or IDEA.
Thanks In Advance, Keith

'Cmon Team JDeveloper - in a matter of a few hours, I was able to download and setup NetBeans and start remote profiling my JDeveloper-developed web app on Tomcat. Surely somebody knows how to do this with JDeveloper!?
I'm a long-time JDeveloper user and a very vocal proponent of the tool - I pains me to have to use another tool to do what JDeveloper should clearly be able to do. Heck, I'm willing to help document the process if someone can just help get me going on this.

How to do memory profiling remotely???

Hi,
We are using JDeveloper 10g (10.1.2.1.0) and Oracle Application Server 10g (10.1.2.0.2) to deploy our web application, its running on a Solaris OS. We would like to know how to make a remote memory profiling for this configuration. JDeveloper help is very ambiguous, and very short.
Anybody could help us a little bit with this? How we can configure OC4J JVM to attend remote memory profiling requests? How we can connect and run the JDeveloper memory profiling extension over this OC4J JVM?....
Thanks in advanced.

Nice to read it ;-)
Any other option to profile memory remotely on Solaris and OC4J JVM? Maybe any JDeveloper plugging or any standalone recommendable product? Or I could thinking in cutting my veins already?
Thanks for your answer.

Unable to run Memory profiling, help please

Hi there,
I installed the lastest version of JDeveloper 10 and created a very simple project(only have one class with Main()method) for testing purpose.
I configure the Profiler in Project Properties page, setting the class as included instance, however, all those profiling menu items(e.g.: Memory Profile...) are greyed out and I am unable to run memory profiling.
I wonder if the functions are available for the free-downloaed version of JDeveloper, or is there something wrong with my setting?
Your help is highly appreciated.

Make sure you are positioned on the class in the application navigator before going to the "run" menu option.
Also does it work if you don't change anything in the project properties?
Here is what I did - created a new project with a simple hello class. And I didn't had any problems profiling it.
There is no function limitation on the version you downloaded.
Here is the class I tried:
public class Class1
public Class1()
public static void main(String[] args)
Class1 class1 = new Class1();
System.out.println("hello");
}

Jdev11g CPU profile and Memory Profile doesn't work for Mac

I'm running Jdev11g on Mac OSX 10.5.5,
CPU Profile and Memory Profile doesn't work. I got following message:
Error occurred during initialization of VM

The file actually is there. I don't understand why they looking for .so file, it supposed to be mapped as .jnilib on Mac.
This is broken on TP4 as well.

I'm still seeing this issue. Here is what I get:

TP4[BUG]: Memory profile and CPU profile doesn't work for MAC

I'm using Mac OSX 10.5.4.
When I try to use Memory profile and CPU profile, I got following error:
Error occurred during initialization of VM
Could not find agent library in absolute path: /Shared/jdevstudiobase1111/jdev/lib/profiler15.so
But the file actually exists.

My MAC version is OSX 10.5.4.
I don't have a stacktrace. It just fails silently.
You can easily reproduce this bug by reformat a readonly file.
Here is the code I reverse engineered from oracle.jdeveloper.refactoring.util.Util.java:
public static boolean setReadOnly(java.net.URL url, boolean readOnly)
boolean ret = false;
java.lang.String cmdarray[] = null;
java.lang.String platformPathName = oracle.ide.net.URLFileSystem.getPlatformPathName(url);
java.lang.String osName = java.lang.System.getProperty("os.name", "");
if(osName.startsWith("Windows"))
cmdarray = (new java.lang.String[] {
"ATTRIB", readOnly ? "+R" : "-R", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
else
if(platformPathName.equalsIgnoreCase("Linux"))
cmdarray = (new java.lang.String[] {
"chmod", readOnly ? "u-w" : "u+w", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
if(cmdarray != null)
java.lang.Runtime runtime = java.lang.Runtime.getRuntime();
try
java.lang.Process process = runtime.exec(cmdarray);
if(process.waitFor() == 0)
ret = (new File(platformPathName)).canWrite();
if(ret)
oracle.ide.model.Node node = oracle.ide.model.NodeFactory.find(url);
if(node instanceof oracle.ide.model.TextNode)
oracle.ide.model.TextNode textNode = (oracle.ide.model.TextNode)node;

Hello Frank,
Thank you for your suggestion. I tried that and I got the same error. Looked more careful at it:

I tried to execute it manually:

Did
$ chmod a+x /my/home/data/opt/jdeveloper/jdev/bin/ojc
which solved the execution. Now Hello word works.
I got jdeveloper as a .zip archive, which doesn't keep unix permissions. The Linux distribution should be in .tgz archive, it would have avoided this problem.
Thanks!

How to create .ear file in JDeveloper 10g

Hi, I am new to Jdeveloper. I am using JDeveloper 10g. I have created one project abc.jws under which there are five .jpr folders(DTO.jpr,persistence.jpr,service.jpr,util.jpr,ViewController.jpr). I want to create .ear file for the whole project so that it can be directly put in the production environment. When I right click on the abc.jws and select New, the EAR option under deployment profiles is disabled. I would highly appreciate if someone can help me on this.
Thanks.

Any solutions from oracle to improve Performance in Oracle Jdeveloper 10g

Hi ,
We are developing ADF Applications in Oracle Jdeveloper 10g , 4 developers are working . now every one M/c Ram upgraded to 4 GB
Still my developers are getting Performance issue , Like Java Heap memory Reached . when we saw in Task Manager Memeusage reached 450,000K
then Jdeveloper dies and hang there . we have to do this at least 4 to 5 times everyday . thats where it taking a lots of time to
modify a single small changes .
What our deveoper are doing they trying to commit frequently after making a important changes in application . but sometimes developer are also
forget in between . So wee need a solution for this if Oracle fixes this issue .
Thanks
KP

Hi,
We never had that issue with 10g (but happens in 11g), what is the project's size? I assume very big, else your environment must have something fishy, 10g is really fast and lightweight.

Memory Profiler

getting the following error in Jdev 11.1.1.7 when tryin to memory profile my viewcontroller:
Error occurred during initialization of VM
Could not find agent library C:\SOA\Middleware\jdeveloper\jdev\lib\profiler_x64.dll in absolute path, with error: Can't load IA 32-bit .dll on a AMD 64-bit platform
any ideas?

As the error message says, you are running on a 64bit platform and the menroy profiler trys to load a 32 bit dll for the profiling. Not sure if there is one for a 64 bit platform, but this should be mentioned in the doc for the memory profiler. Check the doc for system requirements.

Memory leaks in JDeveloper?

Hi,
I have created two entity objects for two tables in Oracle database. In windows task manager, I started watching the memory usage for "jdevw.exe". When I keep clicking back and forth on the two entity objects in the navigation window, I see that the memory usage going up with every click. I watched it going from 70MB to 130MB until I stopped clicking.
Is this a known bug?
Product: JDeveloper 10G (preview version build 1375)
OS: Windows 2000 w/512MB RAM
DB: Oracle 8.1 running on the same PC
Hope it helps.
Raju

I have the same problem. I am using ADF with JClient, locally deployed.
And I have also noticed that after approx 5 or 6 commits (i.e. when I insert a new record, enters its values and then commits, and repeats these steps 5-6 times) the memory consumption is radically increased and finally the computer is running out of memory.
I really hope that these problems will disappear in the production release of JDev 10g.
