I am experiencing a problem when I am profiling an application server in MyEclipse. I configured the VM so I could profile it and launched the profiler. The application starts up properly and the VisualVM window displays. I selected the “Take a snapshot of collected results” button and received an error popup:

Not enough memory to save the snapshot

To avoid this error, increase the -Xmx value in the etc/netbeans.conf file in NetBeans IDE installation.

Of course I am not running NetBeans so I have no idea where to set the memory flag. Do I set it on my executing application or is there a configuration file in MyEclipse that I should update.

Any assitance would be greatly appreciated.

Ernie,
Can you give some more information?
1. Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Details?
2. Are there any errors logged in the log file located at workspace dir > .metadata > .log?
3. Can you list out the steps in detail to replicate the issue?

You can try changing the values of -Xmx in the myeclipse.ini file located in your installation directory (~\Genuitec\MyEclipse 8.x Latest\myeclipse.ini). Please make sure the value is not too high. In some cases where the value is too high, it could be silently ignored by the VM.

Let me know if that helps.

Shalini,

Here is the information you requested:

1. Data from Installation Details

*** Date: Wednesday, March 24, 2010 12:30:36 PM PDT
** System properties: OS=WindowsXP
OS version=5.1.0
Java version=1.6.0_13

*** MyEclipse details: MyEclipse Enterprise Workbench
Version: 7.5
Build id: 7.5-20090609

*** Eclipse details: MyEclipse Enterprise Workbench
Version: 7.5
Build id: 7.5-20090609

2. Errors in the Workspace .metadata .log file
The errors I saw listed did not appear to be directly applicable to the memory error and all occurred before the memory error was encountered in my testing. However, as you requested the information, it is listed below:

Regarding your suggestion about bumping up memory, I don’t think altering the memory will make any difference. When I received the error, the Eclipse process was consuming around 500 MB, well below it’s 720MB maximum. I would have also thought that the VisuaVM was running in it’s own Java process and was not sharing heap with MyEclipse.
