Hi Support Team,

Could you please tell me what i need to do to fix this error?. I’m not sure if i increase VM (ie java_opts / catalina_opts) arguments would fix the problem. First i would like to know what is the reason for this error?. Not becos of enough memory for eclipse / sandbox tomcat server / system physical memory. Which file exactly i need to increase eg myeclipse.ini or catalina.bat?.

or

Is this due to J2EE Application using spring & hibernate?. It’s happening in the last couple days when i select certain modules in my web based application. Sometimes i shut down the server, sometimes my eclipse says stack trace error and quit the MYeclipse.

Eagerly looking for a permanent solution to this problem. Thanks in Advance. Please mail me if you need any further details.

Chitra,

The issue is often not the heap itself but the Perm space for classes. Please try these startup arguments:
myeclipse.exe -vmargs -Duser.language=en -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M
Or you can modify MyEclipse.ini file and update the above vmargs values.

Hi Joy,

Sorry for delay in reply.

I tried the parameters you mentioned still i get the same outofMemeory: java heap space error in my sandbox tomcat server. Also pls explain me what is the difference between Integrated Sandbox tomcat server and Tomcat Server (TC5.X,TC6.x). Do you think my application is big for Sandbox TC server to handle? That is the reason for Error?. Can you pls suggest whether can i deploy the application on to TC6.x (the one in external). My application is using (J2EE Technologies)spring-hibernate-sybase DB.

Waiting for your reply.

Thanks,
Chitra.

Chitra,

I assume you see that stack trace in the console when you try to start Tomcat? In this case you may need to add more memory to your Tomcat process, not MyEclipse. You can do this by going to Window > Preferences > MyEclipse > Servers > Integrated Sandbox > MyEclipse Tomcat > JDK. In the Optional VM Arguments section you can try adding

-Xmx512M

Sandbox Tomcat is a customized and integrated version of Tomcat 6, you could just as easily have used an external Tomcat 6 instance too – you would need to add the same customization as described above to it too.
Hope this helps.

Hi Brian,

I made changes to Tomcat VM arguments as you mentioned , so far i don’t have any problem, hopefully i don’t want it happen anymore.

Thanks Brian.
