OpenSim 3.3 JVM startup error
Hi,
I have installed OpenSim 3.3 on several windows xp computers we have here and on attempting to start OpenSim I get the following error 'JVM creation failed' - the software then doesnt start.
Could anyone advise on a way around this?
Thanks
Sarah

Re: OpenSim 3.3 JVM startup error
Hi,
We've seen this error particularly when trying to run 32 bit distribution on 64 bit machines due to memory management issues of the JVM. The solution(s) are:
1. If on 64 bit machine, better use the 64 bit distribution.
2. If you need to run the 32 bit distribution on 64 bit machine (for Matlab or any other reason), please close a few other applications as the JVM needs a large contiguous block of memory to start. Having many processes running even if the physical memory is huge can cause the memory to fragment and the JVM to fail to start.
3. There're options to customize memory management of the JVM but these are hard to tune though you can look them up and modify the settings in the .conf file as needed.
Hope this helps,
-Ayman

Re: OpenSim 3.3 JVM startup error
Hi Ayman,
I am installing the 32 bit version on a 32 bit machine so that isnt the issue. No other applications were open but I guess there may have been processes running in the background limiting the memory.
At some point I will attempt your option 3 and see if I can solve the problem.
For now I have installed OpenSim 3.2 which seems to be working fine.
Thank you for your help!

Re: OpenSim 3.3 JVM startup error
Hi,
I had the same issue running Windows 7 64bit where I'm using 32bit OpenSim for Virtual Studio and Matlab coherence.
I solved it (so far) by installing 64bit JVM and editing the ../etc/opensim.conf to point at the 64bit jvm as seen is this snippet from line 10:
So far it looks like it's working.
I'm afraid that this solution does not apply for your case, when you are running x32 OS but I wanted to post it in case others could find it useful.
However, regarding Ayman's 3. alternative, I found this page that gives a little more info and shows you how to try it out.

#jdkhome="jdk"
jdkhome = "C:\Program Files\Java\jre7\bin"

Re: OpenSim 3.3 JVM startup error
If you are still having problems with the JVM startup error, try starting OpenSim with less heap space. You can do this by modifying the options when starting OpenSim.
Can use any text editor to modify opensim.conf (probably located at C:\OpenSim 3.3\etc\opensim.conf)
original:
default_options="--branding opensim -J-Xms24m -J-Xmx1024m -J-Dsun.java2d.ddoffscreen=false -J-Dsun.java2d.gdiblit=false -J-Dsun.java2d.noddraw=true -J-Duser.language=en"
example modification:
default_options="--branding opensim -J-Xms24m -J-Xmx512m -J-Dsun.java2d.ddoffscreen=false -J-Dsun.java2d.gdiblit=false -J-Dsun.java2d.noddraw=true -J-Duser.language=en"
Lowering the heap space may cause problems later if OpenSim needs more memory, but I haven't had any issues yet.

Re: OpenSim 3.3 JVM startup error
thank you very much Hoa. your suggestion worked for me.
fyi, i am running opensim on 32bit xp with 1G ram.

this is work in Windows 7 32 bit

Re: OpenSim 3.3 JVM startup error
Hi
I installing opensim 3.2 (23 bit) on windows 7 (32 bit). the installation process was successful. but when i run the program, the JVM creation error was appeared.
what should i do now???
