Re: [ptp-dev] Fixing Error 'Failed to create the Java Virtual Machine' - on Windows
I ran a test with the RC3 build on 32 bit Windows XP. I had to reduce the -Xmx setting to -Xmx900m. Once I did that I was able to start Eclipse.

I created a synchronized project, edited a coupe files, built the application, ran it using the PE resource manager on AIX, ran a simple LoadLeveler resource manager test and a simple LSF resource manager test. The corresponding monitoring views were also used.

No problems found.

OK that build (win32) works for me on a WinXP machine with 1.43 GB of RAM
(The same machine did indeed fail with the Error  'Failed to create the Java Virtual Machine' on RC3)

Other experiences?

I think the upper limit for me is about 900M with the SR2 RC3 build, determined by trial and error. Beyond that I get the popup. I did get SR2 RC2 to start once at 1024M. I'm not sure this is a problem anywhere other than Windows XP 32 bit. I don't have access to Windows 7 32 bit to try this.

although, i think Dave said that he had to go down to 768 to get it to work. So some folks are still going to get it....

(Sorry, I've been away all afternoon and evening.)
Yes there's something about SR2 that makes the 2G setting for win32 not work any more.

I tend to agree with Markus in that an eclipse that won't even start is confusing for new users.
I think for win32 systems with a lesser amount of memory(?) that the error now means that using realistic-sized synchronized projects isn't going to work.
But I'd rather they see an out of memory exception when they need more, rather than the error we now have, and it won't start.

I think Markus' suggestion makes sense to try.  Wish it weren't so late in the cycle.
Can you build tomorrow first with this as you suggested please, Markus? Win 1G, others 2G. Thanks.

The first thing most people do with the parallel package is try to create a synchronized project. Unfortunately for a project of any reasonable size, this will require over 1G, hence the reason we chose 2G as the default. I would prefer that at least the linux and macosx packages remain at this level.

Hmm, thanks for the Mr. package... but I don't know a real solution.

The current settings with 2GB are in place since Juno SR1 (see bug 389517) and I agree that this seems a bit high.

In the .product file this can be set for all platforms or for specific platforms only (i.e. restricted to linux, macosx, windows), but it is *not* possible to restrict it to an architecture (e.g. x86 or x86_64). It might be possible to specify it in this granularity in the p2.inf file, but I never tried to add this kind of argument there.

One solution could be to remove these VM arguments from the 'all platforms' section, and apply individual settings to the different platforms like the example below. Note that I chose a different, lower value for windows.

<launcherArgs>
<programArgs>-product org.eclipse.epp.package.parallel.product
--launcher.defaultAction openFile</programArgs>
<programArgsWin>--launcher.XXMaxPermSize
256M</programArgsWin>
<vmArgs>-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard</vmArgs>
<vmArgsLin>-XX:MaxPermSize=256m
-Xms512m
-Xmx2048m</vmArgsLin>
<vmArgsMac>-XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts
-XX:MaxPermSize=256m
-Xms512m
-Xmx2048m</vmArgsMac>
<vmArgsSol>-Xms512m
-Xmx2048m</vmArgsSol>
<vmArgsWin>-Xms512m
-Xmx1024m</vmArgsWin>
</launcherArgs>

If I were you I'd try to use a lower value, e.g. the 1024 MB, instead of the 2024 MB for all platforms. I believe that users are used to modify this value in the eclipse.ini if they are running into out-of-memory, heap, etc. errors, but users are not familiar with an application that doesn't start at all. In my opinion that's the worse case and leads to a very bad first impression.

Markus

Markus, we are seeing several win32 testers not being about to launch on WinXP win32 without bumping down the

We didn't see this in the previous release (SR1)

I just bumped it down in epp.product from  the default -xmx 2048 to 1024, maybe we need 768, but i notice that cpp's is even lower, 512m.
Advice???  
Lower might be safer so at least new users can bring it up.  an OutOfMemoryException later would lead you to increase it later, at lease.

What do you think?

I also commented on the bug, I can get it to run with 512m and 1024m for -Xmx, I think it's just a memory allocation request compared to what the machine actually has available. The default is 2048 (kinda high for a 32 bit machine which can only utilize 4gb max).
