Jeremy Bauer closed OPENJPA-737.
--------------------------------
Assignee: Jeremy Bauer
Resolution: Won't Fix
I spent a bit of time on this issue several weeks back. I was able to get
around the OOM and severe performance problems by:
* Upgrading to YDL 6.2 which include a kernel module to add a high priority
256M swap area mapped to high speed VRAM
* Adding a 2GB swap partition on an external USB 2.0 disk
* Using a remote MySQL database - eliminating disk I/O to a local Derby DB
* Using the 32-bit IBM SDK, which uses less heap
A build with jUnits was still terribly slow (20+ hours) due to the lack of core
memory. In addition, Sony recently pulled the plug on their "Other OS" support
as of firmware rev 3.21. While OpenJPA may prove to work fine within an
application on this platform (pre-3.21 fw), it doesn't look to be a suitable
for development. Closing this JIRA.

> Key: OPENJPA-737
> URL: https://issues.apache.org/jira/browse/OPENJPA-737
> Project: OpenJPA
> Issue Type: Bug
> Components: build / infrastructure
> Affects Versions: 1.3.0
> Environment: Playstation 3, Yellow Dog Linux 6.0, IBM Java SDK 5.0
> SR8a ppc64, 768mb swap space
> Reporter: Jeremy Bauer
> Assignee: Jeremy Bauer
> Priority: Minor
>
> The OpenJPA build fails with an OutOfMemoryException on Playstation 3 while
> running unit tests. I end up with a large core dump and other debug files.
> The build is successful when I disable the unit tests. Is there a way to
> run the build+unit tests on machines with limited memory (256mb core)?
> BTW, I have yet to get an OutOfMemoryException or javacore from Metal Gear
> Solid. An OpenJPA build should be a piece of cake. :-) :-)
