I successfully installed Yellow Dog Linux 6.2 on Sony PS3. Then I installed the IBM Java VM: ibm-java-sdk-6.0-5.0-linux-ppc.tgz. I couldn't start the IBM JVM 6 the first time. There was some error, so I had to install libstdc++5.0-3.2.2-24565cl.ppc.rpm. I found the needed rpm by using a rpmsearch web-site.

Then I unzipped Ontotext KIM and set the path to the IBM JVM in the /kim/bin/config_machine.sh and it worked (because I had already made some fixes to KIM).

I had to set Yellow Dog Linux to runlevel 3 to free memory. Also YDL uses the unused video RAM as swap space automatically. This theoretically means that the PS3 has 256MB + 256MB Video RAM resulting in total 512 RAM. I have also set 1Gb disk swap space during YDL installation and I think the Video RAM swap file is used with higher priority than the disk based one. I also set KIM to use 440Mb of RAM in /kim/bin/config_kim.sh: export KIM_MAX_JAVA_HEAP="440m". The default is "1g". When connecting to KIM from another machine I also had the usual problems with JAVA RMI. I also decided to turn off the YDL firewall.

KIM works quite slow. It's like 10 documents for 30 minutes. This is due to the supervisor from Sony under which Linux is running. Then comes the really low amount of memory.

Anyway it was fun and proved that I am a geek

I am investigating whether I can run Linux and Ontotext KIM on the Play Station 3. As far as I see I need the IBM Java VM.

Looks like Fedora 11 install under PS3 just fine. More here

Officially KIM supports only the Sun JVM. I have tried the KIM platform under the IBM Java VM on a 32-bit Fedora 11 on Intel machine. I have downloaded it from IBM web-site. The archive name is: "ibm-java-sdk-6.0-5.0-linux-i386.tgz". I also did fix a potential problem in my Relations framework in the development version of KIM 3.0 thanks to using the IBM JVM.

1. There seems to be a bug related to incompatibility with older com.thoughtworks.xstream.XStream and IBM Java VM: http://jira.codehaus.org/browse/XSTR-379

The resolution is to replace the current XStream 1.2 with the current XStream 1.3.1
We did that today in the main-stream KIM 3.0 dev version.

2. The line:
KIM_OPTS="$KIM_OPTS -Xshare:off" in KIM_control.sh
prevents KIM from starting because "-Xshare:off" is not supported parameter from the IBM Java VM.
The resolution that allowed KIM to start is: KIM_OPTS="$KIM_OPTS"
I have modified the KIM bash scripts to resolve this problem.

Fixing these two problems now allows KIM to start normally with IBM JVM and it should also work with PowerPC version of the IBM JVM(32-bit iSeries/pSeries). The archive for the Play Station 3 should be "ibm-java-sdk-6.0-5.0-linux-ppc.tgz".

OpenJDK also starts KIM just fine and seems to work for now.

Also keep in mind that officially Ontotext KIM does not support non-Sun VMs.

Now the only missing piece is the Play Station 3 itself.
