From MidrangeWiki
The Portable Application Solutions Environment, or PASE, provides a subset of AIX functionality on the iSeries.
This can be used to port a number of traditionally unix only capabilites to the iSeries.
Information on PASE can be found at http://www-1.ibm.com/servers/enable/site/porting/iseries/pase/
In V5R4, the 32bit version of the JVM runs in PASE.
