My professional experience is to better stay clear from WPARs and use LPARs instead.

We have been setting up LPARs, in fact DLPARs, managed from HMC for our internal users. But on this particluar server, the physical configuration is too low to setup working DLPARs (The user had them procured without consulting us). So, we are setting up 2 WPARs on it.

I am assuming chroot from base server does not cause the compiler of one machine to affect the one on the other. Just like in Solaris Zones.

So, in any situation, would there be any compiler conflict between two WPARs running on the same base server?
