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?

SYNOPSIS


DESCRIPTION

       is  part of the Unwind Express Library for Integrity systems; see uwx(3X).  allocates and initializes a new callback info structure for use
       by the provided self-unwind callback routines in the Unwind Express Library.  The callback info structure is an opaque  structure  that	is
       used by several other entry points in the Unwind Express Library.

       A callback info structure, once allocated, may be used for many stack unwind operations.

       When the application is finished using the callback info structure, it should call to dispose of the memory used.

   Parameters
       env	      A pointer to an unwind environment object.

RETURN VALUE

       returns on success.  See uwx(3X) for error codes.
