Are you sure that it is being terminated for 'paging space' and not because
you are out of heap?  I forget what the default heap is, but look into the
ulimit command (for ksh or sh).  To increase your limit, have the administrator
use smit to change your user options.

No, extra real memory does not effect your data, heap or stack space.  Also,
there is a hard limit of 256 MB per segment.  This means that unless you do
some programming tricks (which I don't know the specifics of) you are stuck
at this limit.
