RE: Hetergenous Dataguard

Excellent point.  I assumed since one of the source databases was AIX that the 
Solaris machine would be SPARC, but I should have noted that assumption.  

As far as I'm aware, the AIX to linux restore is not possible in 10g though.

I have in fact done two such restores. Both times doing a restore on
linux from solaris.  Both are x86-64.  I have a blog post about it as
well on http://www.pythian.com.  Oracle does support this as long as
both architectures are the same and a convert is done on any
tablespaces containing UNDO segments.

If you meant Solaris SPARC, then yes, it woudn't work.
