Doug,
This is a case where something slipped by in one
release, but was caught in a later release (shades of
Personal Oracle 8.0.3 which had complete EE
functionality by mistake). 8i doesn't support
autonomous transactions within distributed
transactions, but it wasn't officially prevented with
the ORA-164 error until 8.1.6+.
Supposedly this functionality will be available in 9i,
but not necessarily the first release.
HTH,
