may refer to a transaction that was previously associated with the
current thread or with a different thread in the same execution
environment.

The handletrans argument must be
obtained from the SuspendTransaction function.
Using any other value as the argument to ResumeTransaction may have
unpredictable results.
ResumeTransaction can be called by a client
or a component that is marked as OTS style. must be using the two-phase
commit transaction coordinator (OTS/XA).
