TAF - DTP
I'm testing the XA tecnology against oracle rac 10GR2 (10.2.0.4 patchset) . It's seem to work very well with DTP service feature enabled. By the way now I think to enable and test the TAF on this service.
I have searched on metalink document about it, by I find only this one about compaibility of DTP/XA & TAF :

Solution for a Oracle10gR2 (10.2) Oracle Real Application Clusters
======================================================
So I think TAF is "supported" for a DTP service .
