Currently Tamino does not support two-phase commit. I have heard of similar requirements from application developers using EJB.
I have heard only rumours so far that eventually Tamino will be 2PC compliant but I have heard of no timescales as yet, so it seems it is something R&D are / will be working on. :rolleyes:
I wonder if anyone else can confirm or deny this?
