heterogeneous transactions = transactions the span heterogeneous data
sources (e.g., Oracle and Sybase)
The EJB spec requires the EJB Server to provide support for distributed
transactions, but that doesn't mean that the EJB server has to support 2PC
operations across heterogeneous data sources. Only a handful of EJB servers
provide an integrated distributed transaction coordinator: Inprise AS,
OrchidSoft Vanda, NetDynamics 5.0 (I think), Component Broker (I think),
GemStone/J (I think). Most EJB servers rely on the database to coordinate
distributed database transactions -- which limits you to homogeneous
transactions (e.g., only Oracle or only Sybase).
