The big boys (ie Oracle, DB2) I don't worry about so much. Our open source brethren is my main concern especially since we are touting these DB's as an integral component to our unified 'stack'. | | | | So what you'd be after is something that allowed multiple one-phase resources but whenever a transaction saw more than one of them it said something like "WARNING: YOU ARE SERIOUSLY F*CKING WITH YOUR APPLICATION CONSISTENCY. BACK OFF, TAKE A VACATION AND THEN IF YOU ARE REALLY SURE YOU WANT TO DO THIS THEN CONSIDER YOURSELF WARNED." Our JCA implementation already does this: log.warn("Prepare called on a local tx. Use of local transactions on a jta transaction with more than one branch may result in inconsistent data in some cases of failure."); I thought this message had been turned off, I guess it was just clarified I think the old message was something very cryptic like: "You are not getting the behavior you expect" And this confused the shit outta people.
