Obviously, Mr. Richter knows little about XA DTP.   : Oracle7 supports XA.
 True, with XA Library - but it is only basic XA functionality. (See below)

  : Writing to our 2PC interface is easy. One command. "COMMIT".  There is a BIG difference between anyone's 2PC and 2PC with XA

Oracle XA Library (as of 7.0.13) does not support the following:

• Dynamic registration
• Asynchronous XA calls

I've enountered real world applications where both of these were essential or would be very helpful. Too bad, maybe we'll see it some day. Currently, however, Oracle is too busy trying to convince customers they don't need TP monitors. Perhaps if they'd hop on the bandwagon rather than try to be everything to everyone....

(Above statements not intended to offend Oracle XA people...we all do what  management says....)
