XA transactions (no replies)

In running two XA transactions, how do I sync two transactions on two different machines. If I do an XA Start

on the first server, how do I get the portion of the transaction on one server and a portion on the other.

first server
XA start 'banana'



second server

XA .... What do I do here.

I am running on mysql client, no jdbc, just mysql. tables are innodb.
