Thanks,

Hello again after a long time!
First of all, I was speaking about the 3PC, as described by the state automata on the
[http://ei.cs.vt.edu/~cs5204/fall99/distributedDBMS/sreenu/3pc.html]. Notice the P1 (coordinator), and the Pi (cohort) states. For one the timeout leads to abort and for the other it leads to commit. Isn't that wrong?
I didn't study your link, but this confuses me: "By the time any cohort can send an ACK, it has already been decided by the coordinator whether the transaction is committing or aborting" - if the coordinator has decided, then what is the need for further ACKs or NACKs?
I believe the timeouts necessarily introduce a degree of uncertainty whether both will actually abort or commit.
