Examples of LastResourceRecord

com.arjuna.ats.arjuna.LastResourceRecord
AbstractRecord that helps us do the last resource commit optimization. Basically this is something that is used to allow a *single* resource that is only one-phase aware to be enlisted with a transaction that is usually two-phase. The way it works is: (i) the coordinator runs its normal first (prepare) phase on all two-phase aware participants and makes a decision based solely on their responses as to whether to commit or roll back. Note, the one-phase aware resource essentially returns voteCommit during prepare, to ensure that the second phase runs even if all other resources return voteReadOnly. (ii) if the transaction is to commit then the coordinator invokes the second phase on *all* participants, starting with the one that is only one-phase aware. If it rolls back, it rolls all resources back, but the order is not important. @author Mark Little (mark@arjuna.com) @version $Id: LastResourceRecord.java 2342 2006-03-30 13:06:17Z $ @since ATS 3.2.
