A METHOD OF LOGGING TRANSACTIONS AND A METHOD OF REVERSING A TRANSACTION

摘要

A method is disclosed of logging transactions including the steps of storing log records for a plurality of transactions in one or more log files and linking each log record of each individual transaction of the plurality of transactions to any preceding log record of the same transaction so that all log records of each individual transaction are linked. In one embodiment, the method includes the step of maintaining a control record for at least each current transaction that specifies the most recent log record for the transaction to thereby provide a starting point for reserving the transaction if the transaction needs to be reserved.
