Abstract
Methods of processing transactions in a multi-tier network of at least one database client and a plurality of database servers including a primary and a backup database server are described. One method includes the step of concurrently executing a plurality of transactions including a selected transaction on a first database server during an epoch exclusively identifying the first database server as a primary. The selected transaction is committed on the first database server in response to a commit request, if the commit request is encountered before the epoch is changed. The selected transaction is broadcast to a second database server for non-concurrent execution. The selected transaction is committed on the second database server if execution is completed and the epoch has not changed.
