RECOVERING FROM AN ORIGINATION NODE FAILURE DURING AN ASYNCHRONOUS REPLICATION

摘要

Methods and systems for recovering from an origination node failure during an asynchronous replication are provided. A system includes an origination node in a source array from which transaction are being replicated. The system includes a number of mirror nodes each logging a portion of the transactions from the origination node. A link is included between each of the mirror nodes and a node in a destination array. A detector identifies a link failure and determines a reason for the link failure, and a failure handler determines actions needed to communicate transactions to a target node.
