Abstract
A mechanism is provided for message reconciliation during disaster recovery in an asynchronous replication system. A message is intercepted at a gateway remote from a primary data center to which the message is being sent. A copy of the message request is stored in a request message history remotely from the primary data center. The message is forwarded to the primary data center. A transaction history of the message request is stored at the primary data center which is mirrored to a disaster recovery site with other data from the primary data center. In response to determining that the primary data center has failed, messages in the request message history are compared with messages in the transaction history as retrieved from the disaster recovery site.
