Message Reconciliation During Disaster Recovery

A system for message reconciliation during disaster recovery in an asynchronous replication system, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• intercept a message at a gateway component remote from a primary data centre to which the message is being sent;
• store a copy of the message in a request message history remotely from the primary data centre;
• forward the message to the primary data centre;
• store a transaction history of the message at the primary data centre which is mirrored to a disaster recovery site with other data from the primary data centre;
• and
• in response to determining that the primary data centre has failed, compare messages in the request message history with messages in the transaction history has retrieved from the disaster recovery site.

A computer program product stored on a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• intercept a message at a gateway remote from a primary data centre to which the message is being sent;
• store a copy of the message in a request message history remotely from the primary data centre;
• forward the message to the primary data centre;
• store a transaction history message at the primary data centre which is mirrored to a disaster recovery site with other data from the primary data centre;
• and
• in response to determining that the primary data centre has failed, compare messages in the request message history with messages in the transaction history as retrieved from the disaster recovery site.
