Automated database recovery

Transaction Server detects FTM database connection or JMS (IBM® MQ) connection failures and issues a ConnectivityRestored event when the database or IBM MQ recovers. Distribution registers an event handler in the Transaction Server scheduler to be notified when the event occurs.

To use the event, Distribution detects when the database goes down and acts to save the JMS messages it received on the related backout queue that is associated with each message.

When the ConnectivityRestored event is received, these backout messages are automatically posted back to the primary request queue. This action allows Distribution to resume processing the artifacts that are associated with each message and complete the work that is related to the message.
