WebSphere® Application Server includes a new property to use for message persistence.
WebSphere Application Server includes a flag to persist the re-delivery condition for error messages. Restarting the application server does not reset this flag, therefore error messages will not be reprocessed upon a server restart.
Enable the Keep count of failed deliveries per message option from the WebSphere Application Server Admin Console for all integration bus destinations. Log in to the WebSphere Application Server Admin Console, and navigate to to set this option.
