ABSTRACT:
Messages are redistributed in a clustered messaging environment including messaging servers and consuming applications. Each messaging server has a queue partition operable to contain messages. Each consuming application can connect to a messaging server in to consume one or more messages from a queue partition local to that messaging server. A message on a holding queue partition local to a messaging server without at least one consumer interested in consuming that message is said to be marooned. A marooned message is redistributed from the holding queue partition to a messaging server that does have at least one consumer interested in consuming the message. The redistribution involves identifying a group of servers, each of which has one or more consumers interesting in consuming the message, selecting a server from the group and forwarding the message to the selected server.
