A technique for managing messages stored in a messaging system may include determining whether messages designated for deletion within a current data container exceed a predetermined threshold. If such a determination is made, thereafter, a first amount of time required to delete the messages designated for deletion is calculated. A second amount of time required to copy the messages not designated for deletion in the current data container is also calculated. Thereafter, messages are selectively deleted or copied based at least in part on the calculated first and second amounts of time. In some variations, if the second amount of time exceeds the first amount of time (or exceeds the first amount of time by a predetermined threshold), then the messages designated for deletion are deleted. Otherwise, the messages not designated for deletion may be copied into a new data container and the current data container may be dropped.

Technique for managing messages

A system and method of archiving messages is disclosed. A number p random numbers are stored in a control table, the random numbers being selected from a range (M, N) where N&#x3e;M. Each random number is initially state-free in the control table. A number p archive processes are generated, each archive process configured to store one or more messages being processed by the messaging system to an archive. State-free random numbers are assigned to messages being processed by the messaging system. The messages being processed are divided by the messaging system among the p archive processes according to the assigned.

Parallel archiving for a messaging system

A persistence layer for a message exchange system of an application integration system is disclosed. The message exchange system includes a message transport layer configured to transport messages from at least one sending application to one or more receiving applications, and a business process layer configured to execute business process logic on select ones of the messages processed by the message transport layer. The persistence layer is accessible by both the message transport layer and the business process layer, and is configured to store a reference associated with each messages processed by the message transport layer. A system further includes a database accessible from the persistence layer for storing a copy of each messages corresponding to the message references stored in the persistence layer.
