A method in a data processing system for propagation of filter expressions across multi-layered systems. If a selection criteria expression in a data request received by a first data processing engine from an application is incompatible with selection criteria expressions of a second data processing engine, the data request and the portion of the selection criteria expression that is compatible with selection criteria expressions of the second data processing engine is transmitted to the second data processing engine. If the second data processing engine received a message that matches the compatible portion of the selection criteria expression, the message that matches is transmitted to the first data processing engine. If the message that matches the compatible portion also matches the portion of the selection criteria expression that is incompatible with the selection criteria expressions of the second data processing engine, the message that matches is transmitted to the application.

Propagation of filter expressions across multi-layered systems

A highly reliable and readily scalable solution for managing events. In particular, an event is received and processed in a transaction. Any one of a plurality of event servers is selected to obtain event data based on the event and store the event data in an event data store. The event can be published to allow a subscribing event consumer to conduct further processing for the event data.

Method, system and program product for managing events

Under the present invention, when an event is received on a server, it is stored and then categorized. In being categorized, an event group pertaining to the event is identified. Based on the group of events, a set (e.g., one or more) of destinations to which the event should be routed can be determined. The group of events is then associated with an access control list (ACL) that contains entries identifying users (or groups of users) and their permissions to interact with events in that group. Once the association is made, the event and optionally the ACL is routed to the appropriate destinations. Based on the permissions contained in the ACL, the destinations will interact with the event accordingly.
