Abstract: A method and associated structures for dynamically reformatting messages in a distributed computing environment based upon message content as represented by a description of the input message format and the output message format. An input message received by the formatter of the present invention is decomposed into a canonical format stored by the formatter for further use in a rapidly searchable data structure (FGA). The input message data is decomposed in accordance with an input message format description which describes the content of the input message in terms of atomic data types and structures. An output message is then generated in response to a user request and in accordance with a user provided output message format description. The output message format description describes the content of the output format in terms of atomic data types and attributes as well as functional operations performed to derive the output field value.

Abstract: Methods and associated structure providing a balanced queue communication system for the exchange of messages between an originating node and a receiving node in a distributed computing environment. A balanced queue comprises a pair of wraparound (circular) queues, one each associated with the originating node and the receiving node. A message is queued by the originating node in the queue associated therewith. Background processing within the originating node retrieves message queued therein and transmits the messages to the intended receiving node. The position in the originating node's circular queue is pre-pended to the message and transmitted therewith. The receiving node places the received message in its circular queue in the position specified by the pre-pended location with each message. Background daemon and application processing within the receiving node then retrieves the queued messages for application specific processing.

Abstract: Methods and associated structures for rapidly processing messages in a distributed computing application. Rules are stored in structures defined by the present invention and methods associated therewith rapidly process the boolean predicates of the rules to determine what actions need be taken in the distributed computing environment in response to receipt of a message published by a publishing application in the distributed computing environment. Rules argument tables store rule argument entries which each represent a single boolean predicate test clause which compare a column (field) of a published message with either a fixed value or with another column of a published message. All rule argument predicate clauses which are AND'ed to form a rule are related in the rules argument tables by a common rule.sub.-- id column value. An operations table stores entries each of which describes groups of attributes of rules stored in the rules argument tables.
