1. A method for processing complex read-only queries in parallel, said method comprising the steps of: a) Sending an end.sub.-- update command to an external operations command processor in a front end processor to cause one or more slave central processors complexes (CPCs) in a query processor complex to operate in read-only mode; b) initiating a complex read-only query on said front end processor; c) routing said complex read-only query to a master CPC in said query processor complex; d) splitting said complex read-only into two or more query elements and scheduling each of said two or more query elements for execution by one of the one or more slave CPCs, each one of said slave CPCs independently executing a database management system, each one of said CPCs comprising each of said one or more slave CPCs being capable of accessing any part of a database using a slave channel means; e) forwarding a set of results of said two or more query element executions back to said master CPC reassembling the set of results into a combined final result and forwarding the combined final result back to said front-end processor.
