Overview of Distributed Queries

The IBM Informix database servers allows you to query more than one database across multiple database servers. This type of query is called a distributed query. The database servers can reside on a single host computer, on the same network, or on a gateway.

Note:
IBM Informix Extended Parallel Server, Version 8.40 supports participant functionality only. Distributed queries cannot originate from this version. IBM Informix Extended Parallel Server, Version 8.50 supports both participant and coordinator functionality. Restrictions apply.
