DB2 Multisystem

This topic describes the fundamental concepts of DB2^® Multisystem, such as distributed relational database files, node groups, and partitioning, and provides the information necessary to create and to use database files that are partitioned across multiple iSeries™ servers. Information is provided on how to configure the systems, how to create the files, and how the files can be used in applications. This topic also describes table partitioning. Table partitioning varies from multisystem partitioning in that it is a table partitioned on a single server.
