DB2® Multisystem overview
The primary and only benefit of using Db2® Multisystem is to enable the option of using an SQL partitioned table to achieve a much larger SQL table.
In previous releases, Db2 Multisystem could also be used to distribute portions of an SQL partitioned table across multiple IBM i systems. This use of Db2 Multisystem is no longer recommended. Instead, clients are encouraged to evaluate the many feature benefits of Db2 Mirror.
