Pluggable tablespaces for database systems

摘要

A pluggable tablespace is enabled by logically partitioning a database into a set of tablespaces and storing all of the tablespaces disk pointers in tablespace-relative format. A pluggable set of tablespaces is unplugged by exporting the associated metadata, and making a binary copy of the tablespaces. The pluggable set of tablespaces is plugged into a target database by making the pluggable set accessible to the target database and importing the associated metadata, without patching any of the disk pointers.
