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.

[ What is claimed is:] [1.] A method for unplugging a set of tablespaces, associated with metadata and having a plurality of disk pointers, from a source database to a memory, comprising the computer-implemented steps of:storing said plurality of disk pointers in tablespace-relative format;saving said metadata into a metadata file; andmaking a binary copy of said set of tablespaces and said metadata file to said memory wherein said plurality of disk pointers with said binary copy, when plugged into a target database, is capable of being used for locating associated data items without patching said plurality of disk pointers.
