Moving Tablespaces in Oracle 8iby Oscar Bonilla
imp, these tools only work when the import is done on the same tablespace from where the export was done. Sometimes what you want to do is move the data from one tablespace to another. This document describes a dirty hack to do that.
Say you have a tablespace call "PRODUCTION" which you need to move to a new tablespace called "DEVELOPMENT". These are the steps to move all the data from "PRODUCTION" to "DEVELOPMENT".

$ exp production/production file=production.dmp owner=production consistent=Y direct=YThis will create a file called
production.dmpthat contains a dump of your tablespace.
.dmpfile with xemacs (or optionally emacs).
$ split -b100m production.dmpThis will create files called "aa", "ab", "ac", etc. each 100MB in size.

This works because whenever you specify an owner and do not specify which tables to export, everything that has been created by that owner is exported.
