Prior to Oracle9i, any table re-organizations and redefinitions forced the table to be offlined for the duration of the operation.
From Oracle9i forward, table re-organizations and redefinitions can be performed online. This note explains how to reorganize a table online.
NOTE: This note does not cover the use of row ids. As of 22.214.171.124, additional parameters were added to the DBMS_REDEFINITION
packages which allow redefinition to use a row id instead of a primary key.
This article is intended to help the database administrators to do Online table redefinition in Oracle9i and later.
