SQL> /* From ORACLE DOC
DOC>For index-organized tables, Oracle uses the address of the primary key, as well as
DOC>its value, to construct logical rowids. The logical rowids are stored in the
DOC>secondary index of the table. If you move a partition of an index-organized table,
DOC>then the address portion of the rowids will change, which can hamper performance.
DOC>To ensure optimal performance, rebuild the secondary index(es) on the moved
DOC>partition to update the rowids.
DOC>
DOC><During "move">
DOC>Oracle invalidates any global indexes on heap-organized tables. You can update
DOC>these indexes during this operation using the update_global_index_clause.
DOC>Global indexes on index-organized tables are primary key based, so they do not
DOC>become unusable.
DOC>
DOC>The move_table_clause rebuilds the index-organized table's primary key index.
DOC>
DOC>ONLINE Clause
DOC>
DOC>Specify ONLINE if you want DML operations on the index-organized table to be
DOC>allowed during rebuilding of the table's primary key index.
DOC>
DOC>Restrictions on the ONLINE Clause
DOC>
DOC>    * You cannot combine this clause with any other clause in the same statement.
DOC>    * You can specify this clause only for a nonpartitioned index-organized table.
DOC>    * Parallel DML is not supported during online MOVE. If you specify ONLINE and
DOC>      then issue parallel DML statements, then Oracle returns an error.
DOC>
DOC><From ORACLE SQL reference mannual>
DOC>"online" is under move_table_clause.
DOC>There is no "online" sub-clause under alter_table_partitioing.move_table_partition clause.
