Hi

The above is not quite true. Global temp tables *do* generate redo (albeit
indirectly) and potentially quite a bit of it. The point to make here is
that changes to GTT generate undo and this undo makes changes to undo
segments and these changes subsequently generate redo. So depending on the
type of DML (eg. deletes) and the volume of changes, you can end up
generating quite a bit of the redo.

Not as much as a non-GTT but enough to certainly invalidate the above
statement.

Cheers
