that actually makes sense when you think about it, with one question --
was the tablespace a dictionary-managed one or an LMT?
If it was dictionary-managed, it makes perfect sense. The metadata
about the table and the extents used in the tablespace are not stored
IN that tablespace, so drop table would affect only the system
tablespace and the data dictionary.
But in an LMT, the bitmap of extent usage is stored within the
tablespace itself, so I wonder if you could actually drop a table from
a read-only lmt.
Off to experiment......
