(Chris Eaton) The concept of a tablespace in DB2 for LUW is pretty much identical to that of DB2 for z/OS. That is, a tablespace is a storage management concept and is an object that you put tables in. So tables live in tablespaces and a tablespace is an object that has physical storage associated w
