What happens when ?

Hello, Suppose I have created a database "abc" on dbspace "def". Later I created several dbspaces and created tables/indexes on those. Now, somebody by mistake dropped dbspace "def", but all the other dbspaces are fine. So, I can not open "abc". At this situation, if I want to use "abc", What should be done ? Is any/all of the possibilities possible ? 1. Restore from tape by "ontape -r -D abc" . 2. Recreate the "abc" database on newly created dbspace "def". Thanks. Sincerely, Anjan
