Sybrand,
You seem to have very little expectations and trust in your current DBMS....
Of course it is nonsensical in an environment where DDL is auto commit.
It is very sensical in one where I play in DDL as a transaction..
It's not only about having active users, even queries are expected to be
in flight. And no we didn't cook this up. Real DB2 customers demand this
level of on-line schema evolution.
You simply cannot interrupt or drain a complex warehouse query just
because you need to patch a view!
Open your mind man!
Serge
