Table size never affected the speed of this particular operation on any
Oracle version for us, for any heap organized table, partitioned or not. Did it
a lot of times, was never a problem.
Actually, problems appear after the modification.
BTW: Oracle was saying that data type length and precision modifiers
are check constraints in fact, data is still stored in a variable length format
(at least for varchar2 and number.)

A co-worker needs to modify a varchar2 column from 100 bytes to
200 bytes in a large table. We think that it will just modify the data
dictionary and not do a full table scan. Does anyone know for sure? Yep, I've
RTFM'd and google'd and metalink'd it. Thx.
