RE: Overhead of over sized datafiles

I usually try to leave 25 - 50% of the SYSTEM tablespace empty, I read about that somewhere.

That was before Oracle introduced locally managed tablespaces, maybe it's not a valid target anymore.

Probably I am just paranoid, though.

A fellow DBA working with me resized the System tablespace to double its size i.e. from 500MB to 1GB: I dont like the practise of just arbitrarily doubling a datafile size and it sitting empty for years, but apart from extra backup time , would this large oversized datafile upset the database engine in any way, or be inefficient at a database or o/s level: I suspect certain areas but to busy right now RTFM. p.s. 8.1.6 / solaris 2.8
