Re: default STORAGE clause when creating tables?

You don't have default storage clauses for tables in Oracle. When creating tablespaces you specify initial / next extent sizes and min/max extent numbers for objects created within the datafile(s) of that tablespace - regardless if that object is a table or index.

To alter that, e.g.:

ALTER TABLESPACE tablespace_name MINIMUM EXTENT 128K; The new values serve as default values only for subsequently allocated segments (or subsequently created objects).
