from documentation: http://docs.oracle.com/cd/B28359_01/server.111/b28286/clauses004.htm#i998826
If you do not specify SIZE, then the database creates a 100M file with AUTOEXTEND enabled. When autoextension is required, the database extends the file by its original size or 100MB, whichever is smaller. You can override this default behavior by specifying the NEXT clause.http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_7003.htm:
You must specify the DATAFILE or TEMPFILE clause unless you have enabled Oracle-managed files by setting a value for the DB_CREATE_FILE_DEST initialization parameter. For Automatic Storage Management disk group files, the parameter must be set to a multiple file creation form of Automatic Storage Management filenames. If this parameter is set, then the database creates a system-named 100 MB file in the default file destination specified in the parameter. The file has AUTOEXTEND enabled and an unlimited maximum size.
