NEXT and UNIFORM SIZE - Tablespace creation

Hi,


We are trying to understand the difference between "NEXT" and "UNIFORM SIZE" using the following example

create tablespace TEST datafile '/u02/oracle/oradata/orcl/test01.dbf' size 10M autoextend on NEXT 1M maxsize 2048M
extent management local
UNIFORM SIZE 256K
segment space management local


So are we correct in assuming that then the tablespace reaches 10MB, it will EXTEND the datafile by 1M (at O/S level) and whenever any object residing in that tablespace needs to expand, it will be allocated a 256K size extent all the time?


What will happen if we dont include the "NEXT" clause in the datafile? Would it default to 64K? and if yes,since 64K is LESS then the extent size (256K) wouldn't there be issues?

Howdy, Stranger!
