Why?

I'm creating this table

create table blah
( dummy varchar2(100) )
logging
tablespace data
storage (initial 10M
next 10M)
nocache
/

select initial_extent,
next_extent,
tablespace_name,
extents
from user_segments where segment_name = 'BLAH';

INITIAL_EXTENT NEXT_EXTENT TABLESPACE_NAME EXTENTS
-------------- ----------- ------------------------------ ---------
10485760 16384 DATA 641

What happened with NEXT_EXTENT and number of EXTENTS?

I'm working with Oracle 9i on Solaris 9.2.0.1.0

Is there something different with oracle 8i using extents?

Note.
I'm using undo tablespaces.

Tx

-- i believe, becuase by default the extent managment is local ..ie..tablespace is LOCAL TABLESPACE.
-- for a DICTIONARY TABLESPACE u can getit.
-- it is same in 8i
