create a new Oracle 10g database instance

Hi,

I am trying to create a new Oracle 10g database instance. It failed with "ERROR at line 1: ORA-25146: EXTENT MANAGEMENT option already specified". Below is part of the script. I don't know what could be wrong. Thanks alot.

create database
datafile
'/u01/oradata/def10g/system01.dbf'
size 100M
reuse
autoextend on
extent management local
sysaux
datafile '/u01/oradata/def10g/sysaux01.dbf'
size 100M
reuse
autoextend on
extent management local
segment space management auto
undo tablespace undo_ts
datafile '/space/oracle/admin/def10g/data/undo.dbf'
size 100M
reuse
autoextend on
extent management local
default temporary tablespace temp_df tempfile '/space/oracle/admin/def10g/data/tempdf.dbf'
size 100M
reuse
autoextend on
extent management local uniform size 20M;

You could try using dbca to create the database (and/or scripts). :rolleyes:

Kindly comment any one statement in your script
extent management local
extent management local uniform size 20M;
