"Invalid option" while creating a tablespace
The autoextend option belongs to the datafile specification (one per datafile), not to the tablespace itself, and the uniform option is part of the extent management clause, so you've got a mixup there.

Try:

CREATE TABLESPACE ACME_DATA
DATAFILE
  '/oracle/d02/acme/ACME_DATA_01.dbf' SIZE 40M AUTOEXTEND ON NEXT 2M MAXSIZE 100M
EXTENT MANAGEMENT
  LOCAL UNIFORM SIZE 128K
SEGMENT SPACE MANAGEMENT
  AUTO;


(Note: size units are K, M, G, not KB or similar.)
