It's very important (unforunately) that you get the syntax correct, with the keys in the right order. The syntax diagram for the CREATE TABLESPACE
statement is available here.
You've put the PAGESIZE
clause after the MANAGED BY ...
which is incorrect. It should be before:
CREATE TABLESPACE TS01
PAGESIZE 16K
MANAGED BY DATABASE
USING (FILE '/dbdata/UMPSYS01.dms' 100M)
BUFFERPOOL BPOOL
