• If you own the master table, you can create an associated materialized view log
  if you have the CREATE TABLE privilege (included in the RESOURCE role)

• If you are creating a materialized view log for a table in another user's schema,
  you must have the CREATE ANY TABLE and COMMENT ANY TABLE privileges (not included
  in the RESOURCE role), as well as either the SELECT privilege for the master

in the tablespace intended to hold the materialized view log or must have the
UNLIMITED TABLESPACE system privilege.
