If you ever want to create or rebuild an oracle spatial index in another schema, you need to make sure that the target user has CREATE TABLE and CREATE SEQUENCE granted.
select privilege
from DBA_SYS_PRIVS
where privilege in ('CREATE TABLE', 'CREATE SEQUENCE' )
and grantee = 'TARGET_SCHEMA'
and if they don't have it
grant CREATE TABLE to target_schema;
grant CREATE SEQUENCE to target_schema;
otherwise you will get these errors, hope this helps someone :)
