SQL & PL/SQL

I created a table using:

create table employee (eid number(10) primary key, ename varchar2(15), esex char(1));
create index e_esex_id on employee(esex);

It has created two indexes on E_DATA since the default tablespace for that user is E_DATA. But, I want to move those indexes to different tablespace called E_INDEX. I used the following scripts:

ALTER INDEX SYS_C004910 REBUILD PARAMETERS('TABLESPACE=E_INDEX');
ALTER INDEX ESEX_ID_IDX REBUILD PARAMETERS('TABLESPACE=E_INDEX');

But, it is givinng the following error:

ORA-29870: specified options are only valid for altering a domain index

Any help ?

Thanks.

PS:I dont want to drop the table and recreate it again.
