You try a few experiments. For example,
orclz> create table iot (c1 number,c2 date,primary key (c1,c2)) organization index compress advanced low;
create table iot (c1 number,c2 date,primary key (c1,c2)) organization index compress advanced low
*
ERROR at line 1:
ORA-00922: missing or invalid option
orclz> create table iot (c1 number,c2 date,primary key (c1,c2)) organization index compress;
Table created.
orclz>

Thanks, John.
How about existing tables? I've tried the following for Advanced Row Compression:
ALTER TABLE MY_IOT_TABLE MOVE ROW STORE COMPRESS ADVANCED;
ALTER TABLE MY_IOT_TABLE MOVE ROW STORE COMPRESS ADVANCED
*
ERROR at line 1:
ORA-02158: invalid CREATE INDEX option
Also, is "...organization index compress" the same as Advanced Row Compression?
Regards,
Zaf

No.
If you look in the Administrator's Guide chapter 21, you will find a full description. Including this,
Note:
Advanced index compression is not supported for bitmap indexes or index-organized tables.
Advanced index compression cannot be specified on a single column unique index.
