The AW_TABLESPACE function returns the name of the tablespace in which a particular analytic workspace is stored.
Note:
You cannot execute this function from within the OLAP Worksheet. You must execute if in a SQL tool such as SQL*Plus.
AW_TABLESPACE ( 
          schema        IN VARCHAR2,
          awname        IN VARCHAR2)
     RETURN VARCHAR2;
The following example shows the tablespace in which the GLOBAL analytic workspace is stored.
SET serveroutput ON
EXECUTE dbms_output.put_line('Sales History is stored in tablespace ' || 
     dbms_aw.aw_tablespace('sh_aw', 'sales_history'));
This command generates the following statement:
Sales History is stored in tablespace SH_AW
