Hello list, I am unable to get a value in dba_indexes(pct_direct_access) for
  a bitmap index I created on an iot.  I am using Oracle 9.2.0.1.0
enterprise
  edition on windows .
  Can someone help me by telling me what I need to do.
  I have done the following :

  --First create the iot with a mapping table.
  sql> create table countries
   ( country_id char(2) ,
   country_name varchar2 (40) ,
   currency_name varchar2(25),
   constraint country_c_id_pk primary key (country_id ) )
   organization index including country_name
   pctthreshold 20
   tablespace users
  overflow tablespace indx
   mapping table;

  Table created.

  SQL> insert into HR.countries values ( 'C', 'A', NULL )   ;
  1 row created.

  SQL> insert into HR.countries values ( 'D', 'A', NULL ) ;
  1 row created.

  SQL> insert into HR.countries values ( 'E', 'A', NULL )   ;
  1 row created.

  SQL> COMMIT ;
  Commit complete.


  --Now create a bmp index on it.
  SQL> create bitmap index myindex on countries (country_name ) ;
  Index created.

  --This command should analyze the iot and its mapping table.
  SQL> analyze table countries compute statistics;
  Table analyzed.

  --Might as well analyze the bmp index ( this does no harm right ? )
  SQL> analyze index myindex compute statistics;
  Index analyzed.

  SQL> select index_name, pct_direct_access from DBA_indexes where index
  _name = 'MYINDEX' and owner=user;

  INDEX_NAME                     PCT_DIRECT_ACCESS
  ------------------------------ -----------------
  MYINDEX

  --As you can see  I get a null value in the pct_dircect_access column.

  .....................Thanks
