Can we rebuild the Oracle BITMAP index using REBUILD ONLINE option?

Recently development team come up with new plan for index rebuild maintenance activity using their job for index rebuild instead of DBA manually running...

What their code will do?

Create the procedure on database level - This procedure will create the dynamic index rebuild script based on BLEVEL > 2 indexes.

Note: we are frequently rebuilding the indexes which BLEVEL > 2 and avoid the fragmentation.

I have suggested to developer, while index rebuild to user parallel 4 (degree value) for performance (rebuild the indexes faster) , once they done the rebuild to reset the default degree value.

Also asked to use “REBUILD ONLINE “  option for all indexes except BITMAP INDEX. Because we can't rebuild online for BITMAP index

After they tested in non production region, “We can able to rebuild online for BITMAP index".  I have done index rebuild for BITMAP indexes several times. I used only REBUILD option for BITMAP.

I am not sure... So I have tested again.

Finally I knew, from oracle 10g onwards, we can rebuild the BITMAP index using REBUILD ONLINE.

On Oracle 11g:

 SQL> create table AM.AM_objects as select * from dba_objects;
 Table created.

 SQL> create bitmap index AM.AM_objects_idx on AM.AM_objects(object_id);
 Index created.

 SQL> alter index AM.AM_objects_idx rebuild online;
 Index altered.

 On Oracle 10g:

 SQL> create table AM.AM_objects as select * from dba_objects;
Table created.

SQL> create bitmap index AM.AM_objects_idx on AM.AM_objects(object_id);
 Index created.

SQL> alter index AM.AM_objects_idx rebuild online;
 Index altered.

 On Oracle 9i: 

 SQL> create table AM.AM_objects as select * from dba_objects;
 Table created.

SQL> create bitmap index AM.AM_objects_idx on AM.AM_objects(object_id);
 Index created.

SQL>  alter index AM.AM_objects_idx rebuild online;
alter index AM.AM_objects_idx rebuild online
