I did the following in Oracle RDBMS 9i:

SQL> alter index xsc_uk rebuild tablespace ax_le_small storage (initial 128K 2 next 128K);
SQL> select initial_extent,next_extent,index_name from dba_indexes 2 where index_name like 'XSC%';

         65536      131072 XSC_CLNT_FK_I
         65536      131072 XSC_PK
        131072      131072 XSC_UK
____________________________________________________________________________

As I wish to use uniform extent sizing and I was given an import that does have that. I am a little concerned about the initial extent changing - what if there is data in the index? - how it could possibly deallocate space if you wish to have a smaller extent size. It was very quick. Did I really end up with new extents for XSC_UK each 128K????
