It´s a simple hint, but for me is very useful for migrations, mainly in aplications migrations.

To show owners (users):
find . -printf '%u\n' | sort -t: -u

To show group owners:
find . -printf '%g\n' | sort -t: -u

SQL> begin 2 for i in 1..1000 3 loop 4 insert into teste values(i, 56); 5 end loop; 6 end; 7 / PL/SQL procedure successfully completed. SQL> create index idx_teste on teste(a,b); Index created. SQL> analyze table teste compute statistics; Table analyzed. SQL> explain plan for select /*+ index_ss(teste idx_teste) */ * from teste where b=56; Explained.
