Answer 1

I usually do the following
1) set sort area big:
-- Check the available memory on the OS with top.
-- If you go overboard on the memory allocation, sar –g will show paging
-- I usually set the sort_area_size some where between 200 and 900 meg to speed up index rebuilds
alter session set workarea_size_policy='MANUAL';
alter session set sort_area_size=900000000;
alter session set sort_area_retained_size=900000000;
2) use the following to rebuild each index so I can control the parallelism:
-- can also use online compress parallel 8
alter index "&1"."&2" rebuild parallel 8 nologging tablespace &3;
alter index "&1"."&2" noparallel;
execute dbms_stats.gather_index_stats('&1','&2',estimate_percent=>3)
3) You can also control the parallelism by setting:
parallel_min_percent=25
parallel_min_servers=10
parallel_max_servers=100
