Now that it seems to be working, I've ran into one small issue. Turning on Parallel=true will cause SQL Loader to not rebuild indexes (hence the skip_index_maintenance=true option to get this to work).

Does anybody have a good method / script for indentifying all indexes for a particular schema and then rebuilding indexes?

The only thing I can think of is spooling off some command like:

select 'alter index ' || index_name || ' rebuild; ' from user_indexes where table_name='MYTABLE';

That will create my sql list.. but it also spools off the select / spool off commands.
