I have this dev db duplicated from prod and many of the materialized view refreshes that are scheduled with dbms_jobs fail no matter when I schedule them.  These refreshes run in about one second and seem to run every time if I run them in sqlplus using sys.dbms_sys_sql.parse_as_user.  I don't believe this is a undo config issue because the jobs seem to run anytime of day in sqlplus and they run fine in prod.  This seems rather like a bug.

I started with Note:1950577.1#FIX  ORA-1555 Reported with Query Duration = 0 , or a Few Seconds

Howdy, Stranger!
