Hi Carl,

A client I work with (a R1 research university) uses Grouper 2.1.5
with Oracle The Grouper daily report shows

memberships: 562,538
groups: 67,314
members: 147,928
folders: 6,900

Early in the deployment the Grouper loader logged one database error
(ORA-00001: unique constraint (GROUPER.STEM_NAME_IDX) violated) but we
have not seen it again after 4 months of continuous production.
Performance appears to be acceptable and we have not had to do any
special tuning work.
