It may be specific to Peoplesoft, but at two different clients I have seen
performance issues when going to 9.2.0.5. The CBO suddenly uses a lot of "merge
join cartesian " with a "buffer sort " on the inner table. That causes a lot of
problems when the estimated cardinality for the outer table is wrong.
The other thing I have seen are a lot more index skip scan accesses than
before. Again, often not appropriate.
It may be a consequence of running without cpu costing (i.e. no system
statistics in place).
Could you please post any interesting findings here.
