Re: Have you had any issues with 9.2.0.5

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.
