Hi list,
a quick question about oracle optimizer.
a customer has database migrated from 7.3.4 to 8.1.6 on AIX. Data was
transfered via full exp/imp. After migration the performance of the new
database is very poor. I looked at the parameters and saw that no object is
analyzed. So now me question:
What does oracle optimizer do, if there are no statistics on all objects.
Optimizer level is choose.
