We have Oracle Grid control 10.2.0.2 on solaris 10. Some of the custom written reports are eating up quite a bit of CPU cycles (tables are not large). The issue seems to be incorrect query plan. Do we need to anything special on gathering schema/object statistics? I am thinking of gathering statistics once a week for the entire schema. Any suggestions?
