I was looking at v$segment_statistics and there isn't any data. Then I remembered that Oracle support had me set _object_statistics=FALSE several months ago to take care of an issue we were having. So much for getting cache hit ratios on the tables. Think I might remove the parameter on a test database just to see if one of the numerous patches we put on fixed the problem and I don't really need this setting. Fortunately, I have a sandbox test database. -- Sandy Transzap, Inc.
