If you upgrade to a newer version of Oracle Business Intelligence or install a patch and work with objects in the catalog, then you might notice that certain objects are not accessed as quickly as in the previous release. This change can occur if objects were not upgraded properly. You can confirm the need to update by viewing the metrics in Fusion Middleware Control. In the Catalog folder, find a metric called “Reads Needing Upgrade” with the description “The number of objects read that required upgrading”. If the number is large, then you can resolve this issue by updating objects in the catalog using the Administration page in Presentation Services. See Oracle Fusion Middleware Upgrade Guide for Oracle Business Intelligence.
