Overview

This interface contains accessor methods for all query cache runtime information collected for an EJB. The cache miss counts need some explaining. A query-cache miss can occur due to one of five reasons: 1. The query result was not found in the query-cache 2. The query result has timed out 3. A bean which satisfies the query wasnot found in the entity cache 4. A query with relationship-caching turned on did not find the related-beans query result 5. A query which loads multiple EJBs could not load one or more of them To better aid tuning, there are separate counters provided for each of the last four of the above causes. The fifth counter is a total cache miss counter. This counter takes into account all five causes of a cache miss.
