<literal>openjpa.jdbc.SQLDiag</literal>: This logging channel provides additional
information about entity actitvies such as create, find, update or delete, and eager
loading of relation or field properties. If you enable this channel, it is recommanded
that <literal>openjpa.jdbc.SQL</literal> channel is also enabled.
The additional trace can help you relate the entity activities to the execution of
SQL statements that OpenJPA issued to the datastore.
