<h3 align=center>Release 4.2: DB->set_cache_priority</h3>
<p>In previous releases, applications set the priority of a database's
pages in the Berkeley DB buffer cache with the DB->set_cache_priority
method. This method is no longer available. Applications wanting to
set database page priorities in the buffer cache should use the
<a href="../../api_c/memp_set_priority.html">DB_MPOOLFILE->set_priority</a> method instead. The new call takes the same
arguments and behaves identically to the old call, except that a
<a href="../../api_c/mempfile_class.html">DB_MPOOLFILE</a> buffer cache file handle is used instead of the
<a href="../../api_c/db_class.html">DB</a> database handle.</p>
