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> <table width="100%"><tr><td><br></td><td align=right><a href="../upgrade.4.2/del.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../upgrade.4.2/verify.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
