<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_reference/C/mempset_priority.html" class="olink">mempset_priority()</a> method instead. The new call takes the same
|
||
arguments and behaves identically to the old call, except that a
|
||
<a href="../api_reference/C/memp.html" class="olink">DB_MPOOLFILE</a> buffer cache file handle is used instead of the
|
||
<a href="../api_reference/C/db.html" class="olink">DB</a> database handle.</p>
