The memory pool interfaces for the Berkeley DB database
environment are methods of the <A HREF="../../../com/sleepycat/db/DbEnv.html" title="class in com.sleepycat.db"><CODE>DbEnv</CODE></A> handle. The <A HREF="../../../com/sleepycat/db/DbEnv.html" title="class in com.sleepycat.db"><CODE>DbEnv</CODE></A> memory
pool methods and the DbMpoolFile class provide general-purpose,
page-oriented buffer management of files. Although designed to
work with the other <A HREF="../../../com/sleepycat/db/Db.html" title="class in com.sleepycat.db"><CODE>Db</CODE></A> classes, they
are also useful for more general purposes. The memory pools are
referred to in this document as simply <i>pools</i> .</p> <p>
In the Berkeley DB Java API, the DbMpoolFile class provides a very
limited set of operations. It is only intended to modify settings
for a <A HREF="../../../com/sleepycat/db/Db.html" title="class in com.sleepycat.db"><CODE>Db</CODE></A> object using the <A HREF="../../../com/sleepycat/db/Db.html#get_mpf()"><CODE>Db.get_mpf</CODE></A> method.</p>
