<p>
Configuring the Heap access method is fairly simple. Beyond the general
configuration required for any access method, you only need to
decide how large you are willing to allow the database to become.
</p>
<p>
If you provide no configuration relative to the heap size, then the
database will grow without bound. Whether this is desirable depends on
how much disk space is available to your application.
</p>
<p>
You can limit the size of the on-disk database file by using the
<a href="../api_reference/C/dbset_heapsize.html" class="olink">DB-&gt;set_heapsize()</a> method. If the size specified on this method is
reached, then further attempts to insert/update records will fail
with a <code class="literal">DB_HEAP_FULL</code> error message.
