<p>
Sets the maximum size that the <code class="literal">set_cachesize</code>
parameter is allowed to set. The specified size is rounded to the
nearest multiple of the cache region size, which is the
initial cache size divided by the number of regions specified
to the <code class="literal">set_cachesize</code> parameter. If no value
is specified, it defaults to the initial cache size.
</p>
<p>
The syntax of this parameter in the
<code class="literal">DB_CONFIG</code> file is a single line with
the string <code class="literal">set_cache_max</code>, one or more
whitespace characters, and the maximum cache size in bytes,
specified in two parts: the gigabytes of cache and the
additional bytes of cache. For example:
</p>
<pre class="programlisting">set_cache_max 2 524288000</pre>
<p>
Sets the maximum cache size to 2.5GB.
</p>
<p>
This parameter can be changed with a simple restart of your
application; you do not need to re-create your environment for it
to be changed.
</p>
