|
||
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 <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> 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.
