<h1>Change Log</h1>
<h2>Next Version (unreleased)</h2>
<ul><li>File systems with a maximum file size (for example FAT) are now supported using
<ul><li>Updatable result sets: the key columns can now be updated.
</li><li>The H2DatabaseProvider for ActiveObjects is now included in the tools section.
</li><li>The H2Platform for Oracle Toplink Essential has been improved a bit.
</li><li>The Windows service to start H2 didn't work in version 1.1.
</li><li>File systems with a maximum file size (for example FAT) are now supported using
the file prefix 'split:'. In this case the files are split in parts of 1 GB.
Example URL: jdbc:h2:split:~/db/test. If you want to split into parts of 1 MB, use
jdbc:h2:split:20:~/db/test (the part size is 1 &lt;&lt; x, the default is 30 meaning 1 GB).

Only if you want other computers to access the database on this computer, you need allow remote connections

</p><p>
</p>
<p>
It has been reported that when using Kaspersky 7.0 with firewall, the H2 Console is very slow when
connecting over the IP address. A workaround is to connect using localhost, however this only works
on the local machine.
</p>
<p>
A small firewall is already built into the server: other computers may not connect to the server by default.
To change this, go to 'Preferences' and select 'Allow connections from other computers'.

<h2>Using Spring</h2>
<p>
Use the following configuration to start and stop the H2 TCP Server using the Spring Framework:
</p>
<pre>
&lt;bean id="org.h2.tools.Server"
class="org.h2.tools.Server"
factory-method="createTcpServer"
init-method="start"
destroy-method="stop"&gt;

&lt;/bean&gt;

<p>
The "destroy-method" will help prevent exceptions on hot-redeployment or when restarting server.
