Server Configuration for IPv6 Support

This manual is in pilot operation.

By default, fusion_place does not support communication over IPv6. To enable IPv6 support, you must specify this in the Tomcat configuration file on the server side. This section explains the configuration item and how to specify it.

Adding Configuration to the Tomcat Configuration File on the Server

Modify the Tomcat configuration file, server.xml, as needed. For the location of server.xml, please refer to "Location for Recording Installation Information".

The content of server.xml is in XML format. By adding an Environment element (environment variable) under the Context element (specifically, those with path="/fusionplace"), you can enable communication over IPv6. Below is an example configuration:

<Context docBase="fusionplace.war" path="/fusionplace">
  <Environment name="fusionplace/dbms" value="H2" type="java.lang.String"/>
  <Environment name="fusionplace/pivot_time_out" value="60000" type="java.lang.Integer"/>

  <!-- Configuration item for IPv6 support starts here -->
  <Environment name="fusionplace/prefer_ipv4_stack" type="java.lang.Boolean" value="false" />
  <!-- Configuration item for IPv6 support ends here -->

  ・・・

</Context>

As shown above, each Environment element has three attributes: name, type, and value. Set fixed values for name and type as listed in the table below, and specify the applicable value. Multiple Environment elements can be included in any order.

name
(Environment Variable Name)		 type
(Environment Variable Type)		 value
(Environment Variable Value)

fusionplace/prefer_ipv4_stack

java.lang.Boolean

Specify "false" to enable IPv6 support. If IPv6 support is not required, specify "true" or omit this element.
