This appendix describes how to configure IPv6.
Use the following steps to configure JEUS in IPv6 environment.
Modify the jeus, jeus-quickstart, startexampleserver, jeus.properties, startderby, and stopderby scripts.
Add environment variables for the embedded WebtoB.
Verify operation.
The loopback address must be set to "::1" in the 'hosts' file of the server.
The 'hosts' file is located in the following paths, depending on the OS.
Windows
C:/WINDOWS/system32/drivers/etc
UNIX series
/etc/hosts
The following is a sample 'hosts' file.
[Example B.1] <<hosts>>
[jeusqa@ipv6linux /home/jeusqa]$ cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. #127.0.0.1 localhost #::1 localhost6.localdomain6 localhost6 ::1 localhost
This section describes the environment configurations for IPv6.
IPv6 environment configurations are different for each file.
File Name : jeus, jeus-quickstart, and startexampleserver
Existing environment variable
-Djava.net.preferIPv4Stack=true /
Updated environment variables
-Djava.net.preferIPv6Addresses=true / -Djava.net.preferIPv4Stack=false /
File Name : jeus.properties
Existing environment variable
TOOL_OPTION="-Djeus.tm.not_use=true -Djava.net.preferIPv4Stack=true"
Updated environment variable
TOOL_OPTION="-Djeus.tm.not_use=true -Djava.net.preferIPv6Addresses=true -Djava.net.preferIPv4Stack=false"
File Name :: startderby and stopderby
Existing environment variable
-Dderby.system.home="${JEUS_HOME}/derby/databases" /
Updated environment variables
-Dderby.system.home="${JEUS_HOME}/derby/databases" /
-Djava.net.preferIPv6Addresses=true /
-Djava.net.preferIPv4Stack=false /
