6.11.2 Communication settings when using JP1/Base in an IPv6 environment
The following describes how to change the communication settings when adding agent host 3 and agent host 4 to the system configuration shown in Figure 6-9.
The communication settings when communicating using IPv6 addresses in an IPv6 environment differ depending on whether you use the ANY binding method or the IP binding method.
- Organization of this subsection
(1) Changes required for ANY binding method
(a) Set the ANY binding addresses
When you specify the ANY binding addresses, choose one of the files to bind IP addresses to the servers.
-
IPv6 addresses (anybind_ipv6.conf)
-
IPv4 and IPv6 addresses (anybind_all.conf)
■ Examples
- Settings required on the manager host:
-
-
Execute the jbssetcnf command with the anybind_all.conf file specified.
In Windows:
jbssetcnf installation-folder\conf\anybind_all.conf
In Linux:
jbssetcnf /etc/opt/jp1base/conf/anybind_all.conf
-
- Settings required on agent host 3 and agent host 4:
-
-
Execute the jbssetcnf command with the anybind_ipv6.conf file specified.
In Windows:
jbssetcnf installation-folder\conf\anybind_ipv6.conf
In Linux:
jbssetcnf /etc/opt/jp1base/conf/anybind_ipv6.conf
-
(b) Set jp1hosts2 information
In the jp1host2 information for each host, set the IPv6 addresses of any destination hosts that use an IPv6 address. Also set the IPv6 address of the local host in the jp1host2 information of each IPv6 host.
■ Examples
- Settings required on the manager host:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Agent3 2001:db8::28
Agent4 2001:db8::32
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
- Settings required on agent host 3:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Manager 2001:db8::1e
Agent3 2001:db8::28
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
- Settings required on agent host 4:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Manager 2001:db8::1e
Agent4 2001:db8::32
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
(2) Changes required for IP binding method
(a) Set jp1hosts2 information
In the jp1host2 information for each host, set the IPv6 addresses of any destination hosts to communicate with using IPv6 addresses, and the IPv6 address of the local host.
■ Examples
- Settings required on the manager host:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Manager 10.0.0.30 2001:db8::1e
Agent3 2001:db8::28
Agent4 2001:db8::32
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
- Settings required on agent host 3:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Manager 2001:db8::1e
Agent3 2001:db8::28
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
- Settings required on agent host 4:
-
-
Edit the jp1hosts2 definition file.
Edit the file as follows:
Manager 2001:db8::1e
Agent4 2001:db8::32
-
Execute the jbshosts2import command.
jbshosts2import {-o|-r} [jp1hosts2-definition-file-name]
-
(3) Set jp1hosts2 information and the +DefaultResolve parameter
The +DefaultResolve parameter in the jp1hosts2 information specifies how the system resolves host names that are not defined in the jp1hosts2 information. If you want JP1/Base to always use the hosts and DNS settings of the operating system to resolve IPv6 addresses, set 1 (resolve IPv4 and IPv6 addresses) as the value of the +DefaultResolve parameter.
However, when using JP1/Base in a network environment that contains IPv4 hosts and IPv6 hosts, we recommend that you define jp1hosts2 information to make it clear which IP addresses are IPv6 addresses.
The default value of the +DefaultResolve parameter is 0 (resolve IPv4 addresses only). For this reason, you do not need to set the +DefaultResolve parameter if you specify the IP addresses of IPv6 hosts in the jp1hosts2 information.
