2.10.4 Notes on communication protocols of JP1/Base
JP1/Base recognizes the host name when communicating with a host. When running on a physical host, JP1/Base recognizes, as the local host name, the host name returned by the hostname command. When running on a logical host, JP1/Base recognizes, as the local host name, the logical host name specified in the settings for the cluster system. Note, therefore, the following:
-
Use one representative host name and avoid use of several alias names.
-
JP1/Base does not operate properly if the IP address assigned to a host name cannot be resolved.
-
You must set up an environment that allows for both the conversion from a host name to an IP address and the conversion from an IP address to a host name. Setting the bi-directional conversion indicated above is necessary especially for resolving names on a DNS server (including Active Directory).
-
In an environment with multiple LAN connections where a host name resolves to multiple IP addresses, JP1/Base uses the IP address with the highest priority for the host name.
-
If JP1/Base uses the IP binding method for sending, the IP address with the highest priority for the local host name is used as the source IP address.
