6.8 An example of communication settings when JP1/Base is used in a cluster system (in an environment of distinct networks)

This section describes the communication settings in an environment of distinct networks when a host connected to multiple networks is used in a cluster system, based on the system configuration example shown in the following figure.

Figure 6‒7: A system configuration example when JP1/Base is used in a cluster system (in an environment of distinct networks)

This configuration assumes that only host10 connects to the physical host hostX and a logical host hostL with the IP addresses 20.0.0.11 (for the physical host) and 20.0.0.15 (for the logical host), both of which cannot be resolved against these host names. The other hosts are assumed to connect to hostX and hostL with the IP addresses 10.0.0.11 (for the physical host) and 10.0.0.15 (for the logical host), both of which can be resolved.

The table below indicates if the communication settings of each host must be changed or not in this configuration.

Host name	Communication settings of the main part of JP1/Base		Communication settings of event services (edit of conf)
	jp1hosts information	Communication protocol settings
host10	Required	Not required	Required
hostX (physical host)	Required	Required	Required
hostL (logical host)	Required	Required	Required
hostA	Not required	Not required	Not required
hostB	Not required	Not required	Not required
