4.3.2 Defining jp1hosts information

JP1/Base can hold its own hosts information, which enables resolution of IP addresses independently of the OS. By registering this dedicated hosts information (jp1hosts information) with the common definition information, the main part of JP1/Base can communicate with IP addresses that do not correspond to physical or logical host names on the destination host. For example, if your OS cannot resolve one host name into multiple IP addresses, you can define jp1hosts information to enable JP1/Base to solve it. The jp1hosts information does not exist at the installation of JP1/Base. You need to register it with the common definition information when required. For information about which functionality of JP1/Base support the jp1hosts information, see H. Handling Changes in Communication Settings.
Note

When you define jp1hosts information, the definitions in the hosts file and DNS are not referenced for the host names and IP addresses defined in the jp1hosts information.
Example:

jp1hosts information:
  hostA 100.0.0.10, 200.0.0.10
hosts file:
  100.0.0.10 hostA hostB
  200.0.0.10 hostC
In these definitions, the hosts file is not referenced for hostA, 100.0.0.10, and 200.0.0.10.
The jp1hosts information must be registered with the common definition information when:

using a host connected to multiple networks in a cluster system, or

communication cannot be established with the IP address used in the connection with the destination host.
 
To register jp1hosts information with the common definition information:
Edit the jp1hosts definition file.
A jp1hosts definition file is provided by default. It is stored as the jp1hosts file in installation-folder\conf\ for Windows or /etc/opt/jp1base/conf/ for UNIX. This default jp1hosts definition file cannot be used without editing it. When you use the default jp1hosts definition file, you must first edit it according to the use in JP1/Base. When you create your own jp1hosts definition file, store it in the same folder as the default jp1hosts file is stored. For details on the format of the jp1hosts definition file, see jp1hosts definition file in 14. Definition Files.
Execute the jbshostsimport command in the following format to register the jp1hosts definition file with the common definition information.
Execute the command as follows:
jbshostsimport {-o|-r} jp1hosts-definition-file-name [-h logical-host-name]
Use the jbshostsexport command to check the jp1hosts information registered with the common definition information. For details on these commands, see 13. Commands.
