6.3.2 Changing the JP1/Base communication protocol
You can change the communication protocol used by JP1/Base by applying the contents of communication protocol settings files to the common definition information.
You can specify the ANY binding method or IP binding method as the JP1/Base communication protocol.
- Organization of this subsection
(1) Procedure for changing the JP1/Base communication protocol
To apply the contents of a communication protocol settings file to the common definition information, execute the jbssetcnf command as follows:
jbssetcnf communication-protocol-settings-file
For details on the jbssetcnf command, see jbssetcnf in 15. Commands.
(2) Communication protocol settings files
There are seven kinds of communication protocol settings file, each with a specific purpose.
- File location:
-
In Windows: installation-folder\conf\
In UNIX: /etc/opt/jp1base/conf/
Table 6‒1: Communication protocol settings files Communication protocol settings file
Purpose
physical_ipany.conf
This file sets the IP binding method for receiving and the ANY binding method for sending.
It is mainly used to change the communication protocol for physical hosts that communicate over multiple LANs in a cluster system.
logical_ipany.conf
This file sets the IP binding method for receiving and the ANY binding method for sending.
It is mainly used to change the communication protocol for logical hosts that communicate over multiple LANs in a cluster system.
You will need to edit this file.
physical_recovery_0651.conf
This file causes the communication protocol registered in the common definition information to revert back to the communication protocol used in version 06-51 or earlier.
It is mainly used to change the communication protocol set for physical hosts back to the earlier communication protocol.
The communication protocol used in version 06-51 or earlier does not support the IP binding method in an environment with multiple LAN connections.
logical_recovery_0651.conf
This file causes the communication protocol registered in the common definition information to revert back to the communication protocol used in version 06-51 or earlier.
It is mainly used to change the communication protocol set for logical hosts back to the earlier communication protocol.
You will need to edit this file.
The communication protocol used in version 06-51 or earlier does not support the IP binding method in an environment with multiple LAN connections.
physical_anyany.conf
This file sets the ANY binding method for both sending and receiving.
It is mainly used to return hosts that were operating in a cluster system to use only as physical hosts.
Using this file changes the communication protocol of the physical hosts to the ANY binding method. Having done so, you can no longer use logical hosts on the same host.
physical_ipip.conf
This file sets the IP binding method for both sending and receiving.
It is mainly used with physical hosts to explicitly specify the sending IP address when going through a firewall, or to force a host to use a specific LAN.
If you apply this setting to a host connected to multiple networks, the host will only be able to use one network.
logical_ipip.conf
This file sets the IP binding method for both sending and receiving.
It is mainly used with logical hosts to explicitly specify the sending IP address when going through a firewall, or to force a host to use a specific LAN.
You will need to edit this file.
If you apply this setting to a host connected to multiple networks, the host will only be able to use one network.
For details about which JP1/Base features are compatible with the settings in each communication protocol settings file, see H.9 Functionality supported in communication settings.
For details on the parameters defined in the communication protocol settings file, see H.10 Parameters defined in the communication protocol settings file.
(3) Example of setting the JP1/Base communication protocol
To apply the contents of a communication protocol settings file to a physical host on a host connected to multiple networks, execute the jbssetcnf command as follows:
jbssetcnf physical_ipany.conf
To apply the contents of a communication protocol settings file to a logical host on a host connected to multiple networks, first open the logical_ipany.conf file in an editor. In logical-host-name\JP1BASE, enter the logical host name you specified when setting up the cluster system, and then execute the jbssetcnf command as follows:
jbssetcnf logical_ipany.conf
