Some HiRDB commands are executed at each server machine using the remote shell function. For this purpose, you must set appropriate information in /etc/hosts.equiv or $HOME/.rhosts to enable mutual log-in between the server machines that constitute the HiRDB parallel server configuration.

When you create the $HOME/.cshrc file without a registration terminal, make sure that data is not output to the standard output file or the standard error file.

When you are using the system switchover facility without inheriting IP addresses, use the remote shell facility to transfer running system information to the standby system. For this purpose, you must set appropriate information in /etc/hosts.equiv or $HOME/.rhosts to enable mutual log-in between the server machine constituting the primary system and the server machine constituting the secondary system.

When you create the $HOME/.cshrc file without a registration terminal, make sure that data is not output to the standard output file or the standard error file.

Some HiRDB commands entered from a HiRDB single server configuration can be executed on a utility special unit by using the remote shell facility. For this purpose, the superuser must set appropriate information in /etc/hosts.equiv or $HOME/.rhosts to enable mutual log-in between the HiRDB single server configuration and the utility special unit.

When the $HOME/.cshrc file is created without a registration terminal, the superuser should ensure that data is not output to the standard output file or the standard error file.
