Depending on the system you are using, define the environment of the HA monitor in the definition file sysdef. You must specify the settings individually in each host including the N number of executing nodes and the single standby node for recovery.

Set a unique name (host name of the HA monitor), address (unique value for resetting the CPU), lan (host name of LAN) according to the host environment. You must set unique values even in the N number of executing nodes and the single standby node for recovery. Also, you must set the same value for lanport (service name corresponding to the host name specified in the lan operand) even in the N number of executing nodes and the single standby node for recovery.

An example of the sysdef file is as follows. N in the sample indicates the N^th value.

 
environment name     $host_N,    #Host name of the own node
            address  $uniq_N,    #Unique value for resetting the CPU
            patrol   5,          #Time period for judging node failure
            lan      $host_N     #Host name of LAN
            lanport  $service_N  #Service name corresponding to the host name of lan operand
