# "data_rep" specifies the remote data replication method in
# a Disaster Tolerant cluster.
# When using xdc in the package, the value of data_rep must be set to
# "xdcmd".
# Legal values for data_rep: xdcmd.
data_rep xdcmd
# RPO_Target
# "rpo_target" is used to specify the Recovery Point Objective Target.
# This refers to the maximum time window allowed after which the raid
# system will be disabled to prevent large data loss, resulting in the
# package not being able to start. This is by default set to 0.
# Recommended value is more than the value set for "raid_monitor_interval".
# Possible values are:
# 1. -1 - To ignore the rpo_target check during startup
# 2. Any positive integer including zero.
# For example, to ignore rpo_target check, configure
# rpo_target -1
# To allow only a maximum of 10 seconds of data loss, configure
# rpo_target 10
#
# Legal values for rpo_target: (value >= -1).
rpo_target 60
# Raid Monitor Interval
# "raid_monitor_interval" is the time interval, in seconds, the raid
# monitor script will wait between checks to verify the accessibility
