How do I delay the heartbeat between the Primary and backup Servers in a redundant setup?

Solution:

The HEARTBEAT_INTERVAL keyword can be used in the license.dat file. Below is an example of how the HEARTBEAT_INTERVAL feature can be used:

SERVER host hostid1 port HEARTBEAT_INTERVAL=seconds
SERVER host1 hostid2 port
SERVER host2 hostid3 port

"For a three-server redundant configuration, indicates how long a server waits to receive a heartbeat from another server in the configuration before shutting itself down, where seconds is used in the following equation to calculate timeout:

timeout = (3 x seconds) + (seconds - 1)

If not specified, the default value for seconds is 20, equating to a timeout of 79 seconds. Valid values for seconds are 0 through 120. This parameter is optional and is placed on the first SERVER line in the license file. You must be running
v10.8 vendor daemon to use this parameter."
