# How can one change the parameter value of O2CB_HEARTBEAT_THRESHOLD?
This parameter value could be changed by adding it to 
/etc/sysconfig/o2cb and RESTARTING the O2CB cluster. This value should 
be the SAME on ALL the nodes in the cluster.

If you have the latest o2cb init script, "/etc/init.d/o2cb configure" will
allow you to add the value too.
