The table below lists the EC2 parameters. These values are set by adding them to the /etc/default/LifeKeeper configuration file. Because none of the components of the Recovery Kit for EC2 are memory resident, changes to these particular values become effective immediately after they are changed in /etc/default/LifeKeeper without requiring a LifeKeeper restart.
