Global Variables

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space to access the variable list and choose the variable to use from it.

Usage rule

This component works standalone to change the status of given
instances on Amazon EC2. You can use this component to suspend,
resume or terminate the instance(s) you have deployed Jobs
on.

This component often works alongside tCloudStart to change the status of the instances
launched by the latter component.
