When attempting to insert a new machine definition, JIL is rejecting it with a CAUAJM_E_18972 error saying "The machine attributes "key_to_agent and encryption_type" must be the same for machines with the same agent name WA_AGENT."
This error occurs when you are attempting to define a machine with an agent name that is shared with machines that are already defined but have a different "encryption_type" or "key_to_agent" value than the machine you are inserting. All machines that share a common agent name must have matching "encryption_type" and "key_to_agent" values.
Release: ATSYHA99000-11.3.6-Workload Automation AE-High Availability Option
Make sure that all machines that share the same agent name have the same values for "encryption_type" and "key_to_agent". If it is required that machines have different values for these attributes, then the agents must be configured with unique agent names.
