The MQ Appliance messaging server must provide a clustering capability.
An XCCDF Rule
Description
This requirement is dependent upon system criticality and confidentiality requirements. If the system categorization and confidentiality levels do not specify redundancy requirements, this requirement is NA. Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. When application failure is encountered, preserving application state facilitates application restart and return to the operational mode of the organization with less disruption of mission/business processes. Clustering of multiple messaging servers is a common approach to providing fail-safe application availability when system MAC and confidentiality levels require redundancy.
