The MQ Appliance messaging server must provide a clustering capability.
An XCCDF Rule
Description
<VulnDiscussion>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.

To configure HA:
1. Use three Ethernet cables to directly connect two appliances together using ports eth1, eth2, and eth3.
2. Configure the three connected MQ Appliance ports (on both appliances) as follows:
Interface Purpose IP address/CIDR
eth1 HA group primary interface x.x.x.x/24
