The MQ Appliance messaging server, when categorized as a high level system, must be in a high-availability (HA) cluster.
An XCCDF Rule
Description
<VulnDiscussion>A high level system is a system that handles data vital to the organization's operational readiness or effectiveness of deployed or contingency forces. A high level system must maintain the highest level of integrity and availability. By HA clustering the messaging server, the hosted application and data are given a platform that is load-balanced and provided high-availability. Rudimentary instructions for determining if HA is set up are included here. To ensure proper configuration, system HA design steps must be taken and implemented. Reference vendor documentation for complete instructions on setting up HA: https://ibm.biz/BdicC7 Note: The queue manager’s data (queues, queue messages etc.) are replicated from the appliance in the primary HA role (first appliance) to the appliance in the secondary HA role (second appliance).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

2. Configure the three connected MQ Appliance ports (on both appliances) as follows:
Interface Purpose IP address/CIDR
