Discussion

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.

Review system categorization to determine if redundancy is a requirement. If the system categorization does not specify redundancy requirements, this requirement is NA.

On each member of the HA pair:
Establish an SSH command line session as an admin user.

To access the MQ Appliance CLI, enter:
mqcli

To run the dspmq command, enter:
dspmq -s -o ha 

One of the appliances should be running as primary, the other as secondary.

If HA is not configured and the primary and secondary running, this is a finding.
