Remarks on JP1/AJS3 operation in a cluster system that uses three or more nodes:

JP1/AJS3 operates in a logical host environment managed by cluster software (with a shared disk and logical IP address). The operation does not differ depending on the number of nodes.

There will be no particular problem with JP1/AJS3 operation in a cluster system consisting of three or more nodes, as long as the logical host environment is normally managed by cluster software.
