The WebLogic Managed Server instances of the cluster were created in the previous recipe but a Listen Address value was not assigned to any of it.
The objective of this recipe is to assign a unique hostname or alias as the Listen Address value for each of the Managed Servers instead of assigning the prod01, prod02 hostnames or the IP address.
For the cluster PROD_Cluster the FQDNs: prodsrv01.domain.local, prodsrv02.domain.local, prodsrv03.domain.local, and prodsrv04.domain.localwill be used as the listen addresses. For example, PROD_Server01, PROD_Server02, PROD_Server03, and PROD_Server04, will be used respectively.
From the WebLogic configuration perspective, it doesn't make any difference if the addresses prodsrv01.domain.local, prodsrv02.domain.local, prodsrv03.domain.local, and prodsrv04.domain.local point to the IP addresses of the machines prod01 and prod02 or to
Virtual IP addresses (VIP).
