Two servers running SUSE Linux Enterprise Server (SLES) 12 SP1 64-bit, SLES 11 SP4 64-bit, or RedHat Enterprise Linux (RHEL) 6.8 64-bit for nodes installed with all the dependent libraries. For more information, see section on RHEL.
Identity Manager 4.6 components installed.
All the nodes have the same application server clocks. The easiest way to ensure this is to configure the nodes to use the same network time server for time synchronization using NTP.
The cluster nodes reside in the same subnet.
A failover proxy or a load balancing solution is installed on a separate computer.
