SolutionStarting with IDM 13.2, Identity
Manager can now support more than two Identity Manager servers in the
same cluster, enabling data and configuration
sharing.Virtual router redundancy protocol(VRRP) is a solution for this.
IP
Address high availability allows a single virtual IP Address to be
defined and shared between two Identity Manager Servers so that in the
event of failure, the Virtual IP address is picked up by the backup
server of the pair which then continues to service
requests.
Identity Manager provides High Availability
between 2 nodes in a local cluster belonging to the same subnet by using
the VRRP Protocol. IP Address High Availability can be performed by
following the steps below.
1.
From the Identity Manager Interface go to Server
--> Cluster Configuration and click on the IP
Address High Availability
tab.
2. IP Address High Availability uses the
VRRP protocol to allow two Identity Managers to provide active/backup
services for a shared IP Address. Devices are configured to use this
virtual IP Address which by default runs on the Master node. In the
event of the Master node failing the Backup node will take over the IP
address and service requests.
