Editing Cluster Details - Novell ACCESS MANAGER 3.1 SP2 - IDENTITY SERVER GUIDE 2010 Manual

1.1.5 Editing Cluster Details

The Cluster Details page lets you manage the configuration's cluster details, health, alerts, and
statistics.
1 In the Administration Console, click Devices > Identity Servers.
2 Click the name of the cluster configuration.
3 Select from the following actions:
Details: To modify the cluster name or its settings, click Edit, then continue with
Health: To view the health of the cluster, click the Health tab.
Alerts: To view the alerts generated by members of the cluster, click the Alerts tab.
Statistics: To view the statistics of the cluster members, click the Statistics tab.
4 Modify the following fields as required:
Cluster Communication Backchannel: Specify a communications channel over which the
cluster members maintain the integrity of the cluster. For example, this TCP channel is used to
detect new cluster members as they join the cluster, and to detect members that leave the
cluster. A small percentage of this TCP traffic is used to help cluster members determine which
cluster member would best handle a given request. This back channel should not be confused
with the IP address/port over which cluster members provide proxy requests to peer cluster
members.
Port: Specify the TCP port of the cluster back channel on all of the Identity Servers in the

cluster. 7801 is the default TCP port.
Because the cluster back channel uses TCP, you can have cluster members on different
networks. However, firewalls must allow the ports specified here plus one to pass through.
You need to open two ports for each cluster, for example, 7801 and 7802.
Encrypt: Encrypts the content of the messages that are sent between cluster members.
