Knowing What To Expect In An Internet Agent Failover Situation; Internet Agent Clustering Worksheet - Novell GROUPWISE 7 - INTEROPERABILITY GUIDE Manual

Recording Cluster-Specific Information about the Internet Agent
With the contents of the Internet Agent domain still displayed:
1 Right-click the Internet Agent object, then click Properties.
2 Click GroupWise, then click Identification.
3 In the Description field, record the secondary IP address of the cluster-enabled Internet Agent
domain volume and the cluster-unique port numbers used by the Internet Agent.
This information appears on the Internet Agent console, no matter which node in the cluster it
is currently running on.

4.3.2 Knowing What to Expect in an Internet Agent Failover
Situation
The failover behavior of the MTA for the Internet Agent domain is the same as for an MTA in a
regular domain. See
Failover of the Internet Agent itself is more complex. The various clients (POP3, IMAP4, and
LDAP) receive an error message that the node is not available. Most of the clients do not attempt to
reconnect automatically, so the user must exit the client and restart it to reestablish the connection
after the failover process is complete. Fortunately, the Internet Agent restarts quickly in its failover
location so users can reconnect quickly.
As with the MTA and the POA, migration of the Internet Agent takes longer than failover. In fact,
the Internet Agent can seem especially slow to shut down properly as it finishes its normal
processing and stops its threads. For a busy Internet Agent, you might need to wait several minutes
for it to shut down properly.

Explanation
Specify the name (cluster_volume) of the shared volume where the
Internet Agent domain will be created.
For cluster-enabling, specify the IP addresses of the virtual server
(volume_SERVER.cluster) to which the cluster-enabled volume is
tied.

Specify a unique name for the Internet Agent domain. Specify the
directory on the Internet Agent volume where you want to create the
new domain.
