See “Knowing What to Expect in MTA and POA Failover Situations” on page 64.Failover of the Internet Agent itself is more complex. The various clients (POP3, IMAP4, andLDAP) receive an error message that the node is not available. Most of the clients do not attempt toreconnect automatically, so the user must exit the client and restart it to reestablish the connectionafter the failover process is complete. Fortunately, the Internet Agent restarts quickly in its failoverlocation 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 normalprocessing and stops its threads. For a busy Internet Agent, you might need to wait several minutesfor it to shut down properly.4.4 Internet Agent Clustering WorksheetItem Explanation1) Shared Volume for InternetAgent:Cluster Enabled? Yes (highly recommended)Cluster volume IP address NoSpecify the name (cluster_volume) of the shared volume where theInternet 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 istied.For more information, see “Deciding Whether to Cluster-Enable theInternet Agent Volume” on page 70.2) Internet AgentDomain Name:Domain Database Location:Specify a unique name for the Internet Agent domain. Specify thedirectory on the Internet Agent volume where you want to create thenew domain.For more information, see “Planning a Domain for the Internet Agent”on page 70.
