Deciding Where To Install The Internet Agent And Its Mta; Deciding Whether To Run The Internet Agent And Its Mta In Protected Memory - Novell GROUPWISE 8 - INTEROPERABILITY Manual

If the Internet Agent has a large number of nodes on its failover path, you could configure the
Internet Agent to send outgoing messages to a relay host, which would then send them out through
the firewall using its own IP address rather than the address of the particular node where the Internet
Agent was running. This reduces the amount of modification to your firewall required to set up the
Internet Agent. However, if the relay host goes down, outgoing messages are delayed.
As another alternative, you can configure the Internet Agent to use its secondary IP address for
sending as well as receiving messages. Setup instructions for this configuration are provided in
"Forcing Use of the Internet Agent Secondary IP Address" on page
after installing the Internet Agent.
In preparation for installing the Internet Agent, configure your firewall as needed to handle the
Internet Agent's use of primary and secondary IP addresses when sending and receiving messages.

4.1.6 Deciding Where to Install the Internet Agent and Its MTA

As with the MTA and the POA, you can choose to install the Internet Agent and its MTA to the
sys:\system
For a discussion of these alternatives, see
page 31, which describes the issues in the context of planning MTA and POA installations. If you
only have one Internet Agent for your GroupWise system with several servers in its failover path, it
is an easy choice: Install it once to a

4.1.7 Deciding Whether to Run the Internet Agent and Its MTA
in Protected Memory
As with the MTA and the POA, you can choose whether to run the Internet Agent in protected
memory. For a review of the benefits of protected memory, see

MTA and POA installations.
You might think that protected memory is not necessary if you have only one Internet Agent for
your GroupWise system because it could never fail over to a node where another Internet Agent was
running. However, because the Internet Agent in a cluster is installed into its own domain with its
own MTA, this MTA could fail over to a node where another MTA was already running. Therefore,
it is safest to load the MTA into protected memory. Loading the Internet Agent into protected
memory is also recommended. Load each agent into its own memory space and mark each memory
space as restartable.
