5.2.6 Deciding Whether to Run the WebAccess Agent and Its
MTA in Protected Memory
As with the MTA and the POA, you can choose whether to run the WebAccess Agent in protected
memory. For a review of the benefits of protected memory, see
“Deciding Whether to Run the
Agents in Protected Memory” on page 36 , which describes the issues in the context of planning
MTA and POA installations.
You might think that protected memory is not necessary if you have only one WebAccess Agent for
your GroupWise system because it could never fail over to a node where another WebAccess Agent
was running. However, because the WebAccess 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 WebAccess Agent and its MTA into protected memory. Load each
agent into its own memory space and mark each memory space as restartable.
5.2.7 Planning the MTA Installation
Follow the instructions in “Planning the NetWare Agent Installation” on page 37 , then return to this
point. After you follow the instructions, you will have a filled-out NetWare Agent Worksheet to use
when you install the MTA.
IMPORTANT: Do not install the NetWare MTA until you are instructed to do so in Section 5.3,
“Setting Up WebAccess in a Cluster,” on page 93 .
5.2.8 Planning the WebAccess Installation
Aside from the cluster-specific issues discussed in the preceding sections, the considerations
involved in planning to install WebAccess are the same in a clustering environment as for any other
environment. Review “
Planning GroupWise WebAccess ”, then print and fill out the “ GroupWise
WebAccess Installation Worksheet ” in “ Installing GroupWise WebAccess ” in the GroupWise 7
Installation Guide . When you set up WebAccess in a cluster, you install the WebAccess Agent and
the WebAccess Application in two separate steps:

WEBACCESS CLUSTERING WORKSHEET
Under Item 5: MTA Installation Location and Item 7: WebAccess Agent Installation Location , mark
whether you will install the WebAccess Agent and its MTA to
sys:\system
on each node in the
cluster or to a vol :\system directory on the WebAccess Agent volume. Also specify where the MTA
startup file will be stored.
WEBACCESS CLUSTERING WORKSHEET
Under Item 8: Load WebAccess Agent and Its MTA in Protected Memory? , mark whether you need to
run the WebAccess Agent and its MTA in protected memory. If you do, provide a protected memory
address space name for each agent.
