Planning A New Clustered Domain - Novell GROUPWISE 8 - INTEROPERABILITY Manual

Parts of your GroupWise system can run in one cluster while other parts of it run in one or more
other clusters.
Parts of your GroupWise system can run in a cluster while other parts run outside of the cluster,
on non-clustered servers.
If you do not have the system resources to run all of your GroupWise system in a clustering
environment, you must decide which parts have the most urgent need for the high availability
provided by clustering. Here are some suggestions:
Post offices and their POAs must be available in order for users to access their GroupWise
mailboxes. Therefore, post offices and their POAs are excellent candidates for the high
availability provided by clustering.
In a like manner, WebAccess provides user access to GroupWise mailboxes across the Internet
through users' Web browsers. It is another good candidate for clustering.
Domains and their MTAs are less noticeable to users when they are unavailable (unless users in
different post offices happen to be actively engaged in an e-mail discussion when the MTA
goes down). On the other hand, domains and their MTAs are critical to GroupWise
administrators, although administrators might be more tolerant of a down server than end users
are. Critical domains in your system would be the primary domain and, if you have one, a hub
or routing domain. These domains should be in the cluster, even if other domains are not.
The Internet Agent might or might not require high availability in your GroupWise system,
depending on the importance of immediate messaging across the Internet and the use of POP3
or IMAP4 clients by GroupWise users.
There is no right or wrong way to implement GroupWise in a clustering environment. It all depends
on the specific needs of your particular GroupWise system and its users.

2.3 Planning a New Clustered Domain

The considerations involved in planning a new domain in a clustering environment are essentially
the same as for any other environment.
Primary Domain: If you are setting up a new GroupWise system in a clustering environment,
you will be creating the primary domain as you complete the tasks in this section. In
preparation, review

Secondary Domain: If your GroupWise system already exists, you will be creating a new
secondary domain. In preparation, review
