You can re-create your entire GroupWise system from the primary domain
wpdomain.db
file;
however, if the primary domain
wpdomain.db
file becomes unusable, you can no longer make
administrative updates to your GroupWise system.
Secondary domains are automatically synchronized to match the primary domain.
40.3.2 Agent Input/Output Queues in the Domain
Each domain contains agent input/output queues where messages are deposited and picked up for
processing by the MTA.
For a mapped or UNC link between domains, the MTA requires read/write access rights to its input/
output queues in the other domains. For a TCP/IP link, no access rights are required because
messages are communicated by way of TCP/IP.
For illustrations of the processes presented below, see Section 40.6, “Message Flow between
Domains and Post Offices,” on page 608 .
MTA Input Queue in the Domain
The MTA input queue in the local domain (
domain \wpcsin
) is where MTAs for other domains
deposit user messages for the local MTA to route to local post offices or to route to other domains.
Thus the MTA input queue in the local domain is the output queue for the MTAs in many other
domains.
The MTA does not have an output queue for user messages in the local domain. Because its primary
task is routing messages, the local MTA has output queues in all post offices in the domain. See
“POA Input Queue in the Post Office” on page 467 . The local MTA also has output queues in all
domains to which it is directly linked.
MTA Output Queue in the Domain
The MTA output queue in the local domain (
domain \wpcsout\ads
) is where the MTA deposits
administrative messages from other domains for the MTA admin thread to pick up.
MTA Admin Thread Input Queue in the Domain
The MTA admin thread input queue (
domain \wpcsout\ads
) is, of course, the same as the MTA
output queue in the local domain. The MTA admin thread picks up administrative messages
deposited in the queue by the MTA and updates the domain database.
MTA Admin Thread Output Queue in the Domain
The MTA admin thread output queue (
domain \wpcsin
) is the same as the MTA input queue in
the local domain. The MTA admin thread deposits administrative messages in the queue for
replication to other domains.
40.3.3 Gateways
Gateways are installed and configured at the domain level of your GroupWise system. For a list of
gateways, see the
GroupWise Gateways Documentation Web site (http://www.novell.com/
documentation/gwgateways) .
