Agent Input/Output Queues In The Domain; Gateways - Novell GROUPWISE 8 - ADMINISTRATION Administration Manual

You can re-create your entire GroupWise system from the primary domain file;
wpdomain.db
however, if the primary domain file becomes unusable, you can no longer make
wpdomain.db
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 622.
MTA Input Queue in the Domain
The MTA input queue in the local domain ( ) is where MTAs for other domains
domain\wpcsin
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 479. 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 ( ) is where the MTA deposits
domain\wpcsout\ads
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 ( ) is, of course, the same as the MTA
domain\wpcsout\ads
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 ( ) is the same as the MTA input queue in the
domain\wpcsin
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/
