opcforwm Message forwarding manager that relieves the
message manager, opcmsgm, of time-consuming tasks
(for example, sending messages to remote managers).
This relief allows the message manager to manage
messages more effectively. On the local “source”
management server, the message forwarding manager
receives data from the message manager (in the form of
messages), the action manager (action responses), and
the display manager (message operations such as
acknowledge, add annotation, and so on). The message
forwarding manager sends data to the message
receiver on the “target” management servers.
opcmsgr Message receiver that collects all messages from
managed nodes. The message receiver is an auxiliary
process of the message manager designed to ensure
quick message acceptance. The message receiver
accepts messages from NCS agents only.
opcmsgrd Similar to opcmsgr. Accepts messages from NCS, DCE,
and Sun RPC agents.
opctss Distribution manager subprocesses that transfer
configuration data to the distribution agent through
TCP/IP.
opcttnsm Trouble ticket and notification service manager
that feeds the external notification interface, as well as
the external trouble ticket interface, with message
attributes. This manager is an auxiliary process of the
message manager designed to ensure high message
throughput. If external instructions are specified for a
message, the trouble ticket and notification service
manager evaluates the help text through the action
manager.
Whenever the trouble ticket and notification service
manager receives a message in its queue, it passes the
message on to the trouble ticket interface or the
external notification service. It does so by forking and
executing the customer-defined program that receives
the message (that is, the ticketing interface or the
notification service). As soon as this program is
finished and exited, a SIGCHLD is sent to the trouble
