Interactive Interfaces
PROCESS Object
The PAM PROCESS object determines whether a PAM process is running in the
system. The PAM PROCESS object provides the interface to the ServerNet LAN
Systems Access (SLSA) subsystem for Ethernet and token ring. The PAM process
also generates EMS messages.
A PAM process is associated with a LIF in the SLSA subsystem. When PAM is started
either through a TACL RUN command or through the persistence manager, the LIF is
associated with the PAM process. The persistence manager is part of the HP NonStop
operating system and starts generic processes including subsystem managers such as
the PAMMAN process during the system load and any time the processors on which a
PAM process is defined come back up after a failure.
For more information about the SLSA subsystem and LIFs, see the LAN Configuration
and Management Manual. For information about the persistence manager, see the
SCF Reference Manual for the Kernel Subsystem.
LINE Object
The LINE object controls access to the specified LIF for a LAN adapter such as the
Ethernet 4 ServerNet adapter (E4SA). The name of the LINE object and the PAM
process object is always the same. An example of a LINE name is $PAM.
PORT Object
The PORT object is a programmatic interface that provides applications with link-level
service access points (LSAPs). Through the LSAPs, a client or application process that
is running on a NonStop S-series server or on an Integrity NonStop NS-series server
can access a LAN.
