Generic Processes
•
Monitors its processes to immediately re-create any process that has terminated (if
it was configured to be persistent).
The principal subsystems used for H-series system configuration are listed in
Table 1-1. The manuals for each of these subsystems are given in Where to Get More
Information on page -xii. These subsystems are generic processes that are started and
maintained by the $ZPM persistence manager, whereas the older subsystems are
started by the operator, usually in the form of separate RUN commands in a TACL
command file.
Generic Processes
A key component of H-series configuration architecture is generic processes that can
be created by the operating system or a user. Examples of generic processes created
by the operating system are the subsystem managers listed in Table 1-1. Examples of
generic processes created by a user can be an HP program, a third-party program, or
a user-written program that you configure to be controlled by the operating system.
$ZPM starts and monitors all generic processes on systems running H-series RVUs.
for more information about generic processes, refer to the SCF Reference Manual for
the Kernel Subsystem
.
