Generic Processes
Each subsystem manager or monitor process is started by the $ZPM persistence
manager process at system load and has the following functions:
•
Creates I/O processes and other manager processes within the subsystem
•
Configures subsystem objects such as adapter hardware and the ServerNet
addressable controllers (SACs) supported by those adapters
•
Identifies the names of processes that must be reserved at system load
•
Monitors its processes to immediately re-create any process that has terminated (if
it was configured to be persistent)
Each configuration manual listed in the NonStop S-Series Planning and Configuration
Guide describes a subsystem, the objects the subsystem supports, and how to
configure those objects.
You can display information about the following generic processes for G-series RVUs
that are subsystem managers or monitor processes.
Generic Processes
Generic processes can be created by the operating system or by a user. Examples of
generic processes created by a user are an HP program, a third-party program, or a
user-written program that you configure to be controlled by the operating system.
When the system is started, all generic processes that are configured to be persistent
are started automatically by the $ZPM persistence manager or by the subsystem
manager, which is started by $ZPM.
See the SCF Reference Manual for the Kernel Subsystem for more information about
generic processes.
