When to Use This Section
This section provides basic information about the different types of processes for
NonStop S-series servers. It gives a brief example of monitoring each type of process
and provides information about the commands available for recovery operations.
Types of Processes
Three types of processes are of major concern to a system operator of a NonStop
S-series server:
•
System processes
•
I/O processes (IOPs)
•
Generic processes
System Processes
A system process is a privileged process that is created during system load and exists
continuously for a given configuration for as long as the processor remains operable.
Examples of system processes include the memory manager, the monitor, and the I/O
control processes.
