Kernel Subsystem

Before using commands listed in Table 2-3, type this command to make the Kernel subsystem the default object:

> SCF ASSUME PROCESS $ZZKRN

Generic processes are part of the SCF Kernel subsystem. Generic processes can be created by the operating system or by a user. Examples of generic processes created by the operating system are the Kernel, SLSA, the storage subsystem, and WAN subsystem manager processes. Examples of generic processes created by a user are a Pathway program, a third-party program, or a user-written program that you configure to be controlled by the operating system. The $ZPM persistence manager starts and monitors all generic processes.
