Making Important Processes Persistent

You can make important system processes, such as the Expand manager process or

the Subsystem Control Point (SCP) process, start automatically at system load and be

persistent (that is, restart automatically if stopped abnormally) by creating them as

generic processes in the system configuration database and specifying the

AUTORESTART parameter.

This example SCF command file adds persistent generic processes for the CLCI

TACL, Expand manager, and SCP processes. This file can be invoked by the following

TACL command:

> SCF / IN GPADD /

== This file is GPADD

== Adds the CLCI TACL, Expand manager, and SCP processes as generic

== processess.
