Overview
The default SCP process, known to the system as $ZNET, is a generic process that
provides access for application programs (local or remote) to monitor and control a
SCF subsystem. If $ZNET is not running, SCF starts its own SCP process (which is
removed from the system when SCF is stopped).
SCF automatically opens and closes the SCP. In most cases, the default SCP is the
only one you need. If you need to establish an SCF session with a specific SCP other
than the default SCP, you can start additional SCP processes by using one of:
•
An SCF RUN command
•
A TACL RUN command (as described in the Subsystem Control Point (SCP)
Reference Manual )
•
A generic process (as described in SCF Reference Manual for the Kernel
Subsystem )
To select a running SCP other than the default SCP, use the OPEN command
described in the SCF Reference Manual for G-Series RVUs .
During the initialization of a system that has a large number of communications
devices, it can be advantageous to have multiple SCF processes and multiple SCP
processes running at one time (such use is limited to system managers and
super-group (255,n) users).
