SCF Commands
SCF Commands
Many SCF commands operate on the objects belonging to a subsystem. For example,
you can use the INFO LINE command to display the current attribute values for an
EnvoyACP/XF line, then use the ALTER LINE command to change those attribute
values.
Several commands display and change SCF line attributes. For example, the OUT
command controls the files used for display output. The ASSUME command sets the
default object type and object name.
You can use the HELP command interactively within SCF to display a list of the
available SCF commands and to request additional, specific information, such as
command syntax.
Commands that operate on the EnvoyACP/XF subsystem objects are described in
Section 5, Subsystem Control Facility (SCF) Commands for EnvoyACP/XF.
Commands such as OUT, ASSUME, and HELP are not subsystem-specific and are
described in the SCF Reference Manual for G-Series RVUs and the SCF Reference
Manual for H-Series RVUs.
Sensitive and Nonsensitive Commands
Because some commands can have detrimental effects if improperly used, special
qualification is required to use them. These commands are “sensitive commands.”
Commands that request information or status but do not affect operation are
“nonsensitive commands.”
Only a user who has super-group access, the owner of the subsystem, or a member of
the group of the owner of the subsystem can issue a sensitive command. The owner of
a subsystem is the user who started that subsystem (or any user whose application ID
is the same as the server ID).
Anyone can use a nonsensitive command.
General Command Format
An SCF command always begins with a keyword that identifies it (such as ADD,
START, or STATS).
For SCF commands that pertain to an object, an object type and an object name follow
the keyword. For example, the following command aborts the line object named
EXF01:
-> ABORT LINE $EXF01
To get additional information, follow the object name with a comma and the attributes
required to specify the action. For example, the following command changes the value
of the SPEED attribute for an EnvoyACP/XF line named $XF1:
-> ALTER LINE $XF1 , SPEED 9600
