States
The object name for an SU object usually has two parts: the name of the line to which
the SU has been added, and the unique name of the subdevice itself. The subdevice
part of the name begins with a pound sign (#) and includes up to seven alphanumeric
characters. For example, an SU object might have the name $AMTR.#PC, where
$AMTR is the name of the line.
There are many other object types and object names used in SCF. The objects
relevant to the AM3270 and TR3271 subsystems are described later in this manual.
Subordinate Objects
Some subsystems are structured hierarchically, with a group of objects of one type
logically subordinate to objects of another type. For example, a number of subdevices
could be configured on a single line. Some SCF commands include a SUB parameter
that refers to all subordinate objects.
The SUB parameter has the following form:
SUB [ subtype ]
This parameter selects the subordinate objects affected by the command. The
subtype can be a subordinate object type or one of the keywords ONLY, NONE, or
ALL. If a subordinate object type is named, only objects of that type are affected. ONLY
specifies that only the subordinate objects are affected. ALL specifies that the named
object and the subordinate objects are affected. If subtype is omitted, ALL is
assumed.
States
Objects can have operational states, such as STOPPED or STARTED. The exact
sequence of states an object goes through varies from object to object and from
subsystem to subsystem. SCF commands for the AM3270 and TR3271 subsystems
recognize two states: STOPPED and STARTED. The states that apply to AM3270 and
TR3271 are described below.
The operational state of an object at a given instant is important. For example, some
commands have no effect on objects when those objects are in certain states, but can
affect the objects when they are in other states.
The following states are recognized by the AM3270 and TR3271 subsystems:
State Description
STOPPED The object is not ready for normal operations. STOPPED is equivalent
to down, not ready, or killed.
STARTED The object is initialized and ready for normal data traffic.
