1–6 117143 SNAX Creator-2 Configuration and Control Manual
Section 3, “Objects for SNAX Creator-2,” defines the hierarchy, object types, and
naming conventions for SNAX Creator-2 objects.
Some SCF commands include an optional SUB parameter that refers to all subordinate
objects. The SUB parameter has the form:
SUB [ subtype ]
This parameter selects the subordinate objects the command affects. subtype can be
a subordinate object type or one of the keywords NONE, ALL, or ONLY.
If a subordinate object type is named, only objects of that type are affected. NONE
specifies that the named object is affected, but none of its subordinate objects are
affected. ALL specifies that the named object and its subordinate objects are affected.
ONLY specifies that only the subordinate objects are affected. If subtype is omitted,
NONE is assumed.
For example, the following command displays the names of all objects controlled by
the SUBSYS object $CREA:
NAMES SUBSYS $CREA.*, SUB ALL
Object States
Each object has an operational state, such as STOPPED or STARTED. The set of states
an object can assume varies depending on the object type. Some subsystem objects are
always in the same state: for example, a SNAX Creator-2 SESSION object is always in
the STARTED state.
The following states are recognized by SCF for SNAX Creator-2 (refer to Section 3,
“Objects for SNAX Creator-2,” for detailed descriptions of each state):
State Description
STARTED The object is initialized and ready.
STARTING The object is being initialized and is attempting to start.
STOPPED The object is not ready for normal operations. STOPPED is equivalent to
down, not ready, or killed.
STOPPING The object is being stopped. No new activity is initiated.
SUSPENDED The object is suspended. In the case of SNAX Creator-2, only SU objects
can be in the suspended state. The object is unusable pending operator
intervention
The operational state of an object can affect the use of SCF commands to operate on the
object. For example, you can use the ALTER SU command only when the SU object is
in the STOPPED state.
