X25AM Subsystem Objects

This section describes the following topics:

•

Object types and object names

•

Object states

•

Object attributes and attribute specifiers

•

Frequently performed tasks on X25AM objects

Object Types and Object Names

You can manipulate the X25AM subsystem using SCF commands that act on one or

more X25AM subsystem objects. Each object has an object type and an object name.

The object type categorizes the object; the object name uniquely identifies each object

within the subsystem.

Object-Type Definition

An object-type is a subsystem-specific keyword that identifies the type of object.

LINE, null, PROCESS, and SU are the object-types for the X25AM subsystem. If

you omit the object-type, the X25AM subsystem may attempt to determine the

object-type. If an attempt to determine the object-type fails, X25AM displays an

error message. Refer to Appendix C, X25AM Error Messages.

Object-Type Hierarchy

The X25AM object types supported by SCF, in hierarchical order, are PROCESS,

LINE, and SU. The NAMES and VERSION commands require no object type. The

hierarchy is important when issuing commands to the X25AM subsystem for

processing. For example, because the LINE object type is subordinate to the

PROCESS object type, any commands pertaining to a LINE object can be issued only

when the PROCESS object is in the STARTED state.

In summary, the object types used by the X25AM subsystem are:

Figure 4-3 on page 4-7 shows the hierarchy of object types for the X25AM subsystem.

PROCESS Refers to an X25AM I/O process running on a

NonStop NS-series or NonStop S-series server.

LINE Refers to a data communications line connected through a

modem to an X.25 network. The LINE object name is the same

as that of the PROCESS object; for example, $X25PM. For

G-series or H-series RVUs, one line supports from 1 through

510 subdevices.

SU Refers to an X25AM subdevice associated with a line.

Note. The VERSION and NAME commands require no object type.
