EnvoyACP/XF Object States
How to Determine EnvoyACP/XF Object Names
To determine the names assigned to PROCESS and LINE objects, enter one of the
following command at the SCF prompt:
-> LISTDEV TYPE 11
-> LISTDEV ENVOYACX
EnvoyACP/XF Object States
LINE objects can be in the following states:
STARTED
The LINE object enters the STARTED state when the START command completes
successfully.
STOPPED
When a LINE object is in the STOPPED state, there are no links either to or from
the LINE object and the LINE is not ready for normal operation. Application
requests, such as READ, WRITE, CONTROL, and OPEN do not flow while an
object is in the STOPPED state. However, you can alter most configuration
attributes while the object is in the STOPPED state.
SUSPENDED
If the SUSPEND command completes successfully, the LINE object goes into a
SUSPENDED state. In this state, applications cannot establish new opens but the
already established opens are not affected.
An Envoy ACP/XF line enters the suspended state when the line-handling process
cannot download CLIP code to the SWAN box successfully and if the line state
was suspended or started previously. In the suspended or started state, if the line-
handling process gets the controller power-on or process power-on signal, it again
downloads the CLIP code and tries to start the line. The suspended state supports
a multi-system environment. In a multi-system environment, a single command
(SCF START SERVER) from one system will bring up the line, putting the line on
the other system into a suspended state at the same time. The line commands
INFO, STATS, START, STOP, ABORT, and NAMES work normally in the
suspended state. The ALTER LINE command is not allowed in the suspended
state.
DIAGNOSING
The object in the DIAGNOSING state is in a subsystem-defined test mode (entered
through the DIAGNOSE command from OSM).
Note. ENVOYACX is the EnvoyACP/XF subsystem keyword for online help.
