SHOW CHANNEL

The SHOW CHANNEL command shows the names and state of channels that have been opened using the CLI API.

Format

SHOW CHANNEL [channel-name]

Command Qualifiers	Defaults
/ALL_WINDOWS	/NOALL_WINDOWS
/CLUSTER	/NOCLUSTER
/NODE[=node-list]	/NODE=default-node
/OUTPUT[=filespec]	/OUTPUT=stdout

Description

The SHOW CHANNEL command shows the channel type (client or server), the channel name and owner process-id for channels opened using the CLI API.

Parameters

channel-name
Specifies the name of the channel to be displayed. channel-name can contain wildcards. If channel-name is omitted, all declared channels for this window (terminal or virtual terminal) are displayed.

Qualifiers

/ALL_WINDOWS

/NOALL_WINDOWS
Specifies that channels opened in all windows (terminals or virtual terminals) are shown.
/CLUSTER

/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither /NODE nor /CLUSTER is specified, the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered, the command is executed only on the node where the command was issued.

Note
In environments that do not support clustering, the /CLUSTER qualifier causes the relevant command to be executed on the local node only.

/NODE[=node-list]

/NODE=default-node (D)
Specifies that the command is executed on all nodes specified in node-list . If node-list is omitted, the command is executed only on the node where the command was issued.
/OUTPUT[=filespec]

/OUTPUT=stdout (D)

/FULL	/NOFULL
/LINKS/BRIEF	/NOLINKS/NOBRIEF
/NODE[=node-list]	/NODE=default-node
/OUTPUT[=filespec]	/OUTPUT=stdout
/STATE	/NOSTATE

Description

The SHOW FACILITY command shows the names, configuration and status of facilities on the node where the command is executed. If no qualifiers are used, only the facility name or names and the roles in the facility on the node are displayed.

Parameters

facility-name
Specifies the name of the facility you want to display. Facility-name may contain wildcards (* and %), in which case all matching facilities will be displayed. If facility-name is omitted, all configured facilities are displayed.

Qualifiers

/BALANCE

/NOBALANCE (D)
Specifies that the load balancing status of the facility is also displayed. See Section 2.7, Router Load Balancing for details of load balancing.
/CLUSTER

/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither /NODE nor /CLUSTER is specified, the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered, the command is executed only on the node where the command was issued.

Note
In environments that do not support clustering, the /CLUSTER qualifier causes the relevant command to be executed on the local node only.

/CONFIGURATION

/NOCONFIGURATION (D)
Specifies that the facility configuration is to be displayed. The configuration information indicates the role of the node where the command is executed, and whether:

Router callout servers or backend callout servers have been configured
Load balancing has been configured
Quorum check is being handled on this node
Reply consistency check for replayed messages is enabled

/COUNTER[=counter-name]

/NOCOUNTER (D)
Specifies that the facility counters are displayed. Counter-name is the name of the counter. If counter-name is omitted, all counters are displayed. Counter-name may contain wildcard characters.
/FULL

/NOFULL (D)
Equivalent to specifying /CONFIGURATION , /STATE and /LINK .
/LINKS

/NOLINKS (D)
Lists all links to connected nodes in the facility (including the node where the command is executed).
If the /BRIEF qualifer is used, SHOW FACILITY/LINKS/BRIEF, the facility name is displayed, followed by one or more lines showing the name of each link followed by the link's roles and their status in parentheses.
RTR> SHOW FACILITY/LINKS/BRIEF Facilities on node NODEA at Wed Nov 03 11:115:47 1999 BOVRIL (Backend coordinator, Router quorate, Frontend connected>
Backend nodes can be either connected, quorate, or coordinator. Router nodes can be either connected, quorate, or current (current is only seen from a frontend).
If the /BRIEF qualifier is not used, the following information is shown for each link:

Whether the node on this link is active as frontend, router or backend roles.
What kind link is active, that is:

frontend to router
router to frontend
router to backend
backend to router

Whether the router and backend roles are quorate
Whether the router role is the current router for the frontend
Whether the backend role is acting as a load balancing coordinator

/NODE[=node-list]

/NODE=default-node (D)
Specifies that the command is executed on all nodes specified in node-list . If node-list is omitted, the command is executed only on the node where the command was issued.
/OUTPUT[=filespec]

/OUTPUT=stdout (D)
Specifies that the resulting information is written to the file filespec . If /OUTPUT or filespec is omitted, the standard or default output is used.
/STATE

/NOSTATE(D)
Specifies that the state of the facility is displayed.
On nodes having a backend or router role, the quorum status is shown. Also, the current quorum threshold is shown (default quorum value is shown as zero), and the minimum broadcast rate (if it has been set).
On a frontend, this qualifier can be used to find out whether the node is currently connected to a router.

Shows all facilities in detail.
Facility's name.
Facility's configured roles on this node. In this example, the node is a router and a backend; load balancing, router callouts and backend callouts are not enabled.
Facility's state. The router and backend roles are quorate. (Quorate means that this node's view of the availability of the other nodes in the configuration matches that of the other backends and routers. A facility that is not in the quorate state is effectively unusable.) The quorum threshold is at the default (zero) and no minimum broadcast rate has been set.
Facility's links. The first link shown (to node bronze i.e. itself) shows that it is a router, connected to the backend, and the router is quorate. The router is not current because there is no frontend on this connection. The link is also a backend, connected to the router, and this backend is quorate. This backend would also be the backend coordinator if load balancing was enabled.
Second link shown (to node airola) shows that it is a frontend, and is a frontend to router connection.
