The channel called RTR$DEFAULT_CHANNEL is open as a server channel.
The channel called CLI_CHN is open as a client channel.
The channel called CLI_CHN2 is open as a client channel, and has been opened by another process (in another window).

SHOW CLIENT

Display information about client channels.

Format

SHOW CLIENT

Command Qualifiers	Defaults

The SHOW CLIENT command displays information about client channels.
Information such as PID, key range, state, event mask and event name are displayed.

Qualifiers

/CLUSTER

/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither /NODE nor /CLUSTER is specified then the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.
Note: In environments that do not support clustering, use of the /CLUSTER qualifier will cause the relevant command to be executed on the local node only.
/IDENTIFICATION=process-id

/NOIDENTIFICATION (D)
Specifies the PID of the process for which information is displayed. The default (/NOIDENTIFICATION) displays information for all clients.
/FACILITY

/FACILITY="*" (D)
Specifies the facility name for which information should be displayed.
By default, information is displayed for all Facilities.
/FULL

none (D)
Specifies a detailed listing of client information.
/NODE[=node-list]

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

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

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 wild cards ("*" 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 2.6, 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 then the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.
Note: In environments that do not support clustering, use of the /CLUSTER qualifier will cause 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(s) of the the node where the command is executed, and

Whether router call-out servers or backend call-out servers have been configured,
Whether load balancing has been configured,
Whether quorum check is being handled on this node.
Whether 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 then all counters are displayed. Counter-name may contain wild card 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. 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-list (D)
Specifies that the command is executed on all nodes specified in node-list. If node-list is omitted then the command is executed only on the node where the command was issued.
/OUTPUT[=file-spec]

/OUTPUT=stdout (D)
Specifies that the resulting information is written to the file file-spec. If /OUTPUT or file-spec is omitted then 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.

Show all facilities in detail.
The facility's name.
The 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.
The 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.
(5) The 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.
The second link shown (to node "airola") shows that it is a frontend, and is a frontend to router connection.
