The SHOW CALL_FRAME commands in this SDA session follow a chain of call frames from that specified in the FP of the SDA current process.

SHOW CLUSTER

Displays connection manager and system communications services (SCS) information for all nodes in a cluster.

Format

SHOW CLUSTER {/CSID=csid|/NODE=name|/SCS}

Parameters

None.

Qualifiers

/CSID=csid
Displays VAXcluster system information for a specific VAXcluster member node. The value csid is the cluster system identification number (CSID) of the node to be displayed.⁷
/NODE=name
Displays VAXcluster system information for a specific VAXcluster member node. The value name is the name of the node to be displayed.
/SCS
Displays a view of the cluster as seen by SCS.

Description

By default, the SHOW CLUSTER command provides a view of the VAXcluster system from the perspective of the connection manager. When you use the /SCS qualifier, however, SHOW CLUSTER provides a view of the cluster from the perspective of the port driver or drivers.
VAXcluster as Seen by the Connection Manager

The SHOW CLUSTER command provides a series of displays.
The VAXcluster summary display supplies the following information:

Number of votes required for a quorum
Number of votes currently available
Number of votes allocated to the quorum disk
Status summary indicating whether a quorum is present

The CSB list displays information about the VAXcluster system blocks (CSB) currently in operation; there is one CSB assigned to each node of the cluster. For each CSB, the CSB list displays the following information:

Its address
Name of the VAXcluster node it describes
CSID associated with the node
Number of votes (if any) provided by the node
Its state⁸
Its status

The cluster block display includes information recorded in the cluster block (CLUB), including a list of activated flags, a summary of quorum and vote information, and other data that applies to the cluster from the perspective of the node for which SDA is being run.
The cluster failover control block display provides detailed information concerning the cluster failover control block (CLUFCB), and the cluster quorum disk control block display provides detailed information from the cluster quorum disk control block (CLUDCB).
Subsequent displays provide information for each CSB listed previously in the CSB list display. Each display shows the state and flags of a CSB, as well as other specific node information. (See the Show Cluster utility section of the OpenVMS System Management Utilities Reference Manual for information about the flags for VAXcluster nodes.)
VAXcluster as Seen by the Port Driver

The SHOW CLUSTER/SCS command provides a series of displays.
The SCS listening process directory lists those processes that are listening for incoming SCS connect requests. For each of these processes, this display records the following information:

Address of its directory entry
Connection ID
Name
Explanatory information, if available

The SCS systems summary display provides the system block (SB) address, node name, system type, system ID, and the number of connection paths for each SCS system. An SCS system can be a VAXcluster member, HSC, UDA, or other such device.
Subsequent displays provide detailed information for each of the system blocks and the associated path blocks. The system block displays include the maximum message and datagram sizes, local hardware and software data, and SCS poller information. Path block displays include information that describes the connection, including remote functions and other path-related data.

This example shows a subset of a typical output for the SHOW CLUSTER/SCS command. In this system, there are three nodes (DORIS, GUS, and SOLLY), and there are two HSCs (PINTO and DODGER). After the summary information in the first two screen displays, specific information for each system block and its associated path block is shown.

Note

⁷ You can find the CSID for a specific node in a cluster by examining the CSB list display of the SHOW CLUSTER command. Other SDA displays refer to a system's CSID. For instance, the SHOW LOCK command indicates where a lock is mastered or held by CSID.

⁸ For information about the state and status of nodes, see the description of the ADD command in the Show Cluster utility section of the OpenVMS System Management Utilities Reference Manual.

SHOW CONNECTIONS

Displays information about all active connections between systems communications services (SCS) processes or a single connection. This command displays information that is in the connection descriptor table (CDT).

Format

SHOW CONNECTIONS {/ADDR or /ADDRESS=cdt-address| /NODE=name| /SYSAP=name}

Parameters

None.

Qualifiers

/ADDR or /ADDRESS=cdt-address
Displays information contained in the connection descriptor table (CDT) for a specific connection.⁹
/NODE=name
Displays information contained in the connection descriptor table (CDT) for a specific node.
/SYSAP=name
Displays information contained in the connection descriptor table (CDT) for a specific system application (SYSAP).

Description

The SHOW CONNECTIONS command provides a series of displays.
The CDT summary page lists information regarding each connection on the local system, including the following:

CDT address
Name of the local process with which the CDT is associated
Connection ID
Current state
Name of the remote node (if any) to which it is currently connected

The CDT summary page concludes with a count of CDTs that are free and available to the system.
SHOW CONNECTIONS next displays a page of detailed information for each active CDT listed previously.

This example shows the use of the /SYSAP qualifier to show which nodes in the cluster are connected to SCA$TRANSPORT.

Note

⁹ You can find the cdt-address for any active connection on the system in the CDT summary page display of the SHOW CONNECTIONS command. In addition, CDT addresses are stored in many individual data structures related to SCS connections. These data structures include class driver request packets (CDRPs) and unit control blocks (UCBs) for class drivers that use SCS and cluster system blocks (CSBs) for the connection manager.
