SHOW CBB
Displays contents of a Common Bitmask Block.
Format
SHOW CBB address
Parameters
address
The address of the Common Bitmask Block. This is required.
Qualifiers
None.
Description
The contents of the specified common bitmask block are displayed: the
number of valid bits, the interlock state, the unit size and count, and
the current settings for the bits in the bitmask.
Example
|
SDA> SHOW CBB SMP$GS_CBB_ACTIVE_SET
Common Bitmask Block at FFFFFFFF.8180CA00
-----------------------------------------
Valid bits: 00000040 State: 00000000.00000000
Unit count: 0001 Unit size: QUADWORD
Unit bitmask:
........ ........ 00000000 00000001 00000000
|
This example shows the active-CPU common bitmask block for a single-CPU
system.
SHOW CEB
Displays information about Common Event flag Blocks, also known as
Common Event flag clusters.
Format
SHOW CEB [address|/ALL]
Parameters
address
The address of a common event flag block. Detailed information is
displayed for the specified common event flag block.
Qualifiers
/ALL
Specifies that detailed information is to be displayed for each common
event flag block. By default, a one-line summary is output for each
common event flag block.
Description
The contents of one or all common event flag blocks is displayed. In
one-line summary format, the address, name, creator process, reference
count, current settings for the 32 event flags in the cluster, and the
UIC of the cluster are displayed. In detailed format, the address of
the cluster's Object Rights Block (ORB) and the count of waiting
threads are also displayed, with lists of all associated processes and
waiting threads.
You cannot specify both an address and /ALL; they are mutually
exclusive.
SHOW COMMON_EVENT_BLOCK is a synonym for SHOW CEB.
Examples
1. SDA> SHOW CEB

SHOW CLUSTER
Displays connection manager and system communications services (SCS)
information for all nodes in a cluster.
Format
SHOW CLUSTER
{[{/ADDRESS=n|/CSID=csid|/NODE=name}]|/SCS}
Parameters
None.
Qualifiers
/ADDRESS=n
Displays only the OpenVMS Cluster system information for a specific
OpenVMS Cluster member node, given the address of the cluster system
block (CSB) for the node. This is mutually exclusive with the
/CSID=csid and /NODE=name qualifiers.
/CSID=csid
Displays only the OpenVMS Cluster system information for a specific
OpenVMS Cluster member node. The value csid is the cluster
system identification number (CSID) of the node to be displayed. 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 LOCKS
command indicates where a lock is mastered or held by CSID. This is
mutually exclusive with the /ADDRESS=n and /NODE=name
qualifiers.
/NODE=name
Displays only the OpenVMS Cluster system information for a specific
OpenVMS Cluster member node, given its SCS node name. This is mutually
exclusive with the /ADDRESS=n and /CSID=csid
qualifiers.
/SCS
Displays a view of the cluster as seen by SCS.
Description
The SHOW CLUSTER command provides a view of the OpenVMS Cluster system
from either the perspective of the connection manager (the default
behavior), or from the perspective of the port driver or drivers (if
the /SCS qualifier is used).
OpenVMS Cluster as Seen by the Connection Manager
The SHOW CLUSTER command provides a series of displays.
The OpenVMS Cluster 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 or not a quorum is present
The CSB list displays information about the OpenVMS
Cluster system blocks (CSBs) currently in operation; one CSB is
assigned to each node of the cluster. For each CSB, the CSB
list displays the following information:
- Address of the CSB
- Name of the OpenVMS Cluster node it describes
- CSID associated with the node
- Number of votes (if any) provided by the node
- State of the CSB
- Status of the CSB
For information about the state and status of nodes, see the
description of the ADD CLUSTER command of the SHOW CLUSTER utility in
the HP OpenVMS System Management Utilities Reference Manual.
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 the
SDA is being run.
The cluster failover control block display provides
detailed information concerning the cluster failover control block
(CLUFCB). 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 ADD MEMBER command of the SHOW CLUSTER utility in the HP OpenVMS System Management Utilities Reference Manual
for information about the flags for OpenVMS Cluster nodes.)
If any of the qualifiers /ADDRESS=n, /CSID=csid, or
/NODE=name are specified, then the SHOW CLUSTER command
displays only the information from the CSB of the specified node.
OpenVMS Cluster 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 OpenVMS Cluster member, storage controller, 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 illustrates the output of the SHOW CLUSTER /SCS command.
SHOW CONNECTIONS
Displays information about all active connections between System
Communications Services (SCS) processes or a single connection.
Format
SHOW CONNECTIONS [{/ADDRESS=cdt-address |/NODE=name |/SYSAP=name }]
Parameters
None.
Qualifiers
/ADDRESS=cdt-address
Displays information contained in the connection descriptor table (CDT)
for a specific connection. 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.
/NODE=name
Displays all CDTs associated with the specified remote SCS node name.
/SYSAP=name
Displays all CDTs associated with the specified local 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.
