SHOW BUGCHECK

Displays the value, name, and text associated with one or all bugcheck codes.

Format

SHOW BUGCHECK {/ALL (d)|name|number}

Parameters

name
Value, name, and text of the named bugcheck code.
number
Value, name, and text of the requested bugcheck code.
The parameters name and number and the qualifier /ALL are all mutually exclusive.

Qualifier

/ALL
Displays complete list of all the bugcheck codes, giving their value, name, and text. It is the default.

Description

The SHOW BUGCHECK command displays the value, name, and text associated with bugcheck codes.

Examples

#1
SDA> SHOW BUGCHECK 100 0100 DIRENTRY ACP failed to find same directory entry

The SHOW BUGCHECK command in this example shows the requested bugcheck by number.

#2
SDA> SHOW BUGCHECK DECNET 08D0 DECNET DECnet detected a fatal error

The SHOW BUGCHECK command in this example shows the requested bugcheck by name.

SDA> SHOW BUGCHECK
BUGCHECK codes and texts
------------------------
0008  ACPMBFAIL      ACP failure to read mailbox
0010  ACPVAFAIL      ACP failure to return virtual address space
0018  ALCPHD         Allocate process header error
0020  ALCSMBCLR      ACP tried to allocate space already allocated
   .
   .
   .

The SHOW BUGCHECK command in this example shows the requested bugcheck by displaying all codes.

SHOW CALL_FRAME

Displays the locations and contents of the quadwords representing a procedure call frame.

Format

SHOW CALL_FRAME {[starting-address]|/NEXT_FP}

Parameter

starting-address
Expression representing the starting address of the procedure call frame to be displayed. The default starting-address is the contents of the FP register of the SDA current process.

Qualifier

/NEXT_FP
Displays the procedure call frame starting at the address stored in the FP longword of the last call frame displayed by this command. You must have issued a SHOW CALL_FRAME command previously in the current SDA session in order to use the /NEXT_FP qualifier to the command.

Description

Whenever a procedure is called, information is stored on the stack of the calling routine in the form of a procedure call frame. The SHOW CALL_FRAME command displays the locations and contents of the call frame. The starting address of the call frame is determined from the specified starting address, the /NEXT_FP qualifier, or the address contained in the SDA current process FP register (the default action).
When using the SHOW CALL_FRAME/NEXT_FP command to follow a chain of call frames, SDA signals the end of the chain by the following message:
%SDA-E-NOTINPHYS, 00000000.00000000 : not in physical memory
This message indicates that the saved FP in the previous call frame has a zero value.

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 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 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.

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.
