Parameter
ident
The name of the table or the namespace structure to be displayed. If an
ident is given, /ADDRESS cannot be specified.
Qualifier
/ADDRESS = address
The physical address of the table entry or virtual address of a
namespace structure to be displayed. If /ADDRESS is used, no ident may
be specified.
/ALL
Specifies that detailed information on each entity is to be displayed.
By default, only a brief summary of each entity is given, except when a
specific table is displayed.
/CHILDREN
Specifies that all the child namespace structures for a specified
namespace entry are to be displayed. /CHILDREN cannot be used with
/TABLES.
/NAMESPACE
Specifies that ACPI namespace structures are to be displayed. Either
/NAMESPACE or /TABLES must be specified.

SHOW ADDRESS
Displays the page table related information about a memory address.
Format
SHOW ADDRESS address [/PHYSICAL]
Parameter
address
The requested address.
Qualifier
/PHYSICAL
Indicates that a physical address has been given. The SHOW ADDRESS
command displays the virtual address that maps to the given physical
address.
Description
The SHOW ADDRESS command displays the region of memory that contains
the memory address. It also shows all the page table entries (PTEs)
that map the page and can show the range of addresses mapped by the
given address if it is the address of a PTE. If the virtual address is
in physical memory, the corresponding physical address is displayed.
When the /PHYSICAL qualifier is given, the SHOW ADDRESS command
displays the virtual address that maps to the given physical address.
This provides you with a way to use SDA commands that do not have a
/PHYSICAL qualifier when only the physical address of a memory location
is known.
Examples
| #1 |
SDA> SHOW ADDRESS 80000000
FFFFFFFF.80000000 is an S0/S1 address
Mapped by Level-3 PTE at: FFFFFFFD.FFE00000

SDA> SHOW ADDRESS/PHYSICAL 029A6000
Physical address 00000000.029A6000 is mapped to process-space address 00000000.00030000
(process index 0024)
|
The SHOW ADDRESS command in this example shows physical address
00000000.029A6000 mapped to process-space address 00000000.00030000
(process index 0024).
SHOW BUGCHECK
Displays the value, name, and text associated with one or all bugcheck
codes.
Format
SHOW BUGCHECK {/ALL (d) | name | number}
Parameters
name
The name of the requested bugcheck code.
number
The value of the requested bugcheck code. The severity bits in the
value are ignored.
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 104
0100 DIRENTRY ACP failed to find same directory entry
|
The SHOW BUGCHECK command in this example shows the requested bugcheck
by number, ignoring the severity (FATAL).
| #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.

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]
| /EXCEPTION_FRAME =
intstk-address
| /NEXT_FRAME | /SUMMARY | /ALL}
Parameter
starting-address
For Alpha, an expression representing the starting address of the
procedure call frame to be displayed. If no starting-address is given,
the default starting address is the contents of the frame pointer (FP)
register of the SDA current process. For a process that uses pthreads,
the following SDA command can be used to display the starting addresses
for all pthreads:
For Integrity servers, the starting address is an expression
representing one of the following:
- The invocation context handle of a frame.
- The address of an exception frame. This is equivalent to the
following SDA command:
SDA> SHOW CALL_FRAME /EXCEPTION_FRAME=intstk-address
|
- The address of a Thread Environment Block (TEB).
For a list of
all TEBs for the process, use the following SDA command:
If no starting address is given, the default starting address is the
invocation context handle of the current procedure in the SDA current
process.
Qualifiers
/ALL
Displays details of all call frames beginning at the current frame and
continuing until bottom of stack (equivalent to SHOW CALL and repeated
execution of a SHOW CALL/NEXT command).
/EXCEPTION_FRAME=intstk-address
(Integrity servers only) Provides an alternate starting address for
SHOW CALL_FRAME. intstk-address is the address of an exception
frame from which SDA creates an initial invocation context and displays
the procedure call frame.
/NEXT_FRAME
Displays the procedure call frame starting at the address stored in the
frame 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_FRAME qualifier to the command.
/SUMMARY
Provides a one-line summary for each call frame, including exception
frames, system-service entry frames, ASTs, KPBs, and so on, until
reaching the bottom of the stack.
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_FRAME qualifier, or the address
contained in the SDA current process frame register (the default
action).
When using the SHOW CALL_FRAME/NEXT_FRAME command to follow a chain of
call frames, SDA signals the end of the chain by the following message:
Cannot display further call frames (bottom of stack)
|
This message indicates that the saved frame in the previous call frame
has a zero value (for Alpha) or that the current frame is marked Bottom
of Stack (for Integrity servers).

SHOW CLUSTER
Displays connection manager and system communications services (SCS)
information for all nodes in a cluster.
Format
SHOW CLUSTER { [{/ADDRESS=n | /CIRCUIT=pb-addr |
/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
/CIRCUIT=pb-addr, /CSID=csid, and /NODE=name
qualifiers.
/CIRCUIT=pb-addr
Displays only the OpenVMS Cluster system information for a specific
path, where pb-addr is the address of its path block. This
qualifier is mutually exclusive with the /ADDRESS=n,
/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,
/CIRCUIT=pb-addr, 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, /CIRCUIT=pb-addr, 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.
If the qualifier /CIRCUIT=pb-addr is specified, the SHOW
CLUSTER command displays only the information from the specified path
block.

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.
