The SHOW LAN/ELAN/DEVICE=HCA command displays information for the ATM
device (HCA) driver only.
SHOW LOCKS
Displays information about all lock management locks in the system, or
about a specified lock.
Format
SHOW LOCKS {lock-id|/ADDRESS=n|/ALL (d)|
/BLOCKING|/BRIEF|/CACHED|/CONVERT|/GRANTED
|/NAME=name|/POOL|
/STATUS=(keyword
[,keyword...]) |/SUMMARY|
/WAITING}
Parameter
lock-id
Name of a specific lock.
Qualifiers
/ADDRESS=n
Displays a specific lock, given the address of the lock block.
/ALL
Lists all locks that exist in the system. This is the default behavior
of the SHOW LOCKS command.
/BLOCKING
Displays only the locks that have a blocking AST specified or attached.
/BRIEF
Displays a single line of information for each lock.
/CACHED
Displays locks that are no longer valid. The memory for these locks is
saved so that later requests for locks can use them. Cached locks are
not displayed in the other SHOW LOCKS commands.
/CONVERT
Displays only the locks that are on the conversion queue.
/GRANTED
Displays only the locks that are on the granted queue.
/NAME=name
Displays all locks on the specified resource. Name can be the
actual name of the resource, if it only contains uppercase letters,
numerals, the underscore (_), dollar sign, colon (:), and some other
printable characters, as for example, /NAME=MY_LOCK. If it contains
other printable characters (including lowercase letters), you may need
to enclose the name in quotation marks (""), as for example,
/NAME="My_Lock/47". If it contains nonprintable characters, you can
specify the name as a comma-separated list comprised of strings and
hexadecimal numbers. For example, /NAME=("My_Lock",0C00,"/47") would
specify the name "My_Lock<NUL><FF>/47". The hexadecimal
number can be no more than 8 digits (4 bytes) in length. Nonprintable
sequences of more than 4 bytes must be split into multiple hexadecimal
numbers. The maximum length of a resource name is 32 characters.
/POOL
Displays the lock manager's poolzone information, which contains the
lock blocks (LKB) and resource blocks (RSB).
/STATUS=(keyword[,keyword...])
Displays only the locks that have the specified status bits set in the
LKB$L_STATUS field. Status keywords are as follows:

Description
The SHOW LOCKS command displays the information described in
Table 4-6 for each lock management lock in the system, or for the
lock indicated by lock-id, an address or name. (Use
the SHOW SPINLOCKS command to display information about spinlocks.) You
can obtain a similar display for the locks owned by a specific process
by issuing the appropriate SHOW PROCESS/LOCKS command. See the
HP OpenVMS Programming Concepts Manual for additional information.
You can display information about the resource to which a lock is
queued by issuing the SHOW RESOURCES command specifying the resource's
lock-id.

This SDA session shows the output of the SHOW LOCKS command for several
locks. The SHOW RESOURCES command, executed for the last displayed
lock, verifies that the lock is in the resource's granted queue. (See
Table 4-25 for a full explanation of the contents of the display of
the SHOW RESOURCES command.)
SHOW MACHINE_CHECK
Displays the contents of the stored machine check frame. This command
is valid for the DEC 4000 Alpha, DEC 7000 Alpha, and DEC 10000 Alpha
computers only.
Format
SHOW MACHINE_CHECK [/FULL] [cpu-id]
Parameter
cpu-id
Numeric value from 00 to 1F16 indicating the identity of the
CPU for which context information is to be displayed. This parameter
changes the SDA current CPU (the default) to the CPU specified with
cpu-id. If you specify a value outside this range, or
you specify the cpu-id of a processor that was not
active at the time of the system failure, SDA displays the following
message:
%SDA-E-CPUNOTVLD, CPU not booted or CPU number out of range
|
If you use the cpu-id parameter, the SHOW
MACHINE_CHECK command performs an implicit SET CPU command, making the
CPU indicated by cpu-id the current CPU for subsequent
SDA commands. (See the description of the SET CPU command and
Section 2.5 for information on how this can affect the CPU
context---and process context---in which SDA commands execute.)
Qualifier
/FULL
Specifies that a detailed version of the machine check information be
displayed. This is currently identical to the default summary display.
Description
The SHOW MACHINE_CHECK command displays the contents of the stored
machine check frame. A separate frame is allocated at boot time for
every CPU in a multiple-CPU system. This command is valid for the DEC
4000 Alpha, DEC 7000 Alpha, and DEC 10000 Alpha computers only.
If you do not specify a qualifier, a summary version of the machine
check frame is displayed.
The default cpu-id is the SDA current CPU.
