The SHOW LAN/ELAN/DEVICE=HCA command displays information for the ATM device (HCA) driver only.

SHOW LOCK

Displays information about all lock management locks in the system, or about a specified lock.

Format

SHOW LOCK {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 LOCK command.
/BLOCKING
Displays only the locks that have a blocking AST specified or attached.
/BRIEF
Displays a brief one line of lock information.
/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Displays locks that are no longer valid.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 LOCK 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 a specified lock with the given name.
/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:

Keyword Meaning

ASYNC Completes request asynchronously

BLKASTFLG Specifies a blocking AST

BLKASTQED Indicates a blocking AST is queued

BRL Indicates a byte range lock

CACHED Indicates a lock block in cache

CVTSUBRNG Indicates a sub-range convert request

CVTTOSYS Converts back to system-owned lock

DBLKAST Delivers a blocking AST

DCPLAST Delivers a completion AST

FLOCK Indicates a fork lock

GRSUBRNG Grants sub-range lock

IP Indicates operation in process

MSTCPY Indicates a lock block is a master copy

NEWSUBRNG Indicates a new sub-range request

NOQUOTA Does not charge quota

PCACHED Indicates lock block needs to be cached

PROTECT Indicates a protected lock

RESEND Resends during failover

RM_RBRQD Requires remaster rebuild

RNGBLK Specifies a range block

RNGCHG Indicates a changing range

TIMOUTQ Indicates lock block is on timeout queue

VALBLKRD Indicates read access to lock value block

VALBLKWRT Indicates write access to lock value block

WASSYSOWN Indicates was system-owned lock

2PC_IP Indicates a two-phase operation in progress

2PC_PEND Indicates a two-phase operation pending

/SUMMARY
Displays summary data and performance counters.
/WAITING
Displays only the waiting locks.

Description

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

Table 4-4 Contents of the SHOW LOCK and SHOW PROCESS/LOCKS Displays
Display Element Description

Process Index ¹ Index in the PCB array to a pointer to the process control block (PCB) of the process that owns the lock.

Name ¹ Name of the process that owns the lock.

Extended PID ¹ Clusterwide identification of the process that owns the lock.

Lock ID Identification of the lock.

PID Systemwide identification of the lock.

Flags Information specified in the request for the lock.

Par. ID Identification of the lock's parent lock.

Granted at Lock mode at which the lock was granted.

Sublocks Identification numbers of the locks that the lock owns.

LKB Address of the lock block (LKB). If a blocking AST has been enabled for this lock, the notation "BLKAST" appears next to the LKB address.

Resource Dump of the resource name. The two leftmost columns of the dump show its contents as hexadecimal values, the least significant byte being represented by the rightmost two digits. The rightmost column represents its contents as ASCII text, the least significant byte being represented by the leftmost character.

Status Status of the lock, information used internally by the lock manager.

Length Length of the resource name.

Mode Processor access mode of the namespace in which the resource block (RSB) associated with the lock resides.

Owner Owner of the resource. Certain resources owned by the operating system list "System" as the owner. Resources owned by a group have the number (in octal) of the owning group in this field.

Copy Indication of whether the lock is mastered on the local system or is a process copy.

This SDA session shows the output of the SHOW LOCK command for several locks. The SHOW RESOURCE command, executed for the last displayed lock, verifies that the lock is in the resource's granted queue. (See Table 4-20 for a full explanation of the contents of the display of the SHOW RESOURCE 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 processor 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 processor indicated by cpu-id the current CPU for subsequent SDA commands. (See the description of the SET CPU command and Chapter 2, 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 no qualifier is specified, a summary version of the machine check frame is displayed.
The default cpu-id is the SDA current CPU.
