SHOW LAN

Displays information contained in various local area network (LAN) data structures. The default qualifiers are /CSMACD/FDDI.

Format

SHOW LAN [/qualifier[,...]]

Parameters

None.

Qualifiers

/CLIENT=xx
Specifies that information be displayed for the specified client. Valid client designators are SCA, DECNET, LAT, MOPRC, TCPIP, DIAG, ELN, BIOS, LAST, USER, ARP, MOPDL, LOOP, BRIDGE, DNAME, ENCRY, DTIME, and LTM. /CLIENT, /DEVICE, and /UNIT are synonymous and mutually exclusive; each must be the last qualifier stated on an SDA command line.
/CLUEXIT
Specifies that cluster protocol information be displayed.
/COUNTERS
Specifies that the LAN station block (LSB) and unit control block (UCB) counters be displayed.
/CSMACD
Specifies that Carrier Sense, Multiple Access with Collision Detect (CSMACD) information for the LAN be displayed.
/CSMACD/FDDI (default)
Displays both Ethernet and FDDI information.
/DEVICE=xx[dn]
Specifies that information be displayed for the specified device. Device designators are specified in the format xxdn, where xx is the type of device, d is the device letter, and n is the unit number. The device letter and unit number are optional. /CLIENT, /DEVICE, and /UNIT are synonymous and mutually exclusive; each must be the last qualifier stated on an SDA command line.
/ERRORS
Specifies that the LSB and UCB error counters be displayed.
/FDDI
Specifies that Fiber Distributed Data Interface (FDDI) controller information for the LAN be displayed.
/FULL
Specifies that all information from the LAN, LSB, and UCB data structures be displayed.
/SUMMARY
Specifies that only a summary of LAN information (a list of flags, LSBs, UCBs, and base addresses) be printed. This is the default.
/TIMESTAMPS
Specifies to print time information (start and stop times and error times) from the device and unit data structures. SDA displays the data in chronological order.
/UNIT=xx/[dn]
Specifies that information be displayed for the specified unit. Unit designators are specified in the format xx/[dn], where xx is the type of unit, d is the device letter, and n is the unit number. The device letter and unit number are optional. /CLIENT, /DEVICE, and /UNIT are synonymous and mutually exclusive; each must be the last qualifier stated on an SDA command line.

Description

The SHOW LAN command displays information contained in various local area network (LAN) data structures. By default, or when you specify the /SUMMARY qualifier, SHOW LAN displays a list of flags, LSBs, UCBs, and base addresses. When you specify the /FULL qualifier, SHOW LAN displays all information found in the LAN, LSB, and UCB data structures.

The SHOW LAN command displays LAN timestamp information.

SHOW LOCK

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

Format

SHOW LOCK {lock-id|/ALL|/CACHED|/NAME=resource-name}

Parameters

lock-id
Name of a specific lock. You cannot specify both a lock-id and a resource-name in the same command line.

Qualifiers

/ALL
Lists all locks that exist in the system. This is the default behavior of the SHOW LOCK command.
/CACHED
Shows only cached lock blocks (LKBs).
/NAME=resource-name
Displays information about the resource associated with the lock whose resource name begins with the specified resource-name. For case-sensitive names, enclose the resource-name in quotation marks. You cannot specify both a lock-id and resource-name in the same command line.

Description

The SHOW LOCK command displays the information described in Table SDA-15 for each lock management lock in the system or for the lock indicated by lock-id. (Use the SHOW SPINLOCK 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 System Services Reference Manual for additional discussion of the significance of this information.
You can display information about the resource to which a lock is queued by issuing the SHOW RESOURCE command and specifying the lock-id of the resource.

Table SDA-15 Contents of the SHOW LOCK and SHOW PROCESS/LOCKS Displays
Display Element Description

Process Index ¹ Index into 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.

--- Processor access mode of the name space in which the resource block (RSB) associated with the lock resides.

--- 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.

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