SHOW RESOURCES

Displays information about all resources in the system or about a resource associated with a specific lock.

Format

SHOW RESOURCES {/ADDRESS=n|/ALL (d)
| /BRIEF|/CACHED|/CONTENTION [=ALL] |/LOCKID=lock-id |/LIST|/NAME=name
|/OWNED|/STATUS= (keyword [,keyword...])}


Parameters

None.

Qualifiers

/ADDRESS=n

Displays information from the resource block at the specified address.

/ALL

Displays information from all resource blocks (RSBs) in the system. This is the default behavior of the SHOW RESOURCES command.

/BRIEF

Displays a single line of information for each resource.

/CACHED

Displays resource blocks that are no longer valid. The memory for these resources is saved so that later requests for resources can use them.

/CONTENTION [=ALL]

Displays only resources that have at least one lock on either the waiting or conversion queue. Unless you specify the ALL keyword, resources with locks on the waiting or conversion queues that are not participating in deadlock searches are ignored. (Locks not participating in deadlock searches are requested with either the LCK$M_NODLCKWT or LCK$M_NODLCKBLK flags.)

/LIST

Displays summary information for each resource, followed by a list of all locks associated with the resource.

/LOCKID=lock-id

Displays information on the resource associated with the lock with the specified lock-id.

/NAME=name

Displays information about the specific resource. Name may 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, the name may be specified as a comma-separated list comprised of strings and hexadecimal numbers, as 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 or more than 4 bytes must be split into multiple hexadecimal numbers. The maximum length of a resource name is 32 characters.

/OWNED

Displays only owned resources.

/STATUS=(keyword [,keyword...])

Displays only resources that have the specified status bits set in the RSB$L_STATUS field. Status keywords are as follows:
Keyword Meaning
2PC_IP Indicates a two-phase convert operation in progress
BRL Indicates byte range resource
CHK_BTR Checks for better master
CVTFULRNG Indicates full-range requests in convert queue
CVTSUBRNG Indicates sub-range requests in convert queue
DIRENTRY Indicates directory entry during failover
DIR_IP Creates directory entry
DIR_RQD Indicates directory entry required
INVPEND Checks for value block invalidation
RBLD_ACT Indicates lock rebuild active for this tree
RBLD_IP Indicates rebuild operation in progress
RBLD_RQD Indicates rebuild required for this resource tree
RM_ACCEPT Accepts new master
RM_DEFLECT Deflects remote interest
RM_IP Indicates resource remaster in progress
RM_PEND Indicates a pending resource remaster operation
RM_RBLD Indicates to always rebuild resource tree
RM_WAIT Blocks local activity
VALCUR Indicates value block is current
VALINVLD Indicates value block invalid
WTFULRNG Indicates full-range requests in wait queue
WTSUBRNG Indicates a sub-range requests in wait queue

Description

The SHOW RESOURCES command displays the information listed in Table 4-25 either for each resource in the system or for the specific resource associated with the specified lock-id, address, or name.

Table 4-25 Resource Information in the SHOW RESOURCES Display
Field (in order of display) Contents
RSB Address of the resource block (RSB) that describes this resource.
GGMODE Indication of the most restrictive mode in which a lock on this resource has been granted. Table 4-26 shows the values and their meanings.

For information on conflicting and incompatible lock modes, see the HP OpenVMS System Services Reference Manual.

Status The contents of the resource block status field.
Parent RSB Address of the RSB that is the parent of this RSB. This field is 00000000 if the RSB itself is a parent block.
CGMODE Indication of the most restrictive lock mode to which a lock on this resource is waiting to be converted. This does not include the mode for which the lock at the head of the conversion queue is waiting. See Table 4-26.
Sub-RSB count Number of RSBs of which this RSB is the parent. This field is 0 if the RSB has no sub-RSBs.
FGMODE Indication of the full-range grant mode. See Table 4-26.
Lock Count The total count of all locks on the resource.
RQSEQNM Sequence number of the request.
BLKAST count Number of locks on this resource that have requested a blocking AST.
CSID Cluster system identification number (CSID) and name of the node that owns the resource.
Resource Dump of the name of this resource, as stored at the end of the RSB. The first two columns are the hexadecimal representation of the name, with the least significant byte represented by the rightmost two digits in the rightmost column. The third column contains the ASCII representation of the name, the least significant byte being represented by the leftmost character in the column. Periods in this column represent values that correspond to nonprinting ASCII characters.
Valblk Valblk hexadecimal and ASCII dump of the first 16 bytes of the value block associated with this resource. See Extended Value Block later in this table for the display of the rest of the value block.
Length Length in bytes of the resource name.
x mode Processor mode of the namespace in which this RSB resides (Group, Kernel, User).
owner Owner of the resource. Certain resources, owned by the operating system, list "System" as the owner. Locks owned by a group have the number (in octal) of the owning group in this field.
Seqnum Sequence number associated with the resource's value block. If the number indicates that the value block is not valid, the words "Not valid" appear to the right of the number.
Extended Valblk If any of the last 48 bytes of the value block (see Valblk earlier in this table) are non-zero, then the entire 64-byte value block is displayed as hexadecimal and ASCII dumps. Otherwise this display is omitted. The display appears only when value block contents are non-zero, without regard to the state of the RSB$M_XVAL_VALID flag.
Granted queue List of locks on this resource that have been granted. For each lock in the list, SDA displays the number of the lock and the lock mode in which the lock was granted.
Conversion queue List of locks waiting to be converted from one mode to another. For each lock in the list, SDA displays the number of the lock, the mode in which the lock was granted, and the mode to which the lock is to be converted.
Waiting queue List of locks waiting to be granted. For each lock in the list, SDA displays the number of the lock and the mode requested for that lock.

Table 4-26 Lock Modes on Resources
Value1 Meaning
NL Null mode
CR Concurrent-read mode
CW Concurrent-write mode
PR Protected-read mode
PW Protected-write mode
EX Exclusive mode


1Values are shown in order from the least restrictive mode to the most restrictive.
