The SHOW PROCESS/ALL command displays information taken from the software PCB of process GLOBE, and then proceeds to display the process header, the registers of the process, the process section table, the P0 page table, the P1 page table, and information about the I/O channels owned by the process. You can also obtain these displays by using the /PCB, /PHD, /REGISTERS, /PROCESS_SECTION_TABLE, /P0, /P1, and /CHANNEL qualifiers, respectively.

The SHOW PROCESS/LOCKS/INDEX=0A command displays information about the locks held by process JOB_CONTROL, whose PCB is at index 0A, into the system's PCB list. This command implicitly makes JOB_CONTROL the SDA current process for subsequent commands that display process context information. It has no effect on SDA CPU context because JOB_CONTROL is not current on any processor in the multiprocessing system.

SDA> SHOW PROCESS/TRANSACTIONS=(DISPLAY=THREADS, 
   TID=FAC21DE2-BA88-0092-8FA6-B24B)
 
      

The SHOW PROCESS command displays the transaction thread information for the transaction whose identifier is FAC21DE2-BA88-0092-8FA6-B24B.

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

Format

SHOW RESOURCE {/ALL|/LOCKID=lock-id|/NAME=resource-name}

Parameters

None.

Qualifiers

/ALL

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

/LOCKID=lock-id

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

/NAME=resource-name

Displays information about the resource whose resource name begins with the specified resource-name. For case-sensitive names, enclose resource-name in quotation marks.

Description

The SHOW RESOURCE command displays the information listed in Table SDA-21 for each resource in the system or for the specific resource associated with the specified lock-id.

Table SDA-21 Resource Information in the SHOW RESOURCE Display

Field	Contents
Address of RSB	Address of the resource block (RSB) that describes this resource.
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.
Sub-RSB count	Number of RSBs of which this RSB is the parent. This field is 0 if the RSB has no sub-RSBs.
Group grant mode	Indication of the most restrictive mode in which a lock on this resource has been granted. This field can contain the following values (shown in order from the least restrictive mode to the most restrictive): NL Null mode CR Concurrent-read mode CW Concurrent-write mode PR Protected-read mode PW Protected-write mode EX Exclusive mode For information about conflicting and incompatible lock modes, see the OpenVMS System Services Reference Manual.
Conversion grant mode	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.
BLKAST count	Number of locks on this resource that have requested a blocking AST.
Value block	Hexadecimal dump of the 16-byte block value block associated with this resource.
Sequence #	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.
CSID	Cluster system identification number (CSID) 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.
Length	Length in bytes of the resource name.
---	Processor mode of the name space in which this RSB resides.
---	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.
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.

The SHOW RESOURCE command displays information taken from the RSBs of all resources in the system. For instance, the RSB at 807EB9E0₁₆ is a parent block with no sub-RSBs. The most restrictive lock granted on this resource is in protected-write (PW) mode. There is a lock on the conversion queue waiting to be converted from PW mode to exclusive (EX) mode.

The SHOW PROCESS/LOCKS command lists all locks associated with the SDA current process, STARTQ. Its display is identical to that of the SHOW LOCK command, illustrated in Table SDA-15. The SHOW RESOURCE/LOCKID=117054F command determines that this particular lock is on the granted queue in protected-write mode for the resource at 806BB050₁₆.
