SHOW RSPID

Displays information about response IDs (RSPIDs) of all System Communications Services (SCS) connections or, optionally, about a specific SCS connection.

Format

SHOW RSPID [/CONNECTION=cdt-address ]

Parameters

None.

Qualifier

/CONNECTION=cdt-address
Displays RSPID information for the specific SCS connection whose connection descriptor table (CDT) address is provided in cdt-address. You can find the cdt-address for any active connection on the system in the CDT summary page display of the SHOW CONNECTIONS command. CDT addresses are also stored in many individual data structures related to SCS connections. These data structures include class driver request packets (CDRPs) and unit control blocks (UCBs) for class drivers that use SCS and cluster system blocks (CSBs) for the connection manager.

Description

Whenever a local system application (SYSAP) requires a response from a remote SYSAP, a unique number, called an RSPID, is assigned to the response by the local system. The RSPID is transmitted in the original request (as a means of identification), and the remote SYSAP returns the same RSPID in its response to the original request.
The SHOW RSPID command displays information taken from the response descriptor table (RDT), which lists the currently open local requests that require responses from SYSAPs at a remote node. For each RSPID, SDA displays the following information:

RSPID value
Address of the class driver request packet (CDRP), which generally represents the original request
Address of the CDT that is using the RSPID
Name of the local process using the RSPID
Remote node from which a response is required (and has not yet been received)

SHOW SHM_CPP

Displays information about the shared memory common property partitions (CPPs). The default display shows a single-page summary that includes a single line for each CPP.

Format

SHOW SHM_CPP [/ QUALIFIERS]

Parameters

None.

Qualifiers

/ADDRESS=n
Displays a detailed page of information about an individual shared memory CPP given the address of the SHM_CPP structure.
/ALL
Displays a detailed page of information about each shared memory CPP.
/IDENT=n
Displays a detailed page of information about an individual shared memory CPP.
/PFN [=option]
Displays PFN data in addition to the basic SHM_CPP. The default is all lists (free, bad, untested), plus the PFN database pages and the complete range of PFNs in the CPP.
To display only the complete range of PFNs in the CPP, use the keyword ALL_FRAGMENTS with the /PFN qualifier:
/PFN = ALL_FRAGMENTS
To display only the bad page list, use the keyword BAD with the /PFN qualifier:
/PFN = BAD
To display only the free page list, use the keyword FREE with the /PFN qualifier:
/PFN = FREE
To display the PFNs containing the PFN database, use the keyword PFNDB with the /PFN qualifier:
/PFN = PFNDB
To display only the untested page list, use the keyword UNTESTED with the /PFN qualifier:
/PFN = UNTESTED
To display multiple lists, you can combine keywords with the /PFN qualifier:
/PFN = (x,y)
If you specify /PFN without /ALL, /IDENT, or /ADDRESS, then the system displays the PFN lists from the last shared memory CPP accessed.

SHOW SPINLOCKS

Displays the multiprocessing synchronization data structures.

Format

SHOW SPINLOCKS {[name]|/ADDRESS=expression|/INDEX=expression} [/COUNTS|/OWNED|/DYNAMIC|/STATIC
|/PCB|/PORT|/CACHED_PCB|/MAILBOX] [{/BRIEF|/FULL}]

Parameter

name
Name of the spinlock to be displayed. Device spinlock names are of the form node$lock, where node indicates the OpenVMS Cluster node name and lock indicates the device and controller identification (for example, HAETAR$DUA). If there is no OpenVMS Cluster node name, the dollar sign ($) is also skipped (for example, DUA). This parameter cannot be used to identify mailbox, PCB, or cached PCB spinlocks.

Qualifiers

/ADDRESS=expression
Displays the spinlock at the address specified in expression. You can use the /ADDRESS qualifier to display a specific device, mailbox, PCB, or cached PCB spinlock; however, the name of the spinlock is listed as "Unknown" in the display.
/BRIEF
Produces a condensed display of the spinlock information displayed by default by the SHOW SPINLOCKS command, including the following: address, spinlock name or device name, IPL or device IPL, rank, ownership depth, and CPU ID of the owner CPU. If the system under analysis was executing with full-checking multiprocessing enabled (according to the setting of the MULTIPROCESSING or SYSTEM_CHECK system parameter), then the number of waiting CPUs and interlock status are also displayed.
/CACHED_PCB
Displays all PCB-specific spinlocks associated with PCBs of deleted processes.
/COUNTS
Produces a display of Spin, Wait, and Acquire counts for each spinlock (only if full-checking multiprocessing is enabled).
/DYNAMIC
Displays information for all dynamic spinlocks in the system (device, port, mailbox, PCB, and cached PCB spinlocks).
/FULL
Displays full descriptive and diagnostic information for each displayed spinlock.
/INDEX=expression
Displays the static spinlock whose index is specified in expression. You can only use the /INDEX qualifier to display a named static spinlock.
/MAILBOX
Displays all mailbox-specific spinlocks.
/OWNED
Displays information for all spinlocks owned by a CPU. If no processors own any spinlocks, SDA displays the following message:
%SDA-I-NOSPLOWNED, all requested spinlocks are unowned
/PCB
Displays all PCB-specific spinlocks.
/PORT
Displays all port spinlocks.
/STATIC
Displays information for all static spinlocks in the system.

Description

The SHOW SPINLOCKS command displays status and diagnostic information about the multiprocessing synchronization structures known as spinlocks.
A static spinlock is a spinlock whose data structure is permanently assembled into the system. Static spinlocks are accessed as indexes into a vector of longword addresses called the spinlock vector, the address of which is contained in SMP$AR_SPNLKVEC. Table 4-28 lists the static spinlocks.
A dynamic spinlock is a spinlock that is created based on the configuration of a particular system. One such dynamic spinlock is the device lock SYSMAN creates when configuring a particular device. This device lock synchronizes access to the device's registers and certain UCB fields. The system creates a dynamic spinlock by allocating space from nonpaged pool, rather than assembling the lock into the system as it does in creating a static spinlock. Other types of dynamic spinlocks are: port spinlocks, mailbox spinlocks, PCB and cached PCB spinlocks.
See the Writing OpenVMS Alpha Device Drivers in C for a full discussion of the role of spinlocks in maintaining synchronization of kernel-mode activities in a multiprocessing environment.

PERFMON Spinlock for I/O performance monitoring

INVALIDATE Spinlock for system space translation buffer (TB) invalidation

HWCLK Spinlock on hardware clock database, including the quadword containing the due time of the first timer queue entry (EXE$GQ_1ST_TIME) and the quadword containing the system time (EXE$GQ_SYSTIME)

MEGA Spinlock for serializing access to fork-wait queue

EMB/MCHECK Spinlock for allocating and releasing error-logging buffers and synchronizing certain machine error handling

For each spinlock in the system, SHOW SPINLOCKS provides the following information:

Name of the spinlock (or device name for the device lock)
Address of the spinlock data structure (SPL)
The owning CPU's CPU ID
IPL at which allocation of the lock is synchronized on a local processor
Number of nested acquisitions of the spinlock by the processor owning the spinlock (Ownership Depth)
Rank of the spinlock
Timeout interval for spinlock acquisition (in terms of 10 milliseconds)
Shared array (shared spinlock context block pointer)
Number of processors waiting to obtain the spinlock
Interlock (synchronization mutex used when full-checking multiprocessing is enabled)

The last two items (CPUs waiting and Interlock) are only displayed if full-checking multiprocessing is enabled.
SHOW SPINLOCKS/BRIEF produces a condensed display of this same information, excluding the share array and timeout interval.
SHOW SPINLOCKS/COUNTS displays only the Spin, Wait, and Acquire counts for each spinlock.
If the system under analysis was executing with full-checking multiprocessing enabled, SHOW SPINLOCKS/FULL adds to the spinlock display the Spin, Wait, and Acquire counts and the last sixteen PCs at which the lock was acquired or released. If applicable, SDA also displays the PC of the last release of multiple, nested acquisitions of the lock.
If no spinlock name, address, or index is given, then information is displayed for all applicable spinlocks.
