When SDA locates one or more unused working set entries, or entries that do not match the specified option, it issues the following message:
--- n entries not displayedIn this message, n is the number (in decimal) of contiguous entries not displayed.
The process section table information and process section table displays, also produced by the /PROCESS_SECTION_TABLE qualifier, list each entry in the process section table (PST) and display the offsets to, and the indices of, the first free entry and last used entry.
SDA displays the information listed in Table SDA-26 for each PST entry.
| Part | Definition |
|---|---|
| INDEX | Index number of the entry. Entries in the process section table begin at the highest location in the table, and the table expands toward lower addresses. |
| ADDRESS | Address of the process section table entry. |
| SECTION ADDRESS | Virtual address that marks the beginning of the first page of the section described by this entry. |
| PAGELETS | Length of the process section. This is in units of pagelets, except for a PFN-mapped section in which the units are pages. |
| WINDOW | Address of the window control block on which the section file is open. |
| VBN | Virtual block number. The number of the file's virtual block that is mapped into the section's first page. |
| CCB | Address of the channel control block on which the section file is open. |
| REFCNT | Number of pages of this section that are currently mapped. |
| FLINK | Forward link. The pointer to the next entry in the PST list. |
| BLINK | Backward link. The pointer to the previous entry in the PST list. |
| FLAGS | Flags that describe the access that processes have to the process section. |
The P0 page table, P1 page table, and P2 page table displays, also produced by the /PAGE_TABLES qualifier, display listings of the process page table entries in the same format as that produced by the SHOW PAGE_TABLE command (see Tables SDA-13 through Table SDA-18.)
The process active channels display, the last produced by SHOW PROCESS/ALL and the only one produced by the /CHANNEL qualifier, displays the following information for each I/O channel assigned to the process:
| Column | Contents |
|---|---|
| Channel | Number of the channel |
| Window | Address of the window control block (WCB) for the file if the device is a file-oriented device; zero otherwise |
| Status | Status of the device: "Busy" if the device has an I/O operation outstanding; blank otherwise |
| Device/file accessed | Name of the device and, if applicable, name of the file being accessed on that device |
The information listed under the heading "Device/file accessed" varies from channel to channel and from process to process. SDA displays certain information according to the conditions listed in Table SDA-27.
| Information Displayed¹ | Type of Process |
|---|---|
| dcuu: | SDA displays this information for devices that are not file structured, such as terminals, and for processes that do not open files in the normal way. |
| dcuu: filespec | SDA displays this information only if you are examining a running system, and only if your process has enough privilege to translate the file-id into the filespec. |
| dcuu:( file-id) filespec | SDA displays this information only when you are examining a dump. The filespec corresponds to the file-id on the device listed. If you are examining a dump from your own system, the filespec is probably valid. If you are examining a dump from another system, the filespec is probably meaningless in the context of your system. |
| dcuu:( file-id) | The file-id no longer points to a valid filespec, as when you look at a dump from another system; or the process in which you are running SDA does not have enough privilege to translate the file-id into the corresponding filespec. |
| section file | Indicates that the file in question is mapped into the processes' memory. |

The SHOW PROCESS/ALL command displays information taken from the PCB of process VERIFICATION, and then proceeds to display the process header, the process registers, the process section table, the page tables of the process, images activated, and information about the I/O channels owned by the process. These displays may also be obtained by the /PCB, /PHD, /REGISTERS, /RDE, /PROCESS_SECTION_TABLE, /P0, /P1, /P2, /PT, /IMAGES, and /CHANNEL qualifiers, respectively.
This example displays the page tables of a process whose PCB address is 805E7980.

The SHOW PROCESS/IMAGES command displays the address of the image control block; the start and end addresses of the image; the activation code; the protected and shareable flags; the image name; the major and minor IDs of the image; and the base, end, image offset, and section type for installed resident images.
Displays information about all resources in the system, or about a resource associated with a specific lock.
SHOW RESOURCE {/ADDRESS=n|/ALL (d)|/CACHED
| /LOCKID=lock-id|/NAME=resource-name}
None.
/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 RESOURCE command./CACHED
Displays resource blocks that are no longer valid. The memory for these resources is kept around so that later requests for resources can use them./LOCKID=lock-id
Displays information on the resource associated with the lock with the specified lock-id./NAME=resource-name
Displays information about a specific resource.
The SHOW RESOURCE command displays the information listed in Table SDA-28 for each resource in the system or for the specific resource associated with the specified lock-id.
Table SDA-28 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. Lock Count The total count of all locks on the resource. BLKAST count Number of locks on this resource that have requested a blocking AST. GGMODE Indication of the most restrictive mode in which a lock on this resource has been granted. Table SDA-29 shows the fields and values and their meanings. They are shown in order from the least restrictive mode to the most restrictive. For information on conflicting and incompatible lock modes, see the OpenVMS System Services Reference Manual.
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. FGMODE Indication of the full-range grant mode. CSID Cluster system identification number (CSID) and name of the node that owns the resource. RQSEQNM Sequence number of the request. Status The contents of the resource block status field. 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 Hexadecimal dump of the 16-byte block value block associated with this resource. 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. 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. Length Length in bytes of the resource name. Mode Processor mode of the namespace in which this RSB resides. 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.
