SHOW PROCESS
Column Contents
STATUS Three columns that list the following status information:
• Page type
• Location of the page in physical memory
• Indication of whether the page is locked into the working set
When SDA locates one or more unused working set entries, it issues the following
message:
--- n empty entries
In this message, n is the number (in decimal) of contiguous, unused entries.
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 the first free entry and
last used entry.
SDA displays the information listed in Table SDA–19 for each PST entry.

Display
Part Definition
INDEX Offset into the PST at which the entry is found. Because entries
in the process section table begin at the highest location in
the table, and the table expands toward lower addresses, the
following expression determines the address of an entry in the
table: PHD + PSTBASOFF—INDEX.
ADDRESS Virtual address that marks the beginning of the first page of the
section described by this entry.
PAGES Length, in pages, of the process section.
VBN Virtual block number, the number of the file’s virtual block that
is mapped into the section’s first page.
CLUSTER Cluster size used when faulting pages into this process section.
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 and P1 page table displays, also produced by the /PAGE_
TABLES qualifier, display listings of the page table entries of the process in the
same format as that produced by the SHOW PAGE_TABLE command (see Tables
SDA–16 and SDA–17).
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.
