1 /ADDRESS
/ADDRESS=PFN-entry-address Displays the PFN database entry at the address specified. The address specified is rounded to the nearest entry address, so if you have an address that points to one of the fields of the entry, the correct database entry will still be found.
2 /ALL
Displays the following lists: Free page list Zeroed free page list Modified page list Bad page list Untested page list Private page lists, if any Per-color or per-RAD free and zeroed free page lists Entire database in order by page frame number This is the default behavior of the SHOW PFN_DATA command. SDA precedes each list with a count of the pages it contains and its low and high limits.
3 /BAD
Displays the bad page list. SDA precedes the list with a count of the pages it contains, its low limit, and its high limit.
4 /COLOR
/COLOR [= {n|ALL} ] Displays data on page coloring. The following table shows the command options available with the COLOR and RAD qualifiers, which are functionally equivalent. Options Meaning /COLOR with no Displays a summary of the lengths of the color value page lists for both free pages and zeroed pages. /COLOR=n where n Displays the data in the PFN lists (for the is a color number specified color) for both free and zeroed pages. /COLOR=ALL Displays the data in the PFN lists (for all colors), for both free and zeroed free pages. /COLOR=n or Displays only the data in the PFN list (for /COLOR=ALL with the specified color or all colors), for either /FREE or /ZERO free or zeroed free pages as appropriate. The qualifiers /BAD and /MODIFIED are ignored with /COLOR=n and /COLOR=ALL. /COLOR without an Displays the color summary in addition to the option specified display of the requested list. together with one or more of /FREE, /ZERO, /BAD, or /MODIFIED For more information on page coloring, see OpenVMS System Management Utilities Reference Manual: M-Z.
5 /FREE
Displays the free page list. SDA precedes the list with a count of the pages it contains, its low limit, and its high limit.
6 /MAP
Displays the contents of the PFN memory map. On platforms that support it, the I/O space map is also displayed. You cannot combine the /MAP qualifier with any parameters or other qualifiers.
7 /MODIFIED
Displays the modified page list. SDA precedes the list with a count of the pages it contains, its low limit, and its high limit.
8 /PRIVATE
/PRIVATE [=address] Displays private PFN lists. If no address is given, all private PFN lists are displayed; if an address is given, only the PFN list whose head is at the given address is displayed.
9 /RAD
/RAD [= {n|ALL} ] Displays data on the disposition of pages among the Resource Affinity Domains (RADs) on applicable systems. /RAD is functionally equivalent to /COLOR. See the table in the /COLOR qualifier description for the command options available with /RAD.
10 /SUMMARY
/SUMMARY[=(option,...)] By default, displays a summary of all pages in the system, totaling pages by page location (Free List, Modified List, Active, and so on) and by page type (Process, System, Global, and so on).

If multiple options are given, they must be separated by commas and enclosed in parentheses. Available options are: o /SUMMARY=PROCESS Displays a breakdown of active process pages for each process by virtual address (P0, P1, and so on), and of non-active process pages by page location. o /SUMMARY=GLOBAL Displays a breakdown for each global section of its in-memory pages by page location. o /SUMMARY=RAD If RADs are enabled on the system, displays a breakdown for each RAD of its in-memory pages by location and type. o /SUMMARY=ALL Equivalent to /SUMMARY=(PROCESS,GLOBAL,RAD) You cannot combine the /SUMMARY qualifier with any other qualifiers, but you can specify a range.
11 /SYSTEM
Displays the entire PFN database in order by page frame number, starting at PFN 0000.
12 /UNTESTED
Displays the state of the untested PFN list that was set up for deferred memory testing.
