SHOW PAGE_TABLE
SHOW PAGE_TABLE
Displays a range of system page table entries, the entire system page table, or
the entire global page table.
Format
SHOW PAGE_TABLE [/qualifier[,...]] [range]
Parameter
range
Range of virtual addresses for which SDA is to display page table entries. You
can express a range using the following format:
m:n Range of virtual addresses from m to n
m;n Range of virtual addresses starting at m and continuing for n bytes
Qualifiers
/GLOBAL
Lists the global page table.
/SYSTEM
Lists the system page table.
/ALL
Lists both the global and system page tables. This is the default behavior of
SHOW PAGE_TABLE.
Description
For each virtual address displayed by the SHOW PAGE_TABLE command,
the first six columns of the listing provide the associated page table entry and
describe its location, characteristics, and contents (see Table SDA–16). SDA
obtains this information from the system page table.
If the virtual page has been mapped to a physical page, the last nine columns of
the listing include information from the page frame number (PFN) database (see
Table SDA–17). Otherwise, the section is left blank.
SDA indicates pages are inaccessible by displaying the following message:
-------- n NULL PAGES
Here, n indicates the number of inaccessible pages.
