Detailed report

Edit online

The detailed report (-D) displays information about the pages owned by a segment and, on-demand, it can display the frames these pages are mapped to. To print the detailed report, specify the -D flag.

Several fields are presented before the listing of the pages used:

Segid
The segment identifier.
Type
The type of the segment.
PSize
The type of the segment.
Address Range
Ranges in which frames are used by this segment.

Ranges in which frames are used by this segment.

Size of paging space allocation
Virtual
Number of pages used by this segment.
Inuse
Number of frames used by this segment.

Column headings in a detailed report:

Page
Relative page number to the virtual space. This page number can be higher than the number of frames in a segment (65535) if the virtual space is larger than a single segment (large file).
Frame
Frame number in the real memory. Since frames are always considered 4KB in size regardless of the page size of the segment, for any page size larger than 4 KB, a range of frames instead of a single frame is associated to one page. This range is noted as XXXXXXX..YYYYYYY, which means that the continuous range of frames between ID XXXXXXX and YYYYYYY is used for the given page.
Pin
Indicates if the frame is pinned or not.
Ref
Indicates if the frame has been referenced by a process.
Mod
Indicates if the frame has been modified by a process.
ExtSegid
Extended segment identifier. This field is only set when the page number is higher than the maximum number of frames in a segment.
ExtPage
Extended page number. This field is only set when the page number is higher than the maximum number of frames in a segment and indicates the page number within the extended segment.
Note:
  • The -@ flag has no effect on the -D option.
  • This option only supports the additional -O frame option, which shows additional frame level details.
  • The format used by this report is on 160 columns.
