RSMDATA HIGHVIRTUAL subcommand output

The RSM high virtual page report provides information about virtual pages above 2 gigabytes in the system, including page owner, location, and status. It also includes a summary of the memory objects.

The total number of pages in each page state are displayed for each job name at the end of the report. The report is sorted by the ASID of the job name and, within each ASID, by virtual page address. The memory objects are summarized after the detailed page report and before the totals, and they are sorted by the starting virtual page address.

The numbers in the top section of the report are hexadecimal. The totals at the bottom of the report are decimal.

The fields in the diagnostic data are as follows:

JOBNAME

The job name of the page owner.

Note: When the virtual page is high virtual common, HVCOMM appears instead of the job name.

PAGE

The virtual address for the page.

G

An indication of whether the page has been GETSTORed

Y: The page is GETSTORed.
N: The page is not GETSTORed.
S: The page is shared by this address space.

K

The storage protect key for the page.

F

An indication of whether the page is protected:

Y: The page is fetch-protected.
N: The page is not fetch-protected.

P

An indication of how the page is protected:

Y: The page is page-protected.
N: The page is not page-protected.

L

An indication of whether the page is locked:

Y: The page is locked
N: The page is not locked

STAT

The status of the page. Swap states apply only to working set pages.

DASD: Page resides on a paging data set.
FREF: First reference state. The page was never referenced or it was released by a DETACH request.
FRFM: First reference state. The 1M page was never referenced or it was released by a DETACH request.
GUARD: Page resides in the guarded area of the memory object.
HIDE: Page is hidden.
REAL: Page resides in real storage. It is either valid or has output paging I/O in progress.
RL_M: 1 MB page resides in a real frame. It is either valid or has output paging I/O in progress.
RL2G: 2 GB page resides in a real frame.
SCM: Page resides on storage-class memory (SCM).
SCMM: 1M page resides on storage-class memory (SCM).
SIAI: Swap-in from auxiliary storage in progress.
SOAI: Swap-out to auxiliary storage in progress.
SWAX: Page was swapped to auxiliary storage.

T

DAT translation status:

V: Page is valid.
P: Page is not valid.
S: Page resides in an invalid segment.
3: Page resides in an invalid region third.
2: Page resides in an invalid region second.
1: Page resides in an invalid region first.
N: DAT structures are not built for this page.
A: Page resides in an invalid space (swapped out).
U: Page is unavailable due to a hardware or software error or is in a transitional state.

R LOC

The current, or most recent, real frame number of the page. To obtain the real address of the frame, add three zeros to the right of the frame number.

LOC

The current, or most recent, location of the page. The character to the right of the location indicates the storage type.

r: Real storage
p: Paging data set
f: Storage-class memory (SCM)

A question mark (?) indicates that the storage type cannot be determined.

PAGE I/O

The type of paging I/O (if any) current for the page. A dash (-) indicates that I/O is not active. For the list of functions, see PAGE I/O.

FIX

The fix count for the page.

DG

Diagnostic data useful to IBM®.

START VSA

The beginning (lowest) virtual storage address for a memory object. This includes guard pages, therefore if GUARDLOC is specified as LOW this VSA may represent a guard page.

END VSA

The last (highest) virtual storage address for a memory object. This includes guard pages, therefore if GUARDLOC is specified as HIGH this VSA may represent a guard page.

S

An indication of the shared attribute:

N: The memory object is not shared.
L: The memory object is shared with a local scope.
G: The memory object is shared with a global scope.

K

The storage protect key for the pages in the memory object.

F

An indication of how the memory object is protected:

Y: The pages in the memory object are fetch-protected
N: The pages in the memory object are not fetch-protected

C

An indication of the control value of the memory object. The control value indicates whether the memory object should be eligible for certain other services. A dash (–) indicates that this field is not applicable such as for shared memory objects.

A: Memory object is authorized and other requests such as PAGEFIX can be performed on memory object pages.
U: Memory object is unauthorized and other requests such as PAGEFIX cannot be performed on memory object pages.

M

An indication as to whether the memory object should be included in an SVC dump when region is requested.

Y: The virtual storage in the memory object should be captured when SDATA=RGN is specified on the SVC dump request.
N: The virtual storage of the memory object is not included in the dump when SDATA=RGN is specified on the SVC dump request if not specifically requested.

CREATE TIME

The time when the memory object was created via GETSTOR or GETSHARED..

REQUESTOR

The return address of the requester of the memory object. For a shared memory object, this is the requester of the GETSHARED request.

RQAS

The address space identifier of the requester of the memory object.

USER TOKEN

The user token associated with a high virtual memory object. For shared memory objects, this is the user token for the most recent SHAREMEMOBJ request. A dash (-) indicates that no user token was specified.

SHR MEM

The number of interests the address space has in a memory object (SHAREMEMOBJ requests still active). A dash (-) indicates that no user token was specified.

RESERVED

Indicates the number of segments in hex that is reserved for optimization. A dash (-) indicates that this field is not applicable.

Totals for job cccccccc ASID hhhh (in decimal):

These totals are located at the end of each job name.

The total number, in decimal, is recorded for the virtual pages from each job name in the following page states: DASD, FREF, REAL, GUARD, SCM, SIAI, SOAI, RL_M, FRFM, SCMM, RL2G or SWAX. These states are described for the STAT field. Swap states apply to working set pages only.
