QUERY NSS
906 z/VM: CP Commands and Utilities Reference
ENDPAG
specifies the ending page number of a page range of the NSS or saved
segment. For a segment space, this is the ending page number of the entire
segment space.
TYPE
identifies the page descriptor code of a page range of the NSS or saved
segment. It indicates the type of virtual machine access permitted to pages in
the range. See the DEFSEG or DEFSYS command for a more detailed
discussion of page descriptor codes. Valid codes are:
Code Meaning
EW Exclusive read/write access
EN Exclusive read/write access, no data saved
ER Exclusive read-only access
SW Shared read/write access
SN Shared read/write access, no data saved
SR Shared read-only access.
SC CP writable pages, shared read-only access by virtual machine, no data
saved.
The page range type may not apply to the entire range of a segment space;
therefore a dash (–) is used when describing these files.
CL
indicates the file class. The possible file classes are:
Class Meaning
A The file is in the available state. This means that the file has been
defined and saved. To determine whether the file is in use, examine the
#USERS field in the response from the QUERY NSS command with the
MAP option.
P The file is in the pending purge state. It is purged when the last virtual
machine releases the NSS or saved segment, or during the next
system IPL or RESTART.
R The file is in the available state but has restricted access. To determine
whether the file is in use, examine the #USERS field in the response
from the QUERY NSS command with the MAP option. Access to an
NSS, DCSS, or segment space name with this class requires a
NAMESAVE directory entry for the NSS, DCSS, or segment space
name.
S The file is in the skeleton state. This means that the file has been
defined by a DEFSEG or DEFSYS command. The SAVESEG or
SAVESYS can now be processed to complete this system data file.
#USERS
specifies the number of users attached to the NSS or saved segment.
Note: The number of users pertains to that file name only.
PARMREGS
for NSS files only, identifies the registers in which parameters are passed to the
virtual machine at IPL. Possible values are:
Value Meaning
m-n A range of registers, where m and n are decimal integers between 00
and 15 (inclusive) and m is less than or equal to n.
