1... .... USELON_VMDSVMST 'OPTION SVMSTAT' has been
specified in the user's
directory
.1.. .... USELON_VMDQDSPU This user has the QUICKDSP
designation, either by default
or as set by the SET QUICKDSP
command. When the user has work
to do, it will be added to the
dispatch list immediately
without waiting in the eligible
list.
..1. .... USELON_CALDIAL This user is a dialed user
...1 .... USELON_CALSNA This user is connected
through System Network
Architecture (SNA)
.... 1... USELON_VMDNOINS User is prevented from
inserting any tracks into the
minidisk cache. (set when SET
MDC INS OFF command is issued)
.... .1.. USELON_VMDNOFSL No MDC fair share limit
applies. Set at LOGON if the
NOMDCFS option is specified on
the OPTIONS statement in the
user's directory.
.... ..1. USELON_VMDMASST Collaborative Memory
Management assist enabled.
Note: The VMDMAACT bit is not
provided in this record because
a recently logged on user would
not yet be in a CMM-active or
CMM-pending-off state.
.... ...1 *
32 20 Unsigned 4 USELON_VMDRELSH This virtual CPU's RELATIVE
share of the system, as set in
the user's directory or via the
SET SHARE command. Set to zero
when this VMDBK has an ABSOLUTE
share value, or has a virtual
processor dedicated to it, or
is in the process of being
logged off.
36 24 Unsigned 4 USELON_VMDABSSH This virtual CPU's ABSOLUTE
share of the system, as set in
the user's directory or via the
SET SHARE command. Unit of
value is a hexadecimal factor
scaled 16 bits. For example,
X'00010000' = 1.00(100%),
X'0000C000' = 0.75(75%),
X'00008000' = 0.50(50%), etc.
Set to zero when this VMDBK has
a RELATIVE share value.
40 28 Bitstring 1 USELON_CALMODE Architectural mode of the
virtual machine
1... .... *
.1.. .... USELON_CALMESA ESA architecture
..1. .... USELON_CALMXA XA architecture
...1 .... USELON_CALM370 370 architecture
.... 1... USELON_CALMXC XC architecture
.... .1.. USELON_CALMESAM ESA mode user has entered
z/Arch mode. Note that at this
time it is impossible for a
guest to show up as having
entered z/Arch at logon time
because guest has not had an
opportunity to issue SIGP in
order to enter z/Arch mode.
.... ..1. *

41 29 Bitstring 1 USELON_VMDSTYPE Storage type this virtual
machine resides in. X'00' =>
V=V. X'80' => Reserved and no
longer available. X'40' => V=F.
42 2A Bitstring 1 USELON_CALSHARF Set Share flags
1... .... USELON_VMDMXSHA Max share for this CPU is
ABSOLUTE if on. Max share for
this CPU is RELATIVE if off.

43 2B Unsigned 1 * Reserved and available for
IBM use.
44 2C Unsigned 4 USELON_VMDSSIZE Virtual machine size, in
bytes. This field is kept for
compatability reasons, but may
not be accurate for z/Arch
systems where larger virtual
machines are valid. The
preferred field is
USELON_ASCDEFSZ
48 30 Unsigned 4 USELON_VMDMXRVP Number of pages reserved for
the user
52 34 Character 8 USELON_VMDACTNO User accounting number
60 3C Character 8 USELON_VMDGRPN RACF ACI group name
68 44 Character 8 USELON_CALTODON Time at which the user logged
on for this session. In
time-of-day (TOD) clock format.
To get the user's connect time,
subtract this time value from
the time stamp in the record
header's MRHDRTOD.
76 4C Character 8 USELON_VMDBYVAL The BYUSER ID that logged on
this virtual machine. If there
is no BYUSER, this field is
binary zeros.
84 54 Unsigned 4 USELON_VMDMXSHR This virtual CPU's Max share
of the system, as set in the
user's directory or via the SET
SHARE command. This value is
set to zero if no Max share
exists. If the Max share is
Absolute, then the unit of the
value is a hexadecimal factor
scaled 16 bits. For example,
X'00010000' = 1.00(100%),
X'0000C000' = 0.75(75%),
X'00008000' = 0.50(50%), etc.
Check USELON_VMDMXSHA to
determine if Max share is
absolute or relative.
88 58 Character 8 USELON_ASCDEFSZ Defined storage size in
addressable bytes, minus one.
If DEF STOR CONFIG was used to
define multiple discontiguous
extents of addressable defined
storage, this field contains
the sum of the sizes in bytes
of all of the individual
extents (minus one). The minus
one notation is used so that a
total size of 16 Exabytes may
be represented without
ambiguity (as
x'FFFFFFFF_FFFFFFFF').
