MTRUSR_CALMODE for the mode
'calculated' at.
31 1F Unsigned 1 MTRUSR_VMDCPUCT Number of guest defined CPUs
32 20 Bitstring 1 MTRUSR_CALSTAT User information
1... .... MTRUSR_VMDSVMST 'OPTION SVMSTAT' has been
specified in the user's directory
.1.. .... MTRUSR_VMDQDSPU This user has the QUICKDSP
designation, as set or defaulted
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. .... MTRUSR_CALDIAL This user is a dialed user
...1 .... MTRUSR_CALSNA This user is connected through
System Network Architecture (SNA)
.... 1... MTRUSR_VMDNOINS User is prevented from inserting
any tracks into the minidisk
cache. (set when SET MDC INS OFF
command is issued)
.... .1.. MTRUSR_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.

34 22 Bitstring 1 MTRUSR_VMDSTYPE Storage type this virtual
machine resides in. X'00' => V=V.
X'80' => V=R. X'40' => V=F.
35 23 Bitstring 1 MTRUSR_CALSHARF Set Share flags

36 24 Unsigned 4 MTRUSR_VMDRELSH This user's RELATIVE share of
the system, as set in the user's
directory or via the SET SHARE
command. Set to zero if the user
is an ABSOLUTE share user or this
VMDBK has a virtual processor
dedicated to it, and the user is a
virtual MP user. Set to a negative
value if VMDBK has a virtual
processor dedicated to it, and the
user is a virtual UP user.
40 28 Unsigned 4 MTRUSR_VMDABSSH The user'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 if
user is a RELATIVE share user.
44 2C Unsigned 4 MTRUSR_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
MTRUSR_ASCDEFSZ
48 30 Character 8 MTRUSR_VMDACTNO User accounting number
56 38 Character 8 MTRUSR_VMDGRPN External Security Manager group
name
64 40 Unsigned 4 MTRUSR_VMDMXRVP Number of pages reserved for the
user
68 44 Character 8 MTRUSR_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 MTRUSR_VMDBYVAL The BYUSER ID that logged on
this virtual machine. If there is
no BYUSER, this field is binary
zeros.
84 54 Unsigned 4 MTRUSR_VMDMXSHR The user'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 MTRUSR_VMDMXSHA to determine
if Max share is absolute or
relative.
88 58 Character 8 MTRUSR_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').
