32 20 Character 8 USEATE_VMDTTIME Total time which has been
expended on this VMDBK. This
includes time which the VMDBK
spent doing its own work and also
time which CP spent doing work on
behalf of the VMDBK. It is in CPU
timer format. The complement of
this field is the elapsed time in
TOD clock units.
40 28 Character 8 USEATE_VMDVTIME Total time that this user was
running, doing productive work. It
does not include any time that CP
spends on behalf of that user
doing such things as instruction
simulation or page translation.

204 CC Unsigned 4 USEATE_VMDCTISO Number of times ISOLATE occurred
for spaces owned by this virtual
system. Valid only in base VMDBK
208 D0 Unsigned 4 USEATE_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 if
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.
212 D4 Unsigned 4 USEATE_VMDABSSH This 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.
216 D8 Unsigned 4 USEATE_VMDSSIZE Virtual machine size, in bytes.
This field is kept for
compatability reasons, but may not
be accurate for 64-bit systems
where larger virtual machines are
valid. The preferred field is
USEATE_ASCDEFSZ
220 DC Unsigned 4 USEATE_VMDMXRVP Number of pages reserved for the
user
224 E0 Character 8 USEATE_VMDACTNO User accounting number
232 E8 Character 8 USEATE_VMDGRPN RACF ACI group name

virtual disk in storage.
252 FC Unsigned 4 USEATE_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 USEATE_VMDMXSHA to determine
if Max share is absolute or
relative.
256 100 Character 8 USEATE_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').
256 100 Character 4 USEATE_CALDEFHI high four bytes
260 104 Character 4 USEATE_CALDEFLO low four bytes
264 108 Unsigned 4 USEATE_VMDCTPVG Count of private address space

moved a page on behalf of this us
user from a frame with address >=
2GB to one < 2GB. This field is
only valid in the base VMDBK.
