DSECT NAME - PRCPRP
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header

DESCRIPTIVE NAME - Monitor Sample Record
Domain 5 - Processor Domain
Record 3 - Processor Data (Per Processor)
DESCRIPTION - Provides data related to work dispatched on a real
processor. A separate record is generated for each
real processor.

Dec Hex Type Len Name (Dim) Description
0 0 Structure 124 PRCPRP Start of monitor record
0 0 Character 0 PRCPRP_MRHDR Record header. See MRRECHDR
for details.
0 0 Character 20 MRHDR

4 4 Unsigned 1 MRHDRDM domain identifier
5 5 Unsigned 1 *
6 6 Unsigned 2 MRHDRRC record identifier
8 8 Character 8 MRHDRTOD Time at which this record was
built. In time-of-day (TOD)
clock format. See IBM System
370 XA Principle of Operation
for explanation of format.
16 10 Character 4 *
20 14 Character 0 MRHDR_END End of header
20 14 Unsigned 2 PRCPRP_PFXCPUAD Processor address
22 16 Unsigned 2 PRCPRP_PLSSTLNU(0:30) Array of counts of 'stolen'
VMDBKs, one count for each
processor from which the VMDBK
was stolen. This array does not
include the master-only
processor since its work cannot
be dispatched by another
processor.
84 54 Unsigned 4 PRCPRP_PFXDSPCS Count of 'long paths' through
the dispatcher. This is roughly
the number of times a different
user was selected to be
dispatched. It includes also
the number of times a running
user was examined to see if it
should continue to run, and was
selected to run again (no
switch made).
88 58 Unsigned 4 PRCPRP_PLSDSPCM Count of times a VMDBK was
chosen to be dispatched, then
had to be moved to the master
processor for master-only work.
This is the only time work will
be passed from a
non-master-processor to another
processor.
92 5C Unsigned 4 PRCPRP_DSVMAXUS Maximum number of users
allowed in the Processor Local
Dispatch Vector (PLDV)
96 60 Character 28 PRCPRP_HFSAMPLE
96 60 Unsigned 4 PRCPRP_HFCOUNT Number of times this
processor was sampled for high
frequency data.
100 64 Unsigned 4 PRCPRP_HFUSERZ High-frequency count. Number
of times the Processor Local
Dispatch Vector (PLDV) had no
VMDBKs
104 68 Unsigned 4 PRCPRP_HFUSERC High-frequency count. Number
of VMDBKs in the Local Dispatch
Vector (PLDV) when the PLDV was
not empty. DSVUSERC
108 6C Character 8 PRCPRP_CALUDED If processor is dedicated,
this is the userid to which it
is dedicated. Otherwise, the
field is binary zeros.
116 74 Unsigned 1 PRCPRP_PFXTYPE Host CPU usage type
identifier. Processor type is:
X'14' = Master Processor X'1E'
= Dedicated Processor X'28' =
Alternate Processor
117 75 Character 3 * Reserved and available for
IBM use.
120 78 Unsigned 4 PRCPRP_HFUSERM High-frequency count. Number
of VMDBKs in the master-only
Local Dispatch Vector (PLDV).
This varies from PRCPRP_HFUSERC
which for the master processor
is the sum of VMDBKs in both
the master-only PLDV and the
normal PLDV.
