DSECT NAME - PRCPRP FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRPRCPRP 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. NOTES: Domain 5 Record 17 (MRPRCRCD) and Domain 5 Record 18 (MRPRCDHF) are intended to replace this record. If these records are present in monitor data, they should be used instead of this record.

Previously this field was PRCPRP_PLSSTLNU, which was an array of steal counts. See MRPRCDHF for replacement steal counts. 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 * Reserved for IBM use. Previously this field was PRCPRP_DSVMAXUS, which was the maximum number of users allowed in the Processor Local Dispatch Vector (PLDV). See PRCDHF_SYSDVENT in MRPRCDHF which has replaced this field. 96 60 Unsigned 4 *(3) Reserved for IBM use. Previously this field was PRCPRP_HFSAMPLE, PRCPRP_HFCOUNT, PRCPRP_HFUSERZ, and PRCPRP_HFUSERC. See MRPRCHDF for replacement high frequency sampling data for dispatch vectors. 108 6C Character 8 * Reserved for IBM use. Previous field is no longer meaningful. (PRCPRP_CALUDED) 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 X'32' = Parked Processor 117 75 Character 3 * Reserved and available for IBM use. 120 78 Unsigned 4 * Reserved for IBM use. Previously this field was PRCPRP_HFUSERM. See MRPRCDHF for replacement high frequency sampling data for dispatch vectors. 124 7C Unsigned 4 *(0:63) Reserved for IBM use. Previously this field was PRCPRP_PLSSTLCT, which was an array of steal counts. See MRPRCDHF for replacement steal counts. 380 17C Unsigned 1 PRCPRP_PFXCPUTY Processor type. Valid values: X'00' - General Purpose (CP) X'02' - zSeries Application Assist (zAAP) X'03' - Integrated Facility for Linux (IFL) X'04' - Internal Coupling Facility (ICF) X'05' - zSeries Integrated Information (zIIP) 381 17D Unsigned 1 PRCPRP_PFXSTATE CPU Operating Status Valid values: 000 x'00' CPU is online and available 022 x'16' Attempting to quiesce this CPU so it can be taken offline 044 x'2C' CPU has been quiesced and is in disable wait state so it can be taken offline 055 x'37' CPU is check-stopped 066 x'42' CPU is now logically offline 110 x'6E' CPU is physically offline 238 x'EE' CPU is in an unknown state (SIGP communication failure) 130 x'82' CPU is being brought online 382 17E Character 2 * Reserved for IBM use 384 180 Character 0 PRCPRP_END
