Offsets Dec Hex Type Len Name (Dim) Description 0 0 Structure 228 MTRMEM Start of monitor record 0 0 Character 0 MTRMEM_MRHDR Record header. See MRRECHDR for details. 0 0 Character 20 MRHDR 0 0 Unsigned 2 MRHDRLEN 2 2 Unsigned 2 MRHDRZER 4 4 Unsigned 1 MRHDRDM 5 5 Unsigned 1 * 6 6 Unsigned 2 MRHDRRC 8 8 Character 8 MRHDRTOD 16 10 Character 4 * 20 14 Character 0 MRHDR_END 20 14 Unsigned 4 MTRMEM_RSASTORE Cardinal count of actual real storage size, in bytes, calculated during system initialization. This field is kept for compatability and may not be accurate for z/Arch systems. The preferred field is MTRMEM_RSAGSTOR. 24 18 Unsigned 4 MTRMEM_SYSTORS Storage size of the real machine (sysgenned storage) in bytes. This field is kept for compatability and may not be accurate for z/Arch systems. The preferred field is MTRMEM_SYSGTORS. 28 1C Unsigned 4 * Reserved for IBM use. Previous field is no longer meaningful. (MTRMEM_SYSVRSZ) 32 20 Unsigned 4 * Reserved for IBM use. Previous field is no longer meaningful. (MTRMEM_SYSVRFRE) 36 24 Unsigned 4 MTRMEM_SYSTRAC Cardinal count of frames that are used for CP trace pages for the master processor. For alternate processors, the size of the trace table is a percentage of this value as reported in MTRMEM_SYSTRCPC. 40 28 Address 4 MTRMEM_HCPMM1 Address of the Marker module to mark the start of the resident executable modules 44 2C Address 4 MTRMEM_HCPMM4 Address of the Marker module to mark the boundary between resident and pageable modules. But since we have no more Pageable modules, this effectively marks the end of the executable nucleus. However, HCPMM3 officially provides the "end of nucleus" marker and should continue to be used for that purpose. 48 30 Unsigned 4 MTRMEM_RSAPGABL Cardinal count of <2G pageable frames in the system. This includes those that had been made non-pageable (see MTRMEM_RSANONPG). The size of the dynamic area (DPA) or the count of useable frames may be calculated by subtracting RSANONPG from RSAPGABL. See MTRMEM_RSALGFRM for the >2G field for the count of useable frames. NOTE: There is no separate count for pageable frames (RSAPAGBL) and frames made non-pageable (RSANONPG) >2G. 52 34 Unsigned 4 MTRMEM_RSANONPG Cardinal count of <2G pageable frames in the system that have been made non-pageable. This includes pages locked for I/O, CP LOCK command, virtual system lock functions, etc. See MTRMEM_RSAPGABL and MTRMEM_RSALGFRM. 56 38 Unsigned 4 MTRMEM_RSAOFFLN Cardinal count of off-line frames <2G. See MTRMEM_RSAGOFFL for the >2G value. 60 3C Unsigned 4 * Reserved for IBM use. Previous field is no longer meaningful. (MTRMEM_RSARIOSZ) 64 40 Unsigned 2 MTRMEM_SYSTRCPC Percentage of master processor trace table size to be used for alternate processors. Percentage applies to secondary processors as well. 66 42 Bitstring 1 MTRMEM_FLG1 Flag byte 1... .... MTRMEM_RSAAASTA Anti-aliasing status bit. .1.. .... * ..1. .... * ...1 .... * .... 1... * .... .1.. * .... ..1. * .... ...1 * 67 43 Character 1 * Reserved for IBM use. 68 44 Address 4 MTRMEM_HCPMM0 Address of the Marker module to mark the start of resident MP modules. 72 48 Address 4 MTRMEM_HCPSYS Address of the HCPSYS module which is the start of the resident CP nucleus. 76 4C Unsigned 4 MTRMEM_CALSCMAX When MTRSYS_CALFLG2 <> x'80' (format-0 measurement blocks), this is the total number of SCMBKs contained in the contiguous storage set aside for the SCMBK area. When When MTRSYS_CALFLG2 = x'80' (format-1 measurement blocks), this is the total number of SCGBKs allocated. 80 50 Unsigned 4 MTRMEM_SYSSCMEX Number of extra pages requested for the SCMBK area in the system config file. 84 54 Character 8 MTRMEM_SYSGTORS The sysgen specified storage size minus 1 byte. This includes storage above 2GB. The minus one notation is used so that a total size of 16 Exabytes may be represented without ambiguity (as x'FFFFFFFF_FFFFFFFF'). 92 5C Character 8 MTRMEM_RSAGSTOR The actual real storage size minuz 1 byte. This is calculated at system initialization and includes storage above 2GB. The minus one notation is used so that a total size of 16 Exabytes may be represented without ambiguity (as x'FFFFFFFF_FFFFFFFF'). 100 64 Character 8 MTRMEM_RSAGOFFL Cardinal count of off-line frames >2G. See MTRMEM_RSAOFFLN for the <2G value. 108 6C Character 8 MTRMEM_RSALGFRM Cardinal count of >2G useable frames. See MTRMEM_RSAPGABL and MTRMEM_RSANONPG for the <2G value. 116 74 Unsigned 4 MTRMEM_SXSSIZE System Execution Space size in pages. 120 78 Character 8 MTRMEM_PFXSTLEN Length of the System Execution Space page management table. 128 80 Character 8 MTRMEM_PFXFTLEN Length of the frame table. 136 88 Character 8 MTRMEM_RSAFNOTI Count of the not initialized FRMTEs >=2G. 144 90 Character 8 MTRMEM_SYSGSTBY The standby real storage size in bytes 152 98 Character 8 MTRMEM_SYSGSTRS The reserved real storage size in bytes 160 A0 Unsigned 4 MTRMEM_RSACKMB2G Count of CP frames below 2G allocated as stand-alone dump crashkernel memory. The count is not included in RSADmpCP. This field is only updated during system init. 164 A4 Unsigned 4 MTRMEM_RSACKMA2G Count of CP frames above 2G allocated as stand-alone dump crashkernel memory. The count is not included in RSADmpCP. This field is only updated during system init. 168 A8 Character 8 MTRMEM_RSAPIN0B Cardinal count of the system total pinned pages class 0 below 2G 176 B0 Character 8 MTRMEM_RSAPIN0A Cardinal count of the system total pinned pages class 0 above 2G 184 B8 Character 8 MTRMEM_RSAPIN1B Cardinal count of the system total pinned pages class 1 below 2G 192 C0 Character 8 MTRMEM_RSAPIN1A Cardinal count of the system total pinned pages class 1 above 2G 200 C8 Unsigned 4 MTRMEM_RSAPINWP Cardinal percent of the total pinned page count compared to the DPA that causes a warning message when a pin request is made. 204 CC Unsigned 4 MTRMEM_RSAPINFP Cardinal percent of the total pinned page count compared to the DPA that causes a pin request to to fail. 208 D0 Character 8 MTRMEM_RSAIOUSD Cardinal current usage in BYTES of the IOAT subpool storage. 216 D8 Unsigned 4 MTRMEM_RSAIOSIZE Cardinal size in MB of of the IOAT subpool. 220 DC Unsigned 4 MTRMEM_RSAIOWRNP Cardinal percent of the IOAT subpool current usage compared to the size when a warning message is issued. 224 E0 Unsigned 2 MTRMEM_SYSHPIOM Maximum number of concurrent I/O requests to a paging volume 226 E2 Unsigned 1 MTRMEM_SYSHPFLG HyperPAV paging flags 1... ....
