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 Character 8 USELON_VMDUSER User logon identification 28 1C Unsigned 2 USELON_VMDCPUAD Processor address 30 1E Bitstring 1 USELON_VMDMODE Guest machine mode. This is as set for internal use by CP. See USELON_CALMODE for mode 'calculated' at. 31 1F Bitstring 1 USELON_CALSTAT User information 1... .... USELON_VMDSVMST 'OPTION SVMSTAT' has been specified in the user's directory .1.. .... USELON_VMDQDSPU This user has the QUICKDSP designation, either by default or as set 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. .... USELON_CALDIAL This user is a dialed user ...1 .... USELON_CALSNA This user is connected through System Network Architecture (SNA) .... 1... USELON_VMDNOINS User is prevented from inserting any tracks into the minidisk cache. (set when SET MDC INS OFF command is issued) .... .1.. USELON_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. .... ..1. USELON_VMDMASST Collaborative Memory Management assist enabled. Note: The VMDMAACT bit is not provided in this record because a recently logged on user would not yet be in a CMM-active or CMM-pending-off state. .... ...1 * 32 20 Unsigned 4 USELON_VMDRELSH This virtual CPU's RELATIVE share of the system, as set in the user's directory or via the SET SHARE command. Set to zero when this VMDBK has an ABSOLUTE share value, or has a virtual processor dedicated to it, or is in the process of being logged off. 36 24 Unsigned 4 USELON_VMDABSSH This virtual CPU'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 when this VMDBK has a RELATIVE share value. 40 28 Bitstring 1 USELON_CALMODE Architectural mode of the virtual machine 1... .... * .1.. .... USELON_CALMESA ESA architecture ..1. .... USELON_CALMXA XA architecture ...1 .... USELON_CALM370 370 architecture .... 1... USELON_CALMXC XC architecture .... .1.. USELON_CALMESAM ESA mode user has entered z/Arch mode. Note that at this time it is impossible for a guest to show up as having entered z/Arch at logon time because guest has not had an opportunity to issue SIGP in order to enter z/Arch mode. .... ..1. * .... ...1 * 41 29 Bitstring 1 USELON_VMDSTYPE Storage type this virtual machine resides in. X'00' => V=V. X'80' => Reserved and no longer available. X'40' => V=F. 42 2A Bitstring 1 USELON_CALSHARF Set Share flags 1... .... USELON_VMDMXSHA Max share for this CPU is ABSOLUTE if on. Max share for this CPU is RELATIVE if off. .1.. .... * ..1. .... * ...1 .... * .... 1... * .... .1.. * .... ..1. USELON_VMDLIMTH Max share for this CPU is LIMITHARD if on. Max share for this CPU is LIMITSOFT if off. .... ...1 * 43 2B Unsigned 1 * Reserved and available for IBM use. 44 2C Unsigned 4 USELON_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 USELON_ASCDEFSZ 48 30 Unsigned 4 USELON_VMDMXRVP Number of pages reserved for the user 52 34 Character 8 USELON_VMDACTNO User accounting number 60 3C Character 8 USELON_VMDGRPN RACF ACI group name 68 44 Character 8 USELON_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 USELON_VMDBYVAL The BYUSER ID that logged on this virtual machine. If there is no BYUSER, this field is binary zeros. 84 54 Unsigned 4 USELON_VMDMXSHR This virtual CPU'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 USELON_VMDMXSHA to determine if Max share is absolute or relative. 88 58 Character 8 USELON_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'). 88 58 Character 4 USELON_CALDEFHI high four bytes 92 5C Character 4 USELON_CALDEFLO low four bytes 96 60 Unsigned 4 USELON_CP_SSHRELSH This user's RELATIVE share setting for CPUs of type CP. 100 64 Unsigned 4 USELON_CP_SSHABSSH This user's ABSOLUTE share setting for CPUs of type CP. 104 68 Unsigned 4 USELON_CP_SSHMXSHR This user's Max share setting for CPUs of type CP. 108 6C Bitstring 1 USELON_CP_SSHFLG1 This user's share flags for CPUs of type CP. 1... .... * .1.. ....
