MRMTRUSR Prolog
DSECT NAME - MTRUSR FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRMTRUSR DESCRIPTIVE NAME - Monitor Sample Configuration Record Domain 1 - Monitor Domain Record 15 - Logged on User DESCRIPTION - Description of a logged on user at the time the MONITOR SAMPLE START command is issued. A separate record is generated for each logged-on user.

MTRUSR_VMDSVMST 'OPTION SVMSTAT' has been specified in the user's directory .1.. .... MTRUSR_VMDQDSPU This user has the QUICKDSP designation, as set or defaulted 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. .... MTRUSR_CALDIAL This user is a dialed user ...1 ....

Max share is Relative if OFF. .1.. .... * ..1. .... * ...1 .... * .... 1... * .... .1.. * .... ..1. MTRUSR_VMDLIMTH Max share is Limithard if ON. Max share is Limitsoft if OFF. .... ...1 * 36 24 Unsigned 4 MTRUSR_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 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. 40 28 Unsigned 4 MTRUSR_VMDABSSH The 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. 44 2C Unsigned 4 MTRUSR_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 MTRUSR_ASCDEFSZ 48 30 Character 8 MTRUSR_VMDACTNO User accounting number 56 38 Character 8 MTRUSR_VMDGRPN External Security Manager group name 64 40 Unsigned 4 MTRUSR_VMDMXRVP Number of pages reserved for the user 68 44 Character 8 MTRUSR_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 MTRUSR_VMDBYVAL The BYUSER ID that logged on this virtual machine. If there is no BYUSER, this field is binary zeros. 84 54 Unsigned 4 MTRUSR_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 MTRUSR_VMDMXSHA to determine if Max share is absolute or relative. 88 58 Character 8 MTRUSR_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 MTRUSR_CALDEFHI high four bytes 92 5C Character 4 MTRUSR_CALDEFLO low four bytes 96 60 Character 0 MTRUSR_END
