DSECT NAME - USEATE FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRUSEATE DESCRIPTIVE NAME - Monitor Event Record Domain 4 - User Domain Record 9 - User Activity Data at Transaction End DESCRIPTION - Provides information relating to a VMDBK's consumption of system resources for a transaction.

Valid only in base VMDBK 208 D0 Unsigned 4 USEATE_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 if 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. 212 D4 Unsigned 4 USEATE_VMDABSSH This 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.

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 USEATE_VMDMXSHA to determine if Max share is absolute or relative. 256 100 Character 8 USEATE_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).
