     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.
                   A separate record is generated for each VMDBK in a
                   virtual complex that contributed to the transaction.
