USR trace records

The USR record represents processing of a GTRACE macro. A user-supplied formatting routine (AMDUSRhh) formats the record. If a routine is not supplied, GTF prints the record without formatting.

This topic shows the unformatted and formatted records, then shows the following examples of USR records created by GTRACE macros in IBM-components:

USRF9 trace records for VSAM
USRFE trace records for BSAM, QSAM, BPAM, and BDAM
USRFF trace records for open, close, and end-of-volume (EOV)

The USRFD trace records for VTAM® are described in z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures.

USR records contain the following information useful for identifying the user program, MVS™ component, or IBM® product producing the record and the routine you can use to format the record:

Event identifiers (EIDs) identify the event that produced the record. See Event Identifiers (EIDs) for USR trace records for a list of the EIDs and associated products for USR trace records. Because each EID for USR records start with an E, unformatted USR records show just the last three numbers of the EID after the E.
Format identifiers (FIDs) identify the routine that the system used to format the USR trace record. See Format Identifiers (FIDs) for USR trace records for a list of the FIDs and associated routines.
