USRn trace entries

A USRn trace entry represents processing of a PTRACE macro in an authorized program. The trace entry contains data from the macro.

PR

pr: Identifier of the processor that produced the TTE.

ASID

home: Home address space identifier (ASID) associated with the TTE.

TCB-ADDR

tcb-addr: Address of the task control block (TCB) for the current task or the work element block (WEB).

IDENT

The TTE identifier, as follows:

USRn: User event. n is a number from X'0' to X'F'.

CD/D

Blank

PSW----- ADDRESS-

return: Return address of the program that issued the PTRACE macro

UNIQUE-1/UNIQUE-2/UNIQUE-3

UNIQUE-4/UNIQUE-5/UNIQUE-6

data----: User-defined data from the PTRACE macro
idc-: PTRACE identification count
rbc: Relative byte count

PSACLHS-

This field contains descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP/SYSUDUMP/SYSABEND output.

PSALOCAL

This field contains descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP/SYSUDUMP/SYSABEND output.

PASD

pasd: Primary ASID (PASID) at trace entry. This field contains descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP/SYSUDUMP/SYSABEND output.

SASD

sasd: Secondary ASID (SASID) at trace entry. This field contains descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP/SYSUDUMP/SYSABEND output.

TIMESTAMP-RECORD

timestamp-------: Time-of-day (TOD) clock value when system trace created the trace entry. The value is in the same format as the time stamp on the logrec data set records.

CP

The CP column contains 2 hex digits of the processor model dependent information, which is intended to identify the physical CP that made the trace entry. CP is only provided when formatting SYSTRACE under IPCS. CP is not provided for SYSUDUMP, SYSABEND, or SNAP.
