An ACR trace entry represents failure of a processor and subsequent
entry into the alternate CPU recovery component.

- PR
- pr: Identifier of the processor that produced the
TTE.
- ASID
- fail: Home address space identifier (ASID) of the
failing processor
- TCB-ADDR
- tcb-addr: Address of the task control block (TCB)
for the current task for which the TTE was produced.
- IDENT
- The TTE identifier, as follows:
- ACR
- Alternate CPU recovery.
- CD/D
- cpu: The failing processor address from the PSACPUPA
field of the PSA
- PSW----- ADDRESS-
- Blank
- UNIQUE-1/UNIQUE-2/UNIQUE-3
- UNIQUE-4/UNIQUE-5/UNIQUE-6
- flg-crex: LCCACREX field of the logical configuration
communication area (LCCA) for the failing processor.
- psacstk-: PSACSTK field from the prefix save area
(PSA) from the failing processor.
- psaeepsw: PSAEEPSW field in the PSA. Bytes 1 and 2
contain the failing processor's address. Bytes 3 and 4 contain the
external interruption code.
- psamodew: PSAMODEW field in the PSA
- psasuper: PSASUPER field in the PSA
- PSACLHS-
- psaclhs-: String for the current lock held, from
the PSACLHS field of the PSA from the failing processor.
- PSACLHSE-
- psaclhse-: Extended string for the current lock
held, from the PSACLHSE field of the PSA from the failing processor.
- PSALOCAL
- psalocal: Locally locked address space indicator,
from the PSALOCAL field of the PSA from the failing processor.
- PASD
- pasd: Primary ASID (PASID) at trace entry.
- SASD
- sasd: Secondary ASID (SASID) at trace entry.
- 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 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.
