SPIN trace entries

A SPIN trace entry represents the starting (at least one second in), the middle (when special processing is done), or the stopping of a system spin attempting to obtain a resource. The spinning module will identify the resource within the trace entry.

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:

SPIN: System spin.

CD/D

The CD/D field indicates the spinning module, using the last two or three characters of its module name, followed by a forward slash (/) and S (start), M (middle), or P (stop). For more information about each spinning module, see Spinning modules.

PSW----- ADDRESS-

return--: Caller's return address

UNIQUE-1/UNIQUE-2/UNIQUE-3

UNIQUE-4/UNIQUE-5/UNIQUE-6

For more information about each spinning module, see Spinning modules.

PSACLHS-

psaclhs-: String for the current lock held, from the PSACLHS field of the PSA.

PSACLHSE-

psaclhse-: Extended string for the current lock held, from the PSACLHSE field of the PSA.

PSALOCAL

psalocal: Locally locked address space indicator, from the PSALOCAL field of the PSA.

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 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.
