Trace Table Codes

Trace code table entries come in two flavors: 32-byte and 64-byte. The 32-byte entry format is shown in Figure 1. The 64-byte entry format is shown in Figure 2.

Contents
X'00'
X'74', which indicates a CP trace table entry.
X'01'
Unused (zeros).
X'02'
The contents of the time-of-day clock at the time the event being traced occurred.
X'08'
Model-dependent value.
X'0A'
The trace ID or trace entry code, which defines the event.
X'0C'
The contents of register n.
X'10'
The contents of register n+1.
X'14'
The contents of register n+2.
X'18'
The contents of register n+3.
X'1C'
The contents of register n+4.

The format of a trace table entry and TRACE ID codes are described by the TTABK. The format of a trace table page and its forward/backward pointers (last two words) are described by the TTPBK.

The following summarizes the event-specific information that CP records in its trace table entries from bytes X'0A' to X'1F' (for 32-byte entries), or from bytes X'0E' to X'3F' (for 64-byte entries).

Note:
  1. These fields are generated only by HCPPAH and HCPPAU. HCPVOD, HCPVOS, and HCPVIR generate zeros (00 00 00 00).
  2. CPSYSCD is filled in for non-APPC paths, Flags2 is filled in for APPC paths.
  3. IOR|TRQSCHED - Bit seven in this field indicates whether this field contains the address of the TRQBK (the bit is on) or the address of the IORBK (the bit is off).
  4. If CC equals 0, the PTHBK Address is traced. If CC does not equal 0, the PTHBK could not be located and the path ID requested is traced.
  5. If a system error invoked a soft ABEND, which was set to SNAPDUMP by the SET ABEND command, a value of 80 00 00 00 will be present. A value of 40 00 00 00 will be present if invoked by the HCPABEND macro with SNAPDUMP as the defined ABEND type.
  6. For Diagnose X'18' results, this is the DBCMAXSZ block size.
  7. This flag byte is dependent on the operation type as defined by DBCSWTC2.
    • When DBCSWTC2 bit 5 is on (X'04'), this field contains DBCDOPER
    • When DBCSWTC2 bit 6 is on (X'02'), this field contains DBCBOPER
    • When DBCSWTC2 bit 7 is on (X'01'), this field contains DBCA4SWT
    • When none of the previous bits are on, this field contains DBC18SWT.
  8. This field varies based on the temporary diagnostic code given to the customer by the VM Service organization.
