Header section
The header section for SMF record type 122, subtype 1, holds a standard SMF header followed by fields that reference the various data sections. Character strings are in EBCDIC, left aligned and padded with blanks to fill the field.
| Offsets | Type/Value | Length | Name | Description |
|---|---|---|---|---|
| 0 (x0) | Structure | 24 | SMFHDR | ** Standard SMF header ** |
| 0 (x0) | Structure | 4 | SMFRDW | ** SMF Record descriptor word ** |
| 0 (x0) | Unsigned | 2 | SMFLEN | Record length. This field and the next field (total of 4 bytes) form the record descriptor word (RDW), which is removed when the record is dumped. |
| 2 (x2) | Unsigned | 2 | SMFSEG | Spanned segment descriptor. This field and the previous field (total of 4 bytes) form the record descriptor word (RDW), which is removed when the record is dumped. |
| 4 (x4) | Bitstring | 1 | SMFFLG | SMF header flag byte. |
| .1.. .... | SMSSTV | (x40) Subtypes are being used. | ||
| 5 (x5) | Unsigned | 1 | SMFRTY | Record type: 122 (x7A) |
| 6 (x6) | Unsigned | 4 | SMFTME | Time since midnight, in hundredths of a second, that has elapsed since the record was moved into the SMF buffer (format: HHMMSSth). |
| 10 (xA) | Packed | 4 | SMFDAT | Date when the record was moved into the SMF buffer. In the form of 0cyydddF, where c is 0 for 19xx and 1 for 20xx, yy is the current year (0-99), ddd is the current day (1-366), and F is the sign. |
