Header/Self-defining Section

This section contains the common SMF record headers fields and the triplet fields (offset/length/number), if applicable, that locate the other sections on the record.

Offsets		Name	Length	Format	Description
0	0	SMF7LEN	2	binary	Record length. This field and the next field (total of four bytes) form the RDW (record descriptor word). See Standard SMF record header for a detailed description.
2	2	SMF7SEG	2	binary	Segment descriptor (see record length field).
4	4	SMF7FLG	1	binary	System indicator: Bit Meaning when set 0-2 Reserved 3-6 Version indicators (see Standard SMF record header for details) 7 Reserved.
5	5	SMF7RTY	1	binary	Record type 7 (X'07').
6	6	SMF7TME	4	binary	Time since midnight, in hundredths of a second, when the record was built into the SMF buffer.
10	A	SMF7DTE	4	packed	Date when the record was moved into the SMF buffer, in the form 0`cyydddF`. See Standard SMF record header for a detailed description.
14	E	SMF7SID	4	EBCDIC	System identification (from the SID parameter).
18	12	SMF7NRO	2	binary	Number of SMF records lost because no SMF data sets were available for recording. Unsigned, count up to 65,535. This field is marked as invalid, and is set to zero when SMF7NRF is ON. SMF7NROX is the 4 byte equivalent of this field.
20	14	SMF7STM	4	binary	When SMF7DRP is off, this is the time when the buffers condition began. When SMF7DRP is on, this is the time when the DROP record filter became active. This field is in hundredths of a second.
24	18	SMF7STD	4	packed	When SMF7DRP is off, this is the date when the buffers condition began. When SMF7DRP is on, this is the date when the DROP record filter became active. This field is in packed decimal format: 00`yydddF`.
28	1C	SMF7FL1	1	binary	Flag byte: Bit Meaning when set 0 Bit SMF7NRF indicates that field SMF7NRO has exceeded its 2 byte capacity and is therefore invalid. Use SMF7NROX, which is the 4 byte equivalent of SMF7NRO. 1 Bit SMF7LSD indicates that this record is the result of a log stream becoming full. 2 Bit SMF7DRP indicates that this record is the result of the SMF record flood facility dropping records. 3- 7 Reserved.
29	1D	SMF7RSV1	2		Reserved.
31	1F	SMF7DTYP	1	character	The type of record that was dropped by the filter. This field is zero unless SMF7DRP is ON.
32	20	SMF7NROX	4	binary	Number of SMF records lost because no SMF data sets were available for recording. Unsigned, 4 byte equivalent of SMF7NRO.
36	24	SMF7LSN	26	character	The name of the log stream associated with the data space that experiences the loss. Only filled in when SMF7LSD is ON.
