Record mapping

The SMF type 7 record is mapped as follows.

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 and extended SMF record headers 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 and extended SMF record headers 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 0cyydddF. See Standard and extended SMF record headers 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: 00yydddF.
28 1C SMF7FL1 1 binary Flag byte:
Bit (Name)
Meaning when set
0 (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 (SMF7LSD)
Indicates that this record is the result of a log stream becoming full.
2 (SMF7DRP)
Indicates that this record is the result of the SMF record flood policy dropping records.

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. Start of changeSMF7DTYPX is the 2-byte equivalent of this field.End of change
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.
62 3E SMF7TBLS 8 binary The number of bytes lost during SMF initialization. This field will be non-zero if the SMF temporary buffer is exhausted and, therefore, records are lost during SMF initialization.

This field is only valid when SMF7DRP is on. This field is the 2–byte equivalent of SMF7DTYP. It reports all record type values (0–2047). When the dropped record type is a value greater than 255, SMF7DTYP will contain a value of 126, which is the extended type indicator value.End of change
