All records on the logrec data set contain a standard 24-byte header
followed by data that is specific for the record type and the device
type or machine model. The header provides the information necessary
to identify the type and origin of the record.
- Type information - which defines the specific
type of record, the specific source of the record,
the general reason the record was made, and any special record-dependent
attributes (such as record length, content, hardware features, format).
- Origin information - which includes the
operating system the record was generated on, the
generating program, the time and date the record was generated, the
processor identity, and the processor serial number on which the record
was generated. For a multiprocessing system, the processor that generated
the record may not be the processor on which the incident occurred.
