Common IBM MQ SMF header
Use this topic as a reference to the common IBM MQ SMF header type accounting record.
The format of this record is described in Table 1 and in assembler macros thlqual.SCSQMACS(CSQDQWHS) and thlqual.SCSQMACS(CSQDQWHC), and C header file thlqual.SCSQC370(CSQDSMFC). The field names in C are all in lowercase, for example qwhs, qwhsnsda.Details of the structures and fields can be found in IBM MQ supportpac MP1B.
The QWHS data includes the subsystem name. For subtype 1 records, it also shows whether there are queue-level accounting records present. If the QWHSNSDA field is 3 or less, there are not, and the corresponding self-defining section (at offset X'34') is not set.
The QWHC data gives you information about the user (for example, the user ID (QWHCAID) and the type of application (QWHCATYP)). The QWHC section is completed only for subtype 0 records. The equivalent information is present in the thread identification record for subtype 1 and 2 records.
