Hello Stan,
SMF log blocks are mapped to include more information than just a single
SMF record per block. The structure of the log block is not provided as an IBM
external interface. IXGxxx services are programming interfaces, but they are
not specifically intended for reading records from SMF log blocks. As you
noted, the intended interfaces to retrieve SMF records from log streams are the
IEFU8x exits, IFASEXIT, or IFASMFDL. There is also a 'real time' interface,
provided via the INMEM SMFPRMxx option. ZEDC compressed data is decompressed
by IFASMFDL or IFASEXIT. The IEFU8x exits receive the data in its pre
compressed form.
Regards, Bonnie Ordonez, SMF Level 3
