John, The JZOS Cookbook (on alphaWorks) has code samples and a nice little class for reading RDW-delimited records. Not ugly at all :-) There are also examples in the cookbook of using the (Cobol) copy book to Java tools. The ASM Dsect utility is similar.
The difficult part of many SMF records is that they are often aggregations of subtype records. Look at the SMF 119 (FTP) records for example. The JZOS generator tool will help you with some of the low level drudgery, but it will still be a bit of work to write the code to stitch the subtypes together. If SAS is inexpensive on a PC and you can run MXG on it supported, then why not use it? Replicating even a small subset of MXG's functionality seems like a huge effort. A very slick approach is to a Co:Z batch job to launch SAS/MXG on a PC and pipe the SMF records directly into the load process. You could even kick this off with a IEFU29 exit.
