There is also a branch entry path if using the SMFEWTM macro instead of SMFWTM. But this is a nit. I don't know which form DB2 uses. Another big consideration in favor of SMF is that IBM has made SMF the flagship vehicle for getting accounting/performance data out of MVS. Great pains have been taken to optimize the I/O performance of the SMF writer (but GTF is not too shabby, either). And a full SMF data set can be automatically switched to start recording in a different, empty SMF data set. As far as I know, GTF does not have such a facility. A few years ago another problem with GTF was that there could only be one GTF running in an MVS image, and anyone who needed GTF data for debugging had to wait for the SMF-capturing GTF to end. But now you can have multiple GTFs running simultaneously. Bill Fairchild Plainfield, IL
