Re: How can I keep JES2 from being SYSPLEXed?
Okay this wakes up some retired brain cells. Because tasks communicate across XCF (even when you don't know about it) they have to have a unique identifier for things to work properly. Some tasks will create a unique identifier by default and some will not. I forgot about that little item. I'm glad things are now working for you.

Re: C++ and Linker/Binder parameters for "called as subprogram"
I wanted to close the loop on this, and frankly, vent a little bit. I played around and played around with different C++ and LE options -- nothing seemed to make a big difference. So finally I wrote a trivial, 3-machine instruction, do-nothing ADATA exit in HLASM. It turns out the overhead is not in C++ and LE -- it's in the COBOL compiler calling exits! Here are the numbers -- CPU seconds, details below -- for various situations: NOADATA: 1.91 CPU seconds ADATA to DUMMY: 1.935 CPU seconds ADATA to DASD: 2.04 CPU seconds ADATA to DUMMY, 3-instruction exit: 2.82 CPU seconds -- an overhead of over 45 percent! Details: REGION=0M, COBOL 6.2, up-to-date on PTFs, typical options, OPT(0), 52,063 lines, 34,012 statements, z14-M01, TCB+SRB time per IEF033I. All tests run on a reasonably quiet LPAR. Gr!

Re: Masking SMF data internally
Jake, I agree you need to identify what record types are needed for the sizing operation. After you know which record types (and subtypes) you may not need to do anything. As an example, I can't think of any sensitive data that might be in the SMF type 7x records.
