Bill, thanks for the insight. Much appreciated. I only need two USR events (FD0 and FD4) that, as I understand it, PSF writes with the GTRACE macro. So GTF will then only need to listen for GTRACE events and that will reduce the overhead quite a bit, right?
I'll follow your advice to only start 1 GTF instance. -- Peter Hunkeler CREDIT SUISSE ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
