The suggestion about waiting until you get to 1.11 is stellar and decrease the complexity by some factor. In general I attended SHARE a few years ago when going to zFS was the Hot Topic. We had converted totally over to zFS. Seems to me IBM said the future was zFS and HFS was being phased out. Kinda stopped looking for the drop- dead date after that. Maybe the direction has changed to keep both around. In general at the time, the hot topic was having many, many, many, many, etc, objects in one zFS directory and the lookup to find the member ATE your CPU alive in a Parallel Sysplex. IBM promised they were looking into improving that performance. Until it was redesigned it was "Don'ta do it" or if it hurts to touch it, do not touch it. Hopefully that problem has been addressed. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
