I always considered the performance impact to be minimal, and being lazy by nature, my tendency has been to just do a full refresh. It's hard to imagine how the performance impact would have been reduced, though. It still has to read all those directories. At my last shop, a full refresh has been known to cause problems for the IMS folks. I never understood why, and they claim that it was not because they had prestaged updates to LLA managed data sets. Knowing what I do about the change management process there, I tend to believe them. I do know that there were times that they came looking for me because I had performed a full refresh and they had to cycle some IMS regions. I don't know what else they might have been managing with LLA. Remember that it's not just for linklist. -- Tom Marchant ---------------------------------------------------------------------- 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
