No apologies necessary, Jack. Thanks for this follow-up post. In the absence of any naysayers, I'll increase the values to 10 the next chance I get.

I went back through my init deck notes and found a comment from 10 OCT 1999 saying that I set most of the PCEDEFs to 10 based on Chip Wood's presentation at SHARE 93. (Chicago, AUG 1999) This was probably session 2658 JES2 Configuration & Tuning Tips. SHARE's online handouts do not appear to go back that far, but the abstract for the session said: Is your JES system running as well as it should? There are some simple things you may be able to do which can improve the efficiency or availability of your system. In this session, a representative from JES2 development will discuss: (.) Initialization statements which must be coded, or for which the default is not the best choice, (.) Tuning tips to improve performance of checkpoint and spool, (.) Recommendations for maximizing the availability of your JESplex. I would guess that I would not have set these values to the max if any potential downside had been mentioned at the session. /jack ---------------------------------------------------------------------- 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
