Juergen, There are two possible usermods for LE. If you have CEEDOPT or CEECOPT, these are installation wide options. The CEEPRMxx parmlib member will only affect that LPAR, and you can also have a CEEROPT usermod for a particular region.
So to answer your question, you can use both. CEEPRMxx will over-ride CEEDOPT for that LPAR. You can check what's being used with the D CEE,ALL command. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
