You might check for ACD's - LISTF udc_file,-2. MPE/ix 5.0 through PP 6 will sometimes add an ACD pair [log in to unmask]@ : RACD'... Reason is unknown to me.. We've had them show up on device files, MPE files, and Image 'GB' files. They are sometimes removable but we have also had to add another pair to make the files available. ______________________________ Reply Separator _________________________________ Subject: still a udc problem Author: Terry Prime <[log in to unmask]> at Internet-Gateway Date: 2/11/97 5:15 PM MPE 5.0 powerpatch 4. I set the file UDCFILE.GEN.SYS as :- READ :AC WRITE :AC APPEND :AC LOCK :ANY EXECUTE :ANY **SECURITY IS ON I set the group GEN.SYS as :- READ :GU WRITE :GU APPEND :GU LOCK :ANY EXECUTE :ANY SAVE :GU The account SYS is :- READ :ANY WRITE :AC APPEND :AC LOCK :ANY EXECUTE :ANY According to the information I was given, this is all that is needed for a user to be able to read/access the UDC. Unfortunately not - it did not work, the UDC could still not be accessed while it was secure. No wonder I am going bald!!!!!!! regards ...
