Luis, This sounds like a question based in Unix terms.
Access to resources (programs, TSO, datasets etc.) on a z/OS system is controlled by one of three security products. RACF from IBM, Top Secret from CA or ACF2 also from CA. "Rules" are defined within these products. To determine which users and what level of access they have you'll need to query the Security Product. It's not as simple as seeing the permission bits associated with a file name as yo can in Unix. Welcome to the world of z/OS. Alan Hi to you all! This is my fist post to this list. I'm "playing" with z/OS, and I know that the smf data sets are sys1.man1. How can I see what are the users who access and their permissions to sys1.man1 Thanks ---------------------------------------------------------------------- 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
