Hi Frank, The short answer is 'yes, you can have the same UID across LPARs/RACF environments'. Longer answer is that it may not be as easy as you'd like depending on how your RACF environments are set up. There are several RACF FACILITY class profiles (like BPX.NEXT.USER and BPX.UNIQUE.USER) that may trip you up. You'll need to chat with your security admins. BPX.UNIQUE.USER says that every different RACF ID needs a unique unix UID. BPX.NEXT.USER is a convenient way to just have RACF assign unique UID/GID values as new users are given OMVS segments in RACF. Typically what I've seen is the RACF admin will set a base "next user" and allow RACF to assign users as needed, but they will reserve a range of UIDs for situations like yours where you need a hard-coded UID. As Radoslaw (at least I think is was him) mentioned, you'll need to do the chown jockeying to get your directory tree set to the appropriate UID/GID as part of synchronizing the UIDs.
Bottom line is yes, your RACF admin can manually assign a UID/GID to your RACF userIDs and they can be the same across RACF environments.

For "some reason" we have separate RACF databases for each of our environments (dev/test vs production). Because of this (I think it's the reason!) my Unix UID is different in production than in dev/test. This means that even though my personal Unix file system is mounted at the same mount point in each, only in one of them (dev/test) do I technically "own" it. I'm wondering if there might be some way I can "own" it in both systems. Can UIDs be explicitly set to a particular value? Or can one be mapped to another? Or something else? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- The information contained in this message is confidential, protected from disclosure and may be legally privileged.
