Hello ,
I'm looking for an explanation about an issue I found regarding 'OMVS UID' and APPLICATION DATA of BPX.NEXT.USER eventual interaction .
Basically , in the system BPX.NEXT.USER is here (in case of the userid does not have an OMVS segment (and other criterias) -> the user will receive a OMVS segment based on a model and the next valid UID will be given to this userid ) .
Few month ago , in order to list (all the userids sorted and their assigned UID , their connected group with their GID) a built CARLA request or a generated from the zsecure menus was used . And the consequence apparently is that this resulted with the users being assigned an OMVS segment with an incremented 'defaulted' UID.
getUmap generating an SMF type 80 record (event 88) with a new UID
getGmap generating an SMF type 80 record (event 88) with a new GID is assigned
Also , apparently , that the RACF USER LAST-ACCESS field is not updated .
Could you please , inform about/explain that which kind of CARLA code/function does that ?
How this interaction with the UIDs range values included in APPLICATION DATA of BPX.NEXT.USER ?
How it's possible to rever back the previous UIds values ?
And how to prevent such getUmap/getGmap done by CARLA code in the active RACF database ?
Thank you .

As you can see in the report the user are sorted alphabetically and Uid assigned is order incrementally : that's why I suspected such thing .
Then , does CARLA code/or generated via zSECURE menus can do that ?
