The error message below is seen when trying to access OMVS on an LPAR secured with ACF2:
FSUM2159I No session was started. This TSO/E user ID has no defined UID.
Release : 16.0
Component :
LIST the OMVS profile record. The commands to do this from TSO ACF2 are:
SET P(USER) DIV(OMVS)
LIST logonid
If there is no record found, an OMVS profile record will need to be created:
SET P(USER) DIV(OMVS)
INSERT logonid HOME(home-directory) OMVSPGM(program) UID(uid)
Note that this is a sample. Additional fields can be found in the ACF2 documentation section OMVS User Profile Records.
After changes to OMVS User profile records, the following console commands are necessary only for shared database environments:
F ACF2,REBUILD(USR),CLASS(P),DIV(OMVS)
F ACF2,OMVS(UID)
These will need to be issued on each system that is sharing the database.
