Define RSE as a secure z/OS UNIX server

RSE requires UPDATE access to the BPX.SERVER profile to create and delete the security environment for the client's thread. If this profile is not defined, UID(0) is required for RSE.
  • RDEFINE FACILITY BPX.SERVER UACC(NONE)
  • PERMIT BPX.SERVER CLASS(FACILITY) ACCESS(UPDATE) ID(STCRSE)
  • SETROPTS RACLIST(FACILITY) REFRESH
Attention: Defining the BPX.SERVER profile makes z/OS® UNIX as a whole switch from UNIX level security to z/OS UNIX level security, which is more secure. This switch might impact other z/OS UNIX applications and operations. Test the security before activating the profile on a production system.
