Enabling partner LU verification

With RACF® and VTAM®, you can control whether two logical units (LU) that use LU 6.2 can connect to each other.

About this task

Each member of a connecting pair must establish a profile for the other member. For example, if LUAAA and LUBBB are to connect and know each other by those LUNAMES, issue RACF commands similar to these:

  • At LUAAA: RDEFINE APPCLU netid.LUAAA.LUBBB UACC(NONE) …
  • At LUBBB: RDEFINE APPCLU netid.LUBBB.LUAAA UACC(NONE) …

Here, netid is the network ID, given by the VTAM start option NETID.

When you create those profiles with RACF, use the SESSION operand to supply:

  • The VTAM password as a session key (SESSKEY suboperand)
  • The maximum number of days between changes of the session key (INTERVAL suboperand)
  • An indication of whether the LU pair is locked (LOCK suboperand)

Finally, to enable RACF checking for the new APPCLU resources, issue this RACF command at both LUAAA and LUBBB:
