Specifying a generic LU name and IPNAME value for the data sharing group

If you use RACF® PassTickets for security, you must define either a generic LU name for the data sharing group, an IPNAME for the data sharing group, or both.

If all members of the data sharing group are to be configured to enable TCP/IP communications only, then all members of the data sharing group must share the same IPNAME value. You can use the DB2 TCP/IP IPNAME field of panel DSNTIPR or the DSNJU003 (change log inventory) utility to define the IPNAME value. If all of the members of the data sharing group are to be configured to enable both SNA/APPC and TCP/IP communications, then all members of the data sharing group must share the same generic LU name. Use the DB2 GENERIC LUNAME parameter on installation panel DSNTIPR or use the DSNJU003 (change log inventory) utility to define the generic LU name.

If some of the members of the data sharing group are to be configured to enable TCP/IP communications only and the others are to enable both, then the IPNAME value of the TCP/IP only members must match the generic LU name of the members that enable both TCP/IP and SNA/APPC communications. The generic LU name or IPNAME value is used as the RACF application name when validating a RACF PassTicket at any member of the data sharing group.
