Customers have more flexibility by using the UUID based SAP License keys
Problem: SAP License keys have been bound to the underlying HW key demanding to generate for LPM a key per potential target host.
Solution: IBM and SAP changed the key generation to use the LPAR ID (UUID) which does not change when moving from on server to the other.
By that customers have to generate and install for each message server a single license key by applying the procedure described in SAP Note 2879336.
Furthermore, unplanned downtimes after a message server restart with missing license for the server is eliminated.
