Starting in Version 9.7 Fix Pack 3, you can activate the license key for DB2 Connect Unlimited Edition for System z on any z/OS subsystem or data sharing group that you want to access directly. Activating the license key on a z/OS subsystem can take less time than activating the key on each client computer. You can activate the license only on a z/OS subsystem or data sharing group for which the product was purchased. Activation is done using the db2connectactivate utility.
 
With or without IBM APAR IC82415, there is some manual intervention needed for those who deployed DB2 Connect Unlimited Edition and used the server-based license activation.
