OIM 11g R2 : Change Display Name on change of First Name or Last Name

This post covers the sample code for an event handler that modifies the Display Name whenever there is a change in first name or last name.

This feature is not available out-of-the-box

Event Handler runs on Modify operation for single event as well as a bulk event like trusted reconciliation.
