## Synergy with the IBM Z platform 

As with previous Db2 versions, Db2 12 for z/OS takes advantage of the latest improvements that are available on the IBM Z platform. Db2 12 increases its synergy with z Systems hardware and software to provide better performance, stronger resilience, and better functions for an overall improved value. 

Db2 12 also adds more z Systems Integrated Information Processor (zIIP) eligibility, and can use zEDC cards to enable LOB compression.
