If your DB2 uses VM Dataspaces, it will profit of tyhe extra storage your z/VM system has, but, you may have to check DB2's TARGETWS parameter, this can limit the storage DB2 can occupy, simplified: if DB2 finds out it has more pages resident than that number, it will tell CP to get rid of some of its pages.
