DB2 maintenance includes PTF UI67918 / APAR PH18956. The hold data indicates that "after application of this PTF, the external security system must be updated to use the package owner information provided in the XAPLREL1 field for drop or free package authorization".
Does ACF2 for DB2 or ENF require anything in order to accommodate this PTF?
