And large page support was documented in the V10 announcement. http://www.ibm.com/common/ssi/cgi-bin/ssialias?infotype=AN&subtype=CA&appname=gpateam&supplier=897&letternum=ENUS210-380&pdf=yes "Customers with large buffer pools that are page fixed (standard) and z10 or zEnterprise machines will use large pages and require the following z/OS APARs: – z/OS V1.10: APARs OA24441, OA25169, OA25485, OA27799, OA31116, OA32001, and OA32668 – z/OS V1.11 and V1.12: APARs OA32001, OA31116, and OA32668" And what I may be remembering at SHARE was a verbal reference to DB2 X in Elpida's Large Page session for z/OS 1.9 in San Jose. Maybe I just always assumed DB2 V10 would have the REUSASID support.
