There have been several customers on DB2 10 who have taken partial dumps of DB2 even with MAXSPACE set at 16GBs-32GBs. Much of this has to do with the increased use of 64-bit addressing in DB2 10 and the way z/OS treats the address space to be dumped. The shared storage pools above the 2GB bar are large, but sparsely populated, and thus should not take up much room in the dump. DB2 level 2 has seen much of this storage being dumped inadvertently. These APARs have to do with extra storage being dumped in some cases, and not enough being dumped in others.
· OA39596 – excessive HVSHARE storage included in DUMPs when it is not needed
· OA40015 – SVCDUMP missing high virtual user region storage
· OA40015 – High virtual regions missing from dump
