Db2 z/OS real storage management (Case TS006310627)

After the observation of a significantly increase of the CPU consumption in our Db2-MSTR regions, we opened case TS006310627 at IBM since the reason was not evident. The result of the analysis with IBM showed up that probably APAR PH31684 caused the increase in CPU. This seems to be due to the introduction of the SORTL capability, which increased the memory requirement during queries with ORDER BY or GROUP BY sort. The overall increase itself was not dramatically, but the allocation and free process of the 64 bit real storage using IARV64 DISCARDDATA operation increased the CPU consumption for the MSTR address spaces.

We are looking forward and appreciate that IBM is streamlining the DISCARDDATA process in a future release of Db2 z/OS. For the time being we will keep the Db2 ZPARM REALSTORAGE_MANAGEMENT set to OFF.
