MAX_QUERYDEGREE allows to specify the maximum degree of parallelism for a query. The setting of ANY is usually to aggressive for typical Db2 SAP systems. Specifying an absolute value has the disadvantage of having to adjust the parameter for every database based on the available hardware (cores). Allowing a kind of formula, e.g. CORES_PER_SOCKET or CORES_PER_SOCKET-2 CONFIG_CPU or CONFIG_CPU * 0.5 (see db2pd -osinfo) would allow a quite general setting, but resulting in an actual value based on the particular hardware used.
$ UPDATE DB CFG for using MAX_QUERYDEGREE CORES_PER_SOCKET
$ UPDATE DB CFG for using MAX_QUERYDEGREE CORES_PER_SOCKET - 2
$ UPDATE DB CFG for using MAX_QUERYDEGREE CONFIG_CPU * 0.5
